Description

Technical Field

[0001] This invention relates to the field of SIM card trays, specifically to an automatic SIM card tray retractor. Background Technology

[0002] like Figure 1 As shown, a SIM card tray is a component in mobile phones or 3C electronic products that carries a SIM card and enables the SIM card to connect with other parts for data communication. In industrial production, the inner layer of the SIM card tray is a metal structure, and the outer layer is covered with plastic. The production process involves placing the connecting strip of the metal structure in a mold, and then forming the initial blank of the SIM card holder on the surface of the metal strip through injection molding. The initial blank of the injection-molded SIM card tray needs to be separated from the strip for subsequent operations. In order to separate the SIM card tray from the strip, considering efficiency and separation accuracy, it is necessary to develop an automated SIM card tray automatic disassembly machine. Summary of the Invention

[0003] One object of the present invention is to provide an automatic SIM card tray folding machine, which solves the technical problem of slow speed in the prior art due to the manual separation of the SIM card tray from the material strip.

[0004] The technical solution of this invention is implemented as follows: An automatic SIM card tray bending machine includes a frame, a worktable mounted on the frame, a feeding rotating carrier at one end of the worktable, and a support platform horizontally arranged on the worktable.

The cross-section of the tapered rods is rhomboid. The two rows of tapered rods are staggered. The end side of the tapered rods is a pointed structure. A first gear is fixedly connected to the side wall of the drive shaft. A second gear is fixedly connected to the side wall of the driven shaft. The tooth surfaces of the first gear and the second gear mesh. A support rod is fixedly installed on the surface of the rectangular plate. A first motor is fixedly installed on the end side of the support rod. The output end of the first motor is fixedly connected to the drive shaft.

[0006] A sorting device is disposed on the surface of the workbench. The sorting device includes a first positioning seat and a second positioning seat fixedly connected to the surface of the workbench. A drive wheel and a driven wheel are rotatably mounted inside the first and second positioning seats. A conveyor belt is driven to the outer side of the drive wheel and the driven wheel. A second motor is fixedly connected to the surface of the first positioning seat. The output end of the second motor is fixedly connected to the end side of the drive wheel. A mounting frame is fixedly connected to the surface of the workbench. An automatic telescopic rod is fixedly mounted on the inner side of the mounting frame. A stop bar is fixedly connected to the output end of the automatic telescopic rod. A connecting frame is fixedly mounted on the upper side of the first and second positioning seats.

[0007] Furthermore, one side of the support platform is provided with a channel for the material belt to pass through, and the other side is provided with a chute for the material fixing mechanism to slide.

[0008] Furthermore, the pushing mechanism includes a first drive cylinder fixedly installed on the support platform at one end of the feeding rotating carrier and a slider installed in the slide groove.

[0009] Furthermore, the material setting mechanism includes a connecting seat mounted on the slider and connected to the first driving cylinder, a second driving cylinder mounted on the connecting seat and arranged perpendicularly to the material strip, and a pin connected to the second driving cylinder for insertion into a hole on the edge of the material strip.

[0010] Furthermore, the cutting and pressing mechanism includes a lever located on the support platform, a column located on one side of the support platform and hinged to the middle of the lever, a third drive cylinder connected to one end of the lever, and a cutting blade installed on the other end of the lever for cutting the material strip reservation line and the small connecting strip located on one side of the reservation line.

[0011] Furthermore, the breaking mechanism includes a slidable base installed on the side adjacent to the cutting and pressing mechanism, a fourth driving cylinder provided at the end of the base away from the support platform for driving the base to slide, and a breaking component fixedly installed on the base for breaking the material strip reservation line and the small connecting strip located on the side of the reservation line.

[0012] Furthermore, the breaking assembly includes a fifth drive cylinder mounted on the base, a sliding plate slidably connected to the fifth drive cylinder, a support block fixedly connected to the base, and a clamping block mounted on the support block for breaking the connection between the material strips.

[0013] Furthermore, the card holder pressing mechanism includes a cam motor located on the other side of the support platform, a mounting base connected to the cam motor, a sixth drive cylinder mounted on the mounting base and arranged perpendicularly to the material belt, and a pressure plate connected to the sixth drive cylinder for pressing the card holder.

[0014] Furthermore, both the drive shaft and the driven shaft are internally threaded with drive rods, and the drive rods are internally rotatably connected to the support plate.

[0015] Furthermore, a third motor is fixedly installed on the inner side of the connecting frame, and a rotating shaft is fixedly installed on the output end of the third motor. Several bristles are evenly fixedly connected to the side wall of the rotating shaft, and both ends of the bristles are fixedly connected to the side wall of the rotating shaft. The several bristles form a lantern structure.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. This automatic folding machine completes the segmentation and separation of the material belt with the tray through the sequential action of each component. It has a high degree of automation, saves time and labor, and realizes the material belt conveying through the pushing component and the fixing component, eliminating the need for conveyor belt conveying, saving costs. At the same time, it makes the separation of the material belt and the tray more accurate. The cutting and pressing mechanism composed of lever structure makes the structure simpler and saves manufacturing costs.

[0018] 2. By setting up a pre-treatment device and adjusting the position of the support plate, the force of the cone rod being inserted into the material strip for dotting is flexibly adjusted, further improving the dotting effect during the material strip conveying process. The dotting work on the surface of the material strip reduces the resistance of the material strip during the cutting process with the cutting knife, improving the efficiency of subsequent cutting of the material strip. Furthermore, the pre-dotting work on the surface of the material strip improves the accuracy of subsequent cutting of the material strip, thereby improving the efficiency of the folding machine to a certain extent.

[0019] 3. By setting up a sorting device, when the material belt is broken, the tray and the material belt will fall together onto the surface of the conveyor belt. The second motor is started, and the second motor drives the conveyor belt to move between the drive shaft and the driven shaft. At this time, the tray and the material belt can be conveyed together. When the material belt moves to the surface of the stop bar, the material belt will pass through the space between the stop bar and the conveyor belt and continue to be conveyed until it falls onto the worktable. Since the thickness of the tray is greater than that of the material belt, the tray will be stuck on the surface of the stop bar. At this time, the automatic telescopic rod is activated, which will drive the stop bar to move. The stop bar will drive the tray to fall from the other side of the conveyor belt, thereby realizing the sorting and processing of the material belt and the tray. This reduces the phenomenon of sorting errors that are easily caused by subsequent manual sorting. By setting up a sorting device, the sorting of broken material belt and tray is facilitated, avoiding the missorting that is easily caused by manual sorting, and further improving the sorting efficiency of the automatic material folding machine.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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 some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] like Figures 1 to 5As shown, this embodiment provides an automatic SIM card tray folding machine, including a frame 1, a worktable 2 mounted on the frame 1, a feeding rotating tray 3 at one end of the worktable 2, the feeding rotating tray 3 being located at the left end of the worktable 2, the material strip 100 of the feeding rotating tray 3 being conveyed from the left side along the right side, the worktable 2 also having a support platform 9 for supporting a pushing mechanism 4 and a fixing mechanism 5, one side of the support platform 9 having a channel for the material strip 100 to pass through, and the other side having a slide groove 90 for the fixing mechanism 5 to slide, when the material strip 100 of the feeding rotating tray 3 passes along the worktable 2 and enters the fixing mechanism 5, the pushing mechanism 4 includes a feeding tray fixedly installed near the support platform 9. The first drive cylinder 41 at one end of the rotating carrier 3 and the slider 42 installed in the slide 90 are used to fix the material belt 100. The material fixing mechanism 5 includes a connecting seat 51 installed on the slider 42 and connected to the first drive cylinder 41, a second drive cylinder 52 installed on the connecting seat 51 and perpendicular to the material belt, and a pin 53 connected to the second drive cylinder 52 and used to insert into the hole 101 on the side of the material belt 100. When the material belt 100 enters below the connecting seat 51, the second drive cylinder 52 works to insert the pin 53 into the hole 101 on the side of the material belt 100 for fixing. Then the first drive cylinder 41 works to push the connecting seat 51 to realize the feeding action.

[0034] The material strip 100 is pushed to the cutting and pressing mechanism 6, which is used to cut the reservation line 102 of the material strip 100 and press the material strip 100 together. The cutting and pressing mechanism 6 includes a lever 61 located on the support platform 9, a column 62 located on one side of the support platform 9 and hinged to the middle of the lever 61, a third drive cylinder 63 connected to one end of the lever 61, and a cutting blade 64 installed on the other end of the lever 61 for cutting the reservation line 102 of the material strip 100. The cutting blade 64 is provided with an inclined notch 641 at the reservation line 102 of the material strip 100. When the reservation line 102 of the material strip 100 enters the narrow part of the notch 641, it is cut and the cut is pressed at the same time. By adopting a lever structure, the cutting blade 64 can achieve the cutting function by making the third drive cylinder 63 work.

[0035] After being cut, the strip 100 is now only connected to the small connecting strip 104 between the strip 100 and the tray 103. It then enters the tray pressing mechanism 8. The tray pressing mechanism 8 includes a cam motor 81 located on the other side of the support platform 9, a mounting base 82 connected to the cam motor 81, a sixth drive cylinder 83 mounted on the mounting base 82 and perpendicular to the strip 100, and a pressure plate 84 connected to the sixth drive cylinder 83 for pressing the tray 103. When the pressure plate 84 presses the tray 103, the cam motor 81 drives the mounting base 82 to rotate, causing the tray 103 to disconnect from the small connecting strip 104 in the strip 100. After disconnection, the strip 100 with the tray 103 removed is connected to the strip 100 with the tray 103.

[0036] Subsequently, the breaking mechanism 7 operates. The breaking mechanism 7 includes a slidable base 71 installed adjacent to the cutting and pressing mechanism 6, a fourth drive cylinder 72 for driving the base 71 to slide at one end of the base 71 away from the support platform 9, and a breaking assembly 73 fixedly installed on the base 71 for breaking the material strip 100 between the two strips. The breaking assembly 73 includes a fifth drive cylinder 731 installed on the base 71, a sliding plate 732 connected to the fifth drive cylinder 731, a wave-shaped slide rail 7321 inside the sliding plate 732, wherein the sliding plate 732 is installed perpendicularly to the base 71, a support block 733 is fixedly connected to the base 71, the bottom of the support block 733 is located in the wave-shaped slide rail 7321, and a component installed on the support block 733 for breaking the material strip 100 between the two strips. The clamping block 734, which is broken at the connection 105 between 100, is composed of an upper clamping block 7341 and a lower clamping block 7342. A gap 7343 is left between the upper clamping block 7341 and the lower clamping block 7342 to allow the material strip 100 to pass through. When the material strip 100 enters the working area of ​​the breaking mechanism 7, the fourth drive cylinder 72 pushes the base 71 close to the material strip 100 until the material strip 100 enters the gap 7343 between the upper clamping block 7341 and the lower clamping block 7342. Then, the fifth drive cylinder 731 pushes the sliding plate 732 to reciprocate, causing the support block 733 to jump up and down along the wave-shaped slide 7321 in the sliding plate 732 until the material strip 100 with the removed clip 103 and the material strip 100 with the clip 103 are broken, thus completing the breaking process.

[0037] A pretreatment device 10 is disposed on the surface of the workbench 2. The pretreatment device 10 includes a rectangular plate 1001 fixedly mounted on the surface of the workbench 2. A drive shaft 1004 and a driven shaft 1003 are rotatably mounted inside the rectangular plate 1001. Two slide bars 1008 are slidably connected inside the drive shaft 1004 and the driven shaft 1003. Support plates 1009 are fixedly mounted on the end sides of the two slide bars 1008. A row of tapered rods 1011 are uniformly fixedly connected to the surface of the support plate 1009. The cross-section of the tapered rods 1011 is rhomboid. The two rows of tapered rods 1011 are staggered. The end sides of the tapered rods 1011 are pointed structures. A first gear 1007 is fixedly connected to the side wall of the drive shaft 1004. The driven shaft 1003... A second gear 1006 is fixedly connected to the side wall of the first gear 1007, and the tooth surfaces of the first gear 1007 and the second gear 1006 mesh with each other. A support rod 1005 is fixedly installed on the surface of the rectangular plate 1001, and a first motor 1002 is fixedly installed on the end side of the support rod 1005. The output end of the first motor 1002 is fixedly connected to the drive shaft 1004. Both the drive shaft 1004 and the driven shaft 1003 are threadedly connected to drive rods 1010. The drive rods 1010 are rotatably connected to the inside of the support plate 1009. By setting the pre-treatment device 10, when the material belt 100 moves to the processing position and is broken during the conveying process of the material belt 100, the first motor 1002 is started. 2 will drive the drive shaft 1004 to rotate, and the first gear 1007 on the drive shaft 1004 will move relative to the second gear 1006. At this time, the driven shaft 1003 can be driven to rotate. During the relative rotation between the drive shaft 1004 and the driven shaft 1003, when the rows of cone rods 1011 flip to face the surface of the material strip 100, the cutting position on the surface of the material strip 100 can be marked. The two rows of cone rods 1011 arranged in an alternating manner improve the tightness of the marking on the material strip 100 and improve the marking effect. By rotating the drive rod 1010, the position of the support plate 1009 can be adjusted. The slide bar 1008 is located on the main... The sliding of the moving shaft 1004 or driven shaft 1003 inside restricts the movement direction of the support plate 1009. By adjusting the position of the support plate 1009, the force of the cone rod 1011 inserted into the material strip 100 for dotting is flexibly adjusted, further improving the dotting effect during the conveying of the material strip 100. The dotting work on the surface of the material strip 100 reduces the resistance of the material strip 100 during the cutting process using the cutting blade 64, improves the efficiency of subsequent cutting of the material strip 100, and improves the accuracy of subsequent cutting of the material strip 100, thereby improving the efficiency of the folding machine to a certain extent.

[0038] A sorting device 11 is installed on the surface of the workbench 2. The sorting device 11 includes a first positioning seat 1101 and a second positioning seat 1102 fixedly connected to the surface of the workbench 2. A drive wheel 1105 and a driven wheel 1104 are rotatably mounted inside the first positioning seat 1101 and the second positioning seat 1102. A conveyor belt 1103 is driven to the outer side of the drive wheel 1105 and the driven wheel 1104. A second motor 1108 is fixedly connected to the surface of the first positioning seat 1101. The output end of the second motor 1108 is fixedly connected to the end side of the drive wheel 1105. A mounting bracket 1107 is fixedly connected to the surface of the workbench 2. An automatic telescopic rod 1106 is fixedly mounted on the inner side of the mounting bracket 1107. The output end of the automatic telescopic rod 1106 is fixedly connected to... There is a baffle 1113. A connecting frame 1109 is fixedly installed on the upper side of the first positioning seat 1101 and the second positioning seat 1102. A third motor 1110 is fixedly installed on the inner side of the connecting frame 1109. A rotating shaft 1111 is fixedly installed at the output end of the third motor 1110. Several bristles 1112 are evenly fixedly connected to the side wall of the rotating shaft 1111. Both ends of the bristles 1112 are fixedly connected to the side wall of the rotating shaft 1111. The several bristles 1112 form a lantern structure. By setting a sorting device 11, when the material belt 100 is broken, the card holder 103 and the material belt 100 will fall together on the surface of the conveyor belt. The second motor 1108 is started. The second motor 1108 will drive the conveyor belt 1103 on the drive shaft 1004 and Driven by the surface of the driven shaft 1003, the material belt 100 and the tray 103 on the conveyor belt 100 can be conveyed together. When the material belt 100 moves to the position of the stop bar 1113, it will pass through the position between the stop bar 1113 and the conveyor belt 1103 and continue to be conveyed until it falls onto the worktable 2. Since the thickness of the tray 103 is greater than that of the material belt 100, the tray 103 will be stuck on the surface of the stop bar 1113. At this time, the automatic telescopic rod 1106 is activated, which will drive the stop bar 1113 to move. The stop bar 1113 will then drive the tray 103 to fall from the other side of the conveyor belt 1103, thereby realizing the sorting and processing of the material belt 100 and the tray 103, reducing the subsequent burden. The sorting process by staff can easily lead to misclassification. To address this, during the activation of the second motor 1108, the third motor 1110 is simultaneously activated. The third motor 1110 drives the rotating shaft 1111 to rotate, thus rotating the brush 1112 that mounts the lantern structure. During this process, the brush 1112 simultaneously rotates the conveyor belt 100 and the tray 103 until they rotate to the side of the conveyor belt 100 closest to the baffle 1113. This prioritizes the conveyor belt 100 passing through the baffle 1113, preventing the tray 103 from being in front of the conveyor belt and interfering with its passage. This further improves the sorting efficiency of the conveyor belt 100 and the tray 103.Furthermore, by setting up the brush bristles 1112, the sidewalls of the brush bristles 1112 can be used to clean the debris from the broken surface of the card tray 103, improving the efficiency of the card tray 103 breaking process. By using the brush bristles 1112 to drive and clean the surface of the card tray 103, the cleaning caused by the brush bristle tips touching the surface of the card tray 103 can be avoided. Moreover, the bent brush bristles 1112 have good elasticity, which can improve the driving effect on the card tray 103 and the material belt 100. The classification device 11 facilitates the classification of the broken material belt 100 and card tray 103, avoiding the misclassification that is easily caused by manual classification, further improving the breaking efficiency of the automatic breaking machine.

[0039] The above embodiments are preferred embodiments of the present invention, but the embodiments of the present invention are not limited thereto. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present invention are equivalent substitutions and are included within the protection scope of the present invention.
