Description

Technical Field

[0001] This invention relates to the field of fully automated machining centers for mobile phone metal casings, and particularly to an automatic door opening device for a machining center used in the production of mobile phone components. Background Technology

[0002] In the process of processing the metal casing of mobile phones, it is necessary to cut the metal block to carve out the shape of the mobile phone casing or frame. The existing processing method is mostly to use machining center processing, that is, to load the metal material into the machining center and complete the carving process of the metal material through the CNC machining center.

[0003] Because the processing of metal casings or frames for mobile phones requires manual loading and unloading, workers need to constantly monitor the processing progress of the machining center and replace metal materials in a timely manner. This greatly limits the number of machining centers that workers can monitor. Therefore, the market is developing fully automated loading and unloading technology for metal materials. To achieve fully automated loading and unloading of metal materials, the sliding doors of the machining center need to be converted from manual to automatic opening. Conventional automatic opening methods for sliding doors in machining centers are either through cylinders or linear slides. However, regardless of whether it is opened by a cylinder or a linear slide, a self-locking device is used to prevent accidental opening of the sliding door during the processing. For example, if a cylinder-driven sliding opening structure is used, a pneumatic pressure holding method is adopted to achieve self-locking. This technical problem is mentioned in Chinese invention patent application No. 202510492233.6.

[0004] Using a linear slide to open the sliding door involves using an electromagnetic brake to lock the linear slide. This means that if the machining center experiences a power outage, the sliding door cannot be opened, creating a technical problem that prevents maintenance workers from performing repairs.

[0005] Therefore, there is an urgent need for a technical solution that can both enable the automatic opening of the sliding door of the machining center and meet the manual opening requirements under specific circumstances. Summary of the Invention

[0006] To address the above problems, this invention provides an automatic door opening device for a machining center used in mobile phone component production. Based on the existing technology of automatic opening of sliding doors controlled by electric slide tables, a locking mechanism is provided. This allows the electric slide table to drive the sliding door to open, and under certain circumstances, the sliding door can be manually opened by manually releasing the locking mechanism.

[0007] To achieve the above objectives, the present invention provides the following technical solution: An automatic door opening device for a machining center used in mobile phone component production includes: Body, sliding door mechanism, automatic door opening mechanism and locking mechanism; The sliding door mechanism is installed at the inlet and outlet of the machine body, and the sliding door mechanism opens and closes the inlet and outlet. The sliding door mechanism includes two sets of sliding doors that are slidably arranged, with the two sets of sliding doors overlapping and stored together. The automatic door opening mechanism is installed on the machine body. The automatic door opening mechanism is connected to any of the sliding doors through a locking mechanism. The automatic door opening mechanism pulls the sliding door to slide. The locking mechanism is disposed between the automatic door opening mechanism and the corresponding sliding door. The locking mechanism includes a connecting component and a switching component. The connecting component connects the automatic door opening mechanism and the sliding door. The switching component manually disconnects the connection between the connecting component and the sliding door.

[0008] As an improvement, the machine body includes a base and a housing. The base has a sliding groove with the opening facing downwards. The housing has the inlet and outlet ports, and a slide rail is provided on top of the inlet and outlet ports.

[0009] As an improvement, the sliding door mechanism further includes a suspension wheel, a suspension connecting seat, a fastening wheel, and a fastening connecting plate. The suspension wheel is installed on the top of the sliding door through the suspension connecting seat. The suspension wheel has an upward-facing groove that engages with the slide rail and rolls. The fastening wheel is installed at the bottom of the sliding door via the fastening connecting plate. The fastening wheel is horizontally positioned and is fastened to the sliding groove.

[0010] As an improvement, the sliding door connected to the automatic door opening mechanism is provided with a handle, and a limit plate is installed on the side of the sliding door that connects with another set of sliding doors. When the automatic door opening mechanism drives the corresponding sliding door to close the inlet / outlet, the sliding door drags the other set of sliding doors to slide through the limit plate.

[0011] As an improvement, the automatic door opening mechanism includes an electric slide and a mounting base. The electric slide is arranged parallel to the direction of the slide rail. The mounting base is installed on the slide base of the electric slide and is connected to the connecting assembly.

[0012] As an improvement, the connecting assembly includes two sets of lock housings and lock tongues arranged in a centrally symmetrical manner. One set of lock housings is connected to the mounting base, and the other set of lock housings is installed on the corresponding sliding door. Two sets of lock tongues are provided, and the lock tongues are rotatably installed in the corresponding lock housings.

[0013] As an improvement, each of the latches includes a semi-circular tongue with an arc-shaped limiting groove. The lock housing is provided with a limiting block that corresponds to and cooperates with the limiting groove. When the two sets of latches are rotated to the point where the joint of the tongue is inclined, the connecting component connects the mounting base to the sliding door. When the joint of the tongue is horizontal, the connecting component disconnects the mounting base from the sliding door.

[0014] As an improvement, the latch inside the lock housing, which is installed and connected to the sliding door, also includes a swing arm extending outward from the tongue. A tension spring is installed between the swing arm and the lock housing, and the swing arm is hinged to the swing rod via a connecting rod. A pin is installed at the swing end of the swing rod, and a groove is provided on the mounting base. The pin is inserted into the groove.

[0015] As an improvement, the switching assembly includes a spline shaft, an operating lever, and a hinge arm. The spline shaft is rotatably mounted on the sliding door. The operating lever is fixedly connected to the spline shaft and is located on the outer wall of the sliding door. The operating lever drives the spline shaft to rotate. One end of the hinge arm is connected to the spline shaft through a keyway, and the other end of the hinge arm is hinged to the connecting rod.

[0016] As an improvement, the switching assembly also includes a support limiting rod, which is slidably mounted on the outer wall of the sliding door via a slider. The slider is provided with an elastic element that drives it to reset. When the operating rod drives the latch to rotate and the connection state of the connecting assembly is released, the support limiting rod supports and limits the operating rod, so that the latch joint remains horizontal.

[0017] The beneficial effects of this invention are as follows: (1) The present invention, based on the existing technology of controlling the automatic opening of the sliding door by the electric slide table, sets up a locking mechanism. When the locking mechanism is in the locked state, the electric slide table can drive the sliding door to open. At the same time, under certain circumstances, the locking mechanism can be manually released to realize the manual opening of the sliding door, which is convenient for opening the sliding door for maintenance operations. (2) The locking mechanism of the present invention cleverly uses the rotation of the locking tongue to realize the locking and unlocking of the locking mechanism, making the connection and disconnection between the electric slide and the sliding door very smooth. At the same time, the sliding door and the electric slide can form a stable connection state by relying on the rotation of the locking tongue, so that the electric slide will not disengage when it drives the sliding door to slide. (3) By adopting a switching component, the present invention realizes the connection and unlocking of the connecting component of the locking mechanism. When the switching component realizes the connection of the connecting component, a second connection is formed on the mounting base through the cooperation of the pin and the slot, which serves as a connection supplement to the connecting component. This means that when the electric slide is dragging the sliding door, the connection force does not need to be fully applied to the locking tongue of the connecting component, thus avoiding deformation of the locking tongue after long-term operation and making the connection between the sliding door and the electric slide more stable. (4) By using the combination of the suspension wheel and the fastening wheel, the suspension wheel and the fastening wheel above and below the sliding door will not be affected by the metal waste generated during the metal material carving and cutting process when the sliding door is sliding, thus ensuring the stability of the sliding door and preventing the sliding door from falling off.

[0018] In summary, this invention has advantages such as automation, stability, safety, and reliability, and is particularly suitable for the field of automatic door structure technology in machining centers for mobile phone metal parts. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and 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.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0023] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0024] Example 1: like Figure 1 , Figure 2 , Figure 12 As shown, an automatic door opening device for a machining center used in mobile phone component production includes: 1. Body; 2. Sliding door mechanism; 3. Automatic door opening mechanism; and 4. Locking mechanism; The sliding door mechanism 2 is installed at the inlet / outlet 11 on the machine body 1. The sliding door mechanism 2 opens and closes the inlet / outlet 11. The machine body 1 includes a base 12 and a housing 13. The base 12 has a sliding groove 121 with the opening facing downward, which can effectively prevent metal scrap and cutting fluid generated during the machining process from entering the sliding groove, so as not to interfere with the sliding of the sliding door. The inlet / outlet 11 is provided on the housing 13, and a slide rail 111 is provided on the top of the inlet / outlet 11. The slide rail 111 is located on the top of the inlet / outlet 11 and is horizontally high, so that the slide rail 111 will not be affected by metal scrap and cutting fluid at all. The sliding door mechanism 2 includes two sets of sliding doors 21 that are slidably arranged. The two sets of sliding doors 21 are stacked and stored together. That is, when the sliding door 21 is opened and moved to the limit position, the two sets of sliding doors 21 will directly overlap, so that the inlet and outlet 11 is fully opened. The automatic door opening mechanism 3 is installed on the machine body 1. The automatic door opening mechanism 3 is connected to any of the sliding doors 21 through the locking mechanism 4. The automatic door opening mechanism 3 pulls the sliding door 21 to slide, thereby realizing the automatic opening of the inlet and outlet 11. Then, the robot arm can directly grab metal materials for mounting and grab the formed mobile phone shell or mobile phone frame for output. The locking mechanism 4 is disposed between the automatic door opening mechanism 3 and the correspondingly connected sliding door 21. The locking mechanism 4 includes a connecting component 41 and a switching component 42. The connecting component 41 connects the automatic door opening mechanism 3 and the sliding door 21. The switching component 42 manually disconnects the connection between the connecting component 41 and the sliding door. When the machining center is performing normal processing, the connecting component 41 maintains the connection between the automatic door opening mechanism 3 and the sliding door 21. However, in the event of a power outage or other special circumstances, the connecting component 41 can be manually disconnected by the switching component 42, so that the automatic door opening mechanism 3 is disconnected from the sliding door 21. The sliding door 21 can then be opened manually for easy maintenance.

[0025] Example 2: Referring to Example 1, the difference between Example 2 and Example 1 lies in the following: like Figures 3-4 , Figures 5-10 As shown, the sliding door mechanism 2 also includes a suspension wheel 22, a suspension connecting seat 23, a fastening wheel 24 and a fastening connecting plate 25. The suspension wheel 22 is installed on the top of the sliding door 21 through the suspension connecting seat 23. The suspension wheel 22 has a circumferential groove 221, which is engaged with the slide rail 111 and rotates. The fastening wheel 24 is installed at the bottom of the sliding door 21 via the fastening connecting plate 25. The fastening wheel 24 is horizontally arranged and is fastened to the slide groove 121.

[0026] Specifically, the sliding door 21 of the present invention differs from the existing sliding door in that the sliding door 21 of the present invention is suspended on the body 1, the suspension wheel 22 installed on the top of the sliding door 21 is vertically arranged, the roller groove 221 on the suspension wheel 22 is engaged with the edge of the slide rail 111, and the sliding door 21 moves along the slide rail 111 through the suspension wheel 22.

[0027] Furthermore, the lower part of the sliding door 21 is fastened to the slide rail 121 by a horizontally arranged fastening wheel 24. The slide rail 121 opens downward and is in an inverted U-shape. When the sliding door 21 slides, the slide rail 121 limits the fastening wheel 24. At the same time, the weight of the sliding door 21 prevents the suspension wheel 22 from disengaging from the slide rail 111, thereby ensuring the stable sliding of the sliding door 21.

[0028] Furthermore, it should be emphasized that there are two sets of parallel sliding tracks 121. One end of the sliding track 121 is open and the other end is closed. The two sets of sliding tracks 121 correspond to the two sets of sliding doors 21 respectively. When installing the sliding door 21, the hanging wheel 22 at the top of the sliding door 21 is first fastened to the edge of the slide rail 111 through the roller groove 221. Then, the fastening wheel 24 is inserted into the sliding track 121. As the sliding door 21 slides, the fastening wheel 24 is completely inserted into the sliding track 121. The fastening wheel 24 is completely limited by the side of the sliding track 121, thereby preventing the sliding door 21 from falling off.

[0029] Example 3: Referring to Example 1, the difference between Example 3 and Example 1 lies in the following: like Figure 10 As shown, a handle 211 is provided on the sliding door 21 connected to the automatic door opening mechanism 3, and a limit plate 212 is installed on the side of the sliding door 21 that connects with another set of sliding doors 21. When the automatic door opening mechanism 3 drives the corresponding sliding door 21 to close the inlet / outlet 11, the sliding door 21 drags the other set of sliding doors 21 to slide through the limit plate 212.

[0030] It should be specifically explained that when the automatic door opening mechanism 3 drives the sliding door 21 to slide open the inlet / outlet 11, the automatic door opening mechanism 3 only drives one set of sliding doors 21 to slide. When the sliding door 21 slides to overlap with another set of sliding doors 21, the handle 211 will touch the side of the other set of sliding doors 21. As the automatic door opening mechanism 3 continues to operate, the handle 211 will drive the other set of sliding doors 21 to slide synchronously. Correspondingly, when the automatic door opening mechanism 3 drives the sliding door 21 to slide close the inlet / outlet 11, the sliding door 21 will abut against the side of the other set of sliding doors 21 through the limiting plate 212, thereby driving the other set of sliding doors 21 to move synchronously again, thus realizing the synchronous opening and closing of the two sets of sliding doors 21.

[0031] Example 4: Referring to Example 1, the difference between Example 4 and Example 1 lies in the following: like Figure 2 , Figure 13 As shown, the automatic door opening mechanism 3 includes an electric slide 31 and a mounting base 32. The electric slide 31 is arranged parallel to the setting direction of the slide rail 111. The mounting base 32 is installed on the slide base 311 of the electric slide 31. The mounting base 32 is installed and connected to the connecting component 41.

[0032] It should be noted that in this invention, the mounting base 32 is slidable via an electric slide table 31. The mounting base 32 is connected to the sliding door 21 via a connecting component 41. The mounting base 32 drives the sliding door 21 to slide. Compared to the cylinder-driven sliding method, the electric slide table of this invention can precisely control the door's moving speed, position, and acceleration, with a repeatability accuracy of 0.01–0.1 mm. There is no impact when the door starts and stops, and there will be no "overshooting" or "unstable stopping," making it suitable for scenarios requiring high precision in opening and closing positions.

[0033] Example 5: Referring to Example 1, the difference between Example 5 and Example 1 is as follows: like Figures 14-18 As shown, the connecting component 41 includes two sets of lock housings 411 and lock tongues 412 arranged symmetrically in the center. One set of lock housings 411 is connected to the mounting base 32, and the other set of lock housings 411 is installed on the corresponding sliding door 21. There are two sets of lock tongues 412, which are rotatably installed in the corresponding lock housings 411.

[0034] Each of the latches 412 includes a semi-circular tongue 4121, on which an arc-shaped limiting groove 4122 is provided. The lock housing 411 is provided with a limiting block 4111 that corresponds to and cooperates with the limiting groove 4122. When the two sets of latches 412 are rotated to the point where the joint of the tongue 4121 is tilted, the connecting component 41 connects the mounting base 32 and the sliding door 21. When the joint of the tongue 4121 is horizontal, the connecting component 41 disconnects the mounting base 32 from the sliding door 21.

[0035] like Figures 12-13 As shown, further, the latch 412 inside the lock housing 411, which is installed and connected to the sliding door 21, also includes a swing arm 4123 extending outward from the tongue 4121. A tension spring 4127 is installed and connected between the swing arm 4123 and the lock housing 411. The swing arm 4123 is hinged to the swing rod 4125 through a connecting rod 4124. A pin 4126 is installed at the swing end of the swing rod 4125. A groove 321 is provided on the mounting base 32. The pin 4126 is inserted and engaged with the groove 321.

[0036] It should be noted that the connecting component 41 of the present invention adopts a semi-circular locking tongue structure. One set of lock housings 411 is installed on the mounting base 32, and the other set of lock housings 411 is installed on the sliding door 21. The lock housings 411 connected to the mounting base 32 are located at the upper part, and the lock housings 411 connected to the sliding door 21 are located at the lower part. The two sets of lock housings 411 are arranged in parallel. The locking tongues 412 are rotatably installed inside the corresponding lock housings 411. The rotation angle of the locking tongues 412 is limited by the cooperation of the limiting groove 4122 and the limiting block 4111. That is, the rotation angle of the locking tongues 412 is limited, and the locking tongues will not detach from the lock housings.

[0037] Specifically, during the assembly of the connecting component 41, the tongue 4121 of the latch 412 on the sliding door 21 is kept horizontal, that is, the diameter side of the semi-circular tongue 4121 is horizontal. The diameter side of the latch 4121 on the mounting base 32 can be horizontal or inclined. When the two sets of latches 412 are connected and locked, the two sets of latches 412 are directly interlocked, so that the latches 412 are spliced ​​into a circle. Then the latches 412 are rotated, so that the originally horizontal splice between the latches 412 becomes inclined, so that each set of latches 412 is located in the two sets of lock shells 411 respectively, thereby realizing the connection between the sliding door 41 and the mounting base 32 by the connecting component 41.

[0038] Furthermore, a spring 4127 is provided on the latch 412 located on the sliding door 21. The function of the spring 4127 is to keep the latch 412 on the sliding door 21 in an inclined state, thereby ensuring that the connecting assembly 41 is in a locked connection state.

[0039] When unlocking is required, simply rotate the swing arm 4123 to rotate the latch 412 on the sliding door 21 back to a horizontal position, so that the gap between the two sets of latches 412 returns to a horizontal position, that is, the corresponding latches return to the corresponding lock housings, thus separating the two sets of latches and achieving the purpose of separating the connecting component 41.

[0040] Furthermore, it should be noted that the connection between the sliding door 21 and the electric slide 31 is not only achieved through the lock housing and the lock tongue in the connecting assembly, but also, after the lock tongue completes the misalignment connection, the lock tongue on the sliding door 21 rotates and misaligns, causing the swing arm 4123 to swing. The swing arm 4123 then drives the swing rod 4125 to swing through the connecting rod 4124. The swing rod 4125 causes the pin 4126 to swing into the groove 321 on the mounting base 32. The interlocking cooperation between the pin 4126 and the groove 321 ensures that the connection between the sliding door 21 and the electric slide 31 is not only achieved through the connecting assembly 41, but also through the pin 4126 and the groove 321, thus achieving the connection between the mounting base and the sliding door. This means that when the electric slide drives the sliding door to slide, it not only receives force through the connecting assembly, but also through the cooperation of the pin and the groove, which serves as force compensation, making the connection between the electric slide and the sliding door more stable.

[0041] Example 7: Referring to Example 1, the difference between Example 7 and Example 1 lies in the following: like Figures 11-19 As shown, the switching assembly 42 includes a spline shaft 421, an operating lever 422, and a hinge arm 423. The spline shaft 421 is rotatably mounted on the sliding door 21. The operating lever 422 is fixedly connected to the spline shaft 421. The operating lever 422 is disposed on the outer wall of the sliding door 21, and the operating lever 422 drives the spline shaft 421 to rotate. One end of the hinge arm 423 is connected to the spline shaft 421 through a keyway, and the other end of the hinge arm 423 is hinged to the connecting rod 4124.

[0042] It should be noted that, in order to enable manual switching of locking and disengaging of the connecting component 41, an operating lever 422 is provided on the sliding door 21. The operating lever 422 can drive the spline shaft 421 to rotate. When the spline shaft 421 rotates, it can drive the hinge arm 423 to rotate and swing. The swing of the hinge arm 423 causes the connecting rod 4124 to move. The movement of the connecting rod 4124, in turn, drives the swing arm 4123 on the lock tongue to swing, thereby causing the lock tongue to rotate to a horizontal position, achieving the purpose of disengaging the connecting component 41.

[0043] Example 8: Referring to Example 1, the difference between Example 8 and Example 1 lies in the following: like Figure 11As shown, the switching component 42 also includes a support limiting rod 424, which is slidably mounted on the outer wall of the sliding door 21 via a slider 425. The slider 425 is provided with an elastic element 426 for driving it to reset. When the operating rod 422 drives the latch 412 to rotate and releases the connection state of the connecting component 41, the support limiting rod 424 supports and limits the operating rod 422, so that the joint of the latch 412 remains horizontal. The operating rod 422 is provided with a notch 4220, which can engage with the support limiting rod 424, thereby realizing the support limiting rod 424 supporting and limiting the operating rod 422.

[0044] It should be noted that after the connecting component 41 is separated by swinging the operating lever 422, a support limit lever 424 is provided on the sliding door 21 to maintain the separated state of the connecting component 41. The support limit lever 424 limits the swing of the operating lever 422 to prevent the operating lever 422 from swinging back to its original position, thus maintaining the separation of the connecting component 41. This allows the connecting component 41 to be smoothly separated when the sliding door 21 is slid manually.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
