Description

Technical Field

[0001] This application belongs to the technical field of automatic feeding equipment, and more specifically, it relates to a device and method for preventing overlapping deformation when inserting mold steel sheets. Background Technology

[0002] In the manufacturing process of mobile phone front covers, steel sheets need to be inserted into the mold. Currently, steel sheet feeding machines are used for feeding these sheets. These machines have a five-axis robotic arm that can automatically pick up steel sheets and insert them into the mold, thus replacing manual insertion and greatly improving the production efficiency of steel sheet feeding. However, because steel sheets are usually thin, they are easy to overlap and deform. Therefore, in the actual feeding process, if overlapping steel sheets are inserted into the mold by the robotic arm, it will result in two steel sheets inside the mold, which can easily cause mold damage during mold closing. If the inserted steel sheets are deformed, it will greatly affect the quality of the injection molded product, reduce the product yield, and also cause some damage to the mold. The losses caused by mold damage are multifaceted. First, the most direct loss is the cost of the mold itself. Repair costs for mold damage typically range from 20,000 to 50,000 yuan, and if the mold is scrapped, the loss can reach 100,000 yuan or more. Second, there is indirect loss in production. The repair time for a damaged mold is generally 48 hours. If we calculate based on a two-cavity mold cycle of 13 seconds per mold, then the lost production capacity for a damaged mold for 48 hours is 3600 / 13*2*48 = 24923 pieces. At a unit price of 10 yuan per piece, the production loss is as high as 124,615 yuan per day, not including the waiting costs for subsequent processes. Third, the overlapping and deformation of the steel sheets embedded in the mold can also cause the quality of the injection molded products to fail to meet requirements, affecting delivery, especially the first batch of deliveries, whose quality and delivery schedule will affect the overall order. Therefore, how to prevent mold damage caused by the overlapping and deformation of the embedded steel sheets has become an urgent problem to be solved in this industry. Summary of the Invention

[0012] Optionally, the vibration device includes a vibration rod, a vibration cylinder, and a high-speed air solenoid valve; the high-speed air solenoid valve is connected to the control system and is used to control the up and down movement of the vibration cylinder.

[0013] The loading robot also includes a suction cup mounting frame.

[0017] The signal input / output module is connected to the injection molding control module, and the USB to serial bus module is connected to the material feeding control module. The camera monitoring microprocessor module is connected to the USB to serial bus module, the signal processing module, and the detection indication module. The signal processing module is connected to the signal input / output module, which includes multiple I / O interfaces.

[0018] This application also proposes a method for preventing overlapping deformation during mold steel sheet implantation, which is accomplished using the aforementioned mold steel sheet implantation anti-overlap deformation device. The method for preventing overlapping deformation during mold steel sheet implantation includes the following steps:

[0019] The loading robot moves to the picking position, the suction cup picks up the steel sheet at the picking position and then moves to the vibration position; at the vibration position, the vibration device vibrates the steel sheet picked up by the suction cup up and down;

[0020] After being vibrated, the steel sheets are placed into the positioning slots of the positioning fixture by the loading robot. The first inspection piece checks whether the steel sheets in the positioning slots overlap or deform.

[0021] The loading robot transfers the positioning fixture loaded with qualified steel sheets to the mold. The steel sheets are then inserted into the cavity of the mold. The second inspection unit monitors the steel sheets inside the mold via video to check for overlapping deformation.

[0022] Optionally, a third detection element is provided on the frame next to the material picking position, and the following steps are also included before the loading robot moves to the material picking position:

[0023] The third inspection component checks whether there are steel sheets at the material picking position;

[0024] If the third detection element detects that there is no steel sheet at the picking position, the third detection element sends a feeding signal to the control system. The control system outputs a lifting signal to the feeding rack according to the feeding signal, and the feeding rack is driven to lift the steel sheet to the picking position; the third detection element checks again whether there is a steel sheet at the picking position.

[0025] If the third detection element detects a steel sheet at the material picking position, it sends a material picking signal to the control system. The control system then controls the loading robot to move to the material picking position based on the material picking signal.

[0026] Optionally, the vibration device includes a vibration rod, a vibration cylinder, and a high-speed air solenoid valve; at the vibration position, the vibration device vibrates the steel sheet picked up by the suction cup up and down in the following steps:

[0027] After the loading robot moves to the vibration position, it sends a position arrival signal to the control system. After receiving the position arrival signal, the control system outputs an opening and closing signal to the high-speed air solenoid valve.

[0028] After receiving the opening and closing signal, the high-speed air solenoid valve switches the valve at high speed to control the vibrating cylinder to drive the vibrating rod to move up and down, thereby vibrating the steel sheet.

[0029] Optionally, the positioning groove is provided with a retainer. The first detection element detects whether the steel sheets in the positioning groove overlap or deform, including the following steps:

[0030] The first testing component measures the thickness of the steel sheet located in the positioning groove, obtains the steel sheet thickness measurement value, and transmits it to the control system. The control system compares the obtained steel sheet thickness measurement value with the pre-stored standard value of steel sheet thickness. If the steel sheet thickness measurement value is greater than the standard value of steel sheet thickness, it is determined to be unqualified.

[0031] The first inspection item simultaneously checks whether there is any deformation or misalignment of the steel sheet at the clip position; if there is such a situation, the control system determines it to be unqualified.

[0032] If the result is deemed unqualified, the control system outputs a stop signal to the loading robot, which then stops operating upon receiving the stop signal. Simultaneously, the control system outputs an alarm signal to the alarm module, which then triggers an alarm upon receiving the signal.

[0033] If the result is deemed satisfactory, the control system outputs a continue signal to the loading robot, and the loading robot continues to operate.

[0034] Optionally, the second inspection component involves video monitoring within the mold to check for overlapping deformation of the steel sheets, including the following steps:

[0035] The second inspection piece acquires an image of the steel sheet located in the cavity to form a steel sheet implantation inspection map; the steel sheet implantation inspection map is transmitted to the control system;

[0036] The control system compares the steel plate implantation detection image with the pre-stored steel plate implantation standard image;

[0037] If the steel sheet implantation detection diagram does not match the standard steel sheet implantation diagram, the control system will determine that the steel sheet implantation is unqualified and output a stop signal and synchronous alarm. The feeding robot and the injection molding machine will stop running after receiving the stop signal; at the same time, the abnormal position will be automatically circled on the steel sheet implantation detection diagram.

[0038] If the steel plate implantation test image matches the steel plate implantation standard Figure 1 If the steel sheet is successfully implanted, the control system will determine that the steel sheet is in place and output a mold closing signal. After receiving the mold closing signal, the injection molding machine will close the mold and perform injection molding.

[0039] The beneficial effects of the anti-overlap deformation device for mold steel sheet implantation provided in this application are as follows: Preventing overlap deformation of the steel sheets implanted in the mold can be achieved in several ways: First, the rapid vibration of the steel sheets adsorbed by the suction cups through the vibration device of the feeding mechanism can shake off most of the overlapping steel sheets, greatly reducing the probability of overlap. Then, after the feeding robot places the steel sheets in the positioning fixture, the first detection component can detect whether the steel sheets in the positioning groove have overlap deformation, further reducing the chance of overlap deformation. Finally, after the steel sheets are implanted into the mold cavity, the second detection component located inside the mold can provide video monitoring of whether the steel sheets have overlap deformation. Thus, through these multiple measures—vibration of the vibration device, detection by the first detection component, and video monitoring by the second detection component—overlap deformation of the steel sheets implanted in the mold can be effectively prevented, thereby avoiding mold compression problems. This reduces losses caused by mold compression, ensures product quality, and meets delivery requirements. Attached Figure Description

[0056] This application provides a device and method for preventing overlapping deformation when inserting mold steel sheets.

[0057] Please see Figures 1 to 6 In one embodiment, the mold steel sheet implantation anti-overlap deformation device is used to implant steel sheets 500 into the mold, including a frame 100, a feeding mechanism 200, a positioning fixture 300, a monitoring mechanism, and a control system. Specifically, the feeding mechanism 200 is mounted on the frame 100 and includes a feeding rack 210, a feeding robot 220, and a vibration device 230; multiple steel sheets 500 are stacked in the feeding rack 210, which has a picking position 211; the feeding robot 220 includes a suction cup 223, which is used to pick up the steel sheet 500 at the picking position 211, and a vibration position of the feeding robot 220 is provided above or beside the picking position 211; the vibration device 230 is provided on the feeding robot 220 and located beside the suction cup 223, and the vibration device 230 is used to vibrate the steel sheet 500 adsorbed by the suction cup 223 after the feeding robot 220 runs to the vibration position. A positioning fixture 300 is mounted on the frame 100, and the positioning fixture 300 is provided with a positioning groove 310; the positioning groove 310 is used to place the steel sheet 500 after it has been picked up and vibrated by the loading robot 220. The monitoring mechanism includes a first detection element 410 and a second detection element (not shown); the first detection element 410 is located in the positioning fixture 300, and its detection range includes the steel sheet 500 located in the positioning groove 310; the second detection element is located in the mold, and its detection range includes the steel sheet 500 implanted in the cavity of the mold. The loading rack 210, the monitoring mechanism, the loading robot 220, and the vibration device 230 are all connected to the control system to realize intelligent control of each component by the control system.

[0058] In the corresponding mold steel sheet 500 implantation anti-overlap deformation method, the mold steel sheet implantation anti-overlap deformation device as described above can be used. The method specifically includes the following steps:

[0059] First, the loading robot 220 moves to the picking position 211, and the suction cup 223 picks up the steel sheet 500 at the picking position 211 and then moves to the vibration position; at the vibration position, the vibration device 230 vibrates the steel sheet 500 picked up by the suction cup 223 up and down.

[0060] Then, the vibrated steel sheet 500 is placed into the positioning groove 310 of the positioning fixture 300 by the loading robot 220. The first detection piece 410 detects whether the steel sheet 500 in the positioning groove 310 overlaps or deforms.

[0061] Finally, the loading robot 220 transfers the positioning fixture 300, which is loaded with the qualified steel sheet 500, to the mold. The steel sheet 500 is then inserted into the cavity of the mold. The second inspection component monitors the steel sheet 500 for overlap and deformation within the mold via video.

[0062] Based on this design, in this embodiment, the prevention of overlapping deformation of the steel sheet 500 implanted in the mold can be achieved in several ways: First, by rapidly vibrating the steel sheet 500 adsorbed by the suction cup 223 through the vibration device 230 of the feeding mechanism 200, most of the overlapping steel sheets 500 can be shaken off, greatly reducing the probability of overlapping steel sheets 500; then, after the feeding robot 220 places the steel sheet 500 in the positioning fixture 300, the first detection element 410 can detect whether the steel sheet 500 in the positioning groove 310 has overlapping deformation, so as to further reduce the probability of overlapping deformation of the steel sheet 500; finally, after the steel sheet 500 is implanted into the cavity of the mold, the second detection element set in the mold can realize video monitoring of whether the steel sheet 500 has overlapping deformation. In this way, by taking multiple measures such as vibration of the vibration device 230, detection of the first detection piece 410, and video monitoring of the second detection piece, it is possible to effectively prevent the steel sheet 500 implanted in the mold from overlapping and deforming, thereby avoiding the problem of mold pressing. This can reduce the losses caused by mold pressing, ensure product quality, and meet delivery requirements.

[0063] It should be noted that in this embodiment, the connection between the control system and each component can be wired or wireless. That is, signals can be transmitted via wired means, such as using cables, or wirelessly. The first detection element 410 can, but is not limited to, use fiber optic detection, while the second detection element can, but is not limited to, use photographic imaging detection.

[0064] Please see Figures 1 to 2 as well as Figures 5 to 6In this embodiment, the loading robot 220 further includes a driving device (not shown), a first slide rail 221, and a second slide rail 222. The length extension direction of the first slide rail 221 is perpendicular to the length extension direction of the second slide rail 222. A suction cup 223 is provided at one end of the second slide rail 222 away from the first slide rail 221, and the other end of the second slide rail 222 is slidably connected to the first slide rail 221. The second slide rail 222 is driven by the driving device to move along the length direction of the first slide rail 221. The suction cup 223 and the vibration device 230 are both driven by the driving device to move along the length direction of the second slide rail 222. Specifically, to facilitate the operation of the loading robot 220 and reduce the space occupied by the equipment, the first slide rail 221 is located at the rear of the loading rack 210, the second slide rail 222 is located above the loading rack 210, and the positioning fixture 300 is located beside the loading rack 210 and in front of the first slide rail 221. Here, since the first slide rail 221 and the second slide rail 222 are perpendicular in the horizontal plane, and the rear end of the second slide rail 222 can move along the length direction of the first slide rail 221, i.e., the left and right direction, and the suction cup 223 can move along the length direction of the second slide rail 222, i.e., the front and back direction, the loading robot 220 can be accurately moved above the material picking position 211 by the movement of the second slide rail 222 and the suction cup 223. Then, the suction cup 223, which can move up and down, is controlled to achieve the adsorption of the steel sheet 500 by the suction cup 223.

[0065] Specifically, the vibration device 230 includes a vibration rod 231, a vibration cylinder 232, and a high-speed air solenoid valve (not shown); the high-speed air solenoid valve is connected to the control system and is used to control the up-and-down movement of the vibration cylinder 232. The loading robot 220 also includes a suction cup mounting frame 224, on which the suction cup 223 and the vibration cylinder 232 are mounted, with the vibration cylinder 232 located outside the suction cup 223; the upper end of the vibration rod 231 is connected to the vibration cylinder 232, and the lower end of the vibration rod 231 faces the steel sheet 500. In this embodiment, to improve the stability of the steel sheet 500 being picked up, a suction cup 223 is provided at each end of the suction cup mounting frame 224, and two vibration cylinders 232 are also provided, distributed along the diagonal of the suction cup mounting frame 224. This improves the uniformity of force during vibration, enhances the vibration effect, and minimizes the deformation caused by vibration to the steel sheet 500.

[0066] In the corresponding mold steel sheet 500 implantation anti-overlap deformation method, at the vibration position, the vibration device 230 vibrates the steel sheet 500 picked up by the suction cup 223 up and down, including the following steps: After the loading robot 220 moves to the vibration position, it sends a position arrival signal to the control system. After receiving the position arrival signal, the control system outputs an opening and closing signal to the high-speed air solenoid valve. After receiving the opening and closing signal, the high-speed air solenoid valve performs high-speed valve switching to control the vibration cylinder 232 to drive the vibration rod 231 to move up and down, thereby realizing the vibration of the steel sheet 500. Specifically, after the steel sheet 500 is picked up by the loading robot, it will be raised to the vibration position. Then, after the high-speed air solenoid valve receives the opening and closing signal, it performs high-speed valve switching, thereby controlling the cylinder to move up and down quickly, which in turn drives the vibration rod 231 connected to the cylinder to move up and down quickly, thereby shaking off the overlapping steel sheets 500.

[0067] Furthermore, such as Figure 1 and Figure 2 As shown, in this embodiment, the monitoring mechanism further includes a third detection element 420, which is mounted on the frame 100 and located beside the loading rack 210. The detection range of the third detection element 420 includes the material picking position 211, and the third detection element 420 is connected to the control system. Specifically, the frame 100 includes a vertical frame 110 with a first slide rail 221 installed. The third detection element 420 is mounted on the vertical frame 110 and located below the first slide rail 221, with its height basically flush with the top of the loading rack 210. This allows for better detection of whether a steel sheet 500 exists at the material picking position 211.

[0068] In the corresponding method for preventing overlapping deformation of the mold steel sheet 500, the following steps are included before the loading robot 220 moves to the picking position 211: First, the third detection element 420 detects whether the picking position 211 contains the steel sheet 500; if the third detection element 420 detects that the picking position 211 does not contain the steel sheet 500, the third detection element 420 sends a loading signal to the control system, and the control system outputs a lifting signal to the loading rack 210 according to the loading signal, and the loading rack 210 is driven to lift the steel sheet 500 to the picking position 211; the third detection element 420 checks again whether the picking position 211 contains the steel sheet 500. If the third detection element 420 detects that the picking position 211 contains the steel sheet 500, the third detection element 420 sends a picking signal to the control system, and the control system controls the loading robot 220 to move to the picking position 211 according to the picking signal. Here, the third detection element 420 can be, but is not limited to, fiber optic detection, mainly used to detect whether there is a steel sheet 500 at the material picking position 211, and then transmit the corresponding signal to the control system. If there is no steel sheet 500 at the material picking position 211, the loading rack 210 will lift the steel sheet 500 to the material picking position 211, and then the third detection element 420 will detect again. At this time, if there is a steel sheet 500 at the material picking position 211, the loading robot 220 will run to the material picking position 211 and pick up the steel sheet 500; if the material picking position 211 detects a steel sheet 500, the loading robot 220 will run normally until the material picking position picks up the steel sheet 500. In addition, in this device, there are multiple loading racks 210, which can greatly increase the storage capacity of this device.

[0069] To achieve intelligent control and automatic operation, the control system includes a microprocessor module, a USB-to-serial bus module, a signal input / output module, a signal processing module, a detection and indication module, and a power supply module. These modules are all connected to the microprocessor module. The feeding mechanism 200 also includes a feeding control module for controlling the operation of the feeding rack 210, the feeding robot 220, and the vibration device 230. The injection molding machine with the mold installed includes an injection molding control module. The second detection component includes a camera monitoring microprocessor module. The signal input / output module is connected to the injection molding control module, and the USB-to-serial bus module is connected to the feeding control module. The camera monitoring microprocessor module is connected to the USB-to-serial bus module, the signal processing module, and the detection and indication module. The signal processing module is connected to the signal input / output module, which includes multiple I / O interfaces.

[0070] Specifically, in this embodiment, the feeding control module may be, but is not limited to, the main control computer of the feeding mechanism 200, and the injection molding control module may be, but is not limited to, the main control computer of the injection molding machine. The microprocessor module is mainly used to control the operation of the entire circuit, and the power supply module mainly provides electrical energy. During the control process of the feeding mechanism 200, the microprocessor first sends relevant detection commands to the third detection element 420, then the third detection element 420 performs detection and transmits the detection information to the signal processing module through the USB to serial bus module. Then, the microprocessor module controls the signal processing module to transmit the converted detection information to the detection indication module for judgment, and issues corresponding control commands based on the judgment results. These control commands are transmitted to the feeding control module through the USB to serial bus module, and the feeding control module then controls whether the feeding rack 210 lifts the steel sheet 500 or controls the operation of the feeding robot 220, etc., according to the control commands. During the inspection of the steel sheet 500 in the positioning fixture 300, the microprocessor module issues relevant inspection commands based on relevant signals and transmits them to the first inspection element 410. The first inspection element 410 performs thickness inspection on the steel sheet 500 in the positioning groove 310 and transmits the inspection information to the signal processing module via the USB to serial bus module. Then, the microprocessor module controls the signal processing module to transmit the converted inspection information to the inspection indication module for judgment and issues corresponding control commands based on the judgment result. If the judgment result is unqualified, the feeding control module will control the feeding robot 220 to stop according to the received stop command, and the alarm module will sound an alarm. During the camera monitoring process inside the mold, the camera monitoring microprocessor module controls the second detection component to capture images of the steel sheet 500 implanted in the cavity. The captured image information is then transmitted to the signal processing module via a USB-to-serial bus module. The microprocessor module then controls the signal processing module to transmit the converted information to the detection indication module for judgment, and issues corresponding control commands based on the judgment results. Here, the injection control module of the injection molding machine is connected to the information processing module via a signal input / output module. If the detection fails, the injection control module receives a corresponding stop command, preventing the mold from closing. Simultaneously, the feeding control module also receives a corresponding stop command, stopping the feeding robot 220. Of course, corresponding control commands are also sent to the alarm module to trigger an alarm.

[0071] Please see Figure 1 , Figure 3 and Figure 4, in this embodiment, the positioning fixture 300 is disposed beside the loading rack 210, and a clamping position 320 is provided in the positioning groove 310; the detection probe of the first detection member 410 is exposed on the side wall of the positioning groove 310. Here, the first detection member 410 can be, but is not limited to, a fiber optic sensing detection method. A detection hole is formed on the side wall of the positioning fixture 300, and the detection probe is located in the detection hole. The first detection member 410 is connected to relevant components of the control system through a cable to achieve the transmission of detection signals.

[0072] In the method for implanting the anti-overlap deformation in the corresponding die steel sheet 500, the first detection member 410 detecting whether there is overlap and deformation of the steel sheet 500 in the positioning groove 310 includes the following sub-steps: the first detection member 410 detects the thickness of the steel sheet 500 located in the positioning groove 310, obtains the steel sheet 500 thickness detection value and transmits it to the control system; the control system compares the obtained steel sheet 500 thickness detection value with the pre-stored steel sheet 500 thickness standard value. If the steel sheet 500 thickness detection value is greater than the steel sheet 500 thickness standard value, it is determined as unqualified. The first detection member 410 simultaneously detects whether there is a situation where the clamping position of the steel sheet 500 at the clamping position 320 is deformed and cannot be placed in place; if there is a situation where the clamping position of the steel sheet 500 is deformed and cannot be placed in place, the control system determines it as unqualified. If it is determined as unqualified, the control system outputs a stop signal to the loading manipulator 220, and the loading manipulator 220 stops running after receiving the stop signal; meanwhile, the control system outputs an alarm signal to the alarm module, and the alarm module gives an alarm after receiving the alarm signal. If it is determined as qualified, the control system controls the output of a continue signal to the loading manipulator 220, and the loading manipulator 220 continues to run. Here, the first detection member 410 detects whether the thickness of the steel sheet 500 meets the standard, that is, uses the height difference principle between a single steel sheet 500 and an overlapping steel sheet 500 to detect whether there is overlap. If it is detected that the steel sheet 500 has overlap or the clamping position is deformed and cannot be placed in place, it will be determined as unqualified. At this time, an alarm will be given simultaneously and the loading manipulator 220 will be controlled to stop running. The alarm module can be, but is not limited to, a buzzer or a warning light, etc. Then, the equipment operator will remove the unqualified steel sheet 500 according to the alarm situation, then restart the loading process, and then perform the above detection again.

[0073] Furthermore, after the first inspection piece 410 passes inspection, the loading robot 220 will implant the steel sheet 500 into the mold. The second inspection piece monitors the steel sheet 500 for overlap and deformation within the mold via video, including the following steps: First, the second inspection piece acquires an image of the steel sheet 500 located in the cavity to form a steel sheet 500 implantation inspection image; the steel sheet 500 implantation inspection image is transmitted to the control system. Then, the control system compares the steel sheet 500 implantation inspection image with a pre-stored steel sheet 500 implantation standard image. If the steel sheet 500 implantation inspection image is inconsistent with the steel sheet 500 implantation standard image, the control system determines that the steel sheet 500 implantation is unqualified and outputs a stop signal and a synchronous alarm. The loading robot 220 and the injection molding machine stop operating upon receiving the stop signal; simultaneously, the abnormal position is automatically circled on the steel sheet 500 implantation inspection image; if the steel sheet 500 implantation inspection image is inconsistent with the steel sheet 500 implantation standard image... Figure 1 If the steel sheet 500 is successfully implanted, the control system determines that the implantation is qualified and outputs a mold closing signal. Upon receiving the mold closing signal, the injection molding machine closes the mold and begins injection molding. In other words, in this embodiment, after the steel sheet 500 is implanted into the mold, the second detection component synchronously monitors the steel sheet 500 inside the cavity by capturing images and compares the steel sheet 500 implantation detection image with a pre-stored standard steel sheet 500 implantation image. If a discrepancy is found, it is determined to be unqualified, and a stop signal is immediately output. The loading robot 220 and the injection molding machine immediately stop operating, and the mold cannot be closed. Simultaneously, synchronous alarms and automatic identification of abnormal locations can be implemented to facilitate subsequent handling by staff. This setting, which prohibits mold closing if the inspection fails, absolutely eliminates the risk of mold damage caused by the overlapping and deformation of the steel sheet 500, and also ensures that the equipment does not damage the product during use, thereby ensuring product quality and production efficiency, and saving mold maintenance and usage costs.
