Description

Technical Field

[0001] This invention relates to the field of full inspection technology for mobile phone components, specifically an integrated process for full inspection screening and laser marking of mobile phones. Background Technology

[0002] Due to unavoidable processing defects, multi-parameter product verification, and diverse customer requirements during mobile phone production, the application of full inspection and laser marking for mobile phones is widespread in the market. Currently, traditional full inspection and laser marking for mobile phones is a manual, single-process, multi-station operation. This method of full inspection and laser marking for mobile phones is inefficient, labor-intensive, increases production costs, and is not conducive to continuous production flow. Summary of the Invention

[0003] In order to overcome the defects in the prior art, the purpose of this invention is to provide an integrated process for full inspection and screening of mobile phones and laser marking, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides an integrated process for full inspection and screening of mobile phones and laser marking, comprising the following steps:

[0005] S1. First, put a material tray onto the base box, and then stack several mobile phone parts inside.

[0006] S2. Next, another tray is placed on top of the tray in S1, and several mobile phone parts are stacked on it:

[0007] S3. Then, the computer-controlled servo drive group drives the picking cylinder to move above the material tray, and the picking cylinder drives the suction cup to move down to pick up a mobile phone component, which is then brought to the transplanting production line to be continuously conveyed and fed.

[0008] S4. The mobile phone components being transported pass under the CCD full inspection and screening machine, where they are inspected and transmitted to the computer for comparison with predetermined standards. The computer then analyzes and classifies the components into Class I and Class II, and sends the signals to the laser engraving and marking equipment.

[0009] S5. Then it is transported to the laser marking device under the laser marking component. According to the signal given by the CCD full inspection and screening machine, the corresponding content is marked. After completion, the serial signal is sent to the feeding servo module on the automatic receiving component.

[0010] S6. The picking cylinder in S5, controlled by a computer, picks up the marked mobile phone parts and places them in the receiving bin for sorting and stacking. When the stack reaches the set value, an alarm is triggered to prompt that the parts be picked up.

[0011] As a further improvement to this technical solution, it also includes an automatic feeding component at the head, a CCD full inspection and screening component and a laser engraving and marking component at the middle, and an automatic receiving component at the tail. On one side of the automatic feeding component and below the CCD full inspection and screening component and the laser engraving and marking component, there is a transplanting production line with different widths. The transplanting production line consists of a conveyor belt and a conveyor motor.

[0012] As a further improvement to this technical solution, the automatic feeding component includes a base box, several material trays stacked on top of the middle of the base box, and a feeding servo module for picking up materials to the transplanting production line. The CCD full inspection and screening component includes a CCD full inspection and screening machine and a computer. The laser engraving and marking component includes a laser engraving and marking device and a computer. The automatic receiving component includes at least two receiving bins and a feeding servo module set thereon.

[0013] As a further improvement to this technical solution, the feeding servo module includes a picking cylinder that moves laterally above the transfer production line, a servo transmission group for driving the picking cylinder to move, and a computer for controlling the start of the servo transmission group and the picking cylinder to pick up materials.

[0014] As a further improvement to this technical solution, the feeding servo module is located above the base box, the bottom end of the piston rod of the picking cylinder is connected to a suction cup, and an air compressor for supplying airflow to the picking cylinder is placed on one side of the base box.

[0015] As a further improvement to this technical solution, the top surface of the material tray is provided with several limiting holes, and the limiting holes are distributed in several rectangular closed areas and arranged in a circular array on the material tray. The top surface of the base box is welded with several material dropping rods that are inserted into the limiting holes. A feeding electric cylinder for driving the material tray to move upward and supply material is provided at a corner of the top surface of the base box.

[0016] As a further improvement to this technical solution, a support rod is welded on the central shaft of the bottom surface of the material tray, and a sleeve hole is opened in the center of the bottom surface of the support rod. A material support component that fits into the sleeve hole is welded below the output shaft of the feeding electric cylinder, and a sleeve post that fits into the sleeve hole is welded on the central shaft of the top surface of the material tray.

[0017] As a further improvement to this technical solution, the following steps are included:

[0018] S31. After the topmost mobile phone component is removed, start the feeding electric cylinder to drive several feeding trays to rise synchronously by the thickness of one mobile phone component.

[0019] S32. After all the mobile phone parts on the upper tray have been removed, remove the tray and insert the support column under the tray at the bottom.

[0020] S33. Activating the feeding electric cylinder will drive the support column to support the remaining material tray and continue feeding.

[0021] As a further improvement to this technical solution, a cylinder liner frame is fixedly connected to the top surface of the base box by bolts, and the feeding electric cylinder liner is located inside the cylinder liner frame.

[0022] As a further improvement to this technical solution, a positioning plate group is suspended on the conveyor belt in the transplanting production line, and the positioning plate group consists of a pair of positioning plates arranged symmetrically.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] 1. This integrated process for full inspection and laser marking of mobile phones combines a CCD full inspection screening machine and a laser marking equipment station. Products are manually placed onto several trays of an automatic feeder. After the feeding servo module is activated, the automatic feeder continuously supplies materials to the transfer production line. After positioning and guidance, the CCD full inspection screening machine screens the products, and a centralized serial signal is sent to the laser marking equipment. The products are then transported to the laser marking equipment via the transfer production line. Based on the signals from the CCD full inspection screening, corresponding markings are applied. After marking, a serial signal is sent to the automatic receiving component. The automatic receiving component receives the materials and collects them into the corresponding receiving bin based on the signals from the laser marking equipment's feeding servo module. Under the same conditions, this process significantly improves production efficiency compared to traditional manual multi-station processing, greatly saving manpower, ensuring product quality, and reducing manufacturing costs.

[0025] 2. This integrated process for full inspection and laser marking of mobile phones utilizes several material trays. After the top layer of mobile phone components is removed, the feeding electric cylinder is activated to drive several material trays to rise synchronously by the thickness of one mobile phone component. This process continues until all mobile phone components on the upper material tray are removed. Then, the material tray is removed, and the support column is inserted under the bottom material tray. The feeding electric cylinder is then activated again to drive the support column to support the remaining material trays and continue feeding. This process provides a longer and more stable feeding continuity and has value for widespread application. Attached Figure Description

[0044] Please see Figures 1-8 As shown, this invention provides an integrated process for full inspection and laser marking of mobile phones, including the following steps:

[0045] S1. First, put a material tray 110 onto the base box 140, and then stack several mobile phone parts.

[0046] S2, Next, another tray 110 is placed on top of the tray 110 in S1, and several mobile phone parts are stacked on it:

[0047] S3. Then, the servo transmission group 520 is started by computer control to drive the picking cylinder 510 to move above the material tray 110, and the picking cylinder 510 drives the suction cup to move down to pick up a mobile phone component, and then bring it to the transplanting production line 210 to be continuously conveyed and fed.

[0048] S31. After the top layer of mobile phone components is removed, the feeding cylinder 130 is activated to drive several feeding trays 110 to rise synchronously by the thickness of one mobile phone component.

[0049] S32. After all the mobile phone parts on the upper tray 110 have been removed, remove the tray 110 and insert the support column under the tray 110 at the bottom.

[0050] S33, starting the feeding electric cylinder 130 will drive the support column to support the remaining material tray 110 to continue feeding;

[0051] S4. The mobile phone components being transported pass under the CCD full inspection and screening machine, where they are inspected and transmitted to the computer for comparison with predetermined standards. The computer then analyzes and classifies the components into Class I and Class II, and sends the signals to the laser engraving and marking equipment.

[0052] S5. Then it is transported to the laser marking device under the laser marking component 300. According to the signal given by the CCD full inspection and screening machine, the corresponding content is marked. After completion, the serial signal is sent to the feeding servo module 500 on the automatic receiving component 400.

[0053] S6. The picking cylinder 510 in S5, controlled by a computer, picks up the marked mobile phone parts and places them on the receiving bin 410 for sorting and stacking. When the stack reaches the set value, an alarm is triggered to prompt that the parts be picked up.

[0054] Specifically, it also includes an automatic feeding component 100 at the head, a CCD full inspection and screening component 200 and a laser marking component 300 at the middle, and an automatic receiving component 400 at the tail. A transfer production line 210 of different widths is provided on one side of the automatic feeding component 100 and below the CCD full inspection and screening component 200 and the laser marking component 300. The transfer production line 210 consists of a conveyor belt and a conveyor motor. The CCD full inspection and screening component 200 and the laser marking component 300 are existing technologies and will not be described in detail here.

[0055] The automatic feeding component 100 includes a base box 140, several material trays 110 stacked on top of the middle of the base box 140, and a feeding servo module 500 for picking up materials and transferring them to the transplanting production line 210. The CCD full inspection and screening component 200 includes a CCD full inspection and screening machine and a computer. The laser engraving and marking component 300 includes a laser engraving and marking device and a computer. The automatic receiving component 400 includes at least two receiving bins 410 and a feeding servo module 500 set thereon.

[0056] By combining a full inspection screening machine and a laser marking device, products are manually placed onto the material tray 110 of the automatic feeding component 100 in a concentrated manner, while continuously feeding the conveyor belt of the transfer production line 210. After being screened by the CCD full inspection screening machine, the signal is sent to the laser marking device for marking. After completion, the signal is sent to the feeding servo module 500 on the automatic receiving component 400, and then the product is received into the corresponding receiving bin 410 according to the signal given by the laser marking device.

[0057] Furthermore, a positioning plate assembly 220 is suspended on the conveyor belt in the transplanting production line 210. The positioning plate assembly 220 consists of a pair of symmetrically arranged positioning plates, which are used to position and guide the mobile phone parts to be accurately transported by the conveyor belt to the working range directly below the CCD full inspection screening machine and the laser engraving marking equipment.

[0058] Furthermore, a pusher plate 420 is provided at the inner end of the receiving bin 410, and several pusher cylinders connected to the pusher plate 420 are provided in the top of the automatic receiving component 400. The piston rod of the pusher cylinder is welded to the pusher plate 420 to control the pusher plate 420 to move within the receiving bin 410, thereby pushing the mobile phone parts stacked to the set value forward by one body position so that the picking cylinder 510 can continue to adsorb the marked mobile phone parts for stacking and storage.

[0059] In addition, the feeding servo module 500 includes a picking cylinder 510 that moves horizontally above the transfer production line 210, a servo transmission group 520 for driving the picking cylinder 510 to move, and a computer for controlling the start of the servo transmission group 520 and the picking cylinder 510 to pick up materials. An electric cylinder is installed above the picking cylinder 510. The servo transmission group 520 is composed of a servo motor, a lead screw, and a threaded sleeve. The output shaft of the servo motor is coaxially connected to the lead screw, the threaded sleeve is threadedly connected to the lead screw, and the threaded sleeve is fixedly connected to the electric cylinder by bolts, thus forming a lead screw transmission method. This is existing technology and will not be described in detail here.

[0060] The loading servo module 500 is located above the base box 140. The bottom end of the piston rod of the picking cylinder 510 is connected to a suction cup. An air compressor that delivers airflow to the picking cylinder 510 is placed on one side of the base box 140. The picking cylinder 510 is driven to rise and fall by an electric cylinder so that the suction cup contacts the mobile phone component. Then, the picking cylinder 510 draws air from the suction cup to allow it to adsorb the mobile phone component. When the mobile phone component is placed down, the picking cylinder 510 inflates the suction cup to release the mobile phone component.

[0061] It is worth noting that the top surface of the material tray 110 is provided with several limiting holes 111, and the several limiting holes 111 are distributed into several rectangular closed areas and arranged in a circular array on the material tray 110 for continuously feeding several mobile phone parts.

[0062] The top surface of the base box 140 is welded with several material dropping rods 120 that are inserted into several limiting holes 111. A material feeding electric cylinder 130 is provided at a corner of the top surface of the base box 140 to drive the material feeding tray 110 to move upward and feed material, so that the mobile phone component is raised to the height of the material picking cylinder 510 picking up the material.

[0063] Furthermore, a support rod 112 is welded to the central shaft of the bottom surface of the material tray 110, and a sleeve hole 113 is opened in the center of the bottom surface of the support rod 112. A material support component 131 that fits into the sleeve hole 113 is welded below the output shaft of the feeding electric cylinder 130. A sleeve post 114 that fits into the sleeve hole 113 is welded to the central shaft of the top surface of the material tray 110, making it convenient to stack the material tray 110 and rotate it, thereby turning several mobile phone parts on the remaining rectangular closed area to the area below the material picking range of the picking cylinder 510.

[0064] Before placing the support column under the material tray 110, the feeding electric cylinder 130 needs to be activated to drive the material support component 131 to move down to the bottom of the base box 140 and lift up several material trays 110 above, so that the support column can be inserted into the base box 140.

[0065] A cylinder liner frame 141 is fixedly connected to the top surface of the base box 140 by bolts. The feeding electric cylinder 130 is sleeved in the cylinder liner frame 141 for positioning and protection of the feeding electric cylinder 130.

[0066] It should be noted that the above embodiments are only for illustrating the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand the content of the present invention and implement it accordingly. They should not be used to limit the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
