Description

Technical Field

[0001] This invention relates to the field of auxiliary material application machine technology, and in particular to an auxiliary material application machine and an auxiliary material application method. Background Technology

[0002] In the production of electronic products such as mobile phones and tablets, auxiliary materials need to be applied. Currently available auxiliary material application machines are designed for products of specific sizes and have fixtures that are adapted to the product size. If the product size changes, the fixture needs to be replaced, which not only increases equipment costs but also wastes labor time.

[0003] For products of various sizes that require the application of accessories, the industry currently mainly relies on manual application, which results in low production efficiency and poor consistency. Therefore, there is an urgent need for equipment that can automatically apply accessories to products of various sizes. Summary of the Invention

[0004] In view of this, the present invention provides an accessory applicator, which aims to automatically apply accessories to products of various sizes without changing the fixture during product changeover production.

[0005] To solve the above problems, the present invention provides an auxiliary material applicator, comprising: Auxiliary material supply mechanism, used to provide auxiliary materials; The auxiliary material temporary storage platform is used to receive and temporarily store the auxiliary materials provided by the auxiliary material receiving mechanism, and is also the workstation for taking the first photo of the auxiliary materials; The photo-taking station is the next station after the auxiliary materials are transferred from the auxiliary material storage platform, and it is also the station where the auxiliary materials are photographed for the second time. The auxiliary material application station is located next to the photography station. It is the next station where the auxiliary materials are transferred from the photography station, and it is also the station for positioning the product and taking a third photo of the auxiliary materials. The first camera is used to take pictures of the auxiliary materials on the auxiliary material storage platform to form real-time photos. The second camera is used to take real-time photos of the auxiliary materials at the photo-taking station. The third camera is used to take real-time photos of the auxiliary materials pasted on the products positioned at the auxiliary material pasting station. The auxiliary material transfer mechanism is used to sequentially move to the auxiliary material temporary storage platform to retrieve auxiliary materials, move to the photo taking station to pause, and move to the auxiliary material pasting station to paste auxiliary materials. The control system is connected to the auxiliary material transfer mechanism, the first camera, the second camera, and the third camera via data cables. It stores standard photos of the ideal positions of the auxiliary materials in the auxiliary material temporary storage platform, the photo-taking station, and the auxiliary material application station. The control system receives real-time photos from the first camera, compares them with the standard photos, calculates the deviation, and controls the auxiliary material transfer mechanism to perform correction based on the deviation. The control system also receives real-time photos from the second camera, compares them with the standard photos, calculates the deviation, and controls the auxiliary material transfer mechanism to perform correction based on the deviation. The control system also receives real-time photos from the third camera, compares them with the standard photos, and outputs bonding OK or NG information.

[0006] Optionally, the auxiliary material transfer mechanism includes a material-applying robot and a translation mechanism; the material-applying robot includes a lifting auxiliary material mechanism and a rotating auxiliary material mechanism; the translation mechanism is used to translate the material-applying robot to the auxiliary material temporary storage platform, the photography station, and the material-applying station in sequence; the translation mechanism includes an X-axis driver and a Y-axis driver; the material-applying robot is fixed on the moving part of the X-axis driver; the fixed part of the X-axis driver is fixed on the moving part of the Y-axis driver; and the fixed part of the Y-axis driver is fixed on the frame.

[0007] Optionally, the material-applying robot includes a lifting platform, a material-picking and placing mechanism, and a rotating mechanism, wherein the rotating mechanism is mounted on the lifting platform and is used to drive the material-picking and placing mechanism to rotate.

[0008] Optionally, the rotating mechanism includes a first driver, a turntable, and a rotating shaft. The first driver is fixed to the lifting platform to drive the turntable to rotate. The rotating shaft is coaxial with the turntable, and the material handling mechanism is fixed to the bottom end of the rotating shaft.

[0009] Optionally, there are two turntables and two rotating shafts, and the first driver drives the two turntables to rotate synchronously via a timing pulley.

[0010] Optionally, the liftable platform includes a housing, a Z-axis slide rail, and a second driver. The housing is fixed to the moving part of the X-axis driver. The Z-axis slide rail is provided with a drive block and a slide seat, which are adapted to slide along the Z-axis, from top to bottom. The second driver is used to drive the drive block to slide on the Z-axis slide rail. A buffer structure is connected between the drive block and the slide seat. The slide seat is connected to the rotating shaft. When the drive block moves upward, it lifts the slide seat through the buffer structure to move upward together. When the drive block moves downward, it presses down the buffer structure to make the slide seat move downward.

[0011] Optionally, the buffer structure includes a spring and a limiting post. The limiting post is fixed to the slide and extends along the Y-axis. The driving block is provided with a limiting hole that cooperates with the limiting post. The portion of the limiting post located between the driving block and the slide is fitted with the spring. The top of the limiting post is located outside the limiting hole and is provided with an end cap. The driving block pulls the slide upward together through the end cap. The driving block compresses the spring to make the slide move downward.

[0012] Optionally, an active synchronous pulley and a driven synchronous pulley are provided between the two Z-axis slide rails, and the two synchronous pulleys are connected by a synchronous belt. The second driver is used to drive the active synchronous pulley to rotate, and a drive block is fixed on each side of the synchronous belt.

[0013] Optionally, the bottom end of the housing is connected to the turntable via a first bearing, the slide is connected to the rotating shaft via a second bearing, the side wall of the rotating shaft is provided with an axially extending pin groove, the side of the turntable is provided with a pin hole, and the pin hole is connected to the pin groove via a pin.

[0014] The present invention also provides a method for applying auxiliary materials, which, according to the above-mentioned auxiliary material application machine, includes the following steps: The first step is to position the product in the accessory application station, and then place the accessory on the product at the designated location, ensuring that the position and orientation of the accessory meet the OK application standard. The second step is to activate the third camera to take pictures of the auxiliary materials on the auxiliary material application station and transmit the pictures to the control system for storage as standard pictures. The third step is to set the reverse movement program of the auxiliary material transfer machine according to the original movement path of the auxiliary material transfer mechanism, so that the auxiliary material transfer mechanism moves to the photo taking station after picking up the auxiliary material at the auxiliary material taking station. The second camera takes a picture of the auxiliary material and transmits the picture to the control system as a standard picture for storage. Then it moves to the auxiliary material temporary storage platform, releases the auxiliary material on the auxiliary material temporary storage platform, and takes a picture of the auxiliary material through the first camera and transmits the picture to the control system as a standard picture for storage. The fourth step is to restore the normal working state of the auxiliary material applicator. The auxiliary material feeding mechanism conveys the auxiliary material to the auxiliary material storage platform. The first camera takes a picture of the auxiliary material on the auxiliary material storage platform and transmits the real-time picture to the control system. The control system compares the real-time picture with the standard picture and calculates the X-axis translation deviation, Y-axis translation deviation and rotation deviation. The auxiliary material transfer mechanism descends to pick up the auxiliary material and then rises and stops. The control system controls the auxiliary material transfer mechanism to perform the first correction of the auxiliary material according to the deviation. Fifth step: After the first correction, the auxiliary material transfer mechanism moves the auxiliary material to the photo taking station. The second camera takes a picture of the auxiliary material in the photo taking station and transmits the real-time photo to the control system. The control system compares the real-time photo with the standard photo and calculates the X-axis translation deviation, Y-axis translation deviation and rotation deviation. The control system controls the auxiliary material transfer mechanism to perform the second correction on the auxiliary material according to the deviation. Step 6: After the second correction, the auxiliary material transfer mechanism moves the auxiliary material to the auxiliary material application station and applies the auxiliary material to the product. The third camera takes a picture of the auxiliary material on the product and transmits the real-time photo to the control system. The control system compares the real-time photo with the standard photo, determines whether the application is OK or NG, and outputs the judgment information to the control system. Step 7: When the bonding is deemed OK, the control system controls the auxiliary material transfer mechanism to move to the auxiliary material storage platform to retrieve the auxiliary material for the next round of bonding process; when the bonding is deemed NG, the control system controls the auxiliary material transfer mechanism to remove the bonded auxiliary material from the product and retrieve the material for re-bonding according to the process, or controls the auxiliary material on the auxiliary material transfer mechanism to re-bond. If the re-bonding fails multiple times, the control system will alarm to notify manual intervention.

[0015] The technical solution of the present invention has the following advantages: 1. The first photo and correction eliminates the deviation between the actual position and the standard position of the auxiliary material on the auxiliary material storage platform. The second photo and correction eliminates the deviation between the actual position and the standard position of the auxiliary material when it arrives at the photo station due to mechanical transmission errors, inertia, response delays and other reasons during the long-distance displacement of the auxiliary material from the auxiliary material storage platform to the photo station. The third photo determines the magnitude of the deviation between the actual position of the auxiliary material on the product and the standard position, thereby judging whether the fit is OK or NG.

[0016] 2. When changing product models, there is no need to change the fixture. Simply use the corresponding camera to record the standard position of the auxiliary material at each station. This will correct the real-time positional deviation of the auxiliary material, so that the deviation of the auxiliary material finally attached to the product is as small as possible, thereby meeting the standard of OK material attachment.

[0017] 3. This equipment enables the bonding of various auxiliary materials on the back cover of mobile phones made of glass and composite board materials, completely replacing manual labor, greatly increasing production capacity and saving labor costs. Attached Figure Description

[0033] Please refer to Figure 1 and Figure 2 This invention provides an auxiliary material applicator, which includes a frame. On the frame, from far to near the conveyor line 10 that transports the product 100, an auxiliary material feeding mechanism 1, an auxiliary material temporary storage platform 2, a photo taking station 3, and an auxiliary material applicator 4 are arranged in sequence. The auxiliary material receiving mechanism 1 is used to provide auxiliary material 200. Since the auxiliary material 200 is a roll of material densely arrayed and pasted on release paper, an unwind feeder is used to peel it off. The unwound material strip 300 passes through the auxiliary material temporary storage platform 2. The auxiliary material temporary storage platform 2 is used to temporarily store and stabilize the auxiliary material 200 provided by the auxiliary material receiving mechanism 1. The auxiliary material temporary storage platform 2 is also the station for taking the first photo of the auxiliary material 200. The photo taking station 3 is set up next to the auxiliary material pasting station 4. The photo taking station 3 is located between the auxiliary material pasting station 4 and the auxiliary material temporary storage platform 2. The photo taking station 3 is the next station after the auxiliary material 200 from the auxiliary material temporary storage platform 2 is transferred. The photo taking station 3 is the station for taking the second photo of the auxiliary material 200. The auxiliary material pasting station 4 is the next station after the auxiliary material 200 from the photo taking station 3 is transferred. The auxiliary material pasting station 4 is the station for positioning the product 100, receiving the auxiliary material 200 and taking the third photo of the auxiliary material 200.

[0034] Please refer to Figure 3Each photo is taken using a corresponding camera, which converts the optical image into a digital signal. The first photo is taken using a first camera 5, which is located directly above the auxiliary material storage platform 2. The lens of the first camera 5 faces downwards to take a photo of the auxiliary material 200 on the auxiliary material storage platform 2 to form a real-time photo. The second photo is taken using a second camera 6, which is located directly below the auxiliary material 200 that has been transported to the photo taking station 3. The second camera 6 is used to take a photo of the auxiliary material 200 that is stationed at the photo taking station 3 to form a real-time photo. The third photo is taken using a third camera 7, which is located directly above the product 100 positioned at the auxiliary material attaching station 4. The third camera 7 is used to take a photo of the auxiliary material 200 that has been attached to the positioned product 100 at the auxiliary material attaching station 4 to form a real-time photo.

[0035] Please refer to Figure 4 Specifically, the auxiliary material storage platform 2 is a horizontal platform plate, and the material strip 300 is flatly attached to the upper surface of the auxiliary material storage platform 2. A pressing belt roller 12 and a pressing belt plate 13 are provided between the auxiliary material storage platform 2 and the auxiliary material feeding mechanism 1. The pressing belt roller 12 is used to press down the material strip 300 so that the material strip 300 is flatly attached to the upper surface of the auxiliary material storage platform 2. The pressing belt plate 13 includes a fixed plate 131 and a movable plate 132. The movable plate 132 is used to press the material strip 300 onto the fixed plate 131 so that the material strip 300 stops moving forward. The fixed plate 131 is fixed on the frame. A cylinder is provided on the frame to drive the movable plate 132 to intermittently press and separate from the movable plate 132. Below the auxiliary material storage platform 2, there is a winding roller 11 to wind up the material strip 300. Therefore, the material strip 300 can move forward in inching motion according to the rhythm.

[0036] The auxiliary material applicator is equipped with an auxiliary material transfer mechanism for picking up, placing, and transferring auxiliary materials. The auxiliary material transfer mechanism is used to sequentially move to the auxiliary material temporary storage platform 2 to pick up auxiliary materials, move to the photo taking station 3 to pause, and move to the auxiliary material applicator station 4 to apply auxiliary materials. The auxiliary material transfer mechanism includes an applicator robot 8 and a translation mechanism 9.

[0037] Please refer to Figure 2 The material applicator descends to pick up material 200 via the material applicator robot 8, and then rises again. The material applicator moves the material applicator robot 8 via the translation mechanism 9, so that the material applicator robot 8 first reaches the material temporary storage platform 2 to pick up the material 200, then moves to the photo taking station 3 to take a photo, and finally moves to the material applicator station 4 to apply the material and take a photo.

[0038] The translation mechanism 9 includes an X-axis driver 91 and a Y-axis driver 92. The X-axis driver 91 and the Y-axis driver 92 are preferably linear guides driven by servo motors. The housing of the linear guide is the fixed part, and the sliding seat on the linear guide is the moving part. The fixed part of the Y-axis driver 92 is fixed to the frame, and the X-axis driver 91 is fixed to the moving part of the Y-axis driver 92. Specifically, the fixed part of the X-axis driver 91 is fixed to the moving part of the Y-axis driver 92, and the material-applying robot 8 is fixed to the moving part of the X-axis driver 91.

[0039] Please refer to Figure 5 The material-applying robot 8 includes a lifting mechanism 81, a material-picking and placing mechanism 82, and a rotating mechanism 83. The rotating mechanism 83 is mounted on the lifting mechanism 81 and drives the material-picking and placing mechanism 82 to rotate in a plane. The lifting mechanism 81 is fixed to the moving part of the X-axis driver 91. Specifically, the rotating mechanism 83 includes a first driver 831, a turntable 832, and a rotating shaft 833. The first driver 831 is fixed to the housing of the material-applying robot 8 and drives the turntable 832 to rotate. The rotating shaft 833 is coaxial with the turntable 832 and passes through the central hole of the turntable 832. The material-picking and placing mechanism 82 is fixed to the bottom end of the rotating shaft 833. Preferably, there are two turntables 832 and two rotating shafts 833. The first driver 831 drives the two turntables 832 to rotate synchronously via a synchronous pulley. Specifically, the rotating shaft 833 is a hollow air tube, and the material feeding mechanism 82 is a suction cup. The hollow air tube is connected to the suction cup, and the bottom surface of the suction cup has suction holes. The auxiliary material 200 is adsorbed by negative pressure. When the suction cup rises, it peels the auxiliary material 200 off the release paper.

[0040] Please refer to Figure 5 and Figure 6 Furthermore, the lifting mechanism 81 includes a housing 811, a Z-axis slide rail 812, and a second driver 813. The housing 811 is fixed to the moving part of the X-axis driver 91. The Z-axis slide rail 812 is provided with a drive block 814 and a slide seat 815 adapted to slide along the Z-axis from top to bottom. The second driver 813 is used to drive the drive block 814 to slide on the Z-axis slide rail 812. A buffer structure is connected between the drive block 814 and the slide seat 815. The slide seat 815 is connected to the rotating shaft 833.

[0041] When the drive block 814 moves upward, it pulls the slide block 815 upward together through the buffer structure. When the drive block 814 moves downward, it causes the slide block 815 to move downward through the downward buffer structure. Specifically, the buffer structure includes a spring 817 and a limiting post 816. The limiting post 816 is fixed on the slide block 815 and extends along the Z-axis. The drive block 814 is provided with a limiting hole 814a that mates with the limiting post 816 (see...). Figure 6 A spring 817 is sleeved on the part of the limiting post 816 located between the driving block 814 and the slide 815. The top of the limiting post 816 is located outside the limiting hole 814a and is provided with an end cap 816a. The driving block 814 lifts the slide 815 together to move upward through the end cap 816a. The driving block 814 compresses the spring 817 to make the slide 815 move downward.

[0042] Please refer to Figure 5Furthermore, a driving synchronous pulley 818 and a driven synchronous pulley 819 are arranged vertically between the two Z-axis slide rails 812. The two synchronous pulleys are connected by a synchronous belt 810. A second driver 813 is used to drive the driving synchronous pulley 818 to rotate. A drive block 814 is fixed on each side of the synchronous belt 810. The second driver 813 is preferably a servo motor. By driving the synchronous belt 810 to rotate forward and backward, the two picking and placing mechanisms 82 can be controlled to pick up or place materials alternately. That is, the translation mechanism 9 can perform two picking and two placing operations in one conveying operation, which improves work efficiency.

[0043] Please refer to Figure 7 and Figure 8 Specifically, the bottom end of the housing 811 is connected to the turntable 832 via a first bearing 14, and the slide 815 is connected to the rotating shaft 833 via a second bearing 15. The side wall of the rotating shaft 833 is provided with an axially extending pin groove 833a, and the side of the turntable 832 is provided with a pin hole 832a. The pin hole 832a is connected to the pin groove 833a via a pin. Preferably, a synchronous pulley is used directly as the turntable 832; alternatively, other annular objects can be used as the turntable 832, and a fixed synchronous pulley can be fitted over the turntable 832.

[0044] The auxiliary material application machine is also equipped with a control system, which uses either a PLC or a computer. Due to the ease of human-machine interaction, a computer is preferred. The control system connects to the auxiliary material transfer mechanism, the first camera 5, the second camera 6, and the third camera 7 via data cables. It stores standard photos of the ideal positions of the auxiliary materials within the auxiliary material storage platform 2, the photo-taking station 3, and the auxiliary material application station 4. The control system receives real-time photos from the first camera 5, compares them with the standard photos to calculate the deviation, and controls the auxiliary material transfer mechanism to perform correction based on the deviation. The control system also receives real-time photos from the second camera 6, compares them with the standard photos to calculate the deviation, and controls the auxiliary material transfer mechanism to perform correction based on the deviation. Finally, the control system receives real-time photos from the third camera 7, compares them with the standard photos, and outputs "OK" or "NG" information for bonding.

[0045] Furthermore, a pressure sensor can be installed at the end of the spring 817. The pressure sensor is connected to the control system via a data line. The pressure sensor is adapted to send an electrical signal to the control system when the pressure reaches a specified value. The control system is adapted to control the second driver 813 to stop driving when it receives the electrical signal from the pressure sensor. The trigger pressure value of the pressure sensor can be preset according to the pressure that the electronic components on the product can withstand.

[0046] The auxiliary material applicator proposed in this embodiment of the invention first takes a picture of the auxiliary material 200 on the auxiliary material storage platform 2 to determine the deviation of the actual position of the auxiliary material 200 from the standard position of the auxiliary material on the auxiliary material storage platform 2, and then corrects the deviation of the auxiliary material 200 from the standard position on the auxiliary material storage platform 2. Then, a second picture of the auxiliary material 200 is taken at the picture station 3, and the auxiliary material 200 is corrected again to eliminate the deviation of the actual position of the auxiliary material 200 from the standard position when it arrives at the picture station 3 due to mechanical transmission errors, inertia, response delays, etc., during the long-distance displacement of the auxiliary material 200 from the auxiliary material storage platform 2 to the picture station 3. Finally, a third picture of the auxiliary material 200 is taken at the auxiliary material applicator station 4 to determine the deviation of the auxiliary material 200 from the standard position of the auxiliary material on the product 100. If the deviation is less than the standard, the applicator is judged to be OK; if the deviation is greater than the standard, the applicator is judged to be NG.

[0047] Since the photo-taking station 3 is located next to the auxiliary material application station 4, the displacement distance is short, so the deviation caused by mechanical transmission error is small. Therefore, when the auxiliary material 200 is transported from the photo-taking station 3 to the auxiliary material application station 4, the displacement and rotation angle in the X-axis and Y-axis directions are very small. So after the auxiliary material 200 is corrected at the photo-taking station 3, it can be transferred to the auxiliary material application station 4 for direct application without needing to be corrected again at the auxiliary material application station 4 before application.

[0048] Based on the above-mentioned applicator, this invention also proposes an applicator application method, comprising the following steps: The first step is to position the product within the auxiliary material application station 4, and then place the auxiliary material on the product at the designated application location, ensuring that the position and orientation of the auxiliary material meet the OK application standard. The second step is to activate the third camera 7 to take pictures of the auxiliary materials on the auxiliary material application station 4 and transmit the pictures to the control system for storage as standard pictures. The third step is to set the reverse movement program of the auxiliary material transfer mechanism according to the original movement path of the auxiliary material transfer mechanism, so that the auxiliary material transfer mechanism moves to the photo taking station 3 after taking the auxiliary material at the auxiliary material taking station 4. The second camera 6 takes a picture of the auxiliary material and transmits the picture to the control system as a standard picture for storage. Then it moves to the auxiliary material temporary storage platform 2 to release the auxiliary material on the auxiliary material temporary storage platform 2 and takes a picture of the auxiliary material through the first camera 5 and transmits the picture to the control system as a standard picture for storage. The fourth step is to restore the normal working state of the auxiliary material applicator. The auxiliary material feeding mechanism 1 conveys the auxiliary material to the auxiliary material temporary storage platform 2. The first camera 5 takes pictures of the auxiliary material on the auxiliary material temporary storage platform 2 and transmits the real-time photos to the control system. The control system compares the real-time photos with the standard photos and calculates the X-axis translational deviation, Y-axis translational deviation and rotational deviation. The auxiliary material transfer mechanism descends to pick up the auxiliary material and then rises and stops. The control system controls the auxiliary material transfer mechanism to perform the first correction of the auxiliary material according to the deviation. Fifth step: After the first correction, the auxiliary material transfer mechanism moves the auxiliary material to the photo taking station 3. The second camera 6 takes a picture of the auxiliary material in the photo taking station 3 and transmits the real-time picture to the control system. The control system compares the real-time picture with the standard picture and calculates the X-axis translation deviation, Y-axis translation deviation and rotation deviation. The control system controls the auxiliary material transfer mechanism to perform the second correction on the auxiliary material according to the deviation. Step 6: After the second correction, the auxiliary material transfer mechanism moves the auxiliary material to the auxiliary material application station 4, applies the auxiliary material to the product, and the third camera 7 takes a picture of the auxiliary material on the product and transmits the real-time photo to the control system. The control system compares the real-time photo with the standard photo, determines whether the application is OK or NG, and outputs the judgment information to the control system. Step 7: When the bonding is deemed OK, the control system controls the auxiliary material transfer mechanism to move to the auxiliary material storage platform 2 to retrieve the auxiliary material for the next round of bonding process; when the bonding is deemed NG, the control system controls the auxiliary material transfer mechanism to remove the bonded auxiliary material from the product and retrieve the material for re-bonding according to the process, or controls the auxiliary material on the auxiliary material transfer mechanism to re-bond. If the re-bonding fails multiple times, the control system will alarm to notify manual intervention.

[0049] The auxiliary material application machine and its material lifting method proposed in this invention eliminate the need to change fixtures during product changeovers. By simply recording the standard position of the auxiliary material at each workstation using a corresponding camera, real-time positional deviations of the auxiliary material can be corrected, minimizing the deviation of the auxiliary material ultimately applied to the product and meeting the application OK standard.
