[0031] As shown in Figures 1 to 4 The utility model discloses an integrated screen and rear camera lens pressing equipment, including frame 1, and set up on frame 1's upper die 2, lower die 5, lower pressure cylinder 3, upper top cylinder 4 and template 6, upper die 2 and lower die 5 are arranged oppositely, template 6 is located between upper die 2 and lower die 5, template 6 is equipped with mould cavity 61, the component 200 of being bonded is placed in mould cavity 61, by lower pressure cylinder 3 to upper die 2 applies the lower pressure force, to make screen 100 press to the component 200 of being bonded, by upper top cylinder 4 to lower die 5 applies the upper top force, to make rear camera lens 300 press to the component 200 of being bonded.

[0032] The component 200 of being bonded can be cell phone middle frame or tablet back plate, when pressing, screen 100 and rear camera lens 300 are bonded to the corresponding parts of cell phone middle frame or tablet back plate by double-sided adhesive.

[0033] When working, lower pressure cylinder 3 applies the lower pressure force to upper die 2, lower pressure cylinder 3 drives upper die 2 to move downward, and upper die 2 generates pressure on screen 100, so that screen 100 is tightly pressed to the corresponding position of the component 200 of being bonded by double-sided adhesive, when screen 100 is pressed, upper top cylinder 4 applies the upper top force to lower die 5, and upper top cylinder 4 drives lower die 5 to move upward, and lower die 5 lifts rear camera lens 300 and presses rear camera lens 300 to the corresponding position of the component 200 of being bonded.

[0034] The screen 100 and the rear camera lens 300 are integrated on the same equipment and are pressed, which greatly improves production efficiency. Compared with the traditional pressing by using two equipment respectively, the equipment floor space is reduced. Meanwhile, the number of product transmission between different equipment is reduced, and the operation time is at least shortened, and the quality risk caused by collision, displacement and the like in the transmission process is significantly reduced.

[0035] In an embodiment, as shown in Figure 4 The cavity bottom of the mould cavity 61 is provided with a window 611 corresponding to the position of the rear camera lens 300, and the rear camera lens 300 is pressed to the component 200 of being bonded through the window 611.

[0036] The cavity bottom corresponds to the position of the rear camera lens 300 to open a window 611, so the design is to realize the key structure of the accurate pressing of the rear camera lens 300, so that in the pressing process, the rear camera lens 300 will not be blocked to cause the pressing interference.

[0037] When the attached component 200 is placed in the mold cavity 61, the mounting position of the rear camera lens 300 corresponds to the window 611 at the bottom of the mold cavity 61. The rear camera lens 300 is placed on the lower die 5 below the window 611 in advance, and when the pressing operation is performed, the upper top cylinder 4 drives the lower die 5 to move upward, and the lower die 5 lifts the rear camera lens 300 upward through the window 611 until the rear camera lens 300 is tightly attached to the corresponding position of the attached component 200, and the pressing process is completed.

[0038] In an embodiment, as shown in Figure 4 The integrated screen and rear camera lens pressing device further comprises a position verification plate 7, which is provided with a contoured through slot 71 corresponding to the contour of the rear camera lens 300 along its thickness direction. After the position verification plate 7 is placed in the mold cavity 61, the lower die 5 adjusts its position based on the position of the contoured through slot 71.

[0039] Before the device is ready for pressing operation, the device needs to be debugged and calibrated. At this time, the position verification plate 7 is placed in the mold cavity 61, and the lower die 5 needs to adjust its position according to the position of the contoured through slot 71, so that the part of the lower die 5 used to lift the rear camera lens 300 is accurately aligned with the center position of the contoured through slot 71.

[0040] By setting the position verification plate 7, the pressing position accuracy of the rear camera lens 300 can be controlled at a high level, greatly improving the assembly quality of the product and reducing the incidence of problems such as poor camera shooting effect and light leakage caused by inaccurate lens mounting position.

[0041] In an embodiment, as shown in Figure 4 The lower die 5 comprises a pressing block 51, and the upper surface of the pressing block 51 is provided with a contoured protrusion 511 corresponding to the contour of the rear camera lens 300.

[0042] During production, when the rear camera lens 300 is placed on the contoured protrusion 511, the contoured protrusion 511 provides support for the rear camera lens 300 and facilitates uniform force on the rear camera lens 300, avoiding the problem of insufficient pressing accuracy caused by uneven force on the rear camera lens 300.

[0043] In an embodiment, the upper die 2 comprises a pressing plate 21, and the lower surface of the pressing plate 21 is flat. In this way, uniform and stable pressure can be applied to the screen 100 during the pressing process, effectively avoiding screen damage, poor adhesion, and other problems caused by excessive or insufficient local pressure.

[0044] In an embodiment, the integrated screen and rear camera lens pressing device further comprises a first air pressure adjusting valve 11 and a second air pressure adjusting valve 17. The first air pressure adjusting valve 11 is used to adjust the air pressure of the lower pressing cylinder 3, and the second air pressure adjusting valve 17 is used to adjust the air pressure of the upper pressing cylinder 4.

[0045] Specifically, the first air pressure adjusting valve 11 is responsible for adjusting the air pressure of the lower pressing cylinder 3, and the second air pressure adjusting valve 17 is responsible for adjusting the air pressure of the upper pressing cylinder 4. The first air pressure adjusting valve 11 and the second air pressure adjusting valve 17 are adjusted to the required air pressure according to actual needs. To facilitate operation, the first air pressure adjusting valve 11 and the second air pressure adjusting valve 17 are arranged on the left and right sides of the rack 1, respectively, and the adjusting parts of the first air pressure adjusting valve 11 and the second air pressure adjusting valve 17 are exposed to the outside of the rack 1.

[0046] In an embodiment, as shown in Figure 1 and Figure 2 The integrated screen and rear camera lens pressing device further comprises a touch screen 14, a buzzer 12, an emergency stop button 13, a start button 15, and a safety grating 16.

[0047] The touch screen 14 at least has the functions of setting the pressing time of the lower pressing cylinder 3 and the upper pressing cylinder 4 and setting the delay time of the upper pressing cylinder 4. The touch screen 14 is arranged on the front of the rack 1, which is convenient for the operator to interact. The operator sets the pressing time and the delay time by clicking the touch screen 14. Of course, the touch screen 14 can also be configured to display the running state of the device in real time, such as the current air pressure, temperature, and other parameters, which is convenient for the operator to monitor the running state of the device and discover potential problems in time.

[0048] The buzzer 12 is arranged on the front of the rack 1 and connected to the control circuit through wires. When the device has abnormal conditions, such as low air pressure, high temperature, or device running overtime, the control circuit sends a signal to the buzzer 12, which emits a loud alarm sound.

[0049] The emergency stop button 13 is arranged on the front of the rack 1, and the button is usually red and mushroom-shaped, which is easy to identify and operate. During the operation of the device, if an emergency occurs, such as sudden and severe abnormal vibration of the device, the operator can quickly press the emergency stop button 13 to make the device stop working immediately, avoiding more serious safety accidents or device damage.

[0050] The start button 15 is arranged on the front of the frame 1, generally green. The operator presses the start button 15 after completing all parameter settings and confirming the safety of the equipment and the surrounding environment, and the equipment starts to run according to the preset program.

[0051] The safety grating 16 is installed at the entrance of the working area of the equipment, which is composed of a transmitter and a receiver, which are installed on both sides of the working area respectively. The transmitter emits multiple beams of infrared light, and the receiver receives these light beams. When the safety grating 16 does not detect any object (such as the operator's arm) blocking any of the light beams, the pressing operation is performed, thereby ensuring the safety of the operator.

[0052] In an embodiment, the integrated screen and rear camera lens pressing equipment further comprises a down-pressing in-position sensor, an up-lifting in-position sensor, and an in-position sensor. The down-pressing in-position sensor is used to detect whether the down-pressing cylinder 3 is down-pressed to the position, the up-lifting in-position sensor is used to detect whether the up-lifting cylinder 4 is up-lifted to the position, and the in-position sensor is used to detect whether the component to be attached 200 is placed to the position.

[0053] The down-pressing in-position sensor is installed in the equipment near the end of the stroke of the down-pressing cylinder 3. The down-pressing in-position sensor can be an inductive proximity switch. When the equipment starts, the down-pressing cylinder 3 drives the upper die 2 to move downward for pressing the screen 100. As the piston rod of the down-pressing cylinder 3 moves downward, the metal sensing sheet at the front end of the piston rod gradually approaches the down-pressing in-position sensor. Since the inductive proximity switch uses electromagnetic induction principle, when the metal sensing sheet enters the sensing area of the sensor, the electromagnetic field inside the sensor changes, triggering the circuit to generate an electrical signal change and transmitting it to the control system.

[0054] The up-lifting in-position sensor is installed near the top end of the stroke path of the up-lifting cylinder 4, and is fixed on the equipment frame in a similar manner to the installation of the down-pressing in-position sensor. The common up-lifting in-position sensor can also be an inductive proximity switch. When pressing the rear camera lens 300, the up-lifting cylinder 4 drives the lower die 5 to move upward. The profiling bump 511 on the lower die 5 for lifting the rear camera lens 300 has a metal sensing sheet, and when the component moves upward with the up-lifting cylinder 4 to the sensing area of the up-lifting in-position sensor, the electromagnetic field inside the sensor changes, generating an electrical signal change and transmitting it to the control system.

[0055] The in-position sensor is installed near the mold cavity 61 for detecting whether the component to be attached 200 is correctly placed to the position. The in-position sensor can be an optical sensor, and its emitting end and receiving end are respectively installed at opposite positions on both sides of the mold cavity 61. When the component to be attached 200 is correctly placed in the mold cavity 61, it will block the light emitted by the emitting end of the optical sensor, and the receiving end cannot receive the light, thereby generating an electrical signal change and transmitting the signal to the control system.

[0056] The working process of the integrated screen and rear camera lens pressing device is as follows:

[0057] The operator connects the device to 220V power supply and air pressure, turns on the power switch to provide power for the device operation. According to the physical product to be processed, replace the pressing upper die 2 and lower die 5 matched with it. Then, use the position verification plate 7 (machine mold) made according to the 3D appearance of the product to accurately adjust the pressing position of the upper die 2 and the lower die 5, ensuring the accuracy of the mold position and laying a foundation for subsequent pressing operation. Through the left and right air pressure adjusting valves on the device, the air pressure of the upper and lower air cylinders is adjusted respectively. According to the product requirements, the air pressure is adjusted to a reasonable value to meet the pressure requirements of different pressing stages. On the touch screen 14 of the device, the pressing time of the upper and lower air cylinders and the delay time of the lower air cylinder are set respectively.

[0058] The product to be pressed, i.e. the bonded component 200 containing the screen 100 and the rear camera lens 300 installation position of the mobile phone middle frame or tablet back plate, is carefully placed into the mold cavity 61 of the device. At this time, the in-place sensor detects whether the product is placed in place. If the product is placed correctly, the device enters the next working process; if it is not placed in place, the device will prompt the operator to reposition the product. After the device confirms that the product is placed in place and the safety grating 16 detects no obstacles (such as human arms), the program controls the lower pressing cylinder 3 to drive the upper die 2 to press down towards the screen 100. During the pressing process, the lower pressing in-place sensor monitors the position of the lower pressing cylinder 3 in real time. When it is detected that the upper die 2 has completely pressed the screen 100 to the set position, a feedback signal is immediately sent to the control system, and the pressing time starts at this time. After the screen 100 pressing time starts, after a delay of the lower air cylinder delay time set by the operator on the touch screen 14, the upper lifting cylinder 4 starts to act. The upper lifting cylinder 4 drives the lower die 5 to rise up, and the profiling lug 511 on the lower die 5 lifts the rear camera lens 300, so that it gradually approaches the installation position on the bonded component 200. The upper lifting cylinder 4 continuously pushes the lower die 5 to rise, and the upper lifting in-place sensor monitors the position of the upper lifting cylinder 4 in real time. When it is detected that the lower die 5 has lifted the rear camera lens 300 to the correct position, and the upper lifting in-place sensor sends a feedback signal to the control system, the rear camera lens 300 enters the normal pressing and holding stage. In this stage, the lower die 5 maintains the pressure on the lens, and the duration is the upper lifting cylinder pressing time set on the touch screen 14.

[0059] When the pressing time of the rear camera lens 300 ends, the upper lifting cylinder 4 drives the lower die 5 to retract to the initial position. Then, the lower pressing cylinder 3 drives the upper die 2 to lift and retract, completing a complete screen 100 and rear camera lens 300 pressing operation.

[0060] The above merely describes a specific implementation of the present application, but the protection scope of the present application is not limited thereto, and any skilled person in the art can easily think of various equivalent modifications or replacements within the technical scope disclosed by the present application, and these modifications or replacements should be encompassed within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
