Description

Technical Field

[0001] The present invention relates to the technical field of laser welding, and in particular to a metal aluminum alloy camera module laser welding machine. Background Art

[0002] In today's digital age, cameras, as key components for information collection, are widely used in a variety of electronic devices such as smart phones, laptops, and security monitoring systems. The quality of camera modules is directly related to the clarity and stability of image capture, so its manufacturing process, especially the welding technology during the assembly process, is particularly important. At present, the camera housing commonly used in the market is made of metal aluminum alloy. This material is not only light and durable, but also has good thermal conductivity, which can effectively dissipate heat and extend the service life of the camera.

[0003] In the production process of aluminum alloy camera modules, laser welding technology is widely used due to its advantages such as high precision and pollution-free. However, the existing aluminum alloy camera laser welding machines are usually designed with the lower mold connected to the motor, and the upper mold installed on a freely rotating bearing. When working, the operator needs to first accurately align the two halves of the camera housing, and then place it as a whole into the lower mold. Subsequently, the upper mold is moved toward the lower mold through the control system until the upper mold is tightly pressed on the camera housing. Next, the motor drives the lower mold to rotate, driving the entire camera housing and the upper mold to rotate together. At this time, the laser beam is scanned along the predetermined path to achieve efficient welding of the camera housing.

[0004] Although the above method can meet basic welding requirements, there are still several shortcomings in actual operation: First, since the upper mold is only fixed by a freely rotating bearing, the position of the upper mold is prone to shifting when the upper mold applies pressure to the camera housing or when the operator manually removes the welded camera. Once the relative position between the upper mold and the lower mold changes, it will directly affect the accuracy and efficiency of subsequent welding work and may even cause welding failure. Secondly, when the operator manually places the two halves of the camera housing in the lower mold, due to the lack of an effective positioning device, it is difficult to ensure that the camera housing can be placed completely flat every time. The existence of this human factor will not only increase the difficulty of operation, but also reduce the welding quality of the final product. Summary of the invention

[0005] In view of this, the present invention provides a metal aluminum alloy camera module laser welding machine, which can overcome the shortcomings of the existing aluminum alloy camera laser welding machine that the upper mold position is easily offset during use, and it is difficult to ensure that the camera shell can be placed completely flat every time, thus affecting the accuracy and efficiency of subsequent welding work.

[0006] A metal aluminum alloy camera module laser welding machine comprises: a control cabinet; a shell connected to the top of the control cabinet; an electric turntable installed inside the shell; a mounting seat symmetrically connected to the top of the electric turntable; a sliding seat symmetrically slidably connected to the side of the mounting seat and moving up and down; a pressure sensor installed on the mounting seat, and the bottom of the sliding seat on the lower side contacts the top of the pressure sensor; a servo electric cylinder installed on the side of the mounting seat away from the sliding seat, and the telescopic rod of the servo electric cylinder is connected to the sliding seat on the upper side; a servo motor installed on the sliding seat; an upper mold installed on the output shaft of the servo motor on the upper side; a lower mold installed on the output shaft of the servo motor on the lower side; a detection component installed inside the shell, used to detect whether the camera body is placed flat; a laser welding component installed inside the shell, used to perform laser welding on the camera body.

[0008] Further description, the laser welding assembly includes: a three-axis motion module, installed on the bottom of the shell; a self-melting laser welding head, installed on the motion platform of the three-axis motion module, so that the three-axis motion module can control the self-melting laser welding head to perform adaptive three-axis movement according to the rotation angle of the camera body.

[0009] Further description also includes: a pre-welding and post-welding inspection camera, which is installed on the motion platform of the three-axis motion module, and the pre-welding and post-welding inspection camera is located on the side of the self-melting laser welding head and is used to shoot the welding process of the camera body.

[0010] Further description, it also includes: an iron partition connected to the top of the electric turntable, and the iron partition is located between the two mounting seats.

[0011] Further description, it also includes: an electric push rod installed on the side of the sliding seat at the lower side; a placement plate connected to the telescopic rod of the electric push rod, and the lower mold slides through the middle of the placement plate.

[0012] Further description, it also includes: a mounting block connected to the side of the servo motor on the lower side; a slide rod slidably connected to the mounting block, and the slide rod slides through the placement plate; a baffle frame connected to the upper end of the slide rod, and the baffle frame covers the outside of the placement plate, a connecting spring wrapped around the outside of the slide rod, and the two ends of the connecting spring are respectively connected to the placement plate and the baffle frame.

[0013] Further description, it also includes: a smoke exhaust pipe, connected to the outer shell, and the upper end of the smoke exhaust pipe passes through the top of the outer shell; a drive motor, installed at the inner bottom of the outer shell; a mounting rod, installed at the inner bottom of the outer shell, and the mounting rod is located above the drive motor; a rotating tube, rotatably connected to the mounting rod, the rotating tube is connected to the output shaft of the drive motor, and one end of the rotating tube is rotatably connected to the lower end of the smoke exhaust pipe and maintains communication.

[0014] The beneficial effects of the present invention are as follows: 1. The present invention can ensure that the upper mold remains stable during the process of applying pressure to the camera housing by designing a servo electric cylinder and a sliding seat, thereby avoiding a decrease in welding accuracy due to upper mold position offset, so as to achieve the purpose of precise control of the upper mold, thereby solving the problem of easy offset of the upper mold position in the prior art, ensuring the accuracy and consistency of the welding process, and improving the welding quality.

If the camera body is not placed flat, the receiver cannot receive the infrared light beam, and the alarm will sound an alarm to prompt the operator to make adjustments. This can effectively solve the problem of uneven placement of the camera shell due to the lack of an effective positioning device in the prior art, ensure that the camera shell can remain flat each time it is placed, and improve the success rate of welding and the quality of the product.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] Embodiment: A laser welding machine for a metal aluminum alloy camera module, such as Figure 1-Figure 5 As shown, it includes a control cabinet 1, a shell 2, an electric turntable 3, a mounting seat 4, a sliding seat 5, a pressure sensor 6, a servo electric cylinder 7, a servo motor 8, an upper mold 9, a lower mold 10, a detection component and a laser welding component. The control cabinet 1 is used to control the electrical components of the laser welding machine to run according to a preset program. The top of the control cabinet 1 is connected to the shell 2, and the front side of the shell 2 is an open design, which is convenient for the operator to put and take materials from the camera body 001. The electric turntable 3 is installed on the front side of the lower part of the shell 2. Two mounting seats 4 are symmetrically connected to the top of the electric turntable 3. The sliding seats 5 are symmetrically slidably connected to one side of the two mounting seats 4, and the pressure sensors 6 are installed at the bottom of the two mounting seats 4. , and the bottom of the sliding seat 5 on the lower side is in contact with the top of the pressure sensor 6, a servo electric cylinder 7 is installed on the other side of the two mounting seats 4, and the telescopic rod of the servo electric cylinder 7 is connected to the sliding seat 5 on the upper side, and the servo electric cylinder 7 is used to control the upper sliding seat 5 to move up and down, and a servo motor 8 is installed on the two sliding seats 5, and an upper mold 9 is installed on the output shaft of the servo motor 8 on the upper side, and a lower mold 10 is installed on the output shaft of the servo motor 8 on the lower side, and the lower mold 10 is vertically aligned with the upper mold 9, and a detection component for detecting whether the camera body 001 is placed flat is installed inside the shell 2, and a laser welding component for laser welding the camera body 001 is also installed inside the shell 2.

[0027] like Figure 1-Figure 4 As shown, the detection assembly includes a receiver 11, a mounting plate 12, an infrared transmitter 13 and an alarm 14. The receiver 11 is installed on one side of the two mounting seats 4 close to the sliding seat 5. The mounting plate 12 is connected to the front lower part of the right side of the inner wall of the shell 2. The infrared transmitter 13 is installed on the upper end of the mounting plate 12. The infrared transmitter 13 is flush with the height of the receiver 11. The alarm 14 is installed in the middle of the left side of the mounting plate 12. Figure 4 As shown, if the camera body 001 is placed flat, the infrared light beam 002 emitted by the infrared transmitter 13 can just pass over the top of the camera body 001 and be received by the receiver 11. If the camera body 001 is not placed flat, the camera body 001 will block the infrared light beam 002 emitted by the infrared transmitter 13, causing the receiver 11 to be unable to receive the infrared light beam 002, and the alarm 14 will sound an alarm.

[0028] like Figure 5 As shown, the laser welding assembly includes a three-axis motion module 15, a self-melting laser welding head 16, a pre-welding and post-welding detection camera 17 and an iron partition 18. The three-axis motion module 15 is installed on the rear side of the bottom of the housing 2, and a laser distance sensor (not shown) and a self-melting laser welding head 16 are installed on the motion platform of the three-axis motion module 15. The laser distance sensor is used to detect the distance between it and the camera body 001. The laser distance sensor and the self-melting laser welding head 16 are fixed together. When debugging the welding trajectory, the distance between the laser distance sensor and the camera body 001 at different positions of the self-melting laser welding head 16 can be detected and recorded and used as a calibration. When the position of the three-axis motion module 15 or the self-melting laser welding head 16 deviates, the distance between the laser distance sensor and the camera body 001 will definitely shift, thereby sending an alarm signal. At the same time, through the action of the laser ranging sensor, the three-axis motion module 15 can control the self-melting laser welding head 16 to adaptively move in three axes according to the rotation angle of the camera body 001. A pre-welding and post-welding detection camera 17 is also installed on the motion platform of the three-axis motion module 15. The pre-welding and post-welding detection camera 17 is located on the left side of the self-melting laser welding head 16. The pre-welding and post-welding detection camera 17 consists of a pre-welding visual camera and a post-welding visual camera. The pre-welding visual camera is used to correct the welding ribs to prevent the welding trajectory from deviating from the actual welding rib plane. The post-welding visual camera is used to detect whether there are defects such as welding deviation, depression, and undercut on the appearance of the welding ribs. During the welding process, temperature collection and analysis can be performed in real time (if the temperature exceeds the set upper limit, the equipment will send an alarm signal). An iron partition 18 is connected to the middle of the top of the electric turntable 3, and the iron partition 18 is located between the two mounting seats 4.

[0029] First, according to the different types of camera bodies 001, upper molds 9 and lower molds 10 of different specifications are selected and installed on the output shafts of the two servo motors 8 respectively. Then, the three-axis motion module 15 is controlled by the control cabinet 1 to drive the self-melting laser welding head 16 to move up, down, left and right, so as to adjust the height of the self-melting laser welding head 16 according to the height of the gap between the upper and lower shells of the camera body 001, and align the self-melting laser welding head 16 with the middle position of the upper mold 9 and the lower mold 10; then, the operator places the assembled camera body 001 on the lower mold 10 on the front side, and then controls the infrared transmitter 13 to emit an infrared light beam 002 through the control cabinet 1. If the camera body 001 is not placed flat, the camera body 001 will block the infrared light beam 002 emitted by the infrared transmitter 13, causing the receiver 11 on the front side to be unable to receive the infrared light beam 002. The receiver 11 on the front side will send a signal, and the control cabinet 1 will control the alarm after receiving the signal. The device 14 sounds an alarm to remind the operator that the camera body 001 is not placed flat. At this time, the operator adjusts the position of the camera body 001 until the camera body 001 is placed flat. At this time, the infrared light beam 002 emitted by the infrared transmitter 13 can just pass over the top of the camera body 001 and be received by the receiver 11 on the front side. The control cabinet 1 will control the alarm 14 to stop sounding the alarm; then the servo electric cylinder 7 on the front side drives the upper sliding seat 5 to move downward, so as to drive the servo motor 8 and the upper mold 9 on the upper side to move downward, until the upper mold 9 is pressed on the camera body 001. The upper sliding seat 5 continues to move downward, which will gradually increase the pressure on the pressure sensor 6. When the pressure on the pressure sensor 6 reaches the preset value, the pressure sensor 6 will send a signal. After receiving the signal, the control cabinet 1 will control the servo electric cylinder 7 on the front side to stop working, so as to ensure that the upper mold 9 and the lower mold 10 can cooperate to press the camera body 001;Then, the control cabinet 1 controls the electric turntable 3 to rotate 180 degrees, and the electric turntable 3 can drive the two mounting seats 4 to rotate 180 degrees to exchange positions front and back. Repeat the above operation to place the next camera body 001 between another set of upper molds 9 and lower molds 10. During the placement of the next camera body 001, the control cabinet 1 will control the self-melting laser welding head 16 to start working. At the same time, the control cabinet 1 will control the two servo motors 8 to drive the upper mold 9 and the lower mold 10 to rotate synchronously to drive the camera body 001 to rotate, so that the self-melting laser welding head 16 can be placed between the upper mold 9 and the lower mold 10. The welding head 16 performs laser welding on the gap between the upper and lower shells of the camera body 001. During the rotation of the camera body 001, the distance between the camera body 001 and the self-melting laser welding head 16 will change, and the laser ranging sensor on the three-axis motion module 15 can monitor the distance between the camera body 001 and the self-melting laser welding head 16 in real time, and can control the three-axis motion module 15 through the control cabinet 1 to drive the self-melting laser welding head 16 to move back and forth adaptively, so as to ensure that the camera body 001 and the self-melting laser welding head 1 are in the same distance during the welding process. 6 are consistent, thereby ensuring the welding effect, and during the welding process, the iron partition 18 can block the scattered laser to prevent the operator from being hurt, and the pre-welding and post-welding inspection camera 17 can not only correct the welding ribs to prevent the welding trajectory from deviating from the actual welding rib plane, but also detect whether there are defects such as welding deviation, depression, and undercut on the appearance of the welding ribs. After the welding is completed, the control cabinet 1 will control the self-melting laser welding head 16 to stop working, and the control cabinet 1 will control the upper mold 9 and the lower mold 10 to stop rotating, and control the servo electric cylinder 7 to drive the upper sliding seat 5 to move upward and reset, so as to bring The servo motor 8 and upper mold 9 on the upper side are moved upward to reset, so that the upper mold 9 is separated from the welded camera body 001. Repeat the above operation, and the welded camera body 001 can be driven by the electric turntable 3 to rotate 180 degrees to the front side of the shell 2 for manual picking, and the next camera body 001 will rotate 180 degrees to the side close to the self-melting laser welding head 16 for laser welding. Since the upper mold 9 and the lower mold 10 are respectively controlled by two servo motors 8 to rotate and stop synchronously, the upper mold 9 and the lower mold 10 can always maintain a vertical alignment state. ;

[0030] like Figure 6 and Figure 7As shown, it also includes an electric push rod 19, a placement plate 20, a mounting block 21, a slide bar 22, a stop frame 23 and a connecting spring 24. The two lower sliding seats 5 are both installed with electric push rods 19 on their sides. The placement plate 20 is connected to the telescopic rod of the electric push rod 19, and the lower mold 10 slides through the middle of the placement plate 20. The two lower servo motors 8 are both connected with mounting blocks 21 on their sides. The mounting blocks 21 are slidably connected with the slide bar 22. A limiting circular plate is provided at the lower end of the slide bar 22. The diameter of the limiting circular plate is greater than the diameter of the slide bar 22. The slide bar 22 slides through the placement plate 20. A stop frame 23 is connected to the upper end of the slide bar 22. The stop frame 23 is annular in shape, and the stop frame 23 covers the outer side of the placement plate 20. A connecting spring 24 is wound around the outer side of the slide bar 22, and the two ends of the connecting spring 24 are respectively connected to the placement plate 20 and the stop frame 23.

[0031] After the operator places the camera body 001 on the lower mold 10 on the front side, the connecting wire reel on the camera body 001 can be placed on the top of the placement plate 20. The blocking frame 23 can block the connecting wires of the camera body 001 in the placement plate 20 to prevent the connecting wires from falling, thereby avoiding the connecting wires from affecting the subsequent welding work of the camera body 001. When the operator needs to take out the welded camera body 001, the telescopic rod of the electric push rod 19 can be controlled by the control cabinet 1 to extend to drive the placement plate 20 to move upward. The placement plate 20 can drive the connecting wires of the camera body 001 thereon to move upward, and the placement plate 20 can drive the blocking frame 23 and the sliding rod 22 to move upward through the connecting spring 24. When the top of the placement plate 20 contacts the welded camera body 001, it can also push the camera body 001 to move upward. Figure 7 As shown, when the limiting circular plate at the lower end of the slide bar 22 contacts the bottom of the mounting block 21, the slide bar 22 and the baffle frame 23 will stop moving upward, while the placement plate 20 will continue to move upward, and the connecting spring 24 will be compressed so that the baffle frame 23 will no longer block the outside of the placement plate 20. At this time, the placement plate 20 will push the camera body 001 and the connecting wire thereon to move upward until the camera body 001 is separated from the lower mold 10, so that the operator can take out the welded camera body 001. Then the control cabinet 1 will control the telescopic rod of the electric push rod 19 to shorten, so as to drive the placement plate 20 to move downward and reset. The connecting spring 24 gradually returns to its original state, and then the placement plate 20 can drive the baffle frame 23 and the slide bar 22 to move downward and reset through the connecting spring 24.

[0032] like Figure 8As shown, it also includes a smoke exhaust pipe 25, a drive motor 26, a mounting rod 27 and a rotating tube 28. The smoke exhaust pipe 25 is connected to the left side of the upper part of the shell 2, and the upper end of the smoke exhaust pipe 25 passes through the top of the shell 2. The upper end of the smoke exhaust pipe 25 is used for an external vacuum pump. The drive motor 26 and the mounting rod 27 are connected to the left side of the inner bottom of the shell 2. The shape of the mounting rod 27 is an inverted U shape, and the mounting rod 27 is located above the drive motor 26. The middle of the upper part of the mounting rod 27 is rotatably connected to the rotating tube 28. The shape of the rotating tube 28 is L-shaped. The middle part of the rotating tube 28 is connected to the output shaft of the drive motor 26, and one end of the rotating tube 28 is rotatably connected to the lower end of the smoke exhaust pipe 25 and maintains communication; during the welding process of the camera body 001, the rotating The other end of the moving tube 28 will be aligned with the camera body 001, and the vacuum pump externally connected to the upper end of the smoke exhaust pipe 25 will be started at the same time. The vacuum pump can draw air from the smoke exhaust pipe 25 and the rotating tube 28, so that suction will be generated at the end of the rotating tube 28 close to the camera body 001, thereby sucking away the smoke generated during the welding of the camera body 001. When the electric turntable 3 is about to drive the two mounting seats 4 to rotate one hundred and eighty degrees to exchange their positions front and back, the control cabinet 1 will first control the drive motor 26 to drive the rotating tube 28 to rotate backward ninety degrees to prevent the mounting seat 4 from colliding with the rotating tube 28 during rotation. When the electric turntable 3 stops rotating, the control cabinet 1 will control the drive motor 26 to drive the rotating tube 28 to reverse ninety degrees and reset.

[0033] The above is a detailed introduction to the present application. Specific examples are used in this article to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method of the present application and its core idea. At the same time, for general technical personnel in this field, according to the idea of ​​the present application, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
