[0031] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0032] To facilitate understanding by those skilled in the art, the present application describes the specific implementation process of the technical solution provided by the present application through the following embodiments.

[0033] See also Figure 1 - Figure 2 The present application provides a welding laser center calibration device for a camera module, comprising: a spot inspection rod 1, an energy spot inspection instrument 2, a base 3 and a lifting platform 4; the base 3 is arranged on the upper surface of the lifting platform 4, and the base 3 is driven to move upward by the lifting platform 4; the energy spot inspection instrument 2 is installed on the base 3, the spot inspection rod 1 is vertically arranged on the upper surface of the energy spot inspection instrument 2, and the spot inspection rod 1 is provided with a detection channel 101 passing through its upper and lower surfaces along its center line, wherein the detection channel 101 is vertically arranged, and its upper end is connected to the laser welding head, when working, the laser energy emitted by the laser welding head can pass through the detection channel 101 and fall on the energy spot inspection instrument 2, thereby The laser emitted by the optical welding head is tested for verticality, so that the state of the laser can be quickly obtained. When the laser is tilted, the position of the laser welding head is adjusted so that the laser falls on the corresponding position of the energy spot detector 2, thereby ensuring the vertical setting of the laser; and the lifting platform 4 is used to adjust the height of the spot inspection rod 1, so that the detection channel 101 of the spot inspection rod 1 can accurately cooperate with the laser welding head, thereby ensuring the detection and calibration work; therefore, in the present application, the laser state can be quickly detected, mainly the verticality of the laser is detected, and the laser is quickly adjusted and calibrated when it is tilted to ensure the vertical setting of the laser, and the present application is easy to adjust and has high calibration accuracy, which can ensure the subsequent welding quality.

[0034] During the specific detection work, the energy spot detector 2 is horizontally set on the base 3, and the inspection rod 1 is vertically set on the energy spot detector 2, and the detection channel 101 is in a vertical state, and the center line of the detection channel 101 is aligned with the center of the energy spot detector 2, and then the laser welding head is placed at the upper end of the detection channel 101, specifically, the laser port of the laser welding head is located at the center line of the detection channel 101, when the laser energy emitted by the laser port falls along the center line of the detection channel 101 to the center line point of the energy spot detector 2, it proves that the laser is not tilted, and if the laser falls outside the center line point of the energy detector 2, that is, the laser emitted by the laser port does not fall on the center line point of the energy detector 2, and an offset occurs, it proves that the laser is tilted, and at this time, it is necessary to adjust the position of the laser welding head to calibrate the verticality of the laser.

[0035] It is worth noting that in the present application, when the laser is tilted, the position of the laser welding head can be adjusted manually or by a robot, thereby adjusting the laser state to ensure that the laser is set vertically.

[0036] Furthermore, the upper end of the detection channel 101 is threadedly connected to the laser welding head, so that the laser welding head is stably set on the inspection rod 1 and the laser state detection is stably performed.

[0037] For further information, see Figure 1 - Figure 4 A connecting block 201 is provided on the upper surface of the energy spot detector 2, and the connecting block 201 is provided with a through hole 202 penetrating the upper and lower surfaces thereof; a connecting groove 102 is provided at the lower end of the spot inspection rod 1, and the connecting groove 102 is communicated with the detection channel 101; the connecting block 201 is correspondingly inserted into the connecting groove 102, so that the spot inspection rod 1 is installed on the energy spot detector 2, and at the same time, the through hole 202 corresponds to the detection channel 101, so that the laser of the laser welding head can pass through the detection channel 101 and the through hole 202 and fall onto the energy spot detector 2.

[0038] For further information, see Figure 1 - Figure 2 , Figure 4 - Figure 5 The upper surface of the base 3 is provided with a mounting groove 301, and the structure of the mounting groove 301 corresponds to the energy spot detector 2, so that the energy spot detector 2 is correspondingly arranged in the mounting groove 301. At the same time, the upper surface of the base 3 is provided with a receiving groove 302, and the receiving groove 302 is connected with the mounting groove 301; and the side of the energy spot detector 2 is provided with a handle 203. After the energy spot detector 2 is installed in the mounting groove 301, the handle 203 extends from the receiving groove 302 to the outside of the base 3. The handle 203 is used to provide a gripping position to facilitate the operation of the energy spot detector 2.

[0039] For further information, see Figure 5 - Figure 6 A plurality of first connection holes 303 are provided on the base 3, and a plurality of second connection holes 43 are provided on the upper surface of the lifting platform 4. The first connection holes 303 correspond to the second connection holes 43 one by one. Bolts are installed in the corresponding first connection holes 303 and second connection holes 43 to fix the base 3 on the lifting platform 4.

[0040] For further information, see Figure 6 - Figure 8 , the lifting platform 4 includes a support seat 41 and an adjustment seat 42; the adjustment seat 42 is movably arranged on the support seat 41; specifically, a cylinder 411 and a rotating block 412 are arranged on the adjustment seat 42, and the rotating block 412 is rotatably arranged on the adjustment seat 42, and the cylinder 411 is installed on the adjustment seat 42 and is located on the side of the rotating block 412. The cylinder 411 is used to drive the rotating block 412 to rotate and let the rotating block 412 push the adjustment seat 42 during the rotation process, so as to drive the adjustment seat 42 to move upward, and thereby increase the height of the inspection rod 1, so that the detection channel 101 can contact the laser welding head accordingly. Specifically, an output rod is provided on the cylinder 411, and the output rod is connected to the rotating block 412. When the cylinder 411 is operating, the output rod will extend outward and move, thereby driving the rotating block 412 connected to it to rotate; at the same time, by controlling the extension length of the output rod of the cylinder 411, the adjustment distance of the adjustment seat 42 can be controlled, and the cylinder 411 is connected to the solenoid valve, and the solenoid valve controls the telescopic movement of the cylinder 411.

[0041] For further information, see Figure 6 - Figure 8 A clamping block 421 is provided at the bottom surface of the adjustment seat 42, and the rotating block 412 is Y-shaped and makes one side structure abut against the clamping block 421 when rotating, so as to drive the adjustment seat 42 to move. Specifically, when the cylinder 411 is not in operation and the output rod is not extended outward, the adjustment seat 42 is in the original state, that is, the adjustment seat 42 is not moved upward. At this time, one side structure of the rotating block 412 is abutted against the clamping block 421. When the cylinder 411 is in operation and the output rod is extended outward, the output rod drives the connected rotating block 412 to rotate. Since one side structure of the rotating block 412 is abutted against the clamping block 421, the one side structure of the rotating block 412 can drive the adjustment seat 42 to move.

[0042] In another embodiment, the cylinder 411 can be replaced by a micrometer, the screw on the micrometer is connected to the rotating block 412, and the screw of the micrometer moves to drive the rotating block 412 to rotate, thereby pushing the adjustment seat 42. In addition, the moving distance of the adjustment seat 42 can be accurately adjusted by the scale on the micrometer. Specifically, when the micrometer is not rotated manually, the micrometer is not operated, and the screw on the micrometer does not extend outward and move, the adjustment seat 42 is in the original state, that is, the adjustment seat 42 does not move upward. At this time, a side structure of the rotating block 412 is abutted against the clamping block 421. When the micrometer is manually rotated to operate, the screw on the micrometer will extend outward and move, and the screw drives the rotating block 412 connected thereto to rotate. Since a side structure of the rotating block 412 is abutted against the clamping block 421, a side structure of the rotating block 412 can drive the adjustment seat 42 to move.

[0043] It is worth noting that the adjustment seat 42 is driven upward by the cylinder 411 or the micrometer and the rotating block 412 to change the height of the inspection rod 1. When the output rod of the cylinder 411 is retracted, the adjustment seat 42 will move downward under the action of gravity to return the inspection rod 1 to its original position.

[0044] For further information, see Figure 6 - Figure 8 A fixing plate 413 is provided on the side of the support seat 41, and a slide groove 414 is provided on the fixing plate 413; a slider 422 is provided on the side of the adjustment seat 42, and the slider 422 is arranged in the slide groove 414. Through the cooperation between the slider 422 and the slide groove 414, the moving direction of the adjustment seat 42 is limited and guided to ensure that the adjustment seat 42 moves vertically upward.

[0045] For further information, see Figure 6 - Figure 8 , the adjusting seat 42 is provided with a guide groove 424, and the supporting seat 41 is provided with a guide block 415, which is correspondingly inserted into the guide groove 424. Specifically, two limit blocks 423 are arranged on the adjusting seat 42 at intervals, and a guide groove 424 is formed between the two limit blocks 423, and two guide blocks 415 are arranged on the supporting seat 41, and the two guide blocks 415 are respectively placed on both sides of the guide groove 424, and the guide blocks 415 and the guide groove 424 are slidably matched, so that the adjusting seat 42 moves upward along the guide blocks 415.

[0046] It is worth noting that anti-collision blocks can be set at the bottom ends of the two limit blocks 423. The anti-collision blocks are made of soft materials, such as silicone, to prevent the limit blocks 423 from being damaged by collision during movement and to achieve shock absorption.

[0047] The specific adjustment process of this application is: place the calibration device under the laser welding head, then adjust the height of the spot inspection rod 1 and the energy spot inspection instrument 2, so that the upper end of the detection channel 101 of the spot inspection rod 1 corresponds to the laser welding head, and the laser welding head is melted into the detection channel 101. At this time, keep the detection channel 101 vertical, and then check the laser state emitted by the laser welding head. When the laser energy emitted by the laser port of the laser welding head falls along the center line of the detection channel 101 to the center line point of the energy spot inspection instrument 2, it proves that the laser is not tilted. If the laser falls outside the center line point of the energy detector 2, that is, the laser emitted by the laser port does not fall on the center line point of the energy detector 2, and an offset occurs, it proves that the laser is tilted. At this time, it is necessary to adjust the position of the laser welding head to calibrate the laser verticality of the laser welding head.

[0048] Compared with the prior art: the welding laser center calibration device of the camera module of the present application comprises: a spot inspection rod 1, an energy spot inspection instrument 2, a base 3 and a lifting platform 4; the base 3 is arranged on the upper surface of the lifting platform 4, and the base 3 is driven to move upward by the lifting platform 4; the energy spot inspection instrument 2 is installed on the base 3, the spot inspection rod 1 is vertically arranged on the upper surface of the energy spot inspection instrument 2, and the spot inspection rod 1 is provided with a detection channel 101 passing through its upper and lower surfaces along its center line, wherein the detection channel 101 is vertically arranged, and its upper end is connected to the laser welding head, and when working, the laser emitted by the laser welding head can pass through the detection channel 101 and fall on the energy spot inspection instrument 2, In this way, the verticality of the laser is detected, so that the state of the laser can be quickly obtained. When the laser is tilted, the position of the laser welding head is adjusted manually or by a robot so that the laser falls on the corresponding position of the energy spot detector 2, thereby ensuring that the laser is set vertically; and the lifting platform 4 is used to adjust the height of the spot inspection rod 1, so that the detection channel 101 of the spot inspection rod 1 can accurately cooperate with the laser welding head, thereby ensuring the detection and calibration work; therefore, in the present application, the laser state can be quickly detected, and the laser can be quickly adjusted and calibrated when it is tilted to ensure that the laser is set vertically, and the present application is easy to adjust and has high calibration accuracy, which can ensure the subsequent welding quality.
