Description

Technical Field

[0001] The utility model relates to the field of optical machine module production, and particularly relates to a galvanometer and a laser welding machine. Background Art

[0002] At present, during the assembly of a micro galvanometer in an optical machine module, the stainless steel iron sheet and iron part of the micro galvanometer are mainly fixed by screws. Using screws for fixation not only makes the manufacturing process cumbersome, time-consuming, and has low production efficiency, but also the screw caps will occupy the internal space of the optical machine. Fixing the stainless steel iron sheet and iron part of the micro galvanometer by welding can avoid the situation where the screw caps occupy the internal space of the optical machine. However, the existing welding machines can only weld one flat product at a time, and it is easy to have poor welding when there are tolerances in the materials, which reduces the production efficiency, increases the scrap rate of components, and at the same time cannot meet the welding requirements for products with height differences. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is to overcome the defect that the connection structure of the galvanometer occupies a large space by using fasteners in the prior art, and to provide a galvanometer and a laser welding machine.

[0004] The utility model solves the above technical problem by the following technical solutions:

[0005] A galvanometer includes a carrier seat and a rotating seat, and a first connection area between the carrier seat and the rotating seat is connected by welding.

[0006] By connecting the carrier seat and the rotating seat by welding, there is no need to set screw holes on the carrier seat and the rotating seat for screwing to fix the carrier seat and the rotating seat, which reduces the volume of the carrier seat and the rotating seat, and further reduces the volume of the entire galvanometer.

[0007] Preferably, the galvanometer includes an optical component, the carrier seat has a first hollow part for accommodating the optical component, the number of the first connection areas is two, and the two first connection areas are respectively arranged on both sides of the first hollow part.

[0008] Preferably, the galvanometer further includes a base, and a second connection area between the base and the rotating seat is connected by welding.

[0009] By welding the base and the rotating seat, there is no need to set screw holes on the base and the rotating seat for screwing to fix the base and the rotating seat, and there is no screw cap occupying space in the entire galvanometer, further reducing the volume of the galvanometer.

[0010] Preferably, the galvanometer includes an optical component, and the rotating base has a second hollow portion for exposing the optical component. The number of the second connection regions is two, and the two second connection regions are respectively arranged on both sides of the second hollow portion.

[0011] A laser welding machine for assembling a galvanometer, the laser welding machine includes a laser welding part, an equipment frame, and a galvanometer carrier. The laser welding machine further includes:

[0012] A first bearing platform and a first driving mechanism. The first bearing platform bears the galvanometer carrier, and the driving end of the first driving mechanism is connected to the first bearing platform and is used to drive the first bearing platform to reciprocate along a first horizontal direction;

[0013] A second bearing platform and a second driving mechanism. The second bearing platform bears the first driving mechanism, and the driving end of the second driving mechanism is connected to the second bearing platform and is used to drive the second bearing platform to reciprocate along a second horizontal direction. The second driving mechanism is arranged on the bottom platform of the equipment frame, and the first horizontal direction and the second horizontal direction are different;

[0014] An attachment interface and a third driving mechanism. The laser welding part is arranged on the attachment interface, and the third driving mechanism is arranged on the column of the equipment frame. The driving end of the third driving mechanism is connected to the attachment interface and is used to drive the attachment interface to move along the vertical direction.

[0015] In this technical solution, by providing a first bearing platform and a first driving mechanism on the laser welding machine, and a second bearing platform and a second driving mechanism, the galvanometer carrier can move along the first horizontal direction and the second horizontal direction. When there are tolerances in the parts of the galvanometer, the position of the galvanometer carrier on the galvanometer is adjusted by driving the mechanism to adjust the position of the galvanometer carrier in the first horizontal direction and the second horizontal direction, so as to reduce the occurrence of poor welding. At the same time, by driving the attachment interface by the third driving mechanism to drive the laser welding part to move along the height direction, the height of the welding point of the laser welding part can be adjusted, so as to realize the welding of the galvanometer with a step difference, meet the current welding requirements for the galvanometer, and especially meet the welding requirements for the micro galvanometer.

[0016] Preferably, the laser welding machine further includes an imaging camera. The imaging camera is arranged on the attachment interface. The center point of the focal plane of the imaging camera is set to coincide with the welding point of the laser welding part. The imaging camera is electrically connected to the third driving mechanism.

[0017] In this technical solution, an imaging camera is provided on the attachment interface. The imaging camera can clearly locate the weld position of the galvanometer by adjusting its height. When the imaging of the galvanometer by the imaging camera is unclear due to the misalignment of the focal plane, the height of the attachment interface is adjusted by the third driving mechanism to further adjust the position of the focal plane of the imaging camera, so that the imaging camera can take clear images. The focal plane is located on the galvanometer. At this time, due to the relationship between the imaging camera and the laser welding part structure, the welding point of the laser welding part is also located on the galvanometer. Therefore, precise welding can be achieved without manual positioning. The above structural setting solution improves the reliability of the laser welding machine, improves the welding efficiency, and the implementation solution is relatively simple. It only requires the third driving mechanism to drive the imaging camera to lift and lower to align with the galvanometer.

[0018] Preferably, a plurality of clamping parts are provided on the galvanometer carrier, and the plurality of clamping parts are used to respectively fix the plurality of galvanometers.

[0019] In this technical solution, by providing a plurality of clamping parts on the galvanometer carrier, the galvanometer carrier can fix a plurality of galvanometers at the same time. Since the first driving mechanism and the second driving mechanism enable the galvanometer carrier to move in the first horizontal direction and the second horizontal direction, the movement of the galvanometer carrier enables the laser welding part to weld the galvanometers at different positions on the galvanometer carrier, realizing welding of a plurality of galvanometers in one loading, and improving the welding efficiency.

[0020] Preferably, the laser welding machine further includes a first guide rail and a first slider that cooperate with each other. The first guide rail is provided on the first bearing platform, and the first guide rail extends along the first horizontal direction. The first slider is connected to the first bearing platform to enable the first bearing platform to reciprocate along the extension direction of the first guide rail;

[0021] And / or, the laser welding machine further includes a second guide rail and a second slider that cooperate with each other. The second guide rail is provided on the bottom platform, and the second guide rail extends along the second horizontal direction. The second slider is connected to the second bearing platform to enable the second bearing platform to reciprocate along the extension direction of the second guide rail;

[0022] And / or, the laser welding machine further includes a third guide rail and a third slider. The third guide rail is provided on the column, and the third guide rail extends in the vertical direction. The third slider is connected to the attachment interface to enable the attachment interface to reciprocate along the extension direction of the third guide rail.

[0023] In this technical solution, by providing the first guide rail, the first slider, the second guide rail, the second slider, the third guide rail, and the third slider, when the first bearing platform, the second bearing platform, and the attachment interface move in the set direction, they are more stable, do not deviate from the set movement direction, and move more smoothly.

[0024] Preferably, the bottom platform of the laser welding machine is rectangular, the galvanometer carrier is rectangular, and the second horizontal direction is parallel to the extending direction of the long side of the bottom platform.

[0025] In this technical solution, by setting the second horizontal direction to be parallel to the extending direction of the long side of the bottom platform, the galvanometer carrier has a greater degree of freedom of movement on the bottom platform, expanding the range where the clamping part can be set, thereby increasing the upper limit of the number of clamping parts and further improving the production line efficiency.

[0026] Preferably, the galvanometer carrier, the first bearing platform, and the second bearing platform are arranged in sequence from top to bottom.

[0027] Preferably, the clamping part is centrally arranged on the galvanometer carrier;

[0028] And / or, the clamping part is rectangular, and the sides of the clamping part are parallel to the sides of the galvanometer carrier.

[0029] In this technical solution, by setting the clamping part to be rectangular and the sides of the clamping part to be parallel to the sides of the galvanometer carrier, the number of clamping parts arranged on the galvanometer carrier can be maximized, improving the production efficiency.

[0030] Preferably, the first driving mechanism is a motor;

[0031] And / or, the second driving mechanism is a motor;

[0032] And / or, the third driving mechanism is a motor.

[0033] Preferably, the included angle between the first horizontal direction and the second horizontal direction is greater than or equal to 45°.

[0034] Preferably, the included angle between the first horizontal direction and the second horizontal direction is equal to 90°.

[0035] The positive and progressive effects of the present utility model are as follows: By arranging the first bearing platform and the first driving mechanism on the laser welding machine, and arranging the second bearing platform and the second driving mechanism, the galvanometer carrier can move along the first horizontal direction and the second horizontal direction. When there are tolerances in the parts of the galvanometer, the position of the galvanometer carrier is adjusted in the first horizontal direction and the second horizontal direction through the driving mechanism to adjust the position of the galvanometer on the galvanometer carrier, so as to reduce the occurrence of poor welding. At the same time, the third driving mechanism drives the locking interface to drive the laser welding part to move in the height direction, and the height of the welding point of the laser welding part can be adjusted, thereby realizing the welding of the galvanometer with a step difference and meeting the current welding requirements for the galvanometer, especially the welding requirements for the micro galvanometer.

[0075] The following gives two preferred embodiments and, in conjunction with the accompanying drawings, more clearly and completely illustrates the present utility model.

[0076] Embodiment 1 is as follows Figures 1-5As shown, this embodiment provides a laser welding machine 001 for the assembly of a galvanometer 11. The laser welding machine 001 includes a laser welding part 1, an equipment frame, and a galvanometer carrier 3, and further includes a first bearing platform 4 and a first driving mechanism 5, a second bearing platform 6 and a second driving mechanism 7, as well as a locking interface 8 and a third driving mechanism 9. The first bearing platform 4 bears the galvanometer carrier 3, and the driving end of the first driving mechanism 5 is connected to the first bearing platform 4 and is used to drive the first bearing platform 4 to reciprocate along the first horizontal direction (i.e., along the Y-axis in this embodiment). The second bearing platform 6 bears the first driving mechanism 5, and the driving end of the second driving mechanism 7 is connected to the second bearing platform 6 and is used to drive the second bearing platform 6 to reciprocate along the second horizontal direction (i.e., along the X-axis in this embodiment). The second driving mechanism 7 is arranged on the bottom platform 15 of the equipment frame. The laser welding part 1 is arranged on the locking interface 8, the third driving mechanism 9 is arranged on the column 2 of the equipment frame, and the driving end of the third driving mechanism 9 is connected to the locking interface 8 and is used to drive the locking interface 8 to move in the vertical direction (i.e., the Z-axis in this embodiment).

[0077] By arranging the first bearing platform 4 and the first driving mechanism 5 on the laser welding machine 001, and arranging the second bearing platform 6 and the second driving mechanism 7, the galvanometer carrier 3 can move along the first horizontal direction and the second horizontal direction. When there are tolerances in the parts of the galvanometer 11, the position of the galvanometer carrier 3 is adjusted in the first horizontal direction and the second horizontal direction respectively through the driving mechanisms, and the position of the galvanometer 11 on the galvanometer carrier 3 is adjusted to reduce the occurrence of poor welding. At the same time, by driving the locking interface 8 through the third driving mechanism 9 to drive the laser welding part 1 to move in the height direction (i.e., the Z-axis in this embodiment), the height of the welding point of the laser welding part 1 can be adjusted, so as to realize the welding of the galvanometer 11 with a step difference, meet the current welding requirements for the galvanometer 11, and especially meet the welding requirements for the micro galvanometer 11.

[0078] That is to say, in the laser welding machine 001 of this embodiment, the position of the galvanometer carrier 3 is adjusted in different directions on the horizontal plane through the first driving mechanism 5 and the second driving mechanism 7, that is, the position of the galvanometer 11 on the galvanometer carrier 3 is adjusted, which is convenient for the welding of the laser welding part 1. At the same time, the height of the mechanism welding part is adjusted in the vertical direction through the second driving mechanism 7, so that the laser welding part 1 can weld the galvanometer 11 with a step difference.

[0079] In this embodiment, as Figure 1 and Figure 2 shown, the laser welding machine 001 further includes an imaging camera 10, and the imaging camera 10 is arranged on the locking interface 8, as Figure 6 and Figure 7As shown, the center point 161 of the focal plane 16 of the imaging camera 10 is set to coincide with the welding point 101 of the laser welding part 1, and the imaging camera 10 is electrically connected to the third driving mechanism 9. By arranging the imaging camera 10 on the attachment interface 8, the imaging camera 10 can clearly locate the weld position of the galvanometer 11 by adjusting its height. Specifically, as Figure 7 shown, when the imaging camera 10 captures unclear images of the galvanometer 11 due to the misalignment of the focal plane 16, the height of the attachment interface 8 is adjusted through the third driving mechanism 9, and then the position of the focal plane 16 of the imaging camera 10 is adjusted ( Figure 7 the direction indicated by the arrow in the figure is the adjustment direction of the focal plane 16 and the welding point 101), so that the focal plane of the imaging camera 10 coincides with the galvanometer 11. At this time, due to the structural arrangement relationship between the imaging camera 10 and the laser welding part 1, the welding point of the laser welding part 1 is also located on the galvanometer 11. Therefore, precise welding can be achieved without manual positioning. The above structural arrangement scheme improves the reliability of the laser welding machine 001, also improves the welding efficiency, and the implementation scheme is relatively simple. It only requires the third driving mechanism 9 to drive the imaging camera 10 to lift and lower to align with the galvanometer 11. Among them, when the focal plane of the imaging camera 10 does not coincide with the galvanometer 11, the specific control principle and scheme for controlling the third driving mechanism 9 to drive the imaging camera 10 to lift and lower based on the coincidence situation of the images obtained by the imaging camera 10 belong to the category of existing technologies, so they will not be elaborated here.

[0080] Specifically, in this embodiment, the laser welding machine 001 further includes a moving door 12, control buttons 14, a computer mainframe (not shown in the figure), and a display screen 13. The computer mainframe is located inside the equipment chassis of the laser welding machine 001. After the galvanometer 11 is fixed on the galvanometer carrier 3 through the clamping part, the moving door 12 is closed, and the control button 14 is pressed. The computer mainframe will start to control the imaging camera 10 to capture images of the galvanometer 11 to be welded. When the images are not clear, the computer mainframe will adjust the height of the imaging camera 10 through the third driving mechanism 9. After the imaging is completed, welding will be performed. This part of the technical solution is controlled by the computer mainframe through software. During this process, the display screen 13 will display the relevant parameters of the welding. This part of the control method is an existing technology and will not be elaborated here.

[0081] In this embodiment, as Figure 5As shown in the figure, eight clamping parts are provided on the galvanometer carrier 3, and these clamping parts are used to fix eight galvanometers 11 respectively. By providing multiple clamping parts on the galvanometer carrier 3, the galvanometer carrier 3 can fix multiple galvanometers 11 at the same time. Since the first driving mechanism 5 and the second driving mechanism 7 enable the galvanometer carrier 3 to move in the first horizontal direction and the second horizontal direction, the movement of the galvanometer carrier 3 enables the laser welding part 1 to weld the galvanometers 11 at different positions on the galvanometer carrier 3, achieving the welding of multiple galvanometers 11 in one loading. Here, the welding of multiple galvanometers 11 is achieved by moving the galvanometer carrier 3, and the galvanometers 11 are welded in sequence, shortening the turnover time of the galvanometers 11 and improving the welding efficiency.

[0082] Specifically, in this embodiment, as Figure 3 shown, taking the center position of the bottom platform 15 of the equipment frame as the origin, a three-dimensional rectangular coordinate system is established. The horizontal direction is the mutually perpendicular X-axis and Y-axis, and the vertical direction is the Z-axis. After the camera takes an image, the software can calculate the corresponding coordinate points, and the laser welding part 1 performs welding at the corresponding positions.

[0083] In this embodiment, the laser welding machine 001 realizes the control of several driving mechanisms on the corresponding structural components through the mutually cooperating guide rails and sliders. Specifically, the control of the first driving mechanism 5 on the first bearing platform 4 is realized by setting a first guide rail and a first slider (not shown in the figure). Specifically, the first guide rail is provided on the first bearing platform 4, the first guide rail extends along the first horizontal direction, and the first slider is connected to the first bearing platform 4 to enable the first bearing platform 4 to reciprocate along the extension direction of the first guide rail.

[0084] At the same time, the control of the second driving mechanism 7 on the second bearing platform 6 is realized by setting a second guide rail and a second slider (not shown in the figure). The second guide rail is provided on the bottom platform 15, the second guide rail extends along the second horizontal direction, and the second slider is connected to the second bearing platform 6 to enable the second bearing platform 6 to reciprocate along the extension direction of the second guide rail.

[0085] In addition, the control of the third driving mechanism 9 on the locking interface 8 is realized by setting a third guide rail and a third slider (not shown in the figure). The third guide rail is provided on the column 2, the third guide rail extends along the vertical direction, and the third slider is connected to the locking interface 8 to enable the locking interface 8 to reciprocate along the extension direction of the third guide rail. Specifically, the galvanometer carrier 3, the first bearing platform 4, and the second bearing platform 6 are arranged in sequence from top to bottom.

[0086] The provided first guide rail, first slider, second guide rail, second slider, third guide rail, and third slider can make the first bearing platform 4, the second bearing platform 6, and the locking interface 8 move more stably along the set direction, without deviating from the set movement direction and moving more smoothly.

[0087] Of course, in other embodiments, the slide rail and slider may not be provided, and the driving mechanism uses transmission components such as lead screws to reciprocate the corresponding structure.

[0088] In this embodiment, as Figure 3 and as shown in 4 and Figure 5 As shown, the bottom platform 15 of the laser welding machine 001 is rectangular, and the galvanometer carrier 3 is also rectangular. The second horizontal direction is parallel to the extension direction of the long side of the bottom platform 15, and at the same time, the second horizontal direction is the X-axis direction. By setting the first horizontal direction to be parallel to the extension direction of the long side of the bottom platform 15, the galvanometer carrier 3 has a greater degree of freedom of movement on the bottom platform 15, that is, the space utilization rate of the bottom platform 15 is improved, the set range of the clamping part is expanded, thereby increasing the upper limit of the number of clamping parts, and further improving the production line efficiency.

[0089] In this embodiment, the clamping parts are centrally arranged on the galvanometer carrier 3, and eight clamping parts are evenly arranged on the galvanometer carrier 3 (the position of the galvanometer 11 in the figure is only a schematic drawing). And the clamping parts in this embodiment are rectangular, and the sides of the clamping parts are parallel to the sides of the galvanometer carrier 3. The centrally arranged clamping parts on the galvanometer carrier 3 are more beautiful. By setting the clamping parts to be rectangular and the sides of the clamping parts to be parallel to the sides of the galvanometer carrier 3, and the clamping parts are evenly arranged on the galvanometer carrier 3, the number of clamping parts arranged on the galvanometer carrier 3 can be maximized, the space utilization rate of the galvanometer carrier 3 is improved, and the production efficiency is improved.

[0090] In this embodiment, the power sources of the first driving mechanism 5, the second driving mechanism 7, and the third driving mechanism 9 are all motors. The scheme of using a motor as the power source to achieve reciprocating movement control has a simple structure, is convenient to install, and is also convenient to maintain.

[0091] Of course, in other embodiments, the driving mechanism may also be other structural forms that can drive the connected components to reciprocate, such as setting the driving mechanism as a cylinder or the like.

[0092] The second horizontal direction is the extension direction of the long side of the bottom platform 15, and the second horizontal direction is the extension direction of the short side of the bottom platform 15, that is, the included angle between the first horizontal direction and the second horizontal direction is equal to 90°. By setting the first horizontal direction and the second horizontal direction to an included angle equal to 90°, that is, the first horizontal direction and the second horizontal direction are perpendicular, and respectively controlling the movement of the galvanometer carrier 3 on the X-axis and Y-axis, the algorithm is simpler when calculating the position coordinates.

[0093] Of course, in other embodiments, as long as the first horizontal direction and the second horizontal direction are different, that is, the first horizontal direction is not parallel to the second horizontal direction, as long as the first horizontal direction is different from the second horizontal direction, the purpose of making the galvanometer carrier 3 move as required along the X-axis and Y-axis can be achieved by the combined motion control of the first driving mechanism 5 and the second driving mechanism 7. Of course, it is more preferable that the included angle between the first horizontal direction and the second horizontal direction is as large as possible. More preferably, the included angle between the first horizontal direction and the second horizontal direction should be greater than 45°. Even more preferably, the included angle between the first horizontal direction and the second horizontal direction should be 90° (i.e., the angle formed by the first driving mechanism 5 and the second driving mechanism 7 in this embodiment).

[0094] Embodiment 2

[0095] As Figures 8-9 shown, this embodiment provides a galvanometer 17, which includes a carrier base 171 and a rotating base 172, and the carrier base 171 and the rotating base 172 are connected by welding. By connecting the carrier base 171 and the rotating base 172 by welding, there is no need to provide screw holes for screwing to fix the carrier base 171 and the rotating base 172, reducing the volume of the carrier base 171 and the rotating base 172, and thus reducing the volume of the entire galvanometer 17.

[0096] Specifically, in this embodiment, the galvanometer has a carrier base 171, a rotating base 172, a base 173, and an optical component 174. The rotating base 172, the carrier base 171, and the base 173 are sequentially arranged in contact. The carrier base has a first hollow portion for accommodating the optical component, and the rotating base 172 has a second hollow portion 1721 for exposing the optical component 174, that is, the rotating base 172 does not block the optical component 174. The optical component of the galvanometer has a first rotating shaft P and a second rotating shaft Q extending in different directions. The number of the first connection positions M is two, and the two first connection positions M are respectively arranged on both sides of the first hollow portion and are symmetrically arranged with respect to the first rotating shaft P. The number of the second connection positions N is also two, and the two second connection positions N are symmetrically arranged with respect to the second rotating shaft Q. The connection methods at the first connection positions M and the second connection positions N are both welding connections. By also welding the base 173 and the rotating base 172, there is no need to provide screw holes for screwing to fix the base 173 and the rotating base 172, and there is no nut occupying space in the entire galvanometer 17, further reducing the volume of the galvanometer 17.

[0097] In this embodiment, the welding methods at the first connection positions M and the second connection positions N are both full welding. In other embodiments, the welding method at the first connection position M can be spot welding, and the welding method at the second connection position N can also be spot welding.

[0098] In this embodiment, the galvanometer has a first rotating shaft and a second rotating shaft in different directions. Therefore, the galvanometer has a first connection position M and a second connection position N, and both the first connection position M and the second connection position N are fixed by means of welding.

[0099] In other embodiments, if the optical component 174 only needs to rotate around one rotating shaft, it only needs to weld the bearing seat 171 and the rotating seat 172 on both sides of the bearing seat 171 with the first rotating shaft P as the center to the rotating seat 172.

[0100] The connection and fixing relationship among the bearing seat 171, the rotating seat 172 and the base 173 and the relationship with the rotation of the optical component 174 are the content of the prior art and will not be elaborated here.

[0101] Although the specific implementation manners of the present utility model have been described above, those skilled in the art should understand that this is only an example, and the protection scope of the present utility model is defined by the appended claims. Without departing from the principle and essence of the present utility model, those skilled in the art can make various changes or modifications to these implementation manners, but these changes and modifications all fall within the protection scope of the present utility model.
