Description

Technical Field

[0001] The utility model relates to the field of assembly technology of laser radar, and in particular to a lens mounting device for mounting the lens of the laser radar. Background Art

[0002] During the LiDAR production process, a key control parameter is the angle between the laser's emitted light beam and the horizontal plane, known as the pitch angle. The current control method involves pre-placing a collimating lens into a bracket hole, manually attaching the circuit board containing the laser to the bracket, and then, in the next step, manually observing the position of the laser's beam spot using an infrared camera. If the beam spot falls in the correct position, the product continues to be processed; otherwise, the circuit board is disassembled and reattached. This current manual operation is inefficient and subject to significant errors. Utility Model Content

[0020] To further illustrate various embodiments, the present invention is provided with accompanying drawings. These drawings form part of the disclosure of this invention and are primarily used to illustrate the embodiments and, in conjunction with the relevant description in the specification, to explain the operating principles of the embodiments. By referring to these drawings, those skilled in the art will understand other possible implementations and the advantages of this invention. The components in the figures are not drawn to scale, and similar reference numerals are generally used to represent similar components.

[0021] In the description of the present invention, terms such as "up", "down", "left", "right", "front", and "back" and other orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings and are only for the convenience of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, they should not be understood as limiting the present invention.

[0022] The present invention will now be further described with reference to the accompanying drawings and specific implementation methods.

[0023] Reference Figures 1 to 3 As shown, this embodiment provides a lens mounting device, comprising: a processor 28, a first tray mechanism 21, a pick-and-place mechanism 10, a glue dispensing mechanism 24, a UV curing mechanism 25, a light spot reflector 27, and a visual mechanism 26. The first tray mechanism 21 is used to place a bracket 1. Specifically, the bracket 1 is part of a laser radar, on which a circuit board containing a laser is fixed. The pick-and-place mechanism 10 is movable to transfer the lens to the bracket 1 on the first tray mechanism 21. The light spot reflector 27 is disposed on top of the first tray mechanism 21. The collection end of the visual mechanism 26 is aligned with the light spot reflector 27. The output end of the visual mechanism 26 is connected to the processor 28. The output end of the processor 28 is connected to the pick-and-place mechanism 10, the glue dispensing mechanism 24, and the UV curing mechanism 25. The glue dispensing mechanism 24 and the UV curing mechanism 25 both correspond to the first tray mechanism 21, so as to dispense glue and cure the lens on the bracket 1, respectively.

[0024] Its operating principle is as follows: During assembly, the pick-and-place mechanism 10 transfers the lens to the bracket 1 on the first tray mechanism 21; the laser light on bracket 1 passes through the lens and projects onto the top spot reflector 27, forming a light spot on the spot reflector 27; the vision mechanism 26 collects image information from the spot reflector 27 projecting the laser light and transmits it to the processor 28; the processor 28 processes the information and determines whether the light spot is in the specified position. If not, it controls the pick-and-place mechanism 10 to adjust until it is in the specified position; after the position adjustment is completed, the processor 28 controls the dispensing mechanism 24 and the UV curing mechanism 25 to dispense glue and cure, respectively, to achieve precise assembly. Compared with manual operation, this greatly improves installation efficiency and accuracy.

[0025] Furthermore, in this embodiment, the pick-and-place mechanism 10 includes a Y-axis translation mechanism 11, a Z-axis lifting mechanism 12, and a vacuum nozzle 13. The Z-axis lifting mechanism 12 is mounted on the drive end of the Y-axis translation mechanism 11, and the vacuum nozzle 13 is mounted on the drive end of the Z-axis lifting mechanism 12. Thus, the vacuum nozzle 13 picks and places the lens by sucking and breaking the vacuum. The Y-axis translation mechanism 11 drives the Z-axis lifting mechanism 12 and the vacuum nozzle 13 to move along the Y-axis direction (left-right in this embodiment), and the Z-axis lifting mechanism 12 drives the vacuum nozzle 13 to move along the Z-axis direction (up-down in this embodiment). The first tray mechanism 21 is located within the travel range of the Y-axis translation mechanism 11 and can move along the X-axis direction (forward-backward in this embodiment), ensuring that the pick-and-place mechanism 10 can place the lens on the bracket 1 on the first tray mechanism 21. Furthermore, the first tray mechanism 21 can move along the X-axis direction, capable of shifting the brackets on it, so that the multiple brackets on the first tray mechanism 21 correspond one-to-one to the installation stations. The output end of the processor 28 is also connected to the first tray mechanism 21, that is, the movement of the first tray mechanism 21 is controlled by the processor 28. For example, after the current bracket 1 is assembled, the processor 28 controls the first tray mechanism 21 to move forward a preset distance so that the next bracket 1 corresponds to the installation station.

[0026] Furthermore, the Y-axis translation mechanism 11 can be implemented by an electric push rod or a motor screw pair arranged along the Y-axis direction; the Z-axis lifting mechanism 12 can be implemented by a lifting cylinder or a motor, a gear and a rack to achieve lifting drive; the first pallet mechanism 21 can be implemented by an electric push rod or a motor screw pair arranged along the X-axis direction and a pallet fixed thereon, and so on.

[0027] Specifically, the pick-and-place mechanism 10 adopts the above structure, which is easy to implement and has low cost. Of course, in other embodiments, a robotic arm or the like can also be used to implement the pick-and-place mechanism.

[0028] The dispensing mechanism 24 is provided in two groups, one on each side of the first tray mechanism 21 in the Y-axis direction. The dispensing mechanisms 24 on both sides perform dispensing, ensuring more complete and uniform dispensing without obstructing laser projection. Specifically, the dispensing mechanism 24 employs an existing structure and will not be described in detail here.

[0029] Similarly, the UV curing mechanism 25 is also provided with two groups, one on each side of the first tray mechanism 21 in the Y-axis direction; curing is more uniform and sufficient, and does not hinder the projection of the laser. Specifically, the UV curing mechanism 25 adopts an existing mechanism, such as a UV lamp.

[0030] In this embodiment, the UV curing mechanism 25 is located above the glue dispensing mechanism 24 and does not interfere with the operation of the glue dispensing mechanism 24 .

[0031] Further preferably, the system further includes a second tray mechanism 22 that is movable along the X-axis for placing lenses. The second tray mechanism 22 is arranged side by side with the first tray mechanism 21 along the Y-axis and both are within the travel range of the Y-axis translation mechanism 11. The output of the processor 28 is also connected to the second tray mechanism 22. This arrangement enables the pick-and-place mechanism 10 to remove a lens from the second tray mechanism 22 and transfer it to the bracket 1 on the first tray mechanism 21. Simultaneously, when the next lens needs to be removed, the processor 28 controls the movement of the second tray mechanism 22 to position the next lens for removal. More specifically, the structure of the second tray mechanism 22 is identical to that of the first tray mechanism 21 and will not be described in detail here.

[0032] More preferably, a calibration mechanism 23 is included. The calibration mechanism 23 is located within the travel range of the Y-axis translation mechanism 11 and is used to calibrate the lens being picked up. That is, after the pick-up and placement mechanism 11 picks up the lens, it is placed in the calibration mechanism 23 for calibration before being transferred to the bracket 1, which improves accuracy.

[0033] Furthermore, the calibration mechanism 23 includes a clamping cylinder and two clamping arms mounted on the clamping cylinder; the two clamping arms form a positioning space that matches the lens's shape; the output of the processor 28 is also connected to the clamping cylinder. During calibration, the pick-and-place mechanism 10 places the lens in the corresponding position. The processor 28 then controls the clamping cylinder to clamp the lens, bringing the two clamping arms closer together to calibrate the lens' position. The clamping cylinder then opens, and the pick-and-place mechanism 10 transfers the lens to the bracket 1. This approach offers a simple structure and is easy to implement. Of course, calibration can be performed without the calibration mechanism 23 in other embodiments.

[0034] Furthermore, the machine 30 is further included. The machine 30 has a working platform 31. The processor 28, the first tray mechanism 21, the second tray mechanism 22, the calibration mechanism 23, the pick-and-place mechanism 10, the glue dispensing mechanism 24, the UV curing mechanism 25 and the visual mechanism 26 are all arranged on the machine 30, and the first tray mechanism 21, the second tray mechanism 22, the calibration mechanism 23, the pick-and-place mechanism 10, the glue dispensing mechanism 24 and the UV curing mechanism 25 are arranged on the working platform 31 of the machine. Figure 1 and 2 As shown, the first tray mechanism 21, the second tray mechanism 22, and the calibration mechanism 23 are arranged sequentially from left to right. A gantry 32 is provided on the work platform 31, and the pick-and-place mechanism 10 is mounted on the gantry 32. The vision mechanism 26 is also fixed to one side of the gantry 32. This arrangement forms a complete structure for the lens mounting device, facilitating transportation after assembly.

[0035] Furthermore, in this embodiment, the above-mentioned visual mechanism 26 and processor 28 are also existing technologies. For example, the visual mechanism 26 is implemented by an industrial camera to collect image information of the light spot reflection plate 27. The processor 28 can adopt a PLC processor in the existing technology. The technology of processing images by the PLC processor to determine whether it meets the preset requirements has long been mastered and implemented by technical personnel in this field, and will not be described in detail here.

[0036] Although the present invention has been specifically shown and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes can be made to the form and details of the present invention without departing from the spirit and scope of the present invention as defined by the appended claims, and all of these changes are within the scope of protection of the present invention.
