[0027] The utility model provides a collimation device and an optical path debugging system. Figures 1 to 4 A specific embodiment of a collimation device provided by the utility model.
[0028] like Figure 1 , Figure 2 and Figure 4 As shown, an embodiment of the utility model provides a collimation device 100, including a mounting seat 1 and at least two collimation parts 2 spaced apart in the axial direction of the mounting seat 1, the mounting seat 1 is provided with a light-transmitting hole 11 in the axial direction for laser to pass through, the two collimation parts 2 are arranged corresponding to the light-transmitting hole 11, and the central part of each collimation part 2 is provided with a collimation hole 21 for the center of the laser spot to pass through.
[0029] In the utility model, the mounting seat 1 is provided with a light-transmitting hole 11 in its axial direction, and at least two collimating parts 2 are arranged at intervals in the axial direction of the mounting seat 1 corresponding to the position of the light-transmitting hole 11, and a collimating hole 21 is opened at the center position of each collimating part 2. When the collimating device 100 is used to detect the laser, the operator adjusts the position of the collimating device 100 so that the laser passes through the light-transmitting hole 11. When the center of the laser spot can pass through the collimating holes 21 of the two collimating parts 2 and hit the part to be processed, it means that the laser acts vertically on the part to be processed. At this time, the laser processes the part to be processed, ensuring the processing effect.
[0030] It should be noted that, the greater the distance between the collimating parts 2 arranged at intervals, the greater the number of the collimating parts 2, and the higher the detection accuracy of the collimating device 100.
[0031] The specific number and spacing of the collimating parts 2 are not limited, as long as the accuracy of the collimating device 100 when detecting the verticality of the laser can meet the requirements. For example, in some embodiments, Figure 1and Figure 2 As shown, the mounting seat 1 includes a mounting portion 12 and a distance adjustment device 13, one end of the distance adjustment device 13 is connected to the mounting portion 12 and extends in the axial direction of the mounting seat 1, and each of the collimating portions 2 is respectively arranged at both ends of the distance adjustment device 13. In this way, the collimating device 100 is connected to the device to be collimated through the mounting portion, and two collimating portions 2 are provided, which are respectively arranged at both ends of the distance adjustment device 13. The distance between the two collimating portions 2 can be adjusted by the distance adjustment device 13. The farther the distance between the two collimating portions 2 is, the higher the detection accuracy of the collimating device 100 is. However, due to the distance limit between the laser head and the part to be processed, and the need to reserve space for the operator to move the part to be processed, the distance between the two collimating portions 2 cannot be increased indefinitely, and needs to be adjusted in combination with the actual detection conditions.
[0032] Since each of the collimating parts 2 is respectively arranged at the two ends of the distance adjusting device 13, the collimating part 2 can be directly bonded to the ends of the distance adjusting device 13 by glue, or can be extended from the ends into the distance adjusting device 13 to complete the connection. In some embodiments, Figure 3 As shown, the inner walls of both ends of the distance adjustment device 13 are provided with limit bosses 131 protruding inwardly for the collimating part 2 to be placed. In this way, compared with directly gluing, on the one hand, the collimating part 2 is placed in the distance adjustment device 13 to protect the collimating part 2, and on the other hand, it is convenient for operators to disassemble and adjust the position of the collimating part 2.
[0033] It should be noted that the outer diameter of the collimating portion 2 is slightly smaller than the inner diameter of the distance adjusting device 13 , and larger than the inner diameter of the limiting boss 131 .
[0034] Furthermore, in order to better fix the collimating portion 2 in the distance adjusting device 13, in some embodiments, as Figure 1 and Figure 2 As shown, the collimation device 100 further includes two positioning parts 3, each of which is respectively arranged at the two ends of the distance adjustment device 13, and the positioning parts 3 can extend into the distance adjustment device 13, and cooperate with the limiting boss 131 to press the collimation part 2. In this way, the collimation part 2 is pressed against the limiting boss 131 by the positioning parts 3, so as to prevent the collimation part 2 from moving when the collimation device 100 detects the verticality of the laser, causing the position of the collimation hole 21 to be offset, thereby affecting the detection result.
[0035] The specific structure of the distance adjustment device 13 is not limited, as long as the distance adjustment device 13 can adjust the distance between the collimating parts 2. For example, in some embodiments, Figure 1 and Figure 2 As shown, the distance adjustment device 13 includes a plurality of connection structures 132, each of which extends along the axial direction of the mounting seat 1 and is connected end to end in sequence. The operator can adjust the distance between the collimating parts 2 by increasing or decreasing the number of the connection structures 132, and since the collimating parts 2 can be provided at both ends of the connection structures 132, the collimating parts 2 are not only provided at the two ends of the distance adjustment device 13, but also at the connection of two adjacent connection structures 132. The operator can increase the number of the collimating parts 2 by increasing the number of the connection structures 132, so as to improve the detection accuracy of the collimating device 100.
[0036] Furthermore, in some embodiments, Figure 3 As shown, the connection structure 132 includes a main body 132a and a connection part 132b, the inner diameter of the main body 132a is larger than the outer diameter of the connection part 132b, and the main body 132a and the connection part 132b are coaxially connected, and the connection part 132b can extend into the main body 132a of another connection structure 132 and be connected to the main body 132a. Since the connection part 132b can extend into the main body 132a of another connection structure 132, and the main body 132a and the connection part 132b are coaxially connected, on the one hand, the connection is more stable, ensuring the coaxial connection between the connection structures 132, and on the other hand, the connection part 132b can extend into and press the collimating part 2 into the main body 132a of another connection structure 132, reducing the parts for fixing the collimating part 2 and saving the production cost and assembly cost.
[0037] Specifically, the connection portion 132b may be connected to the main body portion 132a of the other connection structure 132 by means of threads or glue, or other connection methods known to those skilled in the art may be used.
[0038] Preferably, in some embodiments, the collimation device 100 further includes a snap-fit assembly, the snap-fit assembly includes a snap-fit portion and a matching portion, the snap-fit portion and the matching portion are detachably connected, and the connecting portion 132b is connected to the main body 132a of another connecting structure 132 through the snap-fit portion and the matching portion. In this arrangement, through the mutual cooperation between the snap-fit portion and the matching portion, the quick disassembly and assembly between the connecting portion 132b and the main body 132a of another connecting structure 132 is realized, and then the quick disassembly and assembly between multiple connecting structures 132 is realized, which greatly reduces the assembly time and cost of the collimation device 100.
[0039] Preferably, since the specific structure of the distance adjustment device 13 is not limited, as long as the distance adjustment device 13 can adjust the distance between the collimating parts 2, in some embodiments, the distance adjustment device 13 includes a lifting part, and the lifting part is movably arranged in the axial direction of the mounting seat 1. In this way, the distance between the collimating parts 2 can be adjusted by the lifting part, so that the distance can be infinitely adjusted, which better meets the operator's needs for distance adjustment.
[0040] Specifically, the lifting part includes one of a telescopic sleeve rod, a spiral telescopic rod and an electric push rod. At the same time, the lifting part may also include but is not limited to other components known to those skilled in the art that can achieve a telescopic function.
[0041] The specific shape of the collimating portion 2 is not limited, as long as the center of the laser spot can pass through the collimating hole 21. For example, in some embodiments, the collimating portion 2 includes four connecting bars, which extend from the central portion toward the circumferential side and are vertically arranged between adjacent connecting bars. In this arrangement, the four connecting bars form a cross, which can intuitively identify the position of the collimating hole 21. When the center of the laser spot deviates from the collimating hole 21, the deviation direction can be determined more quickly, helping the operator to adjust the center of the laser spot to the collimating hole 21 more quickly.
[0042] Furthermore, in some embodiments, the connecting strips of the two collimating parts 2 are staggered in the axial direction of the mounting seat 1 , so that an operator can observe the collimating parts 2 more clearly.
[0043] In addition, the utility model also proposes an optical path debugging system, including a laser head, a reflector and a collimation device 100 as described in any one of the above items, wherein the laser head, the reflector and the collimation device 100 are connected through a laser optical path, the reflector is movably arranged, and the collimation device 100 includes a mounting seat 1 and at least two collimation parts 2 arranged at intervals in the axial direction of the mounting seat 1, the mounting seat 1 is provided with a light-transmitting hole 11 in its axial direction for the laser to pass through, the two collimation parts 2 are arranged corresponding to the light-transmitting hole 11, and the central part of each collimation part 2 is provided with a collimation hole 21 for the center of the laser spot to pass through.
[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
