Description

Technical Field

[0001] This invention belongs to the field of solar thermal power generation technology, and particularly relates to a mirror frame positioning and fixing device. Background Technology

[0002] In tower solar thermal power generation projects, heliostats function to concentrate sunlight onto the receiver and are the core component of the project. The precision of the heliostat directly determines the focusing efficiency of sunlight, thus affecting the overall power generation rate of the solar field. The assembly quality of the heliostat is a crucial aspect of its precision.

[0003] The assembly of a heliostat includes the positioning and fixing of the frame. Currently, this step is carried out by using clamps to hold the main beam and manual adjustment for the rest. Therefore, the frame needs to be repeatedly adjusted manually during the assembly process, which can lead to problems such as low assembly efficiency and inability to guarantee assembly quality. Summary of the Invention

[0004] The purpose of this invention is to provide a frame positioning and fixing device to solve the problem of low assembly efficiency in the frame positioning and fixing process in the prior art.

[0005] The technical solution of this invention is as follows:

[0006] A frame positioning and fixing device, comprising:

[0007] A first detection unit and a second detection unit, wherein the first detection unit is used to detect the height and inclination of the main beam, and the second detection unit is used to detect the axial position of the main beam;

[0008] A main beam positioning and fixing assembly, used for positioning and fixing the main beam, includes:

[0009] The positioning block is provided with a main beam placement groove that fits the shape of the main beam for placing the main beam. The length direction of the main beam placement groove is the same as the axial direction of the main beam.

[0010] Positioning pins are provided on both sides of the two side walls of the main beam placement groove. After the positioning pin passes through the process hole on the main beam, its two ends are respectively installed in the positioning pin installation position.

[0011] The clamping element moves synchronously with the positioning block to clamp the main beam;

[0012] The main beam drive unit is connected to the positioning block and the clamping member respectively. The main beam drive unit is used to cooperate with the first detection unit to drive the positioning block and the clamping member to rise and fall to reach a specified height. The main beam drive unit is also used to cooperate with the second detection unit to drive the positioning block and the clamping member to move along the axial direction of the main beam to reach a specified position.

[0013] Sub-beam positioning and fixing components are used for positioning and fixing the sub-beams.

[0014] In one embodiment of the eyeglass frame positioning and fixing device, the positioning pin mounting position is a positioning pin placement groove provided on the upper surface of the positioning block, and the two ends of the positioning pin extend out of the process hole and are respectively placed in the two positioning pin placement grooves.

[0015] In one embodiment of the eyeglass frame positioning and fixing device, the main beam driving part includes:

[0016] An axial drive component, the output end of which is connected to the positioning block and the clamping block respectively, is used to synchronously drive the positioning block and the clamping component to move along the axial direction of the main beam;

[0017] The height drive component has its output end connected to the fixed end of the axial drive component, and is used to drive the axial drive component to rise and fall, so as to drive the positioning block and the clamping component to rise and fall synchronously.

[0018] In one embodiment of the eyeglass frame positioning and fixing device, the first detection unit is a visual detection system used to detect the height of the mark set on the main beam to obtain the height of the main beam.

[0019] In one embodiment of the eyeglass frame positioning and fixing device, the main beam is a circular tube structure, and the center of the tube openings at both ends of the main beam is the mark;

[0020] The main beam is equipped with detection structures of the vision detection system at both ends along its axial direction, which are used to detect the height of the center of the pipe openings at both ends of the main beam.

[0021] In one embodiment of the eyeglass frame positioning and fixing device, the second detection unit includes a distance sensor. The distance sensor is provided on at least one side of the main beam along its axial direction. The distance sensor is used to detect the distance between itself and the main beam or the distance between itself and any part that is fixed in a relative position to the main beam.

[0022] In one embodiment of the eyeglass frame positioning and fixing device, the secondary beam positioning and fixing component includes a secondary beam drive and a clamp, wherein when the clamp is opened, the opening is aligned with one end of the secondary beam;

[0023] The gripper or the part connected to the gripper has a positioning part for placing the sub-beam. The positioning part is located below the sub-beam and abuts against the lower surface of the sub-beam to achieve positioning of the height of the sub-beam.

[0024] The output end of the sub-beam drive is connected to the gripper, and is used to drive the gripper to move along the axial direction of the sub-beam until the gripper moves to a preset position. After the gripper moves to the preset position, it clamps the sub-beam to position the sub-beam.

[0025] In one embodiment of the eyeglass frame positioning and fixing device, the clamp is a centering clamp, which includes two claws that move toward each other to clamp the sub-beam.

[0026] In one embodiment of the eyeglass frame positioning and fixing device, the sub-beam positioning and fixing assembly further includes a slide table, the slide table being fixedly connected to the output end of the sub-beam drive member, the gripper being connected to the slide table, and a wedge block being connected to the side of the slide table facing the sub-beam, the wedge block being provided with the positioning part.

[0027] In one embodiment of the eyeglass frame positioning and fixing device, the upper surface of the wedge is an inclined surface, the height of the inclined surface increases along the axial direction of the sub-beam toward the slide table, and the highest point of the inclined surface is the positioning part.

[0028] Because of the above technical solutions, this invention has the following advantages and positive effects compared with the prior art:

[0029] In use, the eyeglass frame positioning and fixing device provided by this invention first places the eyeglass frame on the device, and then places the main beam on the main beam placement groove. Since the shape of the main beam placement groove matches the shape of the main beam, the position of the main beam in the width direction can be positioned. Then, the first detection unit, in conjunction with the main beam driving unit, adjusts the main beam to the required height. Next, the positioning pin is inserted into the process hole on the main beam and installed in the positioning pin mounting position to prevent the eyeglass frame from tipping over and to initially position the rotation of the main beam. Then, the second detection unit, in conjunction with the main beam driving unit, adjusts and positions the main beam in its axial direction. Finally, the secondary beam is positioned and fixed by the secondary beam positioning and fixing assembly, thereby achieving the final positioning of the rotation of the main beam. After the positioning of the main beam's width direction position, height, axial position, and rotation is completed, the clamping member clamps and fixes the main beam.

[0030] Compared to existing technologies that rely on repeated manual adjustments for frame positioning, this device offers a convenient, quick, and highly accurate solution for positioning and fixing the main beam and secondary beams within the frame. Therefore, this device solves the problem of low assembly efficiency in the existing frame positioning and fixing process, while also achieving higher precision and assembly quality.

Detailed Implementation

[0041] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of the present invention. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0042] To keep the drawings concise, only the parts relevant to the invention are shown schematically in each figure, and they do not represent the actual structure of the product. Furthermore, for ease of understanding, in some figures, only one of components with the same structure or function is shown schematically, or only one is labeled. In this document, "one" can mean not only "only one" but also "more than one".

[0043] See Figures 1 to 7This embodiment provides a frame positioning and fixing device, including a first detection unit, a second detection unit, a main beam positioning and fixing assembly 1, and a secondary beam positioning and fixing assembly 2. The first detection unit is used to detect the height of the main beam 51, and the second detection unit is used to detect the axial position of the main beam 51. The secondary beam positioning and fixing assembly 2 is used for positioning and fixing the secondary beam 52.

[0044] The main beam positioning and fixing assembly 1 is used for positioning and fixing the main beam 51, and includes a positioning block 11, positioning pins 16, clamping components, and a main beam drive unit. The positioning block 11 has a main beam placement groove 111 that fits the shape of the main beam 51 for placing the main beam 51. The length direction of the main beam placement groove 111 is the same as the axial direction of the main beam 51. Positioning pin mounting positions are provided on both sides of the two side walls of the main beam placement groove 111. The positioning pins 16 pass through the process holes on the main beam 51, and their two ends are respectively installed in the positioning pin mounting positions. The clamping components move synchronously with the positioning block 11 to drive and clamp the main beam 51. The main beam drive unit is connected to the positioning block 11 and the clamping components respectively. The main beam drive unit is used to cooperate with the first detection unit to drive the positioning block 11 and the clamping components to rise and fall to a specified height. The main beam drive unit is also used to cooperate with the second detection unit to drive the positioning block 11 and the clamping components to move along the axial direction of the main beam 51 to reach a specified position.

[0045] This device enables convenient, quick, and high-precision positioning and fixing of the main beam 51 and secondary beam 52 in the eyeglass frame 5. The eyeglass frame 5 positioned and fixed by this device has the advantages of high assembly efficiency, high precision, and high assembly quality.

[0046] The structure of this embodiment will now be described. The eyeglass frame 5 includes a main beam 51, a secondary beam 52, a support beam 53, etc. The main beam 51 and the secondary beam 52 have been assembled and fixed before using the eyeglass frame positioning and fixing device provided by the present invention.

[0047] Multiple main beam positioning and fixing components 1 can be provided, arranged along the axial direction of the main beam 51. However, since the frame 5 is initially "supported" by placing the main beam 51 in the main beam placement groove 111 of the positioning block 11, at least two main beam positioning and fixing components 1 are provided. The main beam positioning and fixing device may include a support platform 15, and the main beam drive unit may be provided on the support platform 15. Specifically, the main beam drive unit includes an axial drive component 14 and a height drive component 13. The height drive component 13 is fixedly connected to the support platform 15, and its output end is connected to the fixed end of the axial drive component 14; the output end of the axial drive component 14 is connected to the positioning block 11 and the clamping component respectively. The axial drive component 14 is used to synchronously drive the positioning block 11 and the clamping component to move along the axial direction of the main beam 51, and the height drive component 13 is used to drive the axial drive component 14 to rise and fall, thereby driving the positioning block 11 and the clamping component to rise and fall synchronously. The structure of the height drive component 13 can be of many kinds, such as a servo motor plus a lifting structure, a cylinder drive, etc., and there is no specific limitation. The structure of the axial drive component 14 can also be varied, such as a servo motor with a lead screw and nut, or a cylinder drive, etc., and there are no specific limitations.

[0048] The main beam placement groove 111 on the positioning block 11 is designed according to the shape of the main beam 51. It is a through groove with a cross-section similar to a semi-circle. After the main beam 51 is placed in the main beam placement groove 111, it is fixed in place, so that the main beam 51 can only move along the axial direction or rotate around its own axis.

[0049] The rotation of the main beam 51 is restricted by the positioning pins 16 to prevent the entire frame 1 from tipping over; at the same time, it can also provide preliminary positioning of the rotation of the main beam 51. Specifically, in this embodiment, the positioning pin mounting position is a positioning pin placement groove 112 located on the upper surface of the positioning block 11, with one pin on each of the two side walls of the main beam placement groove 111, such as... Figure 4 As shown. The two ends of the positioning pin 16 extend out of the process holes and are placed in the two positioning pin placement slots 112 respectively. The positioning pin 16 prevents the main beam 51 from rotating, and thus provides initial positioning of the main beam 51's rotational degree. Besides the arrangement shown in this embodiment, the positioning pin mounting position can also be configured in other ways. For example, the positioning pin mounting position can be a through hole on the side wall of the main beam placement slot 111, with two through holes cooperating to form a through hole penetrating both side walls of the main beam placement slot 111. Therefore, the specific arrangement of the positioning pin mounting position is not limited in this invention.

[0050] The height of the main beam 51 is positioned by the first detection unit in conjunction with the height driving component 15. In this embodiment, the first detection unit can be a vision detection system; however, other methods can be used in other embodiments, and this is not a limitation. Marks are set on the main beam 51, and the vision detection system obtains the height of the main beam 51 by detecting the height of the marks on the main beam 51. Specifically, the main beam 51 adopts a circular tube structure, and the center of the tube openings at both ends of the main beam 51 is the mark; detection structures 3 of the vision detection system are respectively provided at both ends of the main beam 51 along its axial direction, used to detect the height of the center of the tube openings at both ends of the main beam 51. A mounting plate 17 can be connected to the support platform 15 closest to the end of the main beam 51, and the detection structure 3 of the vision detection system can be mounted on the mounting plate 17, such as... Figure 2 and Figure 3 As shown, the detection structure 3 can also be installed in other places, and there are no restrictions here. After the main beam 51 is placed on the main beam placement slot 111, the relative position of the main beam 51 and the positioning block 11 in terms of height is fixed. Then, the positioning block 11 is driven to rise and fall by the height drive component 13 in conjunction with the vision detection system, so that the main beam 51 reaches the required positioning height. The vision detection system detects the height of the center of the pipe openings at both ends of the main beam 51 in the axial direction, so that when it is adjusted with the height drive component 13, it can not only ensure the height position of the detection point (i.e., the mark) of the main beam 51, but also ensure the tilt of the entire main beam 51, thereby ensuring the height of every part of the main beam 51.

[0051] The second detection unit, in conjunction with the axial drive component 14, positions the main beam 51 axially. In this embodiment, the second detection unit can be a distance sensor 4; however, other methods can be used in other embodiments, and this is not a limitation. The distance sensor 4 can be mounted on the mounting plate 17, similar to the detection structure 3 of the vision inspection system, to detect the distance between itself and the main beam 51, or the distance between itself and any component fixed in a relative position to the main beam 51, thereby adjusting the axial position of the main beam 51 in conjunction with the axial drive component 14. The distance sensor 4 is provided on at least one side of the main beam 51 along its axial direction; more preferably, it is provided on both sides of the main beam 51 along its axial direction. The distance sensor 4 can detect the distance to the end of the main beam 51, the distance to the nearest support beam 53, etc., and this is not limited.

[0052] The main beam 51 is clamped and fixed by a clamping device. Specifically, in this embodiment, the clamping device can be a clamp 12. The clamp 12 is initially in an open (or loose) state, and when it is necessary to clamp and fix the main beam 51, it is closed to clamp the main beam 51.

[0053] Each end of the sub-beam 52 is provided with a sub-beam positioning and fixing component 2, forming a pair. The sub-beam positioning and fixing components 2 are installed in pairs. Preferably, each end of each sub-beam 52 is provided with a sub-beam positioning and fixing component 2, but in actual use, it is not necessary to provide a pair of sub-beam positioning and fixing components 2 for each sub-beam 52. The sub-beam positioning and fixing component 2 includes a sub-beam drive member 22, a gripper, and a support column 25. The support column 25 is fixed to the ground, and the sub-beam drive member 22 is fixed to the top of the support column 25. The output end of the sub-beam drive member 22 is connected to a slide 23. The specific structure of the sub-beam drive member 22 is not limited; for example, a cylinder can be used. The gripper is fixed to the slide 23, and the sub-beam drive member 22 drives the slide 23 to move axially along the sub-beam 52, thereby driving the gripper to move axially along the sub-beam 52. When the gripper opens, its opening is aligned with one end of the sub-beam 52. When the sub-beam drive unit 22 drives the slide table 23, it moves the gripper to the preset position, and then the gripper clamps the sub-beam 52.

[0054] The gripper can be a centering gripper 21, which includes two claws. When the gripper moves to a preset position, the secondary beam 52 is located between the two claws. After the gripper moves to the preset position, the two centering grippers 21 move towards each other until they clamp the secondary beam 52, thus positioning the secondary beam 52. Of course, in other embodiments, the gripper can also adopt other structures, and there is no limitation on this.

[0055] A positioning part is provided on the gripper or the part connected to the gripper. The positioning part is located below the sub-beam 52 and the lower surface of the sub-beam 52 abuts against the positioning part, thereby achieving the positioning of the height of the sub-beam 52. When the sub-beam drive member 22 drives the gripper and other parts to move to the preset position, the position where the positioning part abuts against the sub-beam 52 is the position of the lower surface of the sub-beam 52 after precise positioning. After the positioning pin 16 performs preliminary positioning of the rotation of the main beam 51, since the positioning pin 16 is close to the axis of the main beam 51, the small error that may occur during the rotation positioning may be reflected at the end of the sub-beam 52, and the height difference between the two ends of the sub-beam 52 may be large (under normal design, the heights of the two ends of the sub-beam 52 should be the same). Therefore, the heights of the two ends of the sub-beam 52 are positioned to achieve the final positioning of the rotation of the main beam 51.

[0056] Specifically in this embodiment, such as Figure 7As shown, a wedge 24 can be connected to the side of the slide 23 facing the sub-beam 52. The upper surface of the wedge 24 is an inclined surface, and the height of the inclined surface increases along the axial direction of the sub-beam 52 towards the slide 23. The highest point of the inclined surface is the positioning part. Of course, in other embodiments, the positioning part can also be set on other structures, such as a surface on the gripper, which is not limited here. After the positioning pin 16 initially positions the rotation of the main beam, the sub-beam 52 may have a slight tilt at one end and a slight droop at the other end (i.e., the heights of the two ends are different). Thus, when the sub-beam drive 22 drives the gripper, slide 23, wedge 24 and other parts to move along the axial direction of the sub-beam 52, the positioning can be adjusted by means of the inclined surface on the wedge 24; for example, see Figure 7 When the sub-beam 52 is driven by the sub-beam drive member 22 to move the wedge block 24, the lower end of the sub-beam 52 can be adjusted to the height required for final positioning by means of the inclined surface on the wedge block 24, while the raised end will slowly rotate downward until the lower surface abuts against the corresponding positioning part.

[0057] In use, the eyeglass frame 5 is first placed on the device. The main beam 51 on the eyeglass frame 5 is placed on the open clamp 12 and the main beam placement groove 111. Since the shape of the main beam placement groove 111 matches the shape of the main beam 51, the position of the main beam 51 in the width direction can be positioned. Then, the detection structure 3 of the vision inspection system takes pictures of the end openings of the main beam 51 to determine the height of both ends of the main beam 51. After the height of both ends of the main beam 51 is determined, the height position of the main beam 51 is adjusted by the height drive component 13. After the height position is adjusted, the positioning pin 16 is inserted into the process hole on the main beam 51 and placed on the positioning pin placement groove 112 to prevent the eyeglass frame 5 from tipping over and to initially position the rotation of the main beam 51. Then, the distance sensor 4 measures the distance between itself and the nearest support, and the axial position of the main beam 51 is adjusted by the axial drive component 14 to achieve precise positioning of the axial position of the main beam 51. Then, the secondary beam drive component 22 drives the gripper to move along the axial direction of the secondary beam 52. The final positioning is achieved by the rotation of the main beam 51 via the inclined surface on the wedge block 24. Once the gripper reaches the preset position, it clamps the secondary beam 52, thus achieving precise positioning and fixation of the secondary beam 52. At this point, precise positioning of the main beam 51 in the width direction, height, axial position, and rotation is completed. Then, the clamp 12 clamps the main beam 51, thus fixing it in place.

[0058] The eyeglass frame positioning and fixing device provided by the present invention can achieve fully automatic (except for the step of inserting positioning pin 16) and highly accurate positioning, which improves the positioning efficiency and accuracy of eyeglass frame 5, reduces the time for repeated adjustment of main beam 51, and reduces the use of labor.

Even if various changes are made to the present invention, if these changes fall within the scope of the claims of the present invention and their equivalents, they shall still fall within the protection scope of the present invention.
