Description

Technical Field

[0001] The utility model relates to a clamping carrier, in particular to a clamping carrier suitable for assembling a 45-degree reflective sheet of an optical machine. Background Art

[0002] In the assembly process of the vehicle-mounted laser radar optical machine, the reflector is an important component. The main function of the reflector is to reflect the laser beam emitted by the laser radar back so as to receive and process the echo signal, thereby realizing the detection and ranging of the surrounding environment. In the existing tooling modules for assembling the reflector on the optical machine, two lenses with different angles are generally pasted at a single station, that is, the tooling needs to be driven by a motor to rotate to cooperate with the installation, and the rotating structure has poor stability when pressed, so it will cause low press-fitting accuracy. In addition, during the existing press-fitting, the press-fitting is only achieved by installing a pressing punch on the pressing sensor module. The reliability of press-fitting in this way is also poor. Utility Model Content

[0003] In order to solve the above technical problems, the purpose of the utility model is to provide a clamping carrier suitable for the assembly of 45° reflective sheets of optical machines. By changing the single-station installation of two lenses to the single-station installation of one lens, the motor rotation mechanism is eliminated, the accuracy of press-fitting is increased, and the reliability of press-fitting is further ensured by adding an independent pressure-maintaining mechanism on the carrier.

[0004] The utility model provides the following technical solutions:

[0005] A clamping carrier suitable for assembling a 45° reflective sheet of an optical machine, comprising a tooling base plate and a lens material table, a fixture carrier and a pressure-maintaining mechanism arranged in sequence on the tooling base plate. The reflective sheet to be assembled is placed on the lens material table. The fixture carrier is used to position a group of optical machines. The press-fitting position of the reflective sheet to be assembled on the optical machine is horizontally arranged. At this time, the manipulator can clamp the reflective sheet on the lens material table by adsorption and place it horizontally on the press-fitting position of the optical machine, which is convenient for reciprocating. The pressure-maintaining mechanism comprises an avoidance cylinder, an avoidance slide, a pressure-maintaining cylinder, a pressure-maintaining slide, a slide rail, a pressure-maintaining plate and a pressure-maintaining module. The avoidance cylinder is mounted on the tooling bottom plate, and a pressure-maintaining cylinder is mounted on the avoidance slide at its driving end through a stand, and a pressure-maintaining plate is mounted on the pressure-maintaining slide at the driving end of the pressure-maintaining cylinder through a set of slide rails, the sliding direction of the slide rails is the same as the driving direction of the pressure-maintaining cylinder, and the pressure-maintaining plate is used to horizontally approach the optical machine pressing position on the fixture carrier under the drive of the avoidance cylinder, and the pressure-maintaining plate is used to vertically press against the reflective sheet at the pressing position under the drive of the pressure-maintaining cylinder, and the pressure-maintaining module is connected to the pressure-maintaining plate to maintain a constant pressure when the pressure-maintaining plate vertically presses against the reflective sheet;

[0006] At this point, since only one set of optical machines is positioned on the fixture carrier, and the press-fitting position of the reflective sheet to be assembled with the optical machine is set horizontally, that is, this structural design realizes the elimination of the motor rotation mechanism by changing the single-station installation of two lenses to the single-station installation of one lens, thereby improving the stability during press-fitting and increasing the accuracy of press-fitting. At this time, an independent pressure-keeping mechanism can be added to the tooling bottom plate by being arranged on the opposite side of the lens material table, so that after the reflective sheet is placed in the press-fitting position, the reliability of press-fitting can be further ensured by the driving cooperation of the avoidance cylinder and the pressure-keeping cylinder, as well as the fixed-value pressing cooperation of the pressure-keeping plate.

[0007] Preferably, the pressure-maintaining module includes a substrate extending outward from both sides of the pressure-maintaining plate and a group of weights positioned on the substrate. When adjusting the pressure value of the pressure-maintaining plate, it is only necessary to determine the pressure value based on the deadweight of the pressure-maintaining plate and the weight after the weights are added or reduced. For the pressure-maintaining module using weights, a smaller precision error range can be ensured, but the force value range has certain limitations. Therefore, in actual production, it is suitable for situations where the pressure-maintaining value range is smaller.

[0008] Preferably, the pressure-maintaining module comprises a bottom block, a pressure sensor 1, a connecting block, bolts, and a spring. The bottom block is fixed on the pressure-maintaining slide, and a pressure sensor 1 is installed on it. The bottom of the connecting block is installed on the detection end of the pressure sensor 1, and two groups of bolts are also installed on it. The bolt guides pass through the edges of both sides of the pressure-maintaining plate, and a spring is sleeved on the outside, and the spring is pressed between the bolt end and the edge.

[0009] At this point, after the pressure-holding plate is moved to above the reflective sheet, the pressure-holding cylinder drives the pressure-holding slide to move a fixed distance, and the buffering compression of the spring can be used to achieve a certain pressure value of the pressure sensor. Using the pressure-holding module in this way can solve the problem of limited force range, but the pressure-holding accuracy for weak forces will also be slightly worse.

[0010] Preferably, the fixture carrier includes a gantry carrier, a support platform, a clamping cylinder and a clamping block. The gantry carrier is straddled on both sides of the avoidance cylinder, and a support platform is installed at an upper inclination angle of 45°. The clamping cylinder is installed on both sides of the gantry, and a clamping block positioned on the support platform is installed on the driving end of the clamping cylinder. The clamping block cooperates with the support platform to clamp the optical machine placed on the support platform.

[0011] Preferably, a group of pressure calibration jigs is also included, which are used to be loaded on the avoidance slide when calibrating the pressure, and a group of pressure sensor 2 is installed on the jig. Therefore, by placing a reflective sheet on the pressure sensor 2 and crimping the reflective sheet on the pressure sensor 2 with the pressure maintaining plate, it is observed whether the value of the pressure sensor 2 corresponds to the value of the pressure sensor 1 or the weight. If they correspond, the pressure maintaining mechanism is accurate. Otherwise, it can be debugged. When the pressure value is adjusted, the weight of the pressure maintaining block and the increase or decrease of the weights are used to feed back to the pressure sensor 2 for calibration to measure 20N, or the compression of the spring is adjusted so that the value displayed by the pressure sensor 1 corresponds to the pressure sensor 1.

[0012] The beneficial effect of the utility model is that since only one set of optical machines is positioned on the fixture carrier, and the press-fitting position of the reflective sheet to be assembled by the optical machine is set horizontally, that is, the structural design realizes the change of installing two lenses in a single station to installing one lens in a single station, thereby eliminating the motor rotation mechanism, thereby improving the stability during press-fitting and increasing the accuracy of press-fitting. At this time, an independent pressure-keeping mechanism can be added to the tooling bottom plate by being arranged on the opposite side of the lens material table, so that after the reflective sheet is placed in the press-fitting position, the reliability of press-fitting can be further ensured by the driving cooperation of the avoidance cylinder and the pressure-keeping cylinder, and the fixed-value pressing cooperation of the pressure-keeping plate.

[0023] Example 1

[0024] like Figure 1-6 As shown, a clamping carrier suitable for assembling a 45° reflective sheet of an optical machine, in this embodiment, includes a tooling base plate 1 and a lens material table 2, a fixture carrier 3 and a pressure-maintaining mechanism 4 arranged in sequence on the tooling base plate 1, a reflective sheet 5 to be assembled is placed on the lens material table 2, the fixture carrier 3 is used to position a group of optical machines 6, and the press-fitting position of the reflective sheet 5 to be assembled on the optical machine 6 is horizontally set. At this time, the robot can clamp the reflective sheet 5 on the lens material table 2 by adsorption and place it horizontally on the press-fitting position of the optical machine 6, which is more convenient to go back and forth, and the pressure-maintaining mechanism 4 includes an avoidance cylinder 41, an avoidance slide 42, a pressure-maintaining cylinder 43, a pressure-maintaining slide 44, a slide rail 45, a pressure-maintaining plate 46 and a pressure-maintaining mold Group 47, the avoidance cylinder 41 is installed on the tooling base plate 1, and a pressure-maintaining cylinder 43 is installed on the avoidance slide 42 at its driving end through a stand 48, and a pressure-maintaining plate 46 is slidably installed on the pressure-maintaining slide 44 at the driving end of the pressure-maintaining cylinder 43 through a group of slide rails 45, and the sliding direction of the slide rails 45 is the same as the driving direction of the pressure-maintaining cylinder 43. The pressure-maintaining plate 46 is used to horizontally approach the optical machine 6 on the fixture carrier 3 under the drive of the avoidance cylinder 41. The pressure-maintaining plate 46 is used to vertically press against the reflective sheet 5 at the press-fitting position under the drive of the pressure-maintaining cylinder 43, and the pressure-maintaining module group 47 is connected to the pressure-maintaining plate 46 to maintain a constant pressure when the pressure-maintaining plate 46 vertically presses against the reflective sheet 5;

[0025] At this point, since only one set of optical machines 6 is positioned on the fixture carrier 3, and the press-fitting position of the optical machine 6 to be assembled with the reflective sheet 5 is set horizontally, that is, this structural design realizes the change of single-station installation of two lenses to single-station installation of one lens, thereby eliminating the motor rotation mechanism, thereby improving the stability during press-fitting and increasing the accuracy of press-fitting. At this time, it is arranged on the opposite side of the lens material table 2, and an independent pressure holding mechanism 4 can be added to the tooling base plate 1, so that after the reflective sheet 5 is placed in the press-fitting position, the reliability of press-fitting can be further ensured by the driving cooperation of the avoidance cylinder 41 and the pressure holding cylinder 43, and the fixed value pressing cooperation of the pressure holding plate 46.

[0026] The pressure-maintaining module 47 includes a bottom block 473, a pressure sensor 474, a connecting block 475, a bolt 476, and a spring 477. The bottom block 473 is fixed on the pressure-maintaining slide 44, on which a pressure sensor 474 is installed. The bottom of the connecting block 475 is installed at the detection end of the pressure sensor 474, and two groups of bolts 476 are also installed thereon. The bolts 476 are guided through the edges of both sides of the pressure-maintaining plate 46, and the springs 477 are sleeved outside the bolts 476, and the springs 477 are pressed between the ends of the bolts 476 and the edges.

[0027] At this point, after the pressure-maintaining plate 46 is displaced to the top of the reflective sheet 5, the pressure-maintaining cylinder 43 drives the pressure-maintaining slide 44 to displace a certain distance, and the buffer compression of the spring 477 can be used to achieve a certain pressure value of the pressure sensor 474. The use of the pressure-maintaining module 47 in this way can solve the problem of the limitation of the force value range, but the pressure-maintaining accuracy value for weak forces will also be slightly poor.

[0028] The fixture carrier 3 includes a gantry carrier 31, a support platform 32, a clamping cylinder 33 and a clamping block 34. The gantry carrier 31 is arranged on both sides of the avoidance cylinder 41, and the support platform 32 is installed at an upper inclination angle of 45°. The clamping cylinder 33 is installed on both sides of the gantry, and a clamping block 34 positioned on the support platform 32 is installed on the driving end thereof. The clamping block 34 cooperates with the support platform 32 to clamp the optical machine 6 placed on the support platform 32.

[0029] The clamping carrier also includes a set of pressure calibration jigs 7, which are used to be loaded on the avoidance slide 42 when calibrating the pressure, and a set of pressure sensors 8 are installed thereon. Therefore, by placing the reflective sheet 5 on the pressure sensor 8, the pressure maintaining plate 46 is crimped against the reflective sheet 5 on the pressure sensor 8, and observing whether the value of the pressure sensor 8 corresponds to the value of the pressure sensor 474 or the weight. If they correspond, the pressure maintaining mechanism 4 is accurate, otherwise, it can be debugged. When the pressure value is adjusted, the weight of the pressure maintaining block and the increase or decrease of the weight are fed back to the pressure sensor 8 for calibration to measure 20N, or by adjusting the compression amount of the spring 477, the value displayed by the pressure sensor 474 corresponds to the pressure sensor 474.

[0030] Example 2

[0031] like Figure 7As shown, a clamping carrier suitable for assembling a 645° reflector 5 of an optical machine. In this embodiment, the difference from Example 1 is that the pressure-maintaining module 47 includes a substrate 471 extending outward from both sides of a pressure-maintaining plate 46 and a weight group 472 positioned on the substrate 471. When adjusting the pressure value of the pressure-maintaining plate, it is only necessary to determine the pressure value based on the dead weight of the pressure-maintaining plate 46 and the weight after the weight is added or reduced. For the pressure-maintaining module 47 using weights, a smaller accuracy error range can be ensured, but the force value range has certain limitations. Therefore, in actual production, it is suitable for situations where the pressure-maintaining value range is smaller.

[0032] The working principle of the utility model is as follows: since only one group of optical machines 6 are positioned on the fixture carrier 3, and the press-fitting position of the optical machine 6 to be assembled with the reflective sheet 5 is set horizontally, that is, the structural design realizes the change of installing two lenses in a single station to installing one lens in a single station, thereby eliminating the motor rotation mechanism, thereby improving the stability during press-fitting and increasing the accuracy of press-fitting. At this time, it is arranged on the opposite side of the lens material table 2, and an independent pressure-keeping mechanism 4 can be added to the tooling base plate 1, so that after the reflective sheet 5 is placed in the press-fitting position, the reliability of press-fitting can be further ensured by the driving cooperation of the avoidance cylinder 41 and the pressure-keeping cylinder 43, and the fixed-value pressing cooperation of the pressure-keeping plate 46.

Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
