Description

Technical Field

[0001] The utility model relates to a pressing device, in particular to a pressure-maintaining assembly mechanism for a laser radar housing. Background Art

[0002] In some production processes, glue is needed to fix two workpieces, and some glues are not instant-drying glues. Generally, it takes about 8 hours to fully solidify in order to achieve a better bonding effect. In order to ensure the bonding efficiency of the glue, relative motion cannot be generated between the two workpieces, so a device for maintaining the pressed state of the workpieces is needed. For example, Chinese patent CN201922374929.1 discloses a pressure-maintaining device, which includes a frame (1), a pressure-maintaining feeding platform (2) and a pressure-maintaining movable plate (3) that reciprocates and covers the pressure-maintaining feeding platform (2), and a buffer mechanism (4) for buffering the instantaneous pressure when the pressure-maintaining movable plate (3) contacts the product near one end of the pressure-maintaining feeding platform (2). The pressure-maintaining feeding platform (2) is provided with a plurality of material platforms for placing products. This device uses a buffer mechanism to reduce the instantaneous pressure exerted by the pressure-maintaining movable plate on the product, effectively solving the problem of product warping caused by excessive instantaneous pressure when the pressure-maintaining plate contacts the product in existing pressure-maintaining devices. However, this device may result in two products not being fully bonded, i.e., an incomplete press fit, which may result in defects. Utility Model Content

[0003] In view of this, the present invention provides a pressure-maintaining assembly mechanism for a laser radar housing to solve the above-mentioned problem.

[0004] A pressure-maintaining assembly mechanism for a laser radar housing comprises a frame, a rotating assembly mounted on the frame, a lifting assembly mounted on one side of the rotating assembly, a first jig mounted on the rotating assembly, and a second jig mounted on the lifting assembly. The lifting assembly comprises at least two guide rails mounted on the frame, a base slidably mounted on the guide rails, at least two tension springs mounted on one side of the base, a base block mounted on the base, and at least two sets of compensation components mounted on the base.

The bottom surface of the chamber is provided with at least four compression springs, one end of each compression spring abutting the base and the other end abutting the base block. At least two ball-end plugs are mounted on each of the four inner sidewalls of the chamber, the ends of each ball-end plug abutting the sidewalls of the base block. The compensation component comprises a guide post fixedly mounted on the base and a guide cylinder fixedly mounted on the base block. The guide post is movably inserted into the guide cylinder and is in an inverted conical shape, with its circumferential diameter gradually decreasing toward the base. The guide cylinder is fixedly inserted into a through hole on the base block, and the diameter of the inner side wall of the guide cylinder is equal to the diameter of the largest outer side wall of the guide post.

[0017] The following is a further detailed description of specific embodiments of the present invention. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the scope of protection of the present invention.

[0018] like Figure 1 , which is a schematic structural diagram of the pressure-maintaining assembly mechanism of the laser radar housing provided by the present invention. The pressure-maintaining assembly mechanism of the laser radar housing includes a frame 10, a rotating assembly 20 disposed on the frame 10, a lifting assembly 30 disposed on one side of the rotating assembly 20, a first fixture 40 disposed on the rotating assembly 20, and a second fixture 50 disposed on the lifting assembly 30. It is conceivable that the pressure-maintaining assembly mechanism of the laser radar housing also includes some other functional modules, such as a power module, a drive module, etc., which are technologies well known to those skilled in the art and will not be described in detail here.

[0019] It should be noted that the pressure-maintaining assembly mechanism of the laser radar housing is used to press two shells coated with glue against each other and maintain this state until the glue solidifies, thereby forming a laser radar housing.

[0020] The frame 10 is used to carry various components so that they can be coordinated with each other, thereby completing the assembly of the laser radar housing.

[0021] See also Figures 2 to 5 The rotating assembly 20 includes a rotating shaft 21 rotatably mounted on the frame 10 , a base plate 22 mounted on the rotating shaft 21 , at least two rotary cylinders 23 mounted on the base plate 22 , a locking cylinder 24 mounted on one side of the rotating shaft 21 , and a rotating block 25 fixedly mounted on an end of the rotating shaft 21 .

[0022] The rotating shaft 21 is connected to the output end of an external driving motor, so that the rotating shaft 21 rotates under the drive of the driving motor. The base plate 22 is fixedly arranged on one side of the rotating shaft 21, thereby driving the base plate 22 to rotate.

[0023] A plurality of positioning holes and positioning pins are provided on a side of the base plate 22 facing away from the rotating shaft 21 , which correspond to and match the first fixture 40 , thereby positioning the first fixture 40 placed on the base plate 22 .

[0024] At least two of the rotary cylinders 23 are arranged opposite to each other, and their output ends are respectively provided with a pressure rod 26. When the first jig 40 loaded with the shell is placed on the substrate 22, the rotary cylinder 23 drives the pressure rod 26 to rotate so that the pressure rod 26 can be above the first jig 40 and the shell to prevent the first jig 40 from falling off from the substrate 22 after the rotating shaft 21 rotates.

[0025] A locking block 27 is provided at the output end of the locking cylinder 24. The rotating block 25 has a groove corresponding to the position of the locking block 27 after rotating 90° with the rotating shaft 21. In this way, the locking cylinder 24 drives the locking block 27 to be inserted into the groove, thereby fixing the rotating shaft to prevent it from rotating.

[0026] The lifting assembly 30 includes at least two guide rails 31 arranged on the frame 10, a base 32 slidably arranged on the guide rails 31, at least two tension springs 33 arranged on one side of the base 32, a base block 34 arranged on the base 32, at least two groups of compensation components 35 arranged on the base 32, and at least two air nozzles 36 arranged on one side of the base block 34.

[0027] The length direction of the guide rail 31 is perpendicular to the length direction of the rotating shaft 21 , and the base 32 is connected to an external driving cylinder, so that the base 32 can reciprocate along the length direction of the guide rail 31 when driven by the driving cylinder.

[0028] The length direction of the tension spring 33 corresponds to the length direction of the guide rail 31. One end of the tension spring 33 is hooked on the frame 10, and the other end is hooked on the base 32. In this way, after the base 32 moves toward the rotating shaft 21 and the assembly operation is completed, the tension spring 33 can be used for reset work.

[0029] The base 32 is provided with a chamber for accommodating the base block 34, and at least four compression springs 37 are provided on the bottom surface of the chamber. One end of the compression spring 37 abuts against the base 32, and the other end abuts against the base block 34. In this way, during assembly operations, the compression spring 37 can provide a certain buffer space for the base block 34.

[0030] At least two ball plugs 38 are respectively provided on the four inner side walls of the chamber of the base 32, and the ends of the ball plugs 38 abut against the side walls of the base block 34. In this way, when the compensation component 35 is compensating, the ball plugs 38 can keep the base block 34 in a stable state at all times, thereby cooperating with the compensation component 35 to more completely press the two shells together.

[0031] The compensation component 35 includes a guide column 351 fixedly disposed on the base 32 and a guide cylinder 352 fixedly disposed on the base block 34 .

[0032] The guide post 351 is movably inserted into the guide cylinder 352. The guide post 351 is designed in an inverted conical shape, with its circumferential diameter gradually decreasing toward the base 32. A stopper 353 is provided at the end of the guide post 351 away from the base 32. The guide cylinder 352 is fixedly inserted into a through-hole in the base block 34, and the diameter of the inner sidewall of the guide cylinder 352 is equal to the diameter of the largest outer sidewall of the guide post 351. Before the pressure-maintaining operation is performed, the stopper 353 abuts the end of the guide cylinder 352, thereby preventing the base block 34 from falling off. During the pressure-maintaining operation, the two shells are pressed against each other. Under the action of the mutual force, the base block 34 moves toward the base 32, the compression spring 37 is compressed, and there is a gap between the outer wall of the guide column 351 and the inner wall of the guide cylinder 352. In this way, when the two shells are not aligned with each other, the gap will cause the base block 34 to be slightly offset to compensate for the error between the two shells, so that the two shells can be pressed together more completely, thereby improving production accuracy and reducing the defective rate.

[0033] A plurality of positioning holes and positioning pins are provided on a side of the base block 34 facing away from the base 32 , which correspond to and match the second fixture 50 , thereby positioning the second fixture 50 placed on the base block 34 .

[0034] One end of the air nozzle 36 is connected to an external air pump module, and the other end protrudes from the surface of the base block 34. The end of the air nozzle 36 protruding from the base block 34 has a flexible tube. The second jig 50 has two through-holes corresponding to the positions of the two air nozzles 36. When the second jig 50 is placed on the base block 34, the air nozzle 36 abuts against the through-holes. In this way, the air pump module firmly adsorbs the housing placed on the second jig 50 to the second jig 50, thereby stabilizing the pressing process of the two housings.

[0035] The first jig 40 is equipped with two pressing rods 41, which are used to press the housing placed on the first jig 40, thereby further securing the housing. The first jig 40 is provided with at least two locking rods 42 on the side facing the second jig 50. Each locking rod 42 has a concave latching portion 43 formed on its circumferential outer wall. The two locking rods 42 cooperate with the second jig 50 to secure the two housings. The specific manner of this cooperation will be described below.

[0036] The second jig 50 is provided with a through-hole 51 at the position corresponding to the two locking rods 42, and a block 52 is provided on one side of the through-hole 51. The middle section of the block 52 is rotatably provided on the second jig 50, and one end of the block 52 corresponds to the through-hole 51, and the other end has a spring 53. Pressing the block 52 in this way causes the spring 53 to be compressed, so that one end of the block 52 is away from the through-hole 51, and the pressing rod 41 on the first jig 40 is passed through the through-hole 51. At this time, the block 52 is released, and under the release of the elastic potential energy of the spring 53, the block 52 is clamped into the buckle portion 43, thus completing the assembly between the two jigs, so that the two shells between the first and second jigs 40 and 50 remain in a pressed state until the glue solidifies, thereby forming a laser radar shell. At this time, the assembly of the first and second fixtures 40 and 50 is removed, which ensures the pressed state of the shell and also enables the pressure-maintaining assembly mechanism of the laser radar housing to return to its initial state and continue with the next pressure-maintaining work.

[0037] Compared to the prior art, the pressure-maintaining assembly mechanism for the lidar housing provided by the present invention rotates the first fixture 40 and a shell to a pressing position via the rotating assembly 20. Under the action of the lifting assembly 30, the first and second fixtures 40 and 50 are assembled, and the pressing operation between the two shells is simultaneously completed. During the pressing operation, if the two shells are not completely aligned, the gap between the outer wall of the guide column 351 and the inner wall of the guide cylinder 352 will cause the base block 34 to slightly offset to compensate for the error between the two shells, thereby allowing the two shells to be pressed together more completely, thereby improving production accuracy and reducing the defect rate.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent replacements or improvements within the spirit of the present invention are included in the scope of the claims of the present invention.
