Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of lamp manufacturing, and particularly relates to a pneumatic flipping mechanism with self-locking ability. Background Art
[0002] In the manufacturing field of the automotive industry, screw assembly parts are one of the most widely used applications. When assembling and producing automotive taillights, screws are required to connect various structures inside the lamp.
[0003] For the existing locking forms of lamp parts, currently, a manipulator is usually adopted to complete the automatic screw-locking process in product assembly. Generally, it is necessary to ensure that the angle of the screw at the locking point is perpendicular to the bottom plane. However, as the types of lamp products are increasing and the structures are becoming more and more complex, there are often multiple screws locked at multiple angles when two parts are fastened. At the same time, considering factors such as the floor area of the production line, production rhythm, and equipment cost during product production, the lamp will be flipped in one process to ensure that screws at different angles can be locked in the same process.
[0004] In the prior art, there are the following several types: 1. Manually lock the screws between lamp parts, but this method cannot ensure whether the parts are missing screws or the quantity is accurate. Also, since the angle of the screw needs to be perpendicular to the bottom plane during screw locking, the production rhythm of the product will be increased. 2. Use a motor flipping structure to achieve the locking of screws at one angle and also need to consider the anti-error of the locking quantity. Not only is the structure complex, but also the space usage is large, the cost is too high, it is prone to failure, and it is difficult to debug. It can only rotate in one direction and gradually does not meet the production requirements. In view of the above problems, a pneumatic flipping mechanism with self-locking ability, which has a simple structure, can be flipped in multiple directions, has anti-error (self-locking) of the locking quantity, and low cost, is very important. Summary of the Utility Model
[0005] In order to solve the technical problems of high cost and slow speed in using a motor to flip parts in the prior art, the present application proposes a pneumatic flipping mechanism with self-locking ability, which solves the above technical problems.
[0006] The technical solution adopted by the utility model to solve its technical problems is:
[0007] The utility model provides a pneumatic flipping mechanism with self-locking ability, comprising: a base, on which two vertical rods are arranged; a stacked flipping upper plate and a flipping lower plate, where the flipping upper plate is used for placing lamp parts, and two opposite sides of the flipping lower plate are rotatably hinged to the corresponding vertical rods simultaneously, and one side of the flipping upper plate is pivotally hinged to one of the vertical rods with this side as the rotation axis; a lower plate cylinder, which is arranged on the base to push the flipping lower plate to drive the flipping upper plate to rotate together; and an upper plate cylinder, which is arranged on the base to separately push the flipping upper plate to flip.
[0008] Further, both the lower plate cylinder and the upper plate cylinder are vertically arranged between the flipping lower plate and the base.
[0009] Further, a hollowed-out part for avoidance is formed on the flipping lower plate, so that the upper plate cylinder can directly push the flipping upper plate without being interfered by the flipping lower plate.
[0010] Further, the cylinder body of the upper plate cylinder is movably arranged on the base, so that the upper plate cylinder can avoid the flipped flipping lower plate and the flipping upper plate, so as to prevent the upper plate cylinder from blocking the rotation path when the flipping lower plate or the flipping upper plate rotates at a large angle.
[0011] Further, the cylinder body of the upper plate cylinder is arranged on a sliding table, and the sliding table is fixed to the piston rod of a horizontally arranged sliding table cylinder.
[0012] Further, a push block is fixed on the piston rods of the lower plate cylinder and the upper plate cylinder, a driven block is hinged to the push block, and the hinge point between the driven block and the push block is offset so that the hinge point is not on the extension line of the piston rod.
[0013] Further, the hinge hole at the hinge point between the driven block and the push block is an oval hole.
[0014] Based on the above technical solutions, the technical effects that the utility model can achieve are:
[0015] The pneumatic flipping mechanism with self-locking ability of the present utility model, the flipping upper plate is used to place and fix the lamp parts to adjust the relative angle between the surface to be locked of the lamp parts and the manipulator of the supporting equipment, and then the locking device of the manipulator locks the lamp parts. The pneumatic flipping mechanism with self-locking ability of the present utility model has mainly three adjustment angles in practical applications. The first is the initial position, that is, when the plate surface of the flipping upper plate is parallel to the base surface and neither the lower plate cylinder nor the upper plate cylinder is actuated, the angle at which the lamp parts are placed on the flipping upper plate. The second is when the piston rod of the lower plate cylinder extends and the flipping upper plate is rotated, the angle of the lamp parts after being rotated with the flipping upper plate. The third is when the lower plate cylinder does not work and the piston rod of the upper plate cylinder extends and the flipping upper plate is flipped, the angle of the lamp parts after being flipped with the flipping upper plate. Since the cylinder action is faster and the cost is lower than the motor rotation speed, and the piston rod can complete self-locking when moving to the extreme position, the technical problem of high cost and slow speed in the prior art when using a motor to flip parts is solved.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0023] like Figures 1-4 As shown, the pneumatic flipping mechanism with self-locking ability of the utility model fixes the lamp parts on the flip upper plate 2. When the screws of the lamp parts have multiple locking angles, one of the locking angles is ensured to be placed vertically with the base 1. The start button of the control system is pressed, and the pneumatic flipping mechanism starts to work. The equipment ventilates each cylinder to ensure that the cylinder is locked and self-locking after ventilation. At this time, the first locking point, that is, the initial placement angle of the lamp parts is perpendicular to the plate surface of the flip upper plate 2. The manipulator of the supporting equipment directly completes the locking action, and the counting function of the manipulator is synchronized with the locking action to confirm the number of screw locks. If the number is inaccurate, the program will feedback to the feeder of the lower plate cylinder 4 or the upper plate cylinder 5 to allow the cylinder to automatically lock and stop the next step of the program; if the number is accurate, the program will feedback to the feeder of the lower plate cylinder 4 or the upper plate cylinder 5.
[0024] The principle of the offset of the hinge point between the moving block and the push block 7 is that the hole on the push plate for assembling the linear bearing 73 must be staggered on the extension line of the cylinder piston rod, and the waist-shaped hole 72 on the driven plate must be on the side of the extension line of the piston rod. If this structural design is not performed, Figure 5 As shown, the opening (dashed line) on the push block 7 is located on the extension line of the piston rod, and the thrust F is vertically upward, but the required direction of the driven force is limited to F' by the waist-shaped hole 72, F⊥F', and a dead point appears. Therefore, the push block 7 cannot drive the driven plate (dead point problem) is solved, so the second angle rotation of the screw of the lamp part is realized to be perpendicular to the base plate, and the robot action and program judgment of the above-mentioned equipment are repeated.
[0025] When there is a third locking for the screw of the lamp part and the number of locking for the first two angular screws is normal, the feeder of the lower plate cylinder 4 receives a signal and returns to the initial placement angle of the lamp. The slide cylinder 6 receives a signal and moves linearly, driving the slide 61. The slide 61 drives the cylinder body of the upper plate cylinder 5 to move below the flipping upper plate 2. The hollow part 31 of the flipping lower plate 3 stops moving. The feeder of the upper plate cylinder 5 receives a signal, the piston rod extends, and the push block 7 moves upward, driving the driven block 71 to lift the flipping upper plate 2. At this time, the manipulator in the supporting equipment repeats the actions of the above locking and judgment procedures to ensure that the locking angle of the third locking point is perpendicular to the base 1. Thus, the locking action is completed.
[0026] Note here: If the third locking angle is a dihedral angle, that is, the locking angle has angles in two directions, the lower plate cylinder 4 does not need to return to the zero position, but returns to be parallel to the first angle of the dihedral angle. The upper plate cylinder 5 pushes the flipping upper plate 2 to ensure it is parallel to the second angle of the dihedral angle. At this time, the locking screw is perpendicular to the bottom plate.
[0027] The pneumatic flipping mechanism with self-locking ability of the present utility model uses pneumatic flipping instead of electric flipping to achieve flipping at two angles, reduce costs, and improve the production beat. The push block 7 of the lower plate cylinder 4 and the upper plate cylinder 5 and the driven block 71 are offset. The offset structure cooperates with the way of converting the linear motion of the pneumatic component into rotational motion, and can be used in a variety of other working conditions and occasions in multiple industries. For different requirements of different lamp parts for angles, only need to make a forced limit at the push block 7 to change the angle, which improves the simplicity of the number of locking screws in the whole process and simplifies the self-locking property of the mechanism after missing locking.
[0028] It should be understood that the specific embodiments described above are only used to explain the present utility model and are not used to limit the present utility model. The obvious changes or variations derived from the spirit of the present utility model are still within the protection scope of the present utility model.
