Description

TECHNICAL FIELD

[0001] The utility model relates to a cargo fork field, more specifically, a mechanical collision type fork tip structure. BACKGROUND

[0002] With the development of industrial technology, AGV is widely used in 3C electronics, automobile and automobile parts intelligent factory, medicine, food, semiconductor, lithium battery, photovoltaic and nuclear power industries. The traditional manufacturing industry should try to protect its own production mode in the new market environment, which is flexible and efficient, so that the needs of consumers can be met and more profits can be obtained in the market. Under this background, the AGV with intelligentization as the main part can meet the industry demand.

[0003] When the forklift intelligent AGV is carrying goods, the forklift is usually fixed, and then the fork tip is moved forward. During the process of the fork tip stretching forward, if it is taken blindly, it is easy to collide with the goods. At this time, the fork tip is adjusted in the direction of the gear by installing the diffuse reflection photoelectricity. Since the scanning range of the diffuse reflection photoelectricity is a straight line, only the front of the fork tip can be ensured to be obstacle-free. When the forklift intelligent AGV performs work with a certain height, due to the installation position of the photoelectricity, it is difficult to explore the goods on the upper side of the fork tip and the blind area of the photoelectricity, and the safety is not high. Moreover, the existing fork tip collision sensing device usually has a complex structure, more electrical components, high cost, and problems of difficult actual production installation and daily debugging.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0020] like Figs. 1-3 As shown, the present invention provides a mechanical collision type fork tip structure, including a fork tip mounting seat 1 and a fork tip contact plate 2 movably connected to the fork tip mounting seat 1. The fork tip mounting seat 1 is mounted on the fork by bolts. The fork tip structure is located at the front end of the fork. Obstacle avoidance function is realized through the components installed on the fork tip contact plate 2. When the fork tip contact plate 2 touches the goods, the fork tip contact plate 2 can rotate at a certain angle relative to the fork tip mounting seat 1.

[0021] The fork tip contact plate 2 is provided with a detection photoelectric sensor 3 and a micro switch 4. The fork tip mounting base 1 is provided with a contact element corresponding to the micro switch 4. One side of the fork tip contact plate 2 is rotatably connected to the fork tip mounting base 1, and the other side is limited by a limiting element to restrict the rotation angle of the fork tip mounting base 1. Furthermore, an elastic reset element for resetting the fork tip contact plate 2 after rotation is provided between the fork tip mounting base 1 and the fork tip contact plate 2.

[0022] The detection photoelectric sensor 3 is located at the bottom of the fork tip contact plate 2. A barrier is provided on the bottom side of the fork tip contact plate 2 to effectively protect the detection photoelectric sensor 3. A detection notch is provided at the front end to prevent obstruction of the detection photoelectric sensor 3. The detection photoelectric sensor 3 is a diffuse reflection photoelectric sensor. During the movement of the AGV, the detection photoelectric sensor 3 can detect obstacles in front of the fork tip that are within the light strip's detection range, preventing the fork tip from colliding with obstacles and causing damage.

[0023] Outside the detection range of the photoelectric sensor 3, detection is achieved through the cooperation of the fork tip contact plate 2, micro switch 4, contact element, and elastic reset element. When an obstacle comes into contact with the fork tip contact plate 2, one side of the fork tip contact plate 2 rotates at its rotatable connection with the fork tip mounting base 1. At this time, the micro switch 4 contacts the contact element, generating an electrical signal that is sent to the controller, thereby controlling the AGV's movement direction to avoid the obstacle. The rotation angle of the fork tip contact plate 2 is limited by a limiter to prevent the micro switch 4 from colliding with the contact element due to excessive rotation angle, which could damage the micro switch 4. Simultaneously with the rotation of the fork tip contact plate 2, the elastic reset element is compressed. After avoiding the obstacle, the elastic reset element resets, causing the fork tip contact plate 2 to automatically reset. The micro switch 4 no longer contacts the contact element, and the AGV moves in the specified direction.

[0024] A mounting notch 13 is provided on the fork tip contact plate 2 on the side opposite to the fork tip mounting seat 1, and the micro switch 4 is disposed at the mounting notch 13. The micro switch 4 is disposed at the mounting notch 13, which provides a certain degree of protection for the micro switch 4, preventing obstacles from damaging the micro switch 4, and making the fork tip structure compact.

[0025] The contact element described in this solution includes a contact block 5 fixed to the fork tip mounting seat 1. In this embodiment, the contact block 5 is made of external hexagonal bolts, which can fix the fork tip mounting seat 1 to the fork structure on the one hand, and cooperate with the micro switch 4 on the other hand, so that the micro switch can complete the contact smoothly.

[0026] One side of the fork tip contact plate 2 is connected to the fork tip mounting base 1 via a pin 6, and the other side of the fork tip contact plate 2 is provided with a waist hole 7, into which the limiting member extends. The limiting member includes a limiting rod 8 disposed on the fork tip mounting base 1. The limiting rod 8 is located in the waist hole 7, and the waist hole is slightly larger to provide an effective range of motion, ensuring that the fork tip contact plate 2 can rotate effectively.

[0027] After avoiding the obstacle, the fork tip contact plate 2 is reset by the elastic reset component, and the micro switch 4 is no longer in contact with the contact block 5. The elastic reset component includes a reset spring 9. The fork tip mounting base 1 and the fork tip contact plate 2 are respectively provided with a limiting hole 10 and a limiting hole 11. The two ends of the reset spring 9 are located in the limiting hole 10 and the limiting hole 11, respectively, and the reset spring 9 is in a compressed state. After the fork tip contact plate 2 contacts the obstacle, it rotates. At this time, the reset spring 9 is further compressed. After avoiding the obstacle, the reset spring 9 rebounds, causing the contact plate to reset.

[0028] A screw 12 for adjusting the compression of the return spring 9 is provided in the second limiting hole 11. The screw 12 is threadedly connected to the second limiting hole 11 and faces the return spring 9. By rotating the screw 12, the return spring 9 can be compressed or released, thereby adjusting the degree of compression of the return spring 9.

[0029] This solution sets up a fork tip contact plate 2, with one side of the fork tip contact plate 2 rotatably connected to the fork tip mounting base 1 and the other side limited by a limiting component. In conjunction with a detection photoelectric sensor 3, a micro switch, a contact block 5, a return spring 9, and other structures, it achieves all-round and effective protection for the fork tip. The structure is compact, simple, and reasonably laid out, achieving the anti-collision function under complex conditions without a large number of electrical components.

All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model.
