Description

Technical Field

[0001] This invention relates to the field of piston head processing robot tracks, specifically to a collision-resistant robot walking track for an automated piston head production line. Background Technology

[0002] In automated piston head production lines, robots often extend their working range via walking tracks to achieve multi-station operations. However, traditional walking tracks lack effective end-collision protection mechanisms, typically relying only on simple mechanical blocks or electronic limit switches for protection. When a robot's slider mechanism malfunctions due to program errors, control system failures, or external interference, causing it to collide with the end of the track, a huge instantaneous impact force is generated, which can easily lead to track deformation, transmission system damage, loss of robot precision, and even damage to the robot's structure. Therefore, we propose a collision-resistant robot walking track for automated piston head production lines. Summary of the Invention

[0003] The purpose of this invention is to provide an anti-collision robot walking track for automated piston head production lines. It solves the technical problem that existing walking tracks lack an effective end-collision protection mechanism. When the robot's slider mechanism loses control and impacts the end of the track due to program errors, control system failures, or external interference, it will generate a huge instantaneous impact force, which can easily cause track deformation, transmission system damage, loss of robot precision, or even damage to the robot's body structure.

[0004] The present invention achieves the above objectives through the following technical solutions: A collision-resistant robot walking track for an automated piston head production line includes a track body, a slider mechanism that moves along the track body inside the track body, an installation mechanism for connecting with a robot on the slider mechanism, and collision-resistant safety protection mechanisms symmetrically provided at both ends of the track body. The anti-collision safety protection mechanism includes a limiting plate located at the end of the track body, a contact block located inside the track body for contacting the slider mechanism, and a damping buffer connecting the contact block and the limiting plate.

[0005] A further improvement is that the slider mechanism includes a slider body, on both sides of the slider body, and a first magnetic plate is embedded on the outer side of the movable plate; The anti-collision safety protection mechanism also includes a mounting base located on the inner wall of the side of the track body and inside the contact block. The mounting base has a second magnetic plate on the side facing the movable plate that repels the magnetic poles of the first magnetic plate. The length of the second magnetic plate is greater than the length of the first magnetic plate.

[0006] A further improvement is that the top of the slider body is symmetrically provided with protrusions, and the two sets of protrusions are respectively connected to two movable plates through the first elastic telescopic member on opposite sides. The movable plates are connected to a pull rope, and the other end of the pull rope is connected to the movable end of the second elastic telescopic member. The second elastic telescopic member is located at the bottom of the slider body, and the movable end of the second elastic telescopic member is provided with a friction block. When the slider body moves to the designated position, the second magnetic plate drives the first magnetic plate to squeeze the first elastic telescopic member to move towards the protrusion, and then the pull rope loosens, causing the second elastic telescopic member to elastically reset and drive the friction block to contact the bottom inner wall of the track body.

[0007] A further improvement is that the mounting mechanism includes a connecting seat that fits against the top of the slider body and is located between two sets of protrusions, a mounting plate fixedly mounted on the connecting seat and used for connecting with the robot, a bidirectional telescopic device is provided inside the connecting seat, both output ends of the bidirectional telescopic device are connected to movable blocks, a locking block is fixedly provided on the opposite side of the two sets of movable blocks, and movable openings for the locking blocks to pass through are provided through the side wall of the connecting seat and the protrusions.

[0008] A further improvement is that a pressure sensor is embedded in the side of the contact block facing the slider mechanism, the pressure sensor is electrically connected to an external controller, and the external controller is connected to an alarm. When the pressure sensor detects that the pressure generated by the slider mechanism reaches a preset threshold, the external controller activates the alarm.

[0009] A further improvement is that a third magnetic plate is symmetrically embedded on both sides of the top of the mounting plate, and an electromagnetic plate is embedded at the end of the top inner wall of the track body. The electromagnetic plate and the bidirectional telescopic device are both electrically connected to an external controller. When the pressure sensor detects that the pressure generated by the slider mechanism reaches a preset threshold, the external controller controls the bidirectional telescopic device to drive the locking block into the connecting seat, and the electromagnetic plate is energized to attract the third magnetic plate.

[0010] A further improvement is that the mounting base is slidably disposed on the inner wall of the side of the track body, and the mounting base is connected to the limiting plate through a telescopic device.

[0011] A further improvement is that the outer wall of the track body is provided with several sets of mounting feet.

[0012] The beneficial effects of this invention are as follows: This invention utilizes a collision avoidance safety protection mechanism composed of a limiting plate, contact block, and damping buffer. When the slider mechanism experiences a runaway impact, the damping buffer efficiently absorbs and dissipates the impact kinetic energy, transforming a rigid collision into a flexible buffer. This significantly reduces the risk of damage to the track body, slider mechanism, and robot from instantaneous impact forces. Furthermore, the repulsive action between the first and second magnetic plates achieves magnetic deceleration in a non-contact state. Simultaneously, this magnetic repulsion drives the friction block to contact the inner wall of the track bottom, effectively reducing the kinetic energy of the slider mechanism before it approaches the track end. This further reduces the risk of damage to the track body, slider mechanism, and robot from instantaneous impact forces, extends the overall service life, and ensures the continuous and stable operation of the piston head automated production line.

Detailed Implementation

[0015] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0016] Example 1

[0017] Please see the appendix Figure 1-4A collision-resistant robot walking track for an automated piston head production line includes a track body 100, a slider mechanism 101 that moves along the track body 100 within the track body 100, and an installation mechanism 102 for connecting to a robot on the slider mechanism 101. Collision-resistant safety protection mechanisms 200 are symmetrically provided at both ends of the track body 100. Of course, the walking track is not limited to the above structures. For example, it also includes a transmission mechanism (including servo motor and reducer, gear and rack, etc.) provided in the track body 100 for driving the slider mechanism 101 to move along the track body 100. These will not be described in detail here. By setting collision-resistant safety protection mechanisms 200 at both ends of the track body 100, this walking track can effectively absorb the accidental impact energy generated by the slider mechanism 101 due to program errors or control system failures, thereby preventing the slider mechanism 101, the installation mechanism 102 and the robot it carries from rigidly colliding in the direction of track movement. This significantly reduces the risk of equipment damage and maintenance costs, while ensuring the continuity of the production line and operational safety. The anti-collision safety protection mechanism 200 includes a limiting plate 201 (the limiting plate 201 is U-shaped and can be detachably connected to the track body 100 using a bolt-type structure) located at the end of the track body 100, a contact block 203 located inside the track body 100 and used to contact the slider mechanism 101, and a damping buffer 202 connecting the contact block 203 and the limiting plate 201. The damping buffer 202 is a conventional device in the art, such as a hydraulic or pneumatic damping buffer 202, which will not be described in detail here. When the slider mechanism 101 accidentally loses control and rushes towards the end of the track, it first comes into contact with the contact block 203, and then transmits the impact force to the damping buffer 202. The damping buffer 202 efficiently converts the impact kinetic energy into heat energy dissipation, thereby absorbing and buffering the collision energy, effectively avoiding damage to the equipment structure caused by rigid collisions, significantly reducing maintenance costs and improving system safety.

[0018] Please see the appendix Figure 1-5 As a preferred embodiment, the slider mechanism 101 includes a slider body 1011, which is specifically connected to the output end of the transmission mechanism provided in the track body 100 so as to be driven by the transmission mechanism to move along the track body 100. Movable plates 1013 are provided on both sides of the slider body 1011, and a first magnetic plate 1014 is embedded on one side of the movable plate 1013. The anti-collision safety protection mechanism 200 also includes a mounting base located on the inner side wall of the track body 100 and inside the contact block 203. The mounting base has a second magnetic plate 206 on the side facing the movable plate 1013, which is repelled by the magnetic poles of the first magnetic plate 1014. The second magnetic plate 206 and the mounting base can be detachably fixed by bolts, so that the operator can decide whether to use the second magnetic plate 206 as needed. The length of the second magnetic plate 206 is greater than the length of the first magnetic plate 1014 to form a magnetic field area. When the slider mechanism 101 approaches the end of the track, the first magnetic plate 1014 first enters the magnetic field range of the second magnetic plate 206. The non-contact buffering effect is generated by the magnetic repulsion of the same poles, which effectively reduces the moving kinetic energy of the slider mechanism 101. Then, the final energy absorption is achieved through the contact block 203 and the damping buffer 202. This method reduces the instantaneous load of the collision impact on the robot and track structure, extends the service life of the equipment, and ensures the continuous and stable operation of the production line.

[0019] Preferably, in this embodiment, the top of the slider body 1011 is symmetrically provided with protrusions (the protrusions are integrated with the slider body 1011). The two sets of protrusions are connected to two movable plates 1013 on opposite sides by a first elastic telescopic member 1012 (such as an elastic telescopic rod). Under the action of the first elastic telescopic member 1012, the movable plate 1013 can move relative to the protrusions on the slider body 1011. The movable plate 1013 is connected to a pull rope 1017. The other end of the pull rope 1017 is connected to the movable end of the second elastic telescopic member 1015 (such as an elastic telescopic rod). Optionally, in this embodiment, a guide wheel structure (including a wheel frame and a guide wheel) can be provided on the slider body 1011 to guide the pull rope 1017. The second elastic telescopic member 1015 is provided at the bottom of the slider body 1011. The movable end of the second elastic telescopic member 1015 is provided with a friction block 1016. Optionally, the friction block 1016 is made of wear-resistant rubber material. In the initial state, when the first magnetic plate 1014 and the second magnetic plate 206 have not entered the corresponding range, the second elastic telescopic member 1015 remains compressed under the combined action of the pull rope 1017 and the first elastic telescopic member 1012, keeping the friction block 1016 in non-contact with the inner wall of the bottom of the track body 100 to avoid unnecessary frictional wear. When the slider body 1011 moves to the designated position, the first magnetic plate 1014 and the second magnetic plate 206 generate a magnetic repulsion force of the same pole, and the second magnetic plate 206 drives the first magnetic plate 1014 to squeeze the first elastic telescopic member. 1012 moves toward the protrusion, thereby loosening the rope 1017 and causing the second elastic telescopic member 1015 to elastically reset, driving the friction block 1016 downward to contact the bottom inner wall of the track body 100. In this way, the slider mechanism 101 can be activated in advance when it approaches the end of the track, and the non-contact magnetic force and contact friction can be used to effectively decelerate it, reduce the instantaneous impact force borne by the subsequent contact block 203 and damping buffer 202, improve the reliability and durability of the entire anti-collision safety protection mechanism 200, and at the same time reduce maintenance requirements and extend the service life of key components.

[0020] Preferably, in this embodiment, the mounting base is slidably disposed on the inner side wall of the track body 100, and the mounting base is connected to the limiting plate 201 through a telescopic device 205 (such as an electric telescopic rod). The position of the mounting base can be easily adjusted through the telescopic device 205, so as to flexibly adjust the relative distance between the second magnetic plate 206 and the end of the track. This allows the starting point and intensity of the magnetic buffering effect to be optimized according to actual operating requirements (such as different robot loads and different operating speeds), so as to adapt to various working conditions. It can both start the buffering in advance to ensure safety under high-speed heavy-load conditions and avoid excessive braking under low-speed light-load conditions.

[0021] Preferably, the outer wall of the track body 100 in this embodiment is provided with several sets of mounting feet 300. The mounting feet 300 are fixed to the side wall of the track body 100 using a bolt-like structure, and are also fixed to the ground using a bolt-like structure to ensure the stable use of the track body 100.

[0022] Example 2

[0023] Please see the appendix Figure 1-5Based on Embodiment 1, the mounting mechanism 102 of this embodiment includes a connecting seat 1021 that fits against the top of the slider body 1011 and is located between two sets of protrusions, and a mounting plate that is fixedly mounted on the connecting seat 1021 and used for connecting with the robot. The mounting plate is connected and fixed to the robot (the robot's base) using a bolt-like structure. A bidirectional telescopic device 1022 is provided inside the connecting seat 1021. The bidirectional telescopic device 1022 is a conventional device in the art and will not be described in detail here. Both output ends of the bidirectional telescopic device 1022 are connected to movable blocks 1023. Locking blocks 1024 are fixedly provided on opposite sides of the two sets of movable blocks 1023. The locking blocks 1024 are welded to the movable blocks 1023. Movable openings for the locking blocks 1024 to pass through are provided through the side wall of the connecting seat 1021 and the protrusions. During installation, the connecting seat 1021 is first positioned in the installation area between the two sets of protrusions. Then, the bidirectional telescopic device 1022 is activated to drive the movable blocks 1023 on both sides to move away from each other, thereby driving the locking block 1024 to be precisely inserted into the movable opening of the protrusion to form a rigid mechanical interlock. This achieves a quick and secure connection between the installation mechanism 102 and the slider body 1011. Finally, the robot is fixed by the installation plate.

[0024] Please see the appendix Figure 3-4 Preferably, in this embodiment, a pressure sensor 204 is embedded in the side of the contact block 203 facing the slider mechanism 101. The pressure sensor 204 is a conventional device in the art and will not be described in detail here. The pressure sensor 204 is electrically connected to an external controller, and the external controller is connected to an alarm. When the pressure sensor 204 detects that the pressure generated by the slider mechanism 101 reaches a preset threshold, it causes the external controller to activate the alarm to remind the operator, so that the operator can intervene in time, effectively prevent the collision accident from escalating, and reduce equipment maintenance costs and the risk of production interruption.

[0025] Please see the appendix Figure 3-4 As a preferred embodiment, the top two sides of the mounting plate are symmetrically embedded with third magnetic plates, and the end of the top inner wall of the track body 100 is embedded with an electromagnetic plate 207. The electromagnetic plate 207 and the bidirectional telescopic device 1022 are electrically connected to an external controller. When the pressure sensor 204 detects that the pressure generated by the slider mechanism 101 reaches a preset threshold, the external controller executes a two-level safety response: First, it controls the bidirectional telescopic device 1022 to drive the locking block 1024 into the connecting seat 1021, releasing the mechanical connection between the mounting mechanism 102 and the slider body 1011. At the same time, it sends an energizing signal to the electromagnetic plate 207, causing the electromagnetic plate 207 to attract the third magnetic plate on the mounting plate. This causes the mounting mechanism 102 to separate the robot from the slider mechanism 101 and connect it to the track body 100, maintaining the robot's posture stability while preventing the collision accident from escalating and maximizing the protection of the robot and the precision components of the track from damage.

[0026] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
