Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0030] In the prior art, the tray conveying workpiece mode is widely used in the field of automobile manufacturing. When conveying a whole vehicle or a large workpiece, the workpiece area often exceeds the tray size, and a stopper needs to be set to prevent collision. The current mainstream anti-collision device relies on cylinder or electric cylinder drive, and these devices need to be equipped with power source and complex control system, resulting in high production cost, complex operation and maintenance, and affecting economic benefit.

[0031] In order to solve the above problems, the researchers observed that the power-dependent device has inherent defects, and turned to explore a pure mechanical solution. Research shows that the tray has inherent kinetic energy during the conveying line travel, which can be triggered by its own motion. Through the analysis of lever principle and gravity balance mechanism, a device is designed to trigger state conversion by using the gravity of the tray itself, without external energy input to realize the anti-collision function.

[0032] Therefore, please refer to Figures 1 to 3 The application provides an anti-collision rod 100 applied to a tray conveying line, which comprises a rod body 1 extending in the conveying direction, an anti-collision part 2 arranged at one end of the rod body 1, and a trigger part 3 arranged at the other end of the rod body 1, and the two are arranged in the conveying direction. The bottom end of the rod body 1 is provided with a hinged support seat 4, and the support seat 4 is arranged close to the anti-collision part 2, so that the anti-collision part 2 remains in the initial position under the action of gravity. When the tray contacts the trigger part 3, the rod body 1 rotates around the support seat 4, driving the anti-collision part 2 to switch to the blocking position.

[0033] The conveying direction is Figure 1The left and right directions shown in the figure. The rod body 1 refers to the main structure of the anti-collision function, which can be realized by a steel square tube, and its extension direction is parallel to the running axis of the conveying line, forming a rigid support foundation. The anti-collision part 2 refers to the physical structure that blocks the movement of the tray, which can be designed as a metal block with an inclined surface 221, and the inclination angle is controlled within the range of 30° to 60°, which is convenient for the tray to smoothly slide in. The trigger part 3 refers to the contact mechanism for sensing the position of the tray, which is preferably a roller 32 structure, such as a freely rotating nylon roller 32, which reduces friction loss. The support seat 4 refers to the hinged device that realizes rotary motion, which can be realized by a cast steel base with a shaft hole matched with a stainless steel shaft 312, and the hinge point is set near the trigger part 3, forming a lever effect.

[0034] Specifically, the first position is Figure 1 The position of the anti-collision part 2 in the figure. The second position is Figure 2 The position of the anti-collision part 2 in the figure, when the anti-collision part 2 is in the first position, its height is lower than the tray running path, allowing the tray to pass freely. When the tray contacts the roller 32 of the trigger part 3, the downward pressure makes the rod body 1 rotate around the axis of the support seat 4, and the anti-collision part 2 is lifted upward to form a physical barrier. During this process, the hinge position of the support seat 4 is designed to make the displacement of the trigger part 3 amplified by the lever, and the position switching of the anti-collision part 2 is quickly completed. When the tray stops pressing, the anti-collision part 2 automatically resets to the first position under the action of gravity, realizing the cycle use.

[0035] Compared with the prior art, the traditional cylinder type anti-collision device needs to be configured with a gas pump, an electromagnetic valve and a control circuit, and the present scheme completely eliminates the need for a power system. The electric cylinder type anti-collision device relies on a servo motor and a position sensor, and the present scheme realizes state switching through mechanical linkage, and the structural complexity is reduced by more than 60%. In the prior art, the response time of the anti-collision device is affected by the delay of the gas circuit or the circuit, and the present scheme uses direct mechanical contact, and the action response speed is high.

[0036] Through the above technical scheme, the present application successfully eliminates the need for power devices and electrical control systems, reduces the number of anti-collision mechanism parts to 5 core components, and reduces the manufacturing cost. The device uses the principle of gravity self-resetting, and can complete the cycle action without manual intervention, and the mechanical linkage structure has improved reliability.

[0037] The present application further proposes that the anti-collision part 2 includes a stop end 21 and a connecting end 22 arranged opposite to each other, the connecting end 22 is connected above the rod body 1, and the top of the connecting end 22 forms an inclined surface 221, which is inclined downward away from the stop end 21.

[0038] The stop end 21 refers to a structure component at the end of the anti-collision part 2 that forms a block when in contact with the tray, and can be formed by stamping or casting, for example, with a thickness of 3-5 mm, to physically limit the tray in the second position. The connecting end 22 refers to the transition structure connecting the anti-collision part 2 to the rod body 1, which can be achieved by welding or bolt fixation, for example, with a length of 1.2-1.5 times the diameter of the rod body 1, to establish a stable connection between the anti-collision part 2 and the rod body 1. The inclined surface 221 refers to a continuous inclined surface structure formed at the top of the connecting end 22, which can be designed with an inclination angle of 30-45 degrees, and a polyurethane wear-resistant coating can be provided on the surface to guide the tray to slide in the inclined direction above the rod body 1.

[0039] Specifically, when the tray contacts the anti-collision part 2 in the conveying direction, the downward structure of the inclined surface 221 allows the tray bottom to form sliding contact with the connecting end 22, allowing the tray to pass smoothly. After the tray completely crosses the anti-collision part 2, the rod body 1 is reset under the action of gravity, and the stop end 21 remains vertical to allow the tray to pass. When there is a tray on the trigger part 3, the rod body 1 rotates counterclockwise around the support seat 4, and the stop end 21 is lifted upward to mechanically interfere with the tray edge when stopping the subsequent tray.

[0040] Compared with the prior art, the traditional cylinder flip stopper needs to rely on a pneumatic system to maintain the working state, and there is a risk of misoperation caused by pressure fluctuations. The present scheme, through the cooperation of the inclined surface 221 and the stop end 21, can automatically switch between the two working states only by relying on mechanical structure. The existing electric cylinder type anti-collision device needs to be configured with a position sensor and a control system, which has the defect that electrical components are easily disturbed by the environment. The present scheme completely avoids such problems through pure mechanical cooperation.

[0041] Through the above technical scheme, the present application realizes bidirectional function switching under the condition of no power, the inclined surface 221 ensures low resistance sliding of the tray during travel, the stop end 21 provides a reliable vertical blocking surface, and the structure design of the connecting end 22 effectively prevents the phenomenon of jamming caused by deformation of the components during movement, and the overall structure does not need to maintain lubricating components, significantly improving the reliability of the equipment operation.

[0042] The present application further proposes that the stop end 21 forms a protrusion in the direction away from the connecting end 22 to form a protrusion 211, and the connection between the protrusion 211 and the connecting end 22 forms a stop step 222.

[0043] The convex block 211 refers to an entity structure extending outward from the end of the anti-collision part 2, which can be implemented in the form of a cuboid or trapezoidal block structure, and is fixed to the connecting end 22 by welding or casting. The convex block 211 increases the longitudinal size of the contact surface to form a double blocking mechanism for the stop end 21. The stop step 222 refers to a vertical transition surface formed between the root of the convex block 211 and the connecting end 22, which can be implemented in the form of a right-angle bending or a machined right-angle edge, and forms mechanical limiting by the right-angle connection of the rigid material. The stop step 222 uses the transverse blocking characteristics of the vertical surface to limit the displacement freedom of the tray.

[0044] Specifically, when the tray contacts the anti-collision part 2, the front end surface of the convex block 211 first bears the impact load, and the pressure is dispersed through the compression strength of the thickness direction of the convex block 211. As the tray continues to move, the right-angle structure formed by the side surface of the convex block 211 and the stop step 222 produces a transverse constraint on the tray, preventing it from slipping along the axis direction of the anti-collision rod 100. At this time, the gravity of the anti-collision part 2 causes the convex block 211 to always be in vertical contact with the tray, and the right-angle structure of the step surface forms a rigid block in three-dimensional space, maintaining the positional stability of the anti-collision part 2 under the combined action of longitudinal impact force and transverse shear force.

[0045] Compared with the prior art, the conventional anti-collision rod 100 only uses a plane or inclined surface structure for blocking, which is easy to slip out of position under the inertial impact of the tray. The convex block 211 structure of the present application forms multi-point support by increasing the contact area, and the stop step 222 forms mechanical locking through geometric limiting, which can achieve bidirectional stopping without relying on frictional resistance. This non-powered mechanical limiting method eliminates the risk of control system failure compared with the prior art driven by air cylinders or electric cylinders.

[0046] Through the above technical solutions, the present application effectively solves the problem of transverse displacement of the tray when it impacts the anti-collision rod 100, and the anti-collision part 2 can withstand longitudinal impact force while suppressing transverse slip. The cooperative action of the convex block 211 and the stop step 222 achieves three-dimensional constraint on the moving direction of the tray, ensuring the stability of the stop position under multiple impacts, and avoiding the anti-collision failure caused by slip.

[0047] The present application further proposes that the trigger part 3 comprises a connecting arm 31 and a roller 32, the roller 32 is rotatably installed on the connecting arm 31, and the outer edge of the roller 32 is exposed outside the connecting arm 31.

[0048] The connecting arm 31 refers to a rigid support structure for connecting the rod body 1 and the roller 32, which can be formed by bending or welding a metal plate, and has sufficient strength to transmit the force of the tray. The roller 32 refers to a cylindrical component that can rotate around a fixed axis, which can be implemented by a mechanism in which a bearing cooperates with a rotating shaft 312, and when the outer surface of the roller 32 contacts the tray, it can produce rolling friction.

[0049] Specifically, one end of the connecting arm 31 is fixedly connected with the rod body 1, and the other end is provided with the roller 32 through the rotating shaft 312. When the tray moves to the trigger part 3 in the conveying direction, the bottom surface of the tray is in contact with the outer edge of the roller 32, and the roller 32 rotates around the rotating shaft 312 under the pushing of the tray. At this time, the rotary motion of the roller 32 converts the linear pushing force of the tray into the torque of the connecting arm 31, and drives the rod body 1 to rotate around the hinge point of the support base 4. The rotation of the rod body 1 makes the anti-collision part 2 lift from the first position to the second position, thereby forming a stop action on the subsequent tray. The whole process does not need external power input, and only relies on the linkage of the mechanical structure to complete the triggering action.

[0050] Compared with the prior art, the traditional cylinder overturning stopper relies on a pneumatic system to provide driving force, and the electric cylinder action type anti-collision device needs a motor and a control circuit to realize position adjustment. The scheme uses the mechanical cooperation of the connecting arm 31 and the roller 32 to drive the trigger mechanism by using the motion energy of the tray itself, without the need for additional power devices and electric control units, and reduces the complex components such as air path, circuit and sensor in the structure.

[0051] Through the above technical scheme, the application effectively solves the problems of system complexity and high cost caused by the dependence of power devices. The rolling friction design of the roller 32 reduces the triggering resistance and avoids misoperation caused by jamming; the pure mechanical structure does not need to regularly maintain power elements, thereby reducing the equipment operation and maintenance cost; the triggering action is directly related to the tray motion, thereby improving the real-time performance and reliability of the anti-collision response.

[0052] The application further provides that the connecting arm 31 comprises an arm body 311, a rotating shaft 312 and two mounting plates 313, the two mounting plates 313 are separately arranged on the two sides of the arm body 311, the arm body 311 is connected with the rod body 1, the roller 32 is arranged between the two mounting plates 313, the rotating shaft 312 penetrates the mounting plate 313 and the roller 32 in sequence, and the outer edge of the roller 32 is exposed outside the mounting plate.

[0053] The arm body 311 is a main support structure of the rod body 1, which can be formed by punching or casting, and is used for transmitting the pushing force applied by the tray and bearing the mounting plate 313. The rotating shaft 312 is a rotating shaft 312 penetrating the mounting plate 313 and the roller 32, which can be realized by using a stainless steel cylinder combined with a bearing or a shaft sleeve structure to ensure the free rotation of the roller 32 around the axis. The mounting plate 313 is a support member symmetrically distributed on the two sides of the arm body 311, which can be fixed with the arm body 311 by welding or bolt connection to form a rigid frame clamping the roller 32. The outer edge of the roller 32 is exposed, which means that the contact surface of the roller 32 exceeds the edge of the mounting plate 313, which can be realized by adjusting the distance between the mounting plates 313 or the diameter size of the roller 32 to ensure the triggering action when in contact with the tray.

[0054] Specifically, the tray contacts the outer edge of the exposed roller 32 when moving in the conveying direction, pushing the roller 32 to rotate around the rotating shaft 312. The mounting plates 313 on both sides of the roller 32 are symmetrically distributed, limiting the axial deviation of the roller 32 during rotation, avoiding the sticking of the rotating shaft 312 or the falling of the roller 32 due to unilateral stress. The rotating shaft 312 penetrates the mounting plate 313 and the center hole of the roller 32, forming a three-point support structure to disperse the impact load applied by the tray. The mounting plate 313 is rigidly connected with the arm body 311, transmitting the force borne by the roller 32 to the rod body 1 to drive the anti-collision rod 100 to rotate around the support seat 4.

[0055] Compared with the prior art, the conventional trigger part 3 usually adopts a single mounting plate 313 or a cantilever structure, and the roller 32 is prone to axial deviation after long-term stress, resulting in trigger failure or frequent maintenance. The layout of the double mounting plates 313 symmetrically supporting can eliminate unilateral stress concentration and avoid the bending of the rotating shaft 312 or the disengagement of the roller 32. At the same time, the design of the exposed roller 32 can realize precise triggering without additional guiding components, reducing the structural complexity.

[0056] Through the above technical scheme, the application solves the problems of high maintenance cost and unstable installation of the roller 32 caused by the complex structure of the trigger part 3. The symmetric arrangement of the mounting plate 313 enhances the deformation resistance of the connecting arm 31, and the cooperation of the rotating shaft 312 and the mounting plate 313 restricts the axial freedom of the roller 32. The exposed roller 32 directly contacts the tray, reducing friction loss. The scheme realizes stable triggering function through mechanical structure optimization without external power or complex control device.

[0057] The application further proposes that the anti-collision rod 100 further comprises two connecting plates 5, which are respectively arranged on both sides of the arm body 311. One end of the connecting plate 5 is fixed with the rod body 1, and the other end of the connecting plate 5 is fixed with the arm body 311.

[0058] Among them, the connecting plate 5 refers to a plate-shaped connecting structure symmetrically distributed on both sides of the arm body 311, which can be rigidly fixed with the rod body 1 and the arm body 311 by welding or bolt connection of metal plate, and the force transmission path is formed by bilateral fixation to disperse the horizontal load. Among them, the two connecting plates 5 are arranged in a mirror-symmetric manner on the left and right sides of the arm body 311, which can be installed in an equal-interval positioning manner, and the symmetric layout realizes force balance to avoid deflection.

[0059] Specifically, when the tray hits the roller 32, the impact force is transmitted to the arm body 311 through the roller 32, and the two side connecting plates 5 disperse and conduct part of the impact force to the rod body 1. Since the connecting plate 5 is rigidly fixed with the rod body 1 and the arm body 311, the transverse bending stress generated by the impact is decomposed by the double-sided support structure, avoiding the fracture or deformation of the single-sided connecting point due to stress concentration. At the same time, the double transmission path formed by the connecting plate 5 improves the connection stiffness of the trigger part 3 and the rod body 1, maintaining the relative position accuracy of the two in the repeated impact process, preventing the anti-collision part 2 from being unable to reset to the first position due to loose connection point.

[0060] Compared with the prior art, the traditional pneumatic cylinder or electric cylinder type anti-collision device relies on a power device to maintain structural stability, while the present scheme realizes the anti-impact performance through the mechanical rigid connection of the double-sided connecting plate 5 without the need for additional power. The single-sided installation structure in the prior art is prone to jamming due to unbalanced load, while the double-sided symmetrical layout evenly distributes the load and eliminates the risk of deflection of the trigger part 3.

[0061] Through the above technical scheme, the present application effectively enhances the connection stability of the trigger part 3 and the rod body 1, avoiding deformation or failure of the connection part during high-speed impact of the tray, and ensuring that the anti-collision part 2 can accurately switch to the second position to realize the stopping function. The double-sided support structure formed by the connecting plate 5 can resist multi-directional impact load, realizing the self-resetting ability of the anti-collision rod 100 without complex control system, reducing maintenance cost.

[0062] The present application further proposes that the support seat 4 is provided with a mounting groove 41, and the bottom end of the rod body 1 is formed with a protruding part 11, which extends into the mounting groove 41 and is hinged with the support seat 4.

[0063] Among them, the mounting groove 41 refers to the recess structure in the support seat 4 for accommodating the protruding part 11, which can specifically form a concave cavity by machining or casting process, and the displacement range of the protruding part 11 is limited by the geometric shape of the groove, realizing the positioning function of the hinge point. Among them, the protruding part 11 refers to the protruding structure formed by the outward extension of the bottom end of the rod body 1, which can be connected with the rod body 1 by welding or integral molding, and the rotation pair is formed by the cooperation of the protruding part 11 and the mounting groove 41, so that the rod body 1 can rotate freely around the hinge point.

[0064] Specifically, the protrusion 11 at the bottom end of the rod body 1 is embedded in the mounting groove 41 of the support seat 4 to form a hinged connection. When the tray contacts the trigger portion 3, the rod body 1 rotates around the hinge point to drive the anti-collision portion 2 to move to the second position. When the tray is separated from the trigger portion 3, the rod body 1 reversely rotates around the hinge point under the gravity of the anti-collision portion 2, so that the anti-collision portion 2 is automatically reset to the first position. The cooperation of the mounting groove 41 and the protrusion 11 not only limits the position of the rotation axis, but also ensures the stability of the rotation process through the geometric constraint of the contact surface, avoiding the deviation or shaking of the rod body 1 during movement.

[0065] Compared with the prior art, the traditional anti-collision device drives the rod body to move through a pneumatic cylinder or an electric cylinder, which requires additional power devices and control systems, resulting in a complex structure and high maintenance cost. The present scheme realizes the rotation and reset of the rod body 1 through a mechanical hinged structure, without the need for an external power source, simplifying the overall structure and reducing the manufacturing cost.

[0066] Through the above technical scheme, the present application solves the problem of complex structure caused by the dependence of the existing anti-collision rod 100 on power devices. The self-resetting function of the rod body 1 is realized by using a hinged structure, reducing the number of parts, and improving the stability of the hinge point through the cooperation of the mounting groove 41 and the protrusion 11, avoiding the loosening of the connection due to long-term use.

[0067] The present application further proposes a flexible gasket 6, which is arranged at the bottom end of the rod body 1. The flexible gasket 6 is used to abut against the tray conveying line.

[0068] The flexible gasket 6 is a buffer component made of elastic material, which can be realized by using rubber or polyurethane material. It absorbs the contact impact between the rod body 1 and the conveying line through elastic deformation. The bottom end of the rod body 1 refers to the terminal region of the anti-collision rod 100 contacting the tray conveying line. After the flexible gasket 6 is fixed in this region, it forms continuous contact with the surface of the conveying line when the rod body 1 rotates around the support seat 4.

[0069] Specifically, when the rod body 1 rotates around the support seat 4, relative movement occurs between the bottom end of the rod body 1 and the tray conveying line. At this time, the flexible gasket 6 replaces the original rigid contact with elastic contact, absorbing the impact force generated during rotation through the compression deformation of the material itself. The elastic deformation of the flexible gasket 6 not only reduces the friction coefficient between the contact surfaces, but also disperses the local stress concentration, thereby reducing the direct collision between metal components. This structure does not rely on external power or complex control, but only relies on the material properties to achieve vibration and noise reduction, which is compatible with the passive working mode of the anti-collision rod 100 relying on gravity triggering.

[0070] Compared with the prior art, the traditional anti-collision rod 100 is in rigid contact with the conveying line, and is prone to surface wear or noise due to friction after long-term operation. The present application converts the rigid contact into elastic contact by adding a flexible gasket 6, which not only avoids direct friction between metals, but also buffers stress through material deformation, without the need for additional power devices or control systems to prolong the service life of the components.

[0071] Through the above technical solutions, the present application effectively reduces the wear rate of the contact area between the anti-collision rod 100 and the conveying line, reduces the noise generated by collision during equipment operation, simplifies the maintenance requirements, and improves the overall durability of the anti-collision rod 100.

[0072] The present application further proposes a technical solution in which the trigger part 3 is integrally formed with the rod body 1.

[0073] The trigger part 3 refers to a mechanism provided at the end of the rod body 1 for contacting the tray, which can be implemented by a combination of a roller 32 and a connecting arm 31, and its function is to receive the contact force generated when the tray moves and transmit it to the rod body 1. Integrally formed means that different components are processed into a single continuous body through casting, forging or additive manufacturing process, which can be realized by mold casting molding, and the continuous distribution of materials eliminates the assembly interface required for separate connection.

[0074] Specifically, during the manufacturing process of the rod body 1 and the trigger part 3, the connecting arm 31 and the roller 32 mounting structure are directly formed as an extension of the end of the rod body 1. When the tray contacts the trigger part 3, the external force is directly transmitted to the rod body 1 through the integral structure, avoiding the stress concentration phenomenon of bolt connection or welded joints in the separate structure. This manufacturing method does not require threaded holes or welded positioning structures on the rod body 1, thereby eliminating the possibility of assembly error accumulation. In the long-term use process, the fatigue resistance of the integral structure is improved, and the loosening or falling off of the separate components due to vibration does not occur.

[0075] In some specific embodiments, the rod body 1 and the trigger part 3 can be manufactured synchronously using a metal powder laser melting forming process, so that the thickness of the connecting arm 31 gradually transitions with the main beam of the rod body 1. The roller 32 mounting hole is directly formed during forming, without the need for subsequent drilling process.

[0076] Compared with the prior art, the traditional separate anti-collision rod 100 needs to be machined into rod body 1 and trigger part 3 respectively, and then fastened by bolts, which not only increases the assembly time, but also causes the structure to be less rigid due to the fitting error of the contact surface. The integral structure eliminates the procurement and assembly of connecting parts, and also eliminates the risk of structural deformation caused by connection gaps.

[0077] Through the technical scheme, the production process of the anti-collision rod 100 can be simplified, the cost of inventory management of parts is reduced, the load transmission efficiency between the trigger part 3 and the rod body 1 is enhanced, and the abnormal anti-collision function caused by connection failure is avoided.

[0078] The tray conveying line further applies the anti-collision rod 100, and the specific structure of the anti-collision rod 100 refers to the above-mentioned embodiments. Since all the technical schemes of the above-mentioned embodiments are adopted in the tray conveying line, at least all the beneficial effects brought by the technical schemes of the above-mentioned embodiments are achieved, and thus the detailed description is not repeated here. The above-mentioned is only an exemplary embodiment of the present application, and does not limit the patent range of the present application. Any equivalent structural transformation, direct / indirect application in other related technical fields, or direct / indirect application in other related technical fields within the technical concept of the present application, the contents of the present application and the drawings are included in the patent protection range of the present application.
