Abstract
Description
Technical Field
[0001] This utility model relates to the field of machining shaft parts in the automotive industry, and in particular to a non-direct contact sensing device. Background Technology
[0002] With rapid technological innovation and soaring labor costs, automated production has become the most effective means of cost reduction that all industries must prioritize. This is especially true in the highly competitive automotive industry. As a Tier 2 supplier in the automotive industry, labor costs will account for a very large proportion of the total product cost. Therefore, in the next few years, how to effectively reduce labor costs while ensuring quality will be the key to survival for Tier 2 suppliers in the automotive industry.
[0003] Steering rods for automotive steering systems and shock absorber rods for automotive shock absorption systems require bar stock to pass through double-headed lathes, centerless grinders, and other precision machining equipment due to processing requirements. The bar stock needs to move between machine tools and be positioned at each workstation. Currently, during the feeding process, the bar stock directly contacts the sensors, resulting in frequent and prolonged impacts that damage the sensors. Furthermore, frequent sensor replacements increase costs, and the sensors, being directly exposed, are susceptible to various external factors affecting positioning accuracy. Utility Model Content
[0004] The purpose of this invention is to overcome the above-mentioned shortcomings of existing devices and to provide a non-contact sensing device.
[0005] This utility model is achieved through the following technical solution:
[0006] A non-contact sensing device includes a lifting mechanism, a sensor module, a sensing base, a sensing stop, and a conveying mechanism for conveying bar stock. The sensing stop is rotatably connected to the sensing base. The sensor module is connected to the sensing base and is used to detect the rotation of the sensing stop. The lifting mechanism is connected to the sensing base and is used to drive the sensing base to move up and down, so that the sensing base, the sensor module, and the sensing stop are all located on the conveying mechanism, so that the bar stock can contact the sensing stop or move away from the conveying mechanism to convey the bar stock.
[0007] Furthermore, the top of the sensing block is rotatably connected to the top of the sensing base, and a receiving cavity is formed between the sensing base and the sensing block, with the sensor module located within the receiving cavity.
[0008] Furthermore, the non-contact sensing device also includes a fixed bracket, the bottom of which is connected to the conveying mechanism, and the lifting mechanism is mounted on the top of the fixed bracket.
[0009] Furthermore, the bottom of the fixed bracket has a waist-shaped hole that extends along the length of the conveying mechanism and is connected to the conveying mechanism.
[0010] Furthermore, the conveying mechanism includes a conveying bracket and a plurality of conveying rollers, the plurality of conveying rollers being spaced apart along the length direction, and the plurality of conveying rollers being rotatably connected to the conveying bracket.
[0011] Furthermore, the lifting mechanism is a cylinder, which is located above the conveying mechanism, and the bottom movable end of the cylinder is connected to the sensing base.
[0012] The beneficial effects of this utility model are as follows:
[0013] This utility model discloses a non-contact sensing device. A conveying mechanism transports bar stock back and forth between different workstations. A lifting mechanism drives the sensing base to move, positioning the sensor module and sensing stop on the conveying mechanism. The bar stock on the conveying mechanism comes into contact with and exerts force on the sensing stop, causing it to rotate. The sensor module detects this rotation to determine if there is material on the conveying mechanism, effectively preventing direct contact between the bar stock and the sensor module. This protects the sensor module and eliminates false sensing caused by debris falling onto it, reducing downtime, saving maintenance costs, improving processing efficiency, and reducing bar stock manufacturing costs. When release is required, the lifting mechanism drives the sensor module, sensing base, and sensing stop to detach from the conveying mechanism, allowing the conveying mechanism to transport the bar stock.

[0029] 10 bar stock Detailed Implementation
[0030] The following description of the embodiments is with reference to the accompanying drawings, which illustrate specific embodiments in which the present invention can be implemented.
[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, this embodiment discloses a non-contact sensing device with a buffer function, which is applied to the machining of shaft parts in the automotive industry and is used to address positioning and sensing issues during the conveying of bar stock 10. The non-contact sensing device includes a sensor module 1, a sensing base 2, a sensing stop 3, a lifting mechanism 4, and a conveying mechanism 5 for conveying the bar stock 10. The sensing stop 3 is rotatably connected to the sensing base 2. The sensor module 1 is connected to the sensing base 2 and is used to detect the rotation of the sensing stop 3. The lifting mechanism 4 is connected to the sensing base 2 and is used to drive the sensing base 2 to move up and down, so that the sensing base 2, sensor module 1, and sensing stop 3 are all located on the conveying mechanism 5, allowing the bar stock 10 to contact the sensing stop 3 or detach from the conveying mechanism 5 to achieve the conveying of the bar stock 10.
[0032] The lifting mechanism 4 drives the sensing base 2 to move up and down. Driven by the up-and-down movement of the sensing base 2, the sensor module 1 and the sensing stop 3 also move up and down. The conveying mechanism 5 transports the bar stock 10 back and forth between different workstations. The lifting mechanism 4 drives the sensing base 2 to move, causing the sensor module 1 and the sensing stop 3 to be positioned on the conveying mechanism 5. The bar stock 10 on the conveying mechanism 5 will contact and exert force on the sensing stop 3, causing the sensing stop 3 to rotate. The sensor module 1 detects the rotation of the sensing stop 3 to determine whether there is material on the conveying mechanism 5, thus effectively preventing direct contact between the bar stock 10 and the sensor module 1, protecting the sensor module 1, and solving the problem of false sensing caused by debris falling onto the sensor module 1. This reduces downtime, saves maintenance costs, improves processing efficiency, and saves on the manufacturing cost of the bar stock 10. When release is required, the lifting mechanism 4 drives the sensor module 1, sensing base 2, and sensing stop 3 to move and detach from the conveying mechanism 5, thus enabling the conveying mechanism 5 to transport the bar stock 10.
[0033] In this embodiment, the lifting mechanism 4 is a cylinder, located above the conveying mechanism 5, with its bottom movable end connected to the sensing base 2. This arrangement ensures that the lifting mechanism 4, sensor module 1, sensing base 2, and sensing stop 3 are all positioned above the conveying mechanism 5. The lifting mechanism 4 drives the sensor module 1, sensing base 2, and sensing stop 3 downwards, positioning the sensing stop 3 on the conveying mechanism 5 for conveying the bar stock 10. The conveying mechanism 5 delivers the bar stock 10, which impacts the sensing stop 3, causing it to rotate. The sensor module 1 detects this rotation, thus detecting that the conveying mechanism 5 is conveying the bar stock 10, effectively preventing direct contact between the bar stock 10 and the sensor module 1. When release is required, the lifting mechanism 4 drives the sensor module 1, sensing base 2, and sensing stop 3 upwards, ensuring that these components do not obstruct the conveying of the bar stock 10.
[0034] The conveying mechanism 5 includes a conveying bracket 51 and multiple conveying rollers 52. The multiple conveying rollers 52 are spaced apart along the length direction, and each of the multiple conveying rollers 52 is rotatably connected to the conveying bracket 51. The multiple conveying rollers 52 are mounted on the conveying bracket 51. During conveying, the conveying mechanism 5 uses the rotation of the multiple conveying rollers 52 to forward convey the bar stock 10 to different workstations. The multiple conveying rollers 52 can rotate clockwise and counterclockwise, allowing the conveying mechanism 5 to convey the bar stock 10 back and forth.
[0035] The non-contact sensing device also includes a fixed bracket 6, the bottom of which is connected to the conveying mechanism 5, and the lifting mechanism 4, which is mounted on the top of the fixed bracket 6. The lifting mechanism 4 is mounted on the conveying bracket 51 of the conveying mechanism 5 via the fixed bracket 6, which is convenient to install and connect, and provides high connection stability.
[0036] The fixed bracket 6 has a waist-shaped hole 61 at its bottom, which extends along the length of the conveying mechanism 5 and is connected to the conveying mechanism 5. The fixed bracket 6 is installed on the conveying bracket 51 through the waist-shaped hole 61. The installation position of the fixed bracket 6 can be adjusted through the waist-shaped hole 61, thereby adjusting the position of the sensor module 1, the sensor base 2, the sensor stop 3, and the lifting mechanism 4. This ensures that the sensor module 1 is positioned between the two conveying rollers 52 during lifting and moving without interfering with the conveying rollers 52, resulting in high safety and stability.
[0037] The top of the sensing block 3 is rotatably connected to the top of the sensing base 2, and a receiving cavity is formed between the sensing base 2 and the sensing block 3, with the sensor module 1 located inside the receiving cavity. The bottom of the sensing block 3 can swing. When the sensing block 3 descends to its lowest point, and the conveying roller 52 delivers the bar stock 10, impacting the sensing block 3, the sensing block 3 retracts. The sensor module 1, fixed to the sensing base 2, can then sense the presence of material, thus preventing direct contact between the bar stock 10 and the sensor module 1. This indicates that there is bar stock 10 on the conveying roller 52. When release is required, the lifting mechanism 4 needs to lift the sensor module 1, the sensing base 2, and the sensing block 3. By placing the sensor module 1 inside the sensing base 2 and the sensing block 3, and providing protection for the sensor module 1, the problem of false sensing caused by debris falling onto the sensor module 1 is effectively solved. This reduces downtime, saves maintenance costs, improves processing efficiency, and reduces the manufacturing cost of the bar stock 10.
[0038] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
