Abstract
Description
Technical Field
[0001] This utility model relates to the field of liquid crystal panel transmission equipment technology, and in particular to a novel sensor swing device. Background Technology
[0002] In the manufacturing process of LCD panels, the precise transport of the glass substrate is a crucial step in ensuring product quality. When the LCD panel passes through the transport equipment, the position of the glass substrate needs to be confirmed by an onboard sensor to achieve accurate transport and smooth operation of subsequent processes.
[0003] Currently, the industry commonly uses sensor swing devices to detect the position of glass substrates. Existing sensor swing devices include a support 20 and a sensing component 30 containing a sensor. The support is fixed to a transmission device for the glass substrate. A pin 40 is mounted on the support 20, and the sensing component 30 is rotatably connected to the pin 40. A first magnet 50 is located at the lower end of the sensing component 30, with its S pole facing downwards. A second magnet 60 is also mounted on the support, located below the sensing component, with its N pole facing upwards. When the glass substrate 70 passes through the device, it pushes the sensing component to rotate around the pin. After the glass substrate has completely passed through the device, the sensing component returns to its vertical position under the combined force of its own weight and the attraction of the magnet.
[0004] However, during actual production, a significant defect was discovered in this conventional sensor oscillation device. Because the LCD panel manufacturing process involves multiple chemical treatment steps, the sensor oscillation device needs to be immersed in a chemical environment for extended periods. This unique working environment causes the magnetic force within the sensor oscillation device to gradually weaken. Once the magnetic force weakens, the sensor oscillation device will malfunction. Specifically, during the detection process, delayed rebound, excessively slow swing, or excessive swing amplitude will prevent the device from accurately detecting the position of the glass substrate, leading to an in-service malfunction and system crash. Once a crash occurs, the glass substrate in transit is highly susceptible to transmission abnormalities, ultimately resulting in substrate scrap. This not only wastes raw materials but also significantly increases production costs, severely impacting production efficiency and the company's economic benefits. Utility Model Content
[0005] The technical problem to be solved by this utility model is to provide a novel sensor swing device to reduce the risk of abnormal transmission and scrapping of glass substrates due to magnet deterioration, slow swing, or excessive swing amplitude.
[0006] This utility model is implemented as follows:
[0007] This utility model provides a novel sensor swing device, including a sensing component with a built-in sensor and a bracket fixed on a glass substrate transmission device. A pin is provided on the side wall of the bracket, and the sensing component is rotatably connected to the pin. The lower end of the sensing component has a first magnet with the S pole of the first magnet facing down.
[0008] The bracket has a first protrusion located below the sensing component, and a second magnet is mounted on the first protrusion with the N pole of the second magnet facing upward.
[0009] A third magnet is also provided on the side of the support facing the sensing component. The third magnet corresponds to the lower end of the sensing component, and the N pole of the third magnet faces the sensing component.
[0010] Furthermore, the upper end of the sensing component is provided with a mounting shaft, and the mounting shaft is rotatably connected to a ball bearing.
[0011] Furthermore, a gasket is provided on the outer wall of the pin, and the gasket is disposed between the sensing component and the side wall of the bracket.
[0012] Furthermore, the bracket includes a base, a connecting seat, and a mounting seat;
[0013] The pin, the first boss and the third magnet are all mounted on the mounting base, the connecting seat is vertically mounted on the top of the base, and the base and the connecting seat are integrally formed.
[0014] The connecting seat is provided with a first fixing groove, the length direction of the first fixing groove is extended vertically, the first bolt passes through the first fixing groove and is spirally connected to the mounting seat, the mounting seat is provided with a second protrusion on the side opposite to the first protrusion, the second protrusion is provided with an adjusting bolt, and the adjusting bolt abuts against the top of the connecting seat.
[0015] The base is also provided with a second fixing groove.
[0016] Furthermore, the connecting seat is provided with a guide groove, and the mounting seat is slidably connected in the guide groove.
[0017] The advantages of this utility model are:
[0018] 1. By adding a third magnet to the support, a more stable and powerful oscillation force is provided for the sensing component. Unlike existing technologies where the sensing component experiences oscillation delays or excessive oscillation amplitude due to magnetic decay, this invention enables the sensing component to complete the oscillation action quickly and accurately, effectively avoiding malfunctions caused by abnormal oscillation. This structure ensures that the sensing component maintains a stable working state throughout multiple detection processes, significantly improving the overall reliability of the device and further reducing the risk of transmission abnormalities and scrap due to decreased magnetic properties of the sensing component.
[0019] 2. When the third magnet is assembled, the increased magnetic attraction force can cause the lower end of the sensing component to shift towards the side wall of the bracket under the magnetic force, while the upper end will tilt away from the side wall accordingly, thus hindering the rotation around the pin shaft. By setting a shim to fill the gap between the side wall of the bracket and the sensing component, the tilting problem of the sensing component caused by the increased magnetic attraction force due to the addition of the third magnet can be effectively prevented, making the rotation of the sensing component around the pin shaft smoother.

[0027] Please see Figures 2 to 4This utility model provides a novel sensor swing device, including a sensing component 1 with a built-in sensor, and a bracket 2 fixed on a glass substrate transmission device. A pin 3 is provided on the side wall of the bracket 2. The sensing component 1 is rotatably connected to the pin 3. The lower end of the sensing component 1 has a first magnet 11 with the S pole of the first magnet 11 facing downward.
[0028] The bracket 2 has a first protrusion 21 located below the sensing component 1. A second magnet 4 is mounted on the first protrusion 21, with the N pole of the second magnet 4 facing upward.
[0029] A third magnet 5 is also provided on the side of the support facing the sensing component 1. The third magnet 5 corresponds to the lower end of the sensing component 1, and the N pole of the third magnet 5 faces the sensing component 1. More precisely, the N pole of the third magnet 5 faces the S pole of the first magnet 11 disposed inside the sensing component 1.
[0030] When the glass substrate passes over the device, it comes into contact with the upper end of the sensing component 1. Because the glass substrate is translating, when the glass substrate passes over the sensing component 1, the sensing component 1 rotates around the pin 3, causing the sensing component 1 to sway.
[0031] After the glass substrate passes over the device, the sensing component 1 returns to its vertical position under the gravity of its own weight and the attraction of the second and third magnets 5.
[0032] Compared with existing technologies, by adding a third magnet 5 to the support 2, a more stable and stronger oscillation force is provided for the sensing component 1. Unlike existing technologies where the sensing component 1 experiences oscillation delays or excessive oscillation amplitudes due to magnetic decay, this invention enables the sensing component 1 to complete the oscillation action quickly and accurately, effectively avoiding malfunctions caused by abnormal oscillation. This structure ensures that the sensing component 1 maintains a stable working state throughout multiple detection processes, significantly improving the overall reliability of the device and further reducing the risk of transmission abnormalities and scrap due to decreased magnetism of the sensing component 1.
[0033] Specifically, the upper end of the sensing component 1 is provided with a mounting shaft 6, and a ball bearing 7 is rotatably connected to the mounting shaft 6. When the glass substrate passes through this device, the lower surface of the glass substrate comes into contact with the ball bearing 7.
[0034] Specifically, a shim 8 is also provided on the outer wall of the pin 3, and the shim 8 is disposed between the sensing component 1 and the side wall of the bracket 2. When the third magnet 5 is assembled, the increase in magnetic attraction force can easily cause the lower end of the sensing component 1 to shift towards the side wall of the bracket 2 under the action of magnetic force, while the upper end will tilt in a direction away from the side wall, thereby hindering the rotation around the pin 3. By providing a shim 8 to fill the gap between the side wall of the bracket 2 and the sensing component 1, the tilting problem of the sensing component 1 caused by the increased magnetic attraction force due to the addition of the third magnet 5 can be effectively prevented, making the rotation of the sensing component 1 around the pin 3 smoother.
[0035] Specifically, the bracket 2 includes a base 22, a connecting seat 23, and a mounting seat 24;
[0036] The pin 3, the first boss 21 and the third magnet 5 are all mounted on the mounting base 24, and the connecting seat 23 is vertically mounted on the top of the base 22, and the base 22 and the connecting seat 23 are integrally formed.
[0037] The connecting seat 23 is provided with a first fixing groove 231, the length direction of the first fixing groove 231 extends in the vertical direction, the first bolt 9 passes through the first fixing groove 231 and is spirally connected to the mounting seat 24, the mounting seat 24 is provided with a second boss 241 on the side opposite to the first boss 21, the second boss 241 is provided with an adjusting bolt 10, the adjusting bolt 10 abuts against the top of the connecting seat 23;
[0038] The base 22 is also provided with a second fixing groove 221. The bolts that fix this device pass through the second fixing groove 221 and are locked onto the glass substrate transport equipment.
[0039] After the first bolt 9 is loosened, the mounting base 24 and the connecting base 23 can be slid relative to each other by rotating the adjusting bolt 10. The height of the upper end of the sensing component 1 from the base 22 can be adjusted to accommodate different installation dimensions.
[0040] Specifically, the connecting seat 23 is provided with a guide groove 232, and the mounting seat 24 is slidably connected in the guide groove 232.
[0041] The advantages of this invention are as follows: By adding a third magnet to the support, a more stable and powerful oscillation force is provided for the sensing component. Unlike existing technologies where the sensing component experiences delayed oscillation or excessive oscillation amplitude due to magnetic force decay, this invention enables the sensing component to complete the oscillation action quickly and accurately, effectively avoiding abnormal operation caused by abnormal oscillation. This structure ensures that the sensing component maintains a stable working state during multiple detection processes, significantly improving the overall reliability of the device and further reducing the risk of transmission abnormalities and scrap due to decreased magnetic properties of the sensing component. When the third magnet is installed, the increased magnetic attraction force can easily cause the lower end of the sensing component to shift towards the side wall of the support under magnetic force, while the upper end tilts accordingly away from the side wall, thus hindering the rotation around the pin. By setting a shim to fill the gap between the side wall of the support and the sensing component, the tilting problem of the sensing component caused by the increased magnetic attraction force due to the addition of the third magnet can be effectively prevented, making the rotation of the sensing component around the pin smoother.
