[0002] The aerial track system in an automatic production workshop such as a wafer processing workshop is composed of a large number of interlaced tracks. The aerial track system can be used for the crown block to run thereon to transfer materials.

[0003] As shown in Figure 1 Each track system of each workshop needs at least one reserved interface, which is a track gap, to prepare for the prevention of newly added equipment laying tracks and to be used as a feeding port for the crown block when the track is just laid.

[0004] However, the existence of the above-mentioned reserved interface causes the risk of the crown block rushing out of the reserved interface when the crown block runs on the track system. If the crown block rushes out, it will cause damage to the crown block and the wafer pieces in the wafer box carried by the crown block. CONTENT OF THE INVENTION

[0005] Therefore, it is necessary to provide a track protection system for a crown block running to solve the problem of the risk of the crown block rushing out when the crown block runs on the track.

[0035] As shown in Figure 2 , the present application proposes a track protection system 100 for the operation of a crown block 300, to prevent the crown block 300 running on the track system 200 from rushing out of the broken rail port 2111.

[0036] For ease of understanding, first, the track system 200 involved in the present application will be briefly described.

[0037] Referring to Figures 2 to 4 , the track system 200 involved in the present application includes straight rails 210 and curved rails 220 connected to the straight rails 210. In the walking direction defined by the straight rails 210, the straight rails 210 on the first side of the curved rails 220 are provided with a reserved straight section 211 including a broken rail port 2111, and the straight rails 210 on the second side of the curved rails 220 are provided with a conventional straight section 212. The walking direction defined by the straight rails 210 is the extension direction of the straight rails 210.

[0038] Specifically, referring to Figure 2 , the straight rails 210 on the left side of the curved rails 220 are the reserved straight sections 211 including the broken rail ports 2111, and the straight rails 210 on the right side of the curved rails 220 are the conventional straight sections 212. The broken rail port 2111 can be used as a reserved interface.

[0039] Optionally, the curved rails 220 connect two straight rails 210 arranged in parallel. Each straight rail 210 is provided with a broken rail port 2111, and the broken rail ports 2111 of the two straight rails 210 are located on the same side of the curved rails 220. Figure 2 In the present application, both broken rail ports 2111 are located on the left side of the curved rails 220.

[0040] The straight rail 210 comprises an outer straight section 213 and an inner straight section 214, and the outer straight section 213 and the inner straight section 214 are connected by at least one rail connector 230. In the transverse direction, the inner straight section 214 is closer to the curved rail 220 relative to the outer straight section 213.

[0041] Specifically, with reference to Figure 2 In the present application, the transverse direction is the width direction of the straight rail 210, and is also the arrangement direction of the outer straight section 213 and the inner straight section 214 in the straight rail 210. The transverse direction and the walking direction defined by the straight rail 210 are perpendicular to each other in the horizontal direction.

[0042] The rail connector 230 can be in a U shape. In the reserved straight section 211 of the straight rail 210, the outer straight section 213 and the inner straight section 214 are connected by at least one rail connector 230. In the regular straight section 212 of the straight rail 210, the outer straight section 213 and the inner straight section 214 are also connected by at least one rail connector 230. The rail connectors 230 on the reserved straight section 211 and the regular straight section 212 are located on both sides of the curved rail 220 in the walking direction defined by the straight rail 210.

[0043] The curved rail 220 comprises an outer curved section 221, an inner curved section 222, and a curved guide strip 223. The outer curved section 221 and the inner curved section 222 are connected to the inner straight section 214. Further, the outer curved section 221 and the outer straight section 213 can also be connected by a rail connector 230.

[0044] In the arrangement direction of the outer curved section 221 and the inner curved section 222, the curved guide strip 223 is located between the outer curved section 221 and the inner curved section 222, and the radius of curvature of the curved guide strip 223 is greater than the radius of curvature of the inner curved section 222 and less than the radius of curvature of the outer curved section 221. The curved guide strip 223 can be mounted to a connecting plate 240. The connecting plate 240 can be connected to the rail connector 230, for example. The connecting plate 240 can be used to hoist to the ceiling when the rail system 200 is installed.

[0045] The overhead crane 300 can switch to a different straight rail 210 through the transition of the curved rail 220 to change the walking direction. Specifically, when the overhead crane 300 just enters or exits the curved rail 220, the inner walking wheels 320 of the overhead crane 300 abut and roll on the top surface of the inner curved section 222, and the steering wheels 131 on the overhead crane 300 abut the inner wall of the curved guide strip 223, so that the outer walking wheels 320 of the overhead crane 300 do not contact the top surface of the outer curved section 221, thereby completing the turning. The inner side of the inner curved section 222 and the inner wall of the curved guide strip 223 face each other.

[0046] The track protection system 100 includes a blocking device 110, a turning guide 120, and a turning device 130.

[0047] Referring to Figures 2 to 5 The blocking device 110 is fixed to the reserved straight section 211. The blocking device 110 is used to mechanically protect the trolley 300 from being knocked out of the track break 2111 when the trolley 300 runs on the straight track 210. The blocking device 110 can be arranged at the track break 2111 of the reserved straight section 211, or at the turnout formed by the reserved straight section 211 and the curved track 220.

[0048] The turning guide 120 is fixed above the conventional straight section 212. The turning guide 120 is used to guide the trolley 300 to turn.

[0049] The turning device 130 includes a turning wheel 131 arranged on the trolley 300. The turning wheel 131 is configured to be movable in the transverse direction to be adjusted to a guide matching position. When the turning wheel 131 is in the guide matching position, the turning wheel 131 can cooperate with the turning guide 120 when the trolley 300 advances along the conventional straight section 212 to make the trolley 300 turn into the curved track 220. The transverse direction and the walking direction are perpendicular to each other in the horizontal direction.

[0050] Further, the turning device 130 can further include a dial mechanism (not shown). The dial mechanism is in transmission connection with the turning wheel 131 to realize manual or automatic control of the turning wheel 131 to switch between the guide matching position and other positions.

[0051] Specifically, referring to Figure 2 , the trolley 300 is shown to normally walk on the conventional straight section 212 of the straight track 210.

[0052] As shown in Figure 3 and Figure 5 , when the trolley 300 walks to the turnout formed by the curved track 220 and the straight track 210 and the turning wheel 131 is in the guide matching position, if the trolley 300 continues to walk, the turning wheel 131 moves under the guidance of the turning guide 120, and then the turning wheel 131 presses the curved section guide strip 223 and moves along the track defined by the curved section guide strip 223.

[0053] Referring to Figure 4 , if the turning wheel 131 does not timely turn to the guide matching position, the trolley 300 fails to turn and continues to walk along the straight track 210. When the trolley 300 walks to the track break 2111, it is blocked by the blocking device 110 and will not be knocked out of the track break.

[0054] In the present application, the turning guide 120 is arranged to enable the crane 300 to smoothly turn; meanwhile, the blocking device 110 is arranged at the broken rail opening 2111, which can avoid the crane 300 from rushing out along the straight rail 210 when the turning fails. Specifically, when the crane 300 is running at high speed along the straight rail 210, the turning guide 120 can guide the crane 300 to smoothly turn, and the risk of the crane 300 rushing out along the straight rail 210 can be avoided; when the crane 300 continues to run along the straight rail 210 due to the turning failure, the blocking device 110 can block the crane 300 from rushing out of the straight rail 210 from the broken rail opening 2111, thereby avoiding the damage of the crane 300 and the wafer pieces in the wafer box carried by the crane 300.

[0055] In some embodiments, referring to 2, Figure 3 and Figure 6 The turning guide 120 has an arc-shaped end 121, and the guide track of the arc-shaped end 121 is located on the extension line of the curved section guide strip 223 or is tangent to the curved section guide strip 223.

[0056] Specifically, in the present application, the arc-shaped end 121 is located on one side of the curved section guide strip 223, and the two have a small interval, so that when the turning wheel 131 abuts against the arc-shaped end 121, the turning wheel 131 can smoothly transition to abut against the curved section guide strip 223.

[0057] In other embodiments, the arc-shaped end 121 and the curved section guide strip 223 can also be tangent to each other, so that the turning wheel 131 can also smoothly transition to abut against the curved section guide strip 223. At this time, the arc-shaped end 121 and the curved section guide strip 223 as a whole present an S shape.

[0058] Referring to Figure 6 The turning guide 120 is fixed to a rail connecting piece 230. The rail connecting piece 230 specifically presents a U shape, and two ends thereof are respectively connected to the inner straight section 214 of the straight rail 210 and the inner curved section 222 of the curved rail 220. One end of the turning guide 120 has the above-mentioned arc-shaped end 121, and the other end is fixed to the middle part of the rail connecting piece 230. In this way, the turning guide 120 is suspended above the straight rail 210, and the turning guide 120 is located between the inner straight section 214 and the outer straight section 213.

[0059] Optionally, the other end of the turning guide 120 is fixed to the middle part of the rail connecting piece 230 by means of, for example, clamping, bolt connection, etc.

[0060] In some embodiments, referring to Figure 7 and Figure 8The blocking device 110 comprises a fixed plate 111, a first blocking block 112 and a second blocking block 113, wherein the fixed plate 111 is fixed to at least one of the straight rail 210 or the curved rail 220, the first blocking block 112 is above the outer straight section 213, and the second blocking block 113 is above the inner straight section 214.

[0061] The outer straight section 213 is used to support the outer traveling wheels 310 of the crown block 300, and the inner straight section 214 is used to support the inner traveling wheels 320 of the crown block 300. The first blocking block 112 is used to block the outer traveling wheels 310 of the crown block 300, and the second blocking block 113 is used to block the inner traveling wheels 320 of the crown block 300. In this way, if the crown block 300 travels along the straight rail 210 and rushes to the broken rail opening 2111, the outer traveling wheels 310 and the inner traveling wheels 320 of the crown block 300 will be blocked by the first blocking block 112 and the second blocking block 113 respectively, so as not to rush out of the straight rail 210.

[0062] Optionally, the blocking device 110 is arranged at the broken rail opening 2111. Specifically, referring to Figure 7 and Figure 8 , the two ends of the fixed plate 111 are respectively overlapped and fixed on the outer straight section 213 and the inner straight section 214. The first blocking block 112 and the second blocking block 113 are respectively located on the top surface of the two end portions of the fixed plate 111. In this way, the first blocking block 112 is above the outer straight section 213, and the second blocking block 113 is above the inner straight section 214.

[0063] In other embodiments, the blocking device 110 can also be arranged at the position where the reserved straight section 211 and the curved rail 220 form a turnout. Specifically, as shown in Figure 9 , the two ends of the fixed plate 111 are overlapped and fixed on the outer straight section 213 and the outer curved section 221.

[0064] In other embodiments, the fixed plate 111 of the blocking device 110 can also be arranged at any position between the broken rail opening 2111 and the curved rail 220.

[0065] In other embodiments, referring to Figure 7 and Figure 8 , the fixed plate 111 is provided with a first clamping block 114 and a second clamping block 115, and the first clamping block 114 and the second clamping block 115 are respectively connected to the rail connecting piece 230 in the transverse direction.

[0066] In this embodiment, the blocking device 110 can also be fixed to the rail connector 230 by the first clamping block 114 and the second clamping block 115. The fixing plate 111 can be used to abut against the straight rail 210 or the curved rail 220, and can not be connected to the straight rail 210 or the curved rail 220, thereby providing more options for the connection of the blocking device 110. The first clamping block 114 and the second clamping block 115 can be, for example, respectively connected to the rail connector 230 by clamping, or the first clamping block 114 and the second clamping block 115 can clamp the rail connector 230 from both sides.

[0067] Further, referring to Figure 7 , the first blocking block 112 and the second blocking block 113 are respectively provided with an elastic portion 116 on the side facing the curved rail 220. The elastic portion 116 has a buffering function when blocking the cage 300, thereby avoiding rigid impact and damaging the two running wheels of the cage.

[0068] Taking the first blocking block 112 as an example, the elastic portion 116 is, for example, an elastic layer fixed on the first blocking block 112. Alternatively, the first blocking block 112 is made of an elastic material as a whole, so that the side of the first blocking block 112 facing the curved rail 220 forms the above-mentioned elastic portion 116.

[0069] In some embodiments, referring to Figure 2 , Figure 7 The rail protection system 100 further includes an obstacle function plate 140 connected to the blocking device 110, and an obstacle detection assembly 330 provided on the cage 300.

[0070] The obstacle detection assembly 330 is used to detect the relative position of the obstacle function plate 140 and the cage 300, so that the control system can control the cage 300 to execute instructions such as deceleration in advance and stopping. In this way, the obstacle function plate 140 and the obstacle detection assembly 330 provide a hardware basis for protecting the cage 300 by using software programs.

[0071] Specifically, the obstacle detection assembly 330 monitors and feeds back the distance from the obstacle to the cage 300 in real time. When the obstacle is detected, the control system can determine whether to execute instructions such as deceleration in advance and stopping according to the current speed of the cage 300 and a preset control strategy.

[0072] Alternatively, the obstacle function plate 140 is provided with a range finder reflective portion 141 and a radar light blocking portion 142. The obstacle detection assembly 330 includes a range finder 331 and a radar 332.

[0073] The distance measuring instrument 331 is used in cooperation with the distance measuring instrument light reflection part 141. The distance measuring instrument 331 is specifically a laser distance measuring instrument, and the distance measuring instrument light reflection part 141 is specifically a region formed by pasting a light reflection sticker. The laser distance measuring instrument 331 can sense the light reflection sticker within a certain range, so that the control system can control the overhead traveling crane 300 to slow down in advance.

[0074] For example, the laser distance measuring instrument 331 is configured to be able to sense the light reflection sticker within a range of 10 m. A software program will in advance inform the overhead traveling crane 300 to prepare to slow down, and the overhead traveling crane 300 is slowed down from high speed to medium speed within a distance of 8 m and 4 m from the broken rail, and the overhead traveling crane 300 is slowed down from medium speed to low speed within a distance of 4 m and 2 m from the broken rail opening 2111 for turning; preventing the overhead traveling crane 300 from running at high speed and not being able to turn in time when approaching the broken rail opening 2111 and colliding with the broken rail.

[0075] The radar 332 can be a laser radar. The laser radar is used to detect the radar light blocking part 142, and the two are cooperated to effectively prevent the distance measuring instrument 331 from being unable to slow down in advance or stop urgently due to the blind area of the field of view not being irradiated to the light reflection part. The radar 332 irradiates and scans the radar light blocking part 142 to obtain the position of the blocking device 110, and has the advantage of a large detection area.

[0076] In the present application, the obstacle function plate 140 is arranged on the blocking device 110, and is used in cooperation with the distance measuring instrument 331 and the radar 332. On the one hand, the distance measuring instrument 331 is used to detect the distance, and on the other hand, the radar 332 is used to detect the area, so that the obstacle detection assembly 330 can timely detect the position information of the obstacle function plate 140 and the blocking device 110, thereby providing reliable data support for the control system to control the overhead traveling crane 300 to slow down in advance and stop.

[0077] Optionally, referring to Figure 2 , Figure 7 and Figure 8 , the obstacle function plate 140 is located below the straight rail 210, the distance measuring instrument light reflection part 141 and the radar light blocking part 142 are arranged in an up-down manner in the vertical direction, and the distance measuring instrument 331 and the radar 332 are arranged on the front side of the overhead traveling crane 300 in the traveling direction.

[0078] The front side of the overhead traveling crane 300 in the traveling direction refers to the side closer to the front in the traveling direction of the overhead traveling crane 300.
