Description

Technical Field

[0001] This invention belongs to the field of transportation equipment technology, and in particular relates to a dual-interface feeding and discharging device for a multi-floor hoist. Background Technology

[0002] In the production and transportation of IC substrates or wafers, cross-floor transport is frequently required. For example, IC substrates or wafers produced on the first floor need to be transported to the second floor for packaging, and then IC substrates or wafers from the second floor need to be transported back to the first floor. However, currently, cross-floor transport of IC substrates or wafers is carried out by operators operating transport trolleys via stairs or elevators, which is not only inefficient but also time-consuming and labor-intensive. In addition, existing cross-floor hoists for IC substrates or wafers often have only one interface on the ground, with both feeding and discharging completed at the same interface. When materials need to enter or exit the interface, materials behind need to queue up, causing congestion and low transportation efficiency. Summary of the Invention

[0003] This invention discloses a dual-interface feeding and discharging device for a cross-floor hoist, which mainly solves the problems of low efficiency, time and labor costs in the current cross-floor transportation of IC carrier boards or wafers.

[0004] To achieve the aforementioned objective, the present invention provides a dual-interface feeding and discharging device for a multi-floor hoist, comprising a mounting frame, wherein the mounting frame is provided with a feeding area and a discharging area, the feeding area and the discharging area being provided with corresponding inlets and outlets, a feeding device is provided in the feeding area, the feeding device comprising a feeding platform and a lifting component disposed within the mounting frame, and a discharging device is provided in the discharging area, the discharging device comprising a transport vehicle and a lifting component disposed within the mounting frame, and a transfer device for transferring between the feeding device and the discharging device is also provided within the mounting frame.

[0005] Preferably, the feeding platform includes a platform body and a boss disposed on the platform body for placing pallets.

[0006] Preferably, the lifting assembly includes two supporting devices and a first driving device for driving the two supporting devices to move up and down. The supporting device includes a connecting plate connected to the first driving device, a support plate connected to the connecting plate, and a support pallet disposed on the support plate and capable of contacting the pallet. The connecting plate is slidably connected to the mounting frame.

[0007] Preferably, the support plate is provided with a left and right positioning device, which includes a movable positioning plate.

[0008] Preferably, the support plate is provided with a front and rear limiting device, which includes a rotatable limiting plate.

[0009] Preferably, the first driving device includes a first motor, a first reducer connected to the first motor, a drive shaft connected to the first reducer, and two drive chains disposed at both ends of the drive rod. The drive chains are connected to a connecting plate. The first motor can drive the drive shaft to rotate. The drive shaft and the drive chains are connected by gear transmission.

[0010] Preferably, the transfer device includes a base slidably mounted on a mounting frame, a second drive device mounted on the base, and a fork assembly driven by the second drive device. The fork assembly includes a slide plate and fork plates slidably mounted on the slide plate. The second drive device includes a second motor and a first drive wheel driven by the second motor. A through groove is provided in the middle of the slide plate, the bottom of the fork plates extends into the groove, and a first rack is provided at the bottom of the fork plates, which is driven by the first drive wheel.

[0011] Preferably, the mounting bracket is provided with a guide rail that is slidably connected to the base, and the base is also provided with a third driving device. The third driving device includes a third motor mounted on the base, a second driving wheel that is driven by the third motor, and a second rack mounted on the mounting bracket and driven by the second driving wheel.

[0012] Preferably, a number of guide wheels are arranged on both sides of the feeding area and the discharging area.

[0013] Preferably, both the feeding platform and the front end of the transport vehicle are equipped with positioning rods.

[0014] The technical solution provided by this invention has at least the following technical effects:

[0015] 1. The dual-interface feeding and discharging device for the cross-floor elevator disclosed in this application can place IC carrier boards or wafers on the feeding platform, then lift them to a certain height through the lifting component, and then transfer the IC carrier boards or wafers to the discharging area through the transfer device. Then, the IC carrier boards or wafers are lifted to the upper floor through the lifting component in the discharging area, thus completing the cross-floor transportation of IC carrier boards or wafers with higher efficiency.

[0016] 2. The feeding area and the discharging area are not fixed for feeding and discharging respectively. The feeding area and the discharging area can be regarded as two transportation areas. Depending on the situation, they can be selectively used for cross-floor feeding or discharging transportation. Therefore, the discharging port and the feeding port form a dual-interface transportation system. Either interface can be selected for feeding or discharging, or feeding or discharging can be done simultaneously. There will be no queuing or congestion. Compared with a single feeding or discharging port, the transportation efficiency is higher. Attached Figure Description

[0027] Reference Figure 1 , Figure 2 This embodiment discloses a dual-inlet feeding and discharging device for a multi-floor hoist, including a mounting frame 1. The mounting frame 1 is provided with a feeding area and a discharging area. The feeding area and the discharging area are respectively provided with a feeding port 2 and a discharging port 3. A feeding device is provided in the feeding area. (Refer to...) Figure 3 The feeding device includes a feeding platform 4 and a lifting assembly 5 installed in the mounting frame 1. The feeding platform 4 includes a platform body 41 and a boss 42 for placing the pallet 22 on the platform body 41. The entire platform body 41 is square. Guide wheels 6 are provided on both sides of the feeding area. Under the guidance of the guide wheels 6, the boss 42 moves more stably when pushed into the feeding area and will not deviate. At the same time, a positioning rod 7 is provided at the front end of the platform body 41. The number of positioning rods 7 is set according to the actual situation. In this embodiment, there are two positioning rods 7, located on both sides of the platform body 41. When the platform body 41 is pushed into the feeding area, the positioning of the platform body 41 is completed until the positioning rod 7 abuts against the mounting frame 1. In this embodiment, the boss 42 is circular and the width of the boss 42 is smaller than the width of the platform body 41. When the pallet 22 is placed on the boss 42, the two sides of the pallet 22 are suspended.

[0028] Reference Figure 4The discharge area is equipped with a discharge device, which includes a transport vehicle 8 installed in the mounting frame 1 and a lifting component 5 installed in the mounting frame 1. Several guide wheels 6 are provided on both sides of the discharge area. Under the guidance of the guide wheels 6, the transport vehicle 8 moves more stably when pushed into the feeding area and will not deviate. A positioning rod 7 is provided at the front end of the transport vehicle 8. The number of positioning rods 7 is set according to the actual situation. In this embodiment, there are two positioning rods 7, located on both sides of the transport vehicle 8. When the transport vehicle 8 is pushed into the feeding area, the positioning of the transport vehicle 8 is completed until the positioning rod 7 abuts against the mounting frame 1. The transport vehicle 8 is equipped with a shelf for placing pallets 22. When the pallets 22 are placed on the shelf, the sides are also in a suspended state.

[0029] Sensing devices are provided between the platform 41 and the mounting frame 1, and between the transport vehicle 8 and the mounting frame 1. The sensing devices include a mounting plate 9 installed on the platform 41 or the transport vehicle 8, and a sensor 10 installed on the mounting plate 9. The sensor 10 senses the sensing element on the mounting frame 1 to realize the sensing and positioning between the platform 41, the transport vehicle 8 and the mounting frame 1. When the sensing platform 41 or the transport vehicle 8 moves to the designated position, the locking mechanism is controlled by the PLC to lock and position it. The sensing of the specific sensor and the structure of the locking mechanism adopt common sensing devices and locking devices in the art. Their working principle is not described in detail in this embodiment.

[0030] Reference Figure 3 , Figure 4 The lifting assembly 5 includes two supporting devices (the two supporting devices are located on both sides of the feeding area or the discharging area) and a first driving device for driving the two supporting devices to move up and down. The two supporting devices are used to support both sides of the pallet 22 and lift the pallet 22. Each supporting device includes a connecting plate 51 connected to the first driving device, a support plate 52 connected to the connecting plate 51, and a support tray 53 disposed on the support plate 52 and in contact with the pallet 22. The connecting plate 51 is slidably connected to the mounting frame 1. The first driving device includes a first motor 54, a first reducer driven by the first motor 54, a drive shaft driven by the first reducer, and two drive chains 56 disposed at both ends of the drive rod. The drive chains 56 are connected to the connecting plate 51. The first motor 54 can drive the drive shaft to rotate. The drive shaft and the drive chains 56 are connected by gear transmission. The first motor 54 can drive the rotating shaft 55 to rotate via a reducer. The rotating shaft 55 can drive the transmission chain 56 to rotate via gears. Since the transmission chain 56 is connected to the connecting plate 51 and the connecting plate 51 is slidably connected to the mounting bracket 1, the connecting plate 51 can be moved up and down during the rotation of the transmission chain 56. In turn, the pallet 22 can be moved up and down via the support tray 53 to lift the IC carrier board or wafer.

[0031] When the IC carrier board or wafer disk is located on the support tray 53 of the support device, in order to improve the stability of the pallet 22, a left and right positioning device is provided on the support plate 52. The left and right positioning device includes a movable positioning plate 11. Each support plate 52 is provided with two positioning plates 11. The positioning plates 11 can be driven by, but are not limited to, a cylinder. The positioning plates 11 can be driven by a cylinder to abut against the pallet 22. Under the action of the positioning plates 11 on both sides, the left and right sides of the pallet 22 are positioned.

[0032] A front and rear limiting device is provided on the support plate 52, which includes a rotatable limiting plate 12. The limiting plate 12 can be driven by a motor, but is not limited to a motor, which drives the limiting plate 12 to rotate 90° to limit the pallet 22.

[0033] Reference Figure 5 The mounting frame 1 is further equipped with a transfer device for transferring IC carrier boards or wafers between the feeding device and the discharging device. The transfer device is used for transporting IC carrier boards or wafers between the feeding device and the discharging device. The transfer device includes a base 13 slidably mounted on the mounting frame 1, a second drive device mounted on the base 13, and a fork assembly driven by the second drive device. The fork assembly includes a slide plate 15 and fork plates 16 slidably mounted on the slide plate 15. The second drive device includes a second motor 14 and a first drive wheel (not shown) driven by the second motor 14. The slide plate 15 has a through groove 151 in the middle. The bottom of the fork plate 16 extends into the groove 151, and the bottom of the fork plate 16 has a first rack (not shown) driven by the first drive wheel. The first drive wheel is rotated by the second motor 14, which in turn drives the fork plate 16 to move via the first rack, thus achieving the extension and retraction of the fork plate 16. The mounting frame 1 is provided with a guide rail 17 slidably connected to the base 13. The base 13 is also provided with a third drive device, which includes a third motor 18 mounted on the base 13, a second drive wheel (not shown) driven by the third motor 18, and a second rack 19 mounted on the mounting frame 1 and driven by the second drive wheel. Driven by the third motor 18, the entire rotating device can move left and right on the guide rail 17 through the cooperation between the second drive wheel and the second rack 19. Foldable protective covers are provided on both sides of the base 13 for dust protection. Both the first rack and the second rack 19 are helical gear structures, resulting in better transmission. It should be noted that the transmission structure of racks and gears is well known to those skilled in the art and will not be described in detail in this embodiment.

[0034] Working Principle: In this embodiment, both the feeding area and the discharging area span two floors. When it is necessary to transfer IC carrier boards or wafers to the upper floor, the feeding platform 4 is pushed into the feeding area until the positioning rod 7 on the platform 41 abuts against the mounting frame 1, completing the positioning of the feeding platform 4. At the same time, the sensor 10 on the platform 41 senses the mounting frame 1, realizing the sensing positioning between the feeding platform 4 and the mounting frame 1. At this time, the position of the support trays 53 on both sides of the feeding area is lower than the position of the boss 42. The pallet 22 containing IC carrier boards or wafers is placed on the boss 42. Then, the lifting component 5 is activated, and the support tray 53 abuts against the bottom of the pallet 22, lifting the pallet 22. The cylinder pushes the positioning plates 11 on both sides to move. The pallet 22 is clamped from left to right, while the motor drives the limiting plate 12 to rotate, limiting the front and rear movement of the pallet 22. The first motor 54 drives the rotating shaft 55 to rotate through the reducer, and then drives the transmission chain 56 to rotate through the rotating shaft 55. The rotation of the transmission chain 56 will cause the connecting plate 51 to slide upward on the mounting frame 1, lifting the pallet 22 to a certain height. Then, the fork plate 16 of the rotating device extends into the feeding area under the transmission action of the second motor 14 and the first rack, and extends to the lower end of the pallet 22. After that, the two supporting devices drive the pallet 22 to move downward, and the pallet 22 is directly placed on the fork plate 16. There is no need for additional personnel or equipment to move the pallet to the fork plate 16, which is more efficient.

[0035] Then, the positioning plate 11 and the limiting plate 12 reset, and the second motor 14 drives the fork plate 16 and the pallet 22 to reset. Then, through the cooperation of the third motor 18 and the second rack 19, the pallet 22 moves left and right, moving to the corresponding position in the discharge area. Then, the second motor 14 is driven again, causing the fork plate 16 and the pallet 22 to extend into the discharge area. Specifically, the fork plate 16 can be driven to move on the slide plate 15 via the second drive device. When loading is required, the fork plate 16 can be driven to extend forward, allowing... The IC carrier board or wafer falls directly onto the fork plate 16, and then the fork plate 16 is driven to retract. After that, the base 13 is driven to move on the guide rail to transport the IC carrier board or wafer to the unloading area. Finally, the fork plate 16 is driven by the second drive device to move the IC carrier board or wafer forward, so that the IC carrier board or wafer falls onto the lifting component in the unloading area, which is more efficient. At this time, the pallet 53 in the unloading area is located below the pallet 22. The lifting component 5 in the unloading area lifts the pallet 22 upward in the unloading area to the upper floor.

[0036] When IC substrates or wafers processed on the upper floor need to be transferred to the lower floor, the pallet 22 containing the IC substrates or wafers can be placed on the lifting component 5 in the feeding area. The lifting component will lower the pallet 22 until it is placed on the transport vehicle 8. Then, the transport vehicle 8 can be pulled out directly to remove the IC substrates or wafers, making the cross-floor transportation of IC substrates or wafers more efficient. In this embodiment, a sealing plate assembly is provided at both the feeding port 2 and the discharging port 3. The sealing plate assembly includes a sealing plate 20 that is slidably connected to the mounting frame 1 and a lifting cylinder 21 that is vertically mounted on the mounting frame 1. The output end of the lifting cylinder 21 is connected to the sealing plate 20. The lifting cylinder 21 drives the sealing plate 20 to move up and down, thereby opening and closing the feeding port 2 and the discharging port 3.

[0037] The infeed and outfeed areas are not fixed to be used for feeding and discharging respectively. They can be considered two separate transport zones, which can be selectively used for cross-floor feeding or discharging depending on the situation. For example, both areas can be used for cross-floor feeding, transporting IC substrates or wafers from lower floors to higher floors; conversely, both can be used for cross-floor discharging, transporting IC substrates or wafers from higher floors to lower floors. This avoids queuing or congestion and offers higher transport efficiency compared to single-infeed / discharge ports.

[0038] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
