Description

Technical Field

[0001] The present application relates to the field of photovoltaic cell production, and more specifically to a falling-prevention basket lifting mechanism and a basket conveying device. Background Art

[0002] During the process of receiving silicon wafers or other wafers, the full baskets filled with wafers on the full basket buffer conveyor line need to be transferred to the AGV car in the back-end, and the AGV car will transfer the full baskets to the material-using station in the back-end. In addition, it is necessary to receive the empty baskets returned by the AGV car and send them to the empty basket buffer conveyor line.

[0003] In order to save space, the full basket buffer conveyor line and the empty basket buffer conveyor line are generally arranged in upper and lower layers. Therefore, it is necessary to connect the full basket buffer conveyor line and the empty basket buffer conveyor line through a basket lifting mechanism to realize the exchange of baskets between the AGV trolley and the full basket buffer conveyor line and the empty basket buffer conveyor line.

[0004] The existing material basket lifting mechanism has the problem that when the lifting drive system thereof fails, it is easy to cause the basket to fall, thereby causing safety accidents and damage to the sheet body. Utility Model Content

[0005] In order to solve the above technical problems, the present application provides a falling-proof basket lifting mechanism, which adopts the following technical solutions:

[0006] A falling-prevention basket lifting mechanism comprises a frame, an inspection door, a lifting drive mechanism, a conveying mechanism and an anti-falling latch, wherein:

[0007] An installation space is provided in the frame, the conveying mechanism is located in the installation space and is transmission-connected with the lifting drive mechanism installed on the frame, the conveying mechanism is used to carry and convey the material basket, and the lifting drive mechanism is used to drive the conveying mechanism to lift;

[0008] The inspection door can be installed on the frame in an openable and closable manner. When the inspection door is opened, the installation space is opened. An avoidance hole is provided on the inspection door.

[0009] The rack is provided with a plug-in hole corresponding to the avoidance hole, and the plug-in hole is located on the inner side of the inspection door;

[0010] The anti-falling latch is configured to be inserted into the insertion hole through the avoidance hole, and to extend through the insertion hole to the bottom of the conveying mechanism;

[0011] The anti-falling pin is used to support the falling conveying mechanism.

[0012] The anti-fall material basket lifting mechanism provided in the present application can insert the anti-fall pin into the plug-in hole through the avoidance hole before opening the inspection door. In this way, when the lifting drive mechanism fails and causes the conveying mechanism to fall accidentally, the conveying mechanism is blocked and supported by the anti-fall pin, thereby preventing the conveying mechanism from falling, avoiding safety accidents when opening the inspection door, and avoiding damage to the sheet body.

[0013] In some embodiments, a blocking plate is provided on the conveying mechanism; the anti-falling pin passes through the plug hole and extends to the bottom of the blocking plate, and the anti-falling pin blocks and supports the conveying mechanism through the blocking plate.

[0014] By arranging a blocking plate extending toward the inspection door on the conveying mechanism, when the conveying mechanism accidentally falls, the blocking plate is blocked and supported on the anti-falling latch, thereby preventing the conveying mechanism from falling.

[0015] In some embodiments, a plurality of avoidance holes are provided on the inspection door in the vertical direction, and a plurality of plug-in holes corresponding to the avoidance holes are provided on the frame; the anti-falling latch is configured to be laterally plugged into the corresponding target plug-in hole through the avoidance hole located below the blocking plate, and the distance between the target plug-in hole and the blocking plate is less than a predetermined value.

[0016] When the distance between the target plug hole and the blocking plate is too large, the speed of the conveying mechanism falling to the height of the target plug hole is too large, resulting in the anti-falling pin inserted into the target plug hole being unable to effectively block the conveying mechanism. However, by providing a plurality of avoidance holes arranged in the vertical direction on the inspection door, and providing a plurality of plug holes corresponding to the avoidance holes on the rack, the anti-falling pin can be inserted into the appropriate avoidance hole and plug hole according to the height of the conveying mechanism, ensuring that the anti-falling pin can effectively block the falling conveying mechanism.

[0017] In some embodiments, a sensor connected to the controller signal of the inspection door is provided on the blocking plate; after the anti-falling pin is inserted into the target plug hole, the sensor is triggered to generate a door opening signal, and the door opening signal is provided to the controller of the inspection door to trigger the controller to unlock the inspection door.

[0018] Ensure that the inspection door can be opened only after the anti-falling pin is inserted into the target plug hole. Prevent the inspection door from being opened without the anti-falling pin inserted, causing safety accidents.

[0019] In some embodiments, the sensor includes a proximity switch or a photoelectric switch.

[0020] Two sensors with simple structure and sensitive response are provided to ensure that after the anti-falling bolt is plugged into the target plug hole, the sensor can be triggered to generate a door opening signal.

[0021] In some embodiments, a plug board extending in the vertical direction is disposed on the rack, and a plurality of plug holes are equidistantly disposed on the plug board in the vertical direction.

[0022] By providing a plug-in board extending in the vertical direction, it is convenient to provide a plurality of plug-in holes arranged in the vertical direction on the rack.

[0023] In some embodiments, the lifting drive mechanism includes a brake motor, a screw and a screw nut, wherein: the brake motor is arranged on a frame, one end of the screw is connected to the driving end of the brake motor, the other end of the screw is rotatably connected to the frame, and the screw nut is screwed on the screw and fixed on the conveying mechanism; the brake motor drives the screw to rotate to drive the conveying mechanism to lift and lower through the screw nut.

[0024] By configuring the lifting drive mechanism to include a brake motor, a lead screw and a lead screw nut, the lifting drive mechanism can drive the conveying mechanism to lift and lower stably and slowly. In addition, by using a brake motor as a driving component, when the conveying mechanism accidentally falls, the brake motor can brake, thereby further reducing the risk of the conveying mechanism falling.

[0025] In some embodiments, the access door is a transparent door panel.

[0026] The inspection door is set as a transparent door panel to facilitate observation of the height of the conveying mechanism, thereby ensuring that appropriate avoidance holes and plug-in holes can be selected to insert the anti-fall pin.

[0027] The present application also provides a basket conveying device, which includes a full basket buffer conveyor line, an empty basket buffer conveyor line, an AGV trolley and the anti-fall basket lifting mechanism described in any of the above items, wherein: the full basket buffer conveyor line and the empty basket buffer conveyor line are arranged in upper and lower layers; the anti-fall basket lifting mechanism is located at the rear of the full basket buffer conveyor line and the empty basket buffer conveyor line, and the AGV trolley is located at the rear of the anti-fall basket lifting mechanism; the lifting drive mechanism is configured to drive the conveying mechanism to lift and lower so that the conveying mechanism is docked with the full basket buffer conveyor line or with the empty basket buffer conveyor line; when the conveying mechanism is docked with the full basket buffer conveyor line, the conveying mechanism receives the full basket conveyed by the full basket buffer conveyor line and conveys the full basket to the AGV trolley; when the conveying mechanism is docked with the empty basket buffer conveyor line, the conveying mechanism conveys the empty basket received from the AGV trolley to the empty basket buffer conveyor line.

[0028] Through the cooperation of the full basket buffer conveyor line, the empty basket buffer conveyor line, the AGV trolley and the anti-fall basket lifting mechanism, the basket conveying device realizes the exchange of baskets between the AGV trolley and the full basket buffer conveyor line and the empty basket buffer conveyor line.

[0038] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0039] like Figures 1 to 5 As shown, the anti-falling basket lifting mechanism in the embodiment of the present application includes a frame 1, an inspection door 2, a lifting drive mechanism 3, a conveying mechanism 4 and an anti-falling latch 5, wherein:

[0040] An installation space A is provided in the frame 1, and the conveying mechanism 4 is located in the installation space A and is transmission-connected to the lifting drive mechanism 3 installed on the frame 1. The conveying mechanism 4 is used for carrying and conveying the material basket, and the lifting drive mechanism 3 is used for driving the conveying mechanism 4 to lift and lower.

[0041] The inspection door 2 is installed on the frame 1 in an openable and closable manner. When the inspection door 2 is opened, the installation space A is exposed. An avoidance hole 6 is provided on the inspection door 2.

[0042] The rack 1 is provided with a plugging hole 7 corresponding to the avoidance hole 6 , and the plugging hole 7 is located on the inner side of the inspection door 2 .

[0043] The anti-falling latch 5 is configured to be inserted into the insertion hole 7 through the avoidance hole 6 and extend through the insertion hole 7 to directly below the conveying mechanism 4 .

[0044] The anti-falling latch 5 is used to support the falling conveying mechanism 4 .

[0045] The anti-falling basket lifting mechanism of the embodiment of the present application can insert the anti-falling latch 5 into the plug hole 7 through the avoidance hole 6 before opening the inspection door 2. Since the anti-falling latch 5 inserted into the plug hole 7 extends directly below the conveying mechanism 4, when the lifting drive mechanism 3 fails and causes the conveying mechanism 4 to fall accidentally, the conveying mechanism 4 is finally blocked and supported by the anti-falling latch 5, thereby preventing the conveying mechanism 4 from falling, avoiding safety accidents when opening the inspection door 2, and avoiding damage to the sheet body.

[0046] Since the distance between the conveying mechanism 4 and the inspection door 2 is relatively large, in order to ensure that the anti-falling latch 5 can implement blocking support for the falling conveying mechanism 4. Figure 5 As shown, optionally, a blocking plate 8 is provided on the conveying mechanism 4. The anti-falling plug 5 passes through the plug hole 7 and then extends to the bottom of the blocking plate 8, and the anti-falling plug 5 blocks and supports the conveying mechanism 4 through the blocking plate 8. The cross section of the anti-falling plug 5 is rectangular, and the contact area between the rectangular anti-falling plug 5 and the blocking plate 8 is large. The avoidance hole 6 and the plug hole 7 are both rectangular holes, which can effectively prevent the anti-falling plug 5 from rotating, and has good stability and anti-falling effect.

[0047] The conveying mechanism 4 carrying the material basket is heavy. When the distance between the plug hole 7 to which the anti-fall pin 5 is inserted and the blocking plate 8 on the conveying mechanism 4 is too large, the impact force when the conveying mechanism 4 falls to the height of the anti-fall pin 5 is too large. Ultimately, the anti-fall pin 5 cannot effectively block the conveying mechanism 4.

[0048] In order to solve this problem, optionally, a plurality of avoidance holes 6 are provided on the inspection door 2 along the vertical direction, and a plurality of plug-in holes 7 corresponding to the avoidance holes 6 are provided on the frame 1 .

[0049] By providing a plurality of avoidance holes 6 arranged in the vertical direction on the inspection door 2, and providing a plurality of plug-in holes 7 corresponding to the avoidance holes 6 on the frame 1, suitable avoidance holes 6 and plug-in holes 7 can be selected to insert the anti-falling plug 5 according to the current height of the conveying mechanism 4. In this way, the distance between the plug-in hole 7 with the anti-falling plug 5 plugged in and the blocking plate 8 can be made less than a predetermined value, thereby ultimately ensuring that the anti-falling plug 5 can effectively block the falling conveying mechanism 4.

[0050] Optionally, the inspection door 2 is a transparent door panel. By setting the inspection door 2 as a transparent door panel, it is easy to observe the current height of the conveying mechanism 4, so as to ensure that a suitable avoidance hole 6 and plug hole 7 can be selected to insert the anti-falling plug 5, and ensure that the distance between the plug hole 7 plugged with the anti-falling plug 5 and the blocking plate 8 is less than a predetermined value.

[0051] like Figure 5 As shown, optionally, a sensor 10 connected to the controller signal of the access door 2 is provided on the blocking plate 8. When the anti-falling bolt 5 is plugged into the target plug hole, the sensor 10 is triggered to generate a door opening signal, and the door opening signal is provided to the controller of the access door 2 to trigger the controller of the access door 2 to unlock the access door 2. In this way, it can be ensured that the access door 2 can be opened only after the anti-falling bolt 5 is plugged into the target plug hole. It is prevented that the access door 2 is opened without the anti-falling bolt 5 inserted, causing a safety accident.

[0052] The sensor 10 can be a proximity switch or a photoelectric switch. After the anti-falling bolt 5 is inserted into place, since the distance between the blocking plate 8 and the anti-falling bolt 5 is less than a predetermined value, the proximity switch is triggered by the blocking plate 8 to generate a door opening signal, or the light beam of the photoelectric switch is blocked or reflected by the blocking plate 8, so that the photoelectric switch is triggered to generate a door opening signal.

[0053] Optionally, for convenience, a plurality of plug holes 7 arranged in the vertical direction are provided on the rack 1, such as Figures 4 to 5 As shown, optionally, a plug board 9 extending in the vertical direction is provided on the rack 1, and a plurality of plug holes 7 are equidistantly arranged on the plug board 9 in the vertical direction.

[0054] Optionally, the lifting drive mechanism 3 includes a brake motor 31, a screw 32 and a screw nut, wherein: the brake motor 31 is arranged on the frame 1, one end of the screw 32 is connected to the driving end of the brake motor 31, the other end of the screw 32 is rotatably connected to the frame 1, and the screw nut is screwed on the screw 32 and fixed on the conveying mechanism 4. When the brake motor 31 drives the screw 32 to rotate, the conveying mechanism 4 is stably lifted and lowered through the screw nut. When the brake motor 31 is used as the driving part, when the conveying mechanism 4 accidentally falls, the brake motor 31 can realize the brake, thereby further reducing the risk of the conveying mechanism 4 falling.

[0055] The embodiment of the present application also provides a basket conveying device, which includes a full basket buffer conveyor line, an empty basket buffer conveyor line, an AGV trolley, and an anti-fall basket lifting mechanism provided by any of the above embodiments, wherein: the full basket buffer conveyor line and the empty basket buffer conveyor line are arranged in layers up and down. The anti-fall basket lifting mechanism is located at the back of the full basket buffer conveyor line and the empty basket buffer conveyor line, and the AGV trolley is located at the back of the anti-fall basket lifting mechanism. The lifting drive mechanism is configured to drive the conveying mechanism to lift and lower so that the conveying mechanism docks with the full basket buffer conveyor line or the empty basket buffer conveyor line. Among them, when the conveying mechanism docks with the full basket buffer conveyor line, the conveying mechanism receives the full basket conveyed by the full basket buffer conveyor line and conveys the full basket to the AGV trolley. When the conveying mechanism docks with the empty basket buffer conveyor line, the conveying mechanism transports the empty basket received from the AGV trolley to the empty basket buffer conveyor line.

[0056] It can be seen that through the cooperation of the full basket cache conveyor line, the empty basket cache conveyor line, the AGV trolley and the anti-fall basket lifting mechanism, the basket conveying device in the embodiment of the present application realizes the exchange of baskets between the AGV trolley and the full basket cache conveyor line and the empty basket cache conveyor line.

[0057] In order to achieve the docking between the conveying mechanism 4 and the AGV car, Figure 2 and Figure 4 As shown, optionally, the falling material basket lifting mechanism also includes a transition conveying mechanism 11 arranged on the frame 1, and the transition conveying mechanism 11 is located between the conveying mechanism 4 and the AGV trolley.

[0058] The transition conveying mechanism 11 is used to connect the conveying mechanism 4 and the AGV trolley, so that the conveying mechanism 4 can convey the full basket to the AGV trolley and receive the empty basket sent back by the AGV trolley.

[0059] The present application is described in sufficient detail above with certain particularity. It should be understood by those skilled in the art that the description in the embodiments is merely exemplary, and all changes made without departing from the true spirit and scope of the present application should fall within the scope of protection of the present application. The scope of protection claimed in the present application is defined by the claims, rather than by the above description in the embodiments.
