Description

Technical Field

[0001] This invention relates to the field of automated transmission equipment, and more specifically, to a basket-falling limiter. Background Technology

[0002] Currently, battery cell factories commonly use AGV (Automated Guided Vehicle) handling robots to automate the handling of tooling fixtures, thereby saving manpower and improving efficiency. Among them, AGV handling robots can automatically load and unload baskets containing battery cells and move them to multi-layer racks with slide rails. The multi-layer racks can be distributed with multiple storage spaces from top to bottom for stacking baskets in layers.

[0003] However, with the increase in automation, problems caused by signal connection issues or mechanical reasons have begun to occur frequently.

[0004] However, slowing down the basket's transport speed reduces the amount of battery cells stored in the basket. If the basket's transport speed is increased, and the basket contains a large number of battery cells with significant inertia, the basket may tip over on the AGV or transport conveyor belt, causing damage to the battery cells and increasing the cost of battery cell transport. To address this issue, we propose an anti-tipping basket limiter. Summary of the Invention

[0005] Technical problems to be solved

[0006] To address the problems existing in the prior art, the purpose of this invention is to provide an anti-tipping basket limiter, which can conveniently reduce the damage to battery cells caused by the flower basket tipping over, reduce the transmission cost of battery cells, and allow the spacing of the anti-tipping basket limiter to be adjusted according to the size of the flower basket to adapt to various sizes of flower baskets.

[0007] Technical solution

[0008] To solve the above problems, the present invention adopts the following technical solution.

[0009] Anti-tipping basket limiter, including multi-tier racks and a controller mounted on the multi-tier rack.

[0010] Storage chambers, multiple storage chambers are arranged in a vertical array inside a multi-layer rack, with a feed inlet on one side of each storage chamber and a support mechanism on the other side;

[0011] The two transmission tracks are installed horizontally on both sides of the storage cavity. Each of the two transmission tracks consists of a horizontal plate and a vertical plate installed on the upper edge of the horizontal plate.

[0012] A steel plate is horizontally arranged on the upper surface of a vertical plate near the support mechanism. An elastic strip is provided on the side of the steel plate near the feed inlet. Corner guards are provided on the two edges of the steel plate near the feed inlet. A springback mechanism and a pressure sensor connected to the springback mechanism are provided on the lower surface of the steel plate.

[0013] U-shaped holes, two of which are symmetrically arranged on the upper surface of the steel plate;

[0014] Two fixing screws are respectively inserted into the U-shaped hole, and the lower ends of the fixing screws extend out of the U-shaped hole and are connected to the upper surface of the corresponding vertical plate.

[0015] A limiter consisting of two steel plates can be used to straighten the flower basket in the forward direction, counteract the inertia of the flower basket, reduce the damage to the battery cells caused by the flower basket tipping over, and lower the transmission cost of the battery cells.

[0016] Furthermore, sliders are slidably installed on both sides of the U-shaped hole, and an internally threaded tube is welded between the outer sides of two adjacent sliders. The inner side of the internally threaded tube is threaded to the outer side of the corresponding fixing screw. By having the thread of the internally threaded tube fit into the thread of the fixing screw, the contact area between the steel plate and the corresponding fixing screw can be increased, and the threads on the fixing screw that are crushed can be reduced.

[0017] Furthermore, the rebound mechanism includes a slide cylinder welded to the lower surface of the steel plate. A slide rod is inserted horizontally into the interior of each slide cylinder, with both ends of the slide rod extending out of the slide cylinder. A rubber block is adhered to the end of each slide rod near the corresponding pressure sensor. A spring a, adhered to one side of the rubber block, is sleeved on the outer side of each slide rod. After the basket is removed, the elastic potential energy of the spring a causes the slide rod and rubber block to rebound to their initial position, disengaging from the pressure sensor.

[0018] Furthermore, the support mechanism includes a horizontal brace welded to the other side of the storage cavity in a horizontal direction. The lower surface of the horizontal brace is provided with a tensioning mechanism, and the upper surface of the horizontal brace is welded with an "X"-shaped diagonal brace. The two sides of the diagonal brace are respectively welded to the two sides of the multi-layer frame. The side of the diagonal brace near the feed inlet is bonded with a cubic air bladder. Together with the air bladder 15, they form an elastic support structure that can press against the middle of one side of the flower basket and form three fulcrums with the corresponding two steel plates 4, which can more stably support the flower basket.

[0019] Furthermore, the tensioning mechanism includes a brake motor mounted horizontally on the lower surface of the cross brace. The output end of the brake motor is provided with a metal hook parallel to the transmission track. The metal hook consists of a straight rod and a hook end mounted on one end of the straight rod.

[0020] Beneficial effects

[0021] Compared with the prior art, the advantages of this invention are:

[0022] (1) This solution uses an AGV transport robot to move the flower basket into the designated storage cavity. It slides between two transport tracks until it comes into contact with the steel plate and support mechanism. The two steel plates can form a limiter for the flower basket, which can straighten the flower basket in the forward direction and counteract the inertia of the flower basket. This can reduce the damage to the battery cells caused by the flower basket tipping over and reduce the transport cost of the battery cells. At the same time, the fixing screws can be loosened and the two steel plates can be moved along the U-shaped hole. The spacing of the anti-tipping limiter can also be adjusted according to the size of the flower basket to adapt to the flower basket of various sizes. Then the corresponding steel plate is locked. The corresponding elastic strip and corner protector can form a buffer layer. When in contact with the flower basket, the buffer is carried out by its own deformation, which reduces the hard collision between the flower basket and the steel plate and reduces the degree of deformation of the flower basket caused by the collision.

[0023] (2) When the steel plate is pressed against the basket, the steel plate drives the internal thread tube to squeeze the fixing screw in the horizontal direction. The threads of the internal thread tube fit into the threads of the fixing screw, which can increase the contact area between the steel plate and the corresponding fixing screw and reduce the threads on the fixing screw that are crushed. When the steel plate is moved horizontally, the slide groove can slide relative to the slider, which will not wear the threads on the corresponding fixing screw.

[0024] (3) When the flower basket is moved in this scheme, the flower basket first pushes the slide rod to slide horizontally along the slide cylinder and stretches the spring a until it drives the rubber block to squeeze the detection end of the pressure sensor, so that the pressure sensor detects the pressure signal. The rubber block buffers the pressure sensor through its own deformation to prevent excessive compression of the pressure sensor. After the flower basket is moved away, under the action of the elastic potential energy of the spring a, the slide rod and the rubber block are driven to bounce back to the initial position and disengage from the pressure sensor.

[0025] (4) When the flower basket is removed, the controller starts the brake motor and rotates the metal hook forward. The metal hook approaches the flower basket from below until the hook end is close to the lower surface of the flower basket. Under the action of friction, the flower basket is tightened in the horizontal direction to reduce the degree of shaking of the flower basket. Conversely, the metal hook is rotated in reverse to remove the flower basket and release the tightened state of the flower basket. Attached Figure Description

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0037] Example:

[0038] Please see Figure 1-7 The anti-tipping basket limiter includes a multi-layer rack 1 and a controller mounted on the multi-layer rack 1 by screws.

[0039] Storage chamber 2, multiple storage chambers 2 are arranged in a vertical array inside the multi-layer frame 1, and a feed inlet is provided on one side of the storage chamber 2 and a support mechanism is provided on the other side;

[0040] The two transmission tracks 3 are installed horizontally on both sides of the storage cavity 2. Each of the two transmission tracks 3 consists of a horizontal plate and a vertical plate installed on the upper edge of the horizontal plate. One side of the horizontal plate is fixedly connected to one side of the storage cavity 2 by bolts.

[0041] Steel plate 4 is horizontally positioned on the upper surface of the vertical plate near the support mechanism. Elastic strips 401, made of rubber, are glued to the side of steel plate 4 closest to the feed inlet. Corner guards 402, made of plastic, are glued to the two edges of steel plate 4 closest to the feed inlet. A rebound mechanism and pressure sensors 403 connected to the rebound mechanism are mounted on the lower surface of steel plate 4. The pressure sensors 403 are electrically connected to the controller, which also has a wireless communication module electrically installed. This technical solution is existing technology and is not shown in the figure. The detection ends of the pressure sensors 403 all face the feed inlet.

[0042] U-shaped holes 5, two U-shaped holes 5 are symmetrically arranged on the upper surface of steel plate 4;

[0043] Two fixing screws 6 are respectively inserted into the U-shaped hole 5. The lower end of each fixing screw 6 extends out of the U-shaped hole 5 and is connected to the upper surface of the corresponding vertical plate by thread.

[0044] In operation, the battery cells are stacked in a basket, which is then transported by the conveyor belt of an AGV (Automated Guided Vehicle) robot. The basket is fed into the designated storage cavity 2 through the inlet. The basket slides between two transport tracks 3, contacting and pressing against the rebound mechanism until it presses against the steel plate 4 and the support mechanism. The two steel plates 4 form a limiter for the basket, straightening it in the forward direction and counteracting its inertia. This reduces the risk of damage to the battery cells caused by the basket tipping over, lowering the transport cost. Simultaneously, the fixing screws 6 can be loosened, allowing the two steel plates 4 to move along the U-shaped hole 5. The anti-tipping mechanism can also be adjusted according to the size of the basket. The spacing of the basket limiters is adjusted to fit various sizes of flower baskets. Then, the fixing screws 6 are tightened, and the corresponding steel plate 4 is locked under friction. The corresponding elastic strips 401 and corner protectors 402 can form a buffer layer, which buffers the flower basket by its own deformation when in contact with the flower basket, reducing the hard collision between the flower basket and the steel plate 4 and reducing the degree of deformation caused by the collision. Then, the rebound mechanism squeezes the detection end of the pressure sensor 403. After the pressure sensor 403 detects the pressure signal, it converts it into an electrical signal and transmits it to the controller. The controller sends the unloading instruction to the AGV handling robot through the wireless communication module, and the flower basket is unloaded.

[0045] See Figure 1 and Figure 3Both sides of the U-shaped hole 5 are equipped with sliders 7 via sliding grooves. An internally threaded tube 8 is welded between the outer sides of two adjacent sliders 7. The inner side of the internally threaded tube 8 is threaded to the outer side of the corresponding fixing screw 6. When the present invention is pressed against the basket, the steel plate 4 drives the internally threaded tube 8 to press the fixing screw 6 in the horizontal direction. By the thread of the internally threaded tube 8 adhering to the thread of the fixing screw 6, the contact area between the steel plate 4 and the corresponding fixing screw 6 can be increased, reducing the threads on the fixing screw 6 that are crushed. The steel plate 4 can slide relative to the slider 7 via the sliding groove, without wearing the threads on the corresponding fixing screw 6.

[0046] See Figure 1 , Figure 3 and Figure 6 The rebound mechanism includes a slide cylinder 9 welded to the lower surface of the steel plate 4. Slide rods 10 are horizontally inserted into the interior of each slide cylinder 9, with both ends of the slide rods 10 extending out of the slide cylinder 9. A rubber block 12 is adhered to the end of each slide rod 10 closest to the corresponding pressure sensor 403. A spring a11, adhered to one side of the rubber block 12, is sleeved on the outer side of each slide rod 10. When the flower basket is moved, the flower basket first pushes the slide rod 10, which slides horizontally along the slide cylinder 9 and stretches the spring a11 until the rubber block 12 presses against the detection end of the pressure sensor 403, causing the pressure sensor 403 to detect a pressure signal. The rubber block 12 buffers the pressure sensor 403 through its own deformation, preventing excessive pressure. After the flower basket is moved, the elastic potential energy of the spring a11 causes the slide rod 10 and rubber block 12 to rebound to their initial positions, disengaging from the pressure sensor 403.

[0047] See Figure 2 and Figure 5 The support mechanism includes a horizontal brace 13 welded to the other side of the storage cavity 2 along the horizontal direction. The lower surface of the horizontal brace 13 is provided with a tensioning mechanism. The upper surface of the horizontal brace 13 is welded with an X-shaped diagonal brace 14. The two sides of the diagonal brace 14 are respectively welded to the two sides of the multi-layer frame 1. The side of the diagonal brace 14 near the feed inlet is bonded with a cubic airbag 15. When supporting the flower basket, the other side of the storage cavity 2 is sealed with the horizontal brace 13 and the corresponding diagonal brace 14. Together with the airbag 15, they form an elastic support structure that can press against the middle of one side of the flower basket and form three fulcrums with the two corresponding steel plates 4, which can more stably support the flower basket.

[0048] See Figure 1 and Figure 3On the side of the diagonal brace 14 away from the feed inlet, a timer switch 16 and an LED light 17 electrically connected to the timer switch 16 are fixedly installed by screws. When the pressure sensor 403 of the present invention is working, the controller controls the timer switch 16 to open, so that the LED light 17 is powered on and emits a red light within a specified time period to indicate the working status. Then, it emits a green light within a specified time period to indicate the status of carrying the flower basket. Finally, the LED light 17 is turned off.

[0049] See Figure 1 , Figure 2 and Figure 5 The lower surface of the airbag 15 is provided with multiple telescopic rods 18 arranged in a horizontal array. One end of each telescopic rod 18 is connected to one side of the corresponding diagonal brace 14. The other ends of each telescopic rod 18 are connected to a perforated plate 19 in a vertical direction. The side of the perforated plate 19 away from the feed inlet is connected to one side of the corresponding airbag 15. When the airbag 15 is working, it is supported from below by multiple telescopic rods 18, which makes it easy for the airbag 15 to be suspended in the air. The perforated plate 19 blocks one side of the airbag 15, which makes it easy for the airbag 15 to contact the flower basket with the perforated plate 19. The telescopic rods 18 extend and retract with the displacement of the perforated plate 19, which can limit the direction of the perforated plate 19.

[0050] See Figure 1 , Figure 3 and Figure 4 The tensioning mechanism includes a brake motor 20 bolted to the lower surface of the cross brace 13 in a horizontal direction. The output end of the brake motor 20 is provided with a metal hook 21 parallel to the transmission track 3. The metal hook 21 consists of a straight rod and a hook end installed at one end of the straight rod. When the flower basket is removed, the controller starts the brake motor 20 to rotate the metal hook 21 in the forward direction. The metal hook 21 approaches the flower basket from below until the hook end is close to the lower surface of the flower basket. Under the action of friction, the flower basket is tightened in the horizontal direction, reducing the degree of shaking of the flower basket. Conversely, the metal hook 21 is rotated in the reverse direction to disengage from the flower basket, thereby releasing the tension of the flower basket.

[0051] See Figure 3 and Figure 7 Each end of the hook away from the straight rod is provided with a sleeve 22. Each sleeve 22 has an open end. A spring b23 is welded and installed between the inner side of the sleeve 22 and the corresponding end of the hook. When the metal hook 21 of this invention presses against the flower basket, it drives the sleeve 22 to contact the flower basket. As the metal hook 21 rotates, the sleeve 22 slides along the hook end and squeezes the spring b23 to buffer and avoid hard collision with the flower basket.

[0052] See Figure 3 and Figure 7The sleeve 22 is attached to a frosted sheet 24 at the end away from the metal hook 21. The outer side of the frosted sheet 24 has rounded corners. When the sleeve 22 of the present invention is pressed against the flower basket, it drives the frosted sheet 24 to press against the lower surface of the flower basket, which can enhance the friction between the sleeve 22 and the lower surface of the flower basket and reduce the degree of relative sliding between the flower basket and the sleeve 22.

[0053] See Figure 1 , Figure 4 and Figure 7 A flange ring 25 is fixedly installed between one end of the straight rod and the output end of the corresponding brake motor 20. One side of the flange ring 25 is welded to one end of the corresponding straight rod, and the inner side of the flange ring 25 is fixedly connected to the output end of the corresponding brake motor 20 by bolts. Reinforcing ribs 26 are welded to both sides of the straight rod. When the invention is working, the flange ring 25 is used to increase the connection area between one end of the straight rod and the output end of the corresponding brake motor 20 to enhance the support strength of the connection. The two reinforcing ribs 26 are used to enhance the support strength of the straight rod, so as to facilitate the strength of the metal hook 21 to tighten the flower basket.

[0054] Working Principle: In operation, the battery cells are placed in a basket and transported by the conveyor belt of an AGV transport robot. The basket is fed into the designated storage cavity 2 through the feed inlet. The basket slides between two transport tracks 3. The basket first pushes the slide rod 10, which slides horizontally along the slide cylinder 9 and stretches the spring a11 until it drives the rubber block 12 to squeeze the detection end of the pressure sensor 403. This causes the pressure sensor 403 to detect the pressure signal, and the rubber block 12 buffers the pressure sensor 403 through its own deformation, preventing excessive compression. The basket is then pressed against the steel plate 4 and the support mechanism. The two steel plates 4 can form a limiter for the basket, which straightens the basket in the forward direction and counteracts the inertia of the basket. This reduces the damage to the battery cells caused by the basket tipping over and lowers the transportation cost of the battery cells. Meanwhile, the steel plate 4 drives the internal thread tube 8 to squeeze the fixing screw 6 in the horizontal direction. The threads of the internal thread tube 8 fit into the threads of the fixing screw 6, which increases the contact area between the steel plate 4 and the corresponding fixing screw 6 and reduces the damage to the threads of the fixing screw 6.

[0055] At the same time, the fixing screws 6 can be loosened, and the two steel plates 4 can be moved along the U-shaped hole 5. They can slide relative to the slider 7 using the sliding groove, which will not wear the threads on the corresponding fixing screws 6. The spacing of the anti-tipping limiter can also be adjusted according to the size of the flower basket to fit flower baskets of various sizes. Then, the fixing screws 6 can be tightened to lock the corresponding steel plate 4 under the action of friction. The corresponding elastic strip 401 and corner protector 402 can form a buffer layer, which can buffer the flower basket by its own deformation when in contact with the flower basket, reducing the hard collision between the flower basket and the steel plate 4 and reducing the degree of deformation of the flower basket caused by the collision.

[0056] Then the rebound mechanism squeezes the detection end of the pressure sensor 403. After the pressure sensor 403 detects the pressure signal, it converts it into an electrical signal and transmits it to the controller. The controller sends the unloading instruction to the AGV handling robot through the wireless communication module, and the flower basket is unloaded.

[0057] Then the controller starts the brake motor 20, which rotates the metal hook 21 forward. The metal hook 21 approaches the flower basket from below until the hook end is close to the lower surface of the flower basket. Under the action of friction, the flower basket is tightened in the horizontal direction, reducing the degree of shaking of the flower basket.

[0058] Finally, reverse the metal hook 21 to detach it from the flower basket, thus releasing the tension of the flower basket. After the flower basket is removed, under the action of the elastic potential energy of the spring a11, the slide bar 10 and the rubber block 12 will spring back to their initial positions and detach from the pressure sensor 403.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concepts, should be covered within the scope of protection of the present invention.
