Description

Technical Field

[0001] This utility model relates to the field of material transfer equipment technology, and in particular to a multi-layer transfer cart. Background Technology

[0002] The water-cooled plate of the battery pack in new energy vehicles is a key component of the battery thermal management system. Its main function is to absorb and dissipate the heat generated by the battery during charging and discharging through circulating coolant, ensuring the battery operates within its optimal temperature range (typically 25-40℃), thereby improving efficiency, safety, and lifespan. Water-cooled plates are usually made of lightweight materials such as aluminum alloys and feature a sophisticated internal flow channel structure through which coolant flows for efficient heat exchange. The thickness of a water-cooled plate is typically around 2-5 millimeters, while its area can reach 500 square millimeters, exhibiting a large width-to-thickness ratio, making it a typical thin-walled component.

[0003] After the internal liquid channels of the water-cooled plate are processed and a special coating such as insulating powder coating is sprayed on the surface, it needs to be transferred to other workstations for further processing. Conventional transfer carts can only load materials by stacking them upwards and limiting them on all four sides. This method will cause the water-cooled plates to come into contact with each other. During transportation, the water-cooled plates will move and scratch the surface coating. If partitions are set between the stacked water-cooled plates, it will be inconvenient for the subsequent material handling robot to take the water-cooled plates upwards. Since the water-cooled plates are thin-walled parts and have protruding attachments on their surface, horizontal stacking can easily cause the water-cooled plates to deform. Therefore, conventional transfer carts are not suitable for the transfer of water-cooled plates. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a multi-layer transfer cart to solve the problem that existing transfer carts are prone to material deformation and inconvenient for robots to pick up materials when transferring thin-walled parts such as water-cooled plates.

[0005] To achieve the above objectives, this utility model provides a multi-layer transfer cart, comprising a base, several placement groups arranged on the base along the walking direction for placing water-cooled plates, and traveling wheels arranged at the bottom of the base. Each of the several placement groups includes insertion slots symmetrically arranged on both sides of the base for inserting both ends of the water-cooled plates. The vertical dimension of each insertion slot is adapted to the height of the water-cooled plate, and the distance between the two insertion slots in each placement group is adapted to the lateral dimension of the water-cooled plate. The width of the insertion slots is set so that the water-cooled plates placed in the insertion slots can be adjusted to a vertical state.

[0006] Furthermore, a plurality of first U-shaped frames distributed along the walking direction are provided on one side of the base, and a plurality of second U-shaped frames symmetrically distributed with the plurality of first U-shaped frames are provided on the other side of the base. The openings of the first U-shaped frames and the second U-shaped frames are opposite to each other to form corresponding insertion slots, and each first U-shaped frame and its symmetrical second U-shaped frame form a placement group.

[0007] Furthermore, a first connecting plate is provided on the back of a plurality of the first U-shaped frames, the first connecting plate being used to connect the plurality of the first U-shaped frames into a whole; a second connecting plate is provided on the back of a plurality of the second U-shaped frames, the second connecting plate being used to connect the plurality of the second U-shaped frames into a whole; Both the first U-shaped frame and the second U-shaped frame have connecting blocks at their bottoms, and bolt holes are provided on the connecting blocks. Both the first U-shaped frame and the second U-shaped frame are detachably connected to the base through the connecting blocks.

[0008] Furthermore, each of the insertion slots has a first rubber layer on its wall.

[0009] Furthermore, each placement group also includes a support member disposed on the base and located between two symmetrical insertion slots, each of the support members being used to insert the lower end of the corresponding water-cooled plate into the slot.

[0010] Furthermore, each of the aforementioned support members includes several U-shaped seats spaced apart between two symmetrical insertion slots and opening upwards. The U-shaped seats are detachably connected to the base by bolts, and a second rubber layer is provided on the surface of the U-shaped seats that contacts the water-cooling plate.

[0011] Furthermore, the upper surface of the base is configured as an inclined surface that is tilted upward along the driving direction, and the tilt angle of the inclined surface is 5 to 15 degrees.

[0012] Furthermore, the base includes a base frame and mounting plates laid on both sides of the base frame, the placement group is disposed on the mounting plate, and the upper surface of the mounting plate forms the inclined surface.

[0013] Furthermore, a pusher is provided on the side of the base away from the driving direction, and baffles are provided between the U-shaped frames on both sides of the base near the pusher, with the two ends of the baffles respectively fixedly connected to the corresponding U-shaped frames.

[0014] Furthermore, the base is provided with four wheels at its bottom corners, and the two wheels closest to the pusher are set as omnidirectional wheels with foot brakes; the multi-layer transfer cart also includes a guide mechanism, which is a guide wheel set symmetrically arranged on both sides of the bottom of the base. The guide wheel set includes multiple rollers arranged sequentially along the travel direction. The bottom of the base is provided with a mounting seat corresponding to each roller. The roller is rotatably connected to the mounting seat, and the rotation axis of the roller is vertically arranged.

[0015] The upper surface of the base of the transfer cart of this utility model is inclined. When the water-cooled plate is placed in the insertion slot, the water-cooled plate is also inclined away from the direction of travel. Therefore, the water-cooled plate is not easily deformed and will not sway back and forth during transportation. Adjacent water-cooled plates are isolated and do not contact each other, so they will not rub against each other and scrape off the surface coating. The water-cooled plate can be adjusted to a vertical state in the insertion slot, which makes it easy for the robot to take the water-cooled plate out upwards. The bottom of the transfer cart is equipped with a set of guide wheels, which can cooperate with the guide rail on the ground at the robot picking point to easily guide the transfer cart to the designed parking position.

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0027] This embodiment discloses a multi-layer material transfer cart, such as Figures 1-8 As shown, it includes a base, multiple placement groups 30 disposed on the base for placing water-cooled plates 80, and wheels 20 disposed at the bottom of the base.

[0028] The base includes a base frame 102 made of rectangular tube and mounting plates 101 laid on the upper ends of both sides of the base frame 102. Specifically, the base frame 102 can be formed by welding metal rectangular tubes, and then the metal mounting plates 101 are welded to the surface of the base frame 102 to form the base. The mounting plates 101 on both sides of the base frame 102 are coplanar. The upper surface of the mounting plate 101 is also the upper surface of the base. The upper surface of the base is inclined upward along the driving direction. The inclination angle of the upper surface of the base is 5 to 15 degrees. The inclination angle of the upper surface of the base is defined as the minimum angle between the upper surface of the base and the horizontal plane. In this embodiment, the inclination angle of the upper surface of the base is 10 degrees. In other feasible embodiments, the inclination angle of the upper surface of the base can be set to 5 degrees, 12 degrees, or 15 degrees, etc., depending on the thickness and external dimensions of the water-cooled plate 80.

[0029] The base is equipped with four corners of the bottom of the base, and the wheels 20 are detachably connected to the base frame 102 by screws to facilitate replacement of the wheels 20. The base is provided with a push handle 50 to facilitate the movement of the material cart. The push handle 50 is located on the side of the base away from the direction of travel, that is, on the base frame 102 at the lowest point of the surface of the mounting plate 101. The two wheels 20 near the push handle 50 are set as universal wheels with foot brakes to facilitate stopping the material cart at any time.

[0030] Multiple placement groups 30 are arranged sequentially on the upper surface of the mounting plate 101 along the driving direction. Each placement group 30 includes insertion slots 36 symmetrically arranged on both sides of the base for inserting both ends of the water-cooled plate, and a support member disposed on the base between the two symmetrical insertion slots 36. Each support member is used for inserting the lower end of the corresponding water-cooled plate. The vertical dimension of each insertion slot 36 is adapted to the height of the water-cooled plate, and the distance between the two insertion slots 36 of each placement group 30 is adapted to the lateral dimension of the water-cooled plate. The base has several first U-shaped frames 31 arranged along the walking direction on one lateral side, and several second U-shaped frames 35 symmetrically distributed with respect to the first U-shaped frames 31 on the other lateral side. The openings of the first U-shaped frames 31 and the second U-shaped frames 35 face each other to form corresponding insertion slots 36. Each first U-shaped frame 31 and its symmetrical second U-shaped frame 35 form a placement group 30. Both the first U-shaped frames 31 and the second U-shaped frames 35 are perpendicular to the upper surface of the mounting plate. When the water-cooled plate 80 is placed in the insertion slot... When the water-cooled plate 80 is in the slot 36, it is also tilted away from the direction of travel. The opening width of the first U-shaped frame 31 and the second U-shaped frame 35 can be set according to the tilt angle of the upper surface of the base, the thickness of the water-cooled plate 80 and the outer dimensions of the water-cooled plate 80. It is set so that the water-cooled plate 80 placed in the insertion slot 36 can be adjusted to a vertical state and will not scrape against the inner wall of the insertion slot 36 when it moves upward. This allows the material handling robot to adjust the water-cooled plate 80 to a vertical state and then move it vertically upward to remove the water-cooled plate 80 when picking up the material. In this embodiment, the first U-shaped frame 31 and the second U-shaped frame 35 can be stamped from strip metal sheets. A connecting block 34 is fixedly connected to the bottom of both the first U-shaped frame 31 and the second U-shaped frame 35. The metal connecting block 34 can be welded to the bottom of the first U-shaped frame 31 and the second U-shaped frame 35. Bolt holes are provided on the connecting block 34. The connecting block 34 can be fastened to the mounting plate 101 by bolts to realize the bolted detachable connection between the first U-shaped frame 31 and the second U-shaped frame 35 and the mounting plate 101. A first rubber layer 311 is provided on the inner wall of both the first U-shaped frame 31 and the second U-shaped frame 35 to prevent the water-cooled plate 80 from directly contacting the first U-shaped frame 31 or the second U-shaped frame 35.

[0031] To improve the stability of the entire material transfer vehicle, a first connecting plate 331 is provided on the back of several first U-shaped frames 31, which is used to connect several first U-shaped frames 31 into a whole; a second connecting plate 332 is provided on the back of several second U-shaped frames 35, which is used to connect several second U-shaped frames 35 into a whole. A baffle 60 is horizontally provided between the first U-shaped frames 31 and the corresponding second U-shaped frames 35 on both sides of the base near the pusher 50. The two ends of the baffle 60 are fixedly connected to the first U-shaped frame 31 and the corresponding second U-shaped frame 35, respectively. The setting of the connecting plate 331 and the baffle 60 improves the integrity between the first U-shaped frames 31 and the second U-shaped frames 35 on both sides of the base and enhances the stability.

[0032] Each of the aforementioned support members includes several U-shaped seats 32 spaced apart between two symmetrical insertion slots 36 and opening upwards. The U-shaped seats 32 are detachably connected to the base by bolts, and a second rubber layer is provided on the surface of the U-shaped seats 32 that contacts the water-cooled plate 80.

[0033] A guide mechanism is provided at the bottom of the base. The guide mechanism consists of guide wheel sets symmetrically arranged on both sides of the bottom of the base. Each guide wheel set includes multiple rollers 41 arranged sequentially along the travel direction. A mounting base 42 is provided at the bottom of the base to cooperate with the rollers 41. The mounting base 42 is detachably connected to the base by bolts. The rollers 41 are rotatably connected to the mounting base 42. The rotation axis of the rollers 41 is vertically arranged. At the end point of the water-cooled plate 80 transfer, a guide rail 70 is provided on the ground to cooperate with the two guide wheel sets respectively. When the rollers 41 are connected to the guide rails 70, the rollers 41 roll forward along the outer wall of the guide rails 70, which can easily push the material cart to move along the guide rails 70 in the set direction to the designated location.

[0034] The upper surface of the base of the transfer cart of this utility model is inclined. When the water-cooled plate 80 is placed in the insertion slot 36, the water-cooled plate 80 is also inclined away from the direction of travel. Therefore, the water-cooled plate 80 is not easily deformed and will not sway back and forth during transportation. Adjacent water-cooled plates 80 are isolated and do not contact each other, so they will not rub against each other and scrape off the surface coating. The water-cooled plate 80 can be adjusted to a vertical state in the insertion slot 36, which makes it convenient for the robot to take out the water-cooled plate 80 upwards. The bottom of the transfer cart is equipped with a guide wheel set, which can cooperate with the guide rail 70 on the ground at the robot picking point to easily guide the transfer cart to the designed parking position, so as to facilitate the picking robot to pick up the water-cooled plate 80 in sequence.

[0035] The above embodiments only illustrate preferred implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
