Description

Technical Field

[0001] This utility model relates to the field of automotive parts transfer technology, and more specifically, to an automotive side panel parts trolley. Background Technology

[0002] Automotive body side panel parts are core large-scale covering components forming the passenger compartment skeleton. They are characterized by large size, complex shape, low rigidity (mostly made of high-strength steel or aluminum alloy sheet stamping), and high surface quality requirements. Therefore, specialized trolleys are needed to place, store, and transport these parts, preventing deformation or surface wear due to collisions or improper placement during daily production, storage, and transportation, which could lead to defective parts. Current technology typically uses multiple support rods within the trolley to hold the side panel parts. These rods constrain the parts, and an excessive number of constraints significantly increases the difficulty of automated part handling, making it challenging to remove and place side panel parts. This is especially problematic given the current trend towards automation in automotive manufacturing; excessive constraints hinder robotic arm operation, making automated removal and placement difficult and failing to meet the demands of this automation transformation. Meanwhile, existing trolleys generally need to be designed according to the shape of the side panel parts. Different car models have different shapes of side panel parts, and existing trolleys generally need to be specially designed for the shape of the side panel. Each trolley can only be used to transport a single type of side panel part, lacking versatility and unable to be adjusted according to different external shapes of the side panel, which greatly increases the design and manufacturing cost of trolleys for car side panel parts. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a trolley for automotive side panel parts, which can store and collect side panels while facilitating handling by robotic arms. It is suitable for automated production scenarios and can be adjusted to adapt to side panel parts of different specifications.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a trolley for automotive side panel parts, including a base plate, uprights vertically arranged at the four corners of the base plate, a first side plate arranged between the uprights on the front and rear sides of the same side of the base plate, a second side plate arranged between the two uprights on the front side and the two uprights on the rear side of the base plate, at least two horizontally arranged upper supports arranged on the first side plate, a lower support arranged horizontally on the base plate, a slotted component arranged on the upper surface of both the upper and lower supports, a plurality of slots arranged along the length direction on the slotted component, and an adjustable height adjustment device arranged on the lower support.

[0005] In this technical solution, the base plate is the basic structure of the automotive side panel parts trolley. Columns at the four corners of the base plate are used to install and support the first and second side panels. The first, second, and base plates together form a receiving space for accommodating the side panel parts. Only one first side panel is provided, making one side of the receiving space an open surface, allowing workers or machinery to insert or remove automotive side panel parts through this open surface. At least two upper supports are provided on the first side panel, both being horizontally arranged rod-like structures. Automotive side panel parts generally have A-pillars, B-pillars, C-pillars, and a top longitudinal beam. The A-pillars, B-pillars, C-pillars, and the top longitudinal beam together form at least two door frames. The two upper supports are inserted into the two door frames respectively, and the automotive top longitudinal beam is placed on the two upper supports, thus hanging the side panel parts on the two upper supports. Multiple automotive side panel parts can be hung on the upper supports along their length. During actual transport, the trolley inevitably sways, and due to its own inertia, the side panel parts slide on the upper support, causing different side panel parts to collide. Therefore, a structure is needed on the upper support to limit the sliding of the side panel parts. The upper support has multiple slots on its locking mechanism, each corresponding to a single side panel part. The top crossbeam of the side panel part can be locked into the slot, and under its own weight, the side panel part cannot move upward and slide out of the slot. Since the upper support extends from the first side plate and is suspended in the air, it is prone to bending under excessive weight. Therefore, a lower support is also provided on the base plate. The lower support can support the side panel parts from below, distributing the weight of the side panel parts and preventing the upper support from bearing the entire weight of the side panel parts. Meanwhile, the slots on the upper bracket only restrict the upper part of the side panel parts, leaving the lower part unrestricted and prone to collision due to swaying. Therefore, a slot with multiple slots is also needed on the lower bracket, where the lower part of the side panel parts are engaged to secure the lower part of the car side panel. Thus, the two upper and lower brackets provide only three fixing points for the side panel parts, ensuring complete fixation while minimizing fixing points for easy gripping and placement, facilitating automated gripping and placement. The upper structure is largely the same for different types of car side panels, so the upper bracket can accommodate most side panel parts. However, from the perspective of fixing side panel parts, the main difference between side panel parts of different car models lies in their vertical height. Therefore, an adjustable height device is also provided on the lower bracket to accommodate side panel parts of different heights.

[0006] Preferably, the adjusting device includes a guide cylinder, a guide rod, and a fastener. The guide cylinder is vertically installed on the upper surface of the base plate, and the upper end of the guide cylinder is open. The upper end of the guide rod is fixed to the lower surface of the lower bracket, and the lower end of the guide rod is inserted into the guide cylinder. The guide cylinder is provided with a threaded hole, and the outer peripheral surface of the fastener is provided with threads. The fastener is threadedly connected to the threaded hole and inserted into the guide cylinder to abut against the outer wall surface of the guide rod.

[0007] Preferably, multiple threaded holes are provided, the multiple threaded holes are at the same height, the multiple threaded holes are arranged circumferentially along the guide cylinder, and the number of fasteners matches the number of threaded holes.

[0008] Preferably, the slot is made of polyurethane material.

[0009] Preferably, the bottom surface of the base plate is also provided with positioning holes.

[0010] Preferably, at least two positioning holes are provided, and the two positioning holes are symmetrically arranged with the center of the bottom surface of the base plate as the center of symmetry.

[0011] Preferably, an adhesive plate for attaching a QR code is provided at the center between the two positioning holes, and a cross line is engraved on the bottom surface of the adhesive plate.

[0012] Preferably, the base plate includes an upper base plate and a lower base plate, the upper base plate and the lower base plate are connected by a structural rod, an overhead space is formed between the upper base plate and the lower base plate, and the side of the base plate is also provided with an insertion hole for a forklift to be inserted into the overhead space.

[0013] Preferably, the upper end of the column is higher than the first side plate and the second side plate, and the lower end of the column is provided with a foot cup, which is disposed inside the base plate. The bottom surface of the base plate has a channel for inserting the foot cup.

[0014] Preferably, the base plate is also provided with RFID sticky notes.

[0015] Compared with existing technologies, the advantages of this technical solution are as follows: Two upper supports and one lower support are provided, achieving three-point fixation for the side panel parts. This ensures the stability of the side panel parts while minimizing the number of fixed points, facilitating handling and placement, and making it suitable for robotic arm handling. Positioning grooves and locking slots are provided on the upper and lower supports to limit the position of the side panel parts and prevent shaking or collisions that could damage them. The lower support is also equipped with an adjustable height device, allowing it to be adjusted to accommodate different types of side panel parts. Attached Figure Description

Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0020] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings: Example 1 like Figure 1As shown, a car side panel parts trolley includes a base plate 1, with uprights 2 vertically arranged at the four corners of the base plate 1. A first side plate 3 is arranged between the uprights 2 on the front and rear sides of the same side of the base plate 1. A second side plate 4 is arranged between the two uprights 2 on the front side and the two uprights 2 on the rear side of the base plate 1, respectively. At least two horizontally arranged upper supports 5 are arranged on the first side plate 3. A lower support 6 is horizontally arranged on the base plate 1. The upper surfaces of the upper supports 5 and the lower support 6 are provided with slots 8. Multiple slots are arranged along the length direction on the slots 8. An adjustable height adjustment device 7 is provided on the lower support 6. The base plate 1 is the basic structure of the automotive side panel parts trolley. The uprights 2 at the four corners of the base plate 1 are used to install and support the first side plate 3 and the second side plate 4. The first side plate 3, the second side plate 4, and the base plate 1 together form a receiving space for accommodating the side panel parts. Only one first side plate 3 is provided, making one side of the receiving space an open surface, allowing workers or machinery to insert or remove automotive side panel parts through this open surface. At least two upper supports 5 are provided on the first side plate 3, both of which are horizontally arranged rod-like structures. Automotive side panel parts generally have A-pillars, B-pillars, C-pillars, and a top longitudinal beam. The A-pillars, B-pillars, C-pillars, and the top longitudinal beam together form at least two door frames. The two upper supports 5 are inserted into the two door frames respectively, and the automotive top longitudinal beam is placed on the two upper supports 5, thus hanging the side panel parts on the two upper supports 5. Multiple automotive side panel parts can be hung on the upper supports 5 along their length. During actual transport, the trolley inevitably sways, and due to its own inertia, the side panel parts slide on the upper support 5, causing different side panel parts to collide. Therefore, a structure is needed on the upper support 5 to limit the sliding of the side panel parts. The upper support 5 is equipped with a locking member 8, which has multiple locking slots. Each locking slot corresponds to a single side panel part. The top crossbeam on the side panel part can be locked into the locking slot. Under the constraint of its own weight, the side panel part cannot move upward and thus cannot slide out of the locking slot. Since the upper support 5 extends from the first side plate 3 and is in a suspended state, it is prone to bending if it bears too much weight. Therefore, a lower support 6 is also provided on the base plate 1. The lower support 6 can support the side panel parts from below, distributing the weight of the side panel parts and preventing the upper support 5 from bearing the entire weight of the side panel parts. Meanwhile, the positioning grooves on the side panel parts only restrict the upper part of the side panel parts, while the lower part of the side panel parts lacks restriction and is prone to collision due to shaking. Therefore, it is necessary to also set a slotting component 8 with multiple slots on the lower bracket 6. The lower part of the side panel parts is inserted into the slots to fix the lower part of the car side panel. Thus, the two upper brackets 5 and the lower bracket 6 only provide three fixing points for the side panel parts. While ensuring that the side panel parts can be completely fixed, having as few fixing points as possible makes it easy to grasp and place, facilitating automated grasping and placement.When retrieving side panel parts from the trolley, the robotic arm simply extends into the receiving space to grasp the part, then slightly lifts it to remove it from the positioning slot and retaining groove. The robotic arm can then directly grasp the part and move it laterally. The process of placing side panel parts is similar. The retaining groove 8 is prone to wear over time due to its contact with the side panel parts. The retaining groove 8 is detachably connected to the upper bracket 5 and lower bracket 6, making it easy to replace after wear. The upper structure of different types of car side panels is generally similar; therefore, the upper bracket 5 can accommodate most side panel parts. From the perspective of fixing the side panel parts, the main difference between side panel parts of different car models lies in their vertical height. Therefore, the lower bracket 6 is equipped with an adjustable height adjustment device 7, allowing it to accommodate side panel parts of different heights by adjusting the height of the lower bracket 6.

[0021] like Figure 3 As shown, the adjusting device 7 includes a guide cylinder 71, a guide rod 72, and a fastener 73. The guide cylinder 71 is vertically mounted on the upper surface of the base plate 1, with its upper end open. The upper end of the guide rod 72 is fixed to the lower surface of the lower support 6, and the lower end of the guide rod 72 is inserted into the guide cylinder 71. The guide cylinder 71 has a threaded hole, and the outer circumferential surface of the fastener 73 is threaded. The fastener 73 is threadedly connected to the threaded hole and inserted into the guide cylinder 71, abutting against the outer wall surface of the guide rod 72. The lower support 6 is fixed to the base plate 1 by the guide cylinder 71 and the guide rod 72. The guide rod 72 is inserted into the guide cylinder 71 to different depths, thus allowing the adjusting device 7 to have different heights, thereby adjusting the height of the lower support 6 located on the adjusting device 7. The fastener 73 is threadedly connected to the threaded hole on the guide cylinder 71. The operator can tighten the fastener 73 to insert it into the guide cylinder 71 and abut against the outer wall surface of the guide rod 72 located inside the guide cylinder 71, thereby fixing the position of the guide rod 72. Since the fastener 73 can be fixed by abutting against any point on the outer wall of the guide rod 72, the adjustment device 7 can be steplessly adjusted within the movable range of the guide rod 72 inserted into the guide cylinder 71, and can be adapted to side wall parts of various heights.

[0022] like Figure 3 As shown, multiple threaded holes are provided, all at the same height, and arranged circumferentially along the guide cylinder 71. The number of fasteners 73 matches the number of threaded holes. By providing multiple fasteners 73 to abut against the guide rod 72, the number of fixing points for the guide rod 72 is increased, making the guide rod 72 more securely fixed. The fact that multiple threaded holes are at the same height ensures that all fasteners 73 can abut against the guide rod 72 within the adjustment range, preventing a situation where only some fasteners 73 can abut against the guide rod 72, thus preventing a reduction in the tightening capacity of the guide rod 72.

[0023] like Figure 1As shown, the slot component 8 is made of polyurethane. Polyurethane material offers high processing precision, good durability, and will not damage parts, making it suitable for direct contact with side panel components.

[0024] Example 2 This embodiment is similar to Embodiment 1 above, except that, as Figure 2 As shown, the bottom surface of the base plate 1 is also provided with positioning holes 9. The trolley is transported by an AGV robot, which is equipped with positioning pins. The positioning pins can be inserted into the positioning holes 9 to determine the position of the trolley on the AGV robot. At the same time, the positioning holes 9 can also be used for trolley positioning during the automatic packing process of APS parts.

[0025] like Figure 2 As shown, at least two positioning holes 9 are provided, symmetrically arranged around the center of the bottom surface of the base plate 1. By providing at least two positioning holes 9, the trolley's position can be completely fixed by interlocking with two positioning pins located on the AGV robot. The two positioning pins on the AGV robot are a round pin and a diamond pin, respectively. To ensure stable support of the trolley by the AGV robot during handling, the AGV robot typically supports the trolley at the center of the bottom surface of the base plate 1. The two positioning holes 9 also need to be symmetrically arranged around the center of the bottom surface of the base plate 1 to ensure stable fixation of the trolley in all directions. The two positioning holes 9 can also be used to position the trolley by inserting two positioning pins provided at the APS automatic packing station.

[0026] like Figure 2 As shown, an adhesive plate 14 for attaching QR codes is also provided at the center between the two positioning holes 9. Cross lines are engraved on the bottom surface of the adhesive plate 14. By attaching QR codes to the adhesive plate 14, the AGV robot can recognize them for precise positioning and to obtain information about the trolley parts to facilitate route planning. The cross lines engraved on the bottom surface of the adhesive plate 14 help determine the placement of the QR codes, ensuring the accuracy of the attachment.

[0027] Example 3 This embodiment is similar to Embodiment 1 above, except that, as Figure 1 As shown, the base plate 1 includes an upper base plate 11 and a lower base plate 12, which are connected by structural rods. An open space is formed between the upper base plate 11 and the lower base plate 12. The side of the base plate 1 is also provided with insertion holes 13 for forklifts to insert into the open space. Inserting a forklift into the insertion holes 13 ensures that the trolley will not fall off during transport, thus guaranteeing safety during handling.

[0028] like Figure 1 , 4As shown, the upper end of the column 2 is higher than the first side plate and the second side plate, and the lower end of the column 2 is provided with a foot cup 21. The foot cup 21 is set inside the base plate 1, and the bottom surface of the base plate 1 has a channel for inserting the foot cup 21. Multiple trolleys can be stacked for storage. By setting the upper end of the column 2 to be higher than the first side plate 3 and the second side plate 4, the weight of the trolleys when stacked vertically will be entirely borne by the column 2, resulting in a better load-bearing structure. The lower end of the column 2 is provided with a foot cup 21, which has a larger contact area and abuts against the column 2 located on the trolley below. The foot cup 21 is set inside the base plate 1, forming a semi-concealed structure, which avoids collisions during transportation caused by the foot cup 21 protruding from the surface of the base plate 1.

[0029] like Figure 1 As shown, RFID tags are also installed on the base plate 1. RFID tags are an automatic identification technology based on radio frequency communication, which enables contactless data reading and writing and target tracking through radio waves. By setting RFID tags, staff can monitor the position of the trolley in real time.

[0030] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
