Description

Technical Field

[0001] This utility model belongs to the field of mechanical feeding technology, and in particular relates to a workpiece feeding trolley. Background Technology

[0002] In modern manufacturing, robotic arms play a crucial role in workpiece handling and processing. Traditional workpiece loading methods largely rely on manual operation, with workers placing workpieces in designated areas for the robotic arm to grasp. However, this manual loading model has several drawbacks. Manual placement makes it difficult to ensure precise positioning of the workpiece at the robotic arm's preset gripping point every time. Positional deviations often lead to gripping failures, reducing production efficiency. Frequent gripping errors can also damage both the robotic arm and the workpiece, increasing equipment maintenance costs and workpiece scrap rates. Furthermore, with product diversification, production lines need to handle workpieces of different specifications. Traditional loading devices typically require changing the loading fixture for different workpiece sizes, increasing manufacturing costs and production line downtime, thus affecting production continuity and economic efficiency.

[0003] In summary, existing technologies suffer from poor positioning accuracy, low loading efficiency, and insufficient compatibility with workpieces of different specifications during the workpiece loading process. Utility Model Content

[0004] The purpose of this utility model is to provide a workpiece loading trolley that solves the problems of poor positioning accuracy, low loading efficiency, and insufficient compatibility with workpieces of different specifications in the existing workpiece loading process.

[0005] This utility model is achieved through the following technical solution:

[0006] A workpiece loading trolley, comprising:

[0007] The frame has a push rod on one side, casters at the bottom, and a placement plate on the top.

[0008] The placement plate is distributed with multiple sets of circumferentially arrayed guide sleeves, which are installed through the placement plate.

[0009] The guide sleeves in the same group are equidistant from the center of the placement plate; the positions of guide sleeves in different groups are designed according to the size of the workpiece.

[0010] A guide rod is movably mounted in the guide sleeve, and the height of the guide rod is higher than that of the workpiece to be installed.

[0011] Furthermore, the placement plate is also provided with support columns, which are arranged inside the guide sleeve to support the workpiece.

[0012] Furthermore, the main body of the guide rod is a cylinder, and the top of the cylinder is pre-machined into a cone.

[0013] Furthermore, the bottom of the guide sleeve and the guide rod are provided with corresponding insertion holes, and the guide sleeve and the guide rod are fixed by inserting a pull ring-type knob plunger into the insertion hole.

[0014] Furthermore, the casters include two swivel casters and two fixed casters. The two swivel casters are symmetrically arranged at both ends of the frame near the push rod, and the two fixed casters are symmetrically arranged at both ends of the opposite side of the swivel casters. A braking device is also provided above the swivel casters.

[0015] Furthermore, the braking device includes a pedal, one end of which is elastically connected to the connection part of the swivel caster, and the other end of the pedal has an oblique brake groove extending below it.

[0016] When the pedal is pressed down, the angled brake groove is used to lock the swivel casters.

[0017] Furthermore, a guide device is also provided at the bottom of the frame. The guide device is symmetrically arranged between two swivel casters and two fixed casters. The guide device includes a connecting plate and two guide wheels. One end of the connecting plate is connected to the frame and the other end extends away from the frame to fix the two guide wheels. The two guide wheels are horizontally arranged and have a gap between them.

[0018] Furthermore, the frame is a rectangular frame structure, and the guide sleeves are provided in three sets, which are located at the four corners near the placement plate, with the three guide sleeves at each corner arranged adjacent to each other.

[0019] Furthermore, with the horizontal center line of the placement plate as the baseline, the angle between the setting range of each set of guide sleeves and the baseline is maintained at 30° to 45°.

[0020] Compared with the prior art, the present invention has the following beneficial technical effects:

[0021] This utility model discloses a workpiece loading trolley. Multiple sets of guide sleeves are provided on the placement plate of the trolley body, and guide rods are movably installed within each guide sleeve. The positions of different types of guide sleeves are designed according to the size of the workpiece. When placing a workpiece, simply insert the guide rod into the corresponding guide sleeve according to the workpiece's size to achieve workpiece positioning. In use, simply move the trolley to the preset position, and the robotic arm can accurately grasp the workpiece, improving the positioning accuracy and greatly facilitating the robotic arm's grasping, thereby increasing loading efficiency. The design of multiple sets of guide sleeves adapts to the positioning of workpieces of different specifications, thus solving the problem of insufficient compatibility in existing loading devices.

[0022] Furthermore, multiple support columns are provided inside the guide sleeve. By placing the workpiece on the support columns, the contact between the workpiece and the placement plate is reduced, thus preventing workpiece wear.

[0023] Furthermore, by setting the main body of the guide rod as a cylinder, the positioning of the workpiece can be avoided after the guide rod rotates. When the workpiece is placed from top to bottom, the cone-shaped design at the top of the guide rod makes it easier to place the workpiece on the workpiece loading trolley without affecting its positioning accuracy.

[0024] Furthermore, the guide rod on the placement plate can be installed in different positions via a guide sleeve and a pull-ring type knob plunger. Attached Figure Description

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit it; that is, the described embodiments are only a part of, and not all, of the embodiments of this utility model.

[0033] The components described and illustrated in the accompanying drawings and embodiments of this utility model can be arranged and designed in various different configurations. Therefore, the detailed description of the embodiments of this utility model provided in the following drawings is not intended to limit the scope of the claimed utility model, but merely to illustrate one selected embodiment of the utility model. All other embodiments obtained by those skilled in the art based on the accompanying drawings and embodiments of this utility model without inventive effort are within the protection scope of this utility model.

[0034] It should be noted that the terms “comprising,” “including,” or any other variations are intended to cover non-exclusive inclusion, such that a process, element, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to the process, element, method, article, or apparatus.

[0035] The features and performance of this utility model will be further described in detail below with reference to the embodiments.

[0036] Please see Figures 1-4 This utility model provides a workpiece loading trolley, including a frame 1 and a guide rod 4; a push rod 11 is provided on one side of the frame 1, and casters are installed at the bottom of the frame 1 by bolts 8. A placement plate 12 is installed on the top of the frame 1, and support columns 5 and guide sleeves 3 are distributed on the placement plate 12. The support columns 5 are used to place and support the workpiece 10 so that it does not contact the placement plate 12. By placing the workpiece 10 on the support columns 5, the contact between the workpiece 10 and the placement plate 12 is reduced, and the workpiece wear is prevented.

[0037] like Figure 4 As shown, the guide sleeve 3 passes through the placement plate 12, and the guide rod 4 is inserted into the guide sleeve 3. The placement plate 2 and the guide sleeve 3 fix the guide rod 4, thereby limiting the workpiece, improving the positioning accuracy of the workpiece, greatly facilitating the gripping of the robot, and improving the efficiency of loading.

[0038] like Figure 4 As shown, the main body of the guide rod 4 is a cylinder, and a cone extends axially from the top of the cylinder. In this embodiment, the cone is a truncated cone. Setting the main body of the guide rod 4 as a cylinder can avoid the influence of the guide rod 4 on the workpiece positioning after rotation. In addition, when the workpiece 10 is placed from top to bottom, the cone at the top of the guide rod 4 can make it easier to place the workpiece 10 on the workpiece loading trolley without affecting its positioning accuracy. The bottom end of the guide rod 4 is detachably installed on the placement plate 12 through the guide sleeve 3, and the height of the guide rod 4 is higher than that of the workpiece 10 to achieve effective limiting.

[0039] Furthermore, the frame 1 is a rectangular frame structure. Since the same car needs to adapt to products and tooling of various diameters, the guide sleeves 3 need to be distributed in a distributed layout design.

[0040] Let's take three diameters as examples to illustrate, such as... Figure 6 As shown, three guide sleeves 3 are symmetrically arranged at the four corners of the placement plate 12, and they are arranged adjacent to each other. The middle guide sleeve 3 is close to the center of the placement plate 12. In this embodiment, the horizontal center line of the placement plate 12 is used as the reference line, and the guide sleeve 3 is kept within the range of 30° to 45°. The distance between the guide sleeve 3 and the center of the placement plate 12 is set according to the size of the workpiece to prevent interference with the robot arm when it is gripped, as well as interference that exists when the guide sleeve 3 is installed, and does not affect the positioning of the workpiece on the workpiece loading trolley.

[0041] In this embodiment, as Figure 6 As shown, the frame 1 is provided with multiple guide sleeves 3 arranged in the circumferential direction with different radii. By placing the guide rod 4 into different guide sleeves 3, the workpieces of different specifications can be limited, thereby solving the problem of insufficient compatibility of the existing feeding device.

[0042] Furthermore, the bottom of the guide sleeve 3 and the guide rod 4 are provided with corresponding insertion holes. The guide sleeve 3 and the guide rod 4 are fixed by inserting the pull ring type knob plunger 9 into the insertion hole to realize the cyclic use of the guide rod 4.

[0043] Furthermore, the casters include two swivel casters 6 and two fixed casters 7. The two swivel casters 6 are symmetrically arranged at both ends of the frame 1 near the push rod 11, and the two fixed casters 7 are symmetrically arranged at both ends of the opposite side of the swivel casters 6. The brake device 61 is installed above the swivel casters 6. In this embodiment, the swivel casters 6 are connected to the connecting part 62 through the wheel axle. The connecting part 62 is used to connect the frame 1. The brake device 61 includes a pedal 611. One end of the pedal 611 is elastically connected to the connecting part 62 of the swivel caster 6, and the other end of the pedal 611 has an inclined brake groove 612 extending below it. By pressing down on the pedal 611, the workpiece loading trolley can be positioned in the forward and backward direction.

[0044] Furthermore, a guide device is also provided at the bottom of the frame 1, such as... Figure 1 and Figure 3 As shown, the guide device is symmetrically arranged between two omnidirectional casters 6 and two directional casters 7. The guide device includes a connecting plate and two guide wheels 2. One end of the connecting plate is connected to the frame 1 and the other end extends away from the frame 1 to fix the two guide wheels 2. In this embodiment, the guide wheels 2 are fixed to the connecting plate by their own screws. The two guide wheels 2 are arranged horizontally with a gap between them. With the help of a clamping device corresponding to the gap set on the ground of the loading area, the left and right positioning of the workpiece loading trolley is realized.

[0045] Work process:

[0046] During use, firstly, guide rod 4 is placed into guide sleeve 3 that is suitable for the workpiece specification. Then, guide sleeve 3 and guide rod 4 are fixed by pull ring type knob plunger 9. Then, the operator places workpiece 10 on support column 5. Workpiece 10 is positioned by guide rod 4 and pushes push rod 11 to move workpiece loading trolley. When turning is required, the direction of travel of frame 1 is changed by using the steering function of directional caster 7 and universal caster 6 to push workpiece loading trolley to loading position. Then, the position of workpiece loading trolley is fixed by using brake device 61 and guide device on universal caster 6, waiting for robot arm to grab workpiece 10.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the specific implementation of this utility model. Any modifications or equivalent substitutions that do not depart from the spirit and scope of this utility model should be covered within the protection scope of the claims of this utility model.
