Description

Technical Field

[0001] This application relates to the field of automotive parts transfer, and more particularly to an automotive parts transfer and conveying device. Background Technology

[0002] In the automotive manufacturing industry, the transfer and transportation of auto parts is a crucial link in the production process. With the continuous development of the automotive industry, the requirements for the transfer and transportation of auto parts are becoming increasingly stringent. Efficient and stable transfer and transportation systems can ensure the smooth operation of the production line, improve production efficiency, and reduce production costs, which is of great significance for automotive manufacturers to enhance their market competitiveness. It can reduce damage to parts during transportation, guarantee product quality, and contribute to the automation and intelligent development of automotive production.

[0003] In existing technologies, various methods are typically employed to transfer and transport automotive parts. One common approach is to use simple lifting tools, such as hooks and ropes, to manually lift and move the parts to a designated location using a crane. This method is suitable for large and heavy automotive parts. In other cases, grippers combined with moving devices are used for parts transfer.

[0004] However, existing transfer and transportation methods have significant drawbacks. While hoisting can transport a large number of parts at once, its transfer accuracy is poor, and many parts cannot be directly hoisted; they must first be placed in a container and then the container is hoisted, which is very cumbersome. Furthermore, some parts are inconvenient to clamp due to their special shapes. For these types of parts, there is currently a transfer method that involves inserting a lifting rod into a through-hole in the part, then controlling the lifting rod to raise the part, and finally transferring the part.

[0005] However, since the diameter of the lifting rod is necessarily smaller than the diameter of the through hole of the component, and the diameter and hole shape of the through hole of different components may vary, the component may still move or sway relative to the lifting rod during transportation, resulting in poor stability and adaptability to different specifications of components. Summary of the Invention

[0006] To address the issues of poor adaptability and stability of traditional transfer devices, this application provides an automotive parts transfer and conveying device.

[0007] The automotive parts transfer and conveying device provided in this application adopts the following technical solution: An automotive parts transfer and conveying device, comprising: The clamping and fixing assembly includes a first driving unit and multiple clamping units, wherein each clamping unit includes a first driving component, an outer tube, an inner tube, multiple clamping modules, and multiple transmission modules; The outer tube is connected to the first driving unit, and the first driving unit is used to drive the outer tube to pass into the mounting hole on the workpiece. Multiple sets of clamping modules are circumferentially spaced on the outer tube, and each clamping module includes a support block and a clamping arm; the clamping arm is hinged to the end of the outer tube. The transmission module corresponds one-to-one with the clamping module; the inner tube is slidably disposed inside the outer tube and is connected to the support block and the clamping arm respectively through the transmission module; the first driving member is connected to the inner tube and is used to drive the inner tube to move so that the clamping module switches between a first state and a second state; In the first state, the plurality of clamping arms converge together; In the second state, the support block abuts against the inner wall of the mounting hole, and the clamping arm is located on one side of the workpiece wall. The conveying component is connected to the first drive unit.

[0008] By adopting the above technical solution, the first driving unit can drive the outer tube to pass through the workpiece mounting hole, and the first driving component drives the inner tube to move so that the clamping module switches between the first state and the second state. In the first state, the clamping arms come together to facilitate insertion into the mounting hole. In the second state, the support block abuts against the inner wall of the mounting hole, thereby supporting the mounting hole and preventing the workpiece from moving. The clamping arms are located on one side of the workpiece wall, which can effectively limit the workpiece and prevent the workpiece from detaching from the outer tube. The conveying component can transfer and transport the fixed workpiece.

[0009] Optionally, the clamping module further includes an abutment plate, and the inner tube is connected to the abutment plate via the transmission module; In the second state, the abutment plate and the clamping arm abut against the opposite sides of the workpiece wall.

[0010] By adopting the above technical solution, in the second state, the abutment plate and the clamping arm abut against the opposite sides of the workpiece wall, which can achieve stable clamping and fixing of the workpiece and improve the stability of the workpiece during the transfer and transportation of automotive parts.

[0011] Optionally, the outer tube is provided with a plurality of strip-shaped holes spaced apart along the circumference, and the transmission modules are respectively disposed in the strip-shaped holes; The transmission module includes a slider, a rack, and two connecting rods; Both the slider and the rack are mounted on the inner tube; the abutment plate is mounted on the slider. The clamping arm is provided with a serrated portion, which meshes with the rack. The two connecting rods are located on opposite sides of the support block, and one end of each connecting rod is hinged to the support block. One end of the connecting rod away from the support block is hinged to the slider, and the other end of the connecting rod away from the support block is hinged to the inner wall of the strip hole.

[0012] By adopting the above technical solution, the strip hole provides an installation position for the transmission module. When the inner tube moves, it drives the slider and rack to move. The rack meshes with the serrated part of the clamping arm, causing the clamping arm to rotate. The two connecting rods are respectively hinged to the support block, the slider and the inner wall of the strip hole, driving the support block to move. This enables the clamping module to switch between the first state and the second state, realizing the clamping and releasing action of the workpiece, which facilitates the fixing and transportation of automotive parts.

[0013] Optionally, the clamping module further includes a fixing plate and an elastic element; The fixing plate is disposed on the slider, and the fixing plate is located on the side of the abutment plate away from the workpiece; the abutment plate is slidably connected to the slider; the elastic element is located between the fixing plate and the abutment plate and is connected to both.

[0014] By adopting the above technical solution, the fixed plate is set on the slider and located on the side of the abutment plate away from the workpiece. The abutment plate is slidably connected to the slider. The elastic element connects the fixed plate and the abutment plate, so that the abutment plate can adaptively adjust the abutment pressure with the workpiece wall under the action of the elastic element, better adapt to workpieces of different sizes and shapes, and enhance the clamping stability of the workpiece. In addition, by setting the abutment plate to be movable relative to the slider, the abutment plate, clamping arm and support block can all contact the workpiece in the second state.

[0015] Optionally, the clamping arm has an abutment portion, which, in the second state, is used to abut against the wall of the workpiece; the abutment portion is hook-shaped and is also used to hook the workpiece.

[0016] By adopting the above technical solution, the first driving unit drives the outer tube to pass through the workpiece mounting hole, and the first driving component drives the inner tube to move so that the clamping module switches to the second state. At this time, the clamping arm abutting part abuts against the workpiece wall to achieve the limitation of the workpiece. The abutting part is hook-shaped, so that the abutting part can fix the workpiece by hooking the workpiece or hooking the container that holds the workpiece. For example, the workpiece can be hoisted in the first state, which enhances the applicability of the clamping module.

[0017] Optionally, the clamping arm has an abutment portion, and the abutment portion is provided with rollers; in the second state, the rollers are used to abut against the wall surface of the workpiece.

[0018] By adopting the above technical solution, the abutting part of the clamping arm is equipped with rollers.

[0019] Optionally, the end of the inner tube is provided with a suction cup.

[0020] By adopting the above technical solution, the inner tube can grip and fix the workpiece by adsorption, thus increasing the number of workpiece gripping methods.

[0028] The following is in conjunction with the appendix Figures 1 to 9 This application will be described in further detail. Example 1

[0029] like Figures 1 to 2 As shown in the figure, this application discloses an automotive parts transfer and conveying device, including: a conveying component 1 and a clamping and fixing component 2.

[0030] The conveying assembly 1 includes a base 11, a first movable seat 12, a second movable seat 13, a conveying drive 14, and a lifting drive 15. The first movable seat 12 is slidably disposed on the base 11. The conveying drive 14 is connected to the first movable seat 12 and is used to drive the first movable seat 12 to slide on the base 11. The lifting drive 15 is disposed on the first movable seat 12, and the second movable seat 13 is disposed below the first movable seat 12. The lifting drive 15 is connected to the second movable seat 13 and is used to drive the second movable seat 13 to lift and lower. The clamping and fixing assembly 2 is used to fix the workpiece 200. The clamping and fixing assembly 2 is disposed on the second movable seat 13. By cooperating with the conveying drive 14 and the lifting drive 15, the lifting and transfer of the workpiece 200 can be realized. In this embodiment, the lifting drive 15 can be a cylinder, and the conveying drive 14 is not strictly limited. For example, the conveying drive 14 can be a cylinder or a motor-screw drive mechanism. The method of driving the first movable seat 12 to move by a motor and a screw is relatively conventional and will not be described in detail.

[0031] The clamping and fixing assembly 2 includes multiple support units 21. Each support unit 21 includes a drive cylinder 211, a mounting plate 212, and a support rod 213. The drive cylinder 211 is mounted on the second movable seat 13. One end of the support rod 213 is connected to the mounting plate 212. The workpiece 200 has a mounting hole 201 for inserting the support rod 213. The drive cylinder 211 drives the support rod 213 into the mounting hole 201. At this time, the clamping and fixing assembly 2 is driven to rise by the lifting drive component 15, which can lift the workpiece 200 for subsequent transfer. Multiple support units 21 can be used to improve the stability of the workpiece 200. Example 2

[0032] The difference between this embodiment and Embodiment 1 is that: like Figures 3 to 9 As shown, the clamping and fixing assembly 2 includes a first driving unit 22, a rotary driving unit 23, and multiple sets of clamping units. The number of first driving units 22 and rotary driving units 23 can be multiple. Each first driving unit 22 is used to drive at least one set of clamping units to move closer to or further away from the workpiece 200; each rotary driving unit 23 is used to drive at least one set of clamping units to rotate to change the posture of the clamping units.

[0033] In this embodiment, the first driving unit 22, the rotary driving unit 23, and the clamping unit correspond one-to-one. The first driving unit 22 can be a cylinder. The rotary driving unit 23 includes a third movable seat 231, a mounting frame 232, and a rotary driving motor 233. The third movable seat 231 is slidably mounted on the second movable seat 13, and the mounting frame 232 is rotatably connected to the third movable seat 231. The rotary driving motor 233 is mounted on the third movable seat 231 and is drively connected to the mounting frame 232. The first driving unit 22 is mounted on the second movable seat 13 and connected to the third movable seat 231; the clamping unit is mounted on the mounting frame 232.

[0034] The clamping unit includes a first driving member 24, an outer tube 25, an inner tube 26, multiple clamping modules 27, and multiple transmission modules 28. The outer tube 25 is mounted on a mounting bracket 232, and the inner tube 26 is slidably disposed coaxially inside the outer tube 25. One end of the inner tube 26 is connected to the first driving member 24 mounted on the mounting bracket 232. The first driving member 24 is used to drive the inner tube 26 to move along the axial direction of the outer tube 25. The first driving member 24 may be a cylinder.

[0035] like Figures 6 to 9 As shown, the clamping module 27 and the transmission module 28 correspond one-to-one. Multiple sets of clamping modules 27 are evenly spaced circumferentially on the outer tube 25. The clamping module 27 includes clamping arms 271, which are hinged to one end of the outer tube 25. The clamping arms 271 have serrated portions 2711. The transmission module 28 includes a rack 281, which is disposed on the inner tube 26 and engages with the serrated portions 2711. By driving the inner tube 26 to move, the multiple clamping arms 271 can be flipped, thereby allowing the multiple clamping arms 271 to come together or move away from each other. The multiple clamping arms 271 can fix the workpiece 200 by directly gripping it.

[0036] Furthermore, a suction cup is provided at the end of the inner tube 26, and an air pump is connected to the inner tube 26 via a pipe. The air pump creates negative pressure, allowing the inner tube 26 to fix the workpiece 200 by suction. When suctioning the workpiece 200, the inner tube 26 can be rotated to a vertical position by the rotation drive unit 23.

[0037] Furthermore, the clamping and fixing assembly 2 can also fix the workpiece 200 by lifting. Specifically, by inserting the outer tube 25 into the mounting hole 201 and then lifting it, the workpiece 200 can be lifted.

[0038] The clamping module 27 also includes a support block 272, an abutment plate 273, a fixing plate 274, an elastic element 275, and a guide rod 276; the outer tube 25 is provided with a plurality of strip holes 251 spaced apart along the circumference, and the transmission module 28 is correspondingly arranged in the strip holes 251. The transmission module 28 also includes a slider 282 and two connecting rods 283.

[0039] A slider 282 is mounted on the inner tube 26, a fixing plate 274 is mounted on the slider 282, and an abutment plate 273 is slidably mounted on the slider 282. When the outer tube 25 is inserted into the mounting hole 201, the fixing plate 274 is located on the side of the abutment plate 273 away from the workpiece 200. An elastic element 275 is located between the fixing plate 274 and the abutment plate 273 and is connected to both. In this embodiment, the elastic element 275 can be a spring. One end of the guide rod 276 is connected to the abutment plate 273, and the other end is slidably connected to the fixing plate 274. The elastic element 275 is sleeved on the guide rod 276.

[0040] The support block 272 and the two connecting rods 283 are located on the side of the slider 282 near the clamping arm 271. The two connecting rods 283 are located on opposite sides of the support block 272, and one end of each connecting rod 283 is hinged to the support block 272. One end of one connecting rod 283 away from the support block 272 is hinged to the slider 282, and the other end of the connecting rod 283 away from the support block 272 is hinged to the inner wall of the strip hole 251.

[0041] like Figures 6 to 9 As shown, after the outer tube 25 is inserted into the mounting hole 201, the inner tube 26 is moved by the first driving member 24, which can switch the clamping module 27 between the first state and the second state.

[0042] In the first state, multiple clamping arms 271 are clustered together, and there is a gap between the support block 272 and the inner wall of the mounting block. During the transition from the first state to the second state, the inner tube 26 moves the slider 282 and rack 281, and the abutment plate 273 gradually approaches the side of the workpiece 200 with the mounting hole 201; the clamping arms 271 gradually approach the other side of the workpiece 200 with the mounting hole 201 by flipping; and the slider 282, during its movement, presses against the connecting rod 283, thereby forcing the support block 272 to gradually approach the inner wall of the mounting hole 201. Upon reaching the second state, the support block 272 abuts against the inner wall of the mounting hole 201, and the abutment plate 273 and clamping arms 271 abut against the opposite sides of the workpiece 200 with the mounting hole 201. The support block 272 supports the inner wall of the mounting hole 201, while the abutment plate 273 and clamping arms 271 clamp and limit the workpiece 200. The above-mentioned design effectively prevents the workpiece 200 from shaking during transport. The support block 272 is equipped with a flexible pad to prevent damage to the workpiece 200.

[0043] The clamping arm 271 has an abutment portion 2712, which, in the second state, is used to abut against the wall surface of the workpiece 200 having mounting holes 201.

[0044] In this embodiment, the clamping and fixing assembly 2 can also fix the workpiece 200 by means of hoisting. Specifically, in this embodiment, the abutment portion 2712 is hook-shaped. The abutment portion 2712 can be used to hook the workpiece 200 or the container containing the workpiece 200.

[0045] In some embodiments, the abutment portion 2712 is provided with rollers. In the second state, the rollers are used to abut against the wall surface of the workpiece 200 with the mounting hole 201, thereby reducing friction.

[0046] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
