Description

Technical Field

[0001] This utility model relates to the field of gravity wheel rim processing technology, and in particular to a wheel rim transfer device at the end of a powder coating line. Background Technology

[0002] In the production process of automotive wheel rims, the rims first undergo surface powder coating treatment on a powder coating line, and then are transferred to a heat curing line for coating curing. In existing technology, the transfer of wheel rims between the two production lines generally relies on manual handling, which has the following significant drawbacks:

[0003] High labor intensity: The wheel rims are quite heavy (a single wheel rim usually weighs 5-20kg), and manual handling requires a lot of physical strength. Especially in large-scale production scenarios, workers are prone to fatigue, which leads to a decrease in work efficiency.

[0004] Low production efficiency: Manual handling requires frequent back-and-forth between two production lines, which is time-consuming and affected by human factors (such as handling rhythm and operator proficiency), making it difficult to match the continuous operation rhythm of automated production lines and easily creating production bottlenecks.

[0005] High production costs: Manual handling requires a large number of operators, which increases the company's labor costs; at the same time, rework or scrap due to product damage further increases production costs.

[0006] Limitations of existing automated transfer solutions: Some companies have tried using robotic arms for transfer, but traditional robotic arms mostly use rigid clamping structures, which cannot adapt to the size differences of different rim sizes, and lack a buffering mechanism during clamping, so there is still a risk of scratches. Utility Model Content

[0007] The purpose of this invention is to provide a rim transfer device at the end of a powder coating line, which replaces manual labor in rim transfer through the coordinated movement of a robotic arm and a rim clamping mechanism, thereby reducing labor intensity and improving production efficiency.

[0008] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0009] A rim transfer device at the end of a powder coating line includes a robotic arm and a rim clamping mechanism. The rim clamping mechanism includes a base plate with multiple circumferentially distributed radial telescopic arms and a drive assembly that drives the multiple radial telescopic arms to move synchronously. Each radial telescopic arm has a clamping disc connected to its end. The base plate is fixedly connected to a connecting plate via multiple connecting rods, and the connecting plate is fixed to the robotic arm. The robotic arm can drive the rim clamping mechanism to move up, down, and translate. When a rim needs to be clamped, the robotic arm moves the rim clamping mechanism to the corresponding rim position. At this time, the multiple clamping discs are evenly distributed on the outer side of the rim. The drive assembly drives the multiple radial telescopic arms to move inward simultaneously. The radial telescopic arms drive the clamping discs to move inward, thereby clamping the rim between the multiple clamping discs, and then the rim can be transferred. This realizes the automatic transfer of the rim, which can reduce the labor intensity of workers and reduce production costs.

[0010] The present invention is further configured such that: the radial telescopic arm includes a radially arranged rectangular bar and a vertically arranged pull rod, the pull rod is inserted into the outer end of the rectangular bar, and the clamping plate is inserted into the bottom of the pull rod; both ends of the pull rod are fixed with blocks, and a compression spring is clamped between the outer end of the rectangular bar and the clamping plate;

[0011] The middle part of the rectangular strip is inserted into the rectangular guide sleeve, and the rectangular guide sleeve is fixed on the base plate.

[0012] The pull rod can be moved up and down by the compression spring. When placing the rim, it can prevent relative slippage between the clamping plate and the rim, thus avoiding scratches. That is, after the rim is placed in place, the rim cannot continue to move down, but the rim clamping mechanism continues to move down under the action of the robot. The clamping plate is sleeved on the pull rod, so that the clamping plate does not move when the pull rod moves down, thus avoiding scratches.

[0013] The present invention is further configured such that: the driving component includes a waist-shaped ring fixed to the inner end of the rectangular bar, and the waist-shaped ring and the rectangular bar are arranged in an "L" shape; the waist-shaped ring is inserted into a short shaft, the short shaft is fixed to a gear, and the gear is rotatably connected to the base plate;

[0014] The gear meshes with a drive wheel, which is connected to a motor that drives it to rotate. The motor is fixed on the base plate.

[0015] The motor drives the drive wheel to rotate, the drive wheel drives the gear to rotate, the gear drives the short shaft to move, and the short shaft and the waist ring work together to drive the rectangular bar to move along the rectangular guide sleeve. The rectangular bar drives the clamping plate to move through the pull rod, thereby realizing the work of clamping the rim or releasing the rim.

[0016] The present invention is further configured such that: the clamping disk includes an upper conical disk and a lower conical disk arranged symmetrically, a support disk is clamped between the upper conical disk and the lower conical disk, and the outer edge of the support disk is formed with an arc surface.

[0017] When clamped, the support plate is located below the upper flange of the rim. The arc surface design reduces the contact area between the outer end of the clamping plate and the outer wall of the rim, and even if relative sliding occurs, it will not scratch the rim.

[0018] The present invention is further configured such that: a first damping sleeve is fixed inside the drive wheel, and a second damping sleeve is fixed on the motor shaft of the motor, with the first damping sleeve inserted outside the second damping sleeve.

[0019] Once the clamping disc is against the rim, if the motor continues to generate power, the first and second damping sleeves can slide relative to each other, thus preventing the clamping disc from moving further inward and preventing excessive clamping force from damaging or deforming the rim.

[0020] The outstanding effect of this utility model is:

[0021] Compared with existing technologies, the coordinated movement of the robotic arm and the rim clamping mechanism replaces manual labor in rim transfer, reducing labor intensity and improving production efficiency.

[0022] The triple design of spring buffer structure, arc-shaped clamping plate and damping overload protection device prevents the rim from being scratched or squeezed and deformed during clamping.

[0023] The circumferentially distributed radial telescopic arm and its radial movement can adapt to the clamping of rims of different diameters, improving compatibility and practicality. Attached Figure Description

[0032] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0033] The following is for reference Figures 1 to 3 The present invention will be described as follows:

[0034] A rim transfer device at the end of a powder coating line, such as Figure 1 As shown, the device includes a robotic arm 1 and a rim clamping mechanism 2. The robotic arm is a six-axis industrial robot, and its coordinate positioning and motion trajectory planning are achieved through a PLC control system. The rim clamping mechanism 2 includes a base plate 21, on which are provided multiple circumferentially distributed radial telescopic arms 22 and a drive assembly 23 that drives the multiple radial telescopic arms 22 to move synchronously. Each radial telescopic arm 22 has a clamping plate 24 connected to its end. The base plate 21 is fixedly connected to a connecting plate 26 via multiple connecting rods 25, and the connecting plate 26 is fixed to the robotic arm. The robotic arm can drive the rim clamping mechanism to rise, fall, and translate. When a rim needs to be clamped, the robotic arm moves the rim clamping mechanism to the corresponding rim position. At this time, multiple clamping plates are evenly distributed on the outer side of the rim. The drive assembly drives the multiple radial telescopic arms to move inward simultaneously. The radial telescopic arms drive the clamping plates to move inward, thereby clamping the rim between the multiple clamping plates. Then, the rim can be transferred, thus realizing the automatic transfer of the rim, reducing the labor intensity of workers and reducing production costs.

[0035] The radial telescopic arm 22 includes a radially arranged rectangular bar 221 and a vertically arranged pull rod 222. The pull rod 222 is inserted into the outer end of the rectangular bar 221, and the clamping plate 24 is inserted into the bottom of the pull rod 222. The two ends of the pull rod 222 are fixed with blocks 223, and a compression spring 224 is clamped between the outer end of the rectangular bar 221 and the clamping plate 24.

[0036] The middle part of the rectangular strip 221 is inserted into the rectangular guide sleeve 225, and the rectangular guide sleeve 225 is fixed on the base plate 21.

[0037] The pull rod can be moved up and down by the compression spring. When placing the rim, it can prevent relative slippage between the clamping plate and the rim, thus avoiding scratches. That is, after the rim is placed in place, the rim cannot continue to move down, but the rim clamping mechanism continues to move down under the action of the robot. The clamping plate is sleeved on the pull rod, so that the clamping plate does not move when the pull rod moves down, thus avoiding scratches.

[0038] The clamping disk 24 includes an upper conical disk 241 and a lower conical disk 242 arranged symmetrically. A support disk 243 is clamped between the upper conical disk 241 and the lower conical disk 242. The outer edge of the support disk 243 is formed with an arc surface 244.

[0039] When clamped, the support plate is located below the upper flange of the rim. The arc surface design reduces the contact area between the outer end of the clamping plate and the outer wall of the rim, and even if relative sliding occurs, it will not scratch the rim.

[0040] like Figure 2 As shown, the drive assembly 23 includes a waist-shaped ring 231 fixed to the inner end of the rectangular bar 221, and the waist-shaped ring 231 and the rectangular bar 221 are arranged in an "L" shape; the waist-shaped ring 231 is inserted into the short shaft 232, the short shaft 232 is fixed to the gear 233, and the gear 233 is rotatably connected to the base plate 21;

[0041] The gear 233 meshes with a drive wheel 234, which is connected to a motor 235 that drives it to rotate. The motor 235 is fixed on the base plate 21.

[0042] The motor drives the drive wheel to rotate, the drive wheel drives the gear to rotate, the gear drives the short shaft to move, and the short shaft and the waist ring work together to drive the rectangular bar to move along the rectangular guide sleeve. The rectangular bar drives the clamping plate to move through the pull rod, thereby realizing the work of clamping the rim or releasing the rim.

[0043] like Figure 3 As shown, a first damping sleeve 236 is fixed inside the drive wheel 234, and a second damping sleeve 237 is fixed on the motor shaft of the motor 235. The first damping sleeve 236 is inserted into the second damping sleeve 237.

[0044] Once the clamping disc is against the rim, if the motor continues to generate power, the first and second damping sleeves can slide relative to each other, thus preventing the clamping disc from moving further inward and preventing excessive clamping force from damaging or deforming the rim.

[0045] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model. These improvements and modifications assumed above should also be considered within the protection scope of the present utility model.
