Description

Technical Field

[0001] The utility model relates to the technical field of automobile manufacturing, in particular to an automobile top cover clamp. Background Art

[0002] Before installing the car roof, a crossbeam needs to be installed at the front and rear of the roof, and then the KUKA robot will weld and fix the crossbeam. After welding, both sides of the roof need to be wiped because there will be a layer of protective oil film on the surface of the galvanized steel plate. Both sides of the roof also need to be wiped to remove the oil film. After wiping, it is placed on the roof for welding and fixing. During this process, the cooperation of the roof clamp is required to realize the movement of the car roof.

[0003] The utility model with announcement number CN213614924U discloses a positioning gripper for processing a car roof, which comprises: a bracket, a clamping unit, a suction cup unit, and a gun changing disc unit, wherein the suction cup units are respectively arranged on the first to fourth side brackets of the bracket.

[0004] Due to the oil film on the surface of the car roof, the surface of the car roof is easily stained with dust. When the vacuum suction cup adsorbs the car roof, the dust is easy to adhere to the surface of the vacuum suction cup. When too much dust accumulates on the surface of the vacuum suction cup, the vacuum suction cup and the car roof are not in close contact, resulting in air leakage during vacuum adsorption, resulting in vacuum adsorption failure, which is not conducive to the safe transportation of the car roof. Therefore, these debris need to be cleaned up.

[0005] As in the above-mentioned technical solution, there is no structure for cleaning dust at the vacuum suction cup. When too much dust accumulates on the surface of the vacuum suction cup, it is easy to cause the vacuum suction cup to be in loose contact with the car roof, resulting in air leakage during vacuum adsorption, which can easily lead to vacuum adsorption failure and is not conducive to the safe transportation of the car roof.

DETAILED DESCRIPTION

[0049] The following will be combined with the specific implementation of the utility model to clearly and completely describe the technical solution in the utility model. Obviously, the described implementation is only a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0050] like Figure 1-4 As shown, a car roof clamp of the utility model comprises a bracket 1, a suction cup unit 2, a mounting seat 5 and a pneumatic clamp 6.

[0051] Among them, the bracket 1 is placed horizontally, and the bracket 1 is welded into a frame shape by lightweight aluminum alloy square tubes. A mounting seat 5 is fixedly arranged in the middle position of the top of the bracket 1. The mounting seat 5 is in the shape of a flange and is used to connect the execution end of the robot arm.

[0052] The suction cup unit 2 is vertically slidably arranged on the bracket 1 and is used to absorb the top of the car roof. Figure 1 The front view of the clamp in the clamping state is shown. Figure 2 The suction cup unit 2 is arranged in a matrix at four places on the bracket 1, and the car roof is not drawn in the figure. When clamping, the suction end of the suction cup unit 2 moves downward and contacts with the top surface of the car roof, and then the suction end of the suction cup unit 2 is fixedly connected to the top of the car roof by vacuum adsorption. Specifically, the suction cup unit 2 includes a lifting cylinder 21 and a vacuum suction cup 22, wherein the lifting cylinder 21 vertically penetrates the bracket 1 and is fixedly connected, and the vacuum suction cup 22 is fixedly arranged on the output end of the lifting cylinder 21 and is connected to the vacuum pumping equipment in the assembly workshop through a pipeline. When clamping, the output end of the vacuum suction cup 22 extends downward to drive the vacuum suction cup 22 to contact with the car roof, and the vacuum pumping equipment in the assembly workshop draws vacuum to make negative pressure in the vacuum suction cup 22, thereby realizing vacuum adsorption and fixation of the car roof.

[0053] A plurality of pneumatic clamps 6 are provided in a matrix on the side of the bracket 1 to clamp the bottom of the car roof and cooperate with the suction cup unit 2 up and down to achieve a stable clamping of the car roof. Specifically, Figure 2 As shown, four pneumatic clamps 6 are arranged in a matrix on the side of the bracket 1, and each pneumatic clamp 6 includes a clamp plate 61 and a flip cylinder 62, wherein one end of the clamp plate 61 is arranged below the bracket 1, and the other end is hinged to the side of the bracket 1, and one end of the flip cylinder 62 is hinged to the side of the bracket 1, and the output end of the flip cylinder 62 is hinged to the side of the clamp plate 61. When clamping, as shown in FIG. Figure 1 As shown, the output end of the flip cylinder 62 extends out to drive the clamping plate 61 to flip, so that the lower end of the clamping plate 61 is abutted against the bottom edge of the automobile roof.

[0054] Due to the clamping force, the clamping plate 61 may damage the bottom edge of the car roof. To prevent this from happening, an airbag 63 is fixedly arranged on the end of the clamping plate 61 away from the bracket 1, that is, the airbag 63 is arranged on the clamping surface to achieve clamping protection.

[0055] Since there is an oil film on the surface of the car top cover, the surface of the car top cover is easily stained with some dust. When the vacuum suction cup 22 adsorbs the car top cover, the dust is easy to adhere to the surface of the vacuum suction cup 22. When too much dust accumulates on the surface of the vacuum suction cup 22, it will cause the vacuum suction cup 22 to be in loose contact with the car top cover, causing air leakage during vacuum, resulting in vacuum adsorption failure, which is not conducive to the safe transportation of the car top cover, so it is necessary to clean up these debris.

[0056] To solve the above problems, a car roof clamp of the utility model also includes a driving unit 3 and a purge unit 4. A group of driving units 3 and purge units 4 are arranged on one side of each suction cup unit 2. All the purge units 4 are respectively connected to the air outlet of the air pump through pipes. The surface of the vacuum suction cup 22 is cleaned by the purge unit 4, which can improve the contact effect between the vacuum suction cup 22 and the car roof, prevent air leakage, improve the vacuum adsorption effect, and facilitate the safe transportation of the car roof.

[0057] Specifically, one end of the driving unit 3 is fixedly arranged at the bottom of the bracket 1, and the other end is fixedly connected to the purge unit 4. The driving unit 3 is used to drive the purge unit 4 to reciprocate in the horizontal direction to selectively move the purge unit 4 to the bottom of the suction cup unit 2. One end of the purge unit 4 is used to connect to the air pump, and the other end is used to purge the surface of the suction cup unit 2. Figure 3 As shown, when the transfer is completed, the vacuum suction cup 22 moves up to the highest point. At this time, the driving unit 3 drives the purge unit 4 to move to the bottom of the vacuum suction cup 22, and the compressed air in the air pump is blown to the vacuum suction cup 22 through the purge unit 4 to achieve purge.

[0058] The driving unit 3 includes a mounting plate 31 and a translation cylinder 32, wherein the mounting plate 31 is arranged on the side of the suction cup unit 2 and fixedly arranged at the bottom of the bracket 1, the translation cylinder 32 is horizontally arranged, and the translation cylinder 32 is fixedly arranged on the side of the mounting plate 31, and the output end of the translation cylinder 32 is fixedly connected to the purge unit 4. When the output end of the translation cylinder 32 is extended, the purge unit 4 is driven to translate to the bottom of the vacuum suction cup 22, and when the output end of the translation cylinder 32 is retracted, the purge unit 4 is driven to move away from under the vacuum suction cup 22.

[0059] like Figure 4 As shown, the purge unit 4 includes a nozzle 41 and an air inlet pipe joint 42, wherein the side of the nozzle 41 is threadedly connected and communicated with one end of the air inlet pipe joint 42, the side of the nozzle 41 is fixedly connected to the output end of the translation cylinder 32, a plurality of air jets 401 are evenly distributed on the top of the nozzle 41, the air jets 401 face the bottom surface of the vacuum suction cup 22, the air inlet pipe joint 42 is connected to the air pump through a pipeline, when purge is needed, the compressed air of the air pump is transported from the pipeline to the air inlet pipe joint 42, then enters the nozzle 41, and finally is sprayed from the plurality of air jets 401 to the bottom surface of the vacuum suction cup 22 for purge, thereby cleaning the surface of the vacuum suction cup 22.

[0060] To improve the cleaning effect, the purge unit 4 further includes a liquid inlet pipe joint 43, a liquid pump 44 and a liquid storage tank 45, wherein Figure 3As shown, one end of the liquid inlet pipe joint 43 is fixedly connected to the side of the air inlet pipe joint 42 and is connected, and the other end is connected to the liquid outlet of the liquid pump 44 through a pipeline. The liquid pump 44 is fixedly arranged on the side of the liquid storage tank 45, and the liquid inlet of the liquid pump 44 is connected to the liquid storage tank 45 through a pipeline. The liquid storage tank 45 is fixedly arranged on the top of the bracket 1, and a liquid injection port is provided on one side of the top of the liquid storage tank 45. An end cover is provided on the liquid injection port. Cleaning liquid such as industrial alcohol or detergent is injected into the liquid storage tank 45 through the liquid injection port. When cleaning the vacuum suction cup 22, during the purging process, the cleaning liquid in the liquid storage tank 45 is sucked by the liquid pump 44, and then sent to the liquid inlet pipe joint 43 through the pipeline. As the compressed air flows, the cleaning liquid is mixed into the compressed air, and is sprayed from the plurality of air jets 401 to the bottom surface of the vacuum suction cup 22 along with the compressed air, thereby realizing wet cleaning and improving the cleaning effect.

[0061] In the above structure, the liquid inlet pipe joint 43 is inclined at the side of the air inlet pipe joint 42, and the inclination angle is 30-60 degrees, so that the cleaning liquid can enter the air inlet pipe joint 42 more easily. All the liquid inlet pipe joints 43 are connected to the liquid outlet of the liquid pump 44 through pipes, and the above pipes are not drawn in the figure.

[0062] The method of using the automobile top cover clamp of the utility model is as follows:

[0063] like Figure 1 As shown, in the clamping state, the output end of the lifting cylinder 21 extends out to drive the vacuum suction cup 22 to press against the top of the car roof, and then the vacuum suction cup 22 vacuum-absorbs the car roof, and the output end of the flipping cylinder 62 extends out to drive the clamping plate 61 to flip and clamp the bottom edge of the car roof downward. In this state, the nozzle 41 is on the side of the suction cup unit 2.

[0064] like Figure 3 As shown, in the purging state, the vacuum suction cup 22 rises to the top, and the pneumatic clamp 6 opens to both sides. At this time, the nozzle 41 is driven to translate by the translation cylinder 32 to move the nozzle 41 to the bottom of the vacuum suction cup 22, and compressed air is delivered to the nozzle 41 by the air pump. At the same time, the cleaning liquid is delivered to the nozzle 41 by the liquid pump 44. The bottom of the vacuum suction cup 22 is cleaned by compressed air and cleaning liquid. After cleaning, the nozzle 41 is driven to translate by the translation cylinder 32 to move the nozzle 41 to the side of the vacuum suction cup 22.

[0065] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
