[0034] The transportation device for door inspection of the invention is adopted. First, the door workpiece is placed on the first placement tray 22 by a manipulator, and then the first placement tray 22 or the second placement tray is transported from the placement part 2 to the surface detection part 3 by the transportation part 4. Then, the door workpiece is inspected by the surface detection component 32. At the same time, the transportation part 4 can also transport the first placement tray 22 or the second placement tray from the surface detection part 3 to the placement part 2. With such an arrangement, the reciprocating motion of the first placement tray 22 or the second placement tray can be realized, which improves the surface inspection efficiency.

The transportation device for door inspection of the present invention effectively solves the problem of poor production efficiency and qualified rate in the prior art by manual transportation.

[0035] In some embodiments, the transport unit 4 includes a transport frame 41 and a conveying assembly 42 and a return assembly 43 disposed on the transport frame 41. The transport frame 41 is connected to the support frame 1, and the conveying assembly 42 and the return assembly 43 are spaced apart and located above the return assembly 43. The first placement tray 22 or the second placement tray can be transported from the placement unit 2 to the surface detection unit 3 through the conveying assembly 42, and at the same time, the first placement tray 22 or the second placement tray can be transported from the surface detection unit 3 to the placement unit 2 through the return assembly 43, thereby realizing the reciprocating motion of the first placement tray 22 or the second placement tray.

[0036] Furthermore, the conveying assembly 42 includes a conveying baffle 421 and a plurality of conveying rollers 422.

[0039] Furthermore, the support block 222 is made of PU resin, and the support block 222 has a support groove 2221, and the bottom of the door workpiece is located in the support groove 2221. The support groove 2221 is provided to ensure the stability and reliability of the door workpiece when it is placed. The support block 222 is made of PU resin, which has high elasticity, wear resistance and good tear resistance, and will not damage the door workpiece.

[0040] Specifically, the boosting assembly 23 includes a boosting cylinder and a boosting rod 231. The base of the boosting cylinder is connected to the support frame 1, one end of the boosting rod 231 is connected to the telescopic rod of the boosting cylinder, and the other end of the boosting rod 231 is connected to the tray frame 221.

[0041] In this embodiment, the transport device for vehicle door inspection further includes a magnetic attraction component disposed on the support frame 1, which can be attracted to the first placement tray 22 or the second placement tray to ensure the stability and reliability of the first placement tray 22 or the second placement tray.

[0042] Optionally, the transport device for vehicle door inspection further includes an in-place detection device capable of detecting whether the first placement tray 22 or the second placement tray is placed at a designated position.

[0043] Optionally, the transport device for door inspection further comprises a clamping cylinder and a clamping plate, wherein the clamping cylinder is disposed on the support frame 1, and the clamping cylinder and the clamping plate are drivingly connected to drive the clamping plate to clamp the first placement tray 22 or the second placement tray.

[0044] In this embodiment, the surface detection assembly 32 includes a flip cylinder 321 and a detection support 322. The base of the flip cylinder 321 is mounted on the support frame 1, and the flip cylinder 321 and the detection support 322 are drivingly connected to drive the detection support 322 to rotate, and the detection support 322 can support the door workpiece. The detection support 322 has a support leg, and the support leg can support the door workpiece to drive the door workpiece to rotate through the flip cylinder 321.

[0045] The present embodiment also provides a method for transporting a door workpiece, which is applied to the transport device for door inspection in the above-mentioned scheme, including: placing the door workpiece on a first placement tray 22; using a booster assembly 23 of the transport device for door inspection to push the first placement tray 22 to the transport part 4; using the transport part 4 to transport the first placement tray 22 to the surface detection part 3, and the second lifting platform 31 drives the second placement tray to descend, so as to transport the second placement tray to the placement part 2 through the transport part 4; using the detection support 322 of the surface detection part 3 to support the door workpiece, and driving the detection support 322 to rotate by the flip cylinder 321 of the surface detection assembly 32, so that the staff can perform surface inspection.

[0046] The working steps of the present invention are as follows:

[0047] Removal of car door workpieces: When the placement part is in the original position and the robot is grabbing the workpiece, the placement part opening is in a placeable state, and the manipulator places the car door workpiece on the first placement tray. To prevent the car door workpiece from deforming, a support block made of adhesive is provided on the first placement tray. At the same time, to prevent the car door workpiece from rushing forward during transportation and to ensure the stability of the car door workpiece on the first placement tray, a limit baffle is provided on the side of the first placement tray.

[0048] Car door workpiece transportation: Car door workpieces in the placement section are inspected in place, the flip cylinder is in the flip state, the inspection table of the surface detection section is in the non-rotating state, the second lifting platform of the surface detection section descends, and the slide is in the lower layer; the operator activates the pneumatic button, the magnetic suction piece is in the non-magnetic state, the clamping cylinder is opened, the booster cylinder advances to the front end, and pushes the first placement tray to move forward with the car door workpiece on the upper slide. Due to the action of gravity, the car door workpiece slides toward the transportation section on the first placement tray. At this time, the slide of the surface detection section rises to the upper layer and docks with the upper slide of the transportation section. The first placement tray enters the slide of the surface detection section, and the car door workpiece is transported to the surface detection section. When the car door workpiece moves to the surface detection section, the first lifting platform descends, the booster cylinder returns, the flip cylinder flips, the placement section slide docks with the lower slide of the transportation section, the lower motor rotates, and drives the second placement tray to the placement section. After the second placement tray is in place, the electromagnet has a magnetic state to attract the second placement tray and fix it. The first lifting platform lifts the upper layer that drives the second placement tray to rise, the clamping cylinder clamps, and the outlet enters the next original position state.

[0049] Surface inspection section: After the door workpiece is transported to the surface inspection section, the operator triggers the pneumatic button. To prevent the surface inspection component from interfering with the pallet during rotation, the second lift table descends, and the lower edge of the door falls onto the support leg of the surface inspection component. The flip cylinder flips it. Due to the low speed of the cylinder, the door workpiece flips to an angle parallel to the ground without being fixed, which is convenient for operators to inspect the surface quality. After the second lift table descends to the lower level, it docks with the lower slide of the transportation section, and the motor rotates to move the first placement pallet to the transportation section, waiting to be transported to the placement section.

[0050] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
