[0041] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0042] Accompanying Figure 1-10 The radiator automatic feeding device for aluminum anodic oxidation surface treatment described in the present invention includes a feeding conveyor line 1, a material distribution unit 2, an arrangement unit 3, a handling manipulator 4, a jig 5, a jig conveyor line 6, and a jig on-line inspection station 7;

[0043] The feeding conveyor line 1 is used to receive the aluminum radiators 8 and send the aluminum radiators 8 to the material distribution unit 2;

[0044] The material distribution unit 2 is used to send the aluminum radiators 8 conveyed on the feeding conveyor line 1 to the arrangement unit 3 one by one;

[0045] The arrangement unit 3 is used to arrange multiple aluminum radiators 8 in a straight line at intervals;

[0046] The jig 5 has a planar frame structure, and at least one surface is provided with a claw assembly 51 arranged in a matrix for hanging the aluminum radiators 8;

[0047] The jig conveyor line 6 is used to transport the jig 5 to the jig on-line inspection station 7;

[0048] The jig on-line inspection station 7 includes a jig positioning mechanism 71 and a jig inspection mechanism 72 respectively located on both sides of the jig conveyor line 6. The jig positioning mechanism 71 is used to fix the jig 5 on the jig conveyor line 6, and the jig inspection mechanism 72 is used to inspect the positioned jig 5, specifically to detect whether there are any remaining aluminum radiators 8 on several claw assemblies 51 that have not been removed and whether the claw assemblies 51 are damaged;

[0049] The handling manipulator 4 is used to simultaneously grab multiple aluminum radiators 8 from the arrangement unit 3 and hang them on multiple claw assemblies 51 of the jig 5, including a robotic arm 41 and a claw assembly 42 arranged at the driving end of the robotic arm 41;

[0050] During operation: The feeding conveyor line 1 continuously sends the aluminum radiators 8 to the material distribution unit 2. Through the material distribution unit 2, the aluminum radiators 8 are sent to the arranging unit 3 one by one. Then, the arranging unit 3 arranges multiple aluminum radiators 8 in a straight line at intervals. During this period, the fixture conveyor line 6 transports the fixture 5 to the in-line fixture inspection station 7. The fixture 5 is placed parallel to the conveying direction of the fixture conveyor line 6, and the side of the fixture 5 with the jaw assembly 51 faces the fixture inspection mechanism 72. When the fixture 5 reaches the in-line fixture inspection station 7, the fixture positioning mechanism 71 first fixes the fixture 5 on the fixture conveyor line 6, and then the fixture inspection mechanism 72 inspects the positioned fixture 5. Specifically, it inspects whether there are residual aluminum radiators 8 not removed on several jaw assemblies 51 and whether the jaw assemblies 51 are damaged. If it is detected that there is an aluminum radiator 8 on a certain jaw assembly 51, the corresponding station of the arranging unit 3 will not feed materials to avoid interference. If it is detected that the head of a certain elastic jaw 52 is damaged, since the aluminum radiator 8 cannot be suspended, the corresponding station of the arranging unit 3 will also not feed materials. When the inspection is completed, the robotic arm 41 drives the jaw assembly 42 to simultaneously grab multiple aluminum radiators 8 from the arranging unit 3 and hang them on the multiple jaw assemblies 51 of the fixture 5 until the fixture 5 is full of aluminum radiators 8. Finally, the fixture conveyor line 6 discharges the fixture 5 from the in-line fixture inspection station 7 for the automatic feeding of the next fixture 5.

[0051] Furthermore, the aluminum radiator 8 can be received by the manipulator placing the aluminum radiators 8 on the feeding conveyor line 1 one by one, or the feeding conveyor line 1 can be directly docked with the production line of the aluminum radiators 8, and the production line directly transports the aluminum radiators 8 to the feeding conveyor line 1 to achieve full-automatic docking, eliminating the processes of manual feeding, handling, and transferring, etc. This not only reduces the labor intensity but also improves the work efficiency.

[0052] Furthermore, as Figure 3-4 described, the material distribution unit 2 includes a material distribution platform 21 located between the feeding conveyor line 1 and the arranging unit 3, a material distribution position 22 arranged on the material distribution platform 21 and at the discharge end of the feeding conveyor line 1, a loading position 23 located on one side of the material distribution position 22, a material distribution cylinder 24 located on the other side of the material distribution position 22 for pushing the aluminum radiators 8 from the material distribution position 22 into the loading position 23 one by one, and a loading cylinder 25 arranged on the material distribution platform 21 for pushing the radiators from the loading position 23 into the arranging unit 3.

[0053] When the feeding conveyor line 1 transports the aluminum radiators 8 to the material distribution position 22, the material distribution cylinder 24 first pushes the aluminum radiators 8 from the material distribution position 22 into the loading position 23, and then the loading cylinder 25 pushes the radiators from the loading position 23 into the arranging unit 3 to achieve the material distribution function, ensuring that only one aluminum radiator 8 enters the arranging unit 3 at a time. It has the advantages of simple structure and low manufacturing cost.

[0054] Furthermore, as Figure 4As described above, limit plates 26 are provided at one end of the material distribution level 22 opposite to the discharge end of the feeding conveyor line 1 and at one end of the loading level 23 opposite to the material distribution cylinder 24, which play a limiting role when the feeding conveyor line 1 transports the aluminum radiator 8 to the material distribution level 22 and when the material distribution cylinder 24 pushes the aluminum radiator 8 from the material distribution level 22 to the loading level 23.

[0055] Further, as Figure 3 described above, the arranging unit 3 includes a linear module 31 placed horizontally and perpendicular to the loading cylinder 25, a carrying platform 32 horizontally arranged on the driving end of the linear module 31 and flush with the material distribution platform 21, and a plurality of dividing blocks 33 evenly spaced on the carrying platform 32 to form a plurality of positioning grooves 34.

[0056] During operation: The linear module 31 drives the carrying platform 32 to translate, so that the plurality of positioning grooves 34 are aligned with the loading level 23 one by one, and the radiator is pushed from the loading level 23 into the positioning groove 34 by the loading cylinder 25; If it is detected that there is an aluminum radiator 8 on a certain claw assembly 51, or if it is detected that the head of a certain elastic claw 52 is damaged, the corresponding positioning groove 34 skips the loading and remains in an empty state.

[0057] Further, as Figure 3 described above, chamfers are provided at one end of the plurality of dividing blocks 33 close to the material distribution unit 2, and positioning plates 35 are provided at one end away from the material distribution unit 2; During loading, the positioning plate 35 can play a positioning role for the aluminum radiator 8 in the positioning groove 34, and the design of the chamfer plays a guiding role to facilitate the aluminum radiator 8 to enter the positioning groove 34.

[0058] Further, as Figure 5 described above, each of the claw assemblies 51 includes two pairs of elastic claws 52 distributed up and down and symmetrically placed, and the elastic claws 52 are used to hang the aluminum radiator 8 by the outward-opening elastic force; In order to adapt to aluminum radiators 8 of different shapes, the existing fixture 5 adopts an elastic claw structure, and when loading, it is necessary to press the claw assembly 51 to make the heads of the elastic claws 52 approach each other in order to install the aluminum radiator 8.

[0059] As Figure 6 described above, the jaw assembly 42 includes a fixed seat 421, a movable seat 422 placed parallel to the fixed seat 421, a telescopic cylinder 423 provided on the fixed seat 421 for driving the movable seat 422 to approach or move away from the fixed seat 421, a plurality of guide posts 424 provided on the movable seat 422 and passing through the fixed seat 421, a plurality of jaw cylinders 425 provided on the movable seat 422 for simultaneously grasping a plurality of aluminum radiators 8, and an extrusion mechanism 426 provided on the fixed seat 421 and located on both sides of the plurality of jaw cylinders 425 for pressing the claw assembly 51 to make the heads of the elastic claws 52 approach each other.

[0060] When the mechanical arm 41 drives the clamping claw assembly 42 to simultaneously grab multiple aluminum radiators 8 from the arrangement unit 3, the multiple clamping claw cylinders 425 can directly respectively grab multiple aluminum radiators 8;

[0061] When the robot arm 41 drives the clamping claw assembly 42 to hang the multiple aluminum radiators 8 grabbed onto the multiple claw assemblies 51 of the fixture 5: first, the clamping claw assembly 51 is pressed by the extrusion mechanism 426 to make the heads of the elastic clamping claws 52 close to each other, and then the movable seat 422 is driven by the telescopic cylinder 423 to drive the multiple clamping claw cylinders 425 to extend, so that the heads of the elastic clamping claws 52 are located in the aluminum radiator 8, and then the extrusion mechanism 426 releases the clamping claw assembly 51, and the aluminum radiator 8 is suspended by the elastic force of the elastic clamping claws 52 opening outwards, and finally the multiple clamping claw cylinders 425 respectively release the multiple aluminum radiators 8, and at the same time the telescopic cylinder 423 drives the movable seat 422 to drive the multiple clamping claw cylinders 425 to retract to the initial position, completing the loading operation.

[0062] Further, if Figure 7 The extrusion mechanism 426 comprises a rotating shaft 4261 placed parallel to the movable seat 422, a plurality of V-shaped connecting rods 4262 rotatably arranged on the rotating shaft 4261 and staggered with the clamping cylinder 425, a connecting shaft 4263 for connecting the upper ends of the plurality of V-shaped connecting rods 4262, a pressing shaft 4264 for connecting the lower ends of the plurality of V-shaped connecting rods 4262, and an extrusion cylinder 4265 hingedly arranged on the side of the fixed seat 421 and having a driving end connected to the connecting shaft 4263; the distance from the clamping cylinder 425 to the fixed seat 421 is smaller than the distance from the pressing shaft 4264 to the fixed seat 421;

[0063] During operation: the connecting shaft 4263 is driven by the extrusion cylinder 4265 to drive the upper ends of the multiple V-shaped connecting rods 4262 to descend. Since the V-shaped connecting rods 4262 are rotatably set on the rotating shaft 4261, the lower ends of the multiple V-shaped connecting rods 4262 drive the pressing shaft 4264 to press the claw assembly 51 so that the heads of the elastic claws 52 are close to each other, which is convenient for completing the loading operation.

[0064] Further, if Figure 8 The jig positioning mechanism 71 includes a positioning frame 711, a position detection component 712 arranged on the positioning frame 711 for detecting whether the jig 5 has reached the detection position, and positioning components 713 respectively arranged on both sides of the positioning frame 711 for clamping the two sides of the jig 5; when working: first, the position detection component 712 is used to detect whether the jig 5 has reached the detection position. If the jig 5 has reached the detection position, the positioning components 713 on both sides are used to clamp the jig 5 to achieve positioning.

[0065] Further, if Figure 9As described above, the position detection component 712 includes a detection swing arm cylinder 7121 provided at the top of the positioning frame 711, a detection arm 7122 provided at the driving end of the detection swing arm cylinder 7121, and a sensor 7123 provided at the head of the detection arm 7122. Since the surface treatment of aluminum anodization is carried out, a hook is provided at the top of the jig 5. The detection arm 7122 is rotated by driving the detection swing arm cylinder 7121, and the sensor 7123 is used to sense the hook to determine whether the jig 5 reaches the detection position.

[0066] Further, as Figure 9 described above, the positioning component 713 includes a positioning swing arm cylinder 7131 provided on the side of the positioning frame 711, a clamping arm 7132 provided at the driving end of the positioning swing arm cylinder 7131, and a clamping block 7133 provided at the head of the clamping arm 7132. After the position detection component 712 detects that the jig 5 reaches the detection position, the two positioning components 713 simultaneously drive the clamping arms 7132 to rotate through the positioning swing arm cylinders 7131, and clamp both sides of the positioning frame 711 through the clamping blocks 7133 to achieve positioning.

[0067] Further, both the detection swing arm cylinder 7121 and the positioning swing arm cylinder 7131 are prior arts. For details, reference can be made to a metal drilling clamping fixture and a clamping cylinder disclosed in the prior art CN202222376601.5, so the structure thereof will not be introduced in detail.

[0068] Further, as Figure 9-10 described above, the jig detection mechanism 72 includes an X-axis linear module 721 placed in parallel with the jig conveying line 6, a Z-axis linear module 722 vertically provided at the driving end of the X-axis linear module 721, a Y-axis cylinder 723 horizontally and vertically provided on the Z-axis linear module 722 and pointing to one side of the jig positioning mechanism 71, and a detection head 725 provided at the driving end of the Y-axis cylinder 723. The detection head 725 includes a vertically placed mounting seat 7251, a first sensor 7252 provided on the mounting seat 7251 for detecting whether there is a residue of the aluminum radiator 8 on the claw assembly 51, and a plurality of second sensors 7253 provided on the mounting seat 7251 and corresponding to the number and positions of the elastic claws 52 for simultaneously detecting whether the heads of the elastic claws 52 are damaged.

[0069] During operation: First, the X-axis linear module 721 drives the detection head 725 to move to the side of the fixture 5 where the jaw assembly 51 is provided. Then, the Y-axis cylinder 723 drives the detection head 725 to extend and approach the jaw assembly 51 on the fixture 5. Then, the first sensor 7252 detects whether there is a residual aluminum radiator 8 on the jaw assembly 51, and at the same time, the second sensor 7253 detects whether the head of the elastic jaw 52 is damaged; when the detection is completed, the X-axis linear module 721 drives the detection head 725 back to the initial position, misaligning the detection head 725 with the fixture 5 to facilitate the loading of the handling robot 4; generally, the Z-axis linear module 722 only adjusts the height of the detection head 725 to correspond to the jaw assembly 51 on the fixture 5 when replacing fixtures 5 of different models.

[0070] Further, as Figure 9 described, the fixture detection mechanism 72 further includes a detection frame 724; the detection frame 724 is in a long strip shape or a frame structure, and a plurality of detection heads 725 are provided, arranged at intervals in a straight line on the long-strip-shaped detection frame 724, or distributed in a matrix on the frame-structured detection frame 724, capable of detecting multiple at a time, thereby improving the detection efficiency.

[0071] Further, the first sensor 7252 and the second sensor 7253 are optical sensors, such as fiber optic sensors.

[0072] The above are only specific application examples of the present invention and do not constitute any limitation to the protection scope of the present invention. Any technical solutions formed by equivalent transformation or equivalent substitution fall within the scope of the protection of the present invention.
