Description

Technical Field

[0001] The invention relates to the technical field, in particular to a DBC ceramic substrate post-processing horizontal line automatic material receiving device. Background Art

[0002] After the copper-clad ceramic substrate is sintered, the pattern will be transferred on the surface of the copper foil. Before the transfer, it needs to go through a post-processing horizontal line to clean the surface of the substrate. The current operation mode is to place the substrate on the horizontal conveyor roller. After the substrate is transmitted from the horizontal line, the personnel will take the product and put it on the plug-in board rack. When grabbing the substrate, it must be taken from the edge and not too much force should be applied. When putting it down, it must be released after it touches the buffer pad under the plug-in board rack to avoid ceramic cracks. This manual operation of placing the substrate will not only increase the labor intensity of the staff, but also greatly test the patience of the staff. Most importantly, the risk of possible ceramic cracks cannot be controlled.

[0003] The prior art CN113543500A discloses a ceramic substrate collecting device for ceramic copper cladding, and the technical scheme discloses "the present invention discloses a ceramic substrate collecting device for ceramic copper cladding in the technical field of ceramic substrate collecting device, comprising a conveyor frame and a receiving mechanism, wherein a U-shaped fixing frame is fixedly connected to the outer side of the conveyor frame; the present invention ensures that the ceramic substrate is stable by using a vertical feeding mechanism to receive the ceramic substrate each time the ceramic substrate is collected and each time the ceramic substrate is discharged from the copper cladding device, while driving the ceramic substrate to be vertically and slowly conveyed to the top of the receiving mechanism, so that the bottom surface of the ceramic substrate is almost in contact with the top of the receiving mechanism each time, and as the number of ceramic substrates increases, the distance between the receiving plate and the ceramic substrate is automatically adjusted, so that the ceramic substrates can be stacked stably, and when the receiving mechanism contacts the conveyor frame, the stacked ceramic substrates fall on the top of the conveyor frame, thereby avoiding damage to the ceramic substrates, and the stacked ceramic substrates are convenient for personnel to carry or perform other forms of quick operations".

[0004] Although the prior art has disclosed a ceramic substrate collection device for ceramic copper cladding, there are still some shortcomings. Specifically, in the actual production operation process, the collection device lacks a warpage detection device and cannot perform warpage detection on the ceramic substrate, resulting in defective products in the substrate. The collection device lacks an automatic unloading device and requires manual handling of the substrate, which poses a risk of ceramic cracks. Summary of the invention

[0030] The warpage detection device 11 includes a T-shaped plate 1101, which is fixed to the upper end surface of the lower chassis 1 and is located between the first mounting plate 401 and the second mounting plate 407. Two displacement sensors 1102 are installed on the T-shaped plate 1101, and the two displacement sensors 1102 are located on both sides of the upper end surface of the T-shaped plate 1101. The two displacement sensors 1102 are used to detect the warpage degree of the ceramic substrate.

[0031] Two manipulators 6 are fixed on the upper end surface of the lower chassis 1, and an elastic suction nozzle 7 is installed at the execution end of the manipulator 6, and an NG material box 8 is fixed on the upper end surface of the lower chassis 1. The elastic suction nozzle 7 facilitates the manipulator 6 to transport the ceramic substrate more firmly.

[0032] The elastic suction nozzle 7 includes a sleeve 701, a protrusion is provided on one side of the sleeve 701, the sleeve 701 is fixed to the execution end of the manipulator 6, a piston cylinder 702 is installed inside the sleeve 701, protrusions are provided on both sides of the piston cylinder 702, the sleeve 701 is slidably connected with the piston cylinder 702, the cylinder body of the piston cylinder 702 is sleeved with a spring 703, a suction cup 704 is installed at one end of the piston cylinder 702, and the elastic suction nozzle 7 is connected to an external negative pressure pump through a pipeline.

The protrusions provided on the piston cylinder 702 are used to discharge the air in the suction cup 704 when the suction cup 704 grabs the ceramic substrate, so that the suction cup 704 grabs more firmly.

[0033] A pressure sensor 12 is installed under the buffer plate 9. The displacement sensor 1102, the pressure sensor 12, the positioning camera 10 and the electronic display screen 13 are electrically connected to the control system. The pressure sensor 12 cooperates with the positioning camera 10 to accurately locate the position of the ceramic substrate on the buffer plate 9.

[0034] The working principle of the present invention is as follows: during the working process, the staff puts the empty feed frame 403 onto the conveyor belt 1 405 on the right feeding circulation line 4, the control system controls the motor 1 to operate to drive the pulley 1 404 to rotate, the conveyor belt 1 405 rotates to drive the feed frame 403 to move toward the side of the manipulator 6, the positioning camera 10 detects that one end of the feed frame 403 contacts the conveyor belt 2 409, the control system controls the motor 2 to operate, the motor 2 operates to drive the pulley 2 408 to rotate, the conveyor belt 2 409 rotates to drive the feed frame 403 to move to the conveyor belt 2 409, the motor 1 and the motor 2 are turned off, and the conveyor belt 1 405 and the conveyor belt 2 409 stop rotating.

[0035] The ceramic substrate is transported from an external horizontal conveyor belt to the buffer plate 9, and the pressure sensor 12 detects the change in pressure on the buffer plate 9. The control system controls the positioning camera 10 to perform preliminary positioning on the ceramic substrate. According to the notch of the ceramic piece on the ceramic substrate, it determines whether the robot 6 needs to drive the ceramic substrate to rotate 180° (the direction of the product must remain consistent when receiving the material. If the direction of the incoming material is inconsistent, adjustments must be made when receiving the material). The pressure sensor 12 cooperates with the positioning camera 10 to determine the specific position of the ceramic substrate on the buffer plate 9. The control system controls the operation of the robot 6. The execution end of the robot 6 drives the elastic suction nozzle 7 to be close to the ceramic substrate. One end of the sleeve 701 squeezes one end of the piston cylinder 702. The raised structure on the piston cylinder 702 squeezes the suction cup 704. The air inside the suction cup 704 is squeezed out. The external negative pressure pump extracts the air inside the elastic suction nozzle 7, so that the elastic suction nozzle 7 can fix the ceramic substrate. 6 execution end drives the ceramic substrate to move toward the T-plate 1101, and the rotation of the execution end of the manipulator 6 drives the ceramic substrate to rotate, so that the plane of the ceramic substrate is opposite to the T-plate 1101, and the spring 703 pushes one end of the piston cylinder 702, and the piston cylinder 702 and the sleeve 701 are engaged with each other. The sleeve 701 and the piston cylinder 702 are rigid materials, so that the ceramic substrate does not deviate downward in a vertical state. The displacement sensor 1102 obtains the closest and farthest distances between the ceramic substrate and the displacement sensor 1102, and calculates the warpage according to the difference between the two distances. If the calculated warpage is too large, the control system controls the manipulator 6 to move the defective ceramic substrate into the NG material box 8, and the negative pressure pump pumps air into the elastic suction nozzle 7 to make the ceramic substrate fall into the NG material box 8. If the calculated warpage is qualified, the manipulator 6 puts the ceramic substrate into the feed frame 403, and repeats the above feeding process until the feed frame 403 is full.

[0036] When the two feeding frames 403 on the support plate 1 406 are full, the control system cylinder 412 starts to operate to drive the piston rod 411 to move downward, the piston rod 411 drives the piston plate 410 to move downward, the piston plate 410 drives the support plate 1 406 to move downward, and the two feeding frames 403 move downward under the drive of the support plate 1 406. When the positioning camera 10 detects that the support plate 1 406 and the support plate 2 414 are at the same height, the cylinder 412 stops operating, the motor 2 and the motor 3 start operating, and the feeding frames 40 3 moves from the conveyor belt 2 409 to the conveyor belt 3 417, the cylinder 412 operates, pushing the piston rod 411 to move upward, driving the support plate 1 406 to move upward to the initial position, the motor 1 and the motor 2 operate, the conveyor belt 1 405 and the conveyor belt 2 409 drive the feed frame 403 to move to the conveyor belt 2 409, the conveyor belt 3 417 transports the feed frame 403 to the receiving area, and then the feed frame 403 is taken down manually, and the working process of the left feeding circulation line 5 is the same as the working process of the right feeding circulation line 4.

[0037] When the equipment fails, the control system controls the robot 6 to place the ceramic substrate on the horizontal conveyor belt onto the buffer plate 9, and the staff can open the cabinet door 3 to take out the feed frame 403 in the receiving area.

[0038] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
