Description

Technical Field

[0001] This utility model relates to the field of PCB manufacturing technology, and in particular to a tray-type board receiving machine. Background Technology

[0002] PCB boards are placed into trays upon arrival. The PCB boards need to be removed from the trays to proceed to the next process. Tray-type board take-up machines mainly rely on a six-axis robotic arm to move the trays. The suction cup assembly is connected to the six-axis robotic arm, and the position and angle of the suction cup assembly are adjusted through the multi-degree-of-freedom rotation of the six-axis robotic arm, allowing the suction cup assembly to reach various workstations for tray take-up and take-up. Existing board take-up machines use a six-axis robotic arm to place the boards into the trays and stack them on transport vehicles for transport. When the transport vehicle is full, it needs to be changed, requiring a work stoppage while waiting for the replacement. This results in poor production continuity and fails to meet usage requirements. Utility Model Content

[0003] The purpose of this utility model is to provide a Tray-type board receiving machine, which aims to solve the technical problem that existing technologies can only stop operation and wait for a change of transport vehicle, resulting in poor production continuity and inability to meet usage requirements.

[0004] To achieve the above objectives, this utility model provides a tray-type board receiving machine, including a frame. One side of the frame has a feeding section for inputting boards, and the other side has two parking positions. Each parking position is used to park a vehicle with a detachable receiving platform. One receiving platform is used to hold an empty tray stack, and the other receiving platform is used to hold a tray stack containing boards. A six-axis robot arm is also provided within the frame for placing boards into empty trays on one receiving platform and placing trays containing boards onto the other receiving platform. Each parking position has a lifting assembly for lifting the two receiving platforms. A temporary storage mechanism is provided at the top of each parking position for temporarily storing trays.

[0005] Preferably, the temporary storage mechanism includes at least two symmetrically arranged connecting rods and at least two sets of horizontal drive members disposed on the connecting rods. Each horizontal drive member has a fork connected to its output shaft for lifting the tray and separating it from the receiving platform.

[0006] Preferably, the connecting rod is further provided with a first pushing member, and the output shaft of the pushing member is provided with a first push plate.

[0007] Preferably, a second pusher is symmetrically arranged on the top of the parking space, and a second pusher plate is provided on the output shaft of the second pusher. The first pusher plate and the second pusher plate are distributed around the top of the parking space.

[0008] Preferably, a plurality of fixing brackets are provided at the edge of the top surface of the vehicle, and each fixing bracket is used to fix the four corners of the tray.

[0009] Preferably, the parking space is provided with limiting mechanisms on both sides of its bottom for fixing the vehicle.

[0010] Preferably, the feeding section includes a mounting frame, a lifting drive component and several pins disposed on the mounting frame, a support plate disposed on the output shaft of the lifting drive component, and anti-slip blocks disposed on the top of the several pins.

[0011] Preferably, a CCD camera is provided above the feeding section.

[0012] Preferably, the six-axis robotic arm is provided with a first suction cup group and a second suction cup group. The first suction cup group is used to adsorb the edge of the plate, and the second suction cup group is arranged around the first suction cup group and is used to adsorb the tray.

[0013] The Tray-type board receiving machine provided in this embodiment of the utility model has at least one of the following technical effects:

[0014] In operation, prepare two vehicles. Place several empty trays on the receiving platform of one vehicle to form an empty tray stack, and push it into the parking position on the feeding side. The receiving platform of the other vehicle is left empty and is pushed into the parking position on the receiving side. Two lifting components lift the receiving platforms of both vehicles to a higher height. Plates are fed through the feeding section. A six-axis robot in the frame places the plates from the feeding section into the empty trays. The six-axis robot then places the trays containing the plates into another receiving platform. The corresponding lifting component on one side raises the empty tray stack, while the lifting component on the other side lowers the corresponding receiving platform carrying the trays. This process is repeated until all empty trays are loaded. The originally empty support platform is now fully loaded with trays containing sheet metal. During this process, when the empty trays in the parking station on the feeding side are about to be fully loaded, the remaining trays are lifted by the corresponding temporary storage mechanism. The receiving platform on the feeding side is lowered by the lifting component and placed into the corresponding vehicle. The vehicle is then moved away, and a new vehicle loaded with empty trays is pushed into the parking station on the feeding side. The temporary storage mechanism allows time for vehicle replacement. When the receiving platform in the parking station on the receiving side is full, the corresponding temporary storage mechanism is activated. The six-axis robot places the trays containing sheet metal into the temporary storage mechanism, allowing time for vehicle replacement, improving production continuity and efficiency.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0028] In one embodiment of this utility model, such as Figs. 1-7As shown, a tray-type board receiving machine is provided, including a frame 1. A feeding section 2 is provided on one side of the frame 1 for inputting boards, and two parking stations 3 are provided on the other side. Each parking station 3 is used to park a vehicle 4 with a detachable receiving platform 41. One receiving platform 41 is used to hold a stack of empty trays, and the other receiving platform 41 is used to hold a stack of trays containing boards. A six-axis robot arm 11 is also provided in the frame 1 for placing boards into empty trays on one receiving platform 41 and placing trays containing boards onto the other receiving platform 41. Lifting components 30 are provided in both parking stations 3 to lift the two receiving platforms 41 respectively. A temporary storage mechanism 5 is provided at the top of each parking station 3 for temporarily storing trays.

[0029] Furthermore, the temporary storage mechanism 5 includes at least two symmetrically arranged connecting rods 51 and at least two sets of horizontal drive members 52 disposed on the connecting rods 51. Each horizontal drive member 52 has a fork 53 connected to its output shaft for lifting the tray and separating it from the receiving platform 41. The temporary storage mechanism 5 includes a first pusher 54 disposed on the connecting rods 51, with a first push plate 541 disposed on its output shaft. The temporary storage mechanism 5 also includes second pushers 55 symmetrically arranged on the top of the parking bay 3, with a second push plate 551 disposed on its output shaft. The first push plates 541 and the second push plates 551 are distributed around the top of the parking bay 3. Specifically, in use, two vehicles 4 are prepared. On one vehicle 4, the receiving platform 41 is filled with several empty trays to form an empty tray stack, which is then pushed into the parking position 3 on the feeding side. On the other vehicle 4, the receiving platform 41 is empty and is pushed into the parking position 3 on the receiving side. When the empty trays in the parking position 3 on the feeding side are almost fully loaded, the horizontal drive components 52 drive the corresponding forks 53 to move towards the opposite connecting rod 51 and lift the empty tray stack. The lifting assembly 30 lowers the receiving platform 41 on the feeding side and places it into the corresponding vehicle 4. The vehicle 4 is then removed, and a new vehicle 4 filled with empty tray stacks is pushed into the parking position 3 on the receiving side. In the parking station 3 on the feeding side, when the receiving platform 41 in the parking station 3 on the receiving side is fully loaded, the corresponding forks 53 are driven by the horizontal drive components 52 to move in the direction of the opposite connecting rod 51, so that the spacing between the forks 53 corresponds to the spacing of the trays. The six-axis robot arm 11 places the trays with plates, and the forks 53 cooperate to lift them, which allows time for changing vehicles 4 and improves production continuity. During operation, the first pusher 54 can drive the first push plate 541, and the second pusher 55 can drive the second push plate 551 to tidy up the four sides of the tray stack in the two parking stations 3, so as to maintain the stacking stability of the tray stack.

[0030] Furthermore, several fixing frames 411 are provided at the edge of the top surface of the vehicle 4, each fixing frame 411 being used to fix the four corners of the tray. Specifically, the lifting assembly 30 is used to lift the receiving platform 41. In the parking station 3 located on the feeding side, when the lifting assembly 30 drives the receiving platform 41 loaded with empty trays to rise, the four corners of the empty trays are limited by the fixing frames 411 to keep them vertically rising, preventing the empty trays from collapsing. In the parking station 3 located on the receiving side, the lifting assembly 30 first drives the receiving platform 41 to move upward and receive the trays input by the six-axis robot arm 11. Then, the lifting assembly 30 lowers the receiving platform 41 in height as the trays are placed one by one, and the first push... The four sides of the tray stack are adjusted and positioned by the plate 541 and the second push plate 551. During the descent, the tray stack enters between each fixed frame 411 and is fixed at the four corners by each fixed frame 411 to achieve a guiding effect. It is worth noting that the lifting component 30 can be a screw lifting mechanism to achieve precise height adjustment. At the same time, a photoelectric sensor can be set above the parking station 3 to sense and detect the top surface of the tray, thereby controlling the height adjustment of the receiving platform 41 by the screw lifting mechanism. A deceleration photoelectric sensor can also be set to adjust the speed of the screw lifting mechanism when adjusting the height of the receiving platform 41.

[0031] Furthermore, the parking space 3 is provided with limiting mechanisms 31 on both sides of its bottom for fixing the vehicle 4. Specifically, the limiting mechanism 31 can be a cylinder and a positioning rod. The cylinder pushes the positioning rod to move perpendicular to the side of the vehicle 4. At the same time, positioning holes that cooperate with the positioning rod are provided on both sides of the vehicle 4, and the positioning rod is inserted into the positioning holes to achieve the positioning function.

[0032] Furthermore, the feeding section 2 includes a mounting frame 21, a lifting drive 22 mounted on the mounting frame 21, and several pins 23. A support plate 221 is mounted on the output shaft of the lifting drive 22, and anti-slip blocks 231 are provided on the top of each pin 23. A CCD camera 24 is located above the feeding section 2. Specifically, when a board is input into the feeding section 2 by an external robotic arm, the lifting drive 22 raises the support plate 221, allowing the anti-slip blocks 231 on the top of each pin 23 to support the input board. Then, the lifting drive 22 lowers the support plate 221, at which point the anti-slip blocks 231 on each pin 23 support the bottom of the input board. The CCD camera 24 then identifies the board, thus achieving the function of board input and identification.

[0033] Furthermore, the six-axis robot arm 11 is equipped with a first suction cup assembly 12 and a second suction cup assembly 13. The first suction cup assembly 12 is used to adsorb the edge of the board, and the second suction cup assembly 13 is arranged around the first suction cup assembly 12 and is used to adsorb the tray. Specifically, when the six-axis robot arm 11 grips the board, the suction cups on the first suction cup assembly 12 adsorb the edge of the board in the feeding section 2 and place it into an empty tray in the parking station 3 located on the feeding side. At the same time, the second suction cup assembly 13 is activated, and the suction cups on the second suction cup assembly 13 adsorb the edge of the tray and place the tray onto the receiving platform 41 in the parking station 3 located on the receiving side, thus achieving the receiving effect.

[0034] Working principle: In use, prepare two vehicles 4. Place several empty trays on the receiving platform 41 of one vehicle 4 to form an empty tray stack, and push it into the parking station 3 on the feeding side. The receiving platform 41 of the other vehicle 4 is empty and is pushed into the parking station 3 on the receiving side. Two lifting components 30 respectively stack the receiving platforms 41 of the two vehicles 4 to raise their height. The plates are input through the feeding section 2. The six-axis robot 11 in the frame 1 puts the plates on the feeding section 2 into the empty trays. The six-axis robot 11 puts the trays containing the plates into the other receiving platform 41. The lifting component 30 on the corresponding side raises the empty tray stack, and the lifting component 30 on the other side lowers the corresponding receiving platform 41 carrying the trays. This process is repeated until all empty trays are stacked. Once all trays are loaded, the previously empty support platform becomes fully loaded with trays containing the panels. During this process, when the empty trays in the parking station 3 on the feeding side are about to be fully loaded, the remaining trays are lifted by the corresponding temporary storage mechanism 5. The receiving platform 41 for feeding is lowered by the lifting component 30 and placed in the corresponding vehicle 4. The vehicle 4 is then moved away, and a new vehicle 4 loaded with empty trays is pushed into the parking station 3 on the feeding side. The temporary storage mechanism 5 allows time for changing vehicles 4. When the receiving platform 41 in the parking station 3 on the receiving side is fully loaded, the corresponding temporary storage mechanism 5 is activated. The six-axis robot 11 places the trays containing the panels into the temporary storage mechanism 5, allowing time for changing vehicles 4, improving production continuity and efficiency.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
