Description

Technical Field

[0001] This utility model belongs to the field of PCB transfer technology, and in particular relates to a delivery device and PCB processing equipment. Background Technology

[0002] When the current delivery equipment transfers PCBs, the boards are stored in a bin. The lifting mechanism can move the bin up and down, so that the drive mechanism on the delivery equipment can correspond to each layer in the bin. This allows one drive mechanism to control the receiving and releasing of boards from several layers of the entire bin.

[0003] When the delivery device is connected to other equipment, the installation height of the drive mechanism on the delivery device is fixed, which may limit the number of layers of material plates that can be stacked in the bin, thus failing to achieve the maximum storage capacity and reducing the delivery efficiency of the delivery device.

[0036] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0037] like Figures 1 to 6 As shown, an embodiment of the present invention provides a delivery device including a movable base 1, a connecting part 2, a drive mechanism 3, a lifting mechanism 4, a material box 6, a laser sensor 13, and a material box bracket 5. The connecting part 2 is installed on the movable base 1, and the lifting mechanism 4 and the drive mechanism 3 are installed on the connecting part 2. The lifting mechanism 4 can drive the material box bracket 5 and the material box 6 placed on the material box bracket 5 to move up and down, so that the drive mechanism 3 can drive the material plate in the material box 6 to move.

[0038] The material box 6 has multiple layers along the vertical direction, and each layer is filled with material plates. When the lifting mechanism 4 drives the material box bracket 5 to move up and down, the material box 6 moves up and down with the material box bracket 5, so that the drive mechanism 3 can connect with the material plates of each layer. The drive mechanism 3 drives the material plates to move, thereby realizing the purpose of the material plates of each layer entering and leaving the material box 6.

[0039] The movable base 1 has a recessed portion, in which at least a portion of the material box bracket 5 can be accommodated in the vertical direction. By providing the recessed portion on the movable base 1, when the lifting mechanism 4 moves the material box bracket 5 downward, the material box bracket 5 can reach its maximum lowering amount. With the height of the drive mechanism 3 remaining unchanged, the distance between the material box bracket 5 and the drive mechanism 3 increases, thereby increasing the number of layers and storage capacity of the material box 6, maximizing the conveying capacity of the delivery device, and improving the overall conveying efficiency.

[0040] In one embodiment, a laser sensor 13 is mounted on the movable base 1. The laser sensor 13 is used to detect the position of the material plate when the drive mechanism 3 drives the material plate to move, and to determine whether the material plate has entered or left the material box 6. It can monitor the positional changes of the material plate under the action of the drive mechanism 3 in real time. Compared with the existing case where the sensor is mounted on the connecting part, the laser sensor 13 in this embodiment expands the detection coverage.

[0041] The laser sensor 13 is located on the side of the movable base 1 near the inlet / outlet of the material bin 6. During plate collection, when a plate enters any layer of the material bin 6, the laser sensor 13 can detect it. As the plate gradually enters the material bin 6, when the laser sensor 13 can no longer detect it, it indicates that the plate has completely entered the material bin 6. During plate delivery, when a plate is delivered from any layer of the material bin 6, the laser sensor 13 can detect it. When the laser sensor 13 can no longer detect it, it indicates that the plate has completely exited the material bin 6.

[0042] In one embodiment, the mobile base 1 is an AGV (Automated Guided Vehicle).

[0043] In one embodiment, the lifting mechanism 4 includes a motor, a lead screw, and a lead screw nut. The motor is mounted on the connecting part 2, and the output end of the motor is connected to the lead screw. The lead screw nut is threadedly connected to the lead screw and is mounted on the material box bracket 5. The motor drives the lead screw to rotate, which can be converted into linear motion of the lead screw nut, thereby driving the material box bracket 5 to move up and down.

[0044] In one embodiment, the movable base 1 includes a movable main body, a first traveling wheel, and a second traveling wheel. The first traveling wheel and the second traveling wheel are spaced apart on the movable main body in a first direction a. The first direction a is perpendicular to the vertical direction and is a longitudinal direction. The recessed portion is located between the first traveling wheel and the second traveling wheel, which allows the material box bracket 5 to be lowered to the maximum extent without increasing the vertical space requirement of the material box bracket 5, and can increase the number of layers and storage capacity of the material boxes 6 on the material box bracket 5.

[0045] In one embodiment, such as Figure 2 As shown, the mobile body is provided with a first wheel cover 11 and a second wheel cover 12. The first wheel cover 11 is used to cover the first wheel and protect it, and the second wheel cover 12 is used to cover the second wheel and protect it.

[0046] The first travel wheel cover 11 and the second travel wheel cover 12 protrude vertically from the upper surface of the moving body, and a recess is formed between the first travel wheel cover 11 and the second travel wheel cover 12. The space between the first travel wheel cover 11 and the second travel wheel cover 12 defines the shape and size of the recess, so that the recess can accommodate the material box bracket 5.

[0047] In one embodiment, such as Figure 3 As shown, the connecting part 2 is equipped with an electrical control box 21 and an operation panel 22. The electrical control box 21 can control the movement of the first and second traveling wheels, and the operation panel 22 can display the operating status information of the equipment.

[0048] In one embodiment, such as Figure 2 As shown, the vertical dimension of the material box bracket 5 is larger than the vertical dimension of the recess. Since the recess is defined by the first travel wheel cover 11 and the second travel wheel cover 12, the vertical dimension of the recess is equal to the vertical dimension of the first travel wheel cover 11 protruding from the moving body. The first travel wheel cover 11 and the second travel wheel cover 12 are at the same height in the vertical direction, meaning the material box bracket 5 is higher than the first travel wheel cover 11 and the second travel wheel cover 12. When the material box bracket 5 is accommodated in the recess, there is a gap between the material box 6 on the material box bracket 5 and the first travel wheel cover 11 and the second travel wheel cover 12, preventing the weight of the material box 6 from directly acting on the first travel wheel cover 11 and the second travel wheel cover 12 and causing deformation, thus avoiding affecting the normal rotation of the first and second travel wheels.

[0049] The difference between the vertical dimension of the material box bracket 5 and the vertical dimension of the recess is determined according to the load-bearing capacity of the material box bracket 5. By setting the difference in the vertical dimension, a safe deformation distance is left to prevent the material box bracket 5 from being squeezed and deformed by the material box 6, and the material box 6 from directly pressing on the first travel wheel cover 11 and the second travel wheel cover 12.

[0050] Preferably, the difference between the vertical dimension of the material box bracket 5 and the vertical dimension of the recess is less than 3mm.

[0051] In one embodiment, such as Figure 2 As shown, the connecting part 2 is disposed at one end of the movable base 1 along the second direction b, which is perpendicular to the vertical direction. Specifically, the first direction a and the second direction b are perpendicular to each other with respect to the vertical direction, and the second direction b is horizontal.

[0052] The dimension of the material box bracket 5 in the second direction b is smaller than the dimension of the movable base 1 in the second direction b, so that the material box bracket 5 does not protrude from the movable base 1 in the second direction b, thereby reducing the collision between the material box 6 and other equipment during the process of the movable base 1 driving the material box 6 to move.

[0053] The delivery device usually needs to move between various devices. Since the material box bracket 5 does not protrude from the moving base 1 in the second direction b, when the moving base 1 moves the material box 6, the material box 6 maintains a sufficient safe distance from the surrounding devices. It will not collide with other devices due to the protrusion of the material box bracket 5, which greatly reduces the possibility of the material box 6 colliding with the surrounding devices during the movement and reduces the impact of the material plate on the external collision.

[0054] In one embodiment, such as Figure 2 As shown, the delivery device also includes a counterweight 14, which is installed at the other end of the mobile base 1 along the second direction b. The counterweight 14 can effectively adjust the center of gravity of the mobile base 1, making it closer to the center of the wheels or within the support range of the wheels, preventing the delivery device from tipping over and ensuring the safe transportation of materials.

[0055] In one embodiment, such as Figure 2 As shown, a limiting member 55 is provided at the end of the material box bracket 5 away from the connecting part 2. The limiting member 55 is used to limit the position of the material box 6 on the material box bracket 5 in the second direction b, so that the material box 6 can be accurately placed when placed on the material box bracket 5. During the movement of the delivery device, the limiting member 55 limits the position of the material box 6 in the second direction b, which can effectively prevent the material box 6 from sliding or deviating on the material box bracket 5 along the second direction b, and ensure the stability of the material box 6 during transportation.

[0056] Preferably, at least two limiting members 55 are provided, and all the limiting members 55 are spaced apart at the end of the material box bracket 5 away from the connecting part 2 to ensure the limiting effect on the material box 6.

[0057] In one embodiment, such as Figure 2 As shown, the material box bracket 5 includes a first connecting frame 51, a second connecting frame 52, and at least one reinforcing member 53. The first connecting frame 51 is slidably connected to the connecting part 2 and connected to the lifting mechanism 4. The second connecting frame 52 is connected to the first connecting frame 51 and is used to support the material box 6. The lifting mechanism 4 can drive the first connecting part 2 to slide relative to the connecting part 2 in the vertical direction, thereby driving the second connecting frame 52 to move up and down in the vertical direction.

[0058] The second connecting frame 52 can be accommodated in the recess, and the vertical dimension of the second connecting frame 52 is larger than the vertical dimension of the recess.

[0059] The reinforcing member 53 is disposed on the first connecting frame 51 and connected to the second connecting frame 52, which can increase the connection strength between the first connecting frame 51 and the second connecting frame 52. The reinforcing member 53 can increase the load-bearing capacity of the material box bracket 5 and limit the swing of the material box bracket 5.

[0060] In one embodiment, such as Figure 2 , Figure 5 As shown, a positioning block 621 is provided on the material box 6, and a positioning pin 54 is provided on the second connecting frame. The positioning pin 54 is used to engage with the positioning block 621, providing a precise positioning method for the installation of the material box 6 on the material box bracket 5. When placing the material box 6, simply align the hole on the positioning block 621 with the positioning pin 54 and insert it to ensure that the material box 6 is in the correct position. At the same time, during the movement of the delivery device, the cooperation between the positioning pin 54 and the positioning block 621 can effectively prevent the material box 6 from shifting on the material box bracket 5, enhancing the stability of the material box 6 during operation.

[0061] In one embodiment, such as Figure 4 As shown, the drive mechanism 3 includes a support base 31, a paddle drive 32, and a paddle block 33. The support base 31 is installed on the connecting part 2. The output end of the paddle drive 32 is connected to the paddle block 33. The paddle drive 32 can drive the paddle block 33 to rotate.

[0062] The material box 6 is equipped with a power receiver 622 and a conveying mechanism 611. A toggle block 33 is connected to the power receiver 622 via a drive mechanism. The toggle drive 32 drives the power receiver 622 to rotate via the toggle block 33, causing the conveying mechanism 611 to move the sheet metal. The toggle block 33 serves as an intermediate transmission component connecting the toggle drive 32 and the power receiver 622. The power output from the toggle drive 32 is transmitted to the power receiver 622 via the toggle block 33, causing the power receiver 622 to rotate. The rotation of the power receiver 622 further drives the conveying mechanism 611 within the material box 6. The conveying mechanism 611, according to its structural form (such as a synchronous belt or chain), applies a corresponding force to the sheet metal, thereby moving the sheet metal within the material box 6.

[0063] Among them, the paddle drive component 32 is a motor.

[0064] In one embodiment, such as Figure 4 As shown, the drive mechanism 3 also includes a fixed plate 34, a connecting plate 35, and a push drive member 36. The push drive member 36 is installed above the support base 31, the fixed plate 34 is installed on the support base 31, the paddle drive member 32 is installed on the connecting plate 35, the connecting plate 35 is slidably connected to the fixed plate 34, the output end of the push drive member 36 is connected to the connecting plate 35, and the push drive member 36 can drive the connecting plate 35 to move relative to the fixed plate 34, thereby driving the paddle drive member 32 to move so that the paddle block 33 moves closer to or further away from the power receiver 622.

[0065] During the process of the material plate entering and exiting the material box 6, when it is necessary to drive the material plate to move, the drive component 36 is pushed to drive the paddle drive component 32 to move, so that the actuating block 33 approaches the power receiver 622 and establishes a reliable transmission connection with it. This ensures that the power output by the paddle drive component 32 can be smoothly transmitted to the power receiver 622 through the actuating block 33, and then drive the material plate to move through the conveying mechanism 611 in the material box 6. When it is not necessary to drive the material plate to move, pushing the drive component 36 can also drive the actuating block 33 away from the power receiver 622, avoiding unnecessary contact and friction between the two, preventing component wear and possible mis-transmission.

[0066] The output end of the drive component 36 is connected to the connecting plate 35 via a connecting block 37, so that the drive component 36 can drive the connecting plate 35 to move.

[0067] In one embodiment, such as Figure 5 , Figure 6 As shown, the material box 6 includes a frame 62 and multiple support frames 61, which are spaced apart vertically. Each support frame 61 can hold a material plate. A positioning block 621 is provided on the frame 62.

[0068] Multiple power receiving units 622 and multiple conveying mechanisms 611 are provided. The number of power receiving units 622 and the number of support frames 61 are the same. The power receiving units 622 are mounted on the frame 62, and the multiple conveying mechanisms 611 are mounted one-to-one on the multiple support frames 61. When the lifting mechanism 4 moves the material box up and down, the conveying mechanism 611 of each support frame 61 can be connected to the actuating block 33 through the corresponding power receiving unit 622.

[0069] When a material plate needs to be moved into or out of the material box 6, the lifting mechanism 4 moves the material box 6 up and down in the vertical direction, allowing the drive mechanism 3 to connect with the conveying mechanism 611 on the support frame 61 of that layer. This pushes the drive component 36 to drive the actuating block 33 closer to the power receiver 622. After the actuating block 33 engages with the power receiver 622, the actuating drive component 32 drives the actuating block 33 to rotate, causing the power receiver 622 to start rotating. The rotation of the power receiver 622 further drives the conveying mechanism 611 to work, thereby moving the material plate and achieving the purpose of the material plate moving into or out of the material box 6.

[0070] On the other hand, this embodiment of the invention provides a PCB processing equipment, including a processing machine 6 and a delivery device as described in the above embodiment. The material box 6 is placed on a material box bracket 5, and the movable base 1 can drive the material box 6 to move, so that the material box 6 and the processing machine can exchange materials, ensuring the accuracy of the material board transfer between the two. The processing machine can obtain the material board to be processed from the material box 6, and after processing, accurately put the material board back into the material box 6 or transfer it to the material box 6 of the next process.

[0071] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
