[0035] 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.

[0036] like Figures 1 to 6 As shown, an embodiment of the present invention provides a delivery device, including a conveying mechanism 1, a material plate driving mechanism 2, a first driving mechanism 3, and a material box 4. The conveying mechanism 1 plays the role of carrying and moving the material box 4, and can transport the entire delivery device and the material plate in the material box 4 to the vicinity of the transfer station, in preparation for the subsequent docking of the material box 4 and the transfer station.

[0037] The first drive mechanism 3 is mounted on the conveying mechanism 1. The material plate drive mechanism 2 includes a second drive mechanism 21, a mounting frame 22, and a material plate drive assembly 23. The material plate drive assembly 23 is mounted on the mounting frame 22. The output end of the second drive mechanism 21 is connected to the mounting frame 22. When the second drive mechanism 21 drives the mounting frame 22 to move, the material plate drive assembly 23 on the mounting frame 22 moves together. The material plate drive assembly 23 is used to drive the material plate in the material box 4 to move, so as to deliver or receive the material plate.

[0038] The first drive mechanism 3 can drive the material box 4 to reciprocate along the first direction a. The position of the material box 4 in the first direction a can be adjusted by the first drive mechanism 3, so that the material board drive assembly 23 can dock with the material boards of each layer in the material box 4, realizing the feeding and receiving of all material boards. The second drive mechanism 21 can drive the material board drive assembly 23 to reciprocate along the first direction a, so that the material box 4 can exchange material boards with the transfer table of the PCB processing equipment at a preset docking height.

[0039] In this embodiment, the material board driving assembly 23 is moved by the second driving mechanism 21, which can adjust the position of the material board driving assembly 23 in the first direction a. This allows the material board driving assembly 23 to stay at any position within the stroke range of the second driving mechanism 21 in the first direction a. When the material board driving assembly 23 drives the material board into and out of the material box 4, the material board can dock with transfer stations of different heights, so that the delivery device can better adapt to the layout of various PCB processing equipment.

[0040] In PCB processing equipment, when the PCB is exchanged between the material box 4 and the transfer table, if the transfer table cannot reach the preset docking height due to space layout limitations, the first drive mechanism 3 drives the material box 4 to move so that it is at the same docking height as the transfer table. Then, the second drive mechanism 21 drives the PCB drive assembly 23 to move to the same docking height as the transfer table. The PCB drive assembly 23 can deliver the PCB to the transfer table or receive the PCB delivered by the transfer table, so that the PCB can be smoothly transferred between the material box 4 and the transfer table, avoiding problems such as the PCB falling or colliding due to height differences, which would affect its quality and the continuity of the entire production process.

[0041] In one embodiment, the transport mechanism 1 is an AGV (Automated Guided Vehicle).

[0042] like Figure 4 As shown, the first direction 'a' is the vertical direction. The first drive mechanism 3 includes a motor, a lead screw 31, and a hopper bracket 32. The motor is mounted on the conveying mechanism 1, and its output end is connected to the lead screw 31. The lead screw 31 is threadedly connected to the hopper bracket 32, which is slidably connected to the conveying mechanism 1. The motor can drive the lead screw 31 to rotate, thereby moving the hopper bracket 32 ​​up and down. The hopper 4 is placed on the hopper bracket 32, and the hopper bracket 32 ​​moves the hopper 4 up and down under the drive of the motor. After the material plate drive assembly 23 moves to the docking height, the hopper 4 moves up and down under the drive of the first drive mechanism 3, so that each layer of material plate in the hopper 4 can dock with the transfer station. Under the drive of the material plate drive assembly 23, the material plate is sent out of the hopper 4 or received.

[0043] In one embodiment, the conveying mechanism 1 is provided with a first linear guide rail 11 and a second linear guide rail 12. The first linear guide rail 11 and the second linear guide rail 12 extend along a first direction a. The slider on the first linear guide rail 11 and the slider on the second linear guide rail 12 are both connected to the material box bracket 32, so that the material box bracket 32 ​​can move on the first linear guide rail 11 and the second linear guide rail 12 under the drive of the motor. This makes the material box bracket 32 ​​have good motion stability when moving in the first direction a, and can improve the load capacity of the material box bracket 32.

[0044] In other embodiments, the linear guide rails on the conveying mechanism 1 are not limited to the first linear guide rail 11 and the second linear guide rail 12, but can be set according to the size of the hopper bracket 32.

[0045] In one embodiment, a positioning block 411 is provided on the material box 4, and a positioning pin 321 is provided on the material box bracket 32. The positioning pin 321 can be inserted and engaged with the positioning block 411 to limit the placement position of the material box 4 on the material box bracket 32.

[0046] In one embodiment, the material plate driving assembly 23 is movably connected to the mounting frame 22 along the second direction b, wherein the first direction a and the second direction b intersect. The material box 4 and the material box bracket 32 ​​are limited by a positioning block 411 and a positioning pin 321. When the positioning block 411 is installed on the material box 4, there may be installation errors, causing the material plate in the material box 4 to not be driven by the material plate driving assembly 23. In this embodiment, through the adjustable connection structure between the material plate driving assembly 23 and the mounting frame 22, the position of the material plate driving assembly 23 along the second direction on the mounting frame 22 can be adjusted, ensuring that the material plate driving assembly 23 can accurately drive the material plate on the material box 4 after the material box 4 is placed on the material box bracket 32. Preferably, the first direction a and the second direction b are perpendicular, with the first direction a being vertical and the second direction b being horizontal.

[0047] In one embodiment, such as Figure 2 As shown, the mounting frame 22 includes a first plate 221, a second plate 222, and a third plate 223. The first plate 221 is connected to the output end of the second drive mechanism 21. The second plate 222 and the third plate 223 are arranged opposite to each other on the first plate 221 along a first direction, with the second plate 222 located above the third plate 223. The material plate drive assembly 23 is installed between the second plate 222 and the third plate 223. By arranging the second plate 222 and the third plate 223 opposite to each other on the first plate 221, a frame structure 41 is formed, providing a stable mounting space and support for the material plate drive assembly 23.

[0048] In one embodiment, such as Figure 2As shown, the mounting position of the material plate drive assembly 23 on the second plate 222 along the second direction b is adjustable, and the mounting position of the material plate drive assembly 23 on the third plate 223 along the second direction b is adjustable.

[0049] In this embodiment, the adjustable connection structure between the material plate drive assembly 23 and the second plate 222 and the third plate 223 allows the position of the material plate drive assembly 23 on the mounting frame 22 to be adjusted. After the material box 4 is placed on the material box bracket 32, it ensures that the material plate drive assembly 23 can be accurately connected to the material plate on the material box 4.

[0050] In one embodiment, such as Figure 2 As shown, the second plate 222 is provided with a first strip hole 2221, and the third plate 223 is provided with a second strip hole. The first strip hole 2221 and the second strip hole extend along the second direction, and the first strip hole 2221 and the second strip hole provide the material plate drive assembly 23 with a range of movement in the second direction b.

[0051] The material plate drive assembly 23 is connected to the second plate 222 on the side near the second plate 222 via a first connector. The position of the first connector in the first strip hole 2221 along the second direction b is adjustable, thereby adjusting the installation position of the material plate drive assembly 23 on the second plate 222.

[0052] The material plate drive assembly 23 is connected to the third plate 223 on the side near the third plate 223 via a second connector. The position of the second connector in the second strip hole along the second direction b is adjustable, thereby adjusting the installation position of the material plate drive assembly 23 on the third plate 223.

[0053] When the positioning block 411 on the material box 4 is installed, the position of the first connector in the first strip hole 2221 and the position of the second connector in the second strip hole can be adjusted to finely adjust the position of the material plate drive assembly 23 in the second direction b. That is, the distance between the output end of the material plate drive assembly 23 and the positioning pin 321 can be adjusted so that after the material box 4 is positioned on the material box bracket 32, the material plate drive assembly 23 can be accurately connected to the material plate drive, which can send the material plate out of the material box 4, or smoothly pull the material plate back into the material box 4 when receiving the material plate from the transfer table, thus improving the success rate and accuracy of material plate exchange.

[0054] Specifically, the first and second connecting parts can be in the form of bolts, pins, etc. Taking bolts as an example, the first connecting part is a first bolt, and the second connecting part is a second bolt. The first bolt passes through the first slot 2221 and connects to the upper side of the material plate drive assembly 23, and the second bolt passes through the second slot and connects to the lower side of the material plate drive assembly 23. When it is necessary to adjust the position of the material plate drive assembly 23, loosen the bolts, move the material plate drive assembly 23 to drive the first bolt to slide into the first slot 2221 to a suitable position, and drive the second bolt to slide into the second slot to a suitable position, and then tighten them to fix it. This connection method not only ensures the stability of the connection, but also facilitates the position adjustment operation, so that the material plate drive assembly 23 can change its relative position on the mounting bracket 22 according to actual needs.

[0055] In one embodiment, such as Figure 2 As shown, the material plate driving mechanism 2 also includes a first sensor 24, a second sensor 25, and a sensing plate 27. The sensing plate 27 is mounted on the first plate 221 of the mounting frame 22. The sensing plate 27 reciprocates along the first direction together with the mounting frame 22 under the drive of the second driving mechanism 21. The first sensor 24 and the second sensor 25 are spaced apart from each other along the first direction on the second driving mechanism 21. The first sensor 24 is located above the second sensor 25. The first sensor 24 and the second sensor 25 are used to sense the sensing plate 27 respectively, so as to limit the travel distance of the mounting frame 22 along the first direction.

[0056] The distance between the first sensor 24 and the second sensor 25 is the effective range of movement of the mounting frame 22 in the first direction. By reasonably setting their spacing, the movement stroke of the mounting frame 22 can be precisely controlled, thereby controlling the movement stroke of the material plate drive assembly 23 and avoiding the problem of the material plate drive assembly 23 colliding with other components due to exceeding the normal operating range.

[0057] In one embodiment, such as Figure 2 As shown, the material plate drive mechanism 2 also includes a third sensor 26, which is positioned between the first sensor 24 and the second sensor 25 in the first direction. The third sensor 26 senses the sensing plate 27 to determine the zero-point position of the mounting frame 22. By setting the zero-point position, accurate stroke control can be achieved when the mounting frame 22 moves up and down, ensuring the accuracy and repeatability of the operation.

[0058] In one embodiment, the material plate driving assembly 23 includes a support base 231, a paddle drive member 232, and a paddle block 233. A first connector passes through a first strip hole 2221 and is connected to the upper side of the support base 231, and a second connector passes through a second strip hole and is connected to the lower side of the support base 231. The support base 231 is mounted on a mounting bracket 22, and the output end of the paddle drive member 232 is connected to the paddle block 233, enabling the paddle drive member 232 to drive the paddle block 233 to rotate.

[0059] The material box 4 is equipped with a power receiver 412 and a conveying mechanism 421. The actuating block 233 can be driven to the power receiver 412. The actuating drive 232 can drive the power receiver 412 to rotate through the actuating block 233, so that the conveying mechanism 421 can move the sheet material. The position of the drive assembly in the second direction is adjusted by the first strip hole 2221 and the second strip hole, so that the actuating block 233 can be precisely driven to the power receiver 412 without misalignment, which facilitates the power receiver 412 to transmit power to the conveying mechanism 421.

[0060] The actuating block 233 serves as an intermediate transmission component connecting the paddle drive 232 and the power receiver 412. The power output from the paddle drive 232 is transmitted to the power receiver 412 through the actuating block 233, causing the power receiver 412 to start rotating. The rotation of the power receiver 412 further drives the conveying mechanism 421 inside the material box 4. The conveying mechanism 421 applies a corresponding force to the material plate according to its own structural form (such as a synchronous belt 4213, chain, etc.), thereby driving the material plate to move within the material box 4.

[0061] Among them, the paddle drive component 232 is a motor.

[0062] In one embodiment, such as Figure 3 As shown, the material plate driving assembly 23 also includes a fixed plate 234, a connecting plate 235, and a push drive 236. The push drive 236 is installed above the support base 231, the fixed plate 234 is installed on the support base 231, the paddle drive 232 is installed on the connecting plate 235, the connecting plate 235 is slidably connected to the fixed plate 234, the output end of the push drive 236 is connected to the connecting plate 235, and the push drive 236 can drive the connecting plate 235 to move relative to the fixed plate 234, thereby driving the paddle drive 232 to move, so that the paddle block 233 moves closer to or further away from the power receiver 412.

[0063] During the process of material bin 4 accurately docking with the transfer station and material plates entering and exiting material bin 4, when it is necessary to drive the material plate to move, the drive component 236 is pushed to drive the paddle drive component 232 to move, so that the actuating block 233 approaches the power receiver 412 and establishes a reliable transmission connection with it. This ensures that the power output by the paddle drive component 232 can be smoothly transmitted to the power receiver 412 through the actuating block 233, and then drive the material plate to move through the conveying mechanism 421 in the material bin 4. When it is not necessary to drive the material plate to move, the drive component 236 can also drive the actuating block 233 away from the power receiver 412, avoiding unnecessary contact and friction between the two, preventing component wear and possible mis-transmission.

[0064] The output end of the drive component 236 is connected to the connecting plate 235 via a connecting block 237, so that the drive component 236 can drive the connecting plate 235 to move.

[0065] In one embodiment, such as Figure 5 As shown, the material box 4 includes a frame 41 and multiple support frames 42, which are spaced apart along a first direction, and each support frame 42 can hold a material plate.

[0066] Multiple power receiving units 412 and multiple conveying mechanisms 421 are provided. The number of power receiving units 412 is the same as the number of support frames 42, and the number of conveying mechanisms 421 is the same as the number of support frames 42. The power receiving units 412 are installed on the frame 41, and the multiple conveying mechanisms 421 are installed one-to-one on the multiple support frames 42. The conveying mechanism 421 of each support frame 42 is connected to the toggle block 233 through the corresponding power receiving unit 412.

[0067] In the first direction, after the material box 4 is moved to a suitable docking position by the first driving mechanism, the driving component 236 drives the actuating block 233 to approach the power receiving component 412. After the actuating block 233 cooperates with the power receiving component 412, the actuating drive component 232 drives the actuating block 233 to rotate, causing the power receiving component 412 to start rotating. The rotation of the power receiving component 412 will further drive the conveying mechanism 421 to work, thereby driving the material plate on the support plate 423 to move.

[0068] In one embodiment, such as Figure 6 As shown, the support frame 42 is provided with a guide groove 424, and the pins on the material plate are located in the guide groove 424. When the material plate driving assembly 23 drives the material plate to move, the material plate can be guided by the guide groove 424.

[0069] In one embodiment, such as Figure 6As shown, the conveying mechanism 421 includes a drive wheel 4211, a driven wheel 4212, a timing belt 4213, and a connecting shaft 4214. The connecting shaft 4214 is connected to the power receiver 412. The drive wheel 4211 is mounted on the connecting shaft 4214, and the driven wheel 4212 is mounted on the support frame 42. The timing belt 4213 is wound around the drive wheel 4211 and the driven wheel 4212. When the paddle drive 232 drives the paddle block 233 to rotate, it can drive the power receiver 412 to rotate, thereby causing the connecting shaft 4214 to rotate. Under the action of the drive wheel 4211 and the timing belt 4213, the timing belt 4213 moves, thereby driving the material plate to move.

[0070] In one embodiment, such as Figure 6 As shown, the support frame 42 includes a frame body 425, a guide plate 422, and a support plate 423. One end of the support plate 423 is connected to the frame body 425, and the other end is connected to the frame 41. The guide plate 422 is mounted on the support plate 423 and is used to guide the material plate over the support plate 423 when the material box 4 moves to receive the material plate. The support plate 423 can share the weight of the material plate and enhance the overall stability of the support frame 42, reducing deformation of the support frame 42.

[0071] When the material plate enters the material box 4, the material plate may be deformed, causing it to get stuck at the position of the support plate 423. By setting the guide plate 422, the material plate can be guided so that it can pass smoothly over the support plate 423 and avoid getting stuck at the support plate 423.

[0072] The guide plate 422 includes a transition plate 4221 and an inclined plate 4222. The transition plate 4221 is mounted on the support plate 423. In the direction of material plate movement, one end of the inclined plate 4222 is connected to the transition plate 4221, and the other end of the inclined plate 4222 is a free end that slopes downwards. When encountering the material plate, the inclined plate 4222 uses its inclined surface to contact the material plate, guiding the material plate to move along this inclined surface. By changing the direction of material plate movement, the material plate can pass over the support plate 423 in a relatively gentle and smooth manner, avoiding direct rigid collision between the material plate and the support plate 423 or jamming due to inability to pass.

[0073] On the other hand, this utility model embodiment provides a PCB processing equipment, including a processing machine, a transfer station, and a delivery device as described in the above embodiment. The transfer station is located between the processing machine and the delivery device, and the transfer station and the material box 4 can exchange materials.

[0074] In one embodiment, the PCB processing equipment is a drilling machine.

[0075] The transfer table has a matching lifting base, which enables the transfer table to move up and down vertically. The transfer table has multiple layers, each layer with multiple workstations. The material plate drive assembly 23 moves the material plate, which can deliver the material plate in the material box 4 to the workstation on the transfer table, and then transfer it to the processing machine for processing. After processing, the material plate on the processing machine enters the transfer table and then enters the material box 4.

[0076] Taking a two-layer transfer station as an example, the first drive mechanism 3 drives the material box 4 to move upward, the lifting base drives the transfer station to move upward, the material plate drive assembly 23 docks with the power receiver 412 of the material box 4, and sequentially sends out the material plates of the upper layers of the material box 4, so that the first layer of the transfer station is filled with material plates. Then, the transfer station sends the material plates of the first layer to the processing machine table for processing.

[0077] During processing on the machining platform, the first drive mechanism 3 drives the material box 4 to continue moving upward, filling the first layer of the transfer platform with material plates. After the material plates on the machining platform are processed, the lifting base drives the transfer platform to move until the second layer of the transfer platform aligns with the machining platform, sending the processed material plates into the second layer of the transfer platform. Then, the transfer platform descends, sending the material plates from the first layer of the transfer platform onto the machining platform. The lifting base then drives the transfer platform to rise, causing the second layer of the transfer platform to align with the material box 4, transferring the processed material plates into the material box 4. During the docking process between the second layer of the transfer platform and the material box 4, as the second layer of the transfer platform rises, the first layer of the transfer platform also rises accordingly. Since the first layer of the transfer platform is higher than the second layer, the transfer platform may interfere with other components, preventing the second layer of the transfer platform from rising to the docking height with the material box 4. At this time, the second drive mechanism 21 drives the mounting frame 22 to descend, and the first drive mechanism 3 drives the material box 4 to descend, in order to make up for the height difference between the docking height of the second layer of the transfer platform and the material box 4, so that the material plate can be smoothly transferred between the material box 4 and the transfer platform.

[0078] The above description is only a preferred embodiment of the present utility model and is 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.
