[0002] Currently, in the PCB production process, the boards are stored in the material box. When loading the machine, there are pushing mechanisms and feeding mechanisms on both sides of the material box in the direction of board movement. First, the pushing mechanism needs to push the board to the feeding mechanism before the feeding mechanism can send the board out of the material box.

[0003] Throughout the feeding process, the material plate is pushed from the pushing mechanism to the feeding mechanism, and then the feeding mechanism sends the material box out. This process involves many actions, which reduces the feeding efficiency and increases the equipment cost and maintenance complexity. Utility Model Content

[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 3 As shown, an embodiment of the present invention provides a conveying mechanism 20, including a first driving member 23, a second driving member 24, a connecting member 21, and a conveying assembly 22. The first driving member 23 is connected to the connecting member 21, and the conveying assembly 22 is installed on the connecting member 21. The first driving member 23 can drive the connecting member 21 to reciprocate along a first direction a, thereby driving the conveying assembly 22 installed on the connecting member 21 to reciprocate along the first direction a, so that the conveying assembly 22 can abut against or detach from the material plate.

[0038] The second driving component 24 is connected to the conveying assembly 22. When the conveying assembly 22 comes into contact with the material plate, due to the contact and friction between the conveying assembly 22 and the material plate, the second driving component 24 can drive the conveying assembly 22 to move, thereby moving the material plate along the second direction b, thus realizing the conveying of the material plate. The first direction a and the second direction b intersect. When the material plate is not needed, the conveying assembly 22 disengages from the material plate and no longer contacts the material plate.

[0039] In this embodiment, the first driving member 23 controls the movement of the connecting member 21 in the first direction a, so that the conveying assembly 22 can abut against the material plate. Then, when the second driving member 24 drives the conveying assembly 22 to move, the material plate is moved. With the cooperation of the first driving member 23 and the second driving member 24, the conveying assembly 22 can directly abut against the material plate and drive it to move, without the need for additional devices to connect the conveying assembly 22, reducing the time loss that may be caused by intermediate transition links, thereby improving the feeding efficiency.

[0040] Wherein, the first direction a is perpendicular to the second direction b, the first direction a is the Z direction, and the second direction b is the X direction.

[0041] Specifically, in the field of PCB processing, in the second direction b, the conveying mechanism 20 is located between the material box 11 and the processing table, and the material board can be transferred between the material box 11 and the processing table through the conveying mechanism 20.

[0042] When the material plate in the material bin 11 is sent to the processing table, the first drive member 23 drives the conveying assembly 22 to abut against the portion of the material plate protruding from the material bin 11. Then, the second drive member 24 drives the conveying assembly 22 to move, thereby moving the material plate along the second direction b toward the processing table and sending the material plate to the processing table. The motion mechanism on the processing table can further move the material plate to adjust its position. After the material plate on the processing table is processed, the motion mechanism on the processing table sends the material plate toward the conveying mechanism 20. After the first drive member 23 drives the conveying assembly 22 to abut against the material plate, the second drive member 24 drives the conveying assembly 22 to move, thereby sending the material plate back to the material bin 11 along the second direction b, so that the material plate is stored in the material bin 11.

[0043] The conveying mechanism 20 enables bidirectional transfer of the material plate between the material box 11 and the processing machine table, simplifying the process.

[0044] In one embodiment, such as Figure 1 , Figure 2 As shown, connector 21 includes two sub-connectors 211, and conveying assembly 22 includes two conveyors 221. Both conveyors 221 are disposed between the two sub-connectors 211, and each conveyor 221 is mounted on a corresponding sub-connector 211. The first drive member 23 can drive at least one of the two sub-connectors 211 to move along a first direction a, so that the two conveyors 221 can clamp or release the material plate.

[0045] When the first driving member 23 is working, it can drive at least one of the two sub-connectors 211 to move along the first direction a. Since the two conveyors 221 are respectively mounted on the corresponding sub-connectors 211, the movement of the sub-connectors 211 will drive the conveyors 221 to move synchronously. When the two sub-connectors 211 move closer to each other, the two conveyors 221 also move closer to each other, thereby clamping the material plate; when the two sub-connectors 211 move away from each other, the two conveyors 221 also move away from each other, thereby releasing the material plate.

[0046] By controlling the movement of the two sub-connectors 211 in the first direction a, the two conveyors 221 can clamp the material plate, ensuring the stability of the material plate during the conveying process along the second direction b, and preventing the material plate from shifting or slipping during the conveying process.

[0047] In one embodiment, the first driving member 23 is used to drive the two sub-connecting members 211 to move towards each other or away from each other in the first direction a. The two sub-connecting members 211 move synchronously, so that the two conveying members 221 can move towards each other or away from each other. In this way, when clamping the material plate, the two conveying members 221 contact the material plate at the same time, and the force applied to the material plate is more uniform, which can better ensure the stability of the material plate in the clamping state.

[0048] Alternatively, the first driving member 23 can drive one of the sub-connectors 211 to move along a first direction a, while the other sub-connector 211 is fixed relative to the first driving member 23. Under the driving action of the first driving member 23, the sub-connector 211 connected to the first driving member 23 drives its corresponding conveyor 221 to move closer to or away from the conveyor 221 on the other sub-connector 211, thereby achieving the clamping and releasing of the material plate.

[0049] In one embodiment, such as Figure 1 , Figure 2 As shown, the first driving component 23 includes two first sub-driving components 231, and the connecting component 21 includes two sub-connecting components 211. The output ends of the two first sub-driving components 231 are respectively connected to each sub-connecting component 211. The first sub-driving component 231 is used to drive the corresponding sub-connecting component 211 to move along the first direction a, so that the two sub-connecting components 211 move towards each other or away from each other in the first direction a, thereby enabling the two conveying components 221 to clamp or release the material plate. By independently controlling the movement of the two sub-connecting components 211 by the two first sub-driving components 231, the sub-connecting components 211 can respond quickly, which helps to achieve faster movement of the sub-connecting components 211 and more efficient clamping and releasing operations of the material plate.

[0050] When the material plate needs to be clamped, the two first sub-drive members 231 are activated simultaneously, pushing the connected sub-connectors 211 to move towards each other along the first direction a. The two sub-connectors 211 move in opposite directions along the first direction a, thus achieving either facing or back-to-back movement of the two sub-connectors 211. Since the conveyor 221 is mounted on the sub-connectors 211, the facing movement of the two sub-connectors 211 will cause the two conveyors 221 to move closer synchronously until they contact and clamp the material plate, and then convey the material plate under the action of the second drive member 24. The back-to-back movement of the two sub-connectors 211 will cause the two conveyors 221 to move away synchronously, causing them to release the material plate.

[0051] The first sub-drive component 231 is a motor, and the output end of the motor is connected to the sub-connector 211.

[0052] In an alternative embodiment, the first driving member 23 includes a motor and a lead screw. The threaded section of the lead screw includes a first threaded section and a second threaded section, with opposite directions of rotation. The first threaded section and the second threaded section are each connected to a sub-connector 211. By providing first and second threaded sections with different directions of rotation on the lead screw, when the motor drives the lead screw to rotate, the two sub-connectors 211 can move towards each other or away from each other in the first direction a.

[0053] In one embodiment, such as Figure 1 , Figure 2 As shown, the second driving component 24 includes two second sub-driving components 241. The output ends of the two second sub-driving components 241 are respectively connected to each conveyor component 221. The second sub-driving components 241 are used to drive the corresponding conveyor component 221 to move, so that the two conveyor components 221 drive the clamped material plate to move along the second direction b. The two sub-connecting components 211 move towards each other, clamping the material plate between the two conveyor components 221. Then, the two second sub-driving components 241 start simultaneously, so that the two conveyor components 221 keep the conveying synchronously, thereby ensuring that the material plate can move smoothly along the second direction b in the clamped state without tilting or deflection. Moreover, by conveying simultaneously through the two conveyor components 221, the material plate has a higher conveying speed, which helps to improve the rhythm and efficiency of the entire production process.

[0054] The second sub-drive component 241 is a motor.

[0055] In one embodiment, such as Figure 2 , Figure 3As shown, the conveyor 221 includes a mounting frame 2211, a drive shaft 2212, and multiple sub-conveyors 2213. The mounting frame 2211 is connected to the sub-connector 211, thus connecting the conveyor 221 to the sub-connector 211. The sub-conveyors 2213 are mounted on the mounting frame 2211, and the multiple sub-conveyors 2213 are interconnected via the drive shaft 2212, which is connected to the output end of the second drive unit 24. When the second drive unit 24 starts, its output power is first transmitted to the drive shaft 2212. Since the multiple sub-conveyors 2213 are interconnected via the drive shaft 2212, the drive shaft 2212 transmits power from the second drive unit 24 to each sub-conveyor 2213, thereby driving the multiple sub-conveyors 2213 to move synchronously, thus ensuring the stability of the material plate during the conveying process.

[0056] Multiple sub-conveying components 2213 jointly convey the material plate, keeping the material plate stable during the conveying process, reducing the tilting or deformation of the material plate caused by uneven gravity, improving the stability of the conveying, and being able to adapt to the conveying needs of material plates of different sizes and shapes.

[0057] In one specific embodiment, the second driving member 24 includes two second sub-driving members 241. The output end of each second sub-driving member 241 is connected to the rotation shaft of the corresponding conveyor 221. The second sub-driving member 241 can drive the transmission shaft 2212 to rotate, thereby driving multiple sub-conveying members 2213 to move synchronously.

[0058] The number of sub-conveyors 2213 can be determined according to the size of the material plate. Taking two sub-conveyors 2213 as an example, the drive shaft 2212 passes through the mounting frame 2211 and protrudes from the mounting frame 2211 at both ends. The drive wheel 22131 of one sub-conveyor 2213 is installed at one end of the drive shaft 2212, and the drive wheel 22131 of the other sub-conveyor 2213 is installed at the other end of the drive shaft 2212.

[0059] In one embodiment, such as Figure 3 As shown, the sub-conveyor 2213 includes a drive wheel 22131, a belt 22132, and at least one driven wheel 22133. The drive wheel 22131 is mounted on the drive shaft 2212, and the driven wheel 22133 is mounted on the mounting bracket 2211. The belt 22132 is wound around the drive wheel 22131 and all the driven wheels 22133. The drive wheels 22131 of the multiple sub-conveyors 2213 are all mounted on the drive shaft 2212, and the drive wheels 22131 of the multiple sub-conveyors 2213 are spaced apart. The second drive member 24 can drive the drive shaft 2212 to rotate, thereby driving the multiple drive wheels 22131 to rotate, and thereby driving the belts 22132 of the multiple sub-conveyors 2213 to move.

[0060] In each conveying assembly 22, the belts 22132 of the two conveying members 221 move in opposite directions. When the two conveying members 221 clamp the material plate, the two belts 22132 directly contact the material plate, and the two belts 22132 apply a force in the same direction to the material plate, thereby driving the material plate to move along the second direction b.

[0061] As an example, such as Figure 1 , Figure 2 As shown, the first direction 'a' is the Z direction, and the second direction 'b' is the X direction. Connector 21 includes two sub-connectors 211, which are referred to as "upper sub-connector" and "lower sub-connector" for ease of description. The second drive unit 24 includes two second sub-drive units 241, which are referred to as "upper second sub-drive unit" and "lower second sub-drive unit" for ease of description. The conveying assembly 22 includes two conveying units 221, which are referred to as "upper conveyor" and "lower conveyor" for ease of description.

[0062] The upper conveyor is mounted on the upper sub-connector, and the lower conveyor is mounted on the lower sub-connector. The upper and lower sub-connectors move vertically. When the upper and lower sub-connectors move toward each other, the material plate is clamped between the upper and lower conveyors. When the upper and lower sub-connectors move away from each other, the upper and lower conveyors release the material plate.

[0063] The output end of the upper second sub-drive unit is connected to the drive shaft 2212 of the upper conveyor. The upper second sub-drive unit can drive the drive shaft 2212 of the upper conveyor to rotate, thereby driving the belts 22132 of the multiple sub-conveyors 2213 of the upper conveyor to move synchronously. The output end of the lower second sub-drive unit is connected to the drive shaft 2212 of the lower conveyor. The lower second sub-drive unit can drive the drive shaft 2212 of the lower conveyor to rotate, thereby driving the belts 22132 of the multiple sub-conveyors 2213 of the lower conveyor to move synchronously.

[0064] The movement direction of the belt 22132 of the upper conveyor is opposite to that of the belt 22132 of the lower conveyor. That is, when the belt 22132 of the upper conveyor moves clockwise, the belt 22132 of the lower conveyor moves counterclockwise. This allows the upper and lower belts to work together to move the material plate along the second direction b.

[0065] In one specific embodiment, such as Figure 3As shown, two driven wheels 22133 are provided, mounted on opposite sides of the mounting frame 2211 along the second direction b. The driving wheel 22131 is located between the two driven wheels 22133 along the second direction b. The belt 22132 is wound around the driving wheel 22131 and the two driven wheels 22133. The second sub-drive member 241 drives the transmission shaft 2212 to rotate, which in turn drives the driving wheel 22131 to rotate, thereby driving the belt 22132 to move. Preferably, the mounting frame 2211 is also provided with a tensioning wheel, which is located between the driving wheel 22131 and one of the driven wheels 22133, and can tension the belt 22132.

[0066] In one embodiment, such as Figure 2 As shown, the conveying assembly 22 also includes a buffer 222. The buffer 222 is connected between the mounting bracket 2211 of one of the conveyors 221 and the corresponding sub-connector 211. The buffer 222 is used to buffer when the conveyor 221 comes into contact with the material plate. At the moment when the conveyor 221 contacts the material plate, the buffer 222 can reduce the collision between the conveyor 221 and the material plate, and reduce the possibility of cracks, scratches or other damage to the surface of the material plate caused by excessive impact force.

[0067] The buffer 222 can be connected between the mounting frame 2211 of the upper conveyor and the upper sub-connector, or the buffer 222 can be connected between the mounting frame 2211 of the lower conveyor and the lower sub-connector, so as to ensure that the clamping force of the two conveyors 221 on the material plate is buffered at the same time, thereby reducing damage to the material plate.

[0068] In one embodiment, such as Figure 3 As shown, the buffer 222 includes a guide shaft 2221, a sliding sleeve 2222, and an elastic element. The sliding sleeve 2222 is connected to the sub-connector 211, and the guide shaft 2221 is connected to the mounting bracket 2211. The sliding sleeve 2222 is sleeved on the outside of the guide shaft 2221, and the elastic element is disposed between the outer circumferential surface of the guide shaft 2221 and the inner circumferential surface of the sliding sleeve 2222. The elastic element can undergo elastic deformation. When the conveyor 221 abuts against the material plate, the reaction force on the mounting bracket 2211 of the conveyor 221 is transmitted to the elastic element through the guide shaft 2221, causing the elastic element to deform and thus playing a buffering role.

[0069] The combination of guide shaft 2221 and sliding sleeve 2222 provides a stable support structure for the elastic element, enabling the elastic element to function accurately in the first direction a during the buffering process, avoiding the dispersion of buffering force and deviation of buffering direction.

[0070] The elastic element is a spring.

[0071] In one embodiment, such as Figure 1As shown, multiple conveying components 22 are provided, and these components are spaced apart along a third direction c on the connector 21, with the first direction, the second direction, and the third direction intersecting in pairs. When transferring material plates between the material box 11 and the processing machine, multiple material plates can be conveyed to the processing machine through the multiple conveying components 22. When the processing machine has a multi-spindle structure, multiple material plates can be processed simultaneously, further improving the feeding efficiency.

[0072] In this configuration, when multiple conveying components 22 are driven, each conveying component 22 can be driven independently. In this case, multiple second driving elements 24 are provided, each second driving element 24 driving the movement of its corresponding conveying component 22. Each second driving element 24 can independently drive its corresponding conveying component 22. When a certain conveying component 22 needs to be driven, the corresponding second driving element 24 is activated, transmitting power to multiple sub-conveying components 2213 within that conveying component 22 via transmission components such as the drive shaft 2212, thereby conveying the material plate. Depending on the different requirements of the processing machine, the independent driving method can effectively meet its needs, improving the flexibility and adaptability of the entire conveying mechanism 20.

[0073] Alternatively, multiple conveying components 22 can be driven together. In this case, the multiple conveying components 22 are connected by a transmission mechanism, and the second drive component 24 is used to drive the multiple conveying components 22 to move simultaneously. The multiple conveying components 22 are interconnected through a specific transmission mechanism. After the second drive component 24 is activated, it transmits power to one of the conveying components 22, and then transmits the power to the other conveying components 22 in sequence through the transmission mechanism, so that the multiple conveying components 22 move simultaneously. This ensures that the movement of the multiple conveying components 22 has a certain degree of synchronization, enabling them to work in coordination when conveying the material plate and maintain the same conveying speed and direction of movement.

[0074] When multiple conveying components 22 are connected by a drive, the drive shafts 2212 of two adjacent conveying components 22 can be connected by a connecting shaft and a coupling.

[0075] Preferably, the first direction, the second direction, and the third direction are perpendicular to each other, and the third direction is the Y direction.

[0076] As an example, multiple second drive members 24 are provided, each second drive member 24 including two second sub-drive members 241, and multiple conveying assemblies 22 are provided, each conveying assembly 22 including two conveying members 221. The multiple conveying assemblies 22 and multiple second drive members 24 are arranged in a one-to-one correspondence, the output end of the upper second sub-drive member is connected to the drive shaft 2212 of the upper conveying member, and the output end of the lower second sub-drive member is connected to the drive shaft 2212 of the lower conveying member.

[0077] As an example, one second drive unit 24 is provided, and each second drive unit 24 includes two second sub-drive units 241. Multiple conveying assemblies 22 are provided, and each conveying assembly 22 includes two conveying members 221. In this case, the drive shafts 2212 of all upper conveying members are connected to each other via couplings and connecting shafts, and the drive shafts 2212 of all lower conveying members are connected to each other via couplings and connecting shafts. The output end of the upper second sub-drive unit is connected to the drive shaft 2212 of one of the upper conveying members, and through the coupling and connecting shaft, it drives all the drive shafts 2212 of the upper conveying members to rotate together. The output end of the lower second sub-drive unit is connected to the drive shaft 2212 of one of the lower conveying members, and through the coupling and connecting shaft, it drives all the drive shafts 2212 of the lower conveying members to rotate together.

[0078] In one embodiment, such as Figure 1 , Figure 2 As shown, the conveying mechanism 20 also includes a bracket 25 and a third driving member 26. The connecting member 21 and the first driving member 23 are mounted on the bracket 25. The third driving member 26 can drive the bracket 25 to move along the second direction b, thereby moving the connecting member 21 and the conveying assembly 22 along the second direction b. When conveying a material plate between the material box 11 and the processing table, the conveying mechanism 20, through the third driving member 26, drives the conveying assembly 22 to move along the second direction b, adjusting the position of the conveying assembly 22 between the material box 11 and the processing table. When the material plate needs to be conveyed to the processing table, the third driving member 26 drives the conveying assembly 22 towards the material box 11 so that the conveying assembly 22 can contact the material plate. When the processing table unloads material and needs to store the material plate in the material box 11, the third driving member 26 drives the conveying assembly 22 towards the processing table so that the conveying assembly 22 can contact the material plate.

[0079] In one embodiment, such as Figure 2 As shown, the bracket 25 includes two support plates 251, and the connector 21 is located between the two support plates 251. The two ends of each sub-connector 211 can be slidably connected to the two support plates 251 respectively. Under the drive of the first driving member 23, the sub-connector 211 can slide relative to the two support plates 251.

[0080] There are two third driving components 26. The two third driving components 26 are connected to the two support plates 251 in a one-to-one correspondence. The two third driving components 26 drive together to ensure the stability of the connecting component 21 in the second direction b.

[0081] In one embodiment, two first driving members 23 are provided, and the two first driving members 23 are respectively mounted on two support plates 251. Each first driving member 23 includes two first sub-driving members 231. The two ends of the upper sub-connector are connected to the first sub-driving members 231, and the two ends of the lower sub-connector are connected to the first sub-driving members 231, thereby ensuring the stability of the two sub-connectors 211 in the vertical direction.

[0082] On the other hand, such as Figure 4 As shown, this embodiment of the present invention provides a loading and unloading device, including a base 10, a material box 11, and a conveying mechanism 20 as described in the above embodiment. The material box 11 and the conveying mechanism 20 are mounted on the base 10. The conveying assembly 22 is used to drive the material plate into or out of the material box 11. Through the cooperation of the first driving member 23 and the second driving member 24, the conveying assembly 22 can directly abut against the material plate and drive it to move, so that the material plate can enter or leave the material box 11. When the material plate leaves the material box 11, it can dock with other equipment to realize loading. During unloading, the material plate is stored in the material box 11 by the conveying assembly 22.

[0083] In one embodiment, the loading and unloading device further includes an automated transport vehicle 30, on which the base 10 is disposed. The automated transport vehicle 30 can move the base 10, thereby moving the material box 11 so that the material box 11 can dock with other equipment.

[0084] Furthermore, this embodiment of the invention provides a PCB processing equipment, including a processing table and the loading / unloading device described in the above embodiment. The conveying component 22 can move the material board between the processing table and the material box 11. The automatic transport vehicle 30 moves the material box 11, allowing it to dock with the processing table. The conveying component 22 transports the material board from the material box 11 to the processing table, enabling the processing table to process the material board. After processing, the conveying component 22 returns the material board to the material box 11.

[0085] In one embodiment, the processing machine is a multi-axis drilling machine. The material plate is transferred bidirectionally between the material box 11 and the multi-axis drilling machine through the conveying component 22. Multiple conveying components 22 are provided, and multiple conveying components 22 can load and unload materials from the multi-axis drilling machine at the same time, which has higher production efficiency.

[0086] 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.
