[0039] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0040] like Figures 1 to 6 As shown, one embodiment of the present invention provides a temporary storage mechanism comprising a temporary storage rack 1, a lifting mechanism 3, and a conveyor assembly 2. The conveyor assembly 2 is disposed on one side of the temporary storage rack 1 and comprises a drive member 21 and a plurality of clamping jaws 22 connected to the output end of the drive member 21. The temporary storage rack 1 is provided with a plurality of guide portions in the height direction, each of which is provided with a plurality of first guide grooves 124 extending in a first direction. The clamping jaws 22 are used to clamp the sheet material.

[0041] The output end of the lifting mechanism 3 is connected to the conveying assembly 2. The lifting mechanism 3 can drive the conveying assembly 2 to move up and down so that the clamping claw portion 22 can be connected to the first guide groove 124 on each guide portion under the drive of the driving member 21. The lifting mechanism 3 can be a conventional cylinder or a motor. The output end of the lifting mechanism 3 can be directly connected to the conveying assembly 2 or indirectly connected to the conveying assembly 2.

[0042] The conveying assembly 2 is driven up and down by the lifting mechanism 3 to connect with guide parts of different heights. Multiple clamping parts 22 correspond one-to-one to multiple first guide grooves 124. The driving member 21 can drive each clamping part 22 to enter or leave the corresponding first guide groove 124. When the clamping part 22 enters the first guide groove 124, the clamping part 22 can move back and forth along the first guide groove 124 under the drive of the driving member 21 to send the material plate out or into the temporary storage rack 1. After the material plate is moved, the clamping part 22 leaves the first guide groove 124.

[0043] After the drilling machine completes processing on the PCB, the driver 21 drives each jaw 22 into its corresponding first guide slot 124. The jaw 22 moves along the first guide slot 124 toward the drilling machine. After the jaw 22 grips the PCB, the driver 21 drives the jaw 22 away from the drilling machine and places the PCB on the temporary storage rack 1. When the drilling machine needs to load the PCB, the jaw 22 enters the first guide slot 124 and grips the PCB. The driver 21 drives the jaw 22 toward the drilling machine, thereby moving the PCB out of the temporary storage rack 1 and into the drilling machine.

[0044] In this embodiment, the temporary storage mechanism is located between the drilling machine and the material box, and the temporary storage mechanism enables the connection between the drilling machine and the material box. Specifically, the PCB drilling machine has multiple processing spindles, each corresponding to a different processing station. After the materials at the multiple processing stations are processed, the temporary storage mechanism connects with the drilling machine, and the multiple clamping jaws 22 can be used to unload the processed materials and store them on the temporary storage rack 1. Then, through the connection between the temporary storage mechanism and the material box, the processed materials are gradually transferred to the material box. Alternatively, the material plates to be processed in the material box are sent to the temporary storage mechanism, and the temporary storage mechanism transports the material plates to be processed to the processing station of the drilling machine through multiple clamping claws 22, completing the exchange of the processed material plates and the material plates to be processed. During the exchange process, the conveying assembly is driven up and down by the lifting mechanism, and the clamping claws are docked with each guide part, so that the material plates can be temporarily stored on each guide part, so that the temporary storage of the material plates is achieved through the temporary storage mechanism, and the drilling machine can load and unload materials in time without stopping and waiting for the material box, avoiding the situation where the material box cannot receive the material plates in time or send the material plates to the drilling machine, which affects the processing efficiency of the drilling machine, saving production time and improving the processing efficiency of the drilling machine.

[0045] In one embodiment, if Figure 1 As shown, in the first direction, the material sheet has a first edge and a second edge that are relatively arranged, and the first edge is closer to the drilling machine than the second edge. When the material sheet is sent from the temporary storage rack 1 to the drilling machine, the clamping jaw portion 22 enters the first guide groove 124 until the clamping jaw portion 22 passes over the first edge and clamps the material sheet. The driving member 21 drives the clamping jaw portion 22 to move along the first guide groove 124 until it enters the drilling machine and overlaps the material sheet on the drilling machine. At this time, after the clamping jaw 223 releases the material sheet, the driving member 21 drives the clamping jaw portion 22 away from the drilling machine until the clamping jaw portion 22 moves to the second edge of the material sheet. After clamping the material sheet, the driving member 21 drives the clamping jaw portion 22 close to the drilling machine, and the clamping jaw portion 22 pushes the material sheet toward the drilling machine until the material sheet is in place and stops moving.

[0046] Similarly, when the material sheet is fed from the drilling machine to the temporary storage rack 1, the driving member 21 drives the clamping jaw 22 to approach the material sheet and clamp the second edge of the material sheet. The driving member 21 drives the clamping jaw 22 to return until a part of the material sheet enters the temporary storage rack 1. The clamping jaw 22 releases the material sheet, and the driving member 21 drives the clamping jaw 22 to move to the first edge of the material sheet. After re-clamping the material sheet, the driving member 21 drives the clamping jaw 22 away from the drilling machine. The clamping jaw 22 pushes the material sheet toward the temporary storage rack 1 until the material sheet completely enters the temporary storage rack 1.

[0047] In one embodiment, if Figure 2 As shown, the temporary storage rack 1 includes a frame 11, and a plurality of guide portions are spaced apart in the height direction of the frame 11. The guide portions include a plurality of connecting portions 12 and a plurality of supporting members 13. The plurality of connecting portions 12 are provided on the frame 11, and each supporting member 13 is mounted on a corresponding connecting portion 12. The supporting members 13 are used to place material sheets, and each connecting portion 12 is provided with a first guide groove 124.

[0048] Each guide portion is divided into multiple workstations by multiple connecting portions 12, each of which can store a sheet of material. The support member 13 on each connecting portion 12 supports the sheet of material. When the clamping jaw 22 moves along the first guide groove 124, it can push the sheet of material onto the support member 13 or push the sheet of material off the support member 13. The temporary storage rack 1 can store multiple sheets of material, which can meet the loading and unloading needs of the drilling machine.

[0049] In one embodiment, if Figure 2 As shown, the frame 11 comprises multiple layers of frames spaced apart along the height, with each guide portion positioned on a corresponding frame. This multi-layered structure allows for more sheet material to be placed on the temporary storage rack 1, ensuring uninterrupted loading and unloading during the drilling machine's operation. To facilitate the loading and unloading of sheets within each frame, the number of connecting portions 12 on each guide portion matches the number of clamping portions 22, meaning the total number of connecting portions 12 is at least twice the number of clamping portions 22.

[0050] To ensure work efficiency, the sheets to be processed can be placed on a portion of the racks, while the processed sheets can be placed on the remaining racks. For example, a two-layer rack is used. The two layers are the first rack and the second rack. The first rack holds multiple processed sheets, while the second rack holds multiple sheets to be processed. The multiple sheets to be processed on the second rack are fed into the drilling machine. During the drilling process, the temporary storage mechanism docks with the material box, feeding the processed sheets on the first rack into the material box. At the same time, the sheets to be processed in the material box are gradually fed into the vacated spaces on the second rack. After the drilling process is completed, the above exchange action is repeated until all sheets have been processed.

[0051] In one embodiment, if Figure 2 、 Figure 4 As shown, the connecting portion 12 includes a base plate 121, a first guide plate 122 and a second guide plate 123. The base plate 121 is mounted on the frame 11. The first guide plate 122 and the second guide plate 123 are spaced apart from the base plate 121. The first guide groove 124 is formed between the first guide plate 122 and the second guide plate 123.

[0052] Among them, the base plate 121 is installed on the frame 11, the first guide plate 122 and the second guide plate 123 extend along the first direction, the first guide groove 124 is U-shaped, and the distance between the first guide plate 122 and the second guide plate 123 is determined according to the width of the clamping claw part 22, so that the clamping claw part 22 is limited between the first guide plate 122 and the second guide plate 123 when moving along the first guide groove 124, has good stability, can ensure the movement of the material plate along the first direction, and is conducive to the transfer of the material plate between the drilling machine and the temporary storage mechanism.

[0053] In one embodiment, if Figure 1 、 Figure 5 As shown, the conveying assembly 2 further includes a plurality of drive connectors 23, each of which is transmission-connected between the output end of the driving member 21 and the corresponding clamping portion 22. The driving member 21 drives the corresponding clamping portion 22 to move in the first direction via the drive connector 23, thereby docking with the first guide groove 124. Each connecting portion 12 is provided with a second guide groove 127, which extends in the first direction and is used to guide the movement of the drive connector 23.

[0054] Driven by the driving member 21, the driving connecting member 23 drives the clamping jaw 22 to move, the clamping jaw 22 enters the first guide groove 124, and the driving connecting member 23 enters the second guide groove 127, ensuring that the driving connecting member 23 moves along the first direction. The width of the second guide groove 127 is determined according to the size of the driving connecting member 23.

[0055] In one embodiment, if Figure 2 、 Figure 4 As shown, the connecting portion 12 further includes a first connecting plate 125 and a second connecting plate 126 disposed opposite each other. The first connecting plate 125 and the second connecting plate 126 are disposed on the bottom plate 121 and extend along a first direction. The driving connector 23 includes a first driving connector 231 and a second driving connector 232 disposed opposite each other. The clamping jaw portion 22 is connected between the first driving connector 231 and the second driving connector 232.

[0056] The second guide groove 127 formed between the first connecting plate 125 and the first guide plate 122 guides the movement of the first drive connector 231, while the second guide groove 127 formed between the second connecting plate 126 and the second guide plate 123 guides the movement of the second drive connector 232. The driving member 21, through the transmission connection between the first drive connector 231 and the second drive connector 232, can drive the clamping jaw 22 to move within the first guide groove 124, ensuring a more balanced force on the clamping jaw 22 and preventing jamming during movement.

[0057] Specifically, as an example, Figure 4 As shown, the connecting portion 12 includes a first connecting plate 125 and a second connecting plate 126 disposed opposite each other. A second guide groove 127 is formed between the first connecting plate 125 and the first guide plate 122. The first guide plate 122 separates the first guide groove 124 from the second guide groove 127. Another second guide groove 127 is formed between the second connecting plate 126 and the second guide plate 123. The second guide plate 123 separates the first guide groove 124 from the second guide groove 127.

[0058] like Figure 5 As shown, the clamping jaw portion 22 is connected between the first drive connector 231 and the second drive connector 232, and the first drive connector 231 and the second drive connector 232 are respectively disposed in the two second guide grooves 127. The clamping jaw portion 22 is provided with a first connection groove 2212 and a second connection groove 2213, the first guide plate 122 is disposed in the first connection groove 2212, and the second guide plate 123 is disposed in the second connection groove 2213. During the movement of the clamping jaw portion 22, the first guide plate 122 slides along the first connection groove 2212, and the second guide plate 123 slides along the second connection groove 2213, so that the first guide plate 122 and the second guide plate 123 do not interfere with the clamping jaw portion 22 and the drive connector 23, thereby achieving the cooperation between the clamping jaw portion 22 and the connecting portion 12.

[0059] In one embodiment, if Figure 2 、 Figure 4As shown, the first guide plate 122 and the second guide plate 123 are disposed between the first connecting plate 125 and the second connecting plate 126 , and the first guide groove 124 is located between the two second guide grooves.

[0060] In one embodiment, if Figure 2 、 Figure 4 As shown, the support member 13 includes a plurality of support wheels 131 disposed on the connecting portion 12. By placing the sheet material on the plurality of support wheels 131, the sheet material can be supported and guided. At the same time, when the clamping jaws 22 drive the sheet material to move, the friction force on the sheet material can be reduced, thereby reducing the wear of the sheet material. Furthermore, the support wheels 131 are disposed on the first connecting plate 125 and the second connecting plate 126. The sheet material is supported by the support wheels 131 of the first connecting plate 125 and the support wheels 131 of the second connecting plate 126.

[0061] In one embodiment, if Figure 4 As shown, the upper surface of the support wheel 131 is located above the first guide groove 124. When the clamping jaw 22 enters the first guide groove 124, the clamping jaw 22 is located below the sheet. While the clamping jaw 22 clamps the sheet and moves along the first guide groove 124, the sheet moves on the multiple support wheels 131, thereby transporting the sheet and facilitating the clamping cooperation between the clamping jaw 22 and the sheet.

[0062] In one embodiment, if Figure 4 As shown, the drive connector 23 is a chain. A first stopper 1221 is provided on the side of the first guide plate 122 near the first connecting plate 125, and a second stopper 1251 is provided on the side of the first connecting plate 125 near the first guide plate 122. When the first drive connector 231 is engaged with the second guide groove 127 between the first guide plate 122 and the first connecting plate 125, the first stopper 1221 and the second stopper 1251 can keep the chain flat and prevent it from arching, thereby preventing the movement of the clamping jaw 22 from being affected.

[0063] A third stop 1231 is provided on the side of the second guide plate 123 close to the second connecting plate 126, and a fourth stop 1261 is provided on the side of the second connecting plate 126 close to the second guide plate 123. When the second drive connecting member 232 is engaged in the second guide groove 127 between the second guide plate 123 and the second connecting plate 126, the third stop 1231 and the fourth stop 1261 can keep the chain flat without arching.

[0064] In one embodiment, if Figure 1 、 Figure 5As shown, the drive connecting member 23 is a chain. The driving member 21 includes a motor 211, a connecting shaft 212, and a plurality of gears 213. The output end of the motor 211 is connected to the connecting shaft 212. The plurality of gears 213 are spaced apart along the axial direction of the connecting shaft 212. Each gear 213 meshes with a corresponding chain. The motor 211 drives the connecting shaft 212 to rotate, thereby driving the chain to move, thereby driving the clamping jaw 22 to move along the first direction.

[0065] When the motor 211 rotates forward, it can drive the connecting shaft 212 to rotate forward. Under the meshing action of the gear 213 and the chain, it can drive the chain to gradually extend, so that the chain drives the clamping jaw 22 to move in the first direction and approach the drilling machine. When the motor 211 rotates reversely, it can drive the connecting shaft 212 to rotate reversely. Under the meshing action of the gear 213 and the chain, it can drive the chain to reel, so that the chain drives the clamping jaw 22 to move in the first direction and away from the drilling machine, realizing the reciprocating motion of the clamping jaw 22.

[0066] In one embodiment, if Figure 5 As shown, the conveying assembly 2 further includes a mounting frame 24. The output end of the lifting mechanism 3 is connected to the mounting frame 24. The lifting mechanism 3 drives the mounting frame 24 to move up and down, thereby driving the driving member 21 and the clamping claw portion 22 to move up and down. The lifting mechanism 3 can be provided with one, two, or more lifting mechanisms 3. Preferably, two lifting mechanisms 3 are provided. The two lifting mechanisms 3 operate synchronously to drive the conveying assembly 2 to move up and down, which can improve stability during movement.

[0067] The drive member 21 is mounted on a mounting frame 24, which is provided with a receiving space 241. The drive connector 23 has a connecting end and a receiving end at its longitudinal ends. The connecting end is connected to the clamping jaw 22, while the receiving end is received in the receiving space 241. The drive member 21 is capable of driving the drive connector 23 to be released from or retracted into the receiving space 241, thereby driving the clamping jaw 22 to reciprocate in a first direction. The motor 211 drives the connecting shaft 212 to rotate, thereby driving the chain to move, enabling the chain to be released from or retracted into the receiving space 241.

[0068] In this embodiment, by providing a receiving space 241, the drive connector 23 can be retracted and extended under the drive of the motor 211, so that when the retraction and extension action is performed, the connection end drives the clamping claw portion 22 to move and form a reciprocating motion. When the motor 211 drives the drive connector 23 to be released from the receiving space 241, the drive connector 23 drives the clamping claw portion 22 away from the temporary storage rack 1 in the first direction. When the motor 211 drives the drive connector 23 to be retracted into the receiving space 241, the drive connector 23 drives the clamping claw portion 22 toward the temporary storage rack 1 in the first direction. The clamping claw portion 22 clamps the material sheet, and as the drive connector 23 moves, the material sheet is transported.

[0069] In one embodiment, if Figure 5 、 Figure 6 As shown, the clamping jaw portion 22 includes a connecting base 221, a clamping jaw driving member 222, and a clamping jaw 223. The connecting base 221 is connected to the connecting end, and the clamping jaw driving member 222 is mounted on the connecting base 221. The output end of the clamping jaw driving member 222 is connected to the clamping jaw 223 to drive the clamping jaw 223 to compress or release the sheet. The first connecting groove 2212 and the second connecting groove 2213 are provided on the connecting base 221.

[0070] When the sheet needs to be compressed, the motor 211 drives the connecting base 221 to move toward the sheet, and the jaw driver 222 drives the jaws 223 to move and compress the sheet. After compressing the sheet, the motor 211 drives the connecting base 221 to reciprocate, driving the sheet clamped by the jaws 223 to move. When the sheet reaches the desired position, the jaw driver 222 drives the jaws 223 to release the sheet.

[0071] In one embodiment, if Figure 6 As shown, the connecting base 221 is provided with a receiving groove 2211 for accommodating the clamping jaw 223. When the clamping jaw 223 is located in the receiving groove 2211, the clamping jaw 223 is in a closed state. The clamping jaw 223 is driven to move upward in the vertical direction by the clamping jaw driving member 222. When the clamping jaw 223 leaves the receiving groove 2211, the clamping jaw 223 is in an open state. At this time, there is a gap between the clamping jaw 223 and the connecting base 221. After the material sheet enters the gap, the clamping jaw driving member 222 drives the clamping jaw 223 to move toward the connecting base 221, thereby clamping the material sheet between the clamping jaw 223 and the connecting base 221.

[0072] During the loading and unloading process, when the material sheet is sent from the temporary storage rack 1 to the drilling machine, the clamping jaw part 22 enters the first guide groove 124. At this time, the clamping jaw 223 is accommodated in the accommodating groove 2211 and is in a closed state. The driving member 21 drives the clamping jaw part 22 to move to the first edge of the material sheet. The clamping jaw driving member 222 drives the clamping jaw 223 to clamp the material sheet. The driving member 21 drives the clamping jaw part 22 to move along the first guide groove 124 until it enters the drilling machine, and the material sheet is overlapped on the drilling machine. Then, the clamping jaw portion 22 continues to move forward a short distance, and the clamping jaw driving member 222 drives the clamping jaw 223 to be accommodated in the accommodating groove 2211. The driving member 21 drives the clamping jaw portion 22 to move along the first guide groove 124 from the bottom of the material plate to the second edge of the material plate. After the clamping jaw driving member 222 drives the clamping jaw 223 to clamp the second edge of the material plate, the driving member 21 drives the clamping jaw portion 22 to move toward the drilling machine, thereby pushing the material plate to move toward the drilling machine until the material plate stops moving after it is in place.

[0073] When the material sheet is fed from the drilling machine to the temporary storage rack 1, the driving member 21 drives the clamping jaw portion 22 to approach the material sheet and clamp the second edge of the material sheet. The driving member 21 drives the clamping jaw portion 22 away from the drilling machine until a part of the material sheet enters the temporary storage rack 1, the clamping jaw portion 22 releases the material sheet, and the clamping jaw driving member 222 drives the clamping jaw 223 to be accommodated in the accommodating groove 2211. The driving member 21 drives the clamping jaw portion 22 to move along the first guide groove 124 from the bottom of the material sheet to the first edge of the material sheet. After re-clamping the material sheet, the driving member 21 drives the clamping jaw portion 22 away from the drilling machine, and the clamping jaw portion 22 pushes the material sheet to move toward the temporary storage rack 1 until the material sheet completely enters the temporary storage rack 1.

[0074] In one embodiment, if Figure 2 As shown, the temporary storage mechanism further includes a plurality of lifting assemblies 4 , which move independently of each other. Each lifting assembly 4 is disposed at a corresponding connecting portion 12 , and the lifting assembly 4 is used to lift the sheet material off the support member 13 .

[0075] The motor 211 is driven by the connecting shaft 212, the gear 213 and the drive connector 23, and the multiple clamping jaws 22 move simultaneously, which can simultaneously transport multiple material sheets. When a certain material sheet needs to be transported independently, the material sheet is lifted by the lifting assembly 4, so that the material sheet rises and leaves the support 13. When the clamping jaws 22 enter the first guide groove 124 and the clamping jaw driving member 222 drives the clamping jaws 223 to move up and down, the clamping jaws 223 cannot contact the material sheet and cannot clamp the material sheet between the clamping jaws 223 and the connecting seat 221. During the movement of the clamping jaws 22 along the first guide groove 124, the material sheet cannot be clamped and transported. For material sheets that do not need to be unloaded, they can be lifted by the lifting assembly 4, which can also realize the conveying of multiple material sheets on the temporary storage rack 1 one by one.

[0076] In one embodiment, if Figure 4 As shown, the jacking assembly 4 includes a mounting seat 41, a jacking cylinder (not shown in the figure) and a support plate 42. The mounting seat 41 is installed on the connecting part 12, the jacking cylinder is installed on the mounting seat 41, and the output end of the jacking cylinder is connected to the support plate 42 to drive the support plate 42 to move and lift the material plate.

[0077] The support plate 42 extends along the first direction, and the number of lifting cylinders can be one, two, or more. Preferably, two lifting cylinders are provided, and the two lifting cylinders are spaced apart along the length of the support plate 42. The two lifting cylinders operate synchronously to drive the support plate 42 up and down, which can improve the stability during lifting. When the sheet material is not being conveyed, the two lifting cylinders drive the support plate 42 to rise, and the support plate 42 lifts the sheet material away from the support member 13, so that the lifted sheet material cannot be clamped and conveyed.

[0078] In one embodiment, if Figure 2As shown, two jacking assemblies 4 are provided, and the two jacking assemblies 4 are installed on opposite sides of the connecting portion 12. Through the synchronous movement of the two jacking assemblies 4, the material plate can be lifted and lowered smoothly.

[0079] On the other hand, an embodiment of the present invention provides a drilling machine, including the temporary storage mechanism of the above embodiment, the drilling machine includes a workbench, the temporary storage mechanism is arranged on one side of the workbench, the temporary storage mechanism sends the material plate to the workbench, and the main shaft of the drilling machine drills the material plate on the workbench.

[0080] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
