[0028] The PCB processing equipment generally uses a mechanical hand to load and unload the PCB on the workbench, and the middle region of the workbench plate used for the PCB with PIN pegs is provided with a positioning groove, when loading, the mechanical hand places the PCB on the workbench plate, and the PIN pegs on the PCB are inserted and clamped in the positioning groove, so that the PCB plate is stably fixed on the workbench plate, and accurate positioning is provided for the subsequent processing procedure.

[0029] When unloading, the clamping jaw of the mechanical hand clamps the PCB on the left and right sides of the workbench plate. The existing workbench plate generally includes a middle plate and side plates located on the left and right sides of the middle plate, the middle plate is made of high-strength steel material, and the side plates are made of aluminum alloy material. In order to ensure the stability of the clamping of the mechanical hand, the clamping jaw is generally made of high-strength steel, and when the clamping jaw of the mechanical hand clamps the PCB on the workbench plate, the side plates made of aluminum alloy material are easy to appear difficult to reverse scratch marks due to the high hardness friction of the clamping jaw, which reduces the flatness and precision of the workbench plate. Moreover, after long-time wear, the workbench plate needs to be replaced, and the replacement cost is high.

[0030] To solve the above problems, an embodiment of the utility model provides a kind of PCB processing equipment.

[0031] The PCB processing equipment includes a mechanical hand, a machine table 300 and a PCB workbench plate, the PCB workbench plate is arranged on the machine table 300, and the mechanical hand is provided with a clamping jaw, and the PCB processing equipment can drill and so on to the plate material 400 on the PCB workbench plate.

[0032] As shown in Figure 1 And Figure 2 The PCB workbench plate includes a main plate 200 and a pad plate 100 detachably laid on the main plate 200, the pad plate 100 is used to place the plate material 400, and the plate material 400 is provided with a positioning piece 401. The main plate 200 is provided with a positioning groove 201 with an opening facing the pad plate 100, and the pad plate 100 is provided with an emptying groove 11 penetrating along the thickness direction thereof, and the emptying groove 11 is communicated with the positioning groove 201.

[0033] The PCB workbench is based on the main bench 200 (i.e. the existing workbench) and is paved with a layer of the cushion plate 100. The "board 400" includes but is not limited to PCB, wood board, etc. The positioning member 401 can be a screw, a pin, also commonly known as a PIN pin.

[0034] When feeding, the gripper of the manipulator places the board 400 on the cushion plate 100, and the clearance groove 11 avoids the positioning member 401, so that the positioning member 401 can be inserted into the positioning groove 201. Thus, the PCB processing equipment can clamp the positioning member 401 on the board 400 in the positioning groove 201, so that the board 400 is stably fixed on the PCB workbench, providing accurate positioning for subsequent processing procedures.

[0035] When discharging, the gripper clamps the board 400 placed flat on the cushion plate 100, and the gripper is against the cushion plate 100 and clamps the opposite sides of the board 400. The cushion plate 100 can effectively isolate the main bench 200 and the gripper, greatly reducing the scratches of the main bench 200 caused by the high hardness friction of the gripper. As a consumable part, the cushion plate 100 can prolong the service life of the main bench 200. Even if the cushion plate 100 is worn out with the increase of the use time, the cushion plate 100 can be regularly inspected and replaced. Compared with directly replacing the expensive main bench 200, the cost of the cushion plate 100 is relatively low.

[0036] The PCB processing equipment of the utility model, PCB workbench is based on the existing main bench 200, and is paved with a layer of detachable cushion plate 100, and when feeding, board 400 is placed on the cushion plate 100, and the clearance groove 11 of the cushion plate 100 avoids the positioning member 401, so that the positioning member 401 can be inserted into the positioning groove 201. When discharging, the cushion plate 100 can effectively isolate the main bench 200 and the gripper when the gripper of the manipulator clamps the board 400 on the cushion plate 100, greatly reducing the scratches of the main bench 200 caused by the high hardness friction of the gripper, reducing the production cost and time waste caused by frequent replacement. As a consumable part, the cushion plate 100 can prolong the service life of the main bench 200. Even if the cushion plate 100 is worn out with the increase of the use time, the cushion plate 100 can be regularly inspected and replaced. Compared with directly replacing the expensive main bench 200, the cost of the cushion plate 100 is relatively low, the maintenance cost is reduced, and the flexibility and sustainability of the overall production line are improved.

[0037] In an embodiment, as shown in Figure 1 The main bench 200 includes an intermediate bench 202 and side benches located on both sides of the intermediate bench 202 along the first direction. The intermediate bench 202 is made of high-strength steel material, and the side benches are made of aluminum alloy material. The intermediate bench 202 has extremely high strength and hardness, can withstand the huge impact force generated during the drilling of the board 400, and maintains the overall stability and rigidity of the workbench.

[0038] In an embodiment, as shown in Figure 2 The base plate 100 includes a clearance assembly 1 and a bearing assembly 2, the bearing assembly 2 is arranged on both sides of the clearance assembly 1 along the first direction, the clearance groove 11 is arranged in the clearance assembly 1, the strength of the clearance assembly 1 is higher than that of the bearing assembly 2, and the bearing assembly 2 is used to bear the plate 400. Figure 2 D1 in the figure indicates the first direction, and the first direction is the relative direction of the opposite sides of the plate 400 clamped by the gripper of the manipulator.

[0039] The clearance assembly 1 with relatively high strength can withstand the impact force generated during the processing of the PCB by the PCB processing equipment, and maintain the overall stability and rigidity of the entire workbench plate. Moreover, since the PIN pin on the plate 400 will wear the clearance assembly 1 when inserted into the positioning groove 201, the strength of the clearance assembly 1 needs to be relatively high to reduce the wear of the PIN pin on the clearance assembly 1. The strength of the bearing assembly 2 is relatively weak, and the friction between the bearing assembly 2 and the gripper made of high-strength steel is relatively small, so that the base plate 100 has the advantages of high intermediate strength and small wear on both sides, thereby improving the service life of the base plate 100.

[0040] In an embodiment, the clearance assembly 1 and the bearing assembly 2 are independently arranged on the main bench plate 200, so that the clearance assembly 1 and the bearing assembly 2 can be replaced according to their own wear conditions respectively, without the need to replace the entire base plate 100 at one time, thereby further reducing the cost.

[0041] In an embodiment, as shown in Figure 1 The PCB processing equipment includes a plurality of PCB workbench plates, and the plurality of PCB workbench plates are arranged in sequence along the first direction, wherein, Figure 1 Only the base plate 100 on one of the PCB workbench plates is shown, and the clearance assembly 1 on the remaining PCB workbench plates is hidden. Figure 1 D1 in the figure indicates the first direction.

[0042] In other embodiments, the clearance assembly 1 and the bearing assembly 2 can be integrally formed.

[0043] In an embodiment, the bearing assembly 2 is a plastic plate, and the clearance assembly 1 is a metal plate.

[0044] In an embodiment, the bearing assembly 2 is made of high-performance polypropylene (PP) material, which not only has excellent wear resistance, but also greatly reduces the frictional resistance between the drill bit and the PCB workbench plate of the PCB processing equipment due to its good self-lubricating properties, thereby improving the smoothness and accuracy of the drilling operation. The bearing assembly 2 made of PP material can effectively prevent the direct contact between the clamping jaw and the main plate 200, greatly reducing the damage caused by friction, and due to the processability of the material, it can perfectly fit the shape of the main plate 200 and the clamping jaw, ensuring accurate operation when placing the clamping jaw. In addition, the PP material also has certain impact resistance and chemical stability, ensuring the stable operation of the PCB workbench plate in various complex environments.

[0045] In an embodiment, the avoidance assembly 1 is made of S136H (high-strength steel) to maintain the original advantages of the PCB processing equipment. The avoidance assembly 1 is made of the same material as the original main plate 200. S136H steel has extremely high strength and hardness, can withstand the huge impact force generated during drilling, and maintains the overall stability and rigidity of the PCB workbench plate.

[0046] In an embodiment, the main plate 200 is provided with positioning holes (not shown in the figure), and the cushion plate 100 is provided with positioning pins (not shown in the figure) matching the positioning holes, so that the cushion plate 100 can be detachably laid on the main plate 200 through the insertion and cooperation of the positioning pins and the positioning holes, which is simple in structure and convenient to disassemble and assemble.

[0047] In other embodiments, the cushion plate 100 can be detachably connected to the main plate 200 through screws, rivets or clamping structures.

[0048] In an embodiment, as shown in Figure 2 and Figure 3 , the avoidance slot 11 has a top opening and a bottom opening, the size of the top opening along the first direction is greater than the size of the bottom opening along the first direction, and the bottom opening corresponds to the opening of the positioning slot 201.

[0049] Figure 2 D1 in the above formula represents the first direction, and the first direction is the relative direction of the opposite sides of the gripper clamping plate 400 of the manipulator.

[0050] When loading, the gripper clamping plate 400 of the manipulator is placed on the cushion plate 100, the positioning member 401 is inserted into the avoidance slot 11 from the top opening, and then inserted into the positioning slot 201 from the bottom opening. The size of the top opening along the first direction is greater than the size of the bottom opening along the first direction, the opening space of the avoidance slot for the insertion of the positioning member 401 on the plate 400 is larger, the placement error is increased, which is beneficial to the alignment and insertion of the positioning member 401 into the avoidance slot when the manipulator clamps the plate 400, and is beneficial to the automatic loading and unloading of the plate 400.

[0051] In an embodiment, as shown in Figure 3 The avoidance slot 11 extends along the second direction, and includes a constant diameter section and a flared section distributed along the thickness direction of the cushion plate 100, the bottom opening is arranged on the constant diameter section, and the top opening is arranged on the flared section, and the size of the flared section along the first direction gradually increases in the direction away from the constant diameter section; wherein the first direction is perpendicular to the second direction.

[0052] When loading, the gripper of the manipulator clamps the plate 400 to be placed on the cushion plate 100, the positioning member 401 is inserted into the flared section and the constant diameter section in turn, and then inserted into the positioning slot 201, and the flared section with the size gradually increasing in the direction away from the constant diameter section along the first direction can guide the positioning member 401 to be inserted into the constant diameter section, having a guiding effect.

[0053] In an embodiment, as shown in Figure 4 The plate 400 is provided with two positioning members 401 distributed at intervals on a straight line, and the straight line extends along the second direction. Correspondingly, the main table plate 200 is provided with first positioning slots and second positioning slots distributed at intervals along the second direction, the first positioning slots extend along the second direction, and the second positioning slots are circular or square. The cushion plate 100 is provided with two avoidance slots 11, which are a first avoidance slot and a second avoidance slot, the first avoidance slot is a long strip shape extending along the second direction and is in communication with the first positioning slot, and the second avoidance slot is circular or square and is in communication with the second positioning slot.

[0054] When the plate 400 is placed on the cushion plate 100, one of the positioning members 401 passes through the first avoidance slot and is inserted into the first positioning slot, and the other positioning member 401 passes through the second avoidance slot and is inserted into the second positioning slot.

[0055] Of course, in other embodiments, the two avoidance slots 11 can both be long strip shapes extending along the second direction, or both be square or circular.

[0056] The plate 400 is positioned by being provided with two positioning members 401, which has two main advantages: first, through the joint action of the two positioning members 401, the plate 400 is more stably fixed to prevent it from moving or deviating during processing; second, since the two positioning members 401 are located on the same straight line, the straightness can be used to ensure the accuracy during operation. When the plate 400 is placed on the PCB workbench plate, the positioning slot 201 will match the positioning member 401. In this way, the plate 400 is stably fixed on the PCB workbench plate, providing an accurate reference for the subsequent processing procedures.

[0057] In an embodiment, the flared section has a first sidewall and a second sidewall oppositely arranged along the first direction, and at least one of the first sidewall and the second sidewall is provided with a relief chamfer for guiding the positioning member 401 to be inserted into the constant diameter section.

[0058] In other embodiments, the sidewall of the flared section can be a curved surface curved outward in a direction away from the constant diameter section.
