[0044] 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.

[0045] like Figures 1 to 7 As shown, one embodiment of the present invention provides a PCB processing device comprising a processing machine 1, a material rack 2, and a robot 3. The processing machine 1 is used to process a material plate. The material rack 2 comprises a base 21 and a plurality of support frames 22. The support frames 22 are slidably mounted on the surface of the base 21 and are movable on the surface of the base 21. This allows the support frames 22 to be adjusted in position according to the actual size of the material plate, increasing the flexibility of the material rack 2 and enabling it to accommodate material plates of different sizes.

[0046] A plurality of support members 224 are arranged at intervals along the first direction a on the support frame 22. The support members 224 of the plurality of support frames 22 are used to support the material sheets. The plurality of support members 224 jointly support the material sheets to ensure that the material sheets can be stably placed on the material frame 2. Since the support members 224 are arranged at intervals, the plurality of material sheets are arranged at intervals along the first direction a on the material frame 2. Adjacent material sheets cannot fit together and have a certain interval, which facilitates the robot 3 to pick up the material sheets.

[0047] The adjacent two support frames 22 form a material taking opening 23 extending along the first direction a. The robot 3 comprises a mechanical arm 31, a mounting frame 33 mounted at the end of the mechanical arm 31, and a plurality of telescopic clamping pieces 32 mounted on the mounting frame 33 and arranged around the end of the mechanical arm 31, each telescopic clamping piece 32 can enter or exit the corresponding material taking opening 23, the material taking opening 23 provides an operation space for the operation of the telescopic clamping piece 32, and the telescopic directions of at least two of the plurality of telescopic clamping pieces 32 are different, by adjusting the telescopic clamping piece 32, the robot 3 can adapt to the clamping of material plates of different shapes and sizes.

[0048] When the plurality of telescopic clamping pieces 32 are clamped around the material plate, the mechanical arm 31 can drive the plurality of telescopic clamping pieces 32 to move, so that the material plate can be transferred between the material rack 2 and the processing machine table 1.

[0049] In the embodiment, the plurality of support frames 22 are slidably arranged on the base 21, by sliding the support frame 22, the position of the support frame 22 on the base 21 can be adjusted, so that the material rack 2 can accommodate material plates of multiple different sizes. The robot 3 telescopes in different directions through the plurality of telescopic clamping pieces 32, when facing material plates of different sizes, the size of the clamping range of the plurality of telescopic clamping pieces 32 can be adjusted, so that the robot 3 can take material from material plates of different sizes. Therefore, when loading the processing machine table 1, through the cooperation of the plurality of support frames 22 and the plurality of telescopic clamping pieces 32, the loading of material plates of different sizes can be adapted, avoiding the existing situation of setting multiple specifications for the material box and the material taking mechanism of the robot 3, so that the PCB processing equipment does not need to change the specifications of the material box and the robot 3 when processing multiple different sizes of material plates, reducing the downtime for replacement, thereby improving the processing efficiency of the material plate.

[0050] In a specific embodiment, as shown in Figure 2 The telescopic clamping piece 32 is provided with four telescopic clamping pieces 32, two of which are oppositely arranged, and the other two are oppositely arranged. In a three-dimensional orthogonal coordinate system, the first direction a, the second direction b and the third direction c are perpendicular to each other. Two telescopic clamping pieces 32 along the second direction b can move closer to or away from each other in the second direction, and the other two telescopic clamping pieces 32 along the third direction c can move closer to or away from each other in the third direction, the four telescopic clamping pieces 32 are arranged in a cross shape and can be clamped around the material plate.

[0051] In an embodiment, as shown in Figure 1As shown, the robot 3 further comprises an automatic guided vehicle 35, and the mechanical arm 31 is installed on the automatic guided vehicle 35, and the automatic guided vehicle 35 is used to move between the magazine and the processing machine table 1, so as to facilitate the mechanical arm 31 to drive the plurality of telescopic clamping pieces 32 to transfer the plate between the magazine rack 2 and the processing machine table 1.

[0052] In an embodiment, as shown in Figure 1 、 Figure 2 As shown, the mounting frame 33 is provided with a plurality of first driving pieces 34, and the plurality of first driving pieces 34 are connected with the plurality of telescopic clamping pieces 32 one by one, and each telescopic clamping piece 32 can be independently controlled by the corresponding first driving piece 34, which enables the robot 3 to accurately adjust the telescopic action of each telescopic clamping piece 32, so that the plurality of telescopic clamping pieces 32 can clamp plate materials of different sizes and shapes, and ensure the stability and accuracy of clamping.

[0053] The first driving piece 34 can drive the telescopic clamping piece 32 to reciprocate along the telescopic direction, so that the telescopic clamping piece 32 can clamp or release the plate. When the robot 3 takes the plate, the first driving piece 34 drives the telescopic clamping piece 32 to move away from the mechanical arm 31 along the telescopic direction, so as to increase the clamping range defined by the plurality of telescopic clamping pieces 32, and after the mechanical arm 31 drives the telescopic clamping piece 32 to enter the taking opening 23, the plate can be in the clamping range of the plurality of telescopic clamping pieces 32, and then the first driving piece 34 drives the telescopic clamping piece 32 to move close to the plate along the telescopic direction, and after the telescopic clamping piece 32 moves to the clamping position, the edge of the plate is clamped, so as to realize the clamping of the plate.

[0054] In an embodiment, as shown in Figure 2 The mounting frame 33 comprises a connecting piece 331 and a plurality of mounting beams 332, the connecting piece 331 is connected with the mechanical arm 31, the plurality of mounting beams 332 extend along different directions and are arranged around the connecting piece 331, the first driving piece 34 is installed on the mounting beam 332, and the plurality of telescopic clamping pieces 32 are respectively and one by one installed on one end of the plurality of mounting beams 332 away from the connecting piece 331. The connecting piece 331 and the mounting beam 332 can realize the connection between the telescopic clamping piece 32 and the mechanical arm 31, so that the telescopic clamping piece 32 moves under the drive of the mechanical arm 31.

[0055] The connection between the mounting beam 332 and the connecting piece 331 and the telescopic clamping piece 32 enables the plurality of telescopic clamping pieces 32 to be arranged around the connecting piece 331, and when the plate is grabbed, the plurality of telescopic clamping pieces 32 can grab different positions of the outer edge of the plate, so as to realize the clamping and releasing of the plate.

[0056] Further, the plurality of mounting beams 332 are distributed radially around the connecting piece 331, one end of each of the plurality of mounting beams 332 is connected with the connecting piece 331, so that the plurality of telescopic clamping pieces 32 are arranged around the connecting piece 331, and then the plurality of telescopic clamping pieces 32 are arranged to grab the edges of the material plate.

[0057] The number of mounting beams 332 is determined according to the size of the material plate, to ensure the stability of the plurality of telescopic clamping pieces 32 when clamping the edges of the material plate, and to reduce the situation of the material plate falling off. It can be understood that when the telescopic clamping piece 32 grabs other materials, the number of mounting beams 332 can be changed according to the shape of the material and the clamping stability.

[0058] In a specific embodiment, as shown in Figure 2 , the material plate is a PCB, and the shape of the PCB is square. Four mounting beams 332 are arranged around the connecting piece 331, and four telescopic clamping pieces 32 are arranged. In order to facilitate the description of the structure of the mounting frame 33, the four mounting beams 332 are respectively named as a first mounting beam, a second mounting beam, a third mounting beam and a fourth mounting beam.

[0059] In order to clamp the PCB, the first mounting beam and the second mounting beam are both extended along the second direction b and arranged on opposite sides of the connecting piece 331 in the second direction b, the third mounting beam and the fourth mounting beam are both extended along the third direction c and arranged on opposite sides of the connecting piece 331 in the third direction c, and the second direction b and the third direction c are perpendicular. In this way, the four mounting beams 332 are connected by the connecting piece 331 to form a cross-shaped structure, in the second direction b, the telescopic clamping piece 32 on the first mounting beam and the telescopic clamping piece 32 on the second mounting beam are oppositely arranged and can be clamped on opposite sides of the second direction b of the PCB. In the third direction c, the telescopic clamping piece 32 on the third mounting beam and the telescopic clamping piece 32 on the fourth mounting beam are oppositely arranged and can be clamped on opposite sides of the third direction c of the PCB. In this way, the four telescopic clamping pieces are clamped on the four edges of the PCB respectively, and the telescopic clamping arranged on the four edges satisfies the stability of the PCB grabbing. Among them, the second direction b is the X direction, and the third direction c is the Y direction.

[0060] In an embodiment, as shown in Figure 2 , Figure 3As shown, the first driving member 34 comprises a motor 341, a screw rod 342, a screw nut 343 and a transition member 344, the motor 341 is installed on the mounting beam 332, one end of the screw rod 342 is connected with the output end of the motor 341, the screw nut 343 is sleeved on the outside of the screw rod 342 and is threadedly connected with the screw rod 342, one end of the transition member 344 is connected with the screw nut 343, and the other end of the transition member 344 is connected with the telescopic clamping member 32, when the motor 341 drives the screw rod 342 to rotate, the screw nut 343 can move along the screw rod 342, so as to drive the telescopic clamping member 32 to move through the transition member 344, so that the telescopic clamping member 32 can approach or move away from the mounting beam 332, and the telescopic action of the telescopic clamping member 32 on the mounting frame 33 is realized.

[0061] In an embodiment, as shown in Figure 2 The mounting frame 33 further comprises a guide portion 333, the guide portion 333 is installed at the end of the mounting beam 332 away from the connecting member 331, and the guide portion 333 is arranged between the mounting beam 332 and the telescopic clamping member 32.

[0062] The guide portion 333 comprises a guide block 3331 and a guide rod 3332, the guide block 3331 is installed at the end of the mounting beam 332 away from the connecting member 331, one end of the guide rod 3332 is connected with the telescopic clamping member 32, and the other end of the guide rod 3332 penetrates the guide block 3331, when the first driving member 34 drives the telescopic clamping member 32 to move, the guide rod 3332 moves along with the telescopic clamping member 32, the guide rod 3332 can slide relative to the guide block 3331, so that the guide block 3331 guides the guide rod 3332 when the first driving member 34 drives the telescopic clamping member 32 to move, and the telescopic clamping member 32 performs controllable linear motion along the guide rod 3332 under the drive of the motor 341, so as to realize the reciprocating movement of the telescopic clamping member 32.

[0063] Among them, the guide block 3331 is embedded with a linear bearing, and the guide rod 3332 penetrates the linear bearing, constituting a linear guide rail pair, so as to ensure the smooth operation of the guide rod 3332.

[0064] In an embodiment, as shown in Figure 2 The mounting beam 332 is provided with an avoiding groove 3321, and the end of the guide rod 3332 away from the telescopic clamping member 32 can penetrate the guide block 3331 and enter the avoiding groove 3321, so that when the telescopic clamping member 32 approaches the mounting beam 332, the part of the guide rod 3332 penetrating out of the guide block 3331 can be avoided through the avoiding groove 3321.

[0065] In an embodiment, as shown in Figure 2As shown, the guide block 3331 is provided with an inductor 33311, and the telescopic holder 32 is provided with an inductive sheet 3212. When the telescopic holder 32 is moved under the drive of the first driving member 34, the inductive sheet 3212 moves with the telescopic holder 32, so that the inductive sheet 3212 can approach or move away from the inductor 33311. The inductor 33311 is used for the inductive sheet 3212 to control the moving stroke of the telescopic holder 32 when the telescopic holder 32 approaches the mounting beam 332, so as to limit the stroke limit of the telescopic holder 32. When the inductive sheet 3212 triggers the inductor 33311, the telescopic holder 32 stops moving, so as to avoid the telescopic holder 32 from colliding with the mounting beam 332 under the drive of the first driving member 34, and thus avoid damaging the telescopic holder 32.

[0066] In an embodiment, as shown in Figure 4 、 Figure 5 The telescopic holder 32 comprises a mounting seat 321, a second driving member 322 and a jaw head 323. The inductive sheet 3212 is mounted on the mounting seat 321, and the mounting seat 321 is connected with the output end of the first driving member 34. The guide block 3331 is mounted on the mounting beam 332, one end of the guide rod 3332 is fixed on the mounting seat 321, and the other end of the guide rod 3332 is arranged in the guide block 3331, so as to guide the movement of the telescopic holder 32.

[0067] The second driving member 322 is mounted on the mounting seat 321, the first end of the jaw head 323 is connected with the output end of the second driving member 322, and the second end of the jaw head 323 protrudes from the mounting seat 321 along the first direction a, so as to form a clamping space 327 between the mounting seat 321 and the second end of the jaw head 323 for accommodating part of the material plate.

[0068] The second driving member 322 can drive the jaw head 323 to reciprocate along the first direction a, so as to clamp or release the material plate between the jaw head 323 and the mounting seat 321. When the telescopic holder 32 moves to the edge of the material plate, the first driving member 34 drives the telescopic holder 32 to approach the mounting beam 332, so that the edge of the material plate enters the clamping space 327. Then, when the second driving member 322 drives the jaw head 323 to move upward along the first direction a, the distance between the second end of the jaw head 323 and the lower surface of the mounting seat 321 is reduced, so that the material plate is clamped. When the second driving member 322 drives the jaw head 323 to move downward along the first direction a, the distance between the second end of the jaw head 323 and the lower surface of the mounting seat 321 is increased, so as to release the clamping of the material plate. Finally, after the first driving member 34 drives the telescopic holder 32 to move away from the mounting beam 332, the telescopic holder 32 is separated from the material plate.

[0069] In an embodiment, as shown in Figure 4、 Figure 5 As shown, a guide groove 3211 extending along the first direction a is provided on the mounting seat 321, and the output end of the second driving member 322 can extend into the guide groove 3211. The first end of the clamping head 323 is provided in the guide groove 3211 and is connected to the output end of the second driving member 322. The second end of the clamping head 323 protrudes from the guide groove 3211, and the movement of the clamping head 323 can be guided by the guide groove 3211.

[0070] In one embodiment, the second driving member 322 is a screw stepping motor, and the screw of the screw stepping motor can perform linear motion, thereby driving the clamping jaw head 323 to move up and down.

[0071] In one embodiment, if Figure 5 As shown, the telescopic clamping member 32 also includes a connecting shaft 324 and an elastic member 325. One end of the connecting shaft 324 is connected to the output end of the second driving member 322. The elastic member 325 is sleeved on the outer periphery of the connecting shaft 324. The first end of the clamping claw head 323 is slidably connected to the connecting shaft 324 and abuts against the elastic member 325. When the second end of the clamping claw head 323 and the mounting seat 321 clamp the material plate, the first end of the clamping claw head 323 squeezes the elastic member 325 so that the elastic member 325 applies a thrust force toward the second driving member 322 to the first end of the clamping claw head 323.

[0072] After the material sheet enters the clamping space 327, the second driving member 322 drives the clamping head 323 to move upward. When the material sheet contacts the second end of the clamping head 323, as the clamping head 323 continues to move upward, under the pressure of the material sheet, the first end of the clamping head 323 squeezes the elastic member 325. The elastic member 325 is squeezed to generate an elastic force along the first direction. The elastic force of the elastic member 325 can act on the clamping head 323, and then act on the material sheet through the clamping head 323, which can increase the clamping effect on the material sheet.

[0073] In one embodiment, the elastic member 325 is a spring.

[0074] In one embodiment, if Figure 4 、 Figure 5As shown, the telescopic clamping member 32 further comprises a frame member 326, which is arranged in the guide groove 3211, and the mounting position of the elastic member 325 and the connecting shaft 324 is defined by the frame member 326 and the guide groove 3211. The connecting shaft 324 and the elastic member 325 are arranged inside the frame member 326, one end of the connecting shaft 324 protrudes from the frame member 326 and is connected with the output end of the second driving member 322, and the first end of the clamping jaw head 323 is located between the elastic member 325 close to the second driving member 322 and the frame member 326. Under the driving of the second driving member 322, the frame member 326 can be driven to move through the connecting shaft 324, and the frame member 326 moves along the guide groove 3211, thereby guiding the movement of the clamping jaw head 323 in the first direction a.

[0075] In an embodiment, as shown in Figure 5 The frame member 326 is a U-shaped frame, and the opening direction of the U-shaped frame faces the clamping jaw head 323. When the material plate is pressed against the second end of the clamping jaw head 323 to press the elastic member 325, the clamping jaw head 323 can move on the opening side of the U-shaped frame without interference.

[0076] In an embodiment, as shown in Figure 2 The mounting frame 33 further comprises an edge-finding sensor 334 and a height sensor 335, which are arranged on the mounting beam 332.
