Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0023] As Figures 1-6 shown, the embodiments of the present utility model include:

[0024] A material plate milling processing interval displacement transmission equipment, including a machine table 1, a milling station 2, a transfer platform 3, a material plate rotating table 4, a material plate shelf 5, a guide push arm 6, an X-axis multi-moving linear module 7, and a material plate suction cup 8. The machine table 1 is divided into two groups of milling stations 2, a transfer platform 3 is arranged between the milling stations 2, a material plate rotating table 4 is arranged on the transfer platform 3, material plates shelves 5 and guide push arms 6 are respectively arranged on both sides of the material plate rotating table 4, an X-axis multi-moving linear module 7 is arranged between the milling station 2 and the transfer platform 3, and a plurality of material plate suction cups 8 that travel back and forth between the milling station 2 and the transfer platform 3 are mounted on the X-axis multi-moving linear module 7.

[0025] Among them, loading and unloading platforms 9 are arranged at both ends of the machine 1, and both ends of the X-axis multi-moving linear module 7 are respectively connected with the loading and unloading platforms 9, a Z-axis linear module 10 is hoisted under the machine 1, and a lifting bracket 11 connected to the Z-axis linear module 10 is arranged at the bottom of the loading and unloading platform 9.

[0026] Furthermore, a sheet material retaining wall 12 is provided at the edge of the machine platform 1 , which covers the travel range of the loading and unloading platform 9 and semi-encloses and abuts against two adjacent edges of the loading and unloading platform 9 .

[0027] Furthermore, the milling station 2 is provided with a Y-axis linear module 13 passing through the X-axis multi-moving linear module 7 , and the end of the Y-axis linear module 13 is matched with a milling spindle 14 .

[0028] Furthermore, a first bracket 15 is mounted on the Y-axis linear module 13 , a second bracket 16 which is parallel to and has the same height as the first bracket 15 is provided on the machine platform 1 , and a plate clamp 17 is crimped onto the first bracket 15 .

[0029] Furthermore, one end of the plate clamp 17 is provided with a fingertip 18 acting on the surface of the first bracket 15, and the other end is provided with a sleeve 19. Several plate clamps 17 are sleeved on a rotating shaft 31 parallel to the first bracket 15 through the sleeve 19 and locked by a top screw 30. The outer wall of the rotating shaft 31 is axially provided with an orientation groove 32, and the inner wall of the sleeve 19 is provided with a protrusion 33 that is aligned with the fingertip 18 and matched with the orientation groove 32. The rotating shaft 31 is coaxially connected to the external motor 34 and is mounted on a pair of bearing seats 35. The bearing seat 35 is mounted on the Y-axis linear module 13 through an adapter bracket 36.

[0030] Furthermore, a plurality of linearly arranged rollers 37 are disposed on the upper edge of the second bracket 16 , and an X-axis linear slide 38 that carries the second bracket 16 is disposed on the machine platform 1 .

[0031] Further, the transfer platform 3 is set as a magnetic punching plate, on which a reference frame 39 is fixed and a first adjustable base 40 is magnetically attracted. The material plate shelf 5 is installed on the upper edge of the reference frame 39 in the form of a right-angle side arrangement. The guiding and pushing arm 6 is horizontally installed on the first adjustable base 40 through a slide table cylinder 41. The guiding and pushing arm 6 is provided with a guiding notch 42 in a right-angle shape, and a number of rollers 37 arranged linearly are provided on the upper edge of the material plate shelf 5.

[0032] Further, the material plate rotating table 4 is carried on a rotating cylinder 43, a negative pressure suction cup 44 is arranged in the center of the material plate rotating table 4, the rotating cylinder 43 is carried on a second adjustable base 45, and the second adjustable base 45 is adsorbed on the transfer platform 3.

[0033] Further, three sets of moving sub-slides are arranged on the X-axis multi-moving sub linear module 7, and a Z-axis slide table cylinder 46 is arranged on each moving sub-slide. The Z-axis slide table cylinder 46 is connected to a horizontal punching plate 47 below, a number of negative pressure connectors 48 are hung on the horizontal punching plate 47, and the material plate suction cup 8 is connected below the negative pressure connector 48.

[0034] The X-axis multi-moving sub linear module 7 with three sets of moving sub-slides is used for collaborative handling. As Figure 1 shown, the X-axis multi-moving sub linear module 7 is sequentially provided with a first moving sub 71, a second moving sub 72, and a third moving sub 73 from right to left. The loading and unloading table 9 on the right side serves as a feeding table for providing the PCB material plates to be processed. Rectangular PCBs 100 are stacked on the feeding table, and gold fingers are designed on both opposite sides of each PCB 100. Each PCB 100 is separated by spacer paper. The X-axis multi-moving sub linear module 7 is erected on the machine table 1 through a gantry, and a color sensor 200 is installed on the gantry. The color sensor 200 faces the tabletop of the loading and unloading table 9 and is used to distinguish and judge the PCB 100 or the spacer paper.

[0035] As Figure 1 shown, the milling stations 2 are sequentially defined as a first station 2a and a second station 2b from right to left in the figure. The device takes out the recognized PCB 100 from the loading and unloading table 9 through the material plate suction cup 8 on the first moving sub 71 and transports it to the first bracket 15 and the second bracket 16 at the first station 2a. At the first station 2a, the plate clamp 17 on the Y-axis linear module 13 flips along the rotating shaft 31 under the drive of the motor 34 and presses the PCB 100 against the first bracket 15. Subsequently, the Y-axis linear module 13 feeds the PCB 100 into the milling spindle 14 as Figure 4 shown for chamfering. After the processing is completed, the Y-axis linear module 13 resets and the plate clamp 17 is unlocked.

[0036] Since the gold fingers on the first side of the PCB 100 have been milled at the first workstation 2a, in order to mill the gold fingers on the second side of the PCB 100 at the second workstation 2b, it is necessary to change the direction of the PCB 100 at the transfer platform 3. For this purpose, the board suction cup 8 on the second mover 72 takes out the PCB 100 and transports it to the transfer platform 3 as shown in Figure 2 . The PCB 100 covers the board rotating table 4, and the board rotating table 4 provides negative pressure to hold the PCB 100 and rotates 180 degrees under the drive of the rotating cylinder 43, so that the gold fingers on the second side face the milling spindle 14. To further solve the offset problem caused by rotation, the guiding push arm 6 pushes and corrects the PCB 100 towards the reference frame 39 under the drive of the cylinder slide. Thereafter, the Y-axis linear module 13 at the second workstation 2b performs milling chamfering in the same way. Finally, the board suction cup 8 on the third mover 73 transports the PCB 100 to Figure 1 the loading and unloading table 9 at the left position for unloading.

[0037] Since there are spacer papers stacked on the loading and unloading table 9 which serves as the feeding table at the Figure 1 right position, it is necessary to use the first mover 71 and the third mover 73 on the X-axis multi-mover linear module 7 to transport the spacer papers. First, the first mover 71 sucks the spacer papers to the transfer platform 3, and then the third mover 73 transports the spacer papers on the transfer platform 3 to Figure 1 the loading and unloading table 9 at the left position which serves as the receiving table. In this way, the reuse of the spacer papers can be realized.

[0038] In addition, a metal sensor can be additionally mounted on the horizontal punching plate 47, which can cooperate with the color sensor 200 to realize the secondary verification of the PCB 100 board and improve the recognition reliability.

[0039] The X-axis multi-mover linear module 7 has three sets of mover sliders, which can cooperate to realize the milling processing of the gold finger chamfer and the reuse of the spacer papers.

[0040] In addition, a high-speed barcode scanner 300 is also provided on the first mover. Through the coordinated movement of the Y-axis linear module 13 and the moving mover, it quickly locates the product QR code position. By identifying the product QR code and binding the production information, the product can be traced.

[0041] In summary, the present utility model provides a board milling processing interval variable position transfer device, which realizes the variable position switching of the gold fingers of the PCB 100 between the milling workstations through the transfer platform 3, and uses three sets of mover sliders to cooperate to realize the board milling delivery and the exchange and reuse of the spacer papers. At the same time, a secondary verification method is adopted to improve the reliability of the whole machine, thereby greatly improving the transfer efficiency of the PCB 100 milling processing process.

[0042] The above are only the embodiments of the present utility model, and thus do not limit the patent scope of the present utility model. Any equivalent structure or equivalent process transformation made by using the content of the specification of the present utility model, or directly or indirectly applied in other related technical fields, shall similarly be included within the patent protection scope of the present utility model.
