[0024] It should be noted that multiple groups of grooves (not shown in the figure) for placing products are symmetrically provided on the mold base 6. The three-axis moving device 2 drives the double-station screw locking assembly 3 to move along the X, Y, and Z axes. The three-axis moving device 2 drives the double-station screw feeding assembly 4 to move along the X and Y axes. The two-axis moving device 7 drives the U-shaped frame 8 to move along the Y and Z axes.

[0025] The conveying assembly 5 conveys the mold base 6 and stops when the products on both sides of the mold base 6 correspond to the front end position of the U-shaped frame 8. The two-axis moving device 7 drives the front end of the U-shaped frame 8 to press the centers of the products on both sides. Then, the three-axis moving device 2 drives the double-station screw locking assembly 3 and the double-station screw feeding assembly 4 to perform screw locking processing on the products. After the processing is completed, the mold base 6 is continuously conveyed by the conveying assembly 5.

[0026] Please refer to Figure 6 , the conveying assembly 5 includes a frame body 51. Two groups of guide wheel bars 52 are symmetrically installed in the grooves at the top of the frame body 51. A chain drive 57 is installed at the front top of the frame body 51. A plurality of roller shafts 54 are rotatably connected through the inside of the chain drive 57 at equal intervals. A conveyor belt 55 is connected to the outside of the plurality of roller shafts 54. A plurality of mold bases 6 are distributed at equal intervals between the two groups of guide wheel bars 52 and the conveyor belt 55. A servo motor 56 is installed at one end of the frame body 51. The output end of the servo motor 56 is connected to the front ends of the plurality of roller shafts 54 through the chain drive 57.

[0027] It should be noted that the conveyor belt 55 is located above the front guide wheel bar 52. Through the chain drive 57, the servo motor 56 drives the plurality of roller shafts 54 to rotate synchronously. Then, the plurality of roller shafts 54 drive the conveyor belt 55 to work, place the mold base 6 on one end of the two groups of guide wheel bars 52 and slide it to the lower part of the starting end of the conveyor belt 55 for conveying the mold base 6 by the conveyor belt 55.

[0028] Please refer to Figure 4 , the double-station screw locking assembly 3 includes two groups of adjusting plates 34. A first cylinder 35 is installed on one side of each group of adjusting plates 34. The telescopic end of each first cylinder 35 is connected to a lifting plate 36. A driving motor 37 is installed at the front end of the lifting plate 36. The output end of the driving motor 37 is connected to a bit 38. A negative pressure cylinder 39 is installed at the bottom of each group of adjusting plates 34 and outside each group of bits 38. A fixing plate 31 is arranged at the rear side of the two groups of adjusting plates 34. A cross bar 32 is installed at the front end of the fixing plate 31. Two sliding sleeves 33 are slidably connected to the outside of the cross bar 32. And each sliding sleeve 33 and each cross bar 32 are fixedly connected by bolts. The two sliding sleeves 33 are connected to the two groups of adjusting plates 34. The rear side of the fixing plate 31 is connected to the moving end of the upper Z-axis moving component.

[0029] It should be noted that an air extraction hole is provided on one side of the negative pressure cylinder 39. The air extraction hole is connected to an external negative pressure device. A sealing ring is provided at the top of the negative pressure cylinder 39 and outside the bit 38. When the bottom of the negative pressure cylinder 39 is located outside the screw, the negative pressure cylinder 39 adsorbs the head of the screw, thereby driving the motor 37 to drive the bit 38 to rotate. The first cylinder 35 drives the lifting plate 36, the driving motor 37 and the bit 38 to perform lifting movements, and then the screw at the bottom of the negative pressure cylinder 39 is fixed on the product.

[0030] Please refer to Figure 5 , the double-station screw feeding assembly 4 includes a rear side plate 41. Two groups of second cylinders 42 are symmetrically installed at the front end of the rear side plate 41. Bracket 43 is installed at the telescopic end of the two groups of second cylinders 42. Brackets 46 are installed at both ends of the rear side plate 41. Guide cylinders 47 are installed at the front end of each group of brackets 46. The outlet ends of each group of guide cylinders 47 correspond to the front ends of each group of brackets 43 in position. The rear end of the rear side plate 41 is connected to the bottom of the upper Z-axis moving assembly. The rear ends of the rear side plate 41 and the two groups of brackets 43 are slidably connected.

[0031] It should be noted that the tops of the two groups of guide cylinders 47 are connected to an automatic screw feeder through hoses. The screws enter the guide cylinders 47 and fall on the front ends of the brackets 43. The second cylinder 42 drives the brackets 43 to move left and right, thereby transporting the screws at the front ends of the brackets 43 directly below the negative pressure cylinder 39.

[0032] The working principle of the present utility model: When in use, first, the servo motor 56 drives the multiple groups of roller shafts 54 to rotate synchronously through the chain drive 57. Further, the multiple groups of roller shafts 54 drive the conveyor belt 55 to work. Place the mold base 6 at one end of the two groups of guide wheel bars 52 and slide it to the starting end of the conveyor belt 55 for conveying. Then, the conveyor belt 55 conveys the mold base 6. When the products on both sides of the mold base 6 correspond to the front end of the U-shaped frame 8 in position, stop. The double-axis moving device 7 drives the front end of the U-shaped frame 8 to press the centers of the two products.

[0033] Then, the automatic screw feeder transports the screws to the guide cylinders 47 and they fall on the front ends of the brackets 43. The second cylinder 42 drives the brackets 43 to move left and right, thereby transporting the screws at the front ends of the brackets 43 directly below the negative pressure cylinder 39. The three-axis moving device 2 cooperates with the double-station screw locking assembly 3 to move. Further, the bottom of the negative pressure cylinder 39 moves outside the screw. The negative pressure cylinder 39 adsorbs the head of the screw. Then, move the negative pressure cylinder 39 and the screw to the product processing position to be processed. Thereby, the driving motor 37 drives the bit 38 to rotate. The first cylinder 35 drives the lifting plate 36, the driving motor 37 and the bit 38 to perform lifting movements, and then the screw at the bottom of the negative pressure cylinder 39 is fixed on the product. In this way, the three-axis moving device 2 cooperates with the double-station screw locking assembly 3 and the double-station screw feeding assembly 4 to process two groups of products synchronously, increasing production efficiency. After processing, the mold base 6 is continuously conveyed by the conveying assembly 5.
