As the market's requirements for the aesthetics of mobile phone appearance continue to increase, manufacturers are committed to etching various exquisite texture patterns on the mobile phone middle frame to enhance product competitiveness and user experience. In order to achieve this goal, spraying photoresist has become one of the key processes, which not only directly affects the aesthetics of the final product, but also is related to production efficiency and cost control.

[0003] At present, in the process of photoresist spraying of mobile phone middle frames, commonly used methods include manual spraying and semi-automatic spraying. Manual spraying mainly depends on the operator's experience and technical level, which is suitable for small-scale customized production, but it is difficult to ensure the uniformity and stable quality of the coating. Semi-automatic spraying is assisted by simple mechanical equipment, which can improve work efficiency to a certain extent, but it is still subject to the instability of manual work. Both manual spraying and semi-automatic spraying will result in high labor intensity and low efficiency, and the coating quality fluctuates greatly, which cannot meet the high-precision uniformity requirements. This problem needs to be solved urgently. Summary of the invention

The blocking component 12 is arranged at a position of the feeding conveying component 11 corresponding to the material picking position of the first transfer mechanism 5 to block the mobile phone middle frame from continuing to be conveyed, so as to facilitate the subsequent material picking operation of the first transfer mechanism 5.

[0036] Reference Figure 2 The feeding conveying assembly 11 includes a feeding conveying frame 111, a feeding conveying belt 112, a feeding conveying roller 113 and a feeding driving member. The feeding conveying frame 111 is arranged on one side of the four-station rotating mechanism 2. There are two feeding conveying rollers 113. The two feeding conveying rollers 113 are horizontally rotatably connected to the head and tail ends of the feeding conveying frame 111 in the horizontal direction, and the two feeding conveying rollers 113 are arranged in parallel. The feeding conveying belt 112 surrounds the two feeding conveying rollers 113. The feeding driving member is arranged at one end of the feeding conveying frame 111 to drive the feeding conveying rollers 113 to rotate. In this embodiment, the loading drive member is configured as a loading drive motor 114, which is horizontally fixedly connected to one end of the loading conveyor frame 111, and a loading conveyor roller 113 is coaxially fixedly connected to the output shaft of the loading drive motor 114. The rotation of the output shaft of the loading drive motor 114 drives the loading conveyor roller 113 to rotate, and the loading conveyor roller 113 rotates to drive the loading conveyor belt 112 to transport, thereby driving the mobile phone middle frame placed on the loading conveyor belt 112 to transport.

[0037] Reference Figure 2 When the mobile phone middle frame is transported to the material taking position of the first transfer mechanism 5, the blocking component 12 prevents the mobile phone middle frame from continuing to be transported backward. Specifically, the blocking component 12 includes a baffle 121 and a blocking driving member 122. The baffle 121 is vertically located at the position of the loading conveyor frame 111 corresponding to the material taking position of the first transfer mechanism 5. The blocking driving member 122 is arranged on the loading conveyor frame 111 to drive the baffle 121 to move vertically up and down. In this embodiment, the blocking driving member 122 includes a support frame 1221 and a blocking cylinder 1222.

The piston rod of the blocking cylinder 1222 is vertically arranged downward, and the baffle 121 is vertically fixedly connected to the end of the piston rod of the blocking cylinder 1222. The piston rod of the blocking cylinder 1222 is stretched to drive the baffle 121 to move vertically downward, thereby achieving the blocking of the mobile phone middle frame.

[0038] Reference Figure 2When the baffle 121 blocks the mobile phone middle frame at the material picking position of the first transfer mechanism 5, the first transfer mechanism 5 transfers the mobile phone middle frame from the feeding conveyor belt 112 to the four-station rotating mechanism 2.

[0039] Reference Figure 1 and Figure 2 The first transfer mechanism 5 also includes a CCD detection system (not shown in the figure) for detecting the position of the middle frame of the mobile phone. The CCD detection system uses a conventional visual capture form to detect the position of the middle frame of the mobile phone, and the CCD detection system is electrically connected to the first manipulator 51. After the CCD detection system captures the position of the middle frame of the mobile phone, it feeds back to the first manipulator 51. The first manipulator 51 adjusts its action according to the received information to accurately transfer the middle frame of the mobile phone to the four-station rotating mechanism 2, which is beneficial to improve the stability and accuracy of subsequent spraying operations.

The support plate 2211 is rotatably connected to the rotating seat 21 through the central axis 8. The gear 2223 is fixedly sleeved on the central axis 8. The rack 2222 is meshed with the gear 2223. The adjusting cylinder 2221 is fixedly arranged on the rotating seat 21 to drive the rack 2222 to move back and forth. The extension and contraction of the piston rod of the adjusting cylinder 2221 drives the rack 2222 to move back and forth, so that the rack 2222 drives the gear 2223 to rotate back and forth, thereby realizing the flipping action of the support plate 2211 driven by the central axis 8.

[0044] Reference Figure 1 and Figure 3 The spraying mechanism 3 includes a second manipulator 31 and a spray head 32. The second manipulator 31 is located at one side of the rotating seat 21. The spray head 32 is arranged at the end of the second manipulator 31 for spraying the middle frame of the mobile phone.

[0045] Reference Figure 4 When the spraying operation of the mobile phone middle frame is completed, the second transfer mechanism 6 transfers the mobile phone middle frame after the spraying operation to the unloading mechanism 4. Specifically, the second transfer mechanism 6 includes a third manipulator 61 and a second suction cup 62. The third manipulator 61 is located between the rotating seat 21 and the unloading mechanism 4. The second suction cup 62 is arranged at the end of the third manipulator 61. The action of the third manipulator 61 transfers the mobile phone middle frame after the spraying operation to the unloading mechanism 4 through the second suction cup 62.

In this embodiment, the unloading drive member is configured as a unloading drive motor 44, which is horizontally fixedly connected to one end of the unloading conveying frame 41, and a unloading conveying roller 43 is coaxially fixedly connected to the output shaft of the unloading drive motor 44. The rotation of the output shaft of the unloading drive motor 44 drives the unloading conveying roller 43 to rotate, and the unloading conveying roller 43 rotates to drive the unloading conveyor belt 42 to transport, thereby driving the middle frame of the mobile phone transferred to the unloading conveyor belt 42 to be transported backward.

[0047] The implementation principle of a spraying machine for processing a mobile phone middle frame in an embodiment of the present application is as follows: when it is necessary to spray the mobile phone middle frame, the mobile phone middle frame is placed on the loading conveyor belt 112 for conveying, and when the mobile phone middle frame is conveyed to the material picking position of the first transfer mechanism 5, the baffle 121 blocks the mobile phone middle frame, and then the first manipulator 51 moves the mobile phone middle frame to the support plate 2211 through the first suction cup 52, and the support plate 2211 fixes the mobile phone middle frame through the suction hole 7 and the vacuum suction system, and then the rotating seat 21 rotates 90°, so that the fixed mobile phone middle frame enters the spraying mechanism 3, and the second manipulator 31 in the spraying mechanism 3 sprays the mobile phone middle frame through the nozzle 32 Operation, and by adjusting the cooperation of the cylinder 2221, the rack 2222 and the gear 2223 to flip the support plate 2211 to adjust the posture of the mobile phone middle frame, so as to quickly switch the spraying operation on different surfaces. After the spraying operation is completed, the rotating seat 21 continues to rotate 90°, and the action of the third manipulator 61 transfers the mobile phone middle frame after the spraying operation to the unloading conveyor belt 42 through the second suction cup 62 for unloading and conveying operation. During the entire spraying process of the mobile phone middle frame, there is no need for manual operation by the operator, and the degree of automation is high, which reduces the labor intensity of the operator and improves the production efficiency. The spraying is uniform, and the coating quality fluctuation is small, which is conducive to improving the production accuracy of the product.
