[0023] In use, the connecting assembly 21 is provided with four, which are equidistantly installed at the front and rear of the replacement frame 203, as shown in Figure 1 and Figure 2 The four replacement plates 211 are installed in the inner part of the replacement frame 203 through the four connecting assemblies 21. The first pressing head 213, the second pressing head 214, the third pressing head 215 and the fourth pressing head 216 correspond to different shapes of lampshades, as shown in Figure 7As shown, respectively corresponding to spherical lampshade, cylindrical lampshade, rectangular lampshade and modular square combination lampshade. When the need to replace different lampshade, through the PLC controller 302 start motor 206, through the motor 206 output end of the rotation driven shaft 207 rotation, while driving gear 205 rotation, further drive the tooth plate 204 in the corresponding rack 201 inside the mobile, thus driving the replacement frame 203 in the fixed rod 202 surface movement.

Then start two second cylinder 402, push the separation plate 403 down, at this time, two wedge block 404 down into the corresponding push-pull clamp 2111 inside, with the continuous movement of wedge block 404, its inclined surface will produce horizontal thrust on the push-pull clamp 2111 while moving down, so that two push-pull clamp 2111 move outward at the same time, then drive two moving block 2109 outward, and gradually slide out from the slide hole 210 inside. With the outward movement of the moving block 2109, drive the support block 2112 on the outer surface of the limiting rod 2113 sliding, pull the connection spring 2114 unfolding.The moving block 2109 moves while driving the second magnet 2110 to move, so that the distance between the second magnet 2110 and the first magnet 2107 gradually increases, the same polarity magnetism disappears, the repulsive force received by the first magnet 2107 disappears from strong to weak, and the pushing force received by the reset spring 2104 gradually decreases.

When the conveyor 1 pauses, the pressing head is quickly replaced, and then the conveyor 1 resumes work and continues to convey the pre-installed lamp body and lampshade. When it is conveyed below the pressing mechanism 3, the conveyor 1 pauses the conveying, the first air cylinder 303 is started, the rotating mechanism 304 and the rotating block 305 are pushed downward, and the connecting pressing head is pushed downward, so that the lampshade is forced to press and buckle on the lamp body, thereby completing the automatic buckling processing of the lampshade and the lamp body.

[0024] Example two: as Figures 4-5 and Figures 8-10As shown, the top of the conveyor 1 is provided with an automatic replacement mechanism 2 for replacing different pressure heads, the top of the automatic replacement mechanism 2 is provided with a pressing mechanism 3 for buckling the lamp cover and the lamp body, the bottom of the pressing mechanism 3 is provided with a separation mechanism 4, the connecting assembly 21 comprises two connecting blocks 2101, the outer surfaces of the two connecting blocks 2101 are both fixedly provided with two clamping blocks 2102, the inner walls of the two connecting blocks 2101 are both fixedly provided with reinforcing rods 2103, one end of each of the two reinforcing rods 2103 is fixedly provided with a moving plate 2106, the inside of each of the two moving plates 2106 is provided with a first magnet 2107, the outer surface of each of the two moving plates 2106 is provided with a moving block 2109, the inside of each of the two moving blocks 2109 is provided with a second magnet 2110, the edge of the outer surface of each of the two moving plates 2106 is fixedly provided with a limiting clamp 2108, the outer surface of each of the two reinforcing rods 2103 is movably sleeved with a reset spring 2104, the inside of each of the two moving blocks 2109 is fixedly provided with a pushing clamp 2111, the outer surface of each of the two moving blocks 2109 is fixedly provided with two supporting blocks 2112, the inside of each of the four supporting blocks 2112 is movably embedded with two limiting rods 2113, the separation mechanism 4 comprises a separation frame 401, the bottom of the separation frame 401 is fixedly provided with two second air cylinders 402, the output ends of the two second air cylinders 402 are fixedly provided with a separation plate 403, the bottom of the separation plate 403 is fixedly provided with two wedge-shaped blocks 404, the two sides of the bottom of the separation plate 403 are both fixedly provided with two limiting triangular frames 405, the top of the separation frame 401 is fixedly arranged in the inside of the pressing frame 301, the front surface and the rear surface of the top of the replacement frame 203 are both provided with a plurality of insertion holes 218, and the outer surface of the first air cylinder 303 is located in the inside of the separation frame 401 and the separation plate 403.

[0025] In this embodiment, when the pressure head is replaced, the connecting assembly 21 is separated from the replacement plate 211 by the separation mechanism 4. As the separation plate 403 moves downward, the wedge block 404 enters the inside of the push clip 2111, and the limiting triangular frame 405 gradually passes through the insertion hole 218 and enters the inside of the replacement frame 203. When the reset spring 2104 pulls the connecting block 2101 to move, it will move the reinforcing rod 2103 together, push the moving plate 2106 and the two limiting clips 2108 to move together, so that the limiting clip 2108 gradually moves to the position below the limiting triangular frame 405. When the second air cylinder 402 is automatically closed, the inside of the push clip 2111 is in contact with the uppermost side of the wedge block 404, and the bottom end of the limiting triangular frame 405 is inserted into the inside of the corresponding limiting clip 2108. The wedge block 404 limits the push clip 2111, and the limiting triangular frame 405 limits the limiting clip 2108, thereby improving the stability of the moving block 2109 and the connecting block 2101 after moving. It prevents the reset spring 2104 or the connecting spring 2114 from accidentally shaking during the subsequent lampshade and lamp body pressing process, causing the connecting block 2101 to move, pushing the clamping block 2102 to the middle of the replacement frame 203, and affecting the upward movement of the subsequent replacement plate 211.

[0026] Figure 11 The manual separation tool in the middle is the same as the main structure in the separation mechanism 4, including the separation plate 403, the wedge block 404 and the limiting triangular frame 405. When the first pressing head 213, the second pressing head 214, the third pressing head 215 or the fourth pressing head 216 of different sizes needs to be replaced, the manual separation tool is used to move above the corresponding pressure head and connecting assembly 21, and then the separation plate 403 is moved downward, so that the wedge block 404 moves downward and gradually enters the corresponding push clip 2111. The process of separating the connecting assembly 21 and the replacement plate 211 is the same as described above. Since the replacement plate 211 is not connected to the pressing mechanism 3, when the connecting assembly 21 is separated from the replacement plate 211, the pressure head can be directly taken out from the inside of the replacement frame 203, then the pressure head of different sizes is replaced and installed back into the replacement frame 203. In this way, other pressure heads of different sizes can be replaced without affecting the processing.

[0027] The effect and working principle of the whole mechanism are as follows: the motor 206 is started by the PLC controller 302 to drive the rotating shaft 207 and the gear 205 to rotate, so that the toothed plate 204 drives the replacement frame 203 to move, and further drives the four replacement plates 211, the first pressing head 213, the second pressing head 214, the third pressing head 215 and the fourth pressing head 216 to move together. When the target pressing head moves to the position directly below the rotating mechanism 304, the motor 206 is automatically turned off, and the replacement frame 203 stops moving. The first cylinder 303 is started to drive the rotating mechanism 304 to move downward by a small distance and then is automatically turned off, and then the rotating mechanism 304 is started to drive the rotating block 305 to rotate, so that the four arc-shaped inserting rods 306 are rotated into the four inserting blocks 217, thereby connecting the replacement plate 211 and the rotating mechanism 304 together, i.e. connecting the target pressing head and the pressing mechanism 3 together, and the replacement of different pressing heads is completed. The two second cylinders 402 are started to drive the separation plate 403 to move downward, at this time, the two wedge-shaped blocks 404 move downward into the inside of the push clamp 2111 and generate a horizontal pushing force on the push clamp 2111, so that the two moving blocks 2109 and the second magnet 2110 move outward, the repulsion force on the first magnet 2107 disappears from strong to weak, the return spring 2104 slowly contracts to pull the connecting block 2101 to move, so that the clamping block 2102 is pulled out of the inserting block 217, and the reinforcing rod 2103 is also moved together to drive the moving plate 2106 and the two limiting clamps 2108 to move together, so that the limiting clamps 2108 gradually move to the position below the limiting triangular frame 405. When the second cylinder 402 is automatically turned off, the inside of the push clamp 2111 is in contact with the uppermost side of the wedge-shaped block 404, and the bottom end of the limiting triangular frame 405 is inserted into the inside of the limiting clamp 2108. After the lampshade is pre-installed on the lamp body and is placed on the conveying belt of the conveyor 1, when it is conveyed to the position below the pressing mechanism 3, the conveyor 1 is paused to convey, the first cylinder 303 is started to drive the rotating mechanism 304 and the rotating block 305 to move downward, and the pressing head moves downward to press the lampshade to be buckled on the lamp body, thereby completing the automatic buckling processing of the lampshade and the lamp body.
