Similarly, Figure 6 As shown, when the clamping assembly on the right is performing press-assembly of the bottom shell 4 and the lamp shade 3, the clamping assembly on the left is performing clamping of the base; the screw rod 7 synchronously realizes the movement of the two clamping assemblies, but the two clamping assemblies perform press-assembly and clamping actions respectively, the clamping action is used for the preparation of the base, and the press-assembly is used for the installation of the base, the two clamping assemblies are respectively responsible for their own assembly tasks, and do not interfere with each other, the assembly efficiency is improved, and it is capable of handling large-scale lamp assembly operations; after the bottom shell 4 is pressed on the lamp shade 3, it is transported away from the assembly equipment under the transmission of the conveyor belt 1.

The setting of the support plate 8 can adapt to the situation where the lamp beads protrude from the end surface of the bottom shell 4. At the same time, the movement of the base can be constrained by the lamp beads cooperating with the yielding opening 9, thereby improving the stability of the base; the grabbing component can grab the bottom shell 4 on the support plate 8 close to the truss 5. After grabbing one of the bottom shells 4 on the support plate 8, the subsequent bottom shell 4 fills its place. The bottom shells 4 at both ends of the truss 5 are loaded in this way to ensure that the bottom shell 4 is loaded and the grabbing is carried out smoothly.

[0062] The clamping assembly also includes an expansion mechanism symmetrically arranged on the support plate 8, and the expansion mechanism can guide the two No. 2 clamping rods 12 to be clamped on the bottom shell 4; the screw rod 7 drives the clamping assembly to move, and when the clamping assembly performs the action of clamping the bottom shell 4, the slide plate 10 moves toward the top of the bottom shell 4, and at the same time, the two No. 2 clamping rods 12 gradually approach the expansion mechanism, and the expansion mechanism expands the two No. 2 clamping rods 12 to both sides of the support plate 8, and the No. 2 clamping rod 12 drives the connecting plate 13 to rotate around the No. 1 clamping rod 11. When the No. 2 clamping rod 12 passes over the expansion mechanism, the No. 2 clamping rod 12 is clamped on the bottom shell 4 under the torsion of the torsion spring connected to the connecting plate 13, and the No. 1 clamping rod 11 is also clamped on the bottom shell 4, thereby clamping the bottom shell 4.

[0063] Reference Figure 3 - Fig.18 Each of the expansion mechanisms includes a vertical plate 14, which is fixedly connected to the end position of the support plate 8. A guide plate 15 is fixedly connected to the upper end of the vertical plate 14. The end of the guide plate 15 is tilted to point to the lower middle part of the transmission assembly, and the end of the guide plate 15 is rotatably connected to the wedge plate 16 through a torsion spring. In the initial state, the wedge plate 16 and the guide plate 15 are in a parallel state, and the wedge plate 16 and the guide plate 15 are horizontally located below the slide plate 10; in the process of the two No. 2 clamping rods 12 crossing the expansion assembly, the two No. 2 clamping rods 12 are first squeezed on the connecting plate 13, and then on the wedge Under the extrusion and guidance of the plate 16 and the guide plate 15, the two adjacent No. 2 clamping rods 12 are spread apart from each other. When the No. 2 clamping rod 12 passes over the vertical plate 14, the No. 2 clamping rod 12 loses the expansion of the expansion assembly. Under the torsion force of the torsion spring connected to the connecting plate 13, the No. 2 clamping rod 12 rotates and resets, and is clamped on the bottom shell 4. At the same time, the two No. 1 clamping rods 11 are also clamped on the bottom shell 4. At this time, the clamping assembly clamps the bottom shell 4. During the clamping process of the clamping assembly, the bottom shell 4 on the other clamping assembly has been pressed on the lampshade 3 by the pressing assembly.

[0064] After the clamping assembly clamps the bottom shell 4, the clamping assembly moves toward the top of the conveyor belt 1 under the drive of the transmission assembly. At this time, the two No. 2 clamping rods 12 are squeezed on the wedge plate 16 and squeeze the connecting plate 13 outward. When the two No. 2 clamping rods 12 pass over the connecting plate 13, the connecting plate 13 rotates and resets under the torsion of the torsion spring connected to it, and is in the initial state with the guide plate 15.

[0065] Reference Figure 3 - Fig.13A pressing assembly is arranged above the slide plate 10, and the pressing assembly includes a cylinder 17, the output end of the cylinder 17 passes through a through hole opened in the middle position of the slide plate 10, and a pressing plate 18 is fixedly connected to the output end of the cylinder 17, and the pressing plate 18 can press the bottom shell 4 on the clamping assembly onto the lampshade 3; when the clamping assembly transfers the bottom shell 4 to the top of the conveyor belt, the cylinder 17 drives the pressing plate 18 to press down on the upper end surface of the bottom shell 4 at this time, and at the same time, the lower end of the bottom shell 4 is opposite to the disconnection of the lampshade 3. Under the pressure of the cylinder 17, the elastic sheet part of the bottom shell 4 is embedded in the port of the lampshade 3. At this time, the bottom shell 4 is separated from the No. 1 clamping rod 11 and the No. 2 clamping rod 12, and then the cylinder 17 drives the pressing plate 18 to move up and reset, and the conveyor belt 1 transfers the assembled lamp away from the assembly equipment.

[0066] Reference Figure 3 - Figure 7 ,as well as Fig.19 A pre-pressing assembly is provided between the two conveyor belts 1, and the pre-pressing assembly can press the port of the lampshade 3 in the placement seat 2 into a horizontal shape, and the pre-pressing assembly includes a T-shaped support frame 19, both ends of the support frame 19 extend above the conveyor belt 1, and the horizontal ends of the support frame 19 are slidably connected with a vertical rod 20, the upper end of the vertical rod 20 is connected to the upper surface of the support frame 19 through a spring, and the lower end of the vertical rod 20 is fixedly connected with a flat plate 21;

[0067] A driven plate 22 is also fixedly connected to the vertical rod 20, and the driven plate 22 is located below the horizontal end of the support frame 19. An active plate 23 is matched above the driven plate 22, and the active plate 23 is fixedly connected to the output end of the cylinder 17, and the active plate 23 can move up and down between the lower end surface of the cylinder body of the cylinder 17 and the upper surface of the slide plate 10; the lower surface of the flat plate 21 is parallel to the port of the placement seat 2; due to the shape of the lampshade 3, when the lampshade 3 is placed, the port of the lampshade 3 may not be parallel to the port of the placement seat 2, which will affect the accurate matching of the elastic sheet on the bottom shell 4 and the port of the lampshade 3. For this purpose, a pre-pressing component is provided, which can press the lampshade 3 in each placement seat 2 into place , so that the port of the lampshade 3 is parallel to the lower end of the bottom shell 4 at this time; and the pre-pressing component is executed along with the pressing component. When the pressing component is executed, the cylinder 17 will drive the active plate 23 to move downward, the active plate 23 will press the driven plate 22 downward, and the driven plate 22 will drive the vertical rod 20 to move downward, and the vertical rod 20 drives the flat plate 21 to press down on the port position of the lampshade 3, and press the lampshade 3 into place, ensuring the accurate matching and assembly of the lampshade 3 and the bottom shell 4 in the later stage; after the pre-pressing is completed, that is, the pressing component is executed, the cylinder 17 drives the pressing plate 18 and the active plate 23 to move upward, at this time the vertical rod 20 moves upward and resets under the elastic force of the spring connected to it, and the driven plate 22 also moves upward and resets, and prepares for the pre-pressing of the next lampshade 3.

The push plate 26 is connected to the U-shaped push frame 24 through a torsion spring. When the bottom shell 4 exerts an outward extrusion force on the push plate 26, the push plate 26 can expand outward and pass over a bottom shell 4. When the clamping assembly clamps the bottom shell 4 and moves above the conveyor belt 1, the magnetic force of the magnetic plate 27 attracts the U-shaped push frame 24, and at this time, the U-shaped push frame 24 is driven to move toward the middle of the truss 5. At the same time, the U-shaped push frame 24 drives the push plate 26, and the push plate 26 pushes the bottom shell 4 to move to the end position of the support plate 8, that is, the bottom shell 4 is pushed toward the middle of the truss 5, and the loading and preparation of the bottom shell 4 is completed at this time.

[0070] In the present embodiment, the moving stroke of the clamping assembly is greater than the diameter of the bottom shell 4, and the pushing distance of the push plate 26 each time is the size of the diameter of the bottom shell 4. In order to ensure that the loading and preparation of the bottom shell 4 is smooth and successful, a limit protrusion 25 is set on the horizontal rod above the U-shaped push frame 24. The limit protrusion 25 can constrain the moving stroke of the U-shaped push frame 24, thereby constraining the moving stroke of the push plate 26, so that the push plate 26 moves a stroke of the size of the diameter of the bottom shell 4 each time.

[0071] Reference Fig.14 - Fig.15A straightening plate 28 is provided on the inner side of the rotation connection point between the guide plate 15 and the wedge plate 16, and the straightening plate 28 is fixedly connected to the side wall of the wedge plate 16; the guide plate 15 causes the wedge plate 16 and the guide plate 15 to maintain a horizontal state through the torsion force of the torsion spring, and at the same time, under the constraint of the straightening plate 28, the parallelism of the guide plate 15 and the wedge plate 16 in the initial state can be further ensured, that is, the connecting plate 13 is further constrained so that the connecting plate 13 can only deflect outward but not inward, thereby ensuring that the two No. 2 clamping rods 12 can be effectively supported and expanded.

[0072] Reference Fig.17 A limit block 29 is provided on the upper surface of the driven plate 22, and the limit block 29 can be pressed against the lower surface of the horizontal end of the support frame 19; the limit block 29 is provided on the driven plate 22, which can limit the height of the driven plate 22, so that the plane where the driven plate 22 is located is always lower than the plane where the active plate 23 is located, ensuring that the active plate 23 can be pressed down on the driven plate 22.

[0073] Reference Fig.19 A rubber layer 30 is provided on each of the No. 1 clamping rods 11 and each of the No. 2 clamping rods 12; the rubber layer 30 on the No. 1 clamping rods 11 and the No. 2 clamping rods 12 improves the clamping stability of the No. 1 clamping rods 11 and the No. 2 clamping rods 12 on the bottom shell 4.

[0074] Working principle: In this embodiment, the transmission assembly also includes an operating system and a servo motor. The servo motor is arranged at the middle lower surface position of the truss 5. Under the control of the operating system, the servo motor can drive the screw rod 7 to rotate forward and reverse, thereby driving the clamping assembly to move synchronously back and forth along the window 6;

[0075] The screw rod 7 drives the two clamping components to move synchronously in the same direction. Figure 6 As shown, when the two clamping assemblies are in operation, the left clamping assembly is pressing and assembling the bottom shell 4 and the lampshade 3, and the right clamping assembly is clamping the base. Similarly, Figure 7 As shown, when the clamping assembly on the right is performing press assembly of the bottom shell 4 and the lamp shade 3, the clamping assembly on the left is performing clamping of the base; the screw rod 7 realizes the movement of the two clamping assemblies synchronously, but the two clamping assemblies perform press assembly and clamping actions respectively, the clamping action is used for preparing the base, and the press assembly is used for installing the base, the two clamping assemblies are responsible for their own assembly tasks, and do not interfere with each other, the assembly efficiency is improved, and it is capable of handling large-volume lamp assembly operations; after the bottom shell 4 is pressed on the lamp shade 3, it is transported away from the assembly equipment by the conveyor belt 1;

[0076] The lamp beads are installed on the bottom shell 4, and the lamp beads protrude from the end surface of the bottom shell 4. The support plate 8 can adapt to the situation that the lamp beads protrude from the end surface of the bottom shell 4. At the same time, the movement of the base can be constrained by the lamp beads cooperating with the yielding opening 9, thereby improving the stability of the base. The grabbing assembly can grab the bottom shell 4 on the support plate 8 close to the truss 5. After grabbing one of the bottom shells 4 on the support plate 8, the subsequent bottom shells 4 fill its position. The bottom shells 4 at both ends of the truss 5 are loaded in this way, ensuring that the bottom shell 4 is loaded and the grabbing is carried out smoothly.

[0077] The screw rod 7 drives the clamping assembly to move. When the clamping assembly performs the action of clamping the bottom shell 4, the slide plate 10 moves toward the top of the bottom shell 4. At the same time, the two No. 2 clamping rods 12 gradually approach the expansion mechanism. The expansion mechanism expands the two No. 2 clamping rods 12 to both sides of the support plate 8. The No. 2 clamping rod 12 drives the connecting plate 13 to rotate around the No. 1 clamping rod 11. When the No. 2 clamping rod 12 passes over the expansion mechanism, the No. 2 clamping rod 12 is clamped on the bottom shell 4 under the torsion of the torsion spring connected to the connecting plate 13. At the same time, the No. 1 clamping rod 11 is also clamped on the bottom shell 4, so that the bottom shell 4 is clamped;

[0078] When the two No. 2 clamping rods 12 pass over the expansion assembly, the two No. 2 clamping rods 12 are first squeezed on the connecting plate 13, and then, under the squeezing and guidance of the wedge plate 16 and the guide plate 15, the two adjacent No. 2 clamping rods 12 are spread apart from each other. When the No. 2 clamping rod 12 passes over the vertical plate 14, the No. 2 clamping rod 12 loses the expansion of the expansion assembly. Under the torsion force of the torsion spring connected to the connecting plate 13, the No. 2 clamping rod 12 rotates and resets, and is clamped on the bottom shell 4. At the same time, the two No. 1 clamping rods 11 are also clamped on the bottom shell 4. At this time, the clamping assembly clamps the bottom shell 4. During the clamping process of the clamping assembly, the bottom shell 4 on the other clamping assembly has been pressed on the lampshade 3 by the pressing assembly.

[0079] After the clamping assembly clamps the bottom shell 4, the clamping assembly moves toward the top of the conveyor belt 1 under the drive of the transmission assembly. At this time, the two No. 2 clamping rods 12 are pressed on the wedge plate 16 and press the connecting plate 13 outward. When the two No. 2 clamping rods 12 pass over the connecting plate 13, the connecting plate 13 rotates and resets under the torsion of the torsion spring connected thereto, and is in the initial state with the guide plate 15.

[0080] When the clamping assembly transfers the bottom shell 4 to the top of the conveyor belt, the cylinder 17 drives the pressing plate 18 to press down on the upper end surface of the bottom shell 4 at this time, and at the same time, the lower end of the bottom shell 4 is opposite to the disconnection of the lampshade 3. Under the pressure of the cylinder 17, the elastic sheet part of the bottom shell 4 is embedded in the port of the lampshade 3. At this time, the bottom shell 4 is separated from the No. 1 clamping rod 11 and the No. 2 clamping rod 12, and then the cylinder 17 drives the pressing plate 18 to move up and reset, and the conveyor belt 1 transfers the assembled lamp away from the assembly equipment;

[0081] The lower surface of the flat plate 21 is parallel to the port of the placement seat 2; due to the shape of the lampshade 3, when the lampshade 3 is placed, the port of the lampshade 3 may not be parallel to the port of the placement seat 2, which will affect the accurate matching of the elastic sheet on the bottom shell 4 and the port of the lampshade 3. For this purpose, a pre-pressing component is provided, which can press the lampshade 3 in each placement seat 2 into place, so that the port of the lampshade 3 is parallel to the lower end of the bottom shell 4 at this time; and the pre-pressing component is executed with the execution of the pressing component. When the pressing component is executed, the cylinder 17 will The active plate 23 moves downward, the active plate 23 presses down the driven plate 22, the driven plate 22 drives the vertical rod 20 to move downward, the vertical rod 20 drives the flat plate 21 to press down on the port position of the lampshade 3, and presses the lampshade 3 into place, ensuring the accurate matching and assembly of the lampshade 3 and the bottom shell 4 in the later stage; after the pre-pressing is completed, that is, the pressing assembly is completed, the cylinder 17 drives the pressing plate 18 and the active plate 23 to move upward, at this time the vertical rod 20 moves upward and resets under the elastic force of the spring connected to it, and the driven plate 22 also moves upward and resets, and is ready for the pre-pressing of the next lampshade 3;

[0082] The U-shaped push frame 24 can move back and forth along the upper surface of the truss 5, and in the process of moving back and forth, push the subsequent bottom shell 4 to the end of the support plate 8, that is, the position for the clamping assembly to clamp; when the clamping assembly moves toward the support plate 8, the magnetic plate 27 on the cylinder 17 will push the U-shaped push frame 24 away from the truss 5, and at the same time, the push plate 26 at the end of the horizontal rod below the U-shaped push frame 24 passes over a bottom shell 4. At this time, the push plate 26 is placed between the two adjacent bottom shells 4 in front and behind, and the push plate 26 is connected to the U-shaped push frame 24 through a torsion spring. When the push plates 26 generate an outward extrusion force, the push plates 26 can expand outward and pass over a bottom shell 4; when the clamping assembly clamps the bottom shell 4 and moves toward the top of the conveyor belt 1, the magnetic force of the magnetic plate 27 attracts the U-shaped push frame 24, which drives the U-shaped push frame 24 to move toward the middle of the truss 5. At the same time, the U-shaped push frame 24 drives the push plates 26, which push the bottom shell 4 and move it toward the end position of the support plate 8, that is, push the bottom shell 4 toward the middle of the truss 5. At this time, the loading and preparation of the bottom shell 4 is completed;

[0083] In the present embodiment, the moving stroke of the clamping assembly is greater than the diameter of the bottom shell 4, and the pushing distance of the push plate 26 each time is the size of the diameter of the bottom shell 4. In order to ensure that the loading and preparation of the bottom shell 4 is smooth and successful, a limit protrusion 25 is set on the horizontal rod above the U-shaped push frame 24. The limit protrusion 25 can constrain the moving stroke of the U-shaped push frame 24, thereby constraining the moving stroke of the push plate 26, so that the push plate 26 moves a stroke of the size of the diameter of the bottom shell 4 each time.
