Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0025] Please refer to the following: Figures 1 to 6 As shown, Figure 1 A schematic diagram of the light bulb tightening device 100; Figure 2 for Figure 1 Enlarged structural diagram at point A in the middle; Figure 3 A schematic diagram of the structure of the turntable 203 for the light bulb screwing device 100; Figure 4 for Figure 3 Enlarged structural diagram at point B; Figure 5 A schematic diagram of the light bulb screwing assembly 30 of the light bulb screwing device 100; Figure 6 A schematic diagram of the unloading clamping assembly 40 of the bulb screwing device 100.

[0026] This utility model provides the following technical solution: a light bulb screwing device 100, comprising: a base 10; a turntable 203 rotatably disposed on the base 10, wherein a plurality of receiving seats 2031 are distributed in a ring on the turntable 203; a light bulb screwing assembly 30 disposed on the base 10 and corresponding to the feeding end of the turntable 203; a first clamping cylinder 50 fixedly located above the turntable 203 and corresponding to the receiving seat 2031 moved to the feeding end of the turntable 203; and a discharging clamping assembly 40 disposed on the base 10 and corresponding to the discharging end of the turntable 203.

[0027] This light bulb screwing device 100 is used to assemble a light string 200 in the prior art. The light string 200 is composed of a wire harness 2001, a number of lamp holders 2002 and a number of light bulbs 2003. The wire harness 2001 is connected to each lamp holder 2002 in sequence, and each lamp holder 2002 is threaded with a light bulb 2003.

[0028] In the bulb screwing device 100 provided in this embodiment, when assembling the light string 200, the turntable 203 rotates. A worker, positioned on one side of the turntable 203, manually places the lamp holders 2002 connected to the wire harness 2001 into the respective receiving seats 2031 of the turntable 203. During the rotation of the turntable 203, the lamp holders 2002 in each receiving seat 2031 move sequentially to the loading end to receive the bulb screwing assembly 30 for the bulb screwing process. When the lamp holder 2002 in the receiving seat 2031 at the loading end of the turntable 203 receives the bulb screwing, the first clamping cylinder 50 clamps and fixes the lamp holder 2002, and then the bulb screwing assembly 30 is screwed on. The first clamping cylinder 50 is used to pick up the light bulb 2003 from the outside and screw it onto the lamp holder 2002 in the receiving seat 2031 that moves to the loading end of the turntable 203. After the light bulb 2003 is screwed onto the lamp holder 2002 in the receiving seat 2031 that moves to the loading end of the turntable 203, the lamp holder 2002 is released by the first clamping cylinder 50. The turntable 203 continues to rotate, driving the lamp holder 2002 with the light bulb 2003 screwed onto it in the receiving seat 2031 to the unloading end for the unloading clamping assembly 40 to clamp and unload it. According to the above steps, the light bulbs 2003 are screwed onto each lamp holder 2002 connected to the wire harness 2001 in sequence, so as to assemble the whole light string 200. In this utility model, the turntable 203 drives the lamp holders 2002 connected to each wire harness 2001 to sequentially accept the lamp bulb assembly 30 in the process of screwing in the lamp bulb 2003, and the turntable 203 drives each lamp holder 2002 with the screwed-in lamp bulb 2003 to accept the clamping and unloading of the unloading clamping assembly 40, so as to realize a high-efficiency lamp string 200 assembly production process and effectively save a large part of the labor cost.

[0029] In some embodiments, a drive motor 201 is provided at the bottom of the base 10, and a reduction gearbox 202 is provided at the top of the base 10. The output end of the drive motor 201 is connected to the input end of the reduction gearbox 202. The turntable 203 is rotatably connected to the output end of the reduction gearbox 202. A mounting plate 2021 is fixedly connected to the outer shell of the reduction gearbox 202. The mounting plate 2021 is located in the middle of the turntable 203. The first clamping cylinder 50 is installed on the mounting plate 2021.

[0030] In specific implementation: the drive motor 201 drives the gearbox 202, and the gearbox 202 drives the turntable 203 to rotate, so that the turntable 203 can rotate to drive the lamp holders 2002 in each of the accommodating seats 2031 in turn to receive the lamp 2003 screwing process of the lamp assembly 30, and to drive the lamp holders 2002 with the lamp 2003 screwed in in each of the accommodating seats 2031 in turn to receive the clamping and unloading of the unloading clamping assembly 40. Because a mounting plate 2021 is fixedly connected to the outer shell of the gearbox 202, and the mounting plate 2021 is located in the middle of the turntable 203, the mounting plate 2021 does not move with the turntable 203. This allows the turntable 203 to ensure that the first clamping cylinder 50 always corresponds to each receiving seat 2031 that moves sequentially to the loading end of the turntable 203, thereby clamping and fixing the lamp holder 2002 in the receiving seat 2031 for screwing the bulb assembly 30 onto the bulb 2003. With this arrangement, the drive motor 201 can effectively drive the turntable 203 to rotate, and the mounting plate 2021 can support the first clamping cylinder 50, so that the first clamping cylinder 50 can maintain a fixed position to always correspond to the receiving seat 2031 that moves sequentially to the loading end of the turntable 203.

[0031] In some embodiments, the light bulb screwing assembly 30 includes a first linear module 301, a second linear module 302, a screwing motor 303, and a suction cylinder 304. The first linear module 301 is drivenly connected to the second linear module 302, the second linear module 302 is drivenly connected to the screwing motor 303, the suction cylinder 304 is connected to the output end of the screwing motor 303, and the suction cylinder 304 is connected to an air source.

[0032] In specific implementation: When the bulb assembly 30 picks up the bulb 2003 from the outside and screws it onto the lamp holder 2002, the first linear module 301 drives the second linear module 302 to move outward toward the base 10. Then, the second linear module 302 drives the suction cylinder 304 to descend and pick up the bulb 2003. After that, the second linear module 302 drives the suction cylinder 304 to rise. Then, the first linear module 301 drives the second linear module 302 to move toward the turntable 203. Then, the second linear module 302 drives the suction cylinder 304 to descend and bring the bulb 2003 against the lamp holder 2002. Then, the tightening motor 303 drives the suction cylinder 304 to rotate. When the suction cylinder 304 rotates, it abuts the bulb 2003, causing the bulb 2003 to rotate and be screwed onto the lamp holder 2002. With this configuration, the bulb screwing assembly 30 can effectively pick up the bulb 2003 from the outside and screw the bulb 2003 onto the lamp holder 2002.

[0033] In some embodiments, each receiving base 2031 is provided with a receiving groove 20311, which is used to receive the lamp holder 2002 of the light string 200.

[0034] In practice: the worker can place each lamp holder 2002 connected to the wire harness 2001 into the receiving groove 20311 of each receiving seat 2031 in sequence. With this arrangement, the receiving seat 2031 can receive the lamp holder 2002 through the receiving groove 20311, which can prevent the lamp holder 2002 from falling off the receiving seat 2031 when it is driven by the turntable 203.

[0035] In some embodiments, the unloading clamping assembly 40 includes a linear cylinder 401, a lifting cylinder 402, and a second clamping cylinder 403. The linear cylinder 401 is connected to the lifting cylinder 402 in a transmission manner, and the second clamping cylinder 403 is connected to the output end of the lifting cylinder 402.

[0036] In specific implementation: When the unloading clamping assembly 40 clamps and unloads the lamp holder 2002 with the bulb 2003 screwed on, the linear cylinder 401 drives the lifting cylinder 402 to move towards the turntable 203. Then, the lifting cylinder 402 drives the second clamping cylinder 403 to descend. When the second clamping cylinder 403 descends, it clamps the lamp holder 2002 with the bulb 2003 screwed on on the turntable 203. Then, the lifting cylinder 402 drives the second clamping cylinder 403 to rise. Then, the linear cylinder 401 drives the lifting cylinder 402 to move towards the outside of the base 10. Finally, the second clamping cylinder 403 releases the lamp holder 2002 with the bulb 2003 screwed on. With this setting, the unloading clamping assembly 40 can effectively clamp and unload the lamp holder 2002 with the bulb 2003 screwed on.

[0037] In some embodiments, the base 10 is provided with a controller 60, and the controller 60 integrates a plurality of control buttons 601.

[0038] In practice: the controller 60 is used to control the operation of the light bulb screwing device 100, and the control buttons 601 on the controller 60 are for user operation. This configuration allows the light bulb screwing device 100 to be conveniently controlled via the controller 60.

[0039] In some embodiments, a support rod 101 is provided on the base 10, the support rod 101 corresponds to the feeding end of the turntable 203, and the bulb screw assembly 30 is fixedly installed on the support rod 101.

[0040] In practice: the support rod 101 is used to fix the bulb screwing assembly 30 so that the bulb screwing assembly 30 is stably aligned with the feeding end of the turntable 203, thereby picking up the external bulb 2003 and screwing it onto the lamp holder 2002. This arrangement ensures that the bulb screwing assembly 30 can be stably installed.

[0041] In some embodiments, a support frame 102 is provided on the base 10, the support frame 102 corresponds to the unloading end of the turntable 203, and the unloading clamping assembly 40 is fixedly installed on the support frame 102.

[0042] In practice: the support frame 102 is used to fix the unloading clamping assembly 40 so that the unloading clamping assembly 40 is stably aligned with the unloading end of the turntable 203, thereby clamping and unloading the lamp holder 2002 on the turntable 203 with the bulb 2003 screwed on. This arrangement ensures that the unloading clamping assembly 40 can be stably installed.
