Description

Technical Field

[0001] The utility model relates to the technical field of LED bulb production, in particular to an automatic bulb sealing and exhausting device. Background Technique

[0002] An LED bulb is a solid-state semiconductor device that can convert electrical energy into visible light. It can directly convert electricity into light. It has the characteristics of high efficiency and long life, and can be continuously used for 100,000 hours, which is 100 times longer than that of ordinary incandescent bulbs. During the production process of LED bulbs, the lamp core needs to be sent into a glass tube, and then packaged and exhausted through an automatic sealing and exhausting device.

[0003] The existing Chinese patent with the application number 202221188073.4 discloses an automatic bulb sealing and exhausting device for LED bulb production, including a machine body and a sealing and exhausting mechanism. A control panel is arranged on the front surface of the machine body. An elevating adjustment mechanism is arranged above the interior of the machine body, and a sealing and exhausting mechanism is arranged in the middle of the inner side of the elevating adjustment mechanism. A size adjustment mechanism is arranged below the sealing and exhausting mechanism. For this automatic bulb sealing and exhausting device for LED bulb production, clamping blocks are arranged at the lower ends of the right clamping frame and the left clamping frame, and the clamping blocks are connected by a first support rod, a spring and a second support rod. When placing a larger bulb, the spring stretches, and the right clamping frame and the left clamping frame move outward to facilitate adapting to bulbs of different sizes. When the clamping groove at the lower end of the converging cavity and the burner sleeve ring are attached to the upper end of the bulb, the air pump extracts the air inside the bulb through a transmission hose and the converging cavity, and at the same time, the burner sleeve ring performs hot melting sealing on the upper end of the bulb.

[0004] However, this automatic bulb sealing and exhausting device for LED bulb production still has some deficiencies in actual use. For example, although multiple workstations are set for synchronous processing operations, synchronous fixation cannot be performed, and individual repetitive operations are required for the repetitive fixation of multiple bulbs. The same is true for the blanking step, and the steps are relatively cumbersome, and the practicability is average. Content of the Utility Model

[0005] The purpose of the utility model is to provide an automatic bulb sealing and exhausting device to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: An automatic bulb sealing and exhausting device, including a machine body assembly, a sealing and exhausting assembly is fixedly installed at the top of the machine body assembly, and a feeding and clamping assembly is arranged below the sealing and exhausting assembly inside the machine body assembly;

[0007] The feeding and clamping assembly includes a placement table. At the annular edge of the top surface of the placement table, four columns are fixedly installed. At the top ends of the four columns, a placement plate is fixedly installed. At the center of the top surface of the placement table, a cylinder is fixedly installed. A plurality of circular openings are formed in the top surface of the placement plate. At the top end of the piston rod of the cylinder, a lifting plate is fixedly installed. A plurality of vertical shafts are fixedly installed on the top surface of the lifting plate. In each of the circular openings, a circular plate is fixedly embedded. At the lower middle part of the shaft body of each of the vertical shafts, a socket rotating seat is fixedly sleeved. At both ends of the socket rotating seat, a transmission rod is rotatably connected. At the other ends of the two transmission rods, a connecting rotating seat is rotatably installed. At the top ends of the two connecting rotating seats, a slider is fixedly installed. At the top ends of the two sliders, an arc-shaped clamping plate is fixedly installed. At the top end of the vertical shaft, a top head is fixedly installed. At the center of the top surface of the circular plate, a through opening corresponding to the top head is formed. On the top surface of the circular plate and on both sides of the through opening, a chute is formed. The plurality of sliders correspond to the plurality of chutes one by one, and the sliders are slidably installed in the chutes.

[0008] Preferably, the body assembly includes a body main body. On the front surface of the body main body, a control panel is provided. On both sides of the top surface of the body main body, a partition is fixedly installed.

[0009] Preferably, the sealing and exhaust assembly includes a top plate. In the middle of the top surface of the top plate, an air extraction pump is fixedly installed. On both sides of the top surface of the top plate, a telescopic rod is fixedly embedded. At the bottom ends of the two telescopic rods, a bearing frame is fixedly installed. In the middle of the bottom surface of the bearing frame, a converging plate is fixedly embedded. At the bottom end of the converging plate, a plurality of burner sleeve rings are provided.

[0010] Preferably, a transmission hose is fixedly connected to the top surface of the converging plate. The air extraction pump is communicated with the converging plate through the transmission hose.

[0011] Preferably, the plurality of circular openings are evenly distributed in a ring on the top surface of the placement plate. On the top surface of the top head, a round head groove is formed.

[0012] Preferably, the placement table is fixedly installed in the middle of the top surface of the body main body, and the placement plate is located directly below the converging plate.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: when the bottom end of the transmission rod descends, it will drive two sliders to approach each other. Thus, when the two sliders approach, they will drive two arc-shaped clamping plates to approach each other, and then multiple bulbs can be fixed synchronously. Moreover, when the arc-shaped clamping plates approach and clamp the bulbs, the top heads will also descend synchronously. Furthermore, the arc-shaped clamping plates can clamp the lamp bodies of the bulbs, and then the sealing and exhaust assembly can be used to seal and exhaust the bulbs. After the sealing and exhaust are completed, the lifting plate is driven to rise by the air cylinder. At this time, the two sliders move away from each other, so that the bulbs at all workstations can be released from fixation synchronously, and the bulbs can also be lifted synchronously by the top heads, which is convenient for the staff to remove the processed bulbs, and the practicability is stronger.

[0021] As Figures 1-5 shown, the present invention provides a technical solution: including a body assembly 1, a sealing and exhaust assembly 2 is fixedly installed at the top of the body assembly 1, and a feeding and clamping assembly 3 is arranged below the sealing and exhaust assembly 2 inside the body assembly 1;

[0022] The feeding and clamping assembly 3 includes a placing table 301. Four columns 302 are fixedly installed at the circumferential edge of the top surface of the placing table 301. A placing plate 303 is fixedly installed at the tops of the four columns 302. A cylinder 304 is fixedly installed at the center of the top surface of the placing table 301. A plurality of round openings 305 are formed in the top surface of the placing plate 303. The top end of the piston rod of the cylinder 304 is fixedly installed with a lifting plate 306. A plurality of vertical shafts 307 are fixedly installed on the top surface of the lifting plate 306. A round plate 308 is fixedly embedded in each of the round openings 305. A socket rotating seat 309 is fixedly sleeved on the lower middle part of the shaft body of each of the plurality of vertical shafts 307. A transmission rod 310 is rotatably connected to both ends of the socket rotating seat 309. The other ends of the two transmission rods 310 are rotatably installed with a connecting rotating seat 311. A slider 312 is fixedly installed at the top of the two connecting rotating seats 311. An arc-shaped clamping plate 313 is fixedly installed at the top of each of the two sliders 312. A top head 314 is fixedly installed at the top end of the vertical shaft 307. A through opening 315 corresponding to the top head 314 is formed at the center of the top surface of the round plate 308. A chute 316 is formed on both sides of the through opening 315 on the top surface of the round plate 308. The plurality of sliders 312 correspond to the plurality of chutes 316 one by one, and the sliders 312 are slidably installed in the chutes 316.

[0023] In this embodiment, the body assembly 1 includes a body main body 101. On the front surface of the body main body 101, a control panel 103 is provided. On both sides of the top surface of the body main body 101, a partition 102 is fixedly installed. The sealing and exhaust assembly 2 includes a top plate 201. In the middle of the top surface of the top plate 201, an air extraction pump 202 is fixedly installed. On both sides of the top surface of the top plate 201, a telescopic rod 203 is fixedly embedded. At the bottom ends of the two telescopic rods 203, a load-bearing frame 204 is fixedly installed. In the middle of the bottom surface of the load-bearing frame 204, a converging plate 205 is fixedly embedded. At the bottom end of the converging plate 205, a number of burner collars 206 are provided. On the top surface of the converging plate 205, a transmission hose 207 is fixedly connected. The air extraction pump 202 is connected to the converging plate 205 through the transmission hose 207. The placement table 301 is fixedly installed in the middle of the top surface of the body main body 101. The placement plate 303 is located directly below the converging plate 205. The telescopic rod 203 can effectively drive the load-bearing frame 204 to move up and down, thereby driving the converging plate 205 to move up and down, facilitating the fitting of the bottom end of the converging plate 205 and the burner collars 206 to the upper end of the bulb. The telescopic rod 203 can adjust the height of the burner collars 206 to facilitate the adaptation to bulbs of different heights. Elastic pads are adhered to the opposite surfaces of the two arc-shaped clamping plates 313. Through the elastic pads, the bulb can be protected, reducing the direct wear between the bulb and the burner collars 206. When the burner collars 206 are fitted to the upper end of the bulb, the air extraction pump 202 extracts the air inside the bulb through the transmission hose 207 and the converging plate 205. The model of the air extraction pump 202 is D15SSH-168. At the same time, the burner collars 206 perform hot melting and sealing on the upper end of the bulb.

[0024] A number of the round openings 305 are evenly distributed in a ring on the top surface of the placement plate 303. On the top surface of the top head 314, a round head groove is provided. The bulb can be placed between the two arc-shaped clamping plates 313, and the round head end of the bulb will be inserted into the round head groove provided on the top surface of the top head 314.

[0025] In use, first, the telescopic rod 203 can effectively drive the load-bearing frame 204 to move up and down, thereby driving the converging plate 205 to move up and down, facilitating the bottom end of the converging plate 205 and the burner head collar 206 to fit against the upper end of the bulb. The telescopic rod 203 can adjust the height of the burner head collar 206 to facilitate adapting to bulbs of different heights. Elastic pads are bonded to the opposite surfaces of the two arc-shaped clamping plates 313. Through the elastic pads, the bulb can be protected, reducing direct wear between the bulb and the burner head collar 206. When the burner head collar 206 fits against the upper end of the bulb, the air pump 202 extracts the air inside the bulb through the transmission hose 207 and the converging plate 205. The model of the air pump 202 is D15SSH-168. At the same time, the burner head collar 206 performs hot-melt encapsulation on the upper end of the bulb.

[0026] When loading and unloading the bulbs, the bulbs can be placed between the two arc-shaped clamping plates 313. The round head end of the bulb will be inserted into the round head groove opened on the top surface of the top head 314. Subsequently, the air cylinder 304 is started. The air cylinder 304 drives the lifting plate 306 to descend. The descent of the lifting plate 306 can drive the vertical shaft 307 to descend. The descent of the vertical shaft 307 can drive the socket rotating seat 309 to descend. Through the descent of the socket rotating seat 309, one end of the transmission rod 310 can be driven to descend. Since the other end of the transmission rod 310 is rotatably connected to a connecting rotating seat 311, the connecting rotating seat 311 is fixedly connected to the bottom surface of the slider 312, and the slider 312 is slidably installed in the chute 316. Therefore, when the bottom end of the transmission rod 310 descends, it will drive the two sliders 312 to approach each other. Furthermore, when the two sliders 312 approach each other, they will drive the two arc-shaped clamping plates 313 to approach each other, thereby synchronously fixing multiple bulbs. And while the arc-shaped clamping plates 313 approach each other and clamp the bulbs, the top head 314 will also descend synchronously. Thus, the arc-shaped clamping plates 313 can clamp the lamp body of the bulb. Subsequently, the sealing and exhaust assembly 2 can be used to seal and exhaust the bulbs. When the sealing and exhausting are completed, the air cylinder 304 drives the lifting plate 306 to rise. At this time, the two sliders 312 move away from each other, thereby synchronously releasing the fixation of the bulbs at all workstations. Moreover, the bulbs can be lifted by the top head 314 synchronously, facilitating the staff to remove the processed bulbs, with stronger practicability.

[0027] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
