Description

Technical Field

[0001] This utility model relates to the field of projector manufacturing technology, and in particular to a projector housing assembly equipment. Background Technology

[0002] Projector housings typically consist of a base plate, two side plates, a top plate, and two front panels. In existing technology, to facilitate component installation, the two side plates are usually installed onto the base plate first, followed by the electronic components. Then, the front panel, which integrates the electronic components, is installed onto the base plate, and finally, the top plate is installed. However, for industrial projectors operating in harsh environments, screws are needed to connect the components during housing assembly to ensure structural stability. Currently, housing assembly is usually done manually. This involves manually aligning the two side plates with the base plate, inserting them into grooves in the base plate, and then connecting the base plate and side plates with screws. When tightening the screws, the screws are usually turned from the outside of the base plate inwards, requiring the base plate to be flipped over to expose its bottom surface. This makes the side plates prone to falling off during installation, requiring manual repositioning, which is inconvenient and hinders rapid assembly. Utility Model Content

[0003] In view of the shortcomings of the above-mentioned prior art, this application provides a projector housing assembly device that can automatically connect the bottom plate and side plates of the housing, improve assembly efficiency, and has strong practicality.

[0004] To achieve the above objectives, the present invention employs the following technology:

[0005] A projector housing assembly device includes: a support plate, a load-bearing component, and a screw-tightening component.

[0006] There are two parallel support plates, with multiple conveyor wheels arranged between them along their length. The bearing assembly includes a bearing plate located between two of the conveyor wheels for supporting the bottom plate of the outer casing. Both sides of the bearing plate have through grooves, and clamping plates that move along the width direction are provided in the through grooves to limit the movement of the bottom plate on both sides. A pressure plate that moves vertically is provided inside the clamping plates to limit the movement of the side plates of the outer casing. The screw-tightening assembly includes a support frame located inside the clamping plate and moving along its thickness direction. Multiple movable limiting tubes are arranged sequentially along the length direction on the support frame. The upper end of the limiting tube is located in the through groove to accommodate the screw, and a drill bit that moves vertically and rotates around its own axis is provided inside the limiting tube to turn the screw.

[0007] Furthermore, a support rod is provided at the top of the clamping plate, and the pressure plate is sleeved on the support rod and connected to the moving end of the first vertical lifting mechanism. The first vertical lifting mechanism is installed on the top plate, and the top plate is installed on the support rod.

[0008] Furthermore, a baffle that moves vertically through one end of the support plate is used to abut against the bottom plate of the outer casing.

[0009] Furthermore, a push plate is provided above the support plate. The push plate is connected to the moving end of the horizontal linear mechanism. The horizontal linear mechanism is arranged along the length of the support plate and installed on the lifting plate. The lifting plate is connected to the moving end of the second vertical lifting mechanism, which is installed on the support plate.

[0010] Furthermore, a side frame is provided on the inner side of the clamping plate. The side frame is connected to the moving end of the bidirectional linear mechanism, and both ends are provided with a first screw arranged along its width direction. Both ends of the support frame are sleeved on the first screw and locked with nuts. The bidirectional linear mechanism is installed at the bottom of the bearing plate.

[0011] Furthermore, the support frame is provided with a guide rod and a second screw arranged along its length. A connecting plate is provided on the outside of the limiting tube. The connecting plate is sleeved on the guide rod and the second screw and locked with a nut. A positioning tube is also provided on the side of the connecting plate, and the drill bit passes through the positioning tube.

[0012] Furthermore, a through rod is provided at the bottom of the connecting plate, which passes through the movable plate. The lower end of the drill bit is rotatably installed in the movable plate and connected to the output end of the power equipment. The power equipment is installed on the movable plate. One end of the movable plate is sleeved on the slide rod. Both ends of the slide rod are slidably connected to the horizontal plate. The horizontal plate is connected to the movable end of the third vertical lifting mechanism. The third vertical lifting mechanism is installed at the bottom of the bearing plate.

[0013] The advantages of this utility model are as follows: when assembling the bottom plate and side plate of the outer shell, the bottom plate is limited by the clamping plate and the side plate is limited by the pressure plate. The screws are automatically connected to the bottom plate and the side plate by the screw tightening assembly, thereby realizing the connection between the bottom plate and the side plate. This not only improves the assembly efficiency, but also improves the degree of production automation. Furthermore, the clamping plate, pressure plate and drill bit can all move to adapt to outer shells of different sizes. Attached Figure Description

[0020] To make the objectives, technical solutions and advantages of the present utility model clearer, the implementation methods of the present utility model will be described in detail below with reference to the accompanying drawings. However, the embodiments described in the present utility model are only some embodiments of the present utility model, and not all embodiments.

[0021] like Figures 1-5 As shown, this example provides a projector housing assembly device, including: a support plate 100, a load-bearing component 200, and a screw-tightening component 300.

[0022] There are two support plates 100, which are parallel to each other. Multiple conveyor wheels 101 are arranged between the support plates 100 along their length direction to convey the bottom plate of the outer casing. The bearing assembly 200 includes a bearing plate 201 disposed between two of the conveyor wheels 101 for supporting the bottom plate of the outer casing. Each bearing plate 201 has a through groove 202 on both sides. A clamping plate 203, movable along the width direction, is provided in each through groove 202 to limit the movement of the bottom plate on both sides. A pressure plate 20, movable along the vertical direction, is provided inside the clamping plate 203. 4. Used to limit the side panel of the outer shell to prevent the side panel of the outer shell from being pushed off during the screw tightening process; the screw tightening assembly 300 includes a support frame 301 disposed inside the clamping plate 203 and movable along its thickness direction. Multiple movable limiting tubes 302 are sequentially disposed on the support frame 301 along its length direction. The upper end of the limiting tube 302 is located in the through groove 202 for accommodating the screw. The limiting tube 302 is provided with a drill bit 303 that moves vertically and rotates around its own axis for turning the screw to connect the bottom plate and the side plate of the outer shell.

[0023] Specifically, the top of the clamping plate 203 is provided with a support rod 205, and the pressure plate 204 is sleeved on the support rod 205 and connected to the moving end of the first vertical lifting mechanism. The first vertical lifting mechanism is installed on the top plate 206, and the top plate 206 is installed on the support rod 205. After the bottom plate of the outer shell is located on the bearing plate 201, the two outer shell side plates are placed on both sides of the bottom plate of the outer shell, and the lower end of the outer shell side plates is fitted into the groove of the bottom plate of the outer shell. Then, the pressure plate 204 is driven to move downward by the first vertical lifting mechanism to apply a downward force to the side plates, thereby clamping the side plates.

[0024] Specifically, a baffle 207 is provided at one end of the support plate 201 and is arranged to move vertically. When the bottom plate of the outer shell is transported to the support plate 201, the baffle 207 is used to abut against the bottom plate of the outer shell and limit one end of it. After the assembly is completed, the baffle 207 can be moved downward.

[0025] Specifically, a push plate 208 is provided above the support plate 201. The push plate 208 is connected to the moving end of the horizontal linear mechanism. The horizontal linear mechanism is arranged along the length of the support plate 100 and is installed on the lifting plate 209. The lifting plate 209 is connected to the moving end of the second vertical lifting mechanism, which is installed on the support plate 100. When it is necessary to transfer the bottom plate of the outer shell to the support plate 201, the lifting plate 209 is driven to move downward by the second vertical lifting mechanism. Then, the push plate 208 is driven to move towards the support plate 201 by the horizontal linear mechanism, thereby pushing the bottom plate of the outer shell onto the support plate 201. After the bottom plate of the outer shell and the side plate are assembled, they are pushed off the support plate 201 again by the push plate 208 and moved onto the conveyor wheel 101. Then the push plate 208 is raised to wait for the next pushing action.

[0026] Specifically, a side frame 210 is provided on the inner side of the clamping plate 203. The side frame 210 is connected to the moving end of the bidirectional linear mechanism. The bidirectional linear mechanism is installed at the bottom of the bearing plate 201. The two clamping plates 203 can be driven to move towards each other simultaneously through the bidirectional linear mechanism, thereby clamping the bottom plate of the outer shell for easy assembly. Both ends of the side frame 210 are provided with first screws 211 arranged along its width direction. Both ends of the support frame 301 are sleeved on the first screws 211 and locked with nuts. Loosening the nuts allows the support frame 301 to be moved, thereby adjusting the position of the drill bit 303 and the limiting tube 302. Then, the support frame 301 is locked with nuts to accommodate the bottom plate of the outer shell with different screw installation positions.

[0027] Specifically, the support frame 301 is provided with a guide rod 304 and a second screw 305 arranged along its length. A connecting plate 306 is provided on the outside of the limiting tube 302. The connecting plate 306 is sleeved on the guide rod 304 and the second screw 305 and locked with a nut. By loosening the nut and moving the connecting plate 306, the position of the limiting tube 302 and the drill bit 303 can be further adjusted. Then, the connecting plate 306 is locked with a nut, so as to adapt to the bottom plate and side plate of different sizes of the outer shell.

[0028] More specifically, a positioning tube 307 is provided on the side of the connecting plate 306, and the drill bit 303 passes through the positioning tube 307, thereby providing a limiting effect during the rotation of the drill bit 303, making its rotation process more stable.

[0029] Specifically, the bottom of the connecting plate 306 is provided with a through rod 308, which passes through the movable plate 309. When the connecting plate 306 moves, it can drive the movable plate 309 to move synchronously without affecting the up-and-down movement of the movable plate 309. The lower end of the drill bit 303 is rotatably mounted in the movable plate 309 and connected to the output end of the power equipment. The power equipment is mounted on the movable plate 309. One end of the movable plate 309 is sleeved on the slide rod 310. Both ends of the slide rod 310 are slidably connected to the horizontal plate 311. The horizontal plate 311 is connected to the movable end of the third vertical lifting mechanism. The third vertical lifting mechanism is mounted on the bearing plate 20. At the bottom, when the connecting plate 306 moves along the width direction of the support frame 301, it drives the moving plate 309 to move synchronously. The moving plate 309 and the horizontal plate 311 move relative to each other to avoid interference between the components. When connecting the bottom plate and the side plate of the outer shell, the screw is put into the limiting tube 302. The upper end of the drill bit 303 is located in the limiting tube 302, which prevents the screw from falling further. Then, the horizontal plate 311 is driven to move upward by the third vertical lifting mechanism, which drives the moving plate 309 to move upward. At the same time, the power equipment drives the drill bit 303 to rotate, thereby connecting the screw to the bottom plate and the side plate of the outer shell.

[0030] Since the above are merely preferred embodiments of this utility model and are not intended to limit this utility model, it is obvious that those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
