Description

Technical Field

[0001] The present application relates to the field of auxiliary clamping devices, and in particular to an auxiliary clamping device for glue injection of advertising light signs. Background Art

[0002] Advertising light billboards can display a variety of text patterns through LED light boards, and are an important tool for displaying information in places such as shopping malls and stores.

[0003] In related technologies, such as Figure 1 The advertising light board 1 is composed of a base plate 12 and a light board 11, wherein the light board 11 is fixed to the base plate 12 by glue. During the manufacturing process of this type of advertising light board 1, when gluing the base plate 12 and the light board 11, it is necessary to first use several adhesive tapes to temporarily glue the light board 11 to the base plate 12, and then manually use a glue gun 6 to inject glue at the connection between the light board 11 and the base plate 12.

[0004] Regarding the aforementioned related technologies, the method of temporarily fixing the light board to the base plate with tape is not only inconvenient to operate, but also requires removing the tape after the glue is injected at the connection between the light board and the base plate, making the overall operation cumbersome and time-consuming. In addition, the tape between the base plate and the light board easily interferes with the movement path of the glue gun during glue injection, which can easily affect the consistency of the glue gun when injecting glue at the connection between the light board and the base plate. Therefore, there is room for improvement. Utility Model Content

[0005] In order to facilitate temporary positioning and fixing of the light board on the base plate when injecting glue at the connection between the light board and the base plate of the advertising light board, the present application provides an auxiliary clamping device for injecting glue on the advertising light board.

[0006] This application provides an auxiliary clamping device for glue injection of advertising light signs, which adopts the following technical solutions:

[0007] An auxiliary clamping device for glue injection of advertising light boards includes a workbench, on which two clamping limit plates are vertically supported. The two clamping limit plates are arranged opposite to each other. A clamping drive component is also provided on the workbench, which is driven and connected to the two clamping limit plates. The clamping drive component is used to drive the two clamping limit plates to move relative to each other.

[0008] By adopting the above technical solution, after the light board and the base plate to be connected and fixed are placed between the two clamping limit plates, the two clamping limit plates are driven closer to each other by the clamping drive member until the light board is pressed tightly against the base plate, so that the light board can be temporarily limited and fixed on the corresponding base plate, which is convenient for subsequent manual injection of glue into the connection between the light board and the base plate through a glue gun to fix the light board to the base plate. Compared with the traditional method of temporarily fixing the light board to the base plate with several tapes, the operation is simpler, and there is no need to tear off the tape at the connection between the light board and the base plate after the glue injection is completed, thereby improving the overall manufacturing efficiency of the advertising light board.

[0009] Preferably, the clamping drive component includes a clamping cylinder arranged on opposite sides of the workbench, and the two clamping limit plates are located between the clamping cylinders on both sides of the workbench; the piston rods of the clamping cylinders on both sides of the workbench are respectively connected to the two clamping limit plates.

[0010] By adopting the above technical solution, the clamping cylinders on both sides of the workbench drive the respective piston rods to extend and retract, thereby driving the two clamping limit plates to move relatively away from or closer to each other, so as to achieve the clamping and release of the lamp board and the substrate through the two clamping limit plates.

[0011] Preferably, sliders are provided at the bottom of both ends of the clamping limit plate, and the workbench supports two slide rails corresponding to the sliders at both ends of the clamping limit plate, and the sliders at both ends of the clamping limit plate are respectively slidably connected to the corresponding slide rails.

[0012] By adopting the above technical solution, through the cooperation of the slider and the slide rail, on the one hand, it is helpful to reduce the friction between the clamping limit plate and the workbench, making it easier for the clamping limit plate to slide more smoothly on the workbench. On the other hand, it realizes auxiliary support for the clamping limit plate, which is helpful to improve the stress condition at the connection between the piston rod of the clamping cylinder and the clamping limit plate.

[0013] Preferably, flexible protective pads are connected to opposite sides of the two clamping limit plates.

[0014] By adopting the above technical solution, on the one hand, it is helpful to reduce the impact of the clamping limit plates on the light board and the substrate when the light board and the substrate are clamped by the two clamping limit plates, so that the light board and the substrate are not easily damaged. On the other hand, the friction between the two clamping limit plates and the light board and the substrate can be increased through the flexible protective pad, which is conducive to clamping the light board and the substrate more firmly through the two clamping plates.

[0015] Preferably, a storage rack is vertically supported on the workbench, and a storage ring is connected to the top of the storage rack, and the storage ring is used for the glue gun to pass through.

[0016] By adopting the above technical solution, after manually injecting glue between the base plate and the light board with a glue gun, the glue gun can be inserted into the storage ring and the glue gun handle can be overlapped on the storage ring to realize the storage of the glue gun, which is convenient for taking and placing the glue gun when using it.

[0017] Preferably, a glue collection box is further provided at the bottom of the storage rack, and the glue collection box is located at the bottom of the storage ring and is arranged opposite to the storage ring.

[0018] By adopting the above technical solution and setting up a glue collection box, the glue dripping from the glue outlet of the glue gun stored on the storage ring can fall into the glue collection box. The glue collection box can be used to collect the residual glue in a centralized manner, thereby reducing the situation where glue dripping from the glue gun contaminates the workbench surface.

[0019] Preferably, a support plate is further provided at the bottom of the storage rack, the support plate is provided with a limiting groove, and the glue collection box is embedded in the limiting groove.

[0020] By adopting the above technical solution, the limit groove on the support plate is used to limit the glue collection box, thereby reducing the situation in which people accidentally touch the glue collection box and cause it to move away from the glue gun during subsequent production and processing.

[0021] Preferably, a storage drawer is further provided at the bottom of the workbench, and the storage drawer is slidably installed at the bottom of the workbench.

[0022] By adopting the above technical solution, daily spare production tools such as glue guns and scrapers can be stored in the storage drawer at the bottom of the workbench, which is conducive to keeping the workbench clean and tidy when in use.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. Place the light board and base plate to be bonded between the two clamping limit plates on the workbench. Use the clamping drive to drive the two clamping limit plates closer to each other to clamp the light board and the base plate until the light board is pressed tightly against the base plate. This will achieve temporary limit fixation of the light board, making it easier for manual glue guns to be used to inject glue at the joint between the light board and the base plate to connect the base plate and the light board.

[0025] 2. Flexible protective pads are provided on opposite sides of the two limit plates; when the light board and the base plate are subsequently clamped by the two clamping limit plates, it is beneficial to reduce the wear of the clamping limit plates on the light board and the base plate, and at the same time it is beneficial to increase the friction between the clamping limit plates and the light board and the base plate, thereby facilitating the two clamping limit plates to clamp the light board and the base plate more firmly.

[0026] 3. The sliders at both ends of the clamping limit plate are slidably connected to the corresponding slide rails of the workbench. On the one hand, it is beneficial to reduce the friction between the clamping limit plate and the workbench, so that the clamping limit plate can slide smoothly on the workbench. On the other hand, the auxiliary support of the clamping limit plate can be achieved by cooperating with the sliders at both ends of the clamping limit plate and the corresponding slide rails, which is beneficial to improve the force condition at the connection between the clamping cylinder piston rod and the clamping limit plate.

[0033] The following is combined with Figure 2-4 This application is described in further detail.

[0034] The present application discloses an auxiliary clamping device for glue injection of advertising light signs, referring to Figure 2 , including a workbench 2, on which two clamping limit plates 3 are supported and arranged opposite to each other, and the workbench 2 is also provided with a clamping driving member for driving the two clamping limit plates 3 to move relative to each other.

[0035] The clamping drive component includes a clamping cylinder 4 arranged on opposite sides of the workbench 2. The number of the clamping cylinders 4 on the side of the workbench 2 is specifically two. The clamping cylinders 4 are fixed to the workbench 2 by a bracket 41 to achieve the installation and fixation of the clamping cylinders 4. The clamping cylinders 4 on opposite sides of the workbench 2 are arranged relative to each other. The two clamping limit plates 3 are located between the clamping cylinders 4 on both sides of the workbench 2. The piston rods of the clamping cylinders 4 on the side of the workbench 2 are connected to the opposite clamping limit plates 3. Subsequently, the clamping cylinders 4 on both sides of the workbench 2 drive their own piston rods to extend and retract, thereby driving the two clamping limit plates 3 away from or close to each other, so as to facilitate the clamping or release of the lamp board 11 and the base plate 12 through the two clamping limit plates 3. In other embodiments, the clamping cylinders 4 can also be replaced by oil cylinders.

[0036] Flexible protective pads 30 are provided on opposite sides of the two clamping limit plates 3. In this embodiment, the flexible protective pads 30 are rubber pads; the flexible protective pads 30 are bonded to the clamping limit plates 3 using glue. The provision of the flexible protective pads 30 allows the flexible protective pads 30 to reduce the impact of the two clamping limit plates 3 on the light board 11 and the base plate 12 when the clamping drive member subsequently drives the two clamping limit plates 3 toward each other to clamp the light board 11 and the base plate 12, thereby reducing damage to the light board 11 and the base plate 12. Furthermore, the flexible protective pads 30 on the two clamping limit plates 3 increase the friction between the two clamping limit plates 3 and the base plate 12, thereby limiting displacement of the light board 11 or the base plate 12 when glue is subsequently injected into the connection between the light board 11 and the base plate 12 using the glue gun 6.

[0037] The clamping limit plate 3 is provided with a connecting plate at the bottom of each end, and a slider 31 is installed at the bottom of the connecting plate; the slider 31 is connected to the connecting plate by bolts. The workbench 2 is installed with two slide rails 32 corresponding to the sliders 31 at both ends of the clamping limit plate 3. The slide rails 32 are connected to the workbench 2 via countersunk screws. The length of the two slide rails 32 is arranged parallel to the length of the clamping cylinder 4. The sliders 31 at the bottom of each end of the clamping limit plate 3 are respectively slidably connected to the corresponding slide rails 32. This arrangement, on the one hand, helps reduce the friction between the clamping limit plate 3 and the workbench 2 surface, facilitating the clamping limit plate 3 to slide smoothly on the workbench 2 surface. On the other hand, the cooperation between the slider 31 and the slide rail 32 can help support the clamping limit plate 3, thereby improving the stress conditions at the connection between the piston rod of the clamping cylinder 4 and the clamping limit plate 3, making the connection between the piston rod of the clamping cylinder 4 and the clamping limit plate 3 less susceptible to damage.

[0038] Reference Figure 2 and Figure 3A storage rack 5 is also vertically mounted on the workbench 2. A support plate 50 is vertically connected to the bottom of the rack 5. The support plate 50 is welded to the workbench 2, securing the rack 5 securely to the workbench 2. A storage ring 51 is horizontally welded to the top of the rack 5. This ring is used to hold the glue gun 6. After the glue injection operation at the connection between the light panel 11 and the base plate 12 is completed, the glue gun 6 can be inserted into the ring 51 and the handle of the glue gun 6 can be placed on the ring to store the glue gun 6.

[0039] A glue collection box 52 is also provided on the support plate 50. The glue collection box 52 is located directly below the storage ring 51. The glue dripping from the glue outlet of the bottom end of the glue gun 6 on the storage ring 51 can fall into the glue collection box 52, thereby reducing the contamination of the workbench 2 by the glue dripping from the glue outlet of the glue gun 6.

[0040] The support plate 50 is provided with a limiting groove 501 corresponding to the glue collecting box 52, and the bottom of the glue collecting box 52 is embedded in the limiting groove 501 on the support plate 50. The limiting groove 501 is used to limit the glue collecting box 52 so that the glue collecting box 52 is not easy to separate from the support plate 50.

[0041] Reference Figure 2 and Figure 4 The workbench 2 is also provided with a storage drawer 21 at the bottom. Two vertical boards 22 are vertically connected to the bottom surface of the workbench 2. The two vertical boards 22 are arranged opposite each other. A horizontal board 23 is vertically connected to the bottom of the opposite side of the two vertical boards 22. The storage drawer 21 is located between the two vertical boards 22, and the bottom of the storage drawer 21 overlaps the two horizontal boards 23, so that the storage drawer 21 can be slidably installed at the bottom of the workbench 2. Various tools required for daily processing of the advertising light board 1, such as spare glue guns 6 and scrapers, can be placed in the storage drawer 21, which is conducive to keeping the workbench 2 clean. A handle is connected to one end of the storage drawer 21, which makes it easy to pull the storage drawer 21 out of the bottom of the workbench 2 or push it back.

[0042] The implementation principle of the embodiment of the present application is that after the lamp board 11 and the substrate 12 to be connected are placed between the two clamping limit plates 3 at the workbench 2 and the positions of the lamp board 11 and the substrate 12 are adjusted, the clamping cylinders 4 at the two ends of the workbench 2 are cooperated to drive the two clamping limit plates 3 closer to each other until the lamp board 11 is pressed tightly against the substrate 12, so that the lamp board 11 can be temporarily fixed on the substrate 12, so that glue can be manually injected at the connection between the substrate 12 and the light board 11 through the glue gun 6 later.

[0043] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
