Description

Technical Field

[0001] This utility model belongs to the field of spraying tooling technology, and specifically relates to a spraying tooling for television back panels. Background Technology

[0002] TV back panel spraying fixtures refer to technical measures used in the surface treatment of TV back panels to ensure spraying quality and improve production efficiency. The TV back panel is an important component of a TV assembly, responsible for protecting the internal electronic components. After the TV back panel is manufactured, it needs to be painted to improve its aesthetics and practicality. Appropriate spraying fixtures are used during TV back panel spraying to ensure efficient and high-quality spraying. TV back panel spraying fixtures generally perform spraying operations by rotating a spray gun. This presents several problems, such as the distance between the spray gun and the TV back panel, the position of the spray gun on the TV back panel area, and the height of the spray gun. These factors all determine the quality of the spraying work and may cause the paint sprayed from the spray gun to not evenly cover the surface of the TV back panel, resulting in uneven paint thickness in different areas after spraying, affecting the overall quality of the TV back panel spraying. Therefore, a new structure is proposed to solve these problems. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a TV back panel spraying fixture to solve the problems mentioned in the background technology.

[0005] The first sliding component includes a rolling groove formed on the front of the slide rail, and the second sliding component includes a guide tube for guiding the push-pull rod.

[0006] In a preferred embodiment, a fixing plate 1 for fixing the slide rail is horizontally provided at the center of the top of the main body of the spraying fixture, and a fixing plate 2 for fixing the guide tube is provided on the left and right sides of the front side of the fixing plate 1.

[0007] In a preferred embodiment, a sliding base is sleeved on the outer side of the slide rail, and a nozzle is provided on the front side of the sliding base. A moving mechanism for driving the nozzle to move up and down is provided on the front of the nozzle.

[0008] In a preferred embodiment, the slide rail has a convex shape, the inner shape of the sliding base matches the shape of the slide rail, the front of the slide rail has a horizontally opened rolling groove, and a roller is embedded in the inner wall of the front side of the inner side of the sliding base. The roller is connected to the motor built into the nozzle through a coupling.

[0009] In a preferred embodiment, the width of the roller matches the diameter of the rolling groove, the rear side of the roller is inside the rolling groove, the roller is made of rubber, and the left and right sides of the rolling groove do not penetrate the left and right sides of the slide rail. The roller is driven by a motor to move along the rolling groove, and the friction between the roller and the rolling groove drives the sliding base to move left and right along the outside of the slide rail, thereby allowing the nozzle to move flexibly left and right. The moving mechanism on the front of the nozzle includes a vertically arranged guide rail and a moving block. The moving block is fixed to the nozzle and moves up and down along the guide rail, thereby driving the nozzle to move up and down, greatly increasing the flexibility of the nozzle's movement and making the spraying more uniform.

[0010] In a preferred embodiment, an electric push rod is installed on the left and right sides of the back of the fixed plate, and a push-pull rod is connected to the output end of the front side of the electric push rod. A sliding push head is installed on the front side of the push-pull rod. The two sets of electric push rods are a synchronous mechanism, and the length of the push-pull rod is greater than the length of the guide tube.

[0011] In a preferred embodiment, a guide tube is fixed to the left and right sides of the front of the fixing plate, the front side of the left guide tube is fixed to the back side of the left fixing plate, and the right guide tube is fixed to the back side of the right fixing plate.

[0012] In a preferred embodiment, the radius of the sliding push head is greater than the radius of the push-pull rod, and the radius of the sliding push head matches the radius of the inner side of the guide tube.

[0013] The curved side of the sliding pusher is provided with four sets of interlocking strips at equal intervals, and the curved side of the guide tube is provided with four sets of sliding grooves at equal intervals and through. The length and width of the interlocking strips match the length and width of the sliding grooves, and the height of the interlocking strips is greater than the depth of the sliding grooves.

[0014] In a preferred embodiment, the left and right sets of slide rails are respectively movably sleeved on the outside of the left and right sets of guide tubes. Four sets of fitting grooves are equally spaced on the outside of the through-holes on both sides of the slide rails, and the specifications of the fitting grooves match the specifications of the fitting strips.

[0015] After adopting the above technical solution, the beneficial effects of this utility model are as follows: 1. By setting a sliding component one, the sliding component one includes a slide rail for driving the nozzle to move left and right. The slide rail is horizontally set and has a convex structure. The shape of the inner side of the sliding base matches the shape of the slide rail. A rolling groove is horizontally opened on the front of the slide rail. A roller is installed on the inner wall of the front side of the sliding base. Through the friction between the roller and the rolling groove, the sliding base is driven to move left and right along the slide rail, thereby driving the nozzle to move left and right. Therefore, the nozzle can move left and right along the outer side of the slide rail, making the movement of the nozzle more flexible, thereby making the spraying of the nozzle on the TV back panel more uniform.

[0016] 2. By setting up a second sliding component, which includes a guide tube and a push-pull rod, a sliding push head is installed on the front side of the push-pull rod. The curved side of the sliding push head is provided with four sets of fitting strips, and the four sets of fitting strips pass through four sets of sliding grooves opened on the curved side of the guide tube and are fixed to four sets of fitting grooves on the back of the slide rail. Therefore, by pushing the sliding push head back and forth with the push-pull rod, the sliding push head drives the slide rail to move back and forth along the guide tube. Then, through the synchronous work of the two sets of sliding components, the back and forth movement of the slide rail can be controlled, which in turn drives the nozzle to move back and forth. Therefore, the final effect is that through the two sets of sliding components, the back and forth movement of the nozzle can be flexibly controlled, thus greatly increasing the uniformity of spraying and improving the quality of spraying.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only one aspect of the present utility model, and not all aspects. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0026] Please see Figures 1 to 4 A TV back panel spraying fixture includes: a spraying fixture body 100 and a sliding component 200. The top of the spraying fixture body 100 is provided with a sliding component 200 for driving the nozzle to move left and right. On the left and right sides of the sliding component 200, there is a sliding component 300 for driving the nozzle to move back and forth.

[0027] Sliding assembly 1 200 includes a rolling groove 211 formed on the front of the slide rail 210, and sliding assembly 2 300 includes a guide tube 310 for guiding the push-pull rod 320.

[0028] A fixing plate 110 for fixing the slide rail 210 is horizontally provided at the center of the top of the main body 100 of the spraying fixture. A fixing plate 220 for fixing the guide tube 310 is provided on the left and right sides in front of the fixing plate 110.

[0029] A sliding base 220 is sleeved on the outside of the slide rail 210. A nozzle is provided on the front side of the sliding base 220. A moving mechanism for driving the nozzle to move up and down is provided on the front of the nozzle.

[0030] The slide rail 210 has a convex shape. The inner shape of the sliding base 220 matches the shape of the slide rail 210. The slide rail 210 has a horizontally opened rolling groove 211 on the front. A roller 221 is embedded in the inner wall of the front side of the sliding base 220. The roller 221 is connected to the motor built into the nozzle through a coupling.

[0031] The width of roller 221 matches the diameter and length of the rolling groove 211. The rear side of roller 221 is inside the rolling groove 211. Roller 221 is made of rubber. The left and right sides of the rolling groove 211 do not penetrate the left and right sides of the slide rail 210. The roller 221 is driven by a motor to move along the rolling groove 211. The friction between roller 221 and rolling groove 211 drives sliding base 220 to move left and right along the outside of slide rail 210, thereby allowing the nozzle to move flexibly left and right. The moving mechanism on the front of the nozzle includes a vertically set guide rail and a moving block. The moving block is fixed to the nozzle and moves up and down along the guide rail, thereby driving the nozzle to move up and down, greatly increasing the flexibility of the nozzle's movement, thus making the spraying more uniform.

[0032] An electric push rod is installed on the left and right sides of the back of the fixed plate 110. The output end of the electric push rod is connected to a push-pull rod 320. A sliding push head 330 is installed on the front side of the push-pull rod 320. The two sets of electric push rods are a synchronous mechanism. The length of the push-pull rod 320 is greater than the length of the guide tube 310.

[0033] A guide tube 310 is fixed on each of the left and right sides of the front of the fixing plate 110. The front side of the left guide tube 310 is fixed to the back of the left fixing plate 120, and the right guide tube 310 is fixed to the back of the right fixing plate 120.

[0034] The radius of the sliding push head 330 is greater than the radius of the push-pull rod 320, and the radius of the sliding push head 330 matches the radius of the inner side of the guide tube 310.

[0035] The curved side of the sliding pusher 330 is provided with four sets of interlocking strips 331 at equal intervals, and the curved side of the guide tube 310 is provided with four sets of sliding grooves 311 at equal intervals and through. The length and width of the interlocking strips 331 match the length and width of the sliding grooves 311, and the height of the interlocking strips 331 is greater than the depth of the sliding grooves 311.

[0036] The left and right sides of the slide rail 210 are respectively movably sleeved on the outside of the left and right sides of the guide tube 310. Four sets of fitting grooves are equally spaced on the outside of the through-hole on both sides of the slide rail 210. The specifications of the fitting grooves match the specifications of the fitting strip 331.

[0037] Example 1: Please refer to Figures 1 to 3In actual use, the top of the spraying fixture body 100 is provided with a fixing plate 110. The front side of the fixing plate 110 is provided with a horizontal slide rail 210. The front of the slide rail 210 is provided with a horizontal rolling groove 211. The outer side of the slide rail 210 is sleeved with a sliding base 220. The front side of the sliding base 220 is provided with a spray head. The slide rail 210 has a convex structure, and the inner shape of the sliding base 220 matches the shape of the slide rail 210. A roller 221 is embedded in the inner wall of the front side of the sliding base 220. The roller 221 is connected to the motor built into the spray head through a coupling. The front of the spray head is provided with a vertical moving mechanism that can drive the spray head to move up and down. The moving mechanism includes a vertically set guide rail and a moving block on the outer side of the guide rail.

[0038] In actual use, the roller 221 is driven by the motor to move along the inner side of the rolling groove 211. Since the roller 221 is made of rubber, the friction between the roller 221 and the rolling groove 211 is used to drive the sliding base 220 to move left and right along the outer side of the slide rail 210. It should be noted that the left and right sides of the rolling groove 211 are not connected to the left and right sides of the slide rail 210, thus providing a limiting effect for the sliding base 220 and preventing the roller 221 from rolling excessively and disengaging from the inside of the rolling groove 211, causing the sliding base 220 to disengage from the outer side of the slide rail 210. The friction between the roller 221 and the rolling groove 211 causes the sliding base 220 to move left and right along the slide rail 210, thereby driving the nozzle to move left and right.

[0039] A moving mechanism is provided on the front side of the nozzle. At this time, the nozzle can be moved up and down while moving left and right, which can greatly improve the flexibility of the nozzle (both the nozzle and the moving mechanism are existing technologies, and their internal structure and working principle will not be described in detail here). This can significantly improve the uniformity of the coating on the TV back panel, thus improving the coating quality.

[0040] Example 2: Please refer to Figures 1 to 4A second fixed plate 120 is located on the left and right sides of the front of a first fixed plate 110. An electric push rod is installed on the left and right sides of the back of the first fixed plate 110. A guide tube 310 is fixed on the left and right sides of the front of the first fixed plate 110. The front side of the guide tube 310 is fixed to the back of the second fixed plate 120. A push-pull rod 320 is installed at the output end of the front of the second electric push rod. A sliding push head 330 is installed on the front side of the push-pull rod 320. The push-pull rod 320 and the sliding push head 330 pass forward through the front of the first fixed plate 110 and extend into the guide tube 310. The four sets of interlocking strips 331 on the curved side of the sliding push head 330 pass through the guide tube 310. Four sets of sliding grooves 311 are opened on the curved side of the tube 310 and extend out of the outer side of the sliding grooves 311. The left and right sides of the slide rail 210 are respectively movably sleeved on the outer side of the left and right sets of guide tubes 310. Four sets of fitting grooves are equally spaced on the outer side of the passage between the slide rail 210 and the guide tube 310. Therefore, the left sliding push head 330 is fixed to the four sets of fitting grooves on the left back of the slide rail 210 through the four sets of fitting strips 331 on its outer side. The right sliding push head 330 is fixed to the four sets of fitting grooves on the right back of the slide rail 210 through the four sets of fitting strips 331 on its outer side. Thus, the two sets of sliding push heads 330 are fixed to the left and right sides of the back of the slide rail 210 respectively.

[0041] In actual operation, the left and right sets of electric push rods are synchronized mechanisms. Both sets of electric push rods (electric push rods are existing technology, and their internal structure and working principle will not be elaborated here) are activated simultaneously. The two sets of electric push rods simultaneously push forward the two sets of push-pull rods 320, causing the two sets of push-pull rods 320 to push the slide rails 210 forward through the two sets of sliding push heads 330. This causes the slide rails 210 to move forward along the two sets of guide tubes 310 respectively. Similarly, operating the electric push rods in the reverse direction causes the slide rails 210 to move backward along the two sets of guide tubes 310. Therefore, the forward and backward movement of the two sets of push-pull rods 320 drives the slide rails 210 to move forward and backward along the two sets of guide tubes 310, greatly increasing the flexibility of the nozzle's forward and backward movement. Combined with the left-right and up-down movement of the nozzle, this significantly increases the nozzle's movement flexibility during spraying, resulting in more uniform spraying of the TV back panel and thus significantly improving the spraying quality of the TV back panel.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
