Description

Technical Field

[0001] This invention relates to the technical field of television set base processing, and more particularly to a polishing device for television set base processing. Background Technology

[0002] In the television manufacturing industry, the forked stand has become the mainstream support structure due to its advantages such as high structural strength and good visual transparency. However, in order to adapt to the load-bearing requirements and appearance design styles of televisions of different sizes, the forked stands on the market exhibit a high degree of diversity in shape. Their forking angles range from 30° to 120°, and the cross-sections of the support arms cover various shapes such as circles, squares, and irregular shapes. Moreover, the surfaces often have complex curved transitions and edge structures.

[0003] Existing polishing tools generally suffer from insufficient precision in fitting these types of forked bases. Traditional polishing tools have a fixed grinding structure, making it impossible to adjust them to the specific parameters of different forked types. When facing bases with different forked angles, the fit between the tool and the surface of the forked arm varies significantly, easily leading to poor local contact. Furthermore, for forked arms with different cross-sectional shapes, existing tools struggle to automatically adjust to form a matching contact profile, resulting in uneven distribution of polishing force.

[0004] This problem of poor adaptability to different types of forks directly results in inconsistent surface finish of bases of different models after polishing. Some forked bases even have large areas that are not properly polished, which seriously affects the stability of product quality. Summary of the Invention

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments.

[0019] 3. By setting up a cleaning component and linking it with the polishing component, the ease of inserting the base can be improved and pre-damage can be avoided. When the cleaning belt is pushed outward by the base, the connecting rod drives the polishing component to rotate and change its angle, making it easier for the TV base to be smoothly inserted between the polishing component and the limiting component. This effectively avoids friction and squeezing between the base and the side wall of the polishing sponge when the base is inserted, and cleans the dust and impurities adsorbed by the base itself, reducing the pre-damage such as scratches and dents on the base surface, reducing the complexity of the polishing process, and ensuring the final polishing effect.

[0023] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0024] Example 1 Reference Figure 1 - Figure 6 This embodiment provides a polishing device for processing and producing a TV base 400, including a base 100, a bracket 101 fixedly installed on the base 100, a polishing unit 200 and a control component 300 disposed on the bracket 101, the polishing unit 200 including a drive mechanism 201, a cleaning component 202 and a polishing component 203, after the TV base 400 is fixed on the control component 300, the drive mechanism 201 drives the polishing unit 200 to slide along the surface of the TV base 400, the cleaning component 202 clamps one side of the TV base 400 and can clean dust and debris from its surface by sliding along its surface, the polishing component 203 includes a polishing part 203a and a limiting part 203b, the polishing part 203a and the limiting part 203b cooperate with each other to adaptively adjust the tilt angle with the side of the TV base 400 and slide along its surface to polish it. This enables precise adaptation to TV stand with different numbers of branches, angles, and cross-sectional shapes of arms, effectively improving the fit between the polished part 203a and the surface of the branched arms, ensuring uniform distribution of polishing force, guaranteeing consistent surface finish of various stand types after polishing, avoiding large areas of incomplete polishing, and significantly improving product quality stability.

[0025] The drive mechanism 201 is disposed on one side of the bracket 101. The drive mechanism 201 includes a lifter 201a and a sliding part 201b disposed on the lifter 201a. In this invention, a lead screw is preferably used to drive the sliding part 201b to move up and down. The lead screw can drive the sliding part 201b to slide smoothly. It should be noted that, Figure 1 and Figure 5 As shown, the connecting frame 201b-1 that is slidably sleeved on the lead screw in this invention is square and almost fits against the side bracket 101. Therefore, no additional components are added to restrict the connecting frame 201b-1 from rotating with the lead screw. In addition to supporting the control component 300, the bracket 101 can also restrict the connecting frame 201b-1.

[0026] The sliding part 201b includes a connecting frame 201b-1 slidably mounted on the lifter 201a. A first slide rail 201b-2 is provided on one side of the connecting frame 201b-1, and a cleaning component 202 is slidably mounted on one side of the first slide rail 201b-2. Figure 2 and Figure 3 As shown, the cleaning assembly 202 includes two first sliding frames 202a symmetrically arranged on one side of the sliding part 201b. Two connecting plates 202b are fixedly connected to one side of the first sliding frame 202a. Three rollers 202c are fixedly installed between the two connecting plates 202b. The same cleaning belt 202d is rotatably sleeved on the three rollers 202c. The connecting frame 201b-1 drives the cleaning assembly 202 to slide along one side surface of the TV base 400. Before polishing, the cleaning belt 202d slides along its surface to perform preliminary cleaning, removing impurities such as oil, dust, oxide layer, burrs, and residual cutting fluid. To avoid impurities causing adverse effects during the polishing process, such as scratches and pits caused by the polishing tool being rolled into the workpiece surface, or the polishing agent becoming ineffective, resulting in uneven polishing effect, or even damaging the polishing tool, ultimately affecting the polishing precision, surface quality, and adhesion of subsequent processing such as plating and coating, a scraper 202e is fixedly connected between the two connecting plates 202b, and the scraper 202e is located on the side of the cleaning belt 202d away from the TV base 400. Whether the cleaning belt 202d rolls counterclockwise along the outside of the three rollers 202c or rolls counterclockwise, the scraper 202e can clean the surface of the cleaning belt 202d.

[0027] Specifically, such as Figure 2 and Figure 5As shown, a limiting block 201b-3 is fixedly installed at the center of the first slide rail 201b-2. Two first sliding frames 202a are slidably inserted into the first slide rail 201b-2, and the two first sliding frames 202a are respectively located on both sides of the limiting block 201b-3. A first elastic element 201b-4 is fixedly installed on both sides of the limiting block 201b-3, and the first elastic element 201b-4 is fixedly connected to the first sliding frame 202a. The first elastic element 201b-4 is a tension spring. In the initial state of the TV base 400, the two cleaning strips 202d are in contact with each other. When in contact with the TV base 400, the two cleaning strips 202d are separated by the pushing force of the base, which in turn causes the two first sliding brackets 202a to slide in the opposite direction along the first slide rail 201b-2. At this time, the first elastic element 201b-4 is in a stretched state. The first elastic element 201b-4 controls the cleaning strips 202d to always be in close contact with the TV base 400 through the first sliding brackets 202a. The purpose of the limiting block 201b-3 is that if there is no limiting block 201b-3, the two first sliding brackets 202a will be offset when resetting within the first slide rail 201b-2, and the two first sliding brackets 202a cannot always be reset to the middle of the first slide. When the two first sliding brackets 202a are accurately reset to the middle of the first slide rail 201b-2, their ends can be smoothly inserted between the two cleaning strips 202d when close to the TV base 400.

[0028] A second slide rail 201b-5 is provided on one side of the connecting bracket 201b-1 and below the first slide rail 201b-2. The polishing component 203 is slidably disposed on the second slide rail 201b-5 and below the cleaning component 202. The polishing component 203a includes a second sliding bracket 203a-1 slidably disposed on one side of the sliding part 201b. A connecting seat 203a-2 is rotatably connected to the second sliding bracket 203a-1. A first driving component 203a-3 is rotatably mounted on the connecting seat 203a-2. A polishing sponge 203a-4 is fixedly connected to the output shaft of the first driving component 203a-3. By rotating the first driving component 203a-3 relative to the connecting seat 203a-2, the polishing sponge 203a-4 can adaptively adjust its tilt angle to fit the surface of the TV base 400. The first driving component 203a-3 controls the polishing sponge 203a-4 to polish the surface of the base through the output shaft.

[0029] The limiting member 203b includes a third sliding frame 203b-1 slidably disposed on one side of the sliding part 201b. A support frame 203b-2 is fixedly mounted on the third sliding frame 203b-1. A limiting roller 203b-3 is rotatably mounted on the support frame 203b-2. Both the second sliding frame 203a-1 and the third sliding frame 203b-1 are slidably inserted into the second slide rail 201b-5. Both the second sliding frame 203a-1 and the third sliding frame 203b-1 are provided with a second elastic member 201b-6, and the second elastic member 201b-6 is fixedly connected to the inner wall of the second slide rail 201b-5. The second elastic element 201b-6 is a compression spring. The limiting roller 203b-3 rolls along the surface of the TV base 400. The second elastic element 201b-6 pushes the second sliding frame 203a-1 and the third sliding frame 203b-1 to make the limiting roller 203b-3 and the polishing sponge 203a-4 fit tightly against the surface of the TV base 400. When the polishing sponge 203a-4 polishes the TV base 400, the limiting roller 203b-3 supports the TV base 400, so that the TV base 400 and the polishing sponge 203a-4 always remain in close contact.

[0030] like Figure 1 and Figure 6 As shown, the bracket 101 is equipped with a control assembly 300 for fixing the TV base 400 and controlling the rotation of the TV base 400. The control assembly 300 includes a second drive member 301 fixedly installed on the protruding end of the bracket 101. A support plate 302 is fixedly connected to the output shaft of the second drive member 301. The second drive member 301 can control the rotation of the support plate 302 through its output shaft. A fixing frame 303 is fixedly connected to the end of the support plate 302 away from the output shaft of the second drive member 301. A third drive member 304 is provided on the fixing frame 303. A clip 305 is fixedly connected to the output end of the actuator 304. The third drive unit 304 can control the rotation of the clip 305 through its output shaft. A rubber pad 306 is fixedly installed at the bottom of the support plate 302 and directly below the output shaft of the second drive unit 301. When the polishing unit 200 is clamped on the side of the TV base 400 and moves along its upward surface to perform polishing operations, it will generate a certain upward thrust on the TV base 400. The rubber pad 306 plays a certain role in limiting and protecting the TV base 400 and can prevent the clip 305 from deforming.

[0031] After connecting the TV base 400 to the clip 305, the polishing operation begins. After the polishing unit 200 completes one up-and-down reciprocating operation, the second drive unit 301 drives the TV base 400 to rotate 20°-45° through the support plate 302. The specific rotation angle is set according to the thickness / size of the side end of the TV base 400 of the specific model. When the second drive unit 301 drives the side end of the TV base 400 to rotate 180°, the polishing unit 200 completes the polishing operation on one side end surface of the TV base 400. At this time, the second drive unit 301 needs to drive the side end of the TV base 400 to rotate 180° in the opposite direction before the third drive unit 304 is activated to control the rotation of the TV base 400 through the clip 305, thereby switching the side end of the TV base 400 that needs to be polished.

[0032] Example 2 The difference between this embodiment and Embodiment 1 is that, in the initial state, the polishing surface of the polishing sponge 203a-4 is always perpendicular to the ground. This setting easily leads to friction and compression between the base and the side wall of the polishing sponge 203a-4 when the TV base 400 is inserted between the polishing component 203a and the limiting component 203b. This causes inconvenience in inserting the TV base 400 and easily creates additional scratches, dents, or coating damage on the surface of the TV base 400. This necessitates additional treatment of these pre-damages during the polishing process, increasing the complexity and time consumption of the polishing procedure. After polishing, the base surface may still have traces that are difficult to repair, failing to achieve the expected smoothness and precision requirements, directly affecting the product's appearance quality and performance. This embodiment provides a solution to achieve rotation of the polishing component 203a through the linkage of the cleaning component 202 and the polishing component 203, thereby solving the above problems.

[0033] Specifically, a first connecting rod 203a-10 is rotatably mounted on a connecting plate 202b above the polished part 203a. A groove 203a-11 is formed on the first connecting rod 203a-10. A slider 203a-12 is fixedly connected to the outside of the connecting seat 203a-2, and the slider 203a-12 is slidably inserted into the groove 203a-11. A second connecting rod 203b-4 is rotatably mounted on a third sliding frame 203b-1, and the second connecting rod 203b-4 is rotatably connected to a first sliding frame 202a located directly above it. The two sets of cleaning belts 202d slide along the surface of the television base 400 and are... As the TV base 400 moves outward in the opposite direction, the third sliding bracket 203b-1 pulls the limiting member 203b horizontally via the second connecting rod 203b-4. The first connecting rod 203a-10 on the connecting plate 202b pulls the connecting seat 203a-2 relative to the second sliding bracket 203a-1 via the slider 203a-12, causing it to rotate. The connecting seat 203a-2 drives the first driving member 203a-3 to rotate towards the cleaning component 202, changing the angle of the polishing surface of the polishing sponge 203a-4, thus facilitating the insertion of the TV base 400 between the polishing member 203a and the limiting member 203b.

[0034] To allow the polishing sponge 203a-4 for adjusting the angle of the connector 203a-2 to fit more closely to the TV base 400, a support rod 203a-5 is fixedly connected to the inner side of the connector 203a-2 and below the first driving member 203a-3. An elastic telescopic rod 203a-6 is rotatably sleeved on the outer wall of the support rod 203a-5. The elastic telescopic rod 203a-6 consists of a telescopic rod and a built-in compression spring. A first limiting rod 203a-7 is fixedly connected to the telescopic end of the telescopic rod. Two sliding grooves 203a-8 are symmetrically opened on the inner side of the connector 203a-2. The two ends of the first limiting rod 203a-7 are slidably inserted into the two sliding grooves 203a-8 respectively. The support rod 203a-5 and the first limiting rod 203a-7 together support the bottom of the first driving member 203a-3.

[0035] Specifically, such as Figure 7As shown, after the connecting seat 203a-2 is rotated by the pull rod, when the polishing sponge 203a-4 needs to be in contact with the surface of the TV base 400 and at a slight vertical angle to the ground, the first driving member 203a-3 rotates along the axis that is rotatably connected to the connecting seat 203a-2. The first driving member 203a-3 pushes the elastic telescopic rod 203a-6 to retract by pressing the first limiting rod 203a-7. At this time, the first limiting rod 203a-7 can both support the first driving member 203a-3 and not affect the rotation of the first driving member 203a-3. After the polishing operation is completed, when the polishing unit 200 is moved away from the TV base 400, the cleaning component 202 begins to reset. At this time, the first connecting rod 203a-10 will drive the connecting seat 203a-2 to rotate in the opposite direction until the connecting seat 203a-2 returns to a state parallel to the ground. At the same time, due to the loss of the pushing force from the TV base 400, the polishing sponge 203a-4 will be pushed by the elastically released elastic telescopic rod 203a-6 to slide the first limiting rod 203a-7 along the sliding groove 203a-8 to reset, so that the connecting seat 203a-2 and the first driving member 203a-3 are both parallel to the ground.

[0036] Furthermore, a second limiting rod 203a-9 is fixedly connected to the inner side of the connecting seat 203a-2 and above the first driving member 203a-3. By setting the second limiting rod 203a-9, it is beneficial to avoid the problem of failure to reset caused by excessive rotation of the connecting seat 203a-2 or the first driving member 203a-3.

[0037] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
