Description

Technical Field

[0001] This invention relates to the field of product processing technology, and more specifically, to a continuous polishing apparatus for processing 3C products. Background Technology

[0002] The term "3C products" is a collective term for computer, communication, and consumer electronics products, also known as "information appliances." Examples include computers, tablets, mobile phones, and digital audio players. Because 3C products are generally small, they are often referred to as "small 3C appliances." The rapid development and adoption of 3C products in homes is based on the rapid advancements in integrated circuits and the internet. Currently, the processing of 3C products requires polishing and grinding the panel materials.

[0003] A search revealed that patent publication number CN208557089U discloses a polishing device for processing copper-plated silver products. The device includes an operating table, with a motor housing and a polishing box on the upper part and a support column at the bottom. The motor housing houses a motor, and a control panel is located on the front side of the motor housing, including a motor switch and a motor speed control panel. The motor is connected to a polishing wheel located inside the polishing box via a polishing shaft. The polishing box has an opening at the bottom, and a dust collection chamber is located directly below the bottom of the polishing box. The front side of the polishing box has a glass observation window, and the rear has a door. A fastening nut is installed on one side, and an adjusting screw passes through the fastening nut and the side wall of the polishing box. One end of the adjusting screw is fixedly connected to a workpiece fixing plate inside the polishing box, and the other end is connected to a handle outside the polishing box. The workpiece fixing plate is located directly below the polishing wheel.

[0004] Although this patent can handle the noise and dust generated during product polishing, the equipment still has the following drawbacks in actual use: 1. Generally, the equipment can only fix one set of product panels. Therefore, after a set of product panels is polished, the worker needs to remove the polished products from the equipment and fix the unpolished products to continue polishing, which wastes a lot of polishing time. 2. Moreover, workers often polish the product surface by rubbing the sanding belt against it. The sanding belt machine will drive the sanding belt to rotate in one direction, so the product surface is prone to having scratches in one direction when polished. Summary of the Invention

[0005] The purpose of this invention is to address the problem that existing continuous polishing devices for 3C product processing cannot continuously polish multiple products and are prone to producing polishing marks in one direction.

[0012] As a preferred technical solution of this application, a fixing ring is installed on the inner wall of the fixing cylinder, the sliding rod is slidably connected to the fixing ring, and a first spring is connected in series on the rod wall of the sliding rod located between the fixing plate and the fixing ring.

[0013] As a preferred technical solution of this application, the limiting component includes pressure blocks symmetrically arranged on the upper and lower surfaces of the fixing plate and a second spring connected between the pressure blocks and the back of the fixing plate, and the end of the pressure block away from the second spring is an inclined triangular structure.

[0014] As a preferred technical solution of this application, the support frame is further provided with a clamping assembly. The clamping assembly includes a screw threaded to the side wall of the support frame, a push block slidably connected to the inner wall of the support frame, a pressure rod slidably connected to the top of the support frame, and a pressure plate installed on the top of the pressure rod. The end of the screw located inside the support frame is rotatably connected to the side wall of the push block, the bottom of the pressure rod is slidably connected to the surface of the push block, and the surface of the fixing plate is also provided with a groove that is slidably connected to the pressure plate.

[0015] As a preferred technical solution of this application, the driving mechanism includes a motor installed on the top wall of the box body, a half gear connected to the output end of the motor, a crank rod rotatably connected to the top wall of the box body, a full gear fixedly sleeved on the inner wall of the crank rod located inside the box body, and a third spring connected in series on the rod wall between the top wall of the crank rod located inside the box body and the upper surface of the full gear.

[0016] As a preferred technical solution of this application, the rotating assembly includes multiple sets of connecting rods equidistantly mounted on the outer wall of the box, a gear ring connected to the bottom of the multiple sets of connecting rods, and a gear disc disposed at the bottom end of the crank rod, wherein the gear disc and the gear ring mesh with each other, and the top of the support column is connected to the rod wall of a set of connecting rods.

[0020] In the scheme of this application:

[0021] 1. First, fix the panels of the two sets of 3C products to be processed on the upper and lower sides of the fixing plate using the limiting components. Then, polish the previous product panel with the polishing plate. After the upper product panel is polished, the fixing plate can be flipped by the movable handle to flip the other unpolished product panel to the upper side for further polishing. Then, remove the processed product panel that has been flipped to the lower side and fix the other unpolished product panels on top again. Repeat this process to continuously polish multiple sets of panels by flipping the fixing plate. This eliminates the need to remove the polished panels and fix other panels after polishing, saving a lot of polishing time.

[0022] 2. After the 3C product panel is fixed on the fixing plate, the drive mechanism works in conjunction with the rotating component to drive the polishing plate to rotate back and forth slightly on the panel surface, which is convenient for polishing the panel surface in different directions and avoids the appearance of scratches in more than one direction on the panel surface caused by polishing in only one direction.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0035] Therefore, the following detailed description of embodiments of the present invention is not intended to limit the scope of the claimed invention, but merely illustrates some embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0036] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0037] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0038] In the description of this invention, it should be noted that the terms "upper," "lower," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this invention is in use, or the orientation or positional relationship commonly understood by those skilled in the art. These terms are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention. In addition, the terms "first," "second," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0039] like Figures 1 to 2 As shown, this embodiment proposes a continuous polishing device for 3C product processing, including a base 1. Symmetrically arranged support legs 2 are installed on both sides of the top edge of the base 1. Movable handles 3 are rotatably connected to the top of the support legs 2 via rotating sleeves 201. Fixed plates 4 with identical structures are installed at opposite ends of the two sets of movable handles 3. Support frames 401 are installed in the middle of the opposite surfaces of the two sets of fixed plates 4. Limiting components 5 are symmetrically arranged on both sides of the fixed plates 4 located on the surfaces of the support frames 401. A box 6 is installed on the back side wall of the base 1 via support columns 13. A driving mechanism 7 is installed inside the box 6. A connecting column 9 is installed at the outer bottom end of the driving mechanism 7 via a rotating component 8. A polishing plate 10 is installed at the bottom of the connecting column 9, and the polishing plate 10 is located directly above the two sets of fixed plates 4.

[0040] First, the panels of the two sets of 3C products to be processed are fixed to the upper and lower sides of the fixing plate 4 by the limiting component 5. Then, the drive mechanism 7 works in conjunction with the rotating component 8 to drive the polishing plate 10 to rotate back and forth on the panel surface in a small amplitude, which is convenient for polishing the panel surface in different directions and avoids the appearance of scratches in more than one direction when polishing only in one direction. After the upper product panel is polished, the fixing plate 4 can be flipped by the movable handle 3 to flip the unpolished product panel to the upper side for further polishing. At this time, the processed product panel flipped to the lower side is removed and other unpolished product panels are fixed on again. By repeating this cycle, multiple sets of panels can be continuously polished by flipping the fixing plate 4, without having to remove the polished panel and fix other panels after it is finished, which saves a lot of polishing time.

[0041] like Figure 5 and Figure 6 As shown, in a preferred embodiment, based on the above method, the movable handle 3 further includes a fixed cylinder 31 rotatably connected to the inner side of the rotating sleeve 201, a slidably connected handle 32 inside the fixed cylinder 31, and a retaining plate 33 installed on the outer wall of the handle 32. One end face of the fixed cylinder 31 is fixedly connected to the side wall of the fixed plate 4, and one end of the handle 32 located inside the fixed cylinder 31 is also fixedly connected to the side wall of the fixed plate 4. A retaining groove 311 that cooperates with the retaining plate 33 is also provided on the edge of the fixed cylinder 31 away from the fixed plate 4.

[0042] After the product panel on the upper side of the fixing plate 4 is polished, first pull the handle 32 out of the fixing cylinder 31 and make the clamping plate 33 disengage from the slot 311 on the fixing cylinder 31. At this time, the handle 32 can be rotated to make the fixing plate 4 flip 90 degrees, flip the product panel on the upper side of the fixing plate 4 to the lower side, and flip the product panel on the lower side of the fixing plate 4 to the upper side. Then, insert the handle 32 back into the fixing cylinder 31 and let the clamping plate 33 snap into the slot 311 again to limit the handle 32. At this time, the unpolished product panel can continue to be processed. During the polishing of the upper product panel, the worker can use this time to remove the product panel that has been flipped to the lower side and then fix the next set of unprocessed product panels. This process can be repeated in sequence, so that it is not necessary to disassemble and fix other unprocessed panels after the polishing of a set of product panels is completed, thus saving a lot of polishing time.

[0043] like Figure 5 and Figure 6As shown, in a preferred embodiment, based on the above method, the throttle 32 further includes a rotating cylinder 321 slidably connected inside the fixed cylinder 31 and a sliding rod 322 slidably connected inside the rotating cylinder 321. The end of the sliding rod 322 away from the rotating cylinder 321 is fixedly connected to the side wall of the fixed plate 4. The outer wall of the sliding rod 322 located inside the rotating cylinder 321 is provided with a protrusion 3221, and the inner wall of the rotating cylinder 321 is provided with a groove 3211 that cooperates with the protrusion 3221.

[0044] When the throttle 32 is pulled out of the fixed cylinder 31, the rotating cylinder 321 will slide through the slide groove 3211 and the protrusion 3221 on the slide rod 322, which makes it easy for the rotating cylinder 321 to be pulled out. The protrusion 3221 can prevent the slide rod 322 from separating from the rotating cylinder 321. Moreover, when the rotating cylinder 321 is rotated, the protrusion 3221 can also drive the slide rod 322 to rotate together, thus driving the fixed plate 4 and the product panel to flip.

[0045] Among them, a fixing ring 3222 is installed on the inner wall of the fixing cylinder 31, the sliding rod 322 is slidably connected to the fixing ring 3222, and a first spring 12 is connected in series on the rod wall of the sliding rod 322 located between the fixing plate 4 and the fixing ring 3222.

[0046] When rotating the drum 321 and the slide bar 322, the slide bar 322 will also drive the first spring 12 to twist. The slide bar 322 can be limited by the clamping plate 33. When the drum 321 is pulled out again and the clamping plate 33 is disengaged from the clamping slot 311, the first spring 12 will be released and the slide bar 322 will automatically reverse and reset. Therefore, the worker does not need to rotate the drum 321 again, saving time and manpower.

[0047] like Figure 3 As shown, in a preferred embodiment, based on the above method, the limiting component 5 further includes a pressure block 51 symmetrically arranged on the upper and lower surfaces of the fixing plate 4 and a second spring 52 connected between the pressure block 51 and the back of the fixing plate 4, and the end of the pressure block 51 away from the second spring 52 is an inclined triangular structure.

[0048] The product panel is pressed directly onto the support frame 401 on the fixing plate 4. When the bottom of the product panel contacts the pressure block 51, it will press it against the back of the fixing plate 4 and stretch the second spring 52. When the bottom edge of the product panel abuts against the surface of the support frame 401, the second spring 52 will be released and the pressure block 51 will rebound and return to the upper edge of the upper surface of the product panel, thereby blocking and fixing the product panel.

[0049] like Figure 4As shown, in a preferred embodiment, based on the above method, the support frame 401 is further provided with a clamping assembly 11 inside. The clamping assembly 11 includes a screw 111 threadedly connected to the side wall of the support frame 401, a push block 112 slidably connected to the inner wall of the support frame 401, a pressure rod 113 slidably connected to the top of the support frame 401, and a pressure plate 114 installed on the top of the pressure rod 113. The end of the screw 111 located inside the support frame 401 is rotatably connected to the side wall of the push block 112, the bottom of the pressure rod 113 is slidably connected to the surface of the push block 112, and the surface of the fixing plate 4 is also provided with a groove 402 slidably connected to the pressure plate 114.

[0050] If the product panel is too thin to be pressed by the pressure block 51, the screw 111 can be rotated to move the push block 112. The push block 112 will continuously push the pressure rod 113 up, thereby pushing the pressure plate 114 to abut against one side of the pressure block 51 on the back of the product panel, and the panel can be tightly clamped between the pressure plate 114 and the pressure block 51, which is convenient for fixing product panels of different thicknesses.

[0051] like Figure 9 As shown, in a preferred embodiment, based on the above method, the drive mechanism 7 further includes a motor 71 mounted on the top wall of the inner box 6, a half gear 72 connected to the output end of the motor 71, a crank rod 73 rotatably connected to the top wall of the inner box 6, a full gear 74 fixedly sleeved on the inner side wall of the crank rod 73 located in the inner side wall of the box 6, and a third spring 75 connected in series on the wall between the top wall of the inner box 6 and the upper surface of the full gear 74.

[0052] Once the product panel is fixed in place, the motor 71 can be started to drive the half gear 72 to rotate. When the toothed side of the half gear 72 contacts the full gear 74, it will cause the full gear 74 and the crank 73 to rotate and the third spring 75 to twist. When the toothless side of the half gear 72 contacts the full gear 74, the third spring 75 will be released from its force and drive the full gear 74 and the crank 73 to reverse and reset. Therefore, the crank 73 will drive the polishing plate 10 to rotate back and forth in two directions, which is convenient for polishing the surface of the product panel in different directions and prevents the panel surface from having a large number of scratches in one direction due to polishing in only one direction.

[0053] like Figure 1 As shown, in a preferred embodiment, based on the above method, the rotating assembly 8 further includes multiple sets of connecting rods 83 equidistantly mounted on the outer wall of the housing 6, a gear ring 81 connected to the bottom of the multiple sets of connecting rods 83, and a gear disk 82 disposed at the bottom end of the crank 73, wherein the gear disk 82 and the gear ring 81 mesh with each other, and the top of the support column 13 is connected to the rod wall of a set of connecting rods 83.

[0054] When the crank 73 rotates, it will drive the gear plate 82 to rotate along the inner side of the gear ring 81, thereby driving the polishing plate 10 to rotate slightly through the connecting column 9, which is convenient for back-and-forth polishing of the product panel surface and avoids the formation of scratches in the same direction when polishing in only one direction.

[0055] like Figure 7 and Figure 8 As shown, in a preferred embodiment, based on the above method, the connecting column 9 further includes a connecting cylinder 91 disposed at the bottom of the gear plate 82, a lifting rod 92 slidably connected inside the connecting cylinder 91, a fourth spring 93 installed between the top of the lifting rod 92 and the inner top wall of the connecting cylinder 91, and a bolt 94 threadedly connected between the connecting cylinder 91 and the lifting rod 92, and the outer walls of the connecting cylinder 91 and the lifting rod 92 are provided with communicating screw holes 911;

[0056] When the product panel needs to be polished, first unscrew the bolt 94 between the connecting cylinder 91 and the hanging rod 92. At this time, the fourth spring 93 will drive the hanging rod 92 to bounce downward and abut against the surface of the product panel, so that the polishing plate 10 can polish the product panel when it rotates slightly.

[0057] The polishing plate 10 includes a mounting base 101 disposed at the bottom of the rod 92, and a polishing belt 102 connected to the bottom of the mounting base 101 by a connecting block 103 and a nut.

[0058] The polishing belt 102 can be disassembled by connecting block 103 and nut, making it convenient to replace polishing belts 102 of different specifications to perform coarse polishing and fine polishing on the product panel in sequence.

[0059] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described herein. Although the present invention has been described in detail with reference to the above embodiments, the present invention is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present invention, as well as all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present invention.
