Description

Technical Field

[0001] This utility model belongs to the field of sandblasting technology, specifically relating to a material turning device for a sandblasting machine. Background Technology

[0002] The application of sandblasting in automotive capacitors is mainly to improve the adhesion and corrosion resistance of the capacitor surface. Through sandblasting, an ideal roughness can be created on the capacitor surface, removing impurities and oxide layers, thereby increasing the adhesion of the coating, improving the corrosion resistance of the capacitor, extending its service life, and ensuring the stable performance of the capacitor in various environments.

[0003] To improve the performance of sandblasting, the outer circumferential surface of the cylindrical capacitor core needs to be sandblasted. In existing sandblasting mechanisms, the capacitor core is conveyed to the sandblasting station by the conveying mechanism, and sandblasting glass beads are sprayed onto the surface of the capacitor by the sandblasting machines around it, thus completing the sandblasting process.

[0004] Existing sandblasting methods have blind spots during sandblasting because the capacitor core cannot rotate, resulting in missed areas on the outer circumference of the cylindrical capacitor core. This leads to subsequent rework and increases costs. Utility Model Content

[0005] This utility model provides a material turning device for a sandblasting machine, which solves the defect of missed spraying caused by the existence of blind spots in the sandblasting mechanism.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is: a material turning device for a sandblasting machine, comprising:

[0007] A material turning assembly, comprising a height-adjustable material turning frame and material turning rollers rotatably mounted between the material turning frames and spaced apart, wherein the material turning rollers rotate in the same direction;

[0008] The pressing assembly includes a pressing frame that is height-adjustably disposed above the turning frame and a pressing rod that is rotatably mounted on the bottom of the pressing frame and cooperates with the turning roller.

[0009] Optimally, the turning roller includes insert rods rotatably mounted between the turning frames and inserted sequentially, and a sleeve fixed to the top of the turning frame and extending toward the side near the insert rods, the sleeve being fitted onto the insertion point of two adjacent insert rods.

[0010] Optimally, the turning roller further includes an insertion groove formed at one end of the insertion rod, an insertion part integrally connected to the other end of the insertion rod and cooperating with the insertion groove, and a bearing sleeve fitted on the insertion rod, wherein the outer diameter of the bearing sleeve is equal to the outer diameter of the sleeve.

[0011] Optimally, the material turning assembly further includes a first support frame, a first guide rod that is vertically and flexibly inserted into the first support frame, and a first lifting mechanism fixed on the first support frame and used to drive the first guide rod to rise and fall, wherein the first guide rod is fixed to the top of the material turning frame.

[0012] Optimally, the pressing assembly further includes a second support frame, a second guide rod that is vertically and flexibly inserted into the second support frame, and a second lifting mechanism fixed on the second support frame and used to drive the second guide rod to rise and fall, wherein the pressing frame is fixed to the bottom of the second guide rod.

[0013] Optimally, the material turning assembly further includes a first gear mounted on one end of the insert rod, a first synchronous belt wound around the first gear, a first motor fixed on one side of the material turning frame, a second gear mounted on the output end of the first motor and one end of any insert rod, and a second synchronous belt wound around the second gear.

[0014] Optimally, the first lifting mechanism includes a first lead screw rotatably mounted in the first support frame, a first lifting plate fixed to the first guide rod and cooperating with the first lead screw, a third gear fitted on the top of the first lead screw, a third synchronous belt wound around the third gear, and a drive unit fixed to one side of the first support frame for driving the first lead screw to rotate.

[0015] Optimally, the drive unit includes an adjustment plate adjustablely disposed on one side of the first support frame, a small gear rotatably mounted on the top of the adjustment plate, a large gear sleeved on the top of the first lead screw, and a drive belt wound around the small gear and the large gear.

[0016] Optimally, the first lifting mechanism further includes a clamping frame fixed to the top of the first support frame and rollers rotatably mounted between the clamping frames, the rollers abutting against the third synchronous belt.

[0017] Ideally, the second lifting mechanism includes a second lead screw rotatably mounted within the second support frame and a second lifting plate fixed to the second guide rod and cooperating with the second lead screw.

[0018] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0019] This utility model relates to a turning device for a sandblasting machine. By setting a turning roller on the turning frame, the turning roller drives the cylindrical capacitor core to rotate and turn over, avoiding blind spots during sandblasting. By setting a pressing component, the component presses against the surface of the capacitor core during turning, preventing the capacitor core from falling off. This improves sandblasting efficiency, avoids blind spots, eliminates the need for rework of the sandblasted capacitor core, and reduces production costs. Attached Figure Description

[0030] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0031] like Figure 1 The diagram shows the structure of the turning device for the sandblasting machine of this utility model. This turning device is usually used to turn the cylindrical capacitor core over so as to avoid sandblasting blind spots on the circumference of the cylindrical capacitor core during sandblasting, thereby improving the pass rate of the finished product after sandblasting and avoiding rework defects.

[0032] The flipping device includes a flipping assembly and a pressing assembly. The capacitor core to be sandblasted is placed on the flipping assembly, which drives the cylindrical capacitor core to flip over. Then, the sandblasting machine on one side of the flipping assembly completes the sandblasting treatment on the surface of the cylindrical capacitor core. The pressing assembly is located above the flipping assembly. During sandblasting, the pressing assembly presses down on the surface of the cylindrical capacitor core, preventing the capacitor core from falling off the flipping assembly during flipping.

[0033] like Figure 2 The diagram shows the structure of the material-turning assembly, which includes a first support frame, a material-turning frame 1, a material-turning roller, and a first lifting mechanism. (Specifically, during sandblasting, the sandblasting machine will spray sandblasting glass beads. To prevent the sandblasting glass beads from scattering and endangering the safety of surrounding personnel, the entire sandblasting process is completed inside the control box. The control box is a box structure welded from aluminum profiles and metal plates, and its interior is hollow. The material-turning assembly and the material-pressing assembly are both located inside the control box. The sandblasting machine is also located inside the control box, and the sandblasting direction of the sandblasting machine faces the material-turning assembly.)

[0034] The first support frame is fixed to the top of the control box. Its main function is to provide support and fixation. Figure 4As shown, the first support frame includes a first lower support plate 15, a first column 17, and a first upper support plate 16. The first lower support plate 15 is fixed to the top of the control box by screws. There are at least two first columns 17, which are fixed to the top of the first lower support plate 15 by welding and are spaced apart. The spaced first columns 17 provide clearance for the installation of the first lifting plate 20.

[0035] The first upper support plate 16 is fixed to the top of the first column 17 by welding. The first lower guide sleeve 18 is embedded in the first lower support plate 15. The first upper guide sleeve 19 is embedded in the first upper support plate 16. The first guide rod 14 passes through the first upper guide sleeve 19 and the first lower guide sleeve 18 and extends into the control box (the top of the control box has a through groove, and the size of the through groove is smaller than the size of the first lower support plate 15, which can both fix the first lower support plate 15 and allow the first guide rod 14 to pass through the control box and extend into the inside of the control box).

[0036] The two ends of the first lead screw 21 are respectively mounted on the first lower support plate 15 and the first upper support plate 16 via bearings, and the first lead screw 21 is vertically arranged (i.e., the first lead screw 21 is parallel to the first guide rod 14). The first lifting plate 20 is fixed on the first guide rod 14 and cooperates with the first lead screw 21 (specifically, the first lifting plate 20 has a through hole that cooperates with the first guide rod 14, the first guide rod 14 passes through the through hole of the first lifting plate 20, and then the first lifting plate 20 and the first guide rod 14 are fixed together by welding; a lead screw nut is fitted on the first lead screw 21, and the lead screw nut is fixed on the first lifting plate 20 by screw fastening).

[0037] When the first lead screw 21 rotates, it drives the first lifting plate 20 to move up and down. The first lifting plate 20 then drives the first guide rod 14 to move up and down, ultimately causing the tilting frame 1 at the bottom of the first guide rod 14 to move up and down. The tilting frame 1 then drives the cylindrical capacitor cores on it to move up and down, thus accommodating surface sandblasting treatment of capacitor cores of different diameters. By setting a first lower guide sleeve 18 and a first upper guide sleeve 19 that cooperate with the first guide rod 14, the lifting movement of the first guide rod 14 is guided, improving its stability.

[0038] The third gear 29 is keyed and mounted on top of the first lead screw 21, and the third synchronous belt 30 is wound around the third gear 29. To ensure smooth lifting and lowering of the tilting frame 1, a set of first support frames (i.e., two first support frames, which together lift the tilting frame 1) is required. When the drive unit drives the first lead screw 21 to rotate, the third gear 29 and the third synchronous belt 30 transmit power to the other set of first support frames, thereby driving the first lead screw 21 on the other set of first support frames to rotate synchronously.

[0039] To prevent slippage between the third gear 29 and the third synchronous belt 30, which would cause the first lead screws 21 on both sides to move asynchronously, the third synchronous belt 30 is a toothed belt, and the third gear 29 is a synchronous pulley (a synchronous pulley is a part with equally spaced sawtooth gears on its outer circumferential surface, which can mesh with the tooth grooves of the toothed belt to transmit motion and power and prevent slippage).

[0040] The folding plate 44 is fixed to the top of the first upper support plate 16 by screws or welding. The mounting plate 45 is fixed to the side of the folding plate 44 near the third synchronous belt 30. The roller 46 is rotatably installed between the folding plate 44 and the mounting plate 45 and abuts against the outside of the third synchronous belt 30 to improve the stability of the rotation of the third synchronous belt 30. (Specifically, the rotating shaft passes through the roller 46 with an interference fit and is coaxial with the roller 46. The two ends of the rotating shaft are respectively installed between the folding plate 44 and the mounting plate 45 through bearings. When the third synchronous belt 30 rotates, it drives the roller 46 to rotate synchronously under the action of friction.)

[0041] The first extension plate 22 is fixed to one side of the first upper support plate 16 by welding or screw fastening. The adjusting plate 23 is adjustablely fixed to the top of the first extension plate 22 (specifically, the adjusting plate 23 has a through adjusting groove 24, which is rounded rectangular, and the fastening bolt passes through the adjusting groove 24 to fix it to the top of the first extension plate 22). The through groove passes through the first extension plate 22, and the second motor 25 is fixed to the bottom of the adjusting plate 23 by screw fastening. The through groove in the first extension plate 22 provides clearance for the installation of the second motor 25. By moving the position of the adjusting plate 23, the position of the second motor 25 can be adjusted outward as appropriate, thereby tensioning the drive belt 28.

[0042] The small gear 26 is fixed to the motor shaft of the second motor 25 by a key connection, and the large gear 27 is fixed to the first lead screw 21 by a key connection. The drive belt 28 is wound around the small gear 26 and the large gear 27. The second motor 25 drives the small gear 26 to rotate, and the drive belt 28 drives the large gear 27 to rotate, which in turn drives the first lead screw 21 to rotate.

[0043] The diameter of the pinion 26 is smaller than that of the gear 27 to reduce the rotational speed of the first lead screw 21, thereby reducing the lifting speed of the tilting frame 1 and improving the stability of the lifting motion.

[0044] To prevent slippage between the pinion 26, the gear 27, and the drive belt 28, the drive belt 28 is a toothed belt, and the gear 27 and the pinion 26 are synchronous pulleys (a synchronous pulley is a part with equally spaced sawtooth gears on its outer circumferential surface, which can mesh with the tooth grooves of the toothed belt to transmit motion and power and prevent slippage).

[0045] The fixing frame 13 is fixed to the bottom of the first guide rod 14 by screws. The flipping frame 1 is fixed to the bottom of the fixing frame 13 by screws. When the first lifting mechanism drives the first guide rod 14 to rise and fall, it will drive the flipping frame 1 and the cylindrical capacitor core on it to rise and fall synchronously (the first support frame is fixed to the top of the control box, so the first support frame is located on the outside of the control box, while the first guide rod 14 and the flipping frame 1 are placed on the inside of the control box).

[0046] There are two turning rollers, with each end rotatably mounted on the turning frame 1 via bearings (specifically, the two turning rollers are set in parallel, and the cylindrical capacitor core to be sandblasted is placed on the two turning rollers, with the circumferential surface of the cylindrical capacitor core abutting against the turning rollers. When the turning rollers rotate, they drive the cylindrical capacitor core to rotate, and then the sandblasting machine on one side sandblasts the outer circumferential surface of the cylindrical capacitor core. Rotating the cylindrical capacitor core during sandblasting avoids sandblasting blind spots).

[0047] like Figure 5 As shown, each turning roller is formed by inserting multiple rods 2 sequentially. The insertion groove 3 is opened at one end of the rod 2, and the insertion part 4 is integrally connected to the other end of the rod 2 and cooperates with the insertion groove 3. The insertion parts 4 of two adjacent rods 2 are inserted into each other with the insertion groove 3, thus forming a turning roller by inserting multiple rods 2 together.

[0048] The sleeve 6 is fixed to the inside of the turning frame 1 by a fixing plate, and the insertion points of two adjacent insertion rods 2 are inserted into the sleeve 6. The sleeve 6 supports the insertion points to prevent the insertion points of the insertion rods 2 from being misaligned and falling apart when they rotate.

[0049] A turning roller is formed by connecting multiple insert rods 2, which, together with a sleeve 6, improves the structural strength of the insert rods 2. By shortening the length of a single insert rod 2, the middle part of the insert rod 2 is prevented from drooping downwards under the action of gravity, thus affecting the turning of the cylindrical capacitor core. A bearing sleeve 5 is interference-fitted onto the insert rod 2, and the outer diameter of the bearing sleeve 5 is equal to the outer diameter of the sleeve 6, facilitating the forward pushing of the cylindrical capacitor core.

[0050] When the insertion rod 2 rotates, it will drive the bearing sleeve 5 to rotate synchronously, thereby flipping the cylindrical capacitor core on it. The sleeve 6 does not rotate. The sleeve 6 supports the insertion points of the two adjacent insertion rods 2 (to improve the stability of rotation, bearings are installed on both sides inside the sleeve 6, and the two ends of the two adjacent insertion rods 2 are respectively inserted into the bearings of the sleeve 6 and then inserted together).

[0051] like Figure 3As shown, the first gear 9 is fixed to one end of the insertion rod 2 by a key connection, and the first synchronous belt 10 is wound around the first gear 9. By setting the first gear 9 and the first synchronous belt 10, the insertion rod 2 can rotate in the same direction. To avoid slippage between the first gear 9 and the first synchronous belt 10, the first synchronous belt 10 is a toothed belt, and the first gear 9 is a synchronous pulley (a synchronous pulley is a part with equally spaced sawtooth gears on its outer circumferential surface, which can mesh with the tooth grooves of the toothed belt to transmit motion and power and avoid slippage).

[0052] The fixing plate 7 is fixed to one side of the flipping frame 1 by screws, and the first motor 8 is fixed to the side of the fixing plate 7 near the flipping frame 1 by screws. The motor shaft of the first motor 8 passes through the fixing plate 7, and the second gear 11 is fixed to one end of the motor shaft of the first motor 8 and the insert rod 2 by a key connection. The second synchronous belt 12 is wound around the second gear 11. The first motor 8 drives the second gear 11 to rotate, which in turn drives the two flipping rollers to rotate, thereby rotating the cylindrical capacitor core on them. Finally, the surface of the capacitor core is sandblasted by a sandblasting machine on one side.

[0053] To prevent slippage between the second gear 11 and the second synchronous belt 12, the second synchronous belt 12 is a toothed belt, and the second gear 11 is a synchronous pulley (a synchronous pulley is a part with equally spaced sawtooth gears on its outer circumferential surface, which can mesh with the tooth grooves of the toothed belt to transmit motion and power and prevent slippage).

[0054] During actual sandblasting, the tilting frame 1 is suspended inside the control box by a set of first support frames. Driven by the first lifting mechanism, the tilting frame 1 can be adjusted to meet the surface sandblasting treatment of cylindrical capacitor cores of different diameters. (When facing capacitor cores of different diameters, by adjusting the height of the tilting frame 1, it is ensured that the sandblasting machine on one side can spray the sandblasting glass beads onto the surface of the capacitor core.)

[0055] The control box has an operation window on the front side, which connects the inner and outer spaces. The robot or operator places the capacitor core to be sandblasted on the turning roller. The turning roller drives the capacitor core to rotate, and the sandblasting machine on one side completes the sandblasting work on the surface of the capacitor core.

[0056] like Figure 6 , 7The diagram shows the structure of the pressing assembly. The pressing assembly is positioned above the flipping assembly. During sandblasting, it presses the cylindrical capacitor core onto the surface, preventing the core from falling off the flipping assembly during flipping. The pressing assembly includes a second support frame, a second lifting mechanism, and a pressure rod 43. The second support frame is fixed to the top of the control box and primarily serves a supporting and fixing function. It includes a second lower support plate 31, second columns 33, and a second upper support plate 32. The second lower support plate 31 is fixed to the top of the control box with screws. There are at least two second columns 33, which are welded to the top of the second lower support plate 31 and spaced apart. The spacing of the second columns 33 provides clearance for the installation of the second lifting plate 36.

[0057] The second upper support plate 32 is fixed to the top of the second column 33 by welding. The second lower guide sleeve 34 is embedded in the second lower support plate 31. The second upper guide sleeve 35 is embedded in the second upper support plate 32. The second guide rod 39 passes through the second upper guide sleeve 35 and the second lower guide sleeve 34 and extends into the control box (the top of the control box has a through groove, and the size of the through groove is smaller than the size of the second lower support plate 31, which can both fix the second lower support plate 31 and allow the second guide rod 39 to pass through the control box and extend into the inside of the control box).

[0058] The two ends of the second lead screw 37 are respectively mounted on the second lower support plate 31 and the second upper support plate 32 via bearings, and the second lead screw 37 is vertically arranged (i.e., the second lead screw 37 is parallel to the second guide rod 39). The second lifting plate 36 is fixed on the second guide rod 39 and cooperates with the second lead screw 37 (specifically, the second lifting plate 36 has a through hole that cooperates with the second guide rod 39, the second guide rod 39 passes through the through hole of the second lifting plate 36, and then the second lifting plate 36 and the second guide rod 39 are fixed together by welding; a lead screw nut is fitted on the second lead screw 37, and the lead screw nut is fixed on the second lifting plate 36 by screw fastening).

[0059] When the second lead screw 37 rotates, it will drive the second lifting plate 36 to move up and down, which in turn will drive the second guide rod 39 to move up and down, and finally drive the pressure rod 43 at the bottom of the second guide rod 39 to move up and down. The pressure rod 43 presses on the surface of the cylindrical capacitor core, preventing the cylindrical capacitor core from falling off when rotating and sandblasting.

[0060] The third motor 38 is fixed to the top of the second upper support plate 32 by screw fastening. The output shaft of the third motor 38 is connected to the second lead screw 37. The third motor 38 drives the second lead screw 37 to rotate. (The second support frame is fixed to the top of the control box, so the second support frame is located on the outside of the control box, while the second guide rod 39 and the pressure rod 43 are located on the inside of the control box.)

[0061] like Figure 8 As shown, a second extension plate 40 is fixed to the bottom of the second guide rod 39, and the second extension plate 40 extends towards the side closer to the flipper 1, ensuring that the pressure rod 43 can press directly above the cylindrical capacitor core. The fixing post 41 is fixed to the side of the second extension plate 40 away from the second guide rod 39, and fixing blocks 42 are fixed to both ends of the fixing post 41. The two ends of the pressure rod 43 are rotatably mounted on the bottom of the fixing blocks 42 through bearings.

[0062] When the sandblasting machine sandblasts the surface of the cylindrical capacitor core, the pressure rod 43 descends and presses against the surface of the cylindrical capacitor core. When the cylindrical capacitor core rotates, the pressure rod 43 rotates under the action of friction. Under the action of the pressure rod 43, the cylindrical capacitor core is prevented from falling off.

[0063] This utility model relates to a turning device for a sandblasting machine. By setting a turning roller on the turning frame 1, the turning roller drives the cylindrical capacitor core to rotate and turn over, thus avoiding blind spots during sandblasting. The height of the turning frame 1 is adjusted by setting a first lifting mechanism to meet the surface sandblasting needs of capacitor cores of different diameters. By setting a pressing component, the component presses against the surface of the capacitor core during the turning process, preventing the capacitor core from falling off.

[0064] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
