Description

Technical Field

[0001] This invention belongs to the field of sandblasting machine technology, and specifically relates to a sandblasting machine for capacitor cores. 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] Currently, most sandblasting operations still rely on manual hand-held sandblasting guns. Manual sandblasting is inefficient, cannot meet the production requirements of large-volume products, and there is also the possibility of missed areas, which affects the pass rate of finished products. In addition, the labor costs are relatively high. Summary of the Invention

[0004] This invention provides a sandblasting machine for capacitor cores, which solves the problems of low efficiency and high cost of manual sandblasting.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is: a sandblasting machine for capacitor cores, comprising:

[0006] The flipping structure includes a height-adjustable flipping frame and a flipping assembly fixed inside the flipping frame. The flipping assembly is used to axially flip the capacitor core on the flipping frame.

[0007] A pushing structure is provided below the flipping frame and is used to push the capacitor core that is axially flipped on the flipping frame.

[0008] A sandblasting structure, comprising a sandblasting gun adjustablely disposed on one side of the flipping frame, the sandblasting gun sandblasting the circumferential surface of the capacitor core.

[0009] Ideally, the material turning assembly includes turning rollers rotatably mounted between the material turning frames and spaced apart, the turning rollers rotating in the same direction.

[0010] Optimally, the pushing structure includes a pushing frame, a first pushing wheel rotatably mounted on one side of the pushing frame, a second pushing wheel adjustablely disposed on the other side of the pushing frame, a pushing belt wound around the first and second pushing wheels, and a pushing assembly fixed to the outside of the pushing belt and extending to the turning roller. The pushing assembly is used to push the capacitor core that is axially rotated on the turning roller.

[0011] Optimally, the pushing assembly includes a pushing rod fixed to the outside of the pushing belt and a follower sleeve rotatably mounted on one side of the pushing rod;

[0012] When the follower sleeve pushes the axially rotating capacitor core, the follower sleeve and the capacitor core are coaxially arranged.

[0013] Optimally, the pushing structure further includes a limiting plate fixed to the outside of the pushing belt and fixed to the pushing rod, a limiting component fixed to the inside of the pushing frame and used to support the limiting plate, and an adjusting component fixed to one side of the pushing frame and used to adjust the second pushing wheel.

[0014] Optimally, the limiting component includes a fixing plate fixed inside the pusher frame, a first limiting rod passing through the fixing plate and located above the pusher belt, a limiting groove formed between the first limiting rods, and a second limiting rod passing through the fixing plate and located below the pusher belt.

[0015] When the pushing assembly rotates to above the pushing belt, the limiting plate is placed in the limiting groove;

[0016] When the pushing assembly rotates to the position below the pushing belt, the limiting plate abuts against the second limiting rod.

[0017] Optimally, the adjustment assembly includes a slide plate fixed at intervals on one side of the pusher frame, a slide groove formed on the opposite side of the slide plate, a second adjustment plate slidably disposed in the slide groove, and a locking mechanism fixed on the pusher frame for locking the second adjustment plate, wherein the second pusher wheel is rotatably mounted on the second adjustment plate.

[0018] Optimally, the locking mechanism includes a stop plate fixed to the side of the pusher frame near the slide plate, a locking plate fixed to the second adjusting plate, an adjusting bolt screwed through the locking plate and abutting against one side of the stop plate, and an adjusting nut screwed onto the adjusting bolt, wherein the adjusting nut abuts against the side of the locking plate away from the stop plate.

[0019] Optimally, it also includes a pressing structure, which includes a pressing frame that is height-adjustably disposed above the flipping frame and a pressing rod that is rotatably mounted at the bottom of the pressing frame, wherein the pressing rod abuts against the top of the capacitor core when the sandblasting gun sandblasts the circumferential surface of the capacitor core.

[0020] 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.

[0021] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art:

[0022] The present invention relates to a sandblasting machine for capacitor cores. During sandblasting, the capacitor core is placed on a tilting structure, which drives the capacitor core to rotate axially. At the same time, a pushing structure pushes the axially rotating capacitor core forward. During the axial rotation and movement, the capacitor core passes through parallel sandblasting guns to achieve surface sandblasting treatment. The invention features a high degree of automation, avoids missed areas, improves sandblasting efficiency and product qualification rate, reduces labor input, and saves costs.

[0043] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0044] like Figure 1 The diagram shows a schematic of the structure of the sandblasting machine for capacitor cores according to the present invention. This sandblasting machine is typically used to sandblast the surface of cylindrical capacitor cores to remove contaminants and defective layers from the surface of the capacitor cores, thereby improving the surface quality and reliability of the capacitor cores.

[0045] The sandblasting machine includes a tilting structure 1, a pushing structure 2, a pressing structure 3, and a sandblasting structure 4. The cylindrical capacitor core to be sandblasted is placed on the tilting structure 1. Under the combined action of the pushing structure 2 and the tilting structure 1, the cylindrical capacitor core moves linearly towards the sandblasting station while rotating around its own axis. During the rotation and movement process, the surface is sandblasted by the sandblasting gun 407.

[0046] The sandblasting structure 4 is located on one side of the flipping structure 1. The sandblasting structure 4 sprays sandblasting glass beads to complete the sandblasting work on the surface of the capacitor core. During sandblasting, the pressing structure 3 descends and presses against the top of the capacitor core to prevent the capacitor core from falling off the flipping structure 1.

[0047] like Figure 2 The diagram shows the structure of the material-turning structure 1. The material-turning structure 1 includes a first support frame, a material-turning frame 101, a material-turning roller, and a first lifting mechanism, etc. (Specifically, during sandblasting, the sandblasting gun 407 will spray sandblasting glass beads. To avoid the sandblasting glass beads 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. Its interior is hollow. The material-turning structure 1, the material-pushing structure 2, the material-pressing structure 3, and the sandblasting structure 4 are all set inside the control box, and the sandblasting direction of the sandblasting structure 4 faces the material-turning structure 1).

[0048] The first support frame is fixed to the top of the control box. Its main function is to provide support and fixation. Figure 5 As shown, the first support frame includes a first lower support plate 114, a first column 116, and a first upper support plate 115. The first lower support plate 114 is fixed to the top of the control box by screws. There are at least two first columns 116, which are fixed to the top of the first lower support plate 114 by welding and are spaced apart. The spaced first columns 116 provide clearance for the installation of the first lifting plate 119.

[0049] The first upper support plate 115 is fixed to the top of the first column 116 by welding. The first lower guide sleeve 117 is embedded in the first lower support plate 114. The first upper guide sleeve 118 is embedded in the first upper support plate 115. The first guide rod 113 passes through the first upper guide sleeve 118 and the first lower guide sleeve 117 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 114, which can satisfy the fixing of the first lower support plate 114, and at the same time, the first guide rod 113 can pass through the control box and extend into the interior of the control box).

[0050] The two ends of the first lead screw 120 are respectively mounted on the first lower support plate 114 and the first upper support plate 115 via bearings, and the first lead screw 120 is vertically arranged (i.e., the first lead screw 120 is parallel to the first guide rod 113). The first lifting plate 119 is fixed on the first guide rod 113 and cooperates with the first lead screw 120 (specifically, the first lifting plate 119 has a through hole that cooperates with the first guide rod 113, the first guide rod 113 passes through the through hole of the first lifting plate 119, and then the first lifting plate 119 and the first guide rod 113 are fixed together by welding; a lead screw nut is fitted on the first lead screw 120, and the lead screw nut is fixed on the first lifting plate 119 by screw fastening).

[0051] When the first lead screw 120 rotates, it drives the first lifting plate 119 to move up and down. The first lifting plate 119 then drives the first guide rod 113 to move up and down, ultimately causing the tilting frame 101 at the bottom of the first guide rod 113 to move up and down. The tilting frame 101 then drives the cylindrical capacitor cores on it to move up and down, thus accommodating surface sandblasting of capacitor cores of different diameters (ensuring the core centers remain on a central line when switching between different diameter capacitor cores, improving the sandblasting effect). By setting a first lower guide sleeve 117 and a first upper guide sleeve 118 that cooperate with the first guide rod 113, the lifting movement of the first guide rod 113 is guided, improving its stability.

[0052] The third gear 128 is keyed and mounted on top of the first lead screw 120, and the third synchronous belt 129 is wound around the third gear 128. To ensure smooth lifting and lowering of the tilting frame 101, a set of first support frames (i.e., two first support frames, which together lift the tilting frame 101) is required. When the drive unit drives the first lead screw 120 to rotate, the third gear 128 and the third synchronous belt 129 transmit power to the other set of first support frames, thereby driving the first lead screw 120 on the other set of first support frames to rotate synchronously.

[0053] To prevent slippage between the third gear 128 and the third synchronous belt 129, which would cause the first lead screws 120 on both sides to move asynchronously, the third synchronous belt 129 is a toothed belt, and the third gear 128 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] The clamping plate 130 is fixed to the top of the first upper support plate 115 by screws or welding. The inner support plate 131 is fixed to the side of the clamping plate 130 near the third synchronous belt 129. The roller 132 is rotatably installed between the clamping plate 130 and the inner support plate 131 and abuts against the outside of the third synchronous belt 129 to improve the stability of the rotation of the third synchronous belt 129. (Specifically, the rotating shaft passes through the roller 132 with an interference fit and is coaxial with the roller 132. The two ends of the rotating shaft are respectively installed between the clamping plate 130 and the inner support plate 131 through bearings. When the third synchronous belt 129 rotates, it drives the roller 132 to rotate synchronously under the action of friction.)

[0055] The first extension plate 121 is fixed to one side of the first upper support plate 115 by welding or screw fastening. The first adjusting plate 122 is adjustablely fixed to the top of the first extension plate 121 (specifically, the first adjusting plate 122 has a through adjusting groove 123, which is rounded rectangular, and the fastening bolt passes through the adjusting groove 123 to fix it to the top of the first extension plate 121). The through groove passes through the first extension plate 121, and the second motor 124 is fixed to the bottom of the first adjusting plate 122 by screw fastening. The through groove in the first extension plate 121 provides clearance for the installation of the second motor 124. By adjusting the position of the first adjusting plate 122, the position of the second motor 124 can be adjusted outwards appropriately, thereby tensioning the drive belt 127.

[0056] The small gear 125 is fixed to the motor shaft of the second motor 124 by a key connection, and the large gear 126 is fixed to the first lead screw 120 by a key connection. The drive belt 127 is wound around the small gear 125 and the large gear 126. The second motor 124 drives the small gear 125 to rotate, and the drive belt 127 drives the large gear 126 to rotate, which in turn drives the first lead screw 120 to rotate.

[0057] The diameter of the pinion 125 is smaller than that of the gear 126 to reduce the rotational speed of the first lead screw 120, thereby reducing the lifting speed of the tilting frame 101 and improving the stability of the lifting motion.

[0058] To prevent slippage between the pinion 125, the gear 126, and the drive belt 127, the drive belt 127 is a toothed belt, and the gear 126 and the pinion 125 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).

[0059] The fixing frame 112 is fixed to the bottom of the first guide rod 113 by screws, and the flipping frame 101 is fixed to the bottom of the fixing frame 112 by screws. When the first lifting mechanism drives the first guide rod 113 to rise and fall, it will drive the flipping frame 101 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 113 and the flipping frame 101 are located on the inside of the control box).

[0060] There are two turning rollers, with each end rotatably mounted on the turning frame 101 via bearings (specifically, the two turning rollers are arranged 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 gun 407 on one side sandblasts the outer circumferential surface of the cylindrical capacitor core. Rotating the cylindrical capacitor core during sandblasting avoids blind spots and improves the sandblasting effect).

[0061] like Figure 3 As shown, each turning roller is formed by sequentially inserting multiple rods 102. An insertion groove 103 is formed at one end of each rod 102, and an insertion part 104 is integrally connected to the other end of the rod 102 and mates with the insertion groove 103. The insertion parts 104 of two adjacent rods 102 interlock with each other in the insertion groove 103, thus forming a turning roller by interlocking multiple rods 102.

[0062] The sleeve 106 is fixed to the inside of the flipping frame 101 by a fixing plate, and the insertion points of two adjacent insertion rods 102 are inserted into the sleeve 106. The sleeve 106 supports the insertion points to prevent the insertion points of the insertion rods 102 from being misaligned and falling apart when they rotate.

[0063] A turning roller is formed by connecting multiple insert rods 102, which, together with a sleeve 106, improves the structural strength of the insert rods 102. By shortening the length of a single insert rod 102, the middle part of the insert rod 102 is prevented from drooping downwards under the influence of gravity, thus affecting the turning of the cylindrical capacitor core. A bearing sleeve 105 is interference-fitted onto the insert rod 102, and the outer diameter of the bearing sleeve 105 is equal to the outer diameter of the sleeve 106, facilitating the forward pushing of the cylindrical capacitor core (if the outer diameters of the bearing sleeve 105 and the sleeve 106 do not match, the cylindrical capacitor core will be stuck when pushed forward).

[0064] When the insertion rod 102 rotates, it drives the bearing sleeve 105 to rotate synchronously, thereby flipping the cylindrical capacitor core on it. The sleeve 106 does not rotate. The sleeve 106 supports the insertion points of two adjacent insertion rods 102 (to improve the stability of rotation, bearings are installed on both sides inside the sleeve 106, and the two ends of the two adjacent insertion rods 102 are respectively inserted into the bearings of the sleeve 106 and then inserted together).

[0065] like Figure 4 As shown, the first gear 108 is fixed to one end of the insertion rod 102 by a key connection, and the first synchronous belt 109 is wound around the first gear 108. By setting the first gear 108 and the first synchronous belt 109, the insertion rod 102 can rotate in the same direction. To prevent slippage between the first gear 108 and the first synchronous belt 109, the first synchronous belt 109 is a toothed belt, and the first gear 108 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).

[0066] The first motor 107 is fixed to one side of the flipping frame 101 by a metal plate (specifically, the metal plate is fixed to one side of the flipping frame 101 by screws or welding, and the motor housing of the first motor 107 is fixed to the metal plate by screws). The motor shaft of the first motor 107 passes through the metal plate, and the second gear 110 is fixed to one end of the motor shaft of the first motor 107 and the insertion rod 102 by a key connection. The second synchronous belt 111 is wound around the second gear 110. The first motor 107 drives the second gear 110 to rotate, which in turn drives the two flipping rollers to rotate, thereby rotating the cylindrical capacitor cores on them. Finally, the surface of the capacitor cores is sandblasted by the sandblasting gun 407 on one side.

[0067] To prevent slippage between the second gear 110 and the second synchronous belt 111, the second synchronous belt 111 is a toothed belt, and the second gear 110 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).

[0068] The pusher structure 2 is fixed inside the control box and located below the tilting frame 101. It is used to push the axially rotating capacitor core to the sandblasting station for sandblasting treatment. Figure 6 , 7 As shown, the pushing structure 2 includes a pushing frame 201, a pushing belt 212, a pushing assembly, a limiting assembly, and an adjusting assembly. The pushing frame 201 is fixed inside the control box by an aluminum profile and is located below the flipping frame 101 (specifically, the aluminum profile is fixed to the bottom of the inside of the control box by welding, and the pushing frame 201 is fixed to the top of the aluminum profile by screws).

[0069] The first pusher wheel 203 is rotatably mounted on one side of the pusher frame 201 (specifically, the first pusher wheel 203 has an axle fixed to it by a key connection, and the two ends of the axle are respectively mounted on one side of the pusher frame 201 by bearings). The third motor 202 is fixed to one side of the pusher frame 201 (specifically, the support frame is fixed to the bottom of the control box by welding, the motor housing of the third motor 202 is fixed to the top of the support frame by screws, and the output shaft of the third motor 202 is connected to the axle on the first pusher wheel 203 by a coupling. The third motor 202 drives the first pusher wheel 203 to rotate, which in turn drives the pusher belt 212 on the first pusher wheel 203 to rotate, thereby pushing the capacitor core on the turning roller toward the sandblasting station).

[0070] The second pusher wheel 207 is installed on the other side of the pusher frame 201 via an adjusting assembly (i.e., the second pusher wheel 207 is installed on the side of the pusher frame 201 away from the first pusher wheel 203), such as Figure 9 As shown, the adjustment assembly includes a slide plate 204, a slide groove 205, a second adjustment plate 206, a second pusher wheel 207, a stop plate 208, a locking plate 209, an adjustment bolt 210, and an adjustment nut 211. The slide plate 204 is fixed to the outside of the pusher frame 201 by screws, and the slide groove 205 is formed on the opposite side of the slide plate 204 (i.e., the slide groove 205 is formed on the inside of the slide plate 204).

[0071] The second adjusting plate 206 is inserted into the groove 205 of the two sliding plates 204. The sliding plates 204 support and limit the second adjusting plate 206, ensuring that the second adjusting plate 206 can only be adjusted horizontally. The second pusher wheel 207 is rotatably mounted on the second adjusting plate 206 (specifically, the second pusher wheel 207 has an axle fixed by a key connection, and the two ends of the axle are respectively mounted between the second adjusting plates 206 by bearings). By moving the second adjusting plate 206 outward, the pusher belt 212 on the first pusher wheel 203 and the second pusher wheel 207 is tensioned to prevent the pusher belt 212 from deforming and slipping due to long-term use.

[0072] To prevent slippage between the first pusher wheel 203, the second pusher wheel 207, and the pusher belt 212, the pusher belt 212 is a toothed belt, and the first pusher wheel 203 and the second pusher wheel 207 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).

[0073] The abutment plate 208 is fixed to the side of the pusher frame 201 near the second adjusting plate 206 by screws. The locking plate 209 is fixed to the second adjusting plate 206 by screws. The locking plate 209 has a threaded hole. The adjusting bolt 210 is screwed through the threaded hole on the locking plate 209 and abuts against one side of the abutment plate 208 (the adjusting bolt 210 and the abutment plate 208 are not fixedly connected, but merely abut against each other).

[0074] The adjusting nut 211 is screwed onto the adjusting bolt 210 and rests against the side of the locking plate 209 away from the abutment plate 208, locking the adjusted adjusting nut 211. In actual adjustment, first pull the second adjusting plate 206 outward until the pusher belt 212 is taut (under the action of the slide plate 204 and the slide groove 205, the second adjusting plate 206 can only be adjusted horizontally outward), then screw the adjusting bolt 210 until it rests against the side of the abutment plate 208, and screw the adjusting nut 211 until it rests against the side of the locking plate 209.

[0075] The protrusion 213 is integrally connected to the outside of the pusher belt 212, and the pusher assembly is fixed on the protrusion 213. When the pusher belt 212 rotates, it will drive the protrusion 213 to rotate synchronously, which in turn drives the pusher assembly to rotate. When the pusher assembly rotates above the pusher belt 212, the pusher assembly is in a horizontal movement state. At this time, the pusher assembly pushes the capacitor core on the turning roller to move forward to the sandblasting station.

[0076] like Figure 12 , 13 As shown, the pusher assembly includes a limiting plate 214, an insert block 215, a fixing groove 216, a pusher rod 217, a cam bearing follower 218, a cover 219, and a follower sleeve 220. The insert block 215 is integrally connected to the bottom of the limiting plate 214. The fixing groove 216 is formed inside the insert block 215 and cooperates with the protrusion 213. In actual installation, the fixing groove 216 is inserted into the protrusion 213 on the outside of the pusher belt 212, and then the limiting plate 214 is fixed to the protrusion 213 by tightening screws.

[0077] The protrusion 213 is a rectangular block. The length direction of the protrusion 213 is parallel to the width direction of the pusher belt 212. Therefore, when the limiting plate 214 is fixed on the protrusion 213, the length direction of the fixing groove 216 is also parallel to the width direction of the pusher belt 212. When the pusher belt 212 drives the protrusion 213 to rotate, the protrusion 213 will abut against the limiting plate 214, thereby causing the limiting plate 214 to rotate synchronously with it, thereby improving the reliability and timeliness of the capacitor core pushing position.

[0078] The push rod 217 is fixed to the side of the limiting plate 214 away from the insert block 215. The cam bearing follower 218 is fixed to the side of the push rod 217 away from the limiting plate 214. The cam bearing follower 218 is a commercially available CFUA6-16 model. The follower sleeve 220 is fitted onto the cam bearing follower 218 and is coaxially arranged with the capacitor core (specifically, the follower sleeve 220 is interference-fitted onto the roller of the cam bearing follower 218 to ensure that the follower sleeve 220 can rotate coaxially with the rotation of the capacitor core). The capacitor core is in an axial rotation state under the action of the turning roller. When the follower sleeve 220 moves forward against the capacitor core, the capacitor core will drive the follower sleeve 220 to rotate synchronously under the action of friction.

[0079] If the follower sleeve 220 is fixed or not coaxial with the capacitor core, when it abuts against the side of the axially rotating capacitor core, the capacitor core is likely to jump on the turning roller or fall off the turning roller.

[0080] The cover 219 is fixed on the push rod 217 and covers the nut side of the cam bearing follower 218 to prevent moisture or corrosive substances from entering, thereby playing a role in rust prevention and improving the service life of the cam bearing follower 218.

[0081] The limiting component is fixed to the inner side of the pusher frame 201 to support the limiting plate 214 during rotation. When the pusher component pushes the capacitor core forward, it prevents the pusher belt 212 from being deformed under gravity. Figure 10 , 11 As shown, the limiting assembly includes a fixing plate 221, a first slot 222, a first clearance groove 223, a second slot 224, a second clearance groove 225, a first limiting rod 226, a limiting groove 227, a second limiting rod 228, and a guide portion 229. The fixing plate 221 is fixed to the inner side of the pusher frame 201 by screws. The first slot 222 horizontally penetrates the fixing plate 221 and is located above the pusher belt 212. The first clearance groove 223 horizontally penetrates the fixing plate 221 and is connected to the first slot 222. When the pusher belt 212 drives the pusher assembly to move to push the capacitor core, it passes through the first clearance groove 223 to avoid the position of the limiting plate 214.

[0082] The upper and lower sides of the first slot 222 are formed with arc-shaped first insertion parts, and the arc center angle of the first insertion part is greater than 180°. Therefore, when the first limiting rod 226 is horizontally inserted into the first insertion parts on both sides of the first slot 222, the arc-shaped first insertion parts will lock the first limiting rod 226, preventing it from falling out of the first insertion part.

[0083] The limiting groove 227 is formed between the two first limiting rods 226, and the height of the limiting plate 214 is equal to the height of the limiting groove 227. By setting the two first limiting rods 226, when the pusher belt 212 drives the pusher assembly to move to push the capacitor core, the limiting plate 214 is placed in the limiting groove 227. The first limiting rod 226 below supports the limiting plate 214 upward, avoiding the gravity of the limiting assembly from acting directly on the pusher belt 212, which would deform the pusher belt 212 and affect the positional accuracy of the capacitor core.

[0084] Meanwhile, the first limiting rod 226 presses against the top of the limiting plate 214. During sandblasting, the sandblasting gun 407 sprays sandblasting glass beads towards one side of the capacitor core. The sandblasting glass beads easily hit the limiting component (the limiting component will swing away from the sandblasting gun 407 due to the force, and since the limiting component is fixed on the pusher belt 212, it will cause the pusher belt 212 to twist and deform, thus affecting the pushing of the capacitor core). Under the pressure of the first limiting rod 226, the limiting component is prevented from tilting away from the sandblasting gun, which would cause the pusher belt 212 to deform or push the capacitor core off.

[0085] The second slot 224 passes horizontally through the fixing plate 221 and is located below the pusher belt 212. The second clearance groove 225 passes through the fixing plate 221 and is connected to the second slot 224. After the pusher belt 212 drives the pusher assembly to move and push the capacitor core, when the pusher belt 212 is circulating, it will drive the pusher assembly to rotate to the bottom of the pusher belt 212. At this time, it will pass through the first clearance groove 223 to avoid the position of the limiting plate 214.

[0086] The bottom of the second slot 224 has an arc-shaped second insertion part, and the arc center angle of the second insertion part is greater than 180°. Therefore, when the second limiting rod 228 is horizontally inserted into the second insertion part at the bottom of the second slot 224, the arc-shaped second insertion part will lock the second limiting rod 228, preventing it from coming out of the second insertion part.

[0087] When the pusher belt 212 drives the pusher assembly to circulate, the pusher assembly rotates to the bottom of the pusher belt 212. Under the action of gravity, the pusher assembly will pull the pusher belt 212 downward, causing the pusher belt 212 to deform. Therefore, the limit plate 214 is supported by the second limit rod 228 (only one second limit rod 228 needs to be set during circulation, because the circulation position is below the pusher belt 212, and the sandblasting glass beads sprayed by the sandblasting gun 407 will not act on the pusher assembly at this point, so there is no need to set an extra limit rod).

[0088] The guide portion 229 is inclinedly disposed at both ends of the first limiting rod 226 and the second limiting rod 228, so that the limiting plate 214 can be rotated into the limiting groove 227 or onto the second limiting rod 228.

[0089] like Figure 14 The diagram shows a schematic of the pressing structure 3. The pressing structure 3 is positioned above the flipping structure 1. During sandblasting, the pressing structure 3 presses against the surface of the cylindrical capacitor core, preventing the capacitor core from falling off the flipping roller during flipping. The pressing structure 3 includes a second support frame, a second lifting mechanism, and a pressure rod 313. The second support frame is fixed to the top of the control box and primarily serves a supporting and fixing function. The second support frame includes a second lower support plate 301, second columns 303, and a second upper support plate 302. The second lower support plate 301 is fixed to the top of the control box by screws. There are at least two second columns 303, which are welded to the top of the second lower support plate 301 and spaced apart. The spacing of the second columns 303 provides clearance for the installation of the second lifting plate 306.

[0090] The second upper support plate 302 is fixed to the top of the second column 303 by welding. The second lower guide sleeve 304 is embedded in the second lower support plate 301. The second upper guide sleeve 305 is embedded in the second upper support plate 302. The second guide rod 309 passes through the second upper guide sleeve 305 and the second lower guide sleeve 304 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 301, which can satisfy the fixation of the second lower support plate 301, and at the same time, the second guide rod 309 can pass through the control box and extend into the interior of the control box).

[0091] The two ends of the second lead screw 307 are respectively mounted on the second lower support plate 301 and the second upper support plate 302 via bearings, and the second lead screw 307 is vertically arranged (i.e., the second lead screw 307 is parallel to the second guide rod 309). The second lifting plate 306 is fixed on the second guide rod 309 and cooperates with the second lead screw 307 (specifically, the second lifting plate 306 has a through hole that cooperates with the second guide rod 309, the second guide rod 309 passes through the through hole of the second lifting plate 306, and then the second lifting plate 306 and the second guide rod 309 are fixed together by welding; a lead screw nut is fitted on the second lead screw 307, and the lead screw nut is fixed on the second lifting plate 306 by screw fastening).

[0092] When the second lead screw 307 rotates, it will drive the second lifting plate 306 to move up and down. In turn, the second lifting plate 306 will drive the second guide rod 309 to move up and down, and finally drive the pressure rod 313 at the bottom of the second guide rod 309 to move up and down. The pressure rod 313 presses on the surface of the cylindrical capacitor core, preventing the cylindrical capacitor core from falling off when rotating and sandblasting.

[0093] The fourth motor 308 is fixed to the top of the second upper support plate 302 by screw fastening. The output shaft of the fourth motor 308 is connected to the second lead screw 307. The fourth motor 308 drives the second lead screw 307 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 309 and the pressure rod 313 are located on the inside of the control box).

[0094] The bottom of the second guide rod 309 is fixed with a second extension plate 310, which extends towards the side closer to the flipper 101 to ensure that the pressure rod 313 can press directly above the cylindrical capacitor core. The fixing post 311 is fixed to the side of the second extension plate 310 away from the second guide rod 309, and fixing blocks 312 are fixed to both ends of the fixing post 311. The two ends of the pressure rod 313 are rotatably mounted on the bottom of the fixing blocks 312 through bearings.

[0095] When the sandblasting gun 407 sandblasts the surface of the cylindrical capacitor core, the pressure rod 313 descends and presses against the surface of the cylindrical capacitor core. When the cylindrical capacitor core rotates, the pressure rod 313 rotates under the action of friction. Under the action of the pressure rod 313, the cylindrical capacitor core is prevented from falling off.

[0096] The sandblasting structure 4 is fixed to the bottom inside the control box and located on one side of the flipper 101. It performs sandblasting treatment on the circumferential surface of the capacitor core. The sandblasting structure 4 includes a sandblasting frame 401, a sandblasting bearing 402, a sandblasting guide post 403, a sandblasting screw 404, a sandblasting moving plate 405, a sandblasting motor 406, and a sandblasting gun 407. The sandblasting frame 401 is fixed to the bottom inside the control box by screws. The sandblasting bearing 402 is installed inside the sandblasting frame 401 and is set horizontally. The sandblasting guide post 403 passes through the sandblasting bearing 402, and the sandblasting gun 407 is fixed on the side of the sandblasting guide post 403 near the flipper 101. The sandblasting gun 407 sprays sandblasting glass beads onto the capacitor core.

[0097] The two ends of the sandblasting screw 404 are rotatably mounted in the sandblasting frame 401 through bearings. The sandblasting motor 406 is fixed on the sandblasting frame 401 by screws and is connected to the sandblasting screw 404. The sandblasting motor 406 drives the sandblasting screw 404 to rotate.

[0098] The sandblasting moving plate 405 is connected to the sandblasting guide post 403 and fixed on the sandblasting screw 404 (specifically, the sandblasting moving plate 405 has a through hole that matches the sandblasting guide post 403, the sandblasting guide post 403 passes through the through hole of the sandblasting moving plate 405, and then the sandblasting moving plate 405 and the sandblasting guide post 403 are fixed together by welding; a screw nut is provided on the sandblasting screw 404, and the screw nut is fixed on the sandblasting moving plate 405 by screw fastening).

[0099] The sandblasting motor 406 drives the sandblasting gun 407 to move closer to or further away from the capacitor core, thereby achieving different degrees of sandblasting effect and improving the versatility of the equipment.

[0100] The material-turning structure 1 is suspended inside the control box via a set of first support frames, and the material-turning frame 101 extends horizontally outward to the outside of the control box to facilitate the loading of cylindrical capacitor cores. The material-pressing structure 3 is suspended inside the control box via a second support frame and is located above the material-turning structure 1. The material-pushing structure 2 is fixed to the bottom inside the control box and located below the material-turning structure 1, and the sandblasting structure is fixed to the bottom inside the control box and located to one side of the material-turning structure 1.

[0101] During sandblasting, the capacitor core is placed on the turning roller, which drives the capacitor core to rotate axially. At the same time, the pusher belt 212 drives the pusher assembly to rotate, and the pusher assembly pushes the axially rotating capacitor core forward (during this process, the follower sleeve 220 is coaxially set with the capacitor core and moves forward against the capacitor core). When it moves to the sandblasting station, the pressure structure 3 descends and the pressure rod 313 presses against the outer circumference of the capacitor core, and the sandblasting gun 407 completes the sandblasting treatment of the capacitor core.

[0102] When replacing a small-diameter capacitor core, the sandblasting gun 407 can no longer spray the sandblasting glass beads along the diameter direction towards the capacitor core, which will affect the sandblasting effect; at the same time, the follower sleeve 220 and the capacitor core are not in a coaxial state. At this time, the first lifting mechanism drives the flipping frame 101 to rise, ensuring that capacitor cores of different diameters can also ensure that the core center is on a center line.
