[0054] Referring to Figures 1 to 8 As shown in the figure, a sand blasting device for heat dissipation copper bar processing, in actual application, for heat dissipation copper bar surface sand blasting pretreatment operation, it includes box body 1, set in the sand blasting device 2 and clamping mechanism 3 in the box body 1 and clamping mechanism 3 connected turnover mechanism 4.

[0055] Specifically, the box 1 is internally provided with a recess, which is a collecting groove 11, and the fine sand and impurities on the surface of the heat dissipation copper bar are collected through the collecting groove 11. In this embodiment, the sand blasting device 2 is fixedly arranged in the box 1 and located above the collecting groove 11. The sand blasting device 2 is composed of a sand blasting tank, a compressed air system and other components. By using compressed air as power, the sand blasting device 2 can spray abrasive materials at high speed to the surface of the workpiece. When the abrasive materials hit the surface of the workpiece, cutting and impact effects are generated on the surface of the workpiece to remove rust, oxide layer, oil stains and old paint layer on the surface of the heat dissipation copper bar. The clamping mechanism 3 is arranged in the box 1 and located below the sand blasting device 2. The heat dissipation copper bar is clamped and fixed by the clamping mechanism 3 during the sand blasting operation. The turnover mechanism 4 is fixedly arranged in the collecting groove 11 of the box 1 and parallel to the length direction of the collecting groove 11. The clamping mechanism 3 is connected with the turnover mechanism 4. During the sand blasting operation of the heat dissipation copper bar, the clamping mechanism 3 is turned over by the turnover mechanism 4, so that the turnover of the heat dissipation copper bar is realized. In this embodiment, after the heat dissipation copper bar is clamped and fixed by the clamping mechanism 3, the sand blasting device 2 is turned over by the turnover mechanism 4 during the sand blasting operation, so that the turnover of the heat dissipation copper bar is realized. That is, the defect that the production efficiency is reduced due to the manual multiple turnover of the heat dissipation copper bar during the sand blasting operation is effectively solved, and the technical effect that the heat dissipation copper bar is uniformly sand blasted on multiple surfaces is realized.

[0056] Please refer to Figures 3 to 7As shown, the turnover mechanism 4 comprises a main rotating assembly 41 fixedly arranged in the collecting groove 11 and located at one side of the slot opening of the collecting groove 11. Specifically, the main rotating assembly comprises two slide rails 411, a first sliding block 412 connected with the two slide rails 411, a rotating roller 413 connected with the first sliding block 412, a gear 414 arranged on the rotating roller 413, a rack 415 connected with the gear 414, and a transmission screw rod 416 connected with the first sliding block 412. The two slide rails 411 are arranged in the collecting groove 11, both ends of the two slide rails 411 are fixedly connected with the collecting groove 11, and the two slide rails are arranged in parallel, i.e., the two slide rails are located on the same plane perpendicular to the bottom end of the collecting groove 11. In some preferred embodiments, the slide rail 411 is a linear guide rail. Compared with a single guide rail, the structure is more stable by using two guide rails. The first sliding block 412 is located between the two slide rails 411 and is slidably connected with the two slide rails 411, so that the first sliding block 412 moves linearly along the rail under the guidance of the two slide rails 411. One end of the rotating roller 413 is rotatably connected with the first sliding block 412 through a rotating shaft or the like, and the clamping mechanism 3 is fixedly connected with the other end of the rotating roller 413. When the first sliding block 412 moves, the rotating roller 413 can move simultaneously. In order to make the rotating roller 413 rotate while moving, the gear 414 is fixedly sleeved on the rotating roller 413, both ends of the rack 415 are fixedly connected with the collecting groove 11 and are adapted with the gear 414, i.e., the gear 414 is connected with the rack 415 in meshing. By moving the first sliding block 412, the gear 414 also moves on the rack 415 while the rotating roller 413 moves. Since the gear 414 is connected with the rack 415 in meshing, the gear 414 rotates when it moves, so that the rotating roller rotates when it moves, thereby driving the clamping mechanism 3 to rotate, so that the heat dissipation copper bar fixedly clamped on the clamping mechanism 3 is turned over. In order to make the first sliding block 412 move, the transmission screw rod 416 is arranged between the two slide rails 411, both ends of the transmission screw rod 416 are rotatably connected with the collecting groove 11, and the transmission screw rod 416 passes through the first sliding block 412 and is threadedly connected therewith, i.e., by rotating the transmission screw rod 416, the threaded connection between the transmission screw rod 416 and the first sliding block 412 is meshed, so that the rotary motion of the transmission screw rod 416 is converted into the linear motion of the first sliding block 412, thereby enabling the first sliding block 412 to move along the slide rail 411. Further, in order to control the rotation of the transmission screw rod 416, the driver 417 is fixedly arranged on one side of the box body 1 and is adapted with the transmission screw rod 416, i.e., the driver 417 can adopt a motor, an electric motor or the like driving structure, and the output end thereof is fixedly connected with the transmission screw rod 416, so that the transmission screw rod 416 rotates through the driver 417.

[0057] In some preferred embodiments, the transmission screw rod 416 is a reciprocating screw rod, and the first sliding block 412 is internally provided with threads matched with the reciprocating screw rod. For example, the main body of the reciprocating screw rod is symmetrically provided with left and right screw threads, i.e., half of the threads are left-handed and the other half are right-handed. The left-handed thread segment cooperates with a part of the first sliding block 412, and the right-handed thread segment cooperates with another part of the first sliding block 412. When the screw rod rotates in one direction, the first sliding block 412 changes its moving direction after sliding to one end of the reciprocating screw rod, and moves in the opposite direction, so that the first sliding block 412 can reciprocate along the path of the sliding rail 411 under the action of the reciprocating screw rod, thereby causing the heat dissipation copper bar fixedly clamped on the clamping mechanism 3 to reciprocate and flip.

[0058] The flipping mechanism 4 further comprises a secondary rotating assembly 42 fixedly arranged in the collection groove 11 and located at the other side of the opening of the collection groove 11. The secondary rotating assembly 42 is matched with the primary rotating assembly 41, i.e., the center points of the secondary rotating assembly 42 and the primary rotating assembly 41 are located on the same horizontal plane, so as to cooperate with the primary rotating assembly 41 to keep the rotating axis of the clamping mechanism 3 consistent and horizontal. Specifically, the secondary rotating assembly 42 comprises a fixed rod 421, a second sliding block 422 connected with the fixed rod 421, and an auxiliary rod 423 connected with the second sliding block 422. The fixed rod 421 is arranged in the collection groove 11 and located at the other side of the opening away from the primary rotating assembly 41. The second sliding block 422 is arranged on the fixed rod 421, and the second sliding block 422 is movably connected with the fixed rod 421 by means of a ball bearing or the like. In addition, the fixed rod 421 is matched with the transmission screw rod 416, i.e., the axis of the fixed rod 421 and the axis of the transmission screw rod 416 are located on the same horizontal plane, so that the moving paths of the first sliding block 412 and the second sliding block 422 are kept horizontal. The flipping mechanism 4 is movably connected with the end of the second sliding block 422 close to the primary rotating assembly 41. In order to further limit the second sliding block 422, the auxiliary rod 423 penetrates through the second sliding block 422 and is movably connected with the second sliding block 422. The two ends of the auxiliary rod 423 are fixedly connected with the collection groove 11, and are used for auxiliary positioning of the second sliding block 422. The second sliding block 422 is limited by the fixed rod 421 and is auxiliary positioned by the auxiliary rod 423, so as to prevent the second sliding block 422 from rotating around the fixed rod 421 during sliding.

[0059] In the embodiment, the clamping mechanism 3 comprises two clamping assemblies, one of which is connected with the rotating roller 413, and the other of which is connected with the second sliding block 422. For the convenience of description, one of the clamping assemblies is described herein, which comprises a bracket 31 and two clamping heads 32 connected with the bracket 31. Specifically, the bracket 31 is in the form of a long strip-shaped plate structure, which provides a relatively stable planar support when clamping the heat dissipation copper bar. The bracket 31 arranged at the center of the rotating roller 413 is fixedly connected with the rotating roller 413, and the bracket 31 arranged at the center of the second sliding block 422 is movably connected with the second sliding block 422. The two clamping heads 32 are fixedly connected with the bracket 31, and the clamping heads 32 are used for clamping the heat dissipation copper bar. The two clamping heads 32 are respectively located at the two ends of the bracket 31, so as to disperse the clamping pressure of the clamping heads 32 on the heat dissipation copper bar and clamp the heat dissipation copper bar more stably.

[0060] As shown in Figure 6 and Figure 8 In the embodiment, in order to reduce the shock during the turning of the heat dissipation copper bar, the clamping head 32 is fixedly connected with the bracket 31 through an elastic expansion piece 33. Preferably, the elastic expansion piece 33 comprises an expansion rod 331 and a spring 332. One end of the expansion rod 331 is fixedly connected with the bracket 31, and the other end is fixedly connected with the clamping head 32, so as to support the clamping head 32 and disperse the inertial force during the turning of the heat dissipation copper bar. The spring 332 is wound outside the expansion rod 331. During the turning of the heat dissipation copper bar, the spring 332 can effectively reduce the impact by virtue of its elasticity, and make the clamping head 32 always slightly move in the path of the expansion rod 331, thereby improving the clamping effect of the clamping head 32.

[0061] As shown in Figures 1 to 2As shown, in order to improve the sand blasting coverage area, a plurality of spray assemblies are arranged on the sand blaster 2 in the embodiment. The plurality of spray assemblies are arranged at the bottom end of the sand blaster 2 and are uniformly distributed on the upper end of the collection groove 11 and are in communication with the sand outlet pipe of the sand blaster 2, so that the fine sand in the sand blaster 2 is sprayed out through the spray assemblies. Specifically, in order to facilitate the description of the spray assemblies, one spray assembly is described herein. The spray assembly comprises a flow distribution box 21, a nozzle 22 connected to the flow distribution box 21, and an inductive switch 23. Specifically, the flow distribution box 21 is located at the bottom end of the sand blaster 2 and is in communication with the sand outlet pipe of the sand blaster 2. The fine sand in the sand blaster 2 flows into each flow distribution box 21 for distribution. The nozzle 22 is arranged at the bottom end of the flow distribution box 21 and is in communication with the flow distribution box 21 for spraying the fine sand in the flow distribution box 21. In some preferred embodiments, in order to further improve the sand blasting coverage area, a plurality of nozzles 22 are arranged to facilitate multi-position sand blasting of the heat dissipation copper bar and improve the uniformity of the sand blasting effect. Because the existing sand blasting machine technology is continuously operated for a long time, the nozzle 22 will deform due to excessive heating, the material hardness will decrease, and the service life will be reduced. Therefore, in the embodiment, the opening and closing of the flow distribution box 21 is controlled to control the working time of the nozzle 22 for sand blasting to prevent the nozzle 22 from being continuously operated for too long. Specifically, the inductive switch 23 is fixedly arranged on the collection groove 11 and is in electrical connection with the flow distribution box 21. The inductive switch 23 is adapted to the rotating roller 413. For example, the inductive switch 23 is an inductive inductive switch 23 which is composed of a high-frequency oscillation circuit, a detection circuit, and an output circuit. The position of the rotating roller is sensed, the signal is transmitted to the controller, and the opening and closing of the flow distribution box 21 is controlled by the controller, so that when the heat dissipation copper bar is located at the spraying position of one spray assembly, only the nozzle 22 corresponding to the position is used for sand blasting operation, and the flow distribution boxes 21 at other positions are kept closed, thereby controlling the sand blasting operation time of the nozzle 22 and avoiding excessive heating of the nozzle 22 due to continuous operation.

[0062] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
