Description

Technical Field

[0001] The present invention relates to the technical field of medical device processing, and in particular to a sandblasting system and method. Background Art

[0002] Most medical device products need to undergo high-temperature shaping treatment. In order to eliminate internal stress and improve overall performance, the surface of medical device products needs to be sandblasted to complete deoxidation and polishing of the product surface.

[0003] In the prior art, the sandblasting equipment includes a nozzle and a support member. The nozzle head can be connected to the sandblasting structure to perform sandblasting at a specified speed. The support member is inserted into the bracket along the axial direction of the bracket. One end of the support member is fixedly connected to a pulley. During the sandblasting operation, a driving motor drives the pulley to rotate through a belt, and the pulley then drives the bracket to rotate during the sandblasting process through the support member, thereby completing the sandblasting process.

[0004] However, during the sandblasting process, since the torque generated by the drive motor is transmitted to the bracket through the belt and the support, and the support is difficult to limit the bracket in the axial direction, the bracket is prone to axial movement when impacted during the sandblasting process, resulting in a deviation between the torque of the bracket and the torque of the drive motor. The rotation speed of the bracket is prone to unevenness, resulting in a poor sandblasting effect. Summary of the invention

[0005] The purpose of the present invention is to provide a sandblasting system and method, which solves the problem in the prior art that the support is prone to axial movement during the sandblasting process, resulting in uneven rotation speed, which leads to poor sandblasting effect.

[0006] To achieve this object, the present invention adopts the following technical solutions:

[0007] In a first aspect, the present application provides a sandblasting system, which comprises:

[0008] A sandblasting device, comprising a nozzle capable of reciprocating sliding and used for sandblasting;

[0009] A rotating shaft is arranged opposite to the spray head, and the bracket to be sandblasted is sleeved on the rotating shaft;

[0010] A plurality of groups of support components are distributed at intervals along the circumference of the rotating shaft, and the support components are passed through the mesh of the bracket and are fixedly connected to the rotating shaft;

[0011] A driving member is connected to the rotating shaft to drive the rotating shaft to drive the bracket to rotate.

[0012] Optionally, the support assembly comprises:

[0013] A first support rod is passed through the mesh of the bracket along a first direction and is clamped with the rotating shaft, and a side wall of the first support rod is tightly pressed against a wall of the mesh of the bracket;

[0014] The second support rod is passed through the mesh of the bracket along the second direction and is clamped with the rotating shaft, and the side wall of the second support rod is tightly pressed against the wall of the mesh of the bracket.

[0015] Optionally, an angle between the first direction and the second direction is β, 30°≤β≤150.

[0016] Optionally, the diameter of the stent is D, and the distance between the mesh through which the first support rod passes and the mesh through which the second support rod passes is L, where L=tan(β / 2)*D.

[0017] Optionally, the rotating shaft has a through hole corresponding to the supporting assembly, and the supporting assembly is inserted into the through hole.

[0018] Optionally, a connecting sleeve is provided at a position of the rotating shaft corresponding to the supporting assembly, and the connecting sleeve is elastic and has a plug-in hole for plugging the supporting assembly.

[0019] Optionally, the angle between the sandblasting direction of the nozzle and the axial direction of the rotating shaft is between 30° and 90°.

[0020] Optionally, the sandblasting device comprises:

[0021] An adjustment disk, the nozzle is arranged on the adjustment disk, and the adjustment disk is used to adjust the direction of the nozzle;

[0022] A driving assembly is connected to the adjusting disk to drive the adjusting disk to drive the nozzle to slide back and forth.

[0023] Optionally, a plurality of nozzles are arranged at intervals.

[0024] In the second aspect, the sandblasting method includes:

[0025] The bracket is sleeved on the rotating shaft, and a plurality of support components are inserted into the bracket at intervals so that the support components are clamped and fixed to the rotating shaft;

[0026] The driving member is started to operate, and the driving member drives the rotating shaft to drive the bracket to rotate through the supporting assembly;

[0027] The sandblasting device is started, and the spray head is controlled to slide back and forth relative to the support and perform sandblasting treatment on the support for multiple times during the sliding process.

[0028] Beneficial effects of the present invention:

[0029] First, during sandblasting, the bracket is sleeved on the rotating shaft, and multiple groups of support components are arranged at intervals on the bracket. The support components are fixed to the rotating shaft by clamping, so that a hard limit is formed between the bracket and the rotating shaft, thereby fixing the bracket on the rotating shaft and effectively limiting the axial movement of the bracket. When the driving member drives the rotating shaft to rotate, the rotating shaft can drive the bracket to rotate through the support component. During the rotation of the bracket, the nozzle of the sandblasting device can sandblast the bracket. During the sandblasting process, when the bracket is impacted, the support component is fixed to the rotating shaft and will not move, which can effectively limit the axial direction of the bracket and ensure that the bracket will not deviate along its axial direction. Therefore, when the sandblasting system sandblasts the bracket, it can ensure that the bracket does not have axial displacement on the rotating shaft, so that the bracket can rotate synchronously with the rotating shaft, ensure that the torque of the bracket matches the torque output by the driving member, and reduce the possibility of uneven rotation speed of the bracket. Then, the bracket can be evenly impacted by gravel, thereby effectively improving the effect of sandblasting.

[0030] Secondly, through the above steps, the bracket can be effectively limited during the sandblasting process to ensure that the bracket will not deviate in the axial direction, thereby ensuring that the rotation speed of the bracket remains stable, effectively improving the sandblasting effect of the bracket.

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0052] The embodiments of the present application disclose a sandblasting system and method.

[0053] Embodiment 1:

[0054] Reference Figure 1 The sandblasting system includes a sandblasting device 1, a rotating shaft 2, a driving member 3, and a plurality of supporting components 4. The sandblasting device 1 has a nozzle 11 that can reciprocate and slide and is used for sandblasting; the rotating shaft 2 is arranged opposite to the nozzle 11, and a bracket 5 to be sandblasted is sleeved on the rotating shaft 2; the plurality of supporting components 4 are distributed at intervals along the circumference of the rotating shaft 2, and the supporting components 4 are inserted into the mesh of the bracket 5 and are fixedly connected to the rotating shaft 2; the driving member 3 is connected to the rotating shaft 2 to drive the rotating shaft 2 to drive the bracket 5 to rotate.

[0055] Specifically, the sandblasting device 1 includes a suspension bracket 12, which is in the shape of an elongated strip. A driving assembly 121 is slidably connected to the middle of the suspension bracket 12. The driving assembly 121 can automatically move back and forth on the suspension bracket 12. The driving assembly 121 is fixedly connected to a suspension frame 13. A plurality of nozzles 11 can be distributed at intervals on the suspension frame 13. Each nozzle 11 is connected to the suspension frame 13 through an adjustment disk 131. The adjustment disk 131 can adjust the direction of the nozzle 11 so that the spray angle of the nozzle 11 can be flexibly adjusted. In this embodiment, the angle between the sandblasting direction of the nozzle 11 and the axial direction of the rotating shaft 2 is between 30° and 90°, so that while the sandblasting operation is carried out smoothly, the impact force on the structure such as the bracket 5 during the operation is ensured to be small.

[0056] A rotating shaft 2 is arranged below the nozzle 11, and one end of the rotating shaft 2 is connected to the output end of the driving member 3. The driving member 3 can be a motor, which is directly connected to one end of the rotating shaft 2 through a coupling, or can be connected to one end of the rotating shaft 2 through a belt drive or a chain drive structure, as long as the rotating shaft 2 can be smoothly driven to rotate. The bracket 5 is in a grid-like long cylindrical shape, which is sleeved on the rotating shaft 2. A plurality of groups of supporting components 4 are distributed at intervals in the axial direction of the bracket 5. The supporting components 4 pass through the bracket 5 and form a clamping fixation with the rotating shaft 2, wherein the supporting components 4 and the bracket 5 can be pressed against each other to form a lock, and the supporting components 4 and the rotating shaft 2 can be plugged in to achieve an interference fit type clamping fixation or a taper fit type clamping fixation, so that a hard limit is formed between the bracket 5 and the rotating shaft 2, for example, the aperture of the through hole of the rotating shaft 2 is slightly smaller than the outer diameter of the inserted part of the supporting component 4 to form an interference fit type clamping fixation, and the taper fit type clamping fixation can be achieved by setting the through hole of the rotating shaft 2 as a tapered hole or setting the inserted part of the supporting component 4 to be tapered.

[0057] During sandblasting, the bracket 5 is sleeved on the rotating shaft 2, and multiple groups of support components 4 are arranged on the bracket 5 at intervals. The support components 4 are fixed to the rotating shaft 2 by clamping, so that a hard limit is formed between the bracket 5 and the rotating shaft 2, thereby fixing the bracket 5 on the rotating shaft 2 and effectively limiting the axial movement of the bracket 5. When the driving member 3 drives the rotating shaft 2 to rotate, the rotating shaft 2 can drive the bracket 5 to rotate through the support components 4. During the rotation of the bracket 5, the nozzle 11 of the sandblasting device 1 can sandblast the bracket 5. During the sandblasting process, when the bracket 5 is impacted, the support components 4 are fixed to the rotating shaft 2 by clamping and will not move, so as to effectively limit the axial direction of the bracket 5 and ensure that the bracket 5 will not deviate along its axial direction. Therefore, when the sandblasting system is sandblasting the bracket 5, it can ensure that the bracket 5 does not undergo axial displacement on the rotating shaft 2, so that the bracket 5 can rotate synchronously with the rotating shaft 2, ensuring that the torque of the bracket 5 matches the torque output by the driving member 3, and reducing the possibility of uneven rotation speed of the bracket 5. The bracket 5 can then be evenly impacted by the sand, thereby effectively improving the effect of the sandblasting.

[0058] Reference Figures 2 to 5 Optionally, the support assembly 4 includes a first support rod 41 and a second support rod 42. The first support rod 41 is passed through the mesh of the bracket 5 along the first direction and is clamped with the rotating shaft 2, and the side wall of the first support rod 41 is tightly pressed against the mesh wall of the bracket 5; the second support rod 42 is passed through the mesh of the bracket 5 along the second direction and is clamped with the rotating shaft 2, and the side wall of the second support rod 42 is tightly pressed against the mesh wall of the bracket 5.

[0059] Specifically, the mesh of the bracket 5 includes two first meshes 51 and two second meshes 52. The two first meshes 51 correspond to each other when the bracket 5 is in a cylindrical shape, so that the first support rod 41 can pass through. The side wall of the first support rod 41 is tightly pressed against the hole wall of the first mesh 51 to lock the first support rod 41. A through hole 21 is provided on the rotating shaft 2. The first support rod 41 passes through the through hole 21 and passes out from another first mesh 51 to achieve the clamping fixation of the first support rod 41 and the rotating shaft 2. The second support rod 42 is provided in a different direction from the first support rod 41, and the present application will not repeat it here. The first support rod 41 and the second support rod 42 are spaced a certain distance apart along the circumference of the bracket 5.

[0060] By setting the first support rod 41 and the second support rod 42, the bracket 5 can be limited in at least two directions, thereby ensuring that the connection strength between the bracket 5 and the rotating shaft 2 is good. Then, during the rotation process, the rotating shaft 2 can drive the first support rod 41 and the second support rod 42 to rotate synchronously, and the first support rod 41 and the second support rod 42 can drive the bracket 5 to rotate synchronously.

[0061] Reference Figures 6 to 9Optionally, the angle between the first direction and the second direction is β, 30°≤β≤150°, the diameter of the bracket 5 is D, and the spacing between the mesh through which the first support rod 41 passes and the mesh through which the second support rod 42 passes is L, L=tan(β / 2)*D.

[0062] Specifically, the diameter of the stent 5 when fully expanded is D. When the diameter D changes, the relative positions of the first mesh 51 and the second mesh 52 will also change, and accordingly, the angles formed by the first support rod 41 and the second support rod 42 after being inserted will also be different. By limiting the angle β to a range of 30° to 150°, the first support rod 41 and the second support rod 42 can cross, and stents 5 of various sizes can be effectively limited and fixed. When the diameter D of the stent 5 changes, according to L=tan(β / 2)*D, the spacing L between the first support rod 41 and the second support rod 42 along the axial direction of the stent 5 is adjusted accordingly, so that the limiting position between the support assembly 4 and the stent 5 can be appropriately adjusted according to the size of the stent 5, ensuring that the stent 5 is effectively limited. The number of specific support assemblies 4 can also be adjusted according to the size of the stent 5. In this embodiment, only one group of support assemblies 4 is set at each end of the stent 5.

[0063] Reference Figures 10 to 12 Optionally, when the stent 5 is in the rolled-up state and the diameter of the stent 5 is D when it is fully expanded, the arc length between the mesh through which the first support rod 41 passes and the mesh through which the second support rod 42 passes can be set to H, H = (β / 180)*πD. At this time, H is proportional to the diameter D, that is, when the diameter of the stent 5 is larger, the larger H is, and the arc length of the first support rod 41 and the second support rod 42 along the circumferential direction of the stent 5 is also larger, so that the arc length of the first support rod 41 and the second support rod 42 can be appropriately adjusted according to the size of the stent 5, thereby ensuring that the stent 5 can maintain a high connection strength with the rotating shaft 2. The calculation of the spacing L or the arc length H based on the diameter D of the stent 5 has the same effect, and one of them can be selected for calculation according to actual conditions during design.

[0064] The sandblasting method includes:

[0065] Reference Fig.13 Step S1: sleeve the bracket 5 on the rotating shaft 2, insert a plurality of support components 4 on the bracket 5 at intervals, and make the support components 4 be clamped and fixed to the rotating shaft 2;

[0066] Step S2: starting the driving member 3 to operate, the driving member 3 drives the rotating shaft 2 to drive the bracket 5 to rotate through the supporting assembly 4;

[0067] Step S3: Start the sandblasting device 1, control the spray head 11 to slide back and forth relative to the support 5, and perform sandblasting on the support 5 for multiple times during the sliding process.

[0068] Specifically, multiple brackets 5 can be set on the rotating shaft 2 at the same time, and each bracket 5 can be correspondingly provided with multiple support assemblies 4, and the support assembly 4 and the rotating shaft 2 can form an interference fit type clamping fixation, or a taper fit type clamping fixation, so that each bracket 5 is fixed on the rotating shaft 2. The driving member 3 can drive the rotating shaft 2 and the bracket 5 to rotate at a speed w, and the range of w can be 100rpm-600rpm. Before starting the sandblasting, the spray direction of the nozzle 11 located on the right side of the bracket 5 intersects with the rotating shaft 2 at 2cm to 5cm in front of the head end of the bracket 5. After starting the sandblasting, the nozzle 11 moves at a uniform speed v, and v can be between 0.05m / min and 0.3m / min. When the spray direction of the nozzle 11 located on the left side of the bracket 5 intersects with the rotating shaft 2 at 2cm to 5cm at the tail end of the bracket 5, the nozzle 11 starts to move in the opposite direction and returns to the initial position, and the single sandblasting ends. Generally, the above-mentioned sandblasting process is performed 2 to 6 times.

[0069] Through the above steps S1 to S3, the bracket 5 can be effectively limited during the sandblasting process to ensure that the bracket 5 will not deviate in the axial direction, thereby ensuring that the rotation speed of the bracket 5 remains stable, and effectively improving the sandblasting effect of the bracket 5.

[0070] Embodiment 2

[0071] On the basis of the first embodiment, the difference between this embodiment and the first embodiment lies in the different connection modes between the rotating shaft 2 and the supporting assembly 4 .

[0072] Reference Figure 14 to Figure 15 Optionally, a connecting sleeve 6 is provided at a position of the rotating shaft 2 corresponding to the supporting assembly 4 , and the connecting sleeve 6 is elastic and has a plug-in hole for the supporting assembly 4 to be plugged in.

[0073] Specifically, a connecting sleeve 6 is fixedly provided on the rotating shaft 2. The fixing method can be a non-detachable method such as welding or bonding, or a detachable method such as screw connection, clamping or bolt connection. Taking the bolt connection as an example, a through threaded hole is opened on the connecting sleeve 6, and the bolt is screwed into the threaded hole, and the bolt can extend into the connecting sleeve 6 to form a tight contact with the rotating shaft 2, thereby realizing the fixed connection between the connecting sleeve 6 and the rotating shaft 2.

[0074] The connecting sleeve 6 is made of a material with a certain elasticity such as hard rubber, and a plug-in hole is opened on the outer wall of the connecting sleeve 6. The first support rod 41 can be plugged into the plug-in hole and pass through the through hole 21 on the rotating shaft 2 and pass out from the plug-in hole on the other side, and then pass through the first mesh 51 and pass out of the bracket 5. Similarly, the second support rod 42 is also set through the bracket 5. In another embodiment, a connecting sleeve 6 is corresponding to the first support rod 41, and another connecting sleeve 6 is corresponding to the second support rod 42. It can be adjusted according to the actual spacing between the first support rod 41 and the second support rod 42, and the present application does not limit this.

[0075] By providing the elastic connecting sleeve 6, the plug-in hole can be deformed to a certain extent when the supporting assembly 4 is plugged into the plug-in hole, so as to facilitate the insertion of the first supporting rod 41 and the second supporting rod 42 of the supporting assembly 4 at different angles. It should be understood that after providing the connecting sleeve 6, it is not necessary to make a separate hole on the rotating shaft 2. In this case, the first supporting rod 41 and the second supporting rod 42 no longer pass through the rotating shaft 2, and plug-in holes are respectively provided on the opposite sides of the connecting sleeve 6. The first supporting rod 41 is divided into two sections, one of which passes through a first mesh 51 and is inserted into the plug-in hole, and the other end is inserted from another first mesh 51 and plugged into the corresponding plug-in hole. The second supporting rod 42 is provided in a similar manner, so there is no need to make a hole on the rotating shaft 2 to ensure that the strength of the rotating shaft 2 meets the requirements.

[0076] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here.
