Description

Technical Field

[0001] The invention relates to the technical field of particle detection equipment, and in particular to a particle detection equipment and process after injection molding of a loudspeaker bracket. Background Art

[0002] The injection molding process of the speaker stand usually includes the following steps: Design the mold: According to the shape and size of the speaker stand, design a suitable injection mold to ensure that it can be accurately molded. Prepare materials: Select suitable plastic materials (such as ABS, PC, PP, etc.) according to the needs and characteristics of the product. Heating and melting: Put the plastic particles into the injection molding machine and heat them to their molten state for subsequent injection into the mold. Injection into the mold: Inject the molten plastic into the mold cavity through the injection system to ensure uniform filling. Cooling and solidification: Wait for a period of time in the mold to allow the plastic to cool and solidify to form a fixed shape. Open the mold and take out the part: After the injection molding is completed, open the mold and take out the molded speaker stand. Post-processing: Deburr, grind, clean and other post-processing are performed on the removed bracket to meet the final quality requirements. Quality inspection: Perform quality inspection on the appearance, size and performance of the finished product to ensure that it meets the design standards.

[0014] A process for particle detection equipment after injection molding of a speaker bracket includes the following steps:

[0015] S1: Fix the bracket. First, place the bracket on the load-bearing arc plate. Under the extrusion action of the extrusion column, the extrusion column drives the extrusion sheet 1 to squeeze the extrusion sheet 2 at one end of the extrusion spring, and the extrusion sheet 2 squeezes one end of the bracket, thereby achieving the purpose of fixing the bracket;

[0016] S2: Cleaning the surface of the bracket. The gear and the rack are meshed. The rotation of the gear drives the bracket at one end of the extrusion column to rotate, and the surface of the bracket and the bristles at the bottom of the cleaning plate produce friction;

[0017] S3: Auxiliary detection, the limit block on the extrusion column drives the push plate to move, the push plate drives the sliding column at one end of the linkage rod to slide downward, and the sliding column drives the load-bearing arc plate to slide downward, so that the load-bearing arc plate is separated from the bracket, avoiding friction between the bracket and the load-bearing arc plate during rotation, thereby avoiding wear on the bracket surface;

[0018] S4: Detection and rejection. The detection camera is used to detect whether there is a problem with the bracket. When the bracket needs to be rejected, the detection camera starts the electric telescopic rod, which drives the sliding extrusion block to disengage from the extrusion column. At this time, the rotating round block slides upward and contacts the friction plate. The friction plate drives the rotating round block to rotate. The rotation of the rotating round block drives the rotation of the load-bearing arc plate. The rotation of the load-bearing arc plate dumps the bracket into the waste bin directly below.

[0019] The present invention has the following beneficial effects:

[0020] (1) When the detection device of the present invention is used, the driving motor is first started, and the speaker bracket to be detected is placed in the interior of the load-bearing arc plate in sequence. The output end of the driving motor drives the conveying turntable on the output shaft to rotate, and the rotation of the conveying turntable drives a plurality of bearing bases on the conveying belt to rotate. The bearing bases rotate and move toward one end close to the storage box. When the extrusion column is close to one end of the conveying belt and is squeezed with the special-shaped extrusion block, the extrusion column slides inward along the conveying belt, and the extrusion column drives the extrusion sheet 1 to move toward one end of the bracket. The extrusion sheet 1 drives the extrusion sheet 2 on the extrusion spring to be squeezed with one end of the bracket. Under the extrusion action of the extrusion sheet 2, the bracket is fixed between the two extrusion sheets 2. This arrangement is conducive to the stable movement of the bracket inside the device, avoids the bracket from sliding during the detection process, and improves the detection stability of the device.

[0021] (2) The present invention sets a rotating cleaning structure. When the gear and the rack are meshed, the gear rotates. The rotation of the gear drives the extrusion column to rotate. The rotation of the extrusion column drives the extrusion sheet 1 to rotate. The rotation of the extrusion sheet 1 drives the extrusion sheet 2 at one end of the extrusion spring to rotate. The rotation of the extrusion sheet 2 drives the bracket to rotate. The rotation of the bracket causes the surface of the bracket to rub against a plurality of bristles at the bottom of the cleaning plate. This arrangement is conducive to cleaning dust on the surface of the bracket, avoiding mistaken identification of dust as particles during particle detection, thereby improving the detection accuracy of the device. On the other hand, the rotation of the bracket driven by the gear is conducive to the bristles at the bottom of the cleaning plate to comprehensively clean the surface of the bracket, avoiding omissions in cleaning the surface of the bracket.

[0022] (3) In the present invention, an auxiliary detection mechanism is set up, so that the extrusion column and the special-shaped extrusion block squeeze each other, the extrusion column drives the limit block to move inward, the limit block drives the push plate to move along the extrusion column to one end close to the bracket, the push plate drives the sliding column at one end of the linkage rod to slide downward along the bearing base, at this time, the sliding column drives the sliding plate to squeeze the reset spring downward, the sliding plate moves downward and drives the rotating round block at one end of the connecting column to move downward, the rotating round block moves downward and drives the bearing arc plate to move downward, the bearing arc plate moves downward and disengages from the bottom of the bracket, such a setting is conducive to making the rotating bracket disengage from the bearing arc plate, avoiding friction between the bracket rotation and the bearing arc plate, thereby avoiding friction damage to the bracket surface and improving the production quality of the bracket.

[0023] (4) The present invention sets a detection and rejection mechanism. When the bracket moves to the bottom of the detection camera, the detection camera uses computer detection to determine whether there are injection molding particles left on the surface of the bracket. When it is detected that the bracket has quality defects, the program controls the electric telescopic rod to shrink. The shrinkage of the electric telescopic rod drives the sliding extrusion block to move to the outside of the equipment housing. At this time, the sliding extrusion block and the extrusion column are separated and squeezed each other. At this time, the extrusion column slides outward to drive the extrusion sheet 2 on the extrusion spring to separate from the two ends of the bracket. The bracket falls back to the inside of the load-bearing arc plate. Under the rebound action of the reset spring, the sliding plate drives the load-bearing arc plate on the rotating circular block to move upward. At this time, the rotating circular block contacts the friction plate at one end of the friction fixing rod. Under the friction action of the friction plate, the rotating circular block drives the load-bearing arc plate to rotate. At this time, the rotating circular block rotates around the connecting column. The load-bearing arc plate rotates to dump the bracket into the waste bin directly below, thereby realizing the rejection of defective products.

[0024] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

The bearing base 201 rotates and moves toward one end close to the storage box 15. When the extrusion column 207 is close to one end of the conveying belt 14 and is squeezed by the special-shaped extrusion block 211, the extrusion column 207 slides inward along the conveying belt 14. The extrusion column 207 drives the extrusion piece 1 208 to move toward one end of the bracket. The extrusion piece 1 208 drives the extrusion piece 210 on the extrusion spring 209 to be squeezed with one end of the bracket. Under the extrusion action of the extrusion piece 210, the bracket is fixed between the two extrusion pieces 210. This arrangement is conducive to the stable movement of the bracket inside the device, avoids the bracket from sliding during the detection process, and improves the detection stability of the device.

[0041] The interior of the device housing 1 is provided with a rotating cleaning structure 3, which includes a gear 301 fixedly connected to the end of the extrusion column 207 near the conveyor belt 14, a rack 302 fixedly connected to the side inner wall of the device housing 1 of the driving motor 11, a connecting frame 303 fixedly connected to the side inner wall of the device housing 1, a cleaning plate 304 fixedly connected to the end of the connecting frame 303 away from the inner wall of the device housing 1, and a plurality of bristles fixedly connected to the bottom of the cleaning plate 304. The function of this component is to rotate the gear 301 when it is meshed with the rack 302 by setting the rotating cleaning structure 3, and the gear 301 rotates. The extrusion column 207 is driven to rotate, and the rotation of the extrusion column 207 drives the extrusion piece 1 208 to rotate. The rotation of the extrusion piece 1 208 drives the extrusion piece 2 210 at one end of the extrusion spring 209 to rotate. The rotation of the extrusion piece 210 drives the bracket to rotate.

On the other hand, the gear 301 drives the bracket to rotate, which is conducive to the bristles at the bottom of the cleaning plate 304 to comprehensively clean the surface of the bracket, avoiding omissions in cleaning the surface of the bracket.

[0042] Embodiment 2 is different from Embodiment 1 in that: Figure 1-Figure 9 As shown, an auxiliary detection mechanism 4 is provided on the extrusion column 207, and the auxiliary detection mechanism 4 includes a limit block 401 fixedly connected to one end of the extrusion column 207 close to the extrusion sheet 208, and a push plate 402 is slidably connected to the extrusion column 207, and the limit block 401 contacts the push plate 402, and both ends of the push plate 402 are rotatably connected to the linkage rod 403, and a reset spring 404 is sleeved on the sliding column 202. The function of this component is to squeeze the extrusion column 207 and the special-shaped extrusion block 211 against each other by setting the auxiliary detection mechanism 4, and the extrusion column 207 drives the limit block 401 to move inward, and the limit block 401 drives the push plate 402 along the extrusion column 207 to move close to the support One end of the frame moves, and the push plate 402 drives the sliding column 202 at one end of the linkage rod 403 to slide downward along the bearing base 201. At this time, the sliding column 202 drives the sliding plate 203 to squeeze the reset spring 404 downward, and the sliding plate 203 moves downward to drive the rotating round block 205 at one end of the connecting column 204 to move downward, and the rotating round block 205 moves downward to drive the bearing arc plate 206 to move downward, and the bearing arc plate 206 moves downward and disengages from the bottom of the bracket. This arrangement is conducive to making the rotating bracket disengage from the bearing arc plate 206, avoiding friction between the bracket rotation and the bearing arc plate 206, thereby avoiding friction damage to the bracket surface and improving the production quality of the bracket.

[0043] A detection and rejection mechanism 5 is arranged directly above the device housing 1, and the detection and rejection mechanism 5 includes a detection rod 501 fixedly connected to the inner wall of the side of the device housing 1, a plurality of detection cameras 502 are fixedly connected to the middle of the detection rod 501, and a connecting plate 503 is fixedly connected to the side wall of the device housing 1.

[0044] The detection and rejection mechanism 5 also includes an electric telescopic rod 504 fixedly connected to the end of the connecting plate 503 away from the equipment housing 1, the detection camera 502 is electrically connected to the electric telescopic rod 504, and the end of the electric telescopic rod 504 away from the connecting plate 503 is fixedly connected with a sliding extrusion block 505, the sliding extrusion block 505 is slidably connected to the special-shaped extrusion block 211, and the sliding extrusion block 505 and the special-shaped extrusion block 211 are located on the same horizontal line.

The function of this component is to set up the detection and rejection mechanism 5. When the bracket moves to the bottom of the detection camera 502, the detection camera 502 uses computer detection to determine whether there are injection molding particles left on the surface of the bracket. When it is detected that the bracket has quality defects, the program controls the electric telescopic rod 504 to shrink. , the electric telescopic rod 504 contracts and drives the sliding extrusion block 505 to move outside the equipment housing 1. At this time, the sliding extrusion block 505 and the extrusion column 207 are separated from each other and squeezed. At this time, the extrusion column 207 slides outward to drive the extrusion piece 210 on the extrusion spring 209 to separate from the two ends of the bracket, and the bracket falls back to the inside of the load-bearing arc plate 206. Under the rebound action of the reset spring 404, the sliding plate 203 drives the load-bearing arc plate 206 on the rotating circular block 205 to move upward. At this time, the rotating circular block 205 contacts the friction plate 509 at one end of the friction fixing rod 508. Under the friction action of the friction plate 509, the rotating circular block 205 drives the load-bearing arc plate 206 to rotate. At this time, the rotating circular block 205 rotates around the connecting column 204, and the load-bearing arc plate 206 rotates to dump the bracket into the waste box 510 directly below, thereby realizing the removal of defective products.

[0046] A process for particle detection equipment after injection molding of a speaker bracket includes the following steps:

[0047] S1: Fix the bracket. First, place the bracket on the load-bearing arc plate 206. Under the extrusion action of the extrusion column 207, the extrusion column 207 drives the extrusion piece 1 208 to squeeze the extrusion piece 2 210 at one end of the extrusion spring 209. The extrusion piece 210 squeezes one end of the bracket, thereby achieving the purpose of fixing the bracket;

[0048] S2: cleaning the surface of the bracket, the gear 301 is meshed with the rack 302, the gear 301 rotates to drive the bracket at one end of the extrusion column 207 to rotate, and the surface of the bracket and the bristles at the bottom of the cleaning plate 304 generate friction;

[0049] S3: Auxiliary detection, the limit block 401 on the extrusion column 207 drives the push plate 402 to move, the push plate 402 drives the sliding column 202 at one end of the linkage rod 403 to slide downward, and the sliding column 202 drives the bearing arc plate 206 to slide downward, so that the bearing arc plate 206 is separated from the bracket, avoiding friction between the bracket and the bearing arc plate 206 during rotation, thereby avoiding wear on the bracket surface;

[0050] S4: Detection and rejection. The detection camera 502 is used to detect whether there is a problem with the bracket. When the bracket needs to be rejected, the detection camera 502 starts the electric telescopic rod 504. The electric telescopic rod 504 drives the sliding extrusion block 505 to disengage from the extrusion column 207. At this time, the rotating round block 205 slides upward and contacts the friction plate 509. The friction plate 509 drives the rotating round block 205 to rotate. The rotation of the rotating round block 205 drives the bearing arc plate 206 to rotate. The bearing arc plate 206 rotates to dump the bracket into the waste bin 510 directly below.

[0051] A specific application of this embodiment is:

[0052] When using the detection device, first start the driving motor 11, and put the speaker bracket to be detected into the bearing arc plate 206 in turn. The output end of the driving motor 11 drives the conveying turntable 13 on the output shaft 12 to rotate. The rotation of the conveying turntable 13 drives the several bearing bases 201 on the conveying belt 14 to rotate. The bearing base 201 rotates and moves toward one end close to the storage box 15. When the squeezing column 207 is close to one end of the conveying belt 14 and is squeezed by the special-shaped squeezing block 211, the squeezing column 207 slides inward along the conveying belt 14. The squeezing column 207 drives the squeezing sheet 1 208 to move toward one end of the bracket. The squeezing sheet 1 208 drives the squeezing sheet 2 210 on the squeezing spring 209 to squeeze one end of the bracket. Under the squeezing action of the squeezing sheet 210, the bracket is fixed between the two squeezing sheets 210. This arrangement is conducive to the bracket inside the device. The stable movement prevents the bracket from sliding during the detection process, thereby improving the detection stability of the device; by setting the rotating cleaning structure 3, when the gear 301 is meshed with the rack 302, the gear 301 rotates, the rotation of the gear 301 drives the extrusion column 207 to rotate, the rotation of the extrusion column 207 drives the extrusion sheet 1 208 to rotate, the rotation of the extrusion sheet 1 208 drives the extrusion sheet 2 210 at one end of the extrusion spring 209 to rotate, the rotation of the extrusion sheet 210 drives the bracket to rotate, the rotation of the bracket makes the surface of the bracket rub against the several bristles at the bottom of the cleaning plate 304, such a setting is conducive to cleaning the dust on the surface of the bracket, avoiding the dust being mistakenly identified as particles during the particle detection process, and improving the detection accuracy of the device, on the other hand, the gear 301 drives the bracket to rotate, which is conducive to the bristles at the bottom of the cleaning plate 304 to fully clean the surface of the bracket, avoiding the omission of cleaning the surface of the bracket;

[0053] By setting the auxiliary detection mechanism 4, the extrusion column 207 and the special-shaped extrusion block 211 are squeezed against each other, and the extrusion column 207 drives the limit block 1 401 to move inward, and the limit block 1 401 drives the push plate 402 to move along the extrusion column 207 to one end close to the bracket, and the push plate 402 drives the sliding column 202 at one end of the linkage rod 403 to slide downward along the bearing base 201. At this time, the sliding column 202 drives the sliding plate 203 to squeeze the reset spring 404 downward, and the sliding plate 203 moves downward to drive the rotating round block 205 at one end of the connecting column 204 to move downward, and the rotating round block 205 moves downward to drive the bearing arc plate 206 to move downward, and the bearing arc plate 206 moves downward and disengages from the bottom of the bracket. This arrangement is conducive to making the rotating bracket disengage from the bearing arc plate 206, avoiding friction between the bracket rotation and the bearing arc plate 206, thereby avoiding friction damage to the bracket surface, and improving the production quality of the bracket; by setting the detection and rejection mechanism 5, when the bracket moves to the bottom of the detection camera 502, the detection camera 502 is detected. The head 502 uses a computer to detect whether there are injection molded particles left on the surface of the bracket. When it is detected that the bracket has quality defects, the program controls the electric telescopic rod 504 to shrink. The electric telescopic rod 504 shrinks and drives the sliding extrusion block 505 to move to the outside of the device housing 1. At this time, the sliding extrusion block 505 and the extrusion column 207 are separated from each other and squeezed. At this time, the extrusion column 207 slides outward to drive the extrusion sheet 210 on the extrusion spring 209 to separate from the two ends of the bracket, and the bracket falls back to the inside of the load-bearing arc plate 206. Under the rebound action of the spring 404, the sliding plate 203 drives the supporting arc plate 206 on the rotating block 205 to move upward. At this time, the rotating block 205 contacts the friction plate 509 at one end of the friction fixing rod 508. Under the friction action of the friction plate 509, the rotating block 205 drives the supporting arc plate 206 to rotate. At this time, the rotating block 205 rotates around the connecting column 204, and the supporting arc plate 206 rotates to dump the bracket into the waste box 510 directly below, thereby realizing the removal of defective products.
