A PCB board end riveting device and its riveting method

Abstract

The present invention relates to the technical field of PCB board end riveting, and discloses a PCB board end riveting device and its riveting method, including an equipment box body, and a riveting workbench is fixedly connected above the equipment box body. By setting a downward pressing and fixing mechanism in the present invention, after the PCB board to be processed is installed, the hydraulic rod is started to drive the pushing plate to slide downward along the sliding rod. The downward sliding of the pushing plate drives several riveting heads on the riveting base to slide downward. The pushing plate drives the racks at both ends to slide downward, the racks drive the gears to rotate, and the gears drive the fixed screw rod to rotate. At this time, the fixed screw rod drives the sliding extrusion plate to move along the inner wall of the riveting workbench towards the end close to the PCB board to be processed. At this time, the sliding extrusion plate moves to squeeze the extrusion spring, and the extrusion spring is squeezed and contracts. As the extrusion spring contracts, the elastic force increases, so the extrusion force of the extrusion spring on the second fixing plate increases. Such a setting is beneficial to increasing the clamping force of the second fixing plate on the edge of the PCB board to be processed.

[0014] The riveting method of the PCB end riveting equipment includes the following steps:

[0015] S1: Adjustment device. When the PCB board end riveting device is used, the position of the riveting head on the riveting base is first adjusted according to the model of the PCB board, and the corresponding position of the riveting head on the riveting base is adjusted according to the position of the riveting holes on the PCB boards of different models. The riveting head is moved so that the riveting head slides inside the adjustment slot. When the adjustment is completed, the tightening handle is turned to drive several extrusion plates on the tightening screw rod to slide inside the adjustment slot. At this time, the extrusion plates squeeze the riveting head inside the adjustment slot. This arrangement is conducive to fixing the riveting head.

[0016] S2: Install and fix the PCB board, press the pressing column to make it slide inside the riveting workbench, and the riveting workbench drives the driving block at one end of the linkage rod to squeeze the telescopic rod. At this time, the telescopic rod shrinks, and the driving block drives the fixed plate 2 to move toward the two ends of the riveting workbench. At this time, the PCB board to be processed is placed in the discharge trough. When the pressing column is released, the extrusion spring drives the fixed plate 2 to move toward the edge of the PCB board to be processed under the extrusion effect of the extrusion spring. This setting is conducive to the preliminary fixing of the PCB board to be processed on the riveting workbench;

[0017] S3: Auxiliary fixation, the rack drives the gear to rotate, the gear drives the fixed screw to rotate, at this time the fixed screw drives the sliding extrusion plate to move along the inner wall of the riveting workbench toward one end of the PCB to be processed, the sliding extrusion plate moves to squeeze the extrusion spring, the extrusion spring shrinks and the elastic force increases, and the extrusion force of the extrusion spring on the fixed plate 2 increases, so this setting is conducive to increasing the clamping force of the fixed plate 2 on the edge of the PCB to be processed;

[0018] S4: Auxiliary riveting. When the push plate and the extrusion column are extruded, the extrusion column is driven by the extrusion to drive the sliding block 1 to move downward along the sliding groove 1. The extrusion column drives the sliding block 2 at one end of the linkage rod 2 to slide along the sliding groove 2 toward the central axis of the riveting workbench. The sliding block 2 drives the auxiliary riveting plate at one end of the linkage rod 3 to slide upward along the discharge trough. The auxiliary riveting plate drives the rivet to cooperate with the riveting head for riveting. This arrangement is conducive to the riveting device to rivet from both sides of the PCB board to be processed.

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

[0020] (1) The present invention provides a downward pressing fixing mechanism. When the PCB to be processed is installed, the hydraulic rod is started to drive the push plate to slide downward along the sliding rod. The push plate slides downward to drive a plurality of riveting heads on the riveting base to slide downward. The push plate drives the racks at both ends to slide downward. The rack drives the gear to rotate. The gear drives the fixed screw to rotate. At this time, the fixed screw drives the sliding extrusion plate to move along the inner wall of the riveting workbench toward one end of the PCB to be processed. At this time, the sliding extrusion plate moves to squeeze the extrusion spring. The extrusion spring is squeezed and contracted. The contraction elastic force of the extrusion spring increases. Then, the extrusion force of the extrusion spring on the fixed plate 2 increases. Such a configuration is conducive to increasing the clamping force of the fixed plate 2 on the edge of the PCB to be processed, thereby enhancing the clamping effect of the fixed plate 2 on the edge of the PCB to be processed.

[0021] (2) According to the present invention, when the PCB board end riveting device is used, the position of the riveting head on the riveting base is first adjusted according to the model of the PCB board, and the corresponding position of the riveting head on the riveting base is adjusted according to the position of the riveting holes on the PCB boards of different models. The riveting head is made to slide inside the adjustment groove by toggling the riveting head. When the adjustment is completed, the tightening handle is turned to drive the plurality of extrusion plates on the tightening screw rod to slide inside the adjustment groove. At this time, the extrusion plates squeeze the riveting head inside the adjustment groove. Such a setting is conducive to fixing the riveting head, so that the riveting head will not move during the riveting process, ensuring that the riveting head is accurately docked with the riveting holes on the PCB board to be processed, thereby improving the working stability of the device. When the PCB board to be processed needs to be placed inside the discharge trough on the riveting workbench, first First, press the pressing column on the riveting workbench to make it slide into the inside of the riveting workbench. At this time, the riveting workbench drives the driving blocks at one end of the linkage rod to squeeze the telescopic rod. At this time, the telescopic rod contracts, and the driving block drives the fixed plate to move toward the two ends of the riveting workbench. At this time, put the PCB board to be processed into the discharge trough. When the pressing column is released, the extrusion spring drives the fixed plate to move toward the edge of the PCB board to be processed under the extrusion effect of the extrusion spring. This arrangement is conducive to preliminarily fixing the PCB board to be processed on the riveting workbench, so that the PCB board to be processed on the riveting workbench is preliminarily fixed inside the discharge trough on the riveting workbench. This arrangement is conducive to positioning the PCB board to be processed inside the discharge trough to avoid movement of the PCB board to be processed during the riveting process.

[0022] (3) In the present invention, the sliding extrusion plate slides inside the riveting workbench, squeezing the air in the inner cavity of the riveting workbench. The gas in the inner cavity of the riveting workbench is squeezed and discharged along the air outlet holes on the second fixing plate, and then the gas discharged along the air outlet holes is further discharged through the riveting holes on the PCB to be processed. The air discharged from the riveting holes is conducive to taking away the dust inside the riveting holes, thereby improving the riveting quality of the product. When the riveting is completed, a certain high temperature will be generated at the riveting holes. At this time, the hydraulic rod moves upward, and the sliding extrusion plate inside the riveting workbench moves towards the end away from the PCB to be processed. At this time, the sliding extrusion plate pumps the air in the inner cavity of the riveting workbench, and the air passes through the riveting holes on the PCB to be processed and then through the air outlet holes on the second fixing plate again. This setting is conducive to reducing the temperature at the position of the riveting holes on the PCB to be processed, thereby ensuring that the PCB to be processed is not affected by the high temperature.

[0023] (4) In the present invention, by setting an auxiliary riveting mechanism, the hydraulic rod drives the pushing plate to move downward. When the pushing plate squeezes the extrusion column, the extrusion column is squeezed and drives the first sliding block to move downward along the first sliding groove. The extrusion column drives the second sliding block at one end of the linkage rod two to slide towards the central axis of the riveting workbench along the second sliding groove. At this time, the second sliding block drives the auxiliary riveting plate at one end of the linkage rod three to slide upward along the feeding groove. At this time, the auxiliary riveting plate drives the rivet to cooperate with the riveting head for riveting. This setting is conducive to the riveting device to perform riveting from both sides of the PCB to be processed, which is conducive to improving the riveting efficiency.

[0024] Of course, it is not necessary for any product implementing the present invention to achieve all the above advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0039] Example 1, please refer to Figure 1 - Figure 6As shown, the present invention is a PCB board end riveting device and a riveting method thereof, comprising an equipment box 1, a riveting workbench 11 is fixedly connected to the top of the equipment box 1, a plurality of support rods 12 are fixedly connected to the top of the riveting workbench 11, a fixed plate 13 is fixedly connected to one end of the support rod 12 away from the riveting workbench 11, a hydraulic rod 14 is fixedly connected to the bottom of the fixed plate 13, a material discharge trough 15 is provided on the top of the riveting workbench 11, a PCB board 16 to be processed is arranged inside the material discharge trough 15, and further comprising:

[0040] The riveting mechanism 2 includes a pushing plate 201 fixedly connected to the end of the hydraulic rod 14 away from the fixed plate 13, a riveting base 202 is fixedly connected to the side of the pushing plate 201 away from the hydraulic rod 14, and a plurality of sliding rods 203 are fixedly connected directly above the riveting workbench 11, and the pushing plate 201 is slidably connected to the sliding rods 203.

[0041] The riveting mechanism 2 also includes a plurality of adjusting slots 204 provided on the riveting base 202, a plurality of riveting heads 205 are slidably connected inside the adjusting slots 204, a tightening screw rod 206 is rotatably connected inside the riveting base 202, a tightening handle 207 is fixedly connected to the end of the tightening screw rod 206 away from the riveting base 202, a plurality of extrusion plates 208 are rotatably connected to the tightening screw rod 206, and the extrusion plates 208 are slidably connected inside the adjusting slots 204. The function of this component is that when the PCB board end riveting device is used, the position of the riveting head 205 on the riveting base 202 is first adjusted according to the model of the PCB board, and the position of the riveting head 205 on the riveting base 202 is adjusted according to the model of the PCB board, and the position of the riveting head 205 on the riveting base 202 is adjusted according to the model of the PCB board. The position of the riveting hole on the plate adjusts the position of the corresponding riveting head 205 on the riveting base 202. The riveting head 205 is made to slide inside the adjusting groove 204 by toggling the riveting head 205. When the adjustment is completed, the tightening handle 207 is rotated to drive the several squeezing plates 208 on the tightening screw rod 206 to slide inside the adjusting groove 204. At this time, the squeezing plate 208 squeezes the riveting head 205 inside the adjusting groove 204. This arrangement is conducive to fixing the riveting head 205, so that the riveting head 205 will not move during the riveting process, ensuring that the riveting head 205 is accurately docked with the riveting hole on the PCB board 16 to be processed, thereby improving the stable performance of the device.

[0042] A material discharge fixing mechanism 3 is arranged inside the riveting workbench 11, and the material discharge fixing mechanism 3 includes a pressing column 301 slidably connected to the bottom of the riveting workbench 11, and one end of the pressing column 301 close to the inside of the riveting workbench 11 is rotatably connected to a plurality of linkage rods 302, and a plurality of telescopic rods 303 are fixedly connected to the inside of the riveting workbench 11.

A plurality of extrusion springs 306 are fixedly connected to one side of the second fixing plate 304 away from the PCB board 16 to be processed. The function of this component is that when it is necessary to place the PCB board 16 to be processed into the blanking groove 15 on the riveting workbench 11, first press the pressing column 301 on the riveting workbench 11. Pressing the pressing column 301 causes the pressing column 301 to slide into the riveting workbench 11. At this time, the riveting workbench 11 drives the driving block 305 at one end of the first linkage rod 302 to extrude the telescopic rod 303. At this time, the telescopic rod 303 contracts, and the driving block 305 drives the second fixing plate 304 to move towards both ends of the riveting workbench 11. At this time, the PCB board 16 to be processed is placed into the blanking groove 15. When the pressing column 301 is released, under the extrusion of the extrusion spring 306, the extrusion spring 306 drives the second fixing plate 304 to move towards the edge of the PCB board 16 to be processed. Such a setting is beneficial to initially fix the PCB board 16 to be processed on the riveting workbench 11, so that the PCB board 16 to be processed on the riveting workbench 11 is initially fixed inside the blanking groove 15 on the riveting workbench 11. Such a setting is beneficial to position the PCB board 16 to be processed inside the blanking groove 15 and avoid the movement of the PCB board 16 to be processed during the riveting process.

[0044] Embodiment 2, the difference feature from Embodiment 1 is that; as Figure 1 - Figure 10As shown in the figure, a downward pressing and fixing mechanism 4 is arranged inside the riveting workbench 11. The downward pressing and fixing mechanism 4 includes a plurality of racks 401 fixedly connected to the bottom of the pushing plate 201. A plurality of fixed lead screws 402 are rotatably connected to the inner wall of the riveting workbench 11. One end of the fixed lead screw 402 close to the rack 401 is fixedly connected with a gear 403. The gear 403 meshes with the rack 401. The other end of the fixed lead screw 402 away from the rack 401 is rotatably connected with a sliding extrusion plate 404. The sliding extrusion plate 404 is slidably connected with the riveting workbench 11. One side of the sliding extrusion plate 404 away from the gear 403 is fixedly connected with a compression spring 306. A plurality of air holes 405 are formed in the second fixing plate 304. The function of this component is to set the downward pressing and fixing mechanism 4. After the PCB board 16 to be processed is installed, the hydraulic rod 14 is started to drive the pushing plate 201 to slide downward along the sliding rod 203. The downward sliding of the pushing plate 201 drives a plurality of riveting heads 205 on the riveting base 202 to slide downward. The pushing plate 201 drives the racks 401 at both ends to slide downward. The rack 401 drives the gear 403 to rotate. The gear 403 drives the fixed lead screw 402 to rotate. At this time, the fixed lead screw 402 drives the sliding extrusion plate 404 to move along the inner wall of the riveting workbench 11 towards one end close to the PCB board 16 to be processed. At this time, the sliding extrusion plate 404 moves to compress the compression spring 306. The compression spring 306 is compressed and contracted. The elastic force of the compression spring 306 increases when it is compressed. Then the extrusion force of the compression spring 306 on the second fixing plate 304 increases. Such a setting is beneficial to increasing the clamping force of the second fixing plate 304 on the edge of the PCB board 16 to be processed, thereby enhancing the clamping effect of the second fixing plate 304 on the edge of the PCB board 16 to be processed. In addition, the sliding extrusion plate 404 slides inside the riveting workbench 11, compressing the air in the inner cavity of the riveting workbench 11. The gas in the inner cavity of the riveting workbench 11 is compressed and discharged along the air holes 405 on the second fixing plate 304. The gas discharged along the air holes 405 is then discharged through the riveting holes on the PCB board 16 to be processed. The air discharged from the riveting holes is beneficial to taking away the dust inside the riveting holes, thereby improving the riveting quality of the product; when the riveting is completed, a certain high temperature will be generated at the riveting holes. At this time, the hydraulic rod 14 moves upward. At this time, the sliding extrusion plate 404 inside the riveting workbench 11 moves towards one end away from the PCB board 16 to be processed. At this time, the sliding extrusion plate 404 pumps the air in the inner cavity of the riveting workbench 11. The air passes through the riveting holes on the PCB board 16 to be processed and then through the air holes 405 on the second fixing plate 304 again. Such a setting is beneficial to reducing the temperature at the position of the riveting holes on the PCB board 16 to be processed, thereby ensuring that the PCB board 16 to be processed is not affected by high temperature.

[0053] When the PCB board end riveting device is used, firstly, the position of the riveting head 205 on the riveting base 202 is adjusted according to the model of the PCB board, and the corresponding position of the riveting head 205 on the riveting base 202 is adjusted according to the position of the riveting holes on the different models of PCB boards. The riveting head 205 is moved so that the riveting head 205 slides inside the adjustment groove 204. When the adjustment is completed, the tightening handle 207 is turned to drive the plurality of extrusion plates 208 on the tightening screw rod 206 to slide inside the adjustment groove 204. At this time, the extrusion plates 20 8 squeezes the riveting head 205 inside the adjusting groove 204. This arrangement is conducive to fixing the riveting head 205, so that the riveting head 205 will not move during the riveting process, ensuring that the riveting head 205 is accurately docked with the riveting hole on the PCB board 16 to be processed, thereby improving the working stability of the device; when it is necessary to put the PCB board 16 to be processed into the discharge groove 15 on the riveting workbench 11, first press the pressing column 301 on the riveting workbench 11, press the pressing column 301 so that the pressing column 301 moves toward the riveting The workbench 11 slides inside, and the riveting workbench 11 drives the driving block 305 at one end of the linkage rod 1 302 to squeeze the telescopic rod 303. At this time, the telescopic rod 303 contracts, and the driving block 305 drives the fixed plate 2 304 to move toward the two ends of the riveting workbench 11. At this time, the PCB board 16 to be processed is placed in the discharge groove 15. When the pressing column 301 is released, the extrusion spring 306 drives the fixed plate 2 304 to move toward the edge of the PCB board 16 to be processed under the extrusion effect of the extrusion spring 306. This arrangement is advantageous. The PCB board 16 to be processed on the riveting workbench 11 is initially fixed, so that the PCB board 16 to be processed on the riveting workbench 11 is initially fixed inside the material discharge groove 15 on the riveting workbench 11. This arrangement is conducive to positioning the PCB board 16 to be processed inside the material discharge groove 15, and avoiding the movement of the PCB board 16 to be processed during the riveting process. At this time, the rivet is then placed into the several riveting holes on the PCB board 16 to be processed, and the rivet falls on the auxiliary riveting plate 510 at the bottom of the PCB board 16 to be processed;

[0054] By setting the downward pressing and fixing mechanism 4, after the PCB board 16 to be processed is installed, the hydraulic rod 14 is started to drive the pushing plate 201 to slide downward along the sliding rod 203. The downward sliding of the pushing plate 201 drives several riveting heads 205 on the riveting base 202 to slide downward. The pushing plate 201 drives the racks 401 at both ends to slide downward. The racks 401 drive the gear 403 to rotate. The gear 403 drives the fixed screw rod 402 to rotate. At this time, the fixed screw rod 402 drives the sliding extrusion plate 404 to move along the inner wall of the riveting workbench 11 towards the end close to the PCB board 16 to be processed. At this time, the sliding extrusion plate 404 moves to squeeze the extrusion spring 306. The extrusion spring 306 is squeezed and contracts. The elastic force of the extrusion spring 306 increases when it contracts. Then the extrusion force of the extrusion spring 306 on the second fixing plate 304 increases. Such a setting is beneficial to increasing the clamping force of the second fixing plate 304 on the edge of the PCB board 16 to be processed, thereby enhancing the clamping effect of the second fixing plate 304 on the edge of the PCB board 16 to be processed. In addition, the sliding extrusion plate 404 slides inside the riveting workbench 11, squeezing the air in the inner cavity of the riveting workbench 11. The gas in the inner cavity of the riveting workbench 11 is squeezed and discharged along the air outlet holes 405 on the second fixing plate 304, and then discharged through the riveting holes on the PCB board 16 to be processed. The air discharged from the riveting holes is beneficial to taking away the dust inside the riveting holes, thereby improving the riveting quality of the product. When the riveting is completed, a certain high temperature will be generated at the riveting holes. At this time, the hydraulic rod 14 moves upward. At this time, the sliding extrusion plate 404 inside the riveting workbench 11 moves towards the end away from the PCB board 16 to be processed. At this time, the sliding extrusion plate 404 pumps the air in the inner cavity of the riveting workbench 11. The air passes through the riveting holes on the PCB board 16 to be processed and then through the air outlet holes 405 on the second fixing plate 304 again. Such a setting is beneficial to reducing the temperature at the position of the riveting holes on the PCB board 16 to be processed, thereby ensuring that the PCB board 16 to be processed is not affected by high temperature. By setting the auxiliary riveting mechanism 5, the hydraulic rod 14 drives the pushing plate 201 to move downward. When the pushing plate 201 is squeezed by the extrusion column 504, the extrusion column 504 is squeezed to drive the sliding block one 502 to slide downward along the sliding groove one 501. The extrusion column 504 drives the sliding block two 508 at one end of the linkage rod two 505 to slide towards the central axis of the riveting workbench 11 along the sliding groove two 507. At this time, the sliding block two 508 drives the auxiliary riveting plate 510 at one end of the linkage rod three 509 to slide upward along the material placing groove 15. At this time, the auxiliary riveting plate 510 drives the rivet to cooperate with the riveting head 205 for riveting. Such a setting is beneficial to the riveting device to carry out riveting from both sides of the PCB board 16 to be processed, and such a setting is beneficial to improving the riveting efficiency.
