Description

Technical Field

[0001] The utility model relates to the technical field of production line detection, and particularly relates to a defective product removing mechanism for an assembly production line. Background Art

[0002] The assembly production line is divided into an automatic assembly line and a manual assembly line. After the products are assembled and produced, labels need to be pasted on the surfaces of the products. On the automated label-pasting production line, after the labeling machine completes the labeling of the products, it is necessary to promptly remove the products that do not meet the labeling standards. Currently, this is completed through manual inspection and screening. However, manual operation is prone to fatigue, which easily leads to unqualified products entering the next process, thereby affecting the product qualification rate. Therefore, there is also a problem of low accuracy in manual screening and removal of defective products.

[0003] After retrieval, a utility model patent with the publication number CN209189286U specifically discloses a defective product removing device for a production line, which includes a mounting base. The mounting base is provided with a detection mechanism, a removing mechanism, and a positioning mechanism. The detection mechanism includes a shooting component and a processor electrically connected to the shooting component. The removing mechanism is electrically connected to the processor and is used to remove the unqualified products detected by the detection mechanism. The positioning mechanism is used to determine the detection position of the products on the production line reaching the detection mechanism and the removing position of the removing mechanism. This device uses a positioning mechanism to be arranged at the detection position of the detection mechanism and the removing position of the removing mechanism to accurately position the products, greatly improving the detection accuracy of the detection mechanism and the removing accuracy of the removing mechanism, thereby improving the accuracy of defective product removal by this device and improving the removal efficiency.

[0004] In the above patent, only by implementing a positioning mechanism at the detection mechanism and the removing position, the accuracy of defective product removal by the device is improved. However, during the production process, in order to save production line costs, enterprises need to produce different products on the same production line. The parts in the existing detection mechanism are not convenient for sensing detection and removal work on products of different heights and sizes, resulting in unqualified products being easily flowed out to customers, causing after-sales problems.

[0005] Therefore, it is very necessary for us to propose a defective product removing mechanism for an assembly production line to solve the above problems. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a defective product removing mechanism for an assembly production line. Through the mutual cooperation between the parts inside the material pushing mechanism, the appropriate position adjustment can be made according to the size of the products on the main body of the production line, and at the same time, the parts inside the detection mechanism are driven to adjust, so as to solve the problem that the parts in the existing detection mechanism are not convenient for sensing detection and removal work on products of different heights and sizes, resulting in unqualified products being easily flowed out to customers.

[0007] To achieve the above object, the present utility model provides the following technical solution: A defective product rejection mechanism for an assembly production line, including a main assembly line. On one side of the main assembly line, an auxiliary assembly line is installed and connected. On the other side of the main assembly line, a support plate is installed and fixed. At the top of the support plate, a pushing mechanism is connected and fixed. At the top of the pushing mechanism, a detection mechanism is connected and fixed, which penetrates into the interior of the pushing mechanism and extends to the top of the main assembly line.

[0008] Preferably, the pushing mechanism includes a fixed bracket, which is connected and fixed to the top of the support plate. Inside the cavity of the fixed bracket, a driving module is slidably connected. On one side of the driving module, a connecting shaft is rotatably connected and penetrates into the interior of the driving module. On the side of the connecting shaft away from the driving module, a connecting plate is connected and fixed. A torsion spring is sleeved on the outer wall of the connecting shaft and is located inside the driving module. On the outer wall of the connecting shaft on the side away from the connecting plate, a connecting gear is sleeved. At the top and bottom of the connecting gear, racks are respectively slidably connected and are located inside the driving module. One end of each rack is connected and fixed to a fixed block, which penetrates the driving module into the interior of the fixed bracket. At the top of the driving module, a connecting column is connected and fixed and penetrates to the top of the fixed bracket.

[0009] Preferably, the detection mechanism includes a fixed column, which is connected and fixed to the top of the fixed bracket and is sleeved on the outer wall of the connecting column. At the top of the fixed column, a movable column is connected and penetrates into the interior of the fixed column. At the top of the movable column, a fixing plate is connected and fixed. On the top of the fixing plate on the side away from the fixed column, a detection sensor is connected and fixed. On the top of the fixing plate, a sliding column is rotatably connected and penetrates through the fixing plate, the movable column to the interior of the fixed column. At the bottom of the movable column, a limiting plate is connected and fixed and is located inside the fixed column and is sleeved on the outer wall of the sliding column. On both sides of the sliding column, limiting blocks are connected and fixed and are slidably connected inside the fixing plate. Inside the movable column, a contraction spring is connected and is sleeved on the outer wall of the sliding column.

[0010] Preferably, at both ends of the inner cavity of the fixed bracket, chutes are opened. At both ends of the driving module, sliders matching the chutes are installed. At both ends of the inner wall of the fixed bracket, fixing grooves matching the fixed blocks are opened. On the side of the driving module close to the main assembly line, an electric push rod is connected and fixed.

[0011] Preferably, the racks are meshed with the connecting gear through tooth blocks. Both ends of the connecting plate are respectively connected and fixed to the connecting shaft and the driving module. The connecting shaft is rotatably connected to the driving module through a bearing.

[0012] Preferably, a limiting groove matching the limiting block is formed inside the fixing plate. A plurality of clamping blocks are fixedly connected to the outer wall of the limiting plate. A clamping groove matching the clamping blocks on the outer wall of the limiting plate is formed inside the fixing column. A limiting ring located inside the movable column is sleeved on the outer wall of the sliding column.

[0013] In the above technical solution, the technical effects and advantages provided by the present utility model are as follows:

[0014] 1. By rotating the connecting plate, the connecting plate drives the connecting shaft to squeeze the torsion spring to contract and rotate. The rotation of the connecting shaft drives the connecting gear to rotate. The rotation of the connecting gear drives the rack to move. The movement of the rack drives the fixed block to move. The fixed block moves from inside the fixed bracket to inside the drive module, releasing the position fixation between the drive module and the fixed bracket. Then, push the drive module to move. The movement of the drive module drives the electric push rod to move to a position matching the size and center of gravity of the product. Then, release the rotation of the connecting plate, so that the connecting shaft releases the extrusion of the torsion spring. The torsion spring resets and drives the connecting shaft to rotate and reset. The rotation of the connecting shaft drives the connecting gear to rotate in the reverse direction. The rotation of the connecting gear drives the rack to move, so that the movement of the rack drives the fixed block to move to inside the fixed bracket, completing the position fixation between the drive module and the fixed bracket, and thus completing the position adjustment operation of the drive module.

[0015] 2. The movement of the drive module drives the connecting column to move inside the fixed column. The movement of the connecting column squeezes the sliding column. The movement of the sliding column drives the limiting block to move. The movement of the limiting block drives the movable column to move inside the fixed column through the fixing plate. The movement of the movable column drives the limiting plate to move. The movement of the movable column drives the fixing plate to move. The movement of the fixing plate drives the detection sensor to move to an appropriate height for height adjustment according to the height of different products. After the detection sensor moves to an appropriate height, the limiting plate fixes the position of the movable column through the clamping blocks on the outer wall. At the same time, rotate the sliding column. The rotation of the sliding column drives the limiting block to rotate, so that the limiting block rotates out of the limiting groove, and the limiting ring on the outer wall of the sliding column releases the extrusion of the compression spring. The compression spring resets and pushes the sliding column to move, so that the sliding column moves to inside the movable column and moves away from the connecting column, leaving enough rising space between the movable column and the connecting column inside the fixed column, and thus completing the height adjustment of the detection sensor, improving the detection accuracy of unqualified products.

[0030] The working principle of this utility model:

[0031] Refer to the attached instructions Figures 1-4 , rotate the connecting plate 204. The connecting plate 204 drives the connecting shaft 203 to squeeze the torsion spring 205 to contract and rotate. The connecting shaft 203 rotates to drive the connecting gear 206 to rotate. The connecting gear 206 rotates to drive the rack 207 to move. The rack 207 moves to drive the fixing block 208 to move. The fixing block 208 moves from inside the fixing bracket 201 to inside the driving module 202, releasing the position fixation between the driving module 202 and the fixing bracket 201. Then push the driving module 202 to move. The driving module 202 moves to drive the electric push rod to move to a position matching the size and center of gravity of the product. Then release the rotation of the connecting plate 204, so that the connecting shaft 203 releases the extrusion of the torsion spring 205. The torsion spring 205 resets to drive the connecting shaft 203 to rotate and reset. The connecting shaft 203 rotates to drive the connecting gear 206 to rotate in the reverse direction. The connecting gear 206 rotates to drive the rack 207 to move, so that the rack 207 moves to drive the fixing block 208 to move into the fixing bracket 201, completing the position fixation between the driving module 202 and the fixing bracket 201, and thus completing the position adjustment operation of the driving module 202;

[0032] Refer to the attached instructions Figures 1-4, the driving module 202 moves to drive the connecting column 209 to move inside the fixed column 301. The movement of the connecting column 209 squeezes the sliding column 306. The movement of the sliding column 306 causes the limiting block 307 to move. The movement of the limiting block 307 drives the movable column 302 to move inside the fixed column 301 through the fixed plate 303. The movement of the movable column 302 drives the limiting plate 305 to move. The movement of the movable column 302 drives the fixed plate 303 to move. The movement of the fixed plate 303 drives the detection sensor 304 to move to a suitable height for height adjustment according to the height of different products. After the detection sensor 304 moves to a suitable height, the limiting plate 305 fixes the position of the movable column 302 through the clamping block on the outer wall. At the same time, the sliding column 306 is rotated. The rotation of the sliding column 306 drives the limiting block 307 to rotate, causing the limiting block 307 to rotate out of the limiting groove, so that the limiting ring on the outer wall of the sliding column 306 releases the extrusion of the compression spring 308. The compression spring 308 resets and pushes the sliding column 306 to move, so that the sliding column 306 moves into the movable column 302 and moves away from the connecting column 209, leaving enough rising space between the movable column 302 and the connecting column 209 inside the fixed column 301, thus completing the height adjustment of the detection sensor 304 and improving the detection accuracy of unqualified products.

[0033] Only some exemplary embodiments of the present invention have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways.
