Description

Technical Field

[0001] This utility model relates to the field of testing equipment, specifically to a final assembly disc testing machine. Background Technology

[0002] In modern manufacturing, rigorous testing of workpiece dimensions, appearance, and performance indicators after production is crucial for ensuring product quality and meeting customer needs. To achieve continuous automated workpiece testing, traditional testing equipment mostly uses chain-driven transmission devices to transport workpieces. This device continuously circulates the workpiece from the testing area to the testing station, and after testing, it removes the workpiece while simultaneously introducing the next workpiece to be tested, thus forming a highly efficient automated testing process. However, with the increasing demands for product quality in the manufacturing industry, the limitations of chain-driven transmission devices in practical applications have gradually become apparent.

[0003] First, chain-driven transmission devices suffer from poor stability and inconsistent precision. Specifically, since the product station is fixed to the chain, factors such as the chain's pitch error, pitch wear, and longitudinal deviation directly affect the positioning accuracy of the product station. This accumulation of errors, especially on high-speed, continuous production lines, is significantly amplified, leading to inaccurate workpiece positioning at the inspection station. Even more problematic is that when the workpiece is placed laterally on the chain, its irregular shape can cause the workpiece center to deviate significantly from the ideal position, further complicating the alignment between the inspection device and the workpiece, thus affecting the accuracy and reliability of the inspection.

[0004] Secondly, chain-driven transmission devices often lack sufficient design flexibility, especially when handling workpieces with disputed inspection results. Specifically, after inspection, workpieces are usually sent directly to the next process or processed for unloading. Chain-driven transmission devices lack a mechanism to return disputed workpieces to the inspection front for re-inspection, which not only increases the risk of misjudgment but also reduces the accuracy of inspection results.

[0005] In view of the above problems, it is particularly important to develop a final assembly disc inspection machine, which aims to overcome the limitations of chain-driven devices and improve the accuracy of inspection. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] This invention provides a final assembly disc inspection machine, which can at least solve the technical problem of how to improve inspection accuracy.

[0008] (II) Technical Solution

[0009] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a final assembly disc inspection machine, comprising:

[0010] frame;

[0011] The indexing turntable is mounted on the machine frame, and several stations for horizontally placing workpieces are distributed in a ring at intervals on the indexing turntable.

[0012] The feeding device is located on the frame and is used to transport the workpieces one by one to each station of the indexing turntable;

[0013] A vision inspection device is located above the indexing turntable and is positioned opposite one of the workstations. The vision inspection device is used to inspect the appearance and dimensions of the workpieces at the corresponding workstation.

[0014] The unloading device is located outside the indexing turntable and downstream of the vision inspection device. The unloading device is used to classify and unload the workpieces that have been inspected on the indexing turntable.

[0015] Further configuration: The aforementioned feeding device includes a hopper, a lifting conveyor chain, and a feeding conveyor belt. The lifting conveyor chain is inclined upwards, with its lower end connected to the hopper and its upper end connected to the feeding end of the feeding conveyor belt. The discharge end of the feeding conveyor belt is connected to the indexing turntable. The feeding conveyor belt is provided with a conveying channel for individual workpieces to pass through.

[0016] The hopper is used to supply workpieces to the lifting conveyor chain, which in turn lifts and transports the workpieces to the feeding conveyor belt, which then transports the workpieces one by one to the indexing turntable.

[0017] Furthermore, the aforementioned feeding device also includes a dispersing mechanism, which is located above the feeding conveyor belt and at the front end of the conveying channel. The dispersing mechanism is used to disperse the workpieces on the feeding conveyor belt and to flip the vertically placed workpieces on the feeding conveyor belt to be placed horizontally.

[0018] Further, the aforementioned decentralized institutions include:

[0019] The brush head is positioned above the feed conveyor belt and at the front end of the conveying channel. The distance between the brush head and the feed conveyor belt is greater than the height of the workpiece placed laterally, but less than the height of the workpiece placed vertically.

[0020] A rotary drive unit, mounted on the frame and connected to the brush head drive, is used to drive the brush head to rotate away from the conveying channel.

[0021] Furthermore, the aforementioned feeding conveyor belt is also equipped with several guide plates. The guide plates are located at the rear end of the conveying channel and are inclined to the feeding direction of the feeding conveyor belt so that the workpieces on the feeding conveyor belt are arranged in a "Z" shape.

[0022] In a further configuration, a return plate is provided on one side of the aforementioned feeding conveyor belt. The return plate is located at the front end of the conveying channel and extends downward at an angle from the feeding conveyor belt. The lower end of the return plate is connected to the hopper.

[0023] Furthermore, the aforementioned feeding device also includes:

[0024] The feeding disc is located above the junction of the feeding conveyor belt and the indexing turntable, and the outer periphery of the feeding disc is provided with multiple toothed grooves at intervals.

[0025] The feeding disc drive is mounted on the frame and is connected to the feeding disc for transmission. The feeding disc drive is used to drive the feeding disc to rotate toward the indexing turntable, so as to drive the workpiece on the feeding conveyor belt to move toward the indexing turntable.

[0026] Furthermore, the aforementioned assembly disc inspection machine also includes a limiting frame, which is located above the indexing turntable and upstream of the vision inspection device. The limiting frame is provided with a limiting channel for limiting the position of the workpiece on the indexing turntable, and the diameter of the limiting channel is gradually reduced along the rotation direction of the indexing turntable.

[0027] Further, the aforementioned feeding device includes:

[0028] The air blowing mechanism includes two feeding channels, which are spaced apart on the outside of the indexing turntable. The air blowing mechanism includes two air blowing pipes, which are located above the indexing turntable. The air outlets of the two air blowing pipes are respectively directed towards the two feeding channels. The air blowing mechanism is used to blow qualified and unqualified workpieces on the indexing turntable into the two feeding channels respectively.

[0029] The return conveyor belt and guide plate are located between the indexing turntable and the feeding device, and downstream of the two unloading channels. The return conveyor belt is used to transport workpieces with disputed inspection results to the feeding device. The guide plate is located above the indexing turntable and extends towards the return conveyor belt. The guide plate is used to guide the workpieces on the indexing turntable to move onto the return conveyor belt.

[0030] (III) Beneficial Effects

[0031] Compared with the prior art, the assembly disc inspection machine provided by this utility model has the following beneficial effects:

[0032] In use, the assembly disc inspection machine provided by this utility model employs a feeding device to transport workpieces one by one, while the indexing turntable rotates, allowing each station of the turntable to alternately align with the discharge end of the feeding device, thus conveying the workpieces to their respective stations. During the rotation of the indexing turntable, when the workpiece on it is positioned relative to the vision inspection device, the vision inspection device checks whether the workpiece's appearance, dimensions, and other performance indicators meet quality requirements. After inspection, the indexing turntable rotates again, aligning the inspected workpiece with the unloading device, and simultaneously aligning the next workpiece to be inspected with the vision inspection device. Finally, the unloading device sorts and unloads the workpieces according to the inspection results for subsequent unified processing by personnel. It can be seen that this assembly disc inspection machine, by replacing the chain-type transmission device with an indexing turntable, transports the workpieces to be inspected to the vision inspection device for inspection, while simultaneously transporting the inspected workpieces to the unloading device for sorting and unloading. This achieves precise transport and alignment of workpieces, overcomes the limitations of the chain-type transmission device, and effectively improves the accuracy and reliability of the inspection.

[0044] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0045] This invention provides a final assembly disc inspection machine to address the problem of how to improve inspection accuracy.

[0046] See Figure 1 As shown, Figure 1 The image shown is a perspective view of the assembly disc inspection machine in the embodiment. The assembly disc inspection machine includes a frame 1, an indexing turntable 2, a feeding device 3, a vision inspection device 4, and a unloading device 5.

[0047] The indexing turntable 2 is mounted on the frame 1, and the indexing turntable 2 has several stations 21 arranged in a ring at intervals for horizontally placing the workpiece 9.

[0048] The feeding device 3 is installed on the frame 1 and is used to transport the workpieces 9 one by one to each station 21 of the indexing turntable 2.

[0049] The vision inspection device 4 is located above the indexing turntable 2 and is positioned opposite one of the workstations 21. The vision inspection device 4 is used to inspect the appearance and dimensions of the workpiece 9 at the corresponding workstation 21.

[0050] The unloading device 5 is installed on the outside of the indexing turntable 2 and is located downstream of the vision inspection device 4. The unloading device 5 is used to classify and unload the inspected workpieces 9 on the indexing turntable 2.

[0051] When the assembly disc inspection machine of the above technical solution is in use, the feeding device 3 conveys the workpieces 9 one by one, while the indexing turntable 2 rotates so that each station 21 of the indexing turntable 2 alternately connects with the discharge end of the feeding device 3, thereby conveying the workpieces 9 to each station 21; during the rotation of the indexing turntable 2, when the workpiece 9 on it is in position relative to the vision inspection device 4, the vision inspection device 4 detects whether the appearance, size and other performance indicators of the workpiece 9 meet the quality requirements; after the inspection is completed, the indexing turntable 2 rotates again, so that the inspected workpiece 9 is in position relative to the unloading device 5, and at the same time, the next workpiece 9 to be tested is in position relative to the vision inspection device 4; finally, the unloading device 5 sorts and unloads the workpiece 9 according to the inspection results, so that the staff can process it uniformly later. As can be seen, the assembly disc inspection machine replaces the chain-type transmission device with the indexing turntable 2 to transport the workpiece 9 to be inspected to the vision inspection device 4 for inspection, and at the same time transports the inspected workpiece 9 to the unloading device 5 for sorting and unloading. This can achieve precise transport and alignment of the workpiece 9, overcome the limitations of the chain-type transmission device, and thus effectively improve the accuracy and reliability of the inspection.

[0052] The aforementioned visual inspection device 4 can use existing visual inspection devices such as CCD cameras. The workpiece 9 is placed horizontally, which makes the center of gravity more stable and facilitates the stable transport of the workpiece 9, achieving precise transport and alignment of the workpiece 9.

[0053] See Figure 1As shown, in one embodiment of the feeding device 3, the feeding device 3 includes a hopper 31, a lifting conveyor chain 32, and a feeding conveyor belt 33. The lifting conveyor chain 32 is inclined upward. The lower end of the lifting conveyor chain 32 is connected to the hopper 31, and the upper end of the lifting conveyor chain 32 is connected to the feed end of the feeding conveyor belt 33. The discharge end of the feeding conveyor belt 33 is connected to the indexing turntable 2. The feeding conveyor belt 33 is provided with a conveying channel 331 for individual workpieces 9 to pass through. The hopper 31 is used to supply workpieces 9 to the lifting conveyor chain 32, the lifting conveyor chain 32 is used to lift and convey the workpieces 9 onto the feeding conveyor belt 33, and the feeding conveyor belt 33 is used to convey the workpieces 9 one by one onto the indexing turntable 2. Thus, during loading, firstly, the worker pours a large number of workpieces 9 into the hopper 31; then, the hopper 31 conveys several workpieces 9 to the lifting conveyor chain 32, which lifts and conveys the workpieces 9 to the feeding conveyor belt 33; finally, the feeding conveyor belt 33 conveys the workpieces 9, and the conveying channel 331 restricts the workpieces 9 on the feeding conveyor belt 33 to be arranged one by one, thereby conveying the workpieces 9 one by one to the indexing turntable 2. It can be seen that when the loading device 3 loads workpieces 9, the worker can directly pour the workpieces 9 into the lower hopper 31, which is then lifted and conveyed to the feeding conveyor belt 33 by the lifting conveyor chain 32, without manual lifting. Moreover, the workpieces 9 on the feeding conveyor belt 33 can be loaded one by one through the conveying channel 331 without manual adjustment, greatly saving manpower and improving production efficiency.

[0054] The aforementioned lifting conveyor chain 32 can use an existing chain-driven lifting conveyor.

[0055] See Figure 1 and Figure 2 As shown, Figure 2 This is a partial structural diagram of the dispersing mechanism and the feeding conveyor belt in the embodiment. Based on the above embodiment, the feeding device 3 further includes a dispersing mechanism 34. The dispersing mechanism 34 is installed above the feeding conveyor belt 33 and located at the front end of the conveying channel 331. The dispersing mechanism 34 is used to disperse the workpieces 9 on the feeding conveyor belt 33 and flip the vertically placed workpieces 9 on the feeding conveyor belt 33 to be placed horizontally. In this way, since the lifting conveyor chain 32 will simultaneously lift multiple workpieces 9 onto the feeding conveyor belt 33, resulting in multiple workpieces 9 being stacked together, in order to facilitate the one-by-one conveying of the workpieces 9, the feeding device 3, through the dispersing mechanism 34, can disperse the stacked workpieces 9 and flip the workpieces 9 vertically placed on the feeding conveyor belt 33 to be placed horizontally, so that the workpieces 9 can pass through the conveying channel 331 one by one.

[0056] See Figure 1 and Figure 2As shown, in one embodiment of the dispersing mechanism 34, the dispersing mechanism 34 includes a brush head 341 and a rotary drive member 342. The brush head 341 is mounted above the feed conveyor belt 33 and located at the front end of the conveying channel 331. The distance between the brush head 341 and the feed conveyor belt 33 is greater than the lateral height of the workpiece 9, but less than the vertical height of the workpiece 9. The rotary drive member 342 is mounted on the frame 1 by means of screwing or welding, and is drively connected to the brush head 341. The rotary drive member 342 is used to drive the brush head 341 to rotate in a direction away from the conveying channel 331. Thus, when workpiece 9 is conveyed to the dispersing mechanism 34 by the feeding conveyor belt 33, workpiece 9 placed horizontally can pass smoothly under the brush head 341 and then enter the conveying channel 331, while workpiece 9 placed vertically will be blocked by the brush head 341. At the same time, the rotation drive 342 drives the brush head 341 to rotate away from the conveying channel 331. The brush head 341 will cause the vertically placed workpiece 9 to flip to be placed horizontally, so that it can pass under the brush head 341. The dispersing mechanism 34 can effectively prevent the brush head 341 from scratching or damaging the workpiece 9 through soft contact with the brush head 341.

[0057] The brush head 341 can use a soft shaft such as an existing bristle brush or sponge brush. The rotary drive 342 can use an existing rotary cylinder or rotary motor, and its output end is connected to one end of the brush head 341 by means of screwing or welding.

[0058] See Figure 1 As shown, based on the above embodiment of the feeding conveyor belt 33, the feeding conveyor belt 33 is further provided with several guide plates 332. The guide plates 332 are located at the rear end of the conveying channel 331, and are inclined to the feeding direction of the feeding conveyor belt 33 so that the workpieces 9 on the feeding conveyor belt 33 are arranged in a "Z" shape. In this way, by guiding the workpieces 9 on the feeding conveyor belt 33 to be transported in a "Z" shape by the guide plates 332, the conveying trajectory of the workpieces 9 on the feeding conveyor belt 33 can be extended, thereby enabling the feeding conveyor belt 33 to transport more workpieces 9 at the same time, indirectly saving the space occupied by the feeding conveyor belt 33.

[0059] See Figure 1 and Figure 2As shown, based on the above embodiment of the feeding conveyor belt 33, a return plate 333 is provided on one side of the feeding conveyor belt 33. The return plate 333 is located at the front end of the conveying channel 331 and extends downward at an angle from the feeding conveyor belt 33. The lower end of the return plate 333 is connected to the hopper 31. Thus, since the lifting conveyor chain 32 will simultaneously lift multiple workpieces 9 onto the feeding conveyor belt 33, a large number of workpieces 9 may be stacked at the front end of the conveying channel 331, affecting the workpieces 9 passing through the conveying channel 331 one by one, and thus affecting the feeding speed of the feeding device 3. The return plate 333 can return the excess workpieces 9 at the front end of the conveying channel 331 into the hopper 31, avoiding excessive workpieces 9 at the front end of the conveying channel 331 from affecting the feeding speed of the feeding device 3.

[0060] See Figure 1 As shown, based on the above embodiment of the feeding conveyor belt 33, the feeding device 3 further includes a material guide plate 35 and a material guide plate drive 36. The material guide plate 35 is located above the junction of the feeding conveyor belt 33 and the indexing turntable 2. Multiple toothed grooves 351 are distributed in a ring-shaped pattern on the outer periphery of the material guide plate 35. The material guide plate drive 36 is mounted on the frame 1 by screwing or welding and is connected to the material guide plate 35 in a driving connection. The material guide plate drive 36 drives the material guide plate 35 to rotate toward the indexing turntable 2, thereby moving the workpieces 9 on the feeding conveyor belt 33 toward the indexing turntable 2. Thus, the material guide plate drive 36 drives the material guide plate 35 to rotate, which assists the feeding conveyor belt 33 in conveying the workpieces 9 one by one onto the indexing turntable 2. The material guide plate 35 contacts the workpieces 9 through its outer peripheral surface, and the design of the toothed grooves 351 increases the friction between the material guide plate 35 and the workpieces 9, facilitating the movement of the workpieces 9 toward the indexing turntable 2 by the material guide plate 35.

[0061] The aforementioned feed plate drive 36 can use existing rotary cylinders or rotary motors and other rotary drive mechanisms, and its output end is connected to the feed plate 35 by means of screwing or welding.

[0062] See Figure 1 and Figure 3 As shown, Figure 3The diagram illustrates the structure of the indexing turntable, vision inspection device, and unloading device in this embodiment. Based on any of the above embodiments, the final assembly disc inspection machine also includes a limiting frame 6. The limiting frame 6 is located above the indexing turntable 2 and upstream of the vision inspection device 4. The limiting frame 6 has a limiting channel 61 for limiting the position of the workpiece 9 on the indexing turntable 2. The diameter of the limiting channel 61 gradually decreases along the rotation direction of the indexing turntable 2. Thus, after the feeding conveyor belt 33 transports the workpiece 9 onto the indexing turntable 2, the indexing turntable 2 rotates, causing the workpiece 9 to pass through the limiting channel 61, thereby adjusting the position of the workpiece 9. After the workpiece 9 is positioned, inspection is performed, which improves the consistency and accuracy of the inspection results and prevents the workpiece 9 from deviating from the ideal inspection position. Furthermore, the gradually decreasing diameter of the limiting channel 61 along the rotation direction of the indexing turntable 2 facilitates the smooth entry of the workpiece 9 into the limiting channel 61.

[0063] An infrared sensor or other sensing element 7 can also be installed between the aforementioned limiting frame 6 and the vision inspection device 4 to sense whether a workpiece 9 has moved toward the vision inspection device 4. Once sensed, the vision inspection device 4 is activated to perform the inspection, which can effectively save energy.

[0064] See Figure 1 and Figure 3As shown, in one embodiment of the feeding device 5, the feeding device 5 includes an air blowing mechanism 51, feeding channels 52, a return conveyor belt 53, and a guide plate 54. There are two feeding channels 52, spaced apart on the outer side of the indexing turntable 2. The air blowing mechanism 51 includes two air blowing pipes 511. The air blowing pipes 511 are located above the indexing turntable 2, and the air outlets of the two air blowing pipes 511 face the two feeding channels 52 respectively. The air blowing mechanism 51 is used to blow qualified and unqualified workpieces 9 from the indexing turntable 2 into the two feeding channels 52 respectively. The return conveyor belt 53 is located between the indexing turntable 2 and the loading device 3, and downstream of the two feeding channels 52. The return conveyor belt 53 is used to transport workpieces 9 with disputed inspection results to the loading device 3. The guide plate 54 is located above the indexing turntable 2 and extends towards the return conveyor belt 53. The guide plate 54 is used to guide the workpiece 9 on the indexing turntable 2 to move onto the return conveyor belt 53. Thus, during unloading, the upstream unloading channel 52 is set to transport the workpiece 9 that has passed inspection, and the downstream unloading channel 52 is used to transport the workpiece 9 that has failed inspection. After the workpiece 9 is inspected, the indexing turntable 2 rotates, moving the workpiece 9 to a position opposite to the upstream unloading channel 52. If the workpiece 9 passes inspection, the corresponding air blowing mechanism 51 blows the workpiece 9 into the upstream unloading channel 52. Otherwise, the indexing turntable 2 rotates again, moving the workpiece 9 to a position opposite to the downstream unloading channel 52. If the workpiece 9 fails inspection, the corresponding air blowing mechanism 51 blows the workpiece 9 into the downstream unloading channel 52. If there is any discrepancy in the inspection result of the workpiece 9, the indexing turntable 2 rotates again, causing the workpiece 9 to contact the guide plate 54 and move along the guide plate 54 onto the return conveyor belt 53. It can be seen that the assembly disc inspection machine can classify workpieces 9 into three categories based on the inspection results. It can not only classify and unload workpieces 9 that have passed the inspection and those that have failed the inspection, but also handle workpieces 9 with disputed inspection results and return them to the feeding device 3 so that the feeding device 3 can transport them to the indexing turntable 2 for re-inspection, thereby further improving the accuracy of the inspection results.

[0065] See Figure 1 As shown, a container 8 can be placed at the discharge end of each of the two feeding channels 52, which are used to hold qualified workpieces 9 and unqualified workpieces 9 respectively, so as to facilitate the subsequent unified processing by the staff.

[0066] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
