[0021] In the field of workpiece manufacturing and processing, some workpieces require baking to optimize their physical or chemical properties and meet subsequent usage standards. After baking, the workpieces must undergo quality inspection to remove defective products, ensuring the quality of the final product. Therefore, workpiece baking quality inspection equipment integrating workpiece transfer, baking, inspection, and receiving functions has become a key piece of equipment in related production processes. Existing workpiece baking quality inspection equipment suffers from problems of inefficient functional integration and incomplete inspection, resulting in low overall operating efficiency and an inability to meet the needs of large-scale production.

[0022] Based on this, this application provides a workpiece baking quality inspection device to solve the above-mentioned technical problems. The technical solutions provided by this application will be described in detail below.

[0023] Reference Figure 1 This application provides a workpiece baking quality inspection device, including: a conveying device 100, a feeding device 200, a baking device 300, a first detection device 400, a flipping device 500, a second detection device 600, and a receiving device 700. The conveying device 100 is used to transport workpieces according to a preset conveying path; the feeding device 200 is disposed on the side of the first end of the conveying device 100 and is used to provide workpieces to be baked; the baking device 300 is disposed on the rear side of the feeding device 200 relative to the conveying path and is used to bake the workpieces; the first detection device 400 is disposed on the side of the baking device 300 relative to the conveying path. The first detection device 400 is located behind the first detection device 400 relative to the transmission path and is used to flip the workpiece on the transmission device 100. The second detection device 600 is located behind the first detection device 400 relative to the transmission path and is used to detect the back of the workpiece. The receiving device 700 is located at the end of the transmission device 100 and includes a tray-sinking mechanism 710 and a tray-feeding mechanism 720. The tray-feeding mechanism 720 is used to provide an empty tray 724, and the tray-sinking mechanism 710 is used to grab the workpiece at the end of the transmission device 100 and transfer it to the tray 724.

[0024] This workpiece baking and quality inspection equipment uses a conveyor device 100 as its core transport base. Following a preset transport path, it sequentially connects a feeding device 200, a baking device 300, a first inspection device 400, a flipping device 500, a second inspection device 600, and a receiving device 700. The receiving device 700 specifically includes a tray feeding mechanism 720 and a tray placement mechanism 710, forming a complete operational structure from workpiece feeding and baking to front and back inspection, and then to automatic tray feeding and tray placement for receiving. This structure achieves seamless connection between each stage through the conveyor device 100. Furthermore, with the help of the flipping device 500 in conjunction with the first inspection device 400 and the second inspection device 600, the front and back of the workpiece can be inspected separately, solving the problem of incomplete single-inspection. Simultaneously, the tray feeding mechanism 720 automatically provides the loading tray 724, and the tray placement mechanism 710 automatically picks up and places the workpiece on the tray, eliminating the reliance on manual handling for receiving. Ultimately, this achieves continuous equipment operation, comprehensive quality inspection, and automated receiving, effectively improving overall operational efficiency and ensuring workpiece quality inspection.

[0025] Reference Figure 2 It is understood that the feeding device 200 includes a feeding conveyor belt 210, a feeding sensor 220, a positioning cylinder 230, and a guide baffle 240. The feeding conveyor belt 210 is located on the side of the first end of the transmission device 100. The feeding sensor 220, the positioning cylinder 230, and the guide baffle 240 are sequentially arranged on the feeding conveyor belt 210. The feeding sensor 220 is used to sense the feeding signal of the workpiece to be baked. The positioning cylinder 230 is used to push the corresponding workpiece to move toward the first side of the feeding conveyor belt 210 according to the feeding signal. The guide baffle 240 is used to guide the workpiece to approach the first side of the feeding conveyor belt 210. The feeding sensor 220 can capture the feeding signal of the workpiece to be baked in real time, providing a precise trigger basis for the action of the positioning cylinder 230, avoiding blind operation of the cylinder. The positioning cylinder 230 works in conjunction with the guide baffle 240. The former actively pushes the workpiece to the first side of the feeding conveyor belt 210 according to the signal, while the latter guides the workpiece to approach that side from the side. The two work together to ensure that each workpiece is stably in the preset position during feeding, preventing workpiece deviation or misalignment, thereby ensuring that the position of the workpieces entering the subsequent transmission device 100 and baking device 300 is uniform, laying the foundation for the uniformity of subsequent baking and the accuracy of detection, and reducing process problems caused by feeding positioning deviation.

[0026] Reference Figure 1 and Figure 2It is understandable that a first transfer mechanism 800 is provided between the beginning ends of the feeding device 200 and the conveying device 100. The first transfer mechanism 800 is used to transfer the workpiece from the feeding device 200 to the conveying device 100. The first transfer mechanism 800, located between the beginning ends of the feeding device 200 and the conveying device 100, solves the connection problem during the transfer of workpieces from the feeding device 200 to the conveying device 100, achieving a precise and automated transition between the two. The first transfer mechanism 800 can directly grab the workpiece that has been positioned at the feeding device 200 and smoothly transfer it to the conveying device 100 according to a preset position. This avoids positional shifts and drops that are prone to occur when workpieces rely on themselves or are transferred manually, ensuring a uniform initial position for the workpieces when they enter the conveying device 100. Simultaneously, it reduces the labor intensity of manual operation and avoids efficiency fluctuations caused by manual transfer, further improving the continuity and operational efficiency of the entire equipment from workpiece feeding to transfer.

[0027] Reference Figure 2 It is understood that the first material transfer mechanism 800 includes a support base 810, a first transfer module 820, a second transfer module 830, and a first suction structure 840. The support base 810 is mounted on the support frame of the feeding device 200 and the transmission device 100. The first transfer module 820 is mounted on the support base 810, and its drive end is connected to the second transfer module 830. The drive direction of the first transfer module 820 corresponds to the transmission path. The drive end of the second transfer module 830 is connected to the first suction structure 840, which drives the first suction structure 840 to move vertically. The first suction structure 840 is used to pick up workpieces from the feeding device 200 and place the workpieces on the transmission device 100. The support base 810 provides a stable mounting foundation for the entire mechanism, preventing positional deviations caused by mechanism swaying during the material transfer process. The first transfer module 820, driven in a direction corresponding to the transmission path, can move the second transfer module 830 and the first suction structure 840 horizontally along the direction of the matching transmission device 100, ensuring that the horizontal trajectory of the workpiece transfer is precisely aligned with the workpiece receiving position of the transmission device 100, preventing horizontal misalignment. The second transfer module 830 can drive the first suction structure 840 to move flexibly in the vertical direction, facilitating the first suction structure 840 to approach the loading device 200 downwards to pick up the workpiece, and adjusting the height of the workpiece when lowering it according to the height of the transmission device 100, making the picking and placing actions more flexible and adaptable. With the coordinated action of all components, the transfer of the workpiece from the loading device 200 to the transmission device 100 achieves precise positioning, smooth operation, and non-destructive operation, effectively connecting the loading and transmission processes, and providing a reliable guarantee for the stable operation of subsequent baking, inspection, and other processes.

[0028] Reference Figure 1 and Figure 3It is understood that a second transfer mechanism 910 is provided between the baking device 300 and the first detection device 400 to remove the baked workpiece from the baking device 300. A third transfer mechanism 920 is also provided between the first detection device 400 and the flipping device 500 to pick up the workpiece and place it onto the flipping device 500. The second transfer mechanism 910 enables a smooth and precise transfer of the baked workpiece from the baking device 300 to the first detection device 400, avoiding problems such as positional shifts or damage caused by manual transfer or lack of a dedicated transfer mechanism after baking, and ensuring that the workpiece enters the first detection device 400 in a stable state. The third transfer mechanism 920 can accurately pick up the workpiece that has completed front-side inspection and transfer it to the flipping device 500, avoiding positioning deviations of the workpiece when transferring it from the inspection stage to the flipping stage, ensuring that the workpiece is in the preset flipping position on the flipping device 500, and preventing incomplete flipping or positional shifts after flipping due to workpiece misplacement.

[0029] It should be noted that the specific structures of the second transfer mechanism 910 and the third transfer mechanism 920 are similar to those of the first transfer mechanism 800. For details, please refer to the relevant embodiments corresponding to the first transfer mechanism 800.

[0030] Reference Figure 3 It is understood that the flipping device 500 includes a rotary motor 510, a connecting plate 520, and a second suction structure 530. The rotary motor 510 is located on the side of the transmission device 100 and on the rear side of the third transfer mechanism 920 relative to the transmission path. One end of the connecting plate 520 is connected to the drive end of the rotary motor 510. The second suction structure 530 is located at the other end of the connecting plate 520. When the other end of the connecting plate 520 is close to the third transfer mechanism 920, the third transfer mechanism 920 is used to place the workpiece on the upper surface of the connecting plate 520 so that the second suction structure 530 sucks the back of the workpiece. The rotary motor 510 is used to flip the connecting plate 520 so that the back of the workpiece faces upward. The rotary motor 510 is located beside the conveying device 100 and behind the third transfer mechanism 920, allowing for smooth process connection with the third transfer mechanism 920. One end of the connecting plate 520 is connected to the rotary motor 510, and the other end is fitted with the second suction structure 530. This provides a stable platform for the workpiece and, through the second suction structure 530, firmly holds the back of the workpiece when it is placed by the third transfer mechanism 920, preventing it from slipping or shifting during the flipping process. The rotary motor 510 drives the connecting plate 520 to flip the workpiece so that its back faces upwards, accurately meeting the inspection requirements of the subsequent second inspection device 600 for the back of the workpiece. This ensures that the position of the flipped workpiece meets the inspection standards, avoiding any impact on inspection accuracy due to flipping deviation. Furthermore, the entire flipping process is automated through a mechanical structure, requiring no manual intervention, further improving the smoothness of process connection and overall work efficiency, while also reducing potential damage to the workpiece caused by manual operation.

[0031] Continue to refer to Figure 3 It is understood that the first detection device 400 includes a mounting post 410, a first adjusting block 420, a second adjusting block 430, a magnifying module 440, and an image acquisition module 450. The first adjusting block 420 and the second adjusting block 430 are movably mounted on the mounting post 410, with the first adjusting block 420 located above the second adjusting block 430. The image acquisition module 450 is mounted on the first adjusting block 420, and the magnifying module 440 is mounted on the second adjusting block 430. The image acquisition module 450 is used to acquire frontal image information of the workpiece through the magnifying module 440. Since the first adjusting block 420 carries the image acquisition module 450 and the second adjusting block 430 carries the magnification module 440, and both can move along the mounting column 410, the focusing position of the magnification module 440 and the shooting height of the image acquisition module 450 can be precisely adjusted according to the specifications of the workpiece to be inspected. This ensures that the acquisition module can clearly capture the subtle features of the front of the workpiece through the magnification module 440, avoiding problems such as image blurring and missed key details caused by differences in workpiece specifications under fixed position settings, and providing a clear image basis for accurately identifying defects on the front of the workpiece.

[0032] Reference Figure 4 It is understood that the tray-loading mechanism 710 includes a third transfer module 711, a fourth transfer module 712, a lifting module 713, and a third suction structure 714. The third transfer module 711 is located at the end of the transmission device 100, and its driving end is connected to the fourth transfer module 712. The driving end of the fourth transfer module 712 is connected to the lifting module 713. The driving end of the lifting module 713 is connected to the third suction structure 714. The driving directions of the third transfer module 711, the fourth transfer module 712, and the lifting module 713 are perpendicular to each other. The third suction structure 714 is used to pick up the workpiece at the end of the transmission device 100 and place the workpiece on the loading tray 724 of the tray-feeding mechanism 720. The driving directions of the third transfer module 711, the fourth transfer module 712, and the lifting module 713 are perpendicular to each other, which can drive the third suction structure 714 to freely adjust its position in the horizontal and vertical three-dimensional space. It can accurately align with the workpiece at the end of the transmission device 100 to complete the gripping, and can flexibly adjust the horizontal coordinates and vertical height of the workpiece according to the grid distribution and placement height of the loading tray 724 on the feeding mechanism 720, so as to avoid the problem of misalignment of the loading tray or inability to adapt to different specifications of loading tray 724 due to fixed position.

[0033] Continue to refer to Figure 4It is understandable that the third suction structure 714 includes several suction cups. Several suction cups can pick up multiple workpieces at the same time, eliminating the need to frequently move back and forth between the end of the transmission device 100 and the loading tray 724 after grabbing a single workpiece. This saves time wasted on back-and-forth movement, making the tray placement action more continuous and efficient. While ensuring the integrity of the workpiece and the accuracy of the tray placement, it improves the overall operational efficiency of the receiving process.

[0034] Continue to refer to Figure 4 It is understood that the tray feeding mechanism 720 includes a tray transfer drive module 721, at least one first tray holder 722, and at least one second tray holder 723. The first tray holder 722 is used to place empty trays 724, and the second tray holder 723 is used to place full trays 724. The tray transfer drive module 721 is used to move the trays 724 filled with workpieces from the first tray holder 722 to the second tray holder 723. The tray transfer drive module 721 can automatically move the trays 724 filled with workpieces from the first tray holder 722 to the second tray holder 723 without manual intervention, which reduces the intensity of manual labor and avoids problems such as tilting of the trays 724, dropping of workpieces, or damage from impacts that may occur during manual transfer. Meanwhile, the automated pallet transfer can quickly free up space in the first pallet rack 722 to receive new empty pallets 724, ensuring that the workpiece placement action of the palletizing mechanism 710 is uninterrupted, effectively connecting the palletizing and pallet transfer process, and further improving the continuity of the receiving process and the overall operational efficiency.

[0035] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
