Description

Technical Field

[0001] This utility model relates to the field of workpiece sorting equipment technology, specifically to a workpiece conveying and sorting device. Background Technology

[0002] In industries such as machining and electronics manufacturing, workpiece conveying and sorting are crucial links in the production process, directly affecting production efficiency, product qualification rate, and the smoothness of subsequent processes. Currently, workpiece conveying and sorting devices on the market are mainly divided into two categories: semi-automatic and fully automatic.

[0003] Semi-automatic equipment typically requires manual assistance for workpiece inspection, sorting, and switching operations. This is not only labor-intensive and costly, but also prone to human error leading to the mixing of qualified and unqualified products, making it difficult to guarantee sorting accuracy and resulting in low efficiency, making it unsuitable for high-speed mass production. While fully automatic equipment can reduce manual intervention, existing structures still have several shortcomings: First, the sorting mechanism has poor motion guidance; the action of switching the sorting table to cover / expose the material drop hole is prone to jamming and deviation, resulting in delayed sorting response and affecting sorting efficiency. Second, the material transfer device is mostly driven in one direction or has a loose three-dimensional motion structure, resulting in low positioning accuracy when gripping workpieces, easily leading to problems such as workpiece falling and misplacement. Moreover, its load-bearing capacity is limited, and structural deformation during high-speed operation can easily cause a decrease in motion accuracy. Third, the coordination between various components is poor; the signal interaction and action connection between the inspection device, material transfer device, and sorting mechanism are not smooth, easily causing process breaks and poor overall operational stability.

[0004] Therefore, there is an urgent need for a workpiece conveying and sorting device that is compact in structure, precise in guidance, and has smooth coordination among its components, while also taking into account both sorting accuracy and operational efficiency, in order to address the shortcomings of existing technologies.

Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0030] The workpiece conveying and sorting device provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0031] Example 1

[0032] This application provides a workpiece conveying and sorting device, including a detection device 1, a loading platform 2, a transfer device 3, a detection platform 4, a sorting platform 5, a moving component 6, a finished product unloading trough 7, and a defective product unloading trough 8. The detection platform 4 and the sorting platform 5 are sequentially arranged on the loading platform 2. The loading platform 2 has a discharge hole corresponding to the sorting platform 5. The defective product unloading trough 8 is located below the discharge hole, and the finished product unloading trough 7 is located outside the sorting platform 5. The detection device 1 is used to detect whether the workpieces on the detection platform 4 are qualified. The transfer device 3 is used to drive the workpieces to move sequentially from the detection platform 4 to the sorting platform 5, and then to the finished product unloading trough 7. The moving component 6 is used to control the sorting platform 5 to block or expose the discharge hole, so that the sorting platform 5 only receives qualified products, and unqualified products fall into the defective product unloading trough 8 through the discharge hole.

[0033] like Figures 1 to 5 As shown, due to the above structure, firstly, the external feeding mechanism transports the workpiece to the inspection table 4. The inspection device 1 starts and performs quality inspection on the workpiece on the inspection table 4, generating a qualified or unqualified inspection signal. Next, the transfer device 3 receives the inspection signal and starts, driving the workpiece from the inspection table 4 to above the sorting table 5. If the inspection signal is qualified, the moving component 6 first receives the signal and drives the sorting table 5 to move to the position that blocks the discharge hole. The workpiece falls onto the sorting table 5, and then the transfer device 3 continues to drive the workpiece along the sorting table 5 to the finished product discharge trough 7, completing the unloading of qualified products. If the inspection signal is unqualified, the moving component 6 receives the signal and drives the sorting table 5 to move to the position that exposes the discharge hole. The workpiece falls directly from above the sorting table 5 through the discharge hole into the defective product discharge trough 8 below, realizing the unqualified product unloading. Through the signal interaction and action coordination of the detection device 1, the transfer device 3 and the moving component 6, the automated detection, conveying and sorting of workpieces can be integrated, effectively avoiding the mixing of qualified and unqualified products, significantly improving the accuracy and automation of workpiece sorting, and reducing the labor intensity and error rate of manual sorting.

[0034] Example 2

[0035] In this embodiment, in addition to the structural features of the aforementioned embodiments, a connecting frame 9 is also included, which is fixed on the loading platform 2. A limiting groove 91 is provided on the connecting frame 9, and a limiting slider 92 that slides in cooperation with the limiting groove 91 is fixed on the sorting platform 5. The cross-sections of the limiting groove 91 and the limiting slider 92 are both T-shaped.

[0036] In this embodiment of the application, a mounting frame 10 is also fixed on the loading platform 2; the mounting frame 10 extends along the length direction of the limiting slide groove 91 to the side away from the discharge hole, the moving component 6 is a cylinder, the cylinder is fixed at the outer end of the mounting frame 10, and the piston rod is connected to the sorting table 5.

[0037] like Figures 1 to 3As shown, due to the above structure, when the detection device 1 generates a qualified detection signal, the cylinder receives the signal and drives the piston rod to extend. The piston rod pushes the sorting table 5 to slide along the limiting slide groove 91 on the connecting frame 9. At this time, the T-shaped limiting slider 92 on the sorting table 5 slides synchronously in the T-shaped limiting slide groove 91 until the sorting table 5 completely blocks the material drop hole on the loading platform 2, and the workpiece falls onto the sorting table 5 to complete the receiving. When the detection device 1 generates a failed detection signal, the cylinder receives the signal and drives the piston rod to retract. The piston rod pulls the sorting table 5 to slide in the opposite direction along the limiting slide groove 91. The T-shaped limiting slider 92 slides synchronously with the sorting table 5 until the sorting table 5 is completely exposed from the material drop hole, and the workpiece falls into the defective product discharge trough 8 through the material drop hole. The sliding cooperation between the T-shaped limiting slide 91 and the T-shaped limiting slider 92 not only provides precise guidance for the movement of the sorting table 5, but also effectively prevents the sorting table 5 from detaching from the connecting frame 9 during the sliding process through the upper and lower limiting effect of the T-shaped structure. At the same time, the mounting frame 10 provides a stable mounting base for the cylinder. The extension and retraction of the cylinder directly drives the movement of the sorting table 5. It has a fast response speed and high control precision. It can quickly switch the state of the sorting table 5 covering or exposing the material drop hole, further improving the efficiency of workpiece sorting and adapting to the use requirements of high-speed production lines.

[0038] Example 3

[0039] In this embodiment, in addition to the structural features of the aforementioned embodiments, the material transfer device 3 includes a mounting plate 31, a plurality of grippers 32, a lifting frame 33, a longitudinal moving frame 34, a transverse moving plate 35, a mounting platform 36, and a plurality of linear drive components 37; each of the linear drive components 37 is used to drive the lifting frame 33 to move up and down relative to the longitudinal moving frame 34, the longitudinal moving frame 34 to move longitudinally relative to the transverse moving plate 35, and the transverse moving plate 35 to move laterally relative to the mounting platform 36; the mounting plate 31 is fixed on the lifting frame 33, and each gripper 32 is arranged at intervals along a straight line on the mounting plate 31.

[0040] In this embodiment of the application, the linear drive assembly 37 includes a plurality of slide rail pairs 371 and a plurality of linear actuators 372. Each slide rail pair 371 is respectively disposed between the lifting frame 33 and the longitudinal frame 34, between the longitudinal frame 34 and the transverse plate 35, and between the transverse plate 35 and the mounting platform 36. Each linear actuator 372 is used to drive the lifting frame 33, the longitudinal frame 34 and the transverse plate 35 to move along the corresponding slide rail pair 371.

[0041] In this embodiment of the application, a plurality of reinforcing plates 38 are connected between the mounting plate 31 and the lifting frame 33.

[0042] In this embodiment of the application, a support truss 39 is also included, the top of which is slidably engaged with the end of the transverse plate 35 away from the mounting platform 36 via a slide rail pair 371.

[0043] like Figures 1 to 5As shown, due to the above structure, when a workpiece needs to be gripped on the inspection table 4, the linear drive assembly 37 that drives the transverse plate 35 to move relative to the mounting table 36 is activated, and the linear actuator 372 drives the transverse plate 35 to move along the corresponding slide rail pair 371 until the gripper 32 moves above the inspection table 4; then, the linear drive assembly 37 that drives the longitudinal frame 34 to move relative to the transverse plate 35 is activated, and the linear actuator 372 drives the longitudinal frame 34 to move along the corresponding slide rail pair 371, realizing the longitudinal positioning of the gripper 32; finally, the linear drive assembly 37 that drives the lifting frame 33 to move relative to the longitudinal frame 34 is activated, and the linear actuator 372 drives the lifting frame 33 to descend along the corresponding slide rail pair 371, and the mounting plate 31 descends synchronously with the lifting frame 33 until the gripper 32 grips the workpiece. After the workpiece is gripped, each linear drive component 37 reverses its direction, driving the lifting frame 33 to rise and the longitudinal transfer frame 34 and transverse transfer plate 35 to reset, transporting the workpiece above the sorting table 5. The positioning action is then repeated to place the workpiece in the sorting table 5 or the finished product unloading trough 7. Each gripper 32 is arranged at a linear interval on the mounting plate 31, allowing for the simultaneous gripping of multiple workpieces and significantly improving workpiece conveying efficiency. The reinforcing plate 38 between the mounting plate 31 and the lifting frame 33 enhances the connection strength, preventing deformation of the mounting plate 31 when the grippers 32 grip the workpiece. The supporting truss 39 slides with the end of the transverse transfer plate 35 away from the mounting table 36 via a slide rail pair 371, sliding synchronously with the transverse transfer plate 35 as it moves, providing auxiliary support and effectively preventing bending deformation of the transverse transfer plate 35 due to its own weight or excessive load. This ensures precise movement of the transfer device 3 in three-dimensional space, improving the accuracy and stability of workpiece conveying.

[0044] Example 4

[0045] In this embodiment, in addition to the structural features of the aforementioned embodiments, the linear actuator 372 is a cylinder, the body of which is mounted on the longitudinal frame 34, the transverse plate 35 or the mounting platform 36, and the outer end of the piston rod of the cylinder is connected to the lifting frame 33, the longitudinal frame 34 or the transverse plate 35.

[0046] In this embodiment of the application, the longitudinal moving frame 34 includes a base plate 341, a pair of side plates 342 and a pair of crossbeams 343. The base plate 341 is connected to the bottom of the pair of side plates 342, and the pair of crossbeams 343 are connected to the top of the pair of side plates 342. A through hole 344 is also provided on the base plate 341. A cylinder for driving the lifting frame 33 to rise and fall is installed at the bottom of the base plate 341, and the piston rod passes through the through hole 344 to connect to the lifting frame 33.

[0047] In this embodiment of the application, a pair of guide plates 345 and a pair of guide rods 346 are also included; the pair of guide plates 345 are symmetrically fixed on the inner side wall of the lifting frame 33 relative to the longitudinal moving frame 34, and each guide plate 345 is provided with a guide hole in the longitudinal direction; the pair of guide rods 346 are symmetrically fixed on the base plate 341 and slide through the corresponding guide hole.

[0048] like Figures 1 to 5 As shown, due to the above structure, the cylinder body that drives the lifting frame 33 to rise and fall is installed at the bottom of the base plate 341 of the longitudinal frame 34. The piston rod passes through the through hole 344 on the base plate 341 and connects to the lifting frame 33. When the cylinder is started, the piston rod extends and retracts to drive the lifting frame 33 to rise and fall. At this time, the guide plate 345 on the inner side wall of the lifting frame 33 moves synchronously with the lifting frame 33. The guide hole on the guide plate 345 slides along the guide rod 346 on the base plate 341, providing precise guidance for the lifting movement of the lifting frame 33 and effectively preventing the lifting frame 33 from tilting or jamming during the lifting process. The cylinder body that drives the longitudinal movement of the longitudinal frame 34 is mounted on the transverse plate 35. The piston rod is connected to the side plate 342 of the longitudinal frame 34. When the cylinder is started, it drives the longitudinal frame 34 to move longitudinally along the slide rail pair 371 on the transverse plate 35. The cylinder body that drives the transverse plate 35 to move laterally is mounted on the mounting platform 36. The piston rod is connected to the transverse plate 35. When the cylinder is started, it drives the transverse plate 35 to move laterally along the slide rail pair 371 on the mounting platform 36. The coordinated action of cylinders in three directions enables the three-dimensional movement of the transfer device 3. The cylinders have a fast response speed and low cost, meeting the high-speed movement requirements of the transfer device 3. The base plate 341, side plate 342 and crossbeam 343 of the longitudinal transfer frame 34 form a frame structure with high structural strength, providing a stable installation foundation for the cylinders and guide rods 346. The cooperation between the guide rods 346 and the guide plate 345 further improves the stability and accuracy of the movement of the lifting frame 33, ensuring that the grippers 32 can accurately grasp and place the workpieces, thereby ensuring the efficient and stable operation of the entire workpiece conveying and sorting device.
