Description

Technical Field

[0001] This application relates to the field of processing and testing technology, specifically to a testing device. Background Technology

[0002] In the manufacturing process of electronic products, inspecting the flatness of workpieces is a critical quality control step. Currently, the common inspection method usually relies on manual operation, where operators manually place each workpiece to be tested onto the measuring station of the detector before starting the equipment for inspection. This manual operation mode has many drawbacks: First, it is labor-intensive for operators and has low inspection efficiency, making it difficult to meet the needs of large-scale mass production; second, during manual placement, the workpiece is prone to tilting due to inaccurate positioning or poor placement posture, causing the actual measured plane to be non-parallel to the theoretical reference plane of the detector, thus introducing measurement errors and seriously affecting the accuracy and reliability of the inspection results. Utility Model Content

[0003] In view of the above, it is necessary to propose a detection device that automatically provides workpieces through a feeding mechanism, places the workpieces to be detected on the detection platform of the detection mechanism through a transfer mechanism, and then the detection component detects the workpieces. After the detection is completed, the transfer mechanism places the workpieces into the receiving mechanism, thereby realizing automatic detection. This can at least solve the problems of low efficiency, high labor intensity, and large measurement errors caused by poor placement posture in the prior art due to reliance on manual detection.

[0004] This application provides a testing device, including: a machine base; a feeding mechanism disposed on the machine base, the feeding mechanism carrying a tray loaded with workpieces to be tested; a receiving mechanism disposed on the machine base and close to the feeding mechanism, the receiving mechanism carrying the tray loaded with the tested workpieces; a testing mechanism disposed on the machine base and close to the receiving mechanism on the side away from the feeding mechanism, the testing mechanism including a testing platform disposed close to the receiving mechanism and a testing component disposed close to the testing platform; and a transfer mechanism disposed close to the machine base; wherein, the transfer mechanism transfers the workpieces to be tested from the feeding mechanism to the testing platform so that the testing component can test the workpieces, and the transfer mechanism also transfers the tested workpieces to the receiving mechanism for receiving.

The detection drive is disposed close to the detection platform, and the detection drive drives the bracket to move so that the detector moves along the extension direction of the detection platform, so that the detector passes over the detection platform and detects the workpiece located on the detection platform.

[0006] In some embodiments, the detection mechanism further includes a rejection gripper connected to the bracket, and the detection drive unit drives the rejection gripper to move along the extension direction of the detection platform through the bracket, so that the rejection gripper removes the defective workpiece located on the detection platform from the detection platform.

[0007] In some embodiments, the inspection mechanism further includes a waste bin connected to the machine tool and disposed near the inspection platform, the waste bin being configured to collect defective workpieces.

[0008] In some embodiments, the detection platform has a plurality of positioning slots on the side away from the machine tool, each of the plurality of positioning slots being configured to accommodate the workpiece, and the bottom of each positioning slot being horizontally set.

[0009] In some embodiments, the machine tool has a discharge port disposed opposite to the feeding mechanism; the feeding mechanism includes a feeding assembly connected to the machine tool and located below the discharge port, the feeding assembly includes a feeding drive unit disposed below the discharge port and a carrier plate connected to the feeding drive unit, the carrier plate carries a plurality of stacked trays, and the feeding drive unit drives the carrier plate to approach the discharge port so as to move the trays to the discharge port.

[0010] In some embodiments, the feeding mechanism further includes a plurality of first positioning members connected to the side of the machine base away from the feeding assembly, the plurality of first positioning members being arranged around the discharge port and abutting against the periphery of the material tray to position the material tray.

[0013] The aforementioned inspection device uses a feeding mechanism to carry a tray containing workpieces to be inspected, a transferring mechanism to place the workpieces onto the inspection platform, and an inspection component to inspect the workpieces on the platform. After inspection, the transferring mechanism places the inspected workpieces onto a receiving mechanism, thus achieving automated inspection.

[0014] The aforementioned inspection device, through an automatic material transfer mechanism between the feeding mechanism, inspection platform, and receiving mechanism, achieves a complete automated cycle of workpiece loading, positioning, inspection, and unloading.

The inspection platform provides a stable and highly repeatable positioning reference for the workpiece, ensuring that the relative positional relationship between the measured plane of the workpiece and the inspection components remains consistent during each inspection. This eliminates human-introduced measurement errors, resulting in accurate, reliable, and highly consistent inspection data. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0022] The following will describe some embodiments of this application in detail with reference to the accompanying drawings.

[0023] Please see Figure 1 , Figure 2 and Figure 3This application provides a detection device 100 for detecting workpiece 300. In this embodiment, the detection device 100 is used to detect the flatness and thickness of the workpiece 300. The detection device 100 includes a machine base 10, a feeding mechanism 20, a receiving mechanism 30 and a detection mechanism 40 disposed on the machine base 10, and a transfer mechanism 50 disposed near the machine base 10.

[0024] In this embodiment, the machine tool 10 has a discharge port 11 opposite to the feeding mechanism 20 and a receiving position 12 adjacent to the discharge port 11. The receiving position 12 is configured to carry a material tray 200. It can be understood that the material tray 200 has a rectangular structure; therefore, in this embodiment, the discharge port 11 is a rectangular structure adapted to the material tray 200. The material tray 200 carried by the receiving position 12 is used to load the inspected workpiece 300.

[0025] In this embodiment, please refer to Figure 1 , Figure 2 and Figure 3 The feeding mechanism 20 is set on the machine base 10, and the feeding mechanism 20 carries a tray 200 loaded with workpieces 300 to be inspected.

[0026] The feeding mechanism 20 includes a feeding component 21 connected to the machine base 10 and located below the discharge port 11, a plurality of first positioning components 22 connected to the side of the machine base 10 away from the feeding component 21, and two positioning components 23 connected to the side of the machine base 10 away from the feeding component 21.

[0027] The loading assembly 21 includes a loading drive 211 disposed below the discharge port 11 and a carrier plate 212 connected to the loading drive 211. The carrier plate 212 carries multiple stacked trays 200. The loading drive 211 drives the carrier plate 212 closer to the discharge port 11, thereby moving the trays 200 above the discharge port 11. The loading drive 211 is a lifting cylinder. The carrier plate 212 can carry ten, twenty, or more stacked trays 200. It can be understood that the trays 200 carried by the carrier plate 212 contain workpieces 300 to be inspected. During loading, the loading drive 211 drives the carrier plate 212 to rise, thereby moving the uppermost tray 200 above the discharge port 11.

[0028] Multiple first positioning elements 22 are arranged around the discharge port 11 and abut against the periphery of the material tray 200 to position the material tray 200. The first positioning elements 22 are plate-shaped structures, and a total of eight first positioning elements 22 are provided, with each pair of first positioning elements 22 positioned opposite one side of the discharge port 11. When the material tray 200 moves above the discharge port 11, the eight first positioning elements 22 are used to restrict the sides of the material tray 200, thereby improving the positional accuracy of the material tray 200.

[0029] Two positioning components 23 are respectively disposed on opposite sides of the discharge port 11. Each positioning component 23 includes a positioning drive 231 connected to the machine base 10 and a pushing member 232 connected to the positioning drive 231. The two positioning drive components 231 drive the corresponding pushing member 232 to approach the material tray 200 to clamp and position the material tray 200. The positioning drive 231 is a telescopic cylinder, and the pushing member 232 is a block structure. When the material tray 200 moves above the discharge port 11, the two positioning drive components 231 respectively drive the two pushing members 232 to move towards each other, thereby clamping and positioning the material tray 200 to further improve the positional accuracy of the material tray 200.

[0030] In this embodiment, please refer to Figure 1 , Figure 2 and Figure 3 The receiving mechanism 30 is disposed on the machine base 10 and close to the feeding mechanism 20. The receiving mechanism 30 carries a tray 200 loaded with inspected workpieces 300. The receiving mechanism 30 includes a plurality of second positioning members 31 connected to the machine base 10. The plurality of second positioning members 31 are disposed around the receiving position 12 and abut against the periphery of the tray 200 to position the tray 200.

[0031] The second positioning element 31 is a plate-shaped structure, and a total of eight second positioning elements 31 are provided. Each pair of second positioning elements 31 are arranged opposite to one side of the receiving position 12. When an empty material tray 200 for receiving is placed in the receiving position 12, the eight second positioning elements 31 are used to limit the side of the material tray 200, thereby improving the positional accuracy of the material tray 200.

[0032] In this embodiment, please refer to Figure 1 and Figure 2 The detection mechanism 40 is set on the machine base 10 and is located on the side of the receiving mechanism 30 away from the feeding mechanism 20. The detection mechanism 40 includes a detection platform 41 located near the receiving mechanism 30, a detection component 42 located near the detection platform 41, a rejection gripper 43 connected to the detection component 42, and a waste box 44 connected to the machine base 10 and located near the detection platform 41.

[0033] The inspection platform 41 has multiple positioning slots 411 on the side opposite to the machine base 10. Each positioning slot 411 is configured to accommodate a workpiece 300, and the bottom of each slot 411 is horizontal. The inspection platform 41 has a flat plate structure. In this embodiment, the positioning slots 411 are arranged in two rows, with twelve slots 411 in each row. This means the inspection platform 41 can simultaneously hold twenty-four workpieces 300, allowing for simultaneous inspection of all twenty-four workpieces 300, effectively improving inspection efficiency. The horizontal bottom of each positioning slot 411, located on the same plane, ensures a consistent inspection reference for each workpiece 300.

[0034] The detection assembly 42 includes a detection drive 421 connected to the machine base 10, a bracket 422 connected to the detection drive 421, and a detector 423 connected to the bracket 422. The detection drive 421 is positioned close to the detection platform 41. The detection drive 421 drives the bracket 422 to move, thereby causing the detector 423 to move along the extension direction of the detection platform 41, so that the detector 423 passes over the detection platform 41, thereby detecting the workpiece 300 located on the detection platform 41. The detection drive 421 is a servo cylinder, the bracket 422 is a rod-shaped structure, and the detector 423 is a distance sensor. In this embodiment, two detectors 423 are provided, corresponding to two rows of positioning slots 411 respectively. During detection, the detection drive 421 drives the bracket 422 to move, thereby causing the detector 423 to pass over each positioning slot 411. When the detector 423 passes over the positioning slot 411, it measures the height of multiple positions of the workpiece 300 contained in the positioning slot 411. If the height of multiple positions is within the preset range, then workpiece 300 is qualified; if some positions of workpiece 300 are not within the preset range, it indicates that the flatness of workpiece 300 is insufficient and some parts of the structure of workpiece 300 are tilted, then workpiece 300 is unqualified; if the height of each position of workpiece 300 exceeds the preset range, it indicates that workpiece 300 is stacked or has multiple parts bonded together, then workpiece 300 is unqualified.

[0035] The detection drive unit 421 drives the rejection gripper 43 to move along the extension direction of the detection platform 41 via the bracket 422, so that the rejection gripper 43 removes the defective workpiece 300 located on the detection platform 41. The rejection gripper 43 is a suction cup type gripper. In this embodiment, the rejection gripper 43 is connected to the bracket 422 via a lifting cylinder. Two rejection grippers 43 are provided, respectively arranged opposite to two rows of positioning slots 411. When the detector 423 detects that the workpiece 300 in a certain positioning slot 411 is defective, the rejection gripper 43 can remove the workpiece 300 from the positioning slot 411 to reject the defective workpiece 300.

[0036] The scrap box 44 is configured to collect defective workpieces 300. After the rejecting gripper 43 removes the defective workpieces 300 from the positioning slot 411, the defective workpieces 300 can be placed in the scrap box 44 for easy collection and sorting. In this embodiment, the scrap box 44 is detachably connected to the machine base 10. When the scrap box 44 is full of defective workpieces 300, the operator can remove the scrap box 44 to collect the defective workpieces 300 and install the empty scrap box 44 on the machine base 10.

[0037] In this embodiment, the material transfer mechanism 50 is located close to the machine base 10. The material transfer mechanism 50 includes a material transfer drive 51 located close to the machine base 10 and a material transfer gripper 52 connected to the material transfer drive 51. The material transfer drive 51 drives the material transfer gripper 52 to move between the material feeding mechanism 20, the material receiving mechanism 30 and the detection platform 41. The material transfer gripper 52 is configured to grip or release the workpiece 300.

[0038] The transfer mechanism 50 transfers the workpiece 300 to be inspected in the feeding mechanism 20 to the inspection platform 41 so that the inspection component 42 can inspect the workpiece 300. The transfer mechanism 50 also transfers the inspected workpiece 300 to the receiving mechanism 30 for receiving.

[0039] The material transfer drive 51 is a robotic arm, and the material transfer gripper 52 is a suction cup gripper. In this embodiment, the material transfer gripper 52 has two rows of suction nozzles, with twelve suction nozzles in each row. In this way, it can simultaneously adsorb twenty-four workpieces 300, thereby improving the efficiency of transferring workpieces 300.

[0040] The detection device 100 provided in this embodiment can carry a tray 200 containing workpieces 300 to be detected via a feeding mechanism 20. A transferring mechanism 50 places the workpieces 300 onto the detection platform 41 of the detection mechanism 40. The detection component 42 then detects the workpieces 300 on the detection platform 41. After detection, the transferring mechanism 50 places the detected workpieces 300 into the receiving mechanism 30, thus achieving automated detection.

[0041] The detection device 100 provided in this embodiment of the application automatically transfers materials between the feeding mechanism 20, the detection platform 41, and the receiving mechanism 30 via the material transfer mechanism 50. This achieves a complete automated cycle of loading, positioning, detection, and unloading of workpieces 300, replacing the tedious steps of manually placing, starting, and removing workpieces 300 one by one in traditional operations. The detection cycle time depends solely on the equipment's operating speed, thereby increasing the detection throughput per unit time and adapting to the production cycle requirements of large-scale batch production. The entire detection process is completed automatically by the equipment, avoiding workpiece 300 placement posture problems caused by operator fatigue, differences in skill level, or negligence. The detection platform 41 provides a stable and highly repeatable positioning reference for the workpiece 300, ensuring that the relative positional relationship between the measured plane of the workpiece 300 and the detection component 42 remains consistent during each detection. This eliminates human-introduced measurement errors, resulting in accurate, reliable, and highly consistent detection data.

[0042] The working process of the detection device 100 provided in this embodiment is roughly as follows: First, multiple stacked trays 200, each carrying a workpiece 300 to be inspected, are placed on a carrier plate 212. The loading drive 211 drives the carrier plate 212 upwards until the uppermost tray 200 passes through the discharge port 11. At this point, multiple first positioning members 22 perform initial positioning of the tray 200. Then, the positioning drive 231 drives the pushing members 232 to hold the tray 200, thereby clamping and positioning the tray 200. This allows for precise positioning of the tray 200, improving the accuracy of material handling.

[0043] Then, the transfer drive 51 drives the transfer gripper 52 to move so that the transfer gripper 52 can grasp the workpiece 300 to be inspected and place the workpiece 300 to be inspected in the positioning slot 411 of the inspection platform 41.

[0044] Next, the detection drive 421 drives the support 422 to move, thereby causing the detector 423 to pass over the detection platform 41 to detect the workpiece 300. After the detection is completed, the detection drive 421 drives the support 422 to move again, thereby causing the rejection gripper 43 to move to the defective workpiece 300. The rejection gripper 43 grabs the defective workpiece 300 and moves it above the scrap box 44 under the drive of the detection drive 421 to place the defective workpiece 300 into the scrap box 44.

[0045] After inspection, the transfer drive 51 drives the transfer gripper 52 to transfer the qualified workpiece 300 to the tray 200 positioned by the receiving mechanism 30. After all the workpieces 300 in the uppermost tray 200 of the feeding mechanism 20 have been removed, the empty tray 200 can be transferred to the receiving position 12 by the transfer drive 51 and the transfer gripper 52 for receiving.
