[0031] The present invention will now be further described in conjunction with specific embodiments.

[0032] For glass components such as screens, in addition to inspecting the surfaces on both sides, it is sometimes necessary to inspect the four edges of the screen to ensure that the screen is intact and free of defects. Therefore, when the screen is assembled into an electronic product, it is sent to the inspection station for testing to eliminate defective products.

[0033] like Figure 1 and Figure 2 As shown, this type of workpiece inspection line for glass components such as screens includes a loading section A, an inspection section B, and an unloading section C arranged sequentially. Loading section A includes a loading conveyor belt 100 mounted on the machine base 5, which transports the workpieces to be inspected from the previous station to inspection section B. To improve inspection efficiency, multiple loading conveyor belts 100 are typically used to simultaneously transport multiple screens to a corresponding number of fixtures in inspection section B for inspection. In this embodiment, loading section A includes four loading conveyor belts 100.

[0034] The unloading section C includes unloading conveyor belts 200 mounted on the machine base 5, the number of which corresponds to the number of loading conveyor belts 100. The unloading conveyor belts 200 are used to transfer inspected workpieces to the next workstation. Both the loading conveyor belts 100 and the unloading conveyor belts 200 can be conventional motor-driven belt conveyors.

[0035] Inspection section B is used for inspecting the screen. Inspection section B includes at least one inspection station. To improve inspection efficiency, in this embodiment, inspection section B includes four inspection stations (B1, B2, B3, and B4), each used to inspect the two side surfaces and the four edges of the screen, respectively. Each inspection station is equipped with a vision module, such as a CCD, corresponding to the number of 100 units on the feeding conveyor belt, which can simultaneously photograph the workpieces to be inspected. In this embodiment, each inspection station is equipped with four optical modules Q, allowing four workpieces to be inspected at a time at each station.

[0036] The docking conveyor mechanism is located between the loading section A and the inspection section B, and between the inspection section B and the unloading section C. The docking conveyor structure includes a conveying fixture 1, a pitch-changing module 2, an inspection fixture 3, and a translation module 4. The conveying fixture 1 is mounted on the pitch-changing module 2, and the inspection fixture 3 is mounted on the translation module 4. The conveying fixture 1 is used to dock with the conveyor belts (loading conveyor belt 100 and unloading conveyor belt 200) to receive workpieces from the conveyor belts or to transfer workpieces onto the conveyor belts. The inspection fixture 3 is used to carry the workpieces to be inspected to the inspection station for inspection.

[0037] The pitch module 2 is mounted on the machine base 5, and can change the spacing between the conveying fixtures 1 mounted on it. The pitch module 2 can be an existing product, such as the pitch module sold by Haijie Jiachuang Technology Co., Ltd.

[0038] like Figure 1 As shown, the spacing between the feeding conveyor belts 100 in the feeding section A is different from the spacing between the inspection fixtures 3 in the inspection station of the inspection section B (the spacing of the inspection fixtures 3 corresponds to the spacing of the vision modules). When the conveying fixture 1 receives the workpiece to be inspected from the feeding conveyor belt 100, the pitch-changing module 2 adjusts the distance between the conveying fixtures 1 so that the conveying fixture 1 can dock with the feeding conveyor belt 100, so that the workpiece to be inspected can be transferred from the feeding conveyor belt 100 to the conveying fixture 1; then the pitch-changing module 2 adjusts the distance between the conveying fixtures 1 again so that the conveying fixture 1 can dock with the inspection fixture 3, so that the workpiece to be inspected can be transferred from the conveying fixture 1 to the inspection fixture 3.

[0039] like Figure 3 As shown, the conveying fixture 1 in this embodiment includes a first conveyor belt support 1-1, a first conveyor belt 1-2, a first limiting part 1-3, and a first limiting part lifting drive unit 1-4. The first conveyor belt support 1-1 is disposed on the platform of the variable pitch module 2. When the variable pitch module 2 adjusts the distance between the platforms, the position of the first conveyor belt support 1-1 can be adjusted, thereby adjusting the position of the conveying fixture 1.

[0040] The first conveyor belt 1-2 is mounted on the first conveyor belt support 1-1. The first conveyor belt 1-2 can be a conventional motor-driven conveyor belt. The workpiece to be inspected, delivered by the feeding conveyor belt 100, is conveyed onto the inspection fixture 3 via the first conveyor belt 1-2. In this embodiment, two first conveyor belts 1-2 are respectively arranged on both sides of the first conveyor belt support 1-1. In other embodiments, only one wider first conveyor belt may be arranged. A first limiting part 1-3 is provided at the discharge end of the first conveyor belt 1-2. The first limiting part 1-3 is mounted on the first conveyor belt support 1-1 and can be raised and lowered. The raising and lowering of the first limiting part 1-3 is controlled by the first limiting part raising and lowering drive unit 1-4. In this embodiment, the first limiting part raising and lowering drive unit 1-4 is a cylinder. The cylinder is mounted on the first conveyor belt support 1-1, and the piston rod of the cylinder is connected to the first limiting part 1-3. When the cylinder is activated, it drives the first limiting part 1-3 to move up and down. By setting the first limiting part 1-3, when the first limiting part 1-3 is raised, it can block the workpiece to be inspected on the first conveyor belt 1-2, preventing the workpiece to be inspected from moving forward. When it is necessary to convey the workpiece to be inspected, the first limiting part 1-3 is lowered, allowing the workpiece to be inspected to be conveyed backward.

[0041] The inspection fixture 3 is mounted on the translation module 4, which can move between the inspection stations in inspection section B. Inspection fixtures 3 mounted on the same translation module 4 form a group, with one inspection station corresponding to one group of inspection fixtures 3. The number of inspection fixtures 3 in one group corresponds to the number of optical modules installed at one inspection station. For example, in this embodiment, four inspection fixtures 3 are mounted on one translation module 4, and four vision modules are installed at one inspection station. After receiving the workpiece to be inspected from the conveying fixture 1, the set of inspection fixtures 3 corresponding to inspection station B1 transports the workpiece to be inspected to the vision module Q of inspection station B1 for inspection, and then transfers it to the set of inspection fixtures 3 corresponding to inspection station B2; after receiving the workpiece to be inspected from the inspection fixture 3 of inspection station B1, the set of inspection fixtures 3 corresponding to inspection station B2 transports the workpiece to be inspected to the vision module Q of inspection station B3 for inspection, and then transfers it to the set of inspection fixtures 3 corresponding to inspection station B3; and so on. After receiving the workpiece to be inspected from the inspection fixture 3 of the previous inspection station, the inspection fixture 3 of each inspection station transports the workpiece to be inspected to the vision module Q of the corresponding inspection station for inspection, and then transfers it to the next inspection station; until the workpiece to be inspected has been inspected by all inspection stations, it is then transferred to the unloading section C.

[0042] like Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the inspection fixture 3 in this embodiment includes a second conveyor belt support 3-1, a second conveyor belt 3-2, a second limiting part 3-3, a second limiting part lifting drive unit 3-4, a base 3-5, a support lifting drive unit 3-6, a workpiece suction cup 3-7, a suction cup support 3-8, and a suction cup rotation drive unit (not shown).

[0043] The structures of the second conveyor belt support 3-1, the second conveyor belt 3-2, the second limiting part 3-3, and the second limiting part lifting drive unit 3-4 are the same as those of the first conveyor belt support 1-1, the first conveyor belt 1-2, the first limiting part 1-3, and the first limiting part lifting drive unit 1-4. Please refer to the previous description of the conveying fixture structure, which will not be repeated here.

[0044] The second conveyor belt support 3-1 is movably mounted on the base 3-5. The second conveyor belt support 3-1 is controlled to rise and fall by the support lifting drive unit 3-6. In this embodiment, the support lifting drive unit 3-6 is a cylinder, which is fixedly mounted on the base 3-5. The piston rod of the cylinder is connected to the second conveyor belt support 3-1. When the cylinder is activated, it can drive the second conveyor belt support 3-1 to move up and down.

[0045] The workpiece suction cup 3-7 is mounted on the base 3-5 via a suction cup bracket 3-8. The suction cup bracket 3-8 can rotate 360° along its own axis under the control of a rotary drive unit (not shown). Figure 7 As shown, the workpiece suction cup 3-7 is disposed on the top of the suction cup bracket 3-8, and the workpiece suction cup 3-7 can adsorb the workpiece 300 to be inspected. In this embodiment, two second conveyor belts 3-2 are respectively disposed on both sides of the second conveyor belt bracket 3-1, and the workpiece suction cup 3-7 is located between the two second conveyor belts 3-2. Multiple workpiece suction cups 3-7 can be disposed on the suction cup bracket 3-8 to better adsorb the workpiece.

[0046] As the second conveyor belt support 3-1 lowers the second conveyor belt 3-2, the workpiece to be inspected also descends until it contacts and is held by the workpiece suction cup 3-7. The second conveyor belt support 3-1 continues to descend, as... Figure 8 , Figure 9 and Figure 10 As shown, the workpiece 300 to be inspected is held by the workpiece suction cup 3-7 and no longer descends with the second conveyor belt 3-2. Instead, it moves upward relative to the second conveyor belt 3-2 and leaves the second conveyor belt 3-2. Thus, when the suction cup rotation drive unit drives the suction cup bracket 3-8 to rotate around its own axis, the workpiece suction cup 3-7 set on the suction cup bracket 3-8 can drive the workpiece to be inspected to rotate together, thereby inspecting the four edges of the workpiece to be inspected.

[0047] The base 3-5 is rotatably mounted on the support of the translation module 4 around a horizontal axis. The inspection fixture 3 can move with the translation module 4 between adjacent inspection stations, thereby realizing the transfer of the workpiece to be inspected between each inspection station. The rotation axis of the base 3-5 is perpendicular to the conveying direction of the conveyor belt.

[0048] The docking conveyor mechanism between inspection section B and unloading section C has the same structure as the docking conveyor mechanism between loading section A and inspection section B, also including conveying fixture 1, pitch-changing module 2, inspection fixture 3, and translation module 4, except that the order of conveying fixture 1 and inspection fixture 3 is reversed. In the docking conveyor mechanism between loading section A and inspection section B, conveying fixture 1 is in front and inspection fixture 3 is behind, with conveying fixture 1 docking with the loading conveyor belt 100 of loading section A; in the docking conveyor mechanism between inspection section B and unloading section C, inspection fixture 3 is in front and conveying fixture 1 is behind, with conveying fixture 1 docking with the unloading conveyor belt 200 of unloading section C. The docking conveyor mechanism between inspection section B and unloading section C will not be described in detail here. Each inspection station in inspection section B is equipped with a translation module 4 and an inspection fixture 3 mounted on the translation module 4, used to realize the transfer and inspection of the workpiece to be tested between adjacent inspection stations. The structure of the translation module 4 and the inspection fixture 3 is the same as that of the translation module 4 and the inspection fixture 3 of the docking and conveying mechanism, and will not be described again here.

[0049] like Figure 11 As shown, the inspection fixtures 3 of adjacent inspection stations can transfer the workpieces to be inspected by translation. In this docking and transfer method, the second conveyor belt of the inspection fixture 3 is horizontal, and the workpiece 300 to be inspected can be directly transferred from the second conveyor belt of one inspection fixture 3 to the second conveyor belt of the next inspection fixture 3. The conveying fixture and the inspection fixture also use this method to dock and transfer workpieces.

[0050] like Figure 12 and Figure 13 As shown, adjacent inspection fixtures 3 can also connect and transfer the workpieces to be inspected via a handshake mechanism. The base of the inspection fixture 3 is rotatably mounted on the support of the translation module 4. When receiving the workpiece, the base 3-5 flips so that the inspection fixture 3 is in a vertical position, and the workpiece to be inspected is held by the workpiece suction cup and will not fall. After the workpiece suction cup of the next inspection fixture 3 picks up the workpiece to be inspected, the workpiece suction cup of the previous inspection fixture 3 releases air and releases the workpiece to be inspected. When the translation module 4 moves, the base 3-5 rotates to a horizontal position, and the inspection fixture 3, carrying the workpiece to be inspected, moves backward with the translation module 4. The translation module 4 can be a linear module, a translation support controlled by a motor or other drive unit, etc.

[0051] The detection process of the workpiece inspection line in this embodiment is as follows:

[0052] After the glass workpiece is transferred from the previous station to the feeding section A, it is placed on the feeding conveyor belt 100 and conveyed backward by the feeding conveyor belt 100 to the inspection section B. The docking conveyor mechanism located at the feeding end of the inspection section B docks with the discharge end of the feeding conveyor belt 100. At this time, the conveying fixture 1 on the variable pitch module 2 is combined, so that the workpiece to be inspected can be received from the feeding conveyor belt 100.

[0053] After the workpiece to be inspected is transferred to the conveying fixture 1, the variable pitch module 2 adjusts the distance between the conveying fixtures 1, and the conveying fixtures 1 open at equal intervals so that the distance between the conveying fixtures 1 corresponds to the distance between the inspection fixtures 3 on the translation module 4, so that the workpiece to be inspected can be transferred to the inspection fixture 3.

[0054] After the workpiece to be inspected is transferred to the inspection fixture 3, the translation module 4 moves the inspection fixture 3 backward to below the vision module of the inspection station. At this time, the workpiece is carried by the second conveyor belt 3-2, and the vision module can inspect the surface of the glass workpiece. When it is necessary to inspect the four edges of the glass workpiece, the bracket lifting drive unit 3-6 controls the second conveyor belt bracket 3-1 to move the second conveyor belt 3-2 downward relative to the workpiece to be inspected. The workpiece to be inspected is separated from the second conveyor belt 3-2, and the workpiece is held by the workpiece suction cup 4-7. Then the base 3-5 is rotated 90° until the second conveyor belt 3-2 is in a vertical state. The suction cup bracket 3-8 can rotate 360°, so that the four edges of the glass workpiece can be visually inspected. After the inspection is completed, the base 3-5 is rotated 90° in the opposite direction until the second conveyor belt 3-2 is in a horizontal state. The bracket lifting drive unit 3-6 controls the second conveyor belt bracket 3-1 to move the second conveyor belt 3-2 upward to support the workpiece again. The workpiece suction cup 4-7 releases air and releases the workpiece. The second conveyor belt 3-2 then transports the workpiece backward.

[0055] After the workpieces to be inspected pass through the corresponding inspection stations in sequence and complete the inspection, the inspection fixture 3 of the last inspection station moves the workpiece to the unloading section C. The docking conveyor mechanism located at the discharge end of the inspection section B docks with the inlet end of the unloading conveyor belt 200. The inspection fixture 3 transfers the workpiece to the conveying fixture 1 of the docking conveyor mechanism. The pitch-changing module 2 controls the pitch of the conveying fixture 1 to change and join together so as to dock with the unloading conveyor belt 200. The conveying fixture 1 transfers the workpiece to the unloading conveyor belt 200, and the unloading conveyor belt 200 transfers the workpiece to the next station.
