Technical Field

[0001] This utility model relates to the field of prism end face detection technology, and in particular to a device for detecting the end face of a long prism. Background Technology

[0002] The inspection of the end face of a long triangular prism requires high dimensional accuracy and a large number of dimensions. Currently, this is generally done manually by employees using a 2D camera. The manual inspection process involves: placing the long prism vertically, attaching end face 1 to a 2D moving platform using double-sided tape, then moving the platform under the lens of the 2D camera to inspect end face 2. Then, the prism is flipped over, end face 2 is attached, and end face 1 is inspected again. This inspection method is inefficient and has a high probability of touching the effective area of ​​the product, causing coating marks in subsequent processes. Therefore, there is an urgent need to increase the automation rate of the production line and improve inspection efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a device for inspecting the end face of a long prism, which solves the problems of low efficiency and easy contact with the effective area of ​​the product caused by manual inspection at the present stage.

[0004] To address the aforementioned problems, this utility model provides a device for inspecting the end faces of a long prism, comprising a feeding assembly, a discharging assembly, a robot body, a clamp, a support unit, and an optical camera module. The clamp is connected to the robot body and includes at least two sets of gripping bodies. When gripping materials, the two sets of gripping bodies clamp the end faces of the materials at their respective ends. The robot body picks up the materials from the feeding assembly and places the inspected qualified and unqualified materials into the feeding assembly and the discharging assembly, respectively. Two sets of support units are provided to support the ineffective areas at both ends of the materials. At least one set of support units is movably installed to adjust the distance between the two sets of support units. Each support unit includes a support body and a support plate disposed on the support body. The support plate is provided with a positioning groove for placing materials. Two sets of optical camera modules are provided to inspect the end faces of the materials.

[0005] This solution offers higher testing efficiency. The elongated prism will not come into contact with the effective area during the transfer and testing processes, thus avoiding any impact on subsequent product processing.

[0006] According to one embodiment of the present invention, the support plates are provided in several groups, and the support plates are provided with connecting structures. Any group of support plates can be combined to support materials.

[0007] Adjust the number of support plates used for support based on the length of the ineffective zone of the elongated prism being tested to ensure stable support.

[0008] According to one embodiment of the present invention, the bottom positions of adjacent support plates are connected in a movable manner, so that the support plates have a supported state and an idle state.

[0009] Alternatively, the movable connection can be a hinge connection or a flexible connecting piece connection.

[0010] Optionally, the connection structure includes a plug-in connection structure or a magnetic adsorption structure.

[0011] According to one embodiment of the present invention, the support body is provided with a clearance groove for avoiding the clamping body, so as to prevent the clamping body from colliding with the support body when placing the long strip prism on the support plate.

[0012] According to one embodiment of the present invention, the clamp includes a finger cylinder, and the clamping body is the two finger portions of the finger cylinder.

[0013] According to one embodiment of the present invention, the elongated prism end face detection device further includes a light source module.

[0014] According to one embodiment of the present invention, the feeding assembly includes a feeding basket, and the unloading assembly includes an unloading basket.

[0015] Alternatively, the feeding and unloading components may also adopt structures such as fixed material placement stations or material conveyor belts.

[0016] According to one embodiment of the present invention, the support body is provided with a base end, and the base end of the movable support part is installed at the waist-shaped mounting hole through a connector.

[0017] According to one embodiment of the present invention, when the material is placed in the positioning groove, the edges of the material do not contact the inner wall of the positioning groove, thus avoiding collision with the edges of the elongated prism.

[0018] The beneficial effects of this utility model are that by using a robot to load and unload materials, and by using a support part to support the ineffective areas at both ends of the material, and with the help of two sets of optical camera modules, both end faces can be detected simultaneously, resulting in higher detection efficiency. Furthermore, the long prism will not come into contact with the effective area during the transfer and detection process, thus avoiding affecting the subsequent processing of the product. In addition, this solution is also applicable to long prisms of various lengths. Attached Figure Description

Detailed Implementation

[0026] The following description is only intended to disclose the present invention so that those skilled in the art can implement it. The embodiments in the following description are merely examples, and those skilled in the art will conceive of other obvious modifications. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other solutions that do not depart from the spirit and scope of the present invention.

[0027] Example 1:

[0028] A device for detecting the end face of a long prism, such as Figures 1-3 It includes an equipment frame 1, a feeding assembly, a discharging assembly, a light source module 4, a robot body 5, a fixture, a support unit 7, and an optical camera module 8.

[0029] The equipment frame 1 has a worktable, and the loading component, unloading component, robot body 5, fixture, support 7, light source module 4 and optical camera module 8 are all arranged on the worktable.

[0030] In this embodiment, the feeding assembly includes a feeding basket 2 and the unloading assembly includes a unloading basket 3. The feeding basket 2 is used to place the long strip prism 9 to be inspected and the qualified long strip prism 9 after inspection, and the unloading basket 3 is used to place NG products.

[0031] The clamp is connected to the robot body 5. The clamp includes at least two sets of clamping bodies. When clamping materials, the two sets of clamping bodies clamp the two end faces of the materials respectively. In this embodiment, the clamp includes a finger cylinder 6 and the clamping bodies are the two finger parts of the finger cylinder 6. In other embodiments, electric clamping fingers can also be used.

[0032] The robot body 5 preferably adopts a 6-axis robotic arm, with two finger cylinders installed on the rotating gripper of the 6th axis.

[0033] Two sets of support parts 7 are provided to support the ineffective areas at both ends of the material. At least one set of support parts 7 is movable to adjust the distance between the two sets of support parts 7.

[0034] like Figure 3 The support part 7 includes a support body 77 and a support plate 72 disposed on the support body 77. The support body 77 includes a base end 71 at the bottom and a support end at the top. The support plate 72 is disposed at the support end and is provided with a positioning groove 73 for placing materials. The upper section of the positioning groove 73 is a contoured structure and the lower section is a clearance groove. When the material is placed in the positioning groove 73, the edges of the material do not contact the inner wall of the positioning groove 73, thus avoiding collision with the edges of the elongated prism 9.

[0035] The base end 71 of the movable support part 7 is installed at the waist-shaped mounting hole 10 through a connector, which is generally a bolt. The base end 71 is provided with a through hole. When testing long strip prisms 9 of different lengths, the distance between the two support parts 7 is adjusted by adjusting the installation position of the support part 7 in the waist-shaped mounting hole 10. The fixed support part 7 is installed on the workbench with bolts.

[0036] The support body 77 is provided with a clearance groove 74 to avoid the clamping body from colliding with the support body 77 when the clamping body is placed on the support piece 72.

[0037] Two sets of optical camera modules 8 are set on the outside of the two support parts 7 respectively, and are used to detect the two end faces of the material. The light source module 4 can be set between the optical camera module 8 and the support part 7 (using a ring light source module 4), or it can be set at other positions that can illuminate the end face of the long strip prism 9.

[0038] Preferably, the optical camera module 8 on the outer side of the movable support 7 is also movable, and its position can be adjusted by using a slotted hole or by mounting on a slide rail.

[0039] Using this solution, the detection efficiency is higher. During the transfer and detection process of the elongated prism 9, it will not come into contact with the effective area, thus avoiding affecting the subsequent processing of the product.

[0040] Testing steps:

[0041] Employees place the loading basket (with material) and unloading basket (empty) into the designated positions on the equipment;

[0042] The 6-axis robotic arm uses finger cylinders to grip both ends of a long strip prism, removes it from the loading basket, and places it on the support part 7 of the inspection platform.

[0043] The optical camera module 8 performs testing;

[0044] Once the testing agency completes the inspection, it sends an OK or NG signal to the robotic arm. The robotic arm then performs the unloading action based on the signal (OK or NG). If OK, the wafer is returned to the loading basket; if NG, the wafer is placed in the NG unloading basket. The equipment stops operating once all wafers in the loading basket have been inspected. The employee then removes the two baskets and replaces them with new ones.

[0045] Example 2:

[0046] Based on Example 1, this example can adjust the support area at the support position by adjusting the number of support pieces 72, which is suitable for different invalid region lengths of long strip prisms 9 of different lengths, and ensures stable support.

[0047] like Figures 4-5 Several sets of support plates 72 are provided, and a connecting structure is provided on the support plates 72. Any set of support plates 72 can be combined to support the material. According to the length of the invalid region of the detected long strip prism 9, for example, a long strip prism 9 with an invalid region length of 1.5mm is supported by one support plate 72, and a longer long strip prism 9 with an invalid region length of 3mm is supported by two support plates 72. By adjusting the number of support plates 72 used for support, stable support is ensured.

[0048] Specifically, the bottom positions of adjacent support plates 72 are connected in a movable manner, so that the support plates 72 can have a supported state and an idle state.

[0049] Alternatively, the movable connection can be a hinge connection or a flexible connecting piece connection.

[0050] Preferably, the bottom positions of adjacent support pieces 72 are connected by flexible connecting pieces, such as plastic bags or cloth strips, so that the support pieces 72 can rotate. Figure 5 In this embodiment, there is a support plate 72 fixed on the support body 77 and two support plates 72 that are movably connected. In the support state, the support plate 72 is rotated to coincide with the previous support plate 72. In the idle state, the support plate 72 is flipped downward.

[0051] Optionally, the connection structure includes a plug-in connection structure or a magnetic adsorption structure.

[0052] In this embodiment, a magnetic adsorption structure is preferably adopted, with iron sheet 75 and magnet 76 respectively provided on the opposite end face of two adjacent support sheets 72, which are adsorbed and connected when they overlap.

[0053] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functional and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations and modifications.
