Description

Technical Field

[0001] The present invention relates to a flipping device, a flipping method, a detection device and a detection method, and in particular to a flipping device, a flipping method, a detection device and a detection method for flipping a plate-shaped object to be tested. Background Art

[0002] When inspecting a plate-shaped object for surface defects, existing inspection equipment typically uses a conveyor belt to transport the object to an image capture device, which first captures an image of the object's upper surface for subsequent defect detection. The conveyor belt then transports the object to a flipping device, which flips it so that its lower surface faces upward. The conveyor then transports the object back to the image capture device, which captures an image of its lower surface for subsequent defect detection.

[0003] Because the image capture device and flipping device are located in two different workstations and are independent devices, the object to be tested must be transported between the image capture device and the flipping device via a conveyor belt in order to perform the image capture and flipping operations, respectively. This results in a very long labor-intensive process, resulting in poor inspection speed and efficiency. Furthermore, the flipping device uses two clamping mechanisms to clamp the object to be tested on opposite sides to flip it. Since each clamping mechanism only contacts a small area of ​​the object when clamping it, the object to be tested is prone to shaking during the process of being flipped by the two clamping mechanisms, resulting in poor stability during flipping. Summary of the Invention

[0004] Therefore, one of the objects of the present invention is to provide a flipping device that can overcome at least one disadvantage of the background art.

[0005] The purpose of the present invention and the background technical problems to be solved are achieved by adopting the following technical solutions. The flipping device proposed in the present invention includes a clamping mechanism and a rotating mechanism. The clamping mechanism includes two pressing assemblies, which are arranged in opposite directions along a longitudinal direction. Each pressing assembly includes two pressing plates for supporting or pressing an object to be tested. The pressing plates are arranged along a first transverse direction perpendicular to the longitudinal direction and can be transformed between an open state and a closed state. The two pressing assemblies can be transformed between an open state and a clamping state. The rotating mechanism is used to drive the clamping mechanism to rotate so that the clamping mechanism drives the clamped object to be tested to rotate.

[0006] Another object of the present invention is to provide a detection device that can overcome at least one disadvantage of the background art.

[0007] The purpose of the present invention and the background technical problem to be solved are achieved by adopting the following technical solutions. The detection equipment proposed by the present invention includes a flipping device as described above, an image capture device, and a pick-and-place device. The image capture device is located longitudinally above the clamping mechanism. When the pressing assembly is in an open state and the pressing plate of the corresponding pressing assembly located above is in an open state, an opening is defined between the two pressing plates. The image capture device corresponds to the position of the opening and can capture the image of the object to be tested carried by the pressing plate of the corresponding pressing assembly located below. The pick-and-place device can pick up and place the object to be tested through the opening.

[0008] Another object of the present invention is to provide a flipping method that can overcome at least one disadvantage of the background art.

[0009] The purpose of the present invention and the background technology problem to be solved are achieved by adopting the following technical solutions. The flipping method proposed by the present invention comprises the following steps:

[0010] A test object is placed on the lower pressing assembly of the two pressing assemblies arranged vertically, with the two pressing plates of the lower pressing assembly in a closed state and the two pressing plates of the upper pressing assembly in an open state;

[0011] Driving the pressing plate of the pressing assembly located above to change to a closed state;

[0012] Driving the pressing assembly to change from an open state to a clamping state for clamping the object to be measured;

[0013] The pressing assembly is driven to rotate the clamped object to be tested;

[0014] Driving the pressing assembly to change from a clamping state to an open state; and

[0015] The pressing plate of the pressing assembly located above is driven to change from a closed state to an open state.

[0016] Another object of the present invention is to provide a detection method that can overcome at least one disadvantage of the background art.

[0017] The purpose of the present invention and the problem to be solved are achieved by adopting the following technical solutions. The detection method proposed by the present invention comprises the following steps:

[0018] A test object is placed on the lower pressing assembly of the two pressing assemblies arranged vertically, with the two pressing plates of the lower pressing assembly in a closed state and the two pressing plates of the upper pressing assembly in an open state;

[0019] Capturing a first surface image of the object to be measured by an image capturing device;

[0020] Driving the pressing plate of the pressing assembly located above to change to a closed state;

[0021] Driving the pressing assembly to change from an open state to a clamping state for clamping the object to be measured;

[0022] The pressing assembly is driven to rotate the clamped object to be tested;

[0023] Driving the pressing assembly to change from a clamping state to an open state;

[0024] Driving the pressing plate of the pressing assembly located above to change from a closed state to an open state; and

[0025] The image of the second side of the object to be tested is captured by an image capture device. The beneficial effect of the present invention is that the image capture device is arranged longitudinally above the clamping mechanism of the flipping device, so that the image capture and flipping operations of the object to be tested can be completed at a single workstation, which can save the conveying equipment and conveying time required for transfer between two different workstations. Therefore, the detection speed and efficiency can be greatly improved, and the manufacturing cost of the detection equipment can be reduced. In addition, since the plate surfaces of the two pressing plates of the pressing assembly contact and press against the first and second surfaces of the object to be tested in a surface contact manner, the stability when clamping the object to be tested can be effectively increased, and the stability when the pressing assembly drives the object to be tested to rotate can be improved.

[0034] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0035] See Figure 1 , an embodiment of the detection device 200 of the present invention is an optical detection device for example, which is suitable for detecting surface defects of an object to be tested 1. In one embodiment, the object to be tested 1 is a plate, for example, it can be an opaque circuit substrate, a panel, or a wafer substrate, but is not limited thereto. The object to be tested 1 has a first surface 11 and a second surface 12 opposite to the first surface 11. The detection device 200 includes a flipping device 20, a pick-and-place device 30 and an image capture device 40. For the convenience of subsequent description, a longitudinal direction Z, a first lateral direction X perpendicular to the longitudinal direction Z, and a second lateral direction Y perpendicular to the first lateral direction X and the longitudinal direction Z of the detection device 200 are defined. The longitudinal direction Z is the up and down direction, the first lateral direction X takes the left and right direction as an example, and the second lateral direction Y takes the front and back direction as an example.

[0036] See Figure 1 and Figure 2 The flipping device 20 includes a support base 2, a clamping mechanism 3, and a rotating mechanism 4. The support base 2 is U-shaped with its opening facing upward, and includes two support plates 21 spaced apart along the second transverse direction Y. The clamping mechanism 3 includes two pressing assemblies 31, 31', and a drive assembly 35. The two pressing assemblies 31, 31' are arranged in opposite directions along the longitudinal direction Z and arranged vertically, with the pressing assembly 31 located at the bottom and the pressing assembly 31' located at the top. The two pressing assemblies 31, 31' have the same structure.

[0037] See Figure 3 、 Figure 4 、 Figure 5 and Figure 6 The pressing assembly 31 includes two pressing plates 32a and a drive unit 33. The pressing assembly 31' includes two pressing plates 32b and a drive unit 33. The two pressing plates 32a are arranged along a first transverse direction X, and the two pressing plates 32b are arranged along a second transverse direction X. Each pressing plate 32a, 32b includes a main plate 321, an inner plate 322, an outer plate 323, and two side plates 324. The main plate 321 has a plate surface 325 for supporting or pressing against the object under test 1. The inner plate 322 and the outer plate 323 are respectively connected vertically to opposite sides of the main plate 321 and spaced apart along the first transverse direction X. The two side plates 324 are respectively connected vertically to the other two opposite sides of the main plate 321 and spaced apart along the second transverse direction Y. The inner plates 322 of the two pressing plates 32a can be spaced adjacent to or facing each other, while the outer plates 323 can be spaced apart from each other. The inner plates 322 of the two pressing plates 32 b can be adjacent to or spaced apart from each other, while the outer plates 323 can be spaced apart from each other.

[0038] The driving unit 33 includes two side plates 331 and two driving modules 332. The two side plates 331 are arranged in opposite directions along the second transverse direction Y and are spaced apart. Each side plate 331 has an inner side surface 333 and an outer side surface 334 opposite to the inner side surface 333. The two driving modules 332 are arranged on the two side plates 331 in opposite directions along the second transverse direction Y. Each driving module 332 includes two first slide rail groups 335, a connecting frame 336, and a first cylinder 337. The two first slide rail groups 335 are respectively arranged on the inner side surfaces 333 of the two side plates 331. The connecting frame 336 of each driving module 332 is connected between the two first slide rail groups 335 to support and fix the main plate 321 of the corresponding pressure plate 32a, 32b on a side opposite to the plate surface 325. The connecting frame 336 can smoothly drive the corresponding pressing plates 32a, 32b to move along the first transverse direction X under the guidance of the two first slide rail assemblies 335. The first cylinder 337 is provided on the outer side surface 334 of the corresponding side plate 331 and is connected to the connecting frame 336. Each first cylinder 337 drives the corresponding connecting frame 336 so that the connecting frame 336 drives the corresponding pressing plates 32a, 32b connected thereto to move along the first transverse direction X to a closed position (such as Figure 4 ), and an open position (as shown Figure 6 Move between the

[0039] When the two pressing plates 32a are in the closed position, the inner plates 322 of the two pressing plates 32a are pressed against each other, so that the two pressing plates 32a are in a closed state. At this time, the plate surfaces 325 of the two pressing plates 32a can jointly bear or press against the object to be tested 1. When the two pressing plates 32b are in the closed position, the inner plates 322 of the two pressing plates 32b are pressed against each other, so that the two pressing plates 32b are in a closed state. At this time, the plate surfaces 325 of the two pressing plates 32b can jointly bear or press against the object to be tested 1. When the two pressing plates 32a are in the open position, the inner plates 322 of the two pressing plates 32a are far away from each other and spaced apart, so that the two pressing plates 32a are in an open state. At this time, an opening 34 is defined between the inner plates 322 of the two pressing plates 32a, and the opening 34 is used for the object to be tested 1 (such as Figure 1 As shown) and the pick-and-place device 30 (as Figure 1 When the two pressing plates 32b are in the open position, the inner plates 322 of the two pressing plates 32b are spaced apart from each other, so that the two pressing plates 32b are in the open state. At this time, an opening 34 is defined between the inner plates 322 of the two pressing plates 32b. The opening 34 is used for the object to be tested 1 (as shown) to pass through. Figure 1 As shown) and the pick-and-place device 30 (as Figure 1 Thus, the driving unit 33 can drive the two pressing plates 32a and the two pressing plates 32b to move in opposite directions along the first transverse direction X and switch between the open state and the closed state.

[0040] See Figure 2 、 Figure 3 and Figure 4 By arranging the two pressing assemblies 31 and 31' in opposite directions along the longitudinal direction Z, the two side plates 331 of the drive unit 33 in opposite directions along the second transverse direction Y, and the two drive modules 332 on the two side plates 331 in opposite directions along the second transverse direction Y, the pressing assemblies 31 and 31' are relatively simple in design and manufacture, reducing structural complexity. Furthermore, by connecting the connecting brackets 336 of each drive module 332 between the two first rail assemblies 335, the two first rail assemblies 335 provide effective support and guidance for the connecting brackets 336 and the pressing plates 32a and 32b to which they are connected, thereby enhancing the stability and smoothness of the movement of the pressing plates 32a and 32b.

[0041] See Figure 1 and Figure 2 The drive assembly 35 includes four second slide rail groups 351 and two second cylinders 352. The four second slide rail groups 351 are grouped in pairs, and the two second slide rail groups 351 in each group are spaced apart along the first transverse direction X, and are connected to the outer side surface 334 of the corresponding side plate 331 of the pressing assembly 31, 31' arranged along the longitudinal direction Z. In one embodiment, each second cylinder 352 is, for example, a clamping cylinder, but is not limited to this. Each second cylinder 352 is located between the two second slide rail groups 351 of the corresponding group, and has two actuating blocks 353 that are spaced apart along the longitudinal direction Z and can move in opposite directions along the longitudinal direction Z. The two actuating blocks 353 are respectively connected to the outer side surface 334 of the corresponding side plate 331 of the pressing assembly 31, 31' arranged along the longitudinal direction Z. Each second cylinder 352 of the driving assembly 35 drives the two pressing assemblies 31 and 31' to move in opposite directions along the longitudinal direction Z through the two actuating blocks 353, so that the two pressing assemblies 31 and 31' are in an open state away from each other (such as Figure 10 As shown), and a clamping state close to each other (as shown Figure 11 In the open state, the two pressing plates 32a of the pressing assembly 31 in the closed state and the two pressing plates 32b of the pressing assembly 31' in the closed state do not clamp the object under test 1. In the clamping state, the two pressing plates 32a of the pressing assembly 31 in the closed state and the two pressing plates 32b of the pressing assembly 31' in the closed state do clamp the object under test 1.

[0042] By using a clamping cylinder as the second cylinder 352, the second cylinder 352 can simultaneously drive the two pressure-receiving assemblies 31 and 31' to move in opposite directions along the longitudinal direction Z. This can also shorten the travel distance of the two pressure-receiving assemblies 31 and 31' when switching between the open state and the clamped state, thereby improving the speed and efficiency of the switching. Furthermore, by using two second cylinders 352, the force balance and stability when driving the two pressure-receiving assemblies 31 and 31' to move in opposite directions along the longitudinal direction Z can be improved. Furthermore, by having each set of two second slide rail assemblies 351 located on opposite sides of the corresponding second cylinder 352, the two second slide rail assemblies 351 can effectively support and guide the corresponding side plates 331 of the two pressure-receiving assemblies 31 and 31' arranged along the longitudinal direction Z, thereby improving the stability and smoothness of the movement of the two pressure-receiving assemblies 31 and 31'. Of course, the number of second slide rail assemblies 351 can also be two, and they can be respectively located on one side of the two second cylinders 352, and are not limited to the embodiment disclosed.

[0043] The rotating mechanism 4 includes a transmission frame 41, a pivot 42, and an actuating assembly 43. The transmission frame 41 has two side frames 411 spaced apart along the second transverse direction Y, and two connecting frames 412 connected between the two side frames 411 and spaced apart along the first transverse direction X. Each side frame 411 is located outside the corresponding side plate 331. The two connecting frames 412 are located between the two pressing assemblies 31, 31'. Each second cylinder 352 and two second slide rail assemblies 351 corresponding to each second cylinder 352 are disposed inside the corresponding side frame 411, so that the driving assembly 35 is connected between the side plates 331 of the two pressing assemblies 31, 31' and the transmission frame 41. The pivot 42 is rotatably pivoted to one of the two support plates 21 and connected to the outside of the corresponding side frame 411 of the transmission frame 41. The actuator assembly 43 is mounted on the other support plate 21 and includes a motor 431 and a transmission assembly 432 connected between the motor 431 and the outer side of the corresponding side frame 411 of the transmission frame 41. The motor 431 drives the transmission frame 41 through the transmission assembly 432 to rotate, causing the transmission frame 41 to rotate the clamping mechanism 3 about an axis A extending along the second transverse direction Y.

[0044] Because the two side frames 411 of the transmission frame 41 are respectively connected to the pivot 42 and the actuating assembly 43, and the pivot 42 and the actuating assembly 43 are respectively arranged on the two support plates 21, the transmission frame 41 can be stably supported in the second lateral direction Y. Therefore, when the transmission frame 41 is driven by the actuating assembly 43, it can rotate smoothly around the axis A without shaking or tilting. In addition, because the two second cylinders 352 and the four second slide rail groups 351 are respectively arranged on the inner sides of the two side frames 411, the transmission frame 41 is equivalent to transmitting the rotational torque to the two side plates 331 of each pressure assembly 31, 31' through the second cylinders 352 and the second slide rail groups 351, thereby driving the clamping mechanism 3 to rotate. Therefore, the uniformity of the rotational torque transmitted to the clamping mechanism 3 can be improved, so that the clamping mechanism 3 can rotate smoothly around the axis A without shaking or tilting.

[0045] See Figure 1 In this embodiment, the pick-and-place device 30 is exemplified by a robotic arm. The pick-and-place device 30, for example, utilizes vacuum suction to hold the first surface 11 or the second surface 12 of the object under test 1 and can move the object under test 1. The pick-and-place device 30 is used to transfer the object under test 1 to the pressure plates 32a, 32b of the flipping device 20 and to remove the object under test 1 from the pressure plates 32a, 32b. Of course, the pick-and-place device 30 may also be another type of transfer device, not limited to a robotic arm. The pick-and-place device 30 may also utilize grippers to transfer the object under test 1, not limited to vacuum suction.

[0046] In this embodiment, the image capture device 40 is, for example, an area scan camera. Positioned above the clamping mechanism 3 of the flipping device 20 along the longitudinal direction Z, the image capture device 40 is configured to capture images of the first surface 11 or the second surface 12 of the object 1 under test. The captured images are then transmitted to an image processing device (not shown) for subsequent defect detection. Of course, the image capture device 40 may also be a line scan camera or other type of camera, and is not limited to an area scan camera.

[0047] The following describes in detail how the detection device 200 operates using the detection method of this embodiment:

[0048] Figure 7 1 is a flow chart of the detection steps of the detection method of this embodiment, including the following steps: step S1: placing the object to be detected and supporting the object to be detected, step S2: capturing an image of the first side of the object to be detected, step S3: changing the pressing plate to a closed state, step S4: changing the pressing assembly to a clamping state, step S5: rotating the pressing assembly, step S6: changing the pressing assembly to an open state, step S7: changing the pressing plate to an open state, step S8: capturing an image of the second side of the object to be detected, and step S9: removing the object to be detected.

[0049] See Figure 1 、 Figure 7 and Figure 8 In step S1, each pressing plate 32a of the pressing assembly 31 located at the bottom is in a closed position, so that the two pressing plates 32a are in a closed state. Each pressing plate 32b of the pressing assembly 31' located at the top is in an open position, so that the two pressing plates 32b are in an open state. The pick-up and placement device 30 adsorbs the first surface 11 of the object to be tested 1 by vacuum adsorption, and drives the object to be tested 1 to move toward the clamping mechanism 3 of the flipping device 20. Since the two pressing plates 32b of the upper pressing assembly 31' are in the open state, an opening 34 is defined between the two pressing plates 32b. Therefore, the pick-up and placement device 30 can drive the object to be tested 1 through the opening 34 and place the object to be tested 1 on the plate surface 325 of the two pressing plates 32a of the lower pressing assembly 31. Subsequently, the pick-up and placement device 30 will release the vacuum adsorption state and move away from the object to be tested 1 and the clamping mechanism 3 through the opening 34. At this time, the first surface 11 of the object 1 faces upward and corresponds to the opening 34 , and the second surface 12 of the object 1 faces downward and is supported by the plate surfaces 325 of the two pressing plates 32 a of the pressing assembly 31 .

[0050] See Figure 1 、 Figure 7 and Figure 9 In step S2, since the image capture device 40 is located above the clamping mechanism 3 along the longitudinal direction Z and corresponds to the position of the opening 34, the image capture device 40 can capture the image of the first surface 11 of the object to be tested 1 through the opening 34 and transmit the captured image to the image processing device for subsequent defect detection.

[0051] See Figure 6 、 Figure 7 and Figure 10 In step S3, the two first cylinders 337 of the upper pressure-pressing assembly 31' respectively drive the two connecting frames 336, causing the two connecting frames 336 to move the two pressure-pressing plates 32b in opposite directions along the first lateral direction X and toward each other, thereby moving each pressure-pressing plate 32b to a closed position. At this point, the inner plates 322 of the two pressure-pressing plates 32b abut against each other, causing the two pressure-pressing plates 32b to transition to a closed state. Because the two pressure-pressing plates 32b of the upper pressure-pressing assembly 31' are located a suitable distance above the first surface 11 of the object under test 1, the two pressure-pressing plates 32b will not contact or collide with the first surface 11 during movement, thereby causing damage to the first surface 11.

[0052] See Figure 2 、 Figure 7 and Figure 11In step S4, each second cylinder 352 of the drive assembly 35, via two actuating blocks 353, drives the two connected pressing assemblies 31 and 31' to move in opposite directions in the longitudinal direction Z and toward each other. When the plate surfaces 325 of the two pressing plates 32b of the pressing assembly 31' and the plate surfaces 325 of the two pressing plates 32a of the pressing assembly 31 respectively apply a predetermined pressure against the first surface 11 and second surface 12 of the object under test 1, each second cylinder 352 stops operating. At this point, the two pressing assemblies 31 and 31' transition from an open state, moving away from each other, to a clamped state, moving toward each other and clamping the object under test 1.

[0053] See Figure 1 、 Figure 7 and Figure 12 In step S5, the motor 431 of the actuating assembly 43 drives the transmission frame 41 to rotate via the transmission group 432, causing the transmission frame 41 to drive the clamping mechanism 3 to rotate about the axis A in a rotational direction R. During the rotation of the clamping mechanism 3, the two pressing assemblies 31 and 31' simultaneously drive the clamped object 1 to rotate. When the transmission frame 41 drives the clamping mechanism 3 to rotate 180 degrees in the rotational direction R, the motor 431 stops. At this point, the upper and lower positions of the two pressing assemblies 31 and 31' are swapped, so that the first surface 11 of the object 1 faces downward and the second surface 12 faces upward. Because the plate surface 325 of the pressing plate 32b of the pressing assembly 31′ and the plate surface 325 of the pressing plate 32a of the pressing assembly 31 respectively contact and press against the first surface 11 and the second surface 12 of the object under test 1 through surface contact, the stability of the object under test 1 when clamped can be effectively increased, and the stability of the pressing assemblies 31 and 31′ when driving the object under test 1 to rotate can be improved.

[0054] See Figure 2 、 Figure 7 and Figure 13 In step S6, each second cylinder 352 of the drive assembly 35, via two actuating blocks 353, drives the two connected pressing assemblies 31 and 31' to move in opposite directions in the longitudinal direction Z and away from each other, causing the two pressing assemblies 31 and 31' to transition from a clamped state to an open state, unclamping the object under test 1. At this point, the plate surfaces 325 of the two pressing plates 32a of the upper pressing assembly 31 move away from the second surface 12 of the object under test 1 and are positioned a suitable distance above it.

[0055] See Figure 4 、 Figure 7 and Figure 14In step S7, the two first cylinders 337 of the upper pressure-pressing assembly 31 respectively drive the two connecting frames 336, causing the two connecting frames 336 to move the two pressure-pressing plates 32a in opposite directions and away from each other along the first lateral direction X, thereby moving each pressure-pressing plate 32a to an open position. At this point, the two pressure-pressing plates 32a are in the open state, and the second surface 12 of the object under test 1 is aligned with the opening 34. Because the two pressure-pressing plates 32a of the upper pressure-pressing assembly 31 are positioned a suitable distance above the second surface 12 of the object under test 1, the two pressure-pressing plates 32a will not contact or collide with the second surface 12 during movement, thereby causing damage to the second surface 12.

[0056] See Figure 7 and Figure 14 In step S8, since the image capture device 40 corresponds to the position of the opening 34, the image capture device 40 can capture the image of the second surface 12 of the object 1 through the opening 34 and transmit the captured image to the image processing device for subsequent defect detection.

[0057] See Figure 7 and Figure 15 In step S9, the pick-up and placement device 30 passes through the opening 34 into the upper pressing assembly 31 and contacts the second surface 12 of the object to be tested 1. Then, the pick-up and placement device 30 adsorbs the second surface 12 of the object to be tested 1 by vacuum adsorption. Subsequently, the pick-up and placement device 30 drives the object to be tested 1 to move upward and move away from the clamping mechanism 3 (such as through the opening 34). Figure 1 ) to remove the object to be tested 1. At this point, the detection of the object to be tested 1 is completed.

[0058] Thereafter, steps S1 to S9 are repeated continuously to continuously perform image capturing and flipping operations on the remaining objects 1 to be tested.

[0059] It should be noted that, among the detection steps included in the detection method of this embodiment, as long as step S2 , step S8 and step S9 are omitted, the remaining steps are the flipping steps of the flipping device 20 using the flipping method of this embodiment.

[0060] In summary, the inspection device 200 of this embodiment, by disposing the image capture device 40 above the clamping mechanism 3 of the flipping device 20 along the longitudinal direction Z, can complete the image capture and flipping operations of the object to be tested 1 at a single workstation, saving the conveying equipment and transportation time required for transfer between two different workstations. Thus, the inspection speed and efficiency can be greatly improved, and the manufacturing cost of the inspection device 200 can be reduced. In addition, because the plate surfaces 325 of the two pressing plates 32b of the pressing assembly 31' and the plate surfaces 325 of the two pressing plates 32a of the pressing assembly 31 contact and press against the first surface 11 and the second surface 12 of the object to be tested 1 through surface contact, the stability of the clamping of the object to be tested 1 can be effectively increased, and the stability of the pressing assemblies 31 and 31' when driving the object to be tested 1 to rotate can be improved, thereby truly achieving the purpose of the present invention.
