Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, specifically to a multi-faceted testing device. Background Technology

[0002] Currently, when inspecting electronic products or other workpieces, in order to ensure more accurate inspection results, it is necessary to use a camera to take pictures of multiple external surfaces of the workpiece, such as the side and top surfaces.

[0003] Therefore, the detection camera needs to have the function of moving in multiple directions, and the structure of the moving parts of the camera is often quite complex.

[0004] A solution using a robotic arm to drive a camera for inspection has been publicly disclosed. However, in existing technologies, robotic arms are relatively expensive due to the multi-dimensional movement control requirements. Therefore, directly using a robotic arm to inspect camera movement cannot meet the market's demand for reducing the cost of inspection equipment. Utility Model Content

[0005] To overcome the above-mentioned shortcomings, the purpose of this utility model is to provide a multi-faceted inspection device.

[0006] This utility model's multi-faceted inspection device includes a workpiece carrier and an inspection unit. At least one workpiece stage is mounted on the workpiece carrier. The inspection unit has a corresponding inspection camera for each workpiece stage, and all inspection cameras are mounted on a mounting plate. The device also includes a moving part for moving the inspection cameras. The moving part includes a first swing member, a second swing member, and a third swing member that are rotatably connected to each other in sequence. The first swing member is connected to a fixing mechanism and includes a mounting base mounted on the fixing mechanism. The first swing member has a first drive source and is mounted on the mounting base. A second drive source is located at the end of the second swing member connected to the first swing member, and a third drive source is located at the end of the third swing member connected to the second swing member.

[0007] It also includes a connecting plate for setting the workpiece stage, the connecting plate being movable in the front-back direction and the left-right direction.

[0008] This application has the following beneficial effects:

[0009] ① By setting the moving part as a first swing member, a second swing member, and a third swing member that are rotatably connected to each other in sequence, and setting a drive source corresponding to each swing member, the movement of each swing member is controlled by only one drive source. That is, only three independent motors are needed to control the movement of one swing member. Therefore, the performance requirements and setting complexity of the control system and drive system are greatly reduced. This application replaces the existing method of using a robot arm to move the detection camera, which greatly reduces the cost of using the moving part.

[0010] ② By setting a connecting plate that can move the workpiece stage back and forth and left and right, before inspection, the workpiece stage is moved closer to the inspection camera by the connecting plate. Therefore, the size requirements of the swinging part of the moving part are further reduced, making the processing and use cost of the moving part lower.

[0011] Furthermore, the movable part includes a first swing member, a second swing member, and a third swing member that are rotatably connected to each other in sequence. The first swing member is connected to the fixed mechanism and also includes a mounting base disposed on the fixed mechanism. The first swing member has a first drive source and is disposed on the mounting base. Therefore, the movable part can be entirely mounted on the fixed mechanism via the mounting base. That is, during the movement of the movable part, only the mounting base portion forms a large force point on the fixed mechanism, thus effectively reducing the shaking of the entire device when adjusting the angle of the detection camera.

[0012] Furthermore, a second drive source is provided at the end of the second swing member that is connected to the first swing member, and a third drive source is provided at the end of the third swing member that is connected to the second swing member.

[0013] Furthermore, the first, second, and third drive sources are all motors, and the motor shafts of the three drive sources are arranged in a direction perpendicular to the first, second, and third swinging components. Therefore, the detection camera can move forward and backward, and up and down, towards the workpiece, and can swing the workpiece within a fan-shaped space to the front and rear.

[0014] Furthermore, the workpiece stage rotates under the action of a rotary drive mechanism, which includes a rotary drive source and a drive shaft that rotates under the action of the rotary drive source.

[0015] Furthermore, the drive shaft can simultaneously drive each of the workpiece platforms to rotate, and the workpiece platforms are connected to each other via connecting shafts.

[0016] Furthermore, the rotation axis of the workpiece stage is not coplanar with the rotation axis of the drive shaft.

[0017] Furthermore, it also includes at least one transmission gear set connected to the drive shaft or connecting shaft. Each transmission gear set includes a first gear connected to the drive shaft or connecting shaft and a second gear coaxially connected to the workpiece stage. The axes of the first gear and the second gear are not coplanar. Therefore, it improves the transmission stability when outputting power to the workpiece stage and increases the output torque to the workpiece stage.

[0018] Furthermore, it also includes a connecting plate for setting the workpiece stage, the connecting plate being movable in the front-back direction and the left-right direction.

[0019] Furthermore, the positions of each of the detection cameras on the mounting plate are adjustable, and the system also includes a camera mounting base and an adjusting screw passing through the camera mounting base. A fixing plate is provided on the mounting plate, and the adjusting screw is rotatably mounted on the fixing plate. Therefore, by adjusting the adjusting screw, the position of each detection camera can be individually adjusted slightly when multiple detection cameras are set up, which can meet the accuracy requirements for simultaneous detection of multiple samples by multiple detection cameras.

[0031] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0032] See appendix Figure 1-6 As shown, the multi-faceted inspection device of this utility model includes a workpiece carrier and an inspection unit 2. Multiple rotatable workpiece platforms 11 are mounted on the workpiece carrier. The inspection unit 2 has a corresponding inspection camera 22 for each workpiece platform 11, and all inspection cameras 22 are mounted on a mounting plate 21. The multi-faceted inspection device of this utility model also includes a moving part 3 for swinging the inspection cameras 22 back-to-back, up-down, and front-to-back sides. The inspection unit 2 can capture images of the front and rear sides of the workpiece under the action of the moving part 3. The moving part 3 is connected to the mounting plate 21; therefore, by moving the mounting plate 21 alone, the synchronous movement of each inspection camera 22 above and on both sides of the workpiece can be achieved in batches. The rotation direction of the workpiece platform 11 is different from the movement direction of the inspection camera 22 driven by the moving part 3. Figure 1 Taking this as an example, the rotation direction of the workpiece stage 11 is... Figure 1 The direction of movement of the moving part 1 towards the detection camera 22 is as follows, indicated by the middle arrow A. Figure 1 The direction of the middle arrow B.

[0033] See appendix Figure 6 As shown, the multi-faceted inspection device also includes a connecting plate 12 for setting the workpiece stage 11. The connecting plate 12 is movable in the front-back and left-right directions. The connecting plate 12 is mounted on the slide plate 14 via a first slide rail assembly 13, and is driven by a drive source (such as a motor) to move along the slide rail of the first slide rail assembly 13. The slide plate 14 is connected to the slider of the second slide rail assembly 15 and moves under the drive of the second slide rail assembly 15. The sliding directions of the first slide rail assembly 13 and the second slide rail assembly 15 are perpendicular to each other. For example, the sliding direction of the first slide rail assembly 13 is... Figure 6The first slide rail is in the left-right direction, and the second slide rail assembly 15 is in the front-back direction. Therefore, the connecting plate 12 can move each workpiece stage 11 in the front-back and left-back directions. After the connecting plate 12 moves the workpiece stage 11 to the most suitable position for the inspection camera to capture images, the position of the connecting plate 12 remains stationary.

[0034] This application replaces the existing method of using a robotic arm to move the inspection camera. It only requires three independent motors to control the movement of a single swinging component, thus greatly reducing the performance requirements and setup complexity of the control and drive systems, and significantly lowering the cost of the moving part. When inspecting products of different sizes, the relative positions of the inspection camera and the workpiece stage 11 in the front-back direction vary. If relying solely on the moving part 3 of this application, the length of the swinging component of the moving part 3 should be as small as possible to minimize the performance requirements of its drive source. However, this may limit the forward-backward movement distance of the moving part, hindering sufficient image capture. Therefore, this application first pre-adjusts each workpiece stage 11 to a suitable position in the front-back and left-right directions using the connecting plate 12 before inspection. During inspection, the workpiece stage 11 rotates, and the moving part 3 drives each inspection camera to swing. Therefore, by pre-adjusting the workpiece position through the connecting plate 12 that can move forward, backward, left, and right, the movement range of each swinging component of the moving part 3 is smaller, and the size requirements are also lower, thereby reducing the weight and size of the moving part 3 by a greater extent, and thus effectively reducing the cost of the moving part.

[0035] In some implementations, in conjunction with the appendix Figure 2 As shown, this multi-faceted inspection device also includes a camera mounting base 23 and an adjusting screw 24 passing through the camera mounting base 23. A fixed plate 25 is provided on the mounting plate 21, and the adjusting screw 24 is rotatably mounted on the fixed plate 25. Therefore, by rotating the adjusting screw 24, the position of each inspection camera 22 on the mounting plate 21 can be adjusted. The upper end of the fixed plate 25 has a connecting plate 26 extending towards the inspection 22 side, and the adjusting screw is located at the connecting plate 26. With this structure, the structural components required for adjusting the inspection cameras 22 are minimized to the greatest extent. Moreover, by mounting each inspection camera 22 on the mounting plate 21 through a camera mounting base 23, the position of each inspection camera 22 can be individually adjusted slightly when multiple inspection cameras 22 are set up, which can meet the requirement of simultaneously setting up multiple inspection cameras 22 to inspect multiple samples.

[0036] In some implementations, in conjunction with the appendix Figure 3As shown, the moving part 3 includes a first swing member 31, a second swing member 32, and a third swing member 33 that are rotatably connected to each other in sequence. The first swing member 31 is rotatably connected to a fixed mechanism (which can be a machine base, or a fixed frame or mounting frame installed on the machine base). The third swing member 33 is connected to the mounting plate 21, and the third swing member 33 is located at the end away from the fixed mechanism. The three swing members enable the taking of pictures and inspecting the front and rear sides of the workpiece. Furthermore, this application incorporates a rotatable workpiece stage 11, thus enabling the taking of pictures of the entire side wall area and top of the workpiece. This application utilizes only a three-axis moving part combined with the rotatable function of the workpiece stage 11 to satisfy the inspection of any area of ​​the top and side surfaces of the workpiece, while maximizing the simplification of the moving part's structural setup. Simultaneously, by mounting each inspection camera 22 on the mounting plate 21, the position of each inspection camera 22 can be adjusted in batches simply by moving the mounting plate 21, enabling rapid picture inspection of batches of products. Furthermore, since the moving part is not attached to the function of rotating along the axial direction of the detection camera 22, the weight of the robot arm itself is reduced to the greatest extent possible, and the shaking during the movement of the moving part is also reduced.

[0037] In some embodiments, the first swing member 31 has a first drive source 35, and the first swing member 31 is disposed on the mounting base 34, with the first drive source 35 located at the end away from the second swing member 32. Therefore, the moving part 3 can be entirely mounted on the fixed mechanism via the mounting base 34. That is, during the movement of the moving part 3, only the mounting base 34 forms a large force point on the fixed mechanism, thus effectively reducing the shaking of the entire device when adjusting the angle of the detection camera 22.

[0038] A second drive source 36 is provided at the end of the second swing member 32 that connects to the first swing member 31, and a third drive source 37 is provided at the end of the third swing member 33 that connects to the second swing member 32. The first drive source 35, the second drive source 36, and the third drive source 37 are all motors, and the motor shafts of the three drive sources are arranged in a direction perpendicular to the first swing member 31, the second swing member 32, and the third swing member 33. This allows the detection camera 22 to swing back and forth and up and down in a direction closer to or further away from the workpiece.

[0039] In some implementations, see Appendix Figure 4 As shown, the workpiece platform 11 rotates under the action of the rotary drive mechanism, which includes a rotary drive source 41 and a drive shaft 42 that rotates under the action of the rotary drive source 41.

[0040] The drive shaft can simultaneously drive each workpiece platform 11 to rotate. The workpiece platforms 11 are connected by connecting shafts 43, and adjacent connecting shafts 43 are connected by couplings. Thus, synchronous transmission of each workpiece platform 11 can be achieved.

[0041] In some implementations, see Appendix Figure 5 As shown, the multi-faceted inspection device also includes at least one transmission gear set connected to the drive shaft 42 or the connecting shaft 43. Each transmission gear set includes a first helical gear 44 connected to the drive shaft 42 or the connecting shaft 43 near the input end of the rotary drive source 41, and a second helical gear 45 coaxially connected to the workpiece stage 11. The second helical gear 45 has a larger number of teeth than the first helical gear 44, and the second helical gear 45 is located on the side of the first helical gear 44 in the axial direction. The first helical gear 44 is coaxially connected to the connecting shaft 43 and connected to the connecting shaft 43 corresponding to another workpiece stage via a coupling. By making the axis of the second helical gear 45 not in the same plane as the axis of the first helical gear 44, this application can achieve the effect of compact transmission between the first helical gear 44 and the second helical gear 45, and also allow the workpiece stage 11 to output a larger torque.

[0042] In some embodiments, a guide plate 16 is also included, which is disposed along the moving direction of the second slide rail assembly 15 and passes through the hollow area in the middle of the slide plate 14.

[0043] This application also includes a gantry 51 for mounting the mounting base 34, which is mounted on the machine base 52. This ensures that the moving part 3 does not cause the entire machine base 52 to shake during the movement of the inspection camera 22.

[0044] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They cannot be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
