Description

Technical Field

[0001] This utility model relates to the field of parts inspection, and in particular to a non-contact inspection device. Background Technology

[0002] With the development of technology, more and more precision infusion devices have emerged in the medical field. These precision infusion devices typically include special-shaped parts with leads, which also include functional components fixedly connected to the leads. For example, invention patent CN115625510A discloses a special-shaped lead assembly, including a first contact piece, a spring piece, and a second contact piece connected in sequence by the leads. Existing testing devices often require direct clamping of the parts using fixtures or other components. If this type of testing device is used for contact testing, it may cause physical damage to the leads and connecting components, leading to part deformation, surface scratches, or even functional failure, affecting product quality. Furthermore, since the special-shaped parts include leads, to enable comprehensive visual inspection of the leads, the leads should ideally be kept straight during visual inspection.

[0003] In view of this, the present invention proposes a non-contact detection device to solve the above problems. Summary of the Invention

[0004] In order to overcome the shortcomings of the above-mentioned technology, this utility model provides a non-contact inspection device that can straighten the wires of special parts and visually inspect the appearance of special parts, while avoiding direct contact that could damage the special parts.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A non-contact inspection device is disclosed for inspecting special-shaped parts, the special-shaped parts including a wire and a first component fixedly connected to both ends of the wire. The non-contact inspection device includes a worktable, on which two first fixed seats, a tensioning mechanism, and a vision inspection mechanism are provided. Each of the two first fixed seats has a first workpiece recess for placing the first component. The tensioning mechanism is used to move the two first fixed seats to straighten the wire. The vision inspection mechanism is used to inspect the appearance of the special-shaped part after the wire is straightened.

[0007] Preferably, the tensioning mechanism includes a first slide rail extending along the X-axis and two first slide cylinders connected to the first slide rail, with the two first slide cylinders respectively drivingly connected to two first fixed seats.

[0008] Preferably, the tensioning mechanism includes a tension spring extending along the X-axis, one end of which is connected to a first fixed seat, and the other end of which is fixedly connected to a first slide cylinder via a connecting assembly.

[0009] Preferably, if the special part further includes a second component fixedly connected to the wire, the second component is located between the two first components; the worktable is provided with a second fixing seat, the second fixing seat is provided with a second workpiece recess for placing the second component.

[0010] Preferably, the non-contact detection device further includes a tension calibration mechanism for measuring the force on the second fixed seat along the X-axis direction. The tension calibration mechanism includes an extension component fixedly connected to the second fixed seat and two opposing force gauges, with the force hooks of the two force gauges fixedly connected to the extension component.

[0011] Preferably, the workbench is provided with a Y-axis linear module, and the output end of the Y-axis linear module is fixedly connected to a moving platform. The tensioning mechanism, the first fixed seat, the second fixed seat, and the tension calibration mechanism are all installed on the moving platform. The Y-axis linear module is used to move the moving platform along the Y-axis direction to below the vision inspection mechanism.

[0012] Preferably, the mobile platform is provided with two second slide rails extending along the X-axis direction, each second slide rail is connected to a slider that can slide on the second slide rail, and the slider is fixedly connected to the first fixed seat.

[0013] Preferably, the visual inspection mechanism is a CCD visual inspection mechanism, including an X-axis linear module, the output end of which is fixedly connected to a bracket, and a camera is mounted on the bracket.

[0014] Preferably, the bracket is provided with a second slide cylinder 54 for driving the camera to move along the Z-axis.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. The first workpiece recess on the two first fixed seats of this utility model is used to place the first components at both ends of the special part, avoiding the risk of surface scratches caused by rigid contact with the special part; at the same time, the tensioning mechanism drives the first fixed seat to move and straighten the wire, so that the visual inspection mechanism can capture the appearance features of the wire and the entire special part more comprehensively and clearly, solving the problem that the wire cannot be fully inspected due to bending.

[0017] 2. The tensioning mechanism includes a first slide cylinder for driving the first fixed seat to move along the X-axis. The first slide cylinder is connected to the first fixed seat through a tension spring. When the first slide cylinder drives the first fixed seat to move, the tension spring can provide a buffering force to prevent the rigid drive of the first slide cylinder from directly acting on the first fixed seat and the wire, and to prevent the wire from being pulled off or damaged due to excessive instantaneous force.

[0018] 3. The second component of the special part is placed on the second fixed seat. The tension calibration mechanism can measure the force on the second fixed seat along the X-axis, thereby determining whether the special part is under balanced force along the X-axis. If the force is unbalanced, the distance between the two first fixed seats is further adjusted by the tensioning mechanism to balance the force on the special part, thus avoiding damage to the special part due to unbalanced force.

[0023] The implementation, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0024] The following examples provide a more detailed description of the features and other related characteristics of this utility model, to facilitate understanding by those skilled in the art:

[0025] Reference Figures 1-4 This utility model provides an embodiment of a non-contact detection device.

[0026] A non-contact inspection device for inspecting special-shaped parts 1, such as... Figure 2 As shown, the special part 1 includes a wire 11 and first components 12 fixedly connected to both ends of the wire 11. The non-contact inspection device includes a worktable 2, on which two first fixed seats 3, a tensioning mechanism 4, and a vision inspection mechanism 5 are provided. Each of the two first fixed seats 3 is provided with a first workpiece recess 31. The first components 12 at both ends of the special part 1 are respectively placed on the first workpiece recess 31 to avoid the risk of surface scratches caused by rigid contact with the special part 1.

[0027] The tensioning mechanism 4 is used to move the two first fixed seats 3 so that the wire 11 is straightened; the visual inspection mechanism 5 is used to inspect the appearance of the special part 1 after the wire 11 is straightened. The visual inspection mechanism 5 can capture the appearance features of the wire 11 and the entire special part 1 more comprehensively and clearly, solving the problem that the wire 11 cannot be fully inspected due to bending.

[0028] like Figure 4 As shown, the tensioning mechanism 4 includes a first slide rail 41 extending along the X-axis direction and two first slide cylinders 42 connected to the first slide rail 41. The two first slide cylinders 42 are respectively connected to two first fixed seats 3.

[0029] The tensioning mechanism 4 includes a tension spring 43 extending along the X-axis. One end of the tension spring 43 is connected to the first fixed seat 3, and the other end of the tension spring 43 is fixedly connected to the first slide cylinder 42 via a connecting assembly. When the first slide cylinder 42 drives the first fixed seat 3 to move, the tension spring 43 provides a buffering force to prevent the rigid drive of the first slide cylinder 42 from directly acting on the first fixed seat 3 and the wire 11, thus preventing the wire 11 from being pulled apart or damaged due to excessive instantaneous force.

[0030] like Figure 3 As shown, the connecting assembly includes a connecting seat 421 fixedly connected to the top of the first slide cylinder 42, a first connecting plate 422 fixedly connected to the top of the connecting seat 421, and a second connecting plate 423 fixedly connected to the top of the first connecting plate 422. A connector 424 is connected to the portion of the second connecting plate 423 protruding outside the first connecting plate 422. The connector 424 has a first pin 425 for connecting to one end of the tension spring 43. The first fixed seat 3 has a second pin 32 for connecting to the other end of the tension spring 43.

[0031] like Figure 2 As shown, if the special part 1 further includes a second component 13 fixedly connected to the wire 11, the second component 13 is located between the two first components 12; the worktable 2 is provided with a second fixed seat 33, and the second fixed seat 33 is provided with a second workpiece recess for placing the second component 13.

[0032] The non-contact detection device also includes a tension calibration mechanism for measuring the force on the second fixed base 33 along the X-axis. The tension calibration mechanism includes an extension component 61 fixedly connected to the second fixed base 33 and two opposing force gauges 6. The force measuring hooks of the two force gauges 6 are fixedly connected to the extension component 61.

[0033] Specifically, the extension component 61 extends along the Y-axis direction, and the worktable 2 is provided with a lifting cylinder 62 below the extension component 61 to support the extension component 61 and balance the force in the Z-axis direction.

[0034] When the readings of the two force gauges 6 are the same, the special part 1 is in force balance. When one of the force gauges reads a larger value, it indicates that before the force measurement, the side of special part 1 with the smaller reading experienced a greater force. While the force gauges are monitoring the force on special part 1, a reaction force can be applied to it to balance the force on special part 1.

[0035] Specifically, the housing 63 of the force gauge 6 is fixed to the second connecting plate 423 via the third connecting plate 426.

[0036] like Figure 2 As shown, the workbench 2 is equipped with a Y-axis linear module 7. The output end of the Y-axis linear module 7 is fixedly connected to a moving platform 71. The tensioning mechanism 4, the first fixed seat 3, the second fixed seat 33, and the tension calibration mechanism are all installed on the moving platform 71. The Y-axis linear module 7 is used to move the moving platform 71 along the Y-axis direction to below the vision inspection mechanism 5.

[0037] The mobile platform 71 is provided with two second slide rails 72 extending along the X-axis. Each second slide rail 72 is connected to a slider 73 that can slide on the second slide rail 72. The slider 73 is fixedly connected to the first fixed seat 3. When the slider 73 cooperates with the second slide rail 72, the movement of the first fixed seat 3 driven by the first slide cylinder 42 is more stable.

[0038] like Figure 3 As shown, the vision inspection mechanism 5 is a CCD vision inspection mechanism, which can achieve a vision inspection accuracy of ±0.005mm for special-shaped parts 1. It includes an X-axis linear module 51, the output end of which is fixedly connected to a bracket 52, on which a camera 53 is mounted. The X-axis linear module 51 can drive the vision inspection mechanism 5 to move along the X-axis direction to accommodate special-shaped parts 1 of different lengths.

[0039] The bracket 52 is equipped with a second slide cylinder 54 for driving the camera 53 to move along the Z-axis. This allows the camera 53 to be raised and lowered to adjust its field of view.

[0040] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the contents of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
