[0042] The present utility model will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0043] This embodiment relates to a part inspection tooling, aiming to solve the problems of low efficiency and low accuracy in manual part inspection in the prior art, as well as the problems of poor image effect and low inspection accuracy in automatic part inspection.

[0044] In terms of the overall composition, the part inspection tooling includes a weighing unit, a lighting unit, and an image acquisition unit. Among them, the weighing unit includes a weighing part 2 and a supporting plate 201 provided on the weighing part 2, and at least part of the area of the supporting plate 201 is made of a transparent material. The lighting unit includes a first light source 4 located above the supporting plate 201 and a second light source 9 located below the supporting plate 201, and both the first light source 4 and the second light source 9 are used to illuminate the part to be inspected on the supporting plate 201; the image acquisition unit is located above the supporting plate 201 and is used to acquire an image of the part to be inspected.

[0045] For the part inspection tooling described in this embodiment, the weight of the part to be inspected is obtained through the weighing part 2, and the image of the part to be inspected is obtained by the image acquisition unit. Compared with the method of only obtaining images in the prior art, it is beneficial to improve the inspection accuracy of the part to be inspected. Also, at least part of the area of the supporting plate 201 is made of a transparent material, and the first light source 4 and the second light source 9 illuminate the part to be inspected above and below the supporting plate 201 respectively, which is beneficial to improving the image acquisition accuracy of the part to be inspected, and thus is beneficial to further improving the inspection accuracy of the part.

[0046] Based on the above overall introduction, an exemplary structure of the part inspection tooling described in this embodiment is as Figures 1 to 4As shown. The weighing unit, the lighting unit, and the image acquisition unit are all arranged in the box body 1. The box body 1 has a first cavity 100 in the middle, and a second cavity 200 located at the top of the box body 1 and communicating with the first cavity 100. A pick-and-place opening for the parts to be inspected to enter and exit is provided on one side of the first cavity 100. Among them, the weighing unit is arranged in the first cavity 100, and the first light source 4 and the image acquisition unit are arranged in the second cavity 200.

[0047] Here, the setting of the box body 1 is conducive to improving the protection of the weighing unit, the lighting unit, the image acquisition unit, etc. Arranging the first light source 4 and the image acquisition unit in the second cavity 200 is conducive to improving the lighting effect of the first light source 4 on the parts to be inspected, and thus conducive to improving the image acquisition accuracy. For the convenience of describing the following text, taking the Figure 1 viewpoint in as a reference, the side where the pick-and-place opening is located is called the outside, and the side opposite to the pick-and-place opening is called the inside. At the same time, the side on the left of the pick-and-place opening is called the left side, and the side on the right of the pick-and-place opening is called the right side.

[0048] As Figure 1 , Figure 4 and Figure 5 shown in, corresponding to the bottom of the pick-and-place opening, a support plate 105 is provided in the box body 1, and the above-mentioned weighing part 2 is arranged on the support plate 105. In specific implementation, the weighing part 2 can adopt products with weighing functions such as an electronic scale. In this embodiment, support blocks 203 are respectively provided at intervals at the bottoms of both sides of the supporting plate 201. The supporting plate 201 is specifically connected to the top of the weighing part 2 through the support blocks 203, and an installation space is formed between the supporting plate 201 and the weighing part 2. The second light source 9 is specifically located in the installation space.

[0049] Specifically, as Figure 5 shown in, the second light source 9 is installed on the support plate 105 through a support frame 106. The support frame 106 includes two columns located at both ends of the weighing part 2 and arranged at intervals, and a rod body passing through the installation space and connecting between the tops of the two columns on the same side. The above-mentioned second light source 9 includes lighting lamps arranged on the two rod bodies. Here, the lighting lamps are preferably plate-shaped, and the light-emitting surface faces the supporting plate 201.

[0050] The plate-shaped second light source 9 here is conducive to increasing the light-emitting area of the second light source 9, thereby improving the lighting effect on the parts to be inspected on the supporting plate 201. In addition, the whole of the supporting plate 201 is preferably made of a transparent material, and the specifications of the second light source 9 are preferably adapted to the specifications of the supporting plate 201 as much as possible to improve the lighting effect of the second light source 9 on the parts to be inspected as much as possible.

[0051] In specific implementation, the light-transmitting area of the supporting plate 201 is preferably made of transparent PC (abbreviation of Polycarbonate), so that the supporting plate 201 has high transparency and good light transmittance. Of course, it is also feasible that the whole of the supporting plate 201 is made of transparent material, or the main part of the supporting plate 201 is made of transparent material, and the part outside the main part is made of non-transparent material. At this time, it is only necessary to ensure that the light emitted by the second light source 9 can pass through the supporting plate 201 and irradiate on the part to be inspected.

[0052] As a preferred implementation manner, a supporting part is provided on the supporting plate 201, and the part to be inspected can be selectively placed on the supporting plate 201 or the supporting part. The supporting part includes a plurality of supporting members 202 arranged side by side on the supporting plate 201, and the distance between two adjacent supporting members 202 is adjustable. Here, the supporting plate 201 is mainly used to support the part to be inspected in the shape of the supporting plate 201, and the supporting part is used to support the part to be inspected with a curvature. Of course, the part to be inspected can also be placed on the supporting plate 201 and the supporting part, as long as it is ensured that the inspection surface of the part to be inspected in the placed state is in the target posture.

[0053] In this embodiment, by providing the supporting part, it can be arranged on the supporting plate 201 and the supporting part according to the structural characteristics and specifications of the parts, so as to facilitate meeting the placement requirements of different parts to be inspected. The distance between two adjacent supporting members 202 in the supporting part is adjustable, and different specifications of parts to be inspected can be supported, so it has good use flexibility.

[0054] As Figure 5 shown in, slide rails 2011 extending in the left-right direction are respectively provided on the inner and outer sides of the supporting plate 201, and sliders slidably arranged on the slide rails 2011 are respectively provided at both ends of each supporting member 202. By sliding the supporting member 202, the distance between the two supporting members 202 can be changed. Here, the cross section of the supporting member 202 is in a "U" shape, its structure is simple, it is convenient to arrange and implement, and the supporting effect is good. Of course, the supporting member 202 can also be in other shapes as long as the supporting requirements are met.

[0055] In addition, to improve the positioning effect of the part to be inspected on the supporting member 202, a positioning groove 2021 for positioning the part to be inspected is provided on at least one supporting member 202. The structure of the positioning groove 2021 is simple and the positioning effect is good. In terms of specific structure, as Figure 5As shown in the figure, a plurality of positioning grooves 2021 are respectively arranged on two opposite sides of each support member 202 at intervals along its own length. This is conducive to further improving the positioning points of the parts to be inspected on the support member 202, so as to meet the usage requirements of different parts to be inspected. Of course, in specific implementation, the scheme of arranging the positioning grooves 2021 only on one of the support members 202 and only on one side wall of the support member 202 is feasible.

[0056] In this embodiment, a support pin for supporting the part to be inspected can also be detachably arranged on at least one support member 202. The support pin and the support member 202 cooperate to achieve a better support effect on the part to be inspected. For example, a plurality of mounting holes 2022 are respectively arranged on the bottom wall of each support member 202 at intervals along its own length direction, and the support pin can be installed on the support member 202 through the mounting holes 2022. When the part to be inspected needs to be supported by the support pin, the support pin is installed in the corresponding mounting hole 2022 according to the usage requirements. When the part to be inspected does not need to be supported by the support pin, the support pin can be removed from the support member 202.

[0057] As a preferred implementation manner, in this embodiment, the lighting unit further includes a third light source 3 located on at least one side of the support plate 201. The third light source 3 is located above the side of the support plate 201 and is used to illuminate the part to be inspected on the support plate 201. By using the third light source 3 to perform supplementary lighting on the side, it is conducive to cooperating with the first light source 4 to improve the lighting effect on the part to be measured, and further conducive to improving the image acquisition accuracy of the image acquisition unit for the part to be measured.

[0058] As a feasible implementation manner, as Figure 1 and Figure 4 shown in the figure, the third light sources 3 are respectively arranged above the left and right sides of the support plate 201, so that there is a better lighting effect. Of course, the position of the third light source 3 can also be adjusted adaptively according to the usage requirements. The third light source 3 in this embodiment includes multiple groups of gratings 301 arranged at intervals up and down, and at least the height and light-emitting angle of one group of gratings 301 relative to the support plate 201 are adjustable. The light-emitting effect of the gratings 301 in the third light source 3 is good, and at least the height and light-emitting angle of one group of gratings 301 are adjustable, which is conducive to meeting the lighting requirements of parts to be inspected with different specifications and has better versatility.

[0059] In terms of the detailed structure, referring to Figure 4As shown in FIG. 1 , a plurality of vertical rods 101 are provided on the support plate 105 and are located on the left and right sides of the support plate 201. Each set of gratings 301 is installed on the vertical rods 101. Each set of gratings 301 is in the shape of a long strip and is extended along the width direction of the support plate 201. This is conducive to increasing the light output area of the gratings 301, and further to improving the lighting effect of the parts to be inspected. In order to facilitate the installation of the gratings 301 on the vertical rods 101, as shown in FIG. Figure 6 As shown in the figure, first connecting blocks 1011 are respectively provided on the two vertical rods 101 on the same side, and the first connecting blocks 1011 are provided with a first mounting hole for being mounted on the vertical rod 101, and a first notch connected to the first mounting hole. The first connecting blocks 1011 mounted on the vertical rod 101 are installed on the vertical rod 101 by threading bolts and nuts provided on both sides of the first notch, and a connecting rod 1012 is provided between the two first connecting blocks 1011 on the same side.

[0060] In addition, still refer to Figure 6 As shown in , a second connecting block 302 is respectively provided at both ends of the grating 301, and the second connecting block 302 is provided with a second mounting hole for being sleeved on the connecting rod 1012, and a second notch connected to the second mounting hole, and the second connecting block 302 sleeved on the connecting rod 1012 is installed on the connecting rod 1012 by screwing the bolts and nuts provided on both sides of the second notch. When in use, the height of the grating 301 relative to the supporting plate 201 can be adjusted by adjusting the position of the first connecting block 1011 on the vertical rod 101, and the light emitting angle of the grating 301 can be adjusted by rotating the second connecting block 302 relative to the connecting rod 1012, and the adjustment process of the entire grating 301 is simple and easy to operate. It should be noted that the number of gratings 301 in the third light source 3 on each side can also be adaptively increased or decreased, and the light emitting effect of each grating 301 can also be adjusted according to the use requirements.

[0061] As a preferred implementation, in this embodiment, Figure 7 As shown in the figure, a mounting seat 8 driven to rise and fall by a lifting mechanism is provided in the box body 1, and the image acquisition unit is provided on the mounting seat 8, and the height relative to the supporting plate 201 is adjusted along with the lifting and falling of the mounting seat 8. By arranging the image acquisition unit on the mounting seat 8, it is convenient to arrange and install the image acquisition unit, and by driving the mounting seat 8 to rise and fall by the lifting mechanism, it is convenient to adjust the height of the image acquisition unit relative to the supporting plate 201.

[0062] In terms of specific structure, the lifting mechanism in this embodiment includes a screw rod 7 disposed in the box body 1, and a rotation driving part connected to the screw rod 7. The mounting seat 8 is screwed on the screw rod 7, and the box body 1 is provided with a limiter for limiting the rotation of the mounting seat 8. Here, the structure of the screw rod 7 and the rotation driving part is simple, easy to arrange and implement, and the limiter limits the rotation of the mounting seat 8, which is conducive to improving the stability of the mounting seat 8 during lifting.

[0063] Reference Figure 7 and Figure 8 As shown in the figure, in this embodiment, a bottom plate 103 in a "U" shape and arranged along part of the circumference of the box body 1 is provided at the bottom of the first cavity 100, and the bottom end of the screw rod 7 is rotatably arranged on the bottom plate 103.

The screw rod 7 is arranged through the screw sleeve and is screwed to the screw sleeve. The limiting part includes a plurality of limiting rods 102 arranged at both ends of the bottom plate 103, and the limiting rods 102 are respectively arranged through the mounting seat 8.

[0064] A top plate 104 is provided above the bottom plate 103, and the top ends of the limit rods 102 are connected to the top plate 104, and the screw rod 7 is also rotatably provided on the top plate 104, which is conducive to further improving the stability of the limit rods 102 and the screw rod 7 in use. When the screw rod 7 rotates to drive the mounting seat 8 to move up and down, the limit rod 102 can prevent the mounting seat 8 from rotating, thereby guiding the mounting seat 8 to slide up and down along the height direction of the box body 1, thereby facilitating the change of the spacing between the image acquisition unit on the mounting seat 8 and the supporting plate 201.

[0065] like Figure 7 As shown in , the rotary drive unit in this embodiment includes a motor 6 disposed on the base plate 103, and the power output end of the motor 6 and the bottom end of the screw rod 7 are connected by a synchronous belt 601. The rotary driving force output by the motor 6 can be transmitted to the screw rod 7 through the synchronous belt 601, thereby driving the screw rod 7 to rotate, thereby making the height of the mounting seat 8 adjustable. In this embodiment, the way in which the motor 6 and the screw rod 7 cooperate is not only conducive to the arrangement and implementation, but also convenient for adjusting the height of the image acquisition unit and has high adjustment accuracy.

[0066] As a preferred embodiment, in this embodiment, a plurality of movable plates 801 are provided on the mounting seat 8, and the image acquisition unit includes a camera 5 provided on each movable plate 801. Among them, the position of at least one of the movable plates 801 on the mounting seat 8 is adjustable, and the position of at least one of the cameras 5 on the corresponding movable plate 801 is adjustable. Here, the position of the movable plate 801 on the mounting seat 8 and the position of the camera 5 on the movable plate 801 are adjustable, which are both conducive to adjusting the position of the camera 5, thereby having better flexibility of use. In addition, the cooperation of multiple cameras 5 is conducive to improving the comprehensiveness and accuracy of image acquisition.

[0067] As a preferred embodiment, the position of each movable plate 801 on the mounting base 8 is adjustable, which is conducive to further improving the flexibility of adjusting the position of the camera 5 on the movable plate 801.

The two moving plates 801 are arranged at intervals in the front - rear direction of the supporting plate 201 and are connected between the left and right sides of the mounting base 8. Both moving plates 801 can move in the front - rear direction of the mounting base 8. Specifically, when implemented, first long slots 802 extending in the front - rear direction are respectively provided on both sides of the mounting base 8. At both ends of each moving plate 801, first pin shafts 8012 slidably arranged in the corresponding first long slots 802 are respectively connected.

By sliding the mounting brackets 501, the positions of the second pin shafts 5011 in the second long slots 8011 are adjusted until the camera 5 is moved to the target position. Here, the adjustment method of the position of the camera 5 on the moving plate 801 is simple and easy to operate. Of course, the number of cameras 5 with adjustable positions on the moving plate 801 can also be determined according to the usage requirements.

[0071] When the part inspection tooling described in this embodiment is in use, it is necessary to first adjust the spacing between the support members 202 according to the specifications and shapes of the parts to be inspected, and whether support pins need to be installed on the support members 202. Then, adjust the height of each grating 301 to the target height, and adjust the light-emitting angle of the grating 301 to the target angle. Then, start the motor 6 to adjust the first light source 4 and the camera 5 on the mounting base 8 to the target height. Next, adjust the positions of the moving plates 801 and the position of the camera 5 on the moving plate 801 until each camera 5 is adjusted to the target position.

[0072] Then, place the part to be inspected on the supporting plate 201 or the support member 202. The weighing unit 2 obtains the weight of the part to be inspected, and the camera 5 in the image acquisition unit obtains the image of the part to be inspected. This is conducive to using the weight and the image as the basis for inspecting whether the part to be inspected is qualified, thereby facilitating the improvement of inspection accuracy.

[0073] In addition, in this embodiment, an electronic control unit can also be provided at the bottom of the box body 1. The electronic control unit includes a receiving module for receiving the information of the weighing unit 2 and the image acquisition unit, a storage module storing various part weight information and image information, and a comparison module for comparing the received information with the corresponding stored information and outputting a comparison result. Here, the electronic control unit can refer to the existing technology. For example, it can use a PLC programmable controller, etc. In addition, a display 10 for displaying the comparison result and a bar code scanner for identifying the part to be inspected can also be provided on the box body 1 to facilitate the improvement of inspection efficiency.

[0074] The part inspection tooling of this embodiment obtains the weight of the part to be inspected through the weighing unit 2. The first light source 4, the second light source 9, and the third light source 3 cooperate to improve the lighting effect on the part to be inspected, which is conducive to improving the accuracy of the image acquired by the image acquisition unit. It also further improves the image acquisition accuracy through the cooperation of multiple cameras 5, thereby facilitating the improvement of inspection accuracy and inspection efficiency.

[0075] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
