[0033] The first embodiment

[0034] The present utility model provides a device for collecting the surface image of a stamping part. The stamping part is located on a conveying mechanism, and a collecting platform is provided on the conveying mechanism. Loading brackets are provided on both sides of the collecting platform, and the collecting device is located on the loading brackets; an image collector 6 is provided on the collecting device. The collecting device includes:

[0035] Two mutually parallel tracks 1 fixed on the loading brackets;

[0036] A crossbeam 2 lying across the two tracks 1 and perpendicular to the tracks 1; sliders are respectively provided at the lower end of the crossbeam 2 corresponding to the two tracks 1.

[0037] A number of electronically controlled moving rods 3 connected to the lower end of the crossbeam 2; the electronically controlled moving rods 3 are symmetrically arranged at both ends of the crossbeam 2 respectively.

[0038] Exemplarily, the image collector 6 can be a CCD camera, a flat scanner, an industrial camera, etc.; the industrial camera can transmit the captured image information to a computer terminal through a wired or wireless transmission method for relevant data processing. This part of the content is prior art and will not be elaborated here; in addition, the number of image collectors is not specifically limited and shall be subject to actual requirements.

[0039] For the mutually parallel tracks 1, a drag chain 4 is provided beside one of the tracks 1. The drag chain 4 is fixed to one end of the crossbeam 2. The drag chain 4 can be driven by a motor, and the slider can slide in the track. Therefore, the drag chain 4 can drive the crossbeam 2 to move on the track 1 and will also drive the electronically controlled moving rods 3 to perform a horizontal displacement.

[0040] Here, there is no requirement for the length of the track, and it only needs to meet the actual requirements; running on the two mutually parallel tracks 1 can ensure the stability of the whole device during the displacement process; among them, the direction of the track 1 can be perpendicular or parallel to the transportation direction of the conveying mechanism, and the position of the crossbeam 2 can be adjusted correspondingly according to the position of the stamping part.

[0041] The electric control movable rod 3 can be lifted automatically. If an image collector is connected to the bottom end of the electric control movable rod 3, the height of the electric control movable rod 3 can be adjusted to meet the height requirements of the image collector.

[0042] In this application, the number of the electric control movable rods 3 is not limited, as long as the collection requirements are met.

[0043] Second Embodiment

[0044] Based on the content of the foregoing embodiment, further optimization is carried out:

[0045] The electric control movable rods 3 are connected by a cross bar 5, and the same lifting operation is carried out simultaneously to form an integral structure, which increases the stability of the structure and ensures the stability of lifting; the image collector 6 here can also be arranged on the cross bar 5, and the stability is better.

[0046] The lengths of the electric control movable rods 3 can be set to be not all the same to meet the requirements of camera collection at different heights and angles;

[0047] An extension piece 7 is fixed on the cross beam 2, and the extension piece 7 is connected to the electric control movable rod 3 by threads. The extension piece 7 can be an angle steel with holes and is fixed on the cross beam 2 by welding or screwing;

[0048] A vertical rod 8 can also be connected to the extension piece 7 by threads, and the vertical rod 8 and the electric control movable rod 2 are connected by a cross bar 5, further enhancing the stability of the device.

[0049] This application can also be provided with a control mechanism for controlling the operating states of the motor and the electric control movable rod; the control mechanism can be a PLC controller, which can directly judge the position of the camera according to the acquired image situation, and thus issue a displacement instruction to realize the unified control of the horizontal displacement and the vertical displacement.

[0050] In addition, the requirements for the light source, environment, etc. during the image capture process can all be met by the existing technology, and no further description is given here.

[0051] In this application, the track 1 of the collection device can be perpendicular to the transportation direction of the conveying mechanism, as Figure 2 shown, two collection devices can be arranged simultaneously, increasing the image information of the surface of the stamping part that can be obtained simultaneously.

[0052] Third Embodiment

[0053] Based on the content of the foregoing embodiment, when the stamping part is located below the collection device, the position of the image collector 6 of the collection device is adjusted accordingly to collect images at different positions;

[0054] The stamping part surface image acquisition device realizes collaborative work by controlling the position of the cross beam 2 and the lifting of the electric control moving rod 3, and accurately acquires the image of the upper surface of the stamping part.

[0055] The control mechanism can adjust the position and angle of the image collector 6 in real time according to the preset program or the operator's instructions to ensure that the acquired image is clear and accurate.

[0056] Based on the above technical solution, through the collaborative work of the cross beam and the electric control moving rod, the accurate acquisition of the image of the upper surface of the stamping part is realized; while ensuring the stability during displacement and shooting, the clarity of the image acquisition is improved, and the accuracy and reliability of the detection result are ensured.

[0057] The above is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
