[0025] To further understand the features, technical means, specific purposes and functions achieved by the present utility model, the present utility model will be further described in detail below in conjunction with the drawings and specific implementation manners.

[0026] Refer to Figures 1-8 : A movable light source bracket, including a mounting base 101 and a support frame 102 provided on the mounting base 101. The support frame 102 is used to mount a light source. The support frame 102 is provided with a plurality of shifting pieces 104 that cooperate with the retaining pieces 103 on the conveyor belt. The shifting pieces 104 are used to drive the support frame 102 to perform a relative static movement with the product along the material conveying direction. The mounting base 101 is provided with a control mechanism, and the control mechanism is used to drive the shifting piece 104 to avoid the retaining piece 103 when the support frame 102 moves to the end of the mounting base 101. The mounting base 101 is also provided with a first return spring 110 for driving the support frame 102 to perform a reset movement in the opposite direction of the material conveying.

[0027] The mounting seat 101 is used to support the sliding of the support frame 102, and the support frame 102 is used to install the light source. The light source is used to provide light for the product, so that the detection camera can take pictures of the product and distinguish qualified products from unqualified products. The conveyor belt places several products in sequence, and a baffle 103 is provided on one side of the product on the conveyor belt. When the conveyor belt moves, the baffle 103 is driven to move. The mounting seat 101 is provided with a support frame 102 for sliding. The mounting seat 101 is provided with a receiving groove on the side close to the conveyor belt, and the support frame 102 is provided with a paddle 104 on the side close to the conveyor belt. One end of the paddle 104 is slidably matched with the receiving groove When the baffle 103 encounters the paddle 104, it drives the paddle 104 to perform relative static movement with the product. When the paddle 104 moves to the end of the mounting seat 101, it triggers the control component to drive the paddle 104 to avoid the baffle 103. The first reset spring 110 drives the support frame 102 to reset. At this time, the control component drives the paddle 104 to reset, and continues to drive the paddle 104 to reciprocate through the next baffle 103. In this way, the light source can move with the product, provide light source for the product, and facilitate the detection camera to take pictures of the product, thereby improving the quality of product detection.

[0028] Reference Figures 3-8 : The control mechanism includes a trigger plate 105, a resistance block 106, a pulling rope 107, a second reset spring and a third reset spring; the trigger plate 105 is installed at the end of the mounting seat 101; the resistance block 106 is slidably arranged inside the support frame 102 and cooperates with the trigger plate 105, and the support frame 102 is provided with a second reset spring for driving the resistance block 106 to reset in the opposite direction of the feeding when the support frame performs a reset movement in the opposite direction of the feeding; one end of the pulling rope 107 is connected to the resistance block 106, and the other end is connected to the paddle 104, and the support frame 102 is provided with a third reset spring for driving the paddle 104 to reset in the direction away from the conveyor belt.

[0029] When the paddle 104 moves to the end of the mounting base 101, the contact block 106 slidably arranged on the side of the support frame 101 close to the end of the mounting base 101 contacts the trigger plate 105. The trigger plate 105 pushes against the contact block 106, causing the contact block 106 to retract, driving the pulling rope 107 to move. The pulling rope 107 drives the paddle 104 to retract and unlock from the retaining piece 103. At this time, the first return spring drives the support frame 102 to reset, the second return spring drives the contact block 106 to reset, and the third return spring drives the paddle 104 to reset and cooperate with the next retaining piece 103. The distance between the trigger plate 105 and the contact block 106 can be adjusted by the length of the bolt-mounted trigger plate 105. When the first return spring 110 is used for a long time, it is necessary to continuously reduce the distance between the trigger plate 105 and the contact block 106 to trigger the contact block 106 to drive the pulling rope 107 to move, so that the retaining piece 103 and the paddle 104 are unlocked.

[0030] Refer to Figures 4-5 : The mounting base 101 is provided with a protection mechanism for buffering the collision with the inner wall of the mounting base 101 when the support frame 102 moves in the reverse direction of the material conveying for reset.

[0031] The protection mechanism includes a damping spring arranged between the mounting base 101 and the support frame 102 away from the end of the mounting base 101. By setting a pre-tightening force between the mounting base 101 and the support frame 102, the friction force of the sliding between the mounting base 101 and the support frame 102 is increased, the stability of the movement of the support frame 102 during reset is improved, the reset speed of the support frame 102 is slowed down, so as to reduce the collision force of the support frame 102 on the mounting base 101, and the service life of the equipment is improved.

[0032] Refer to Figures 4-6 : The light source is installed on the mounting plate 108, and the support frame 102 is provided with a plurality of positioning holes for adjusting the installation height of the mounting plate 108.

[0033] The installation height of the light source can be adjusted by installing the mounting plate 108 of the light source in the positioning holes at different heights, which is convenient for adapting to products of different sizes. When the brightness required for the detected product is not high, the installation height of the light source can be adjusted upwards. When the detected product requires a higher brightness, the installation height of the light source can be reduced. And this installation process is disassembled and assembled by bolts, with simple operation, which is convenient for the staff to adjust the height.

[0034] Refer to Figures 4-5 : The mounting plate 108 is provided with a rotating shaft, and the light source is hinged with the rotating shaft.

[0035] The side of the mounting plate 108 is hinged with the light source, and the irradiation angle can be adjusted by rotating the light source. When detecting different types of products, the sizes of the products are different, and the required light source irradiation angles are also different. When the irradiation angle needs to be adjusted, only the light source needs to be rotated, which is convenient for the operator to perform the adjustment work. Such adjustment operation is simple and improves work efficiency.

[0036] Refer to Figures 1-5 : A convex block protruding towards the baffle 103 is provided at the end edge of the dial 104, and the center of the convex block is in contact with the baffle 103.

[0037] The dial 104 is provided with a convex block in contact with the baffle 103. When the dial 104 retracts, since the protruding part of the dial 103 contacts the baffle 103, it is convenient for the dial 103 not to be interfered by the baffle 103 during retraction, and unnecessary damage to the baffle 103 or the dial 104 is avoided.

[0038] The above embodiments only represent one or several implementation manners of the present utility model, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the appended claims.
