[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] The utility model provides Figures 1 to 5 The LED bottom shell detection device shown includes:

[0027] A conveying assembly 1 for conveying LED bottom shells, the conveying assembly 1 includes a fixing frame 101 and two sets of conveyor belts 102;

[0028] A fixed box 2 is fixed to the top of the fixed frame 101. Two sets of first clamping plates 3 are movably provided on both sides of the inner cavity of the fixed box 2. A clamping assembly 4 for moving the first clamping plates 3 toward each other is provided in the inner cavity of the fixed box 2. The front and rear ends of the top of the fixed box 2 are rotatably connected to a rotating shaft 5 through a support frame. A second clamping plate 6 is fixed to the outside of the rotating shaft 5. The second clamping plate 6 is located in front and rear of the fixed box 2. A driving assembly 7 for deflecting the rotating shaft 5 is provided on the top of the fixed box 2.

[0029] The device further comprises a support plate 8 movably arranged in the inner cavity of the fixing frame 101. Positioning pins 9 for detecting the position of the mounting column on the LED bottom shell are fixed around the top of the support plate 8. An electric push rod 10 is fixed to the bottom of the fixing frame 101. The piston rod of the electric push rod 10 passes through the inner cavity of the fixing frame 101 and is fixedly connected to the bottom of the support plate 8.

[0030] The conveyor belt 102 driven by the support roller 103 continuously conveys the LED bottom shell. When the LED bottom shell is conveyed to the bottom of the fixed box 2, the clamping component 4 drives the two groups of first clamps 3 to clamp the LED bottom shell, and then the second clamp 6 clamps it again under the rotation of the rotating shaft 5. The first clamp 3 and the second clamp 6 are used to position the contour of the LED bottom shell, and then the support plate 8 and the positioning pin 9 located below are used to quickly detect the position of the installation column at the bottom of the LED bottom shell to avoid deviation in the position of the installation column, which causes the LED bottom shell to be unable to match with other accessories, while improving the efficiency of the device in continuously and uninterruptedly detecting the LED bottom shell.

[0031] The conveying assembly 1 also includes two groups of support rollers 103 that rotate in the inner cavity of the fixed frame 101 through bearings, and two groups of conveyor belts 102 are transmission-connected to the outside of the support rollers 103. A servo motor 104 is fixed to the outside of the fixed frame 101. The output shaft of the servo motor 104 is fixedly connected to the end of a group of support rollers 103. The servo motor 104 drives one group of support rollers 103 to rotate, and then the conveyor belt 102 rotates with the cooperation of the other group of support rollers 103, so as to facilitate the uninterrupted passage of the LED bottom shell from the bottom of the fixed box 2, thereby facilitating rapid detection.

[0032] The clamping assembly 4 includes a bidirectional screw 41 which is rotatably connected to the inner cavity of the fixed box 2 through a bearing. Both ends of the bidirectional screw 41 are threadedly connected with a screw sleeve 42. The screw sleeve 42 is fixedly embedded in the first clamping plate 3. A first drive motor 43 is fixed to the outside of the fixed box 2. The output shaft of the first drive motor 43 is fixedly connected to one end of the bidirectional screw 41. The bottom of the first clamping plate 3 passes through the fixed box 2 and extends downward. The bidirectional screw 41 is driven to rotate by the first drive motor 43, and then the bidirectional screw 41 drives the first clamping plate 3 to move toward each other through the screw sleeve 42, which is convenient for clamping and placing the LED bottom shell.

[0033] The driving assembly 7 includes a worm 71 which is rotatably connected to the top of the fixed box 2 through a support frame, a worm wheel 72 which meshes with the worm 71 is fixed to the outside of the rotating shaft 5, a second driving motor 73 is fixed to the top of the fixed box 2, and a driving gear 74 is fixed to the output shaft of the second driving motor 73. A driven gear 75 which meshes with the driving gear 74 is fixed at the center of the worm 71. The driving gear 74 is driven to rotate by the second driving motor 73, and the worm 71 is driven to rotate with the cooperation of the driven gear 75. At the same time, the worm 71 drives the two sets of rotating shafts 5 at both ends to rotate synchronously through the worm wheel 72, and then the rotating shaft 5 is flipped and clamped from the front and back of the LED bottom shell, and the LED bottom shell can be accurately positioned in cooperation with the first clamping plate 3.

[0034] An avoidance groove 11 is provided on the side of the second clamping plate 6 away from the rotating shaft 5. The width of the avoidance groove 11 is greater than the width of the conveyor belt 102. The setting of the avoidance groove 11 can prevent the second clamping plate 6 from contacting the conveyor belt 102, causing the second clamping plate 6 and the conveyor belt to shake, thereby affecting the clamping and limiting of the LED bottom shell.

[0035] Limiting rods 12 are fixed around the bottom of the support plate 8. The end of the limiting rod 12 away from the support plate 8 passes through the fixed frame 101 and extends downward. Through the setting of the limiting rod 12, it is convenient to limit the support plate 8 to prevent the support plate 8 from shaking during the up and down movement, resulting in deviation in the position of the positioning pin 9, and then causing deviation in the detection of the position of the column installed on the LED bottom shell.

[0036] An elastic support member is also provided on the top of the support plate 8, and the elastic support member includes a fixed seat 13 and a movable seat 14. The movable seat 14 is sleeved on the top of the fixed seat 13, and the inner cavities of the fixed seat 13 and the movable seat 14 are connected with a support spring 15. The elastic support member is used to conveniently support the positioning pin 9 before it contacts the LED bottom shell, so that the LED bottom shell moves up between the first splint 3 and the second splint 6 and fits the bottom of the fixed box 2.

[0037] When in use, the servo motor 104 is started, and the servo motor 104 drives a group of support rollers 103 to rotate, and then the conveyor belt 102 rotates with the cooperation of another group of support rollers 103, and the LED bottom shell can be continuously conveyed to the bottom of the fixed box 2. After the LED bottom shell moves to the bottom of the fixed box 2, the first drive motor 43 drives the bidirectional screw 41 to rotate, and then the bidirectional screw 41 drives the two groups of first splints 3 to move toward the middle through the screw sleeve 42. Subsequently, the second drive drives the drive gear 74 to rotate, and the driven gear is used to rotate. The wheel 75 drives the worm 71, and then the two sets of rotating shafts 5 are deflected through the worm gear 72, so that the two sets of second clamping plates 6 clamp the LED bottom shell from the outside to the inside, which can not only fix the LED bottom shell, but also facilitate the positioning of the LED bottom shell. Then the electric push rod 10 drives the support plate 8 to move upward, and the elastic support member first supports the LED bottom shell so that the top of the LED bottom shell fits against the bottom of the fixed box 2. Then the positioning pin 9 on the top of the support plate 8 detects the position of the installation column at the bottom of the LED bottom shell.

[0038] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
