Description

Technical Field

[0001] The present invention relates to a lamp tube feeding mechanism. Background Art

[0002] After the lamp tube is produced, it needs to be detected. Existing detections are mostly carried out by automated detection equipment. It only needs to place the lamp tube on the lamp tube fixing seat at the feeding station, and then the automated detection equipment picks up the lamp tube through the clamping jaws. The automated detection equipment has a detection head for contacting the lamp tube pins. Place the lamp tube on the lamp tube fixing seat at the detection station so that the lamp tube pins contact the detection head, and then power on to detect whether there is a short circuit in the internal circuit of the lamp tube. To ensure the correct contact between the lamp tube pins and the detection head, workers need to rotate the lamp tube at the feeding station so that the two pins of the lamp tube are at the same height, which has low efficiency and increases the labor intensity of workers. Summary of the Invention

[0003] The object of the present invention is to provide a lamp tube feeding mechanism that can automatically adjust the lamp tube so that the lamp tube pins are all at the same height.

[0004] To achieve the above object, the present invention adopts the following technical scheme: A lamp tube feeding mechanism includes a fixing seat group for supporting the lamp tube. The fixing seat group is composed of a pair of symmetric front and rear fixing seats. Each fixing seat includes a plurality of fixing seat monomers arranged in sequence in the left-right direction. The fixing seat monomer includes an outer section and an inner section arranged in the front-rear direction. The outer section has an adjusting groove with an upward opening. The inner section has a receiving groove with an upward opening and an opening towards the side away from the outer section. The outer section has a left-right symmetric structure. The width between the front groove wall and the rear groove wall of the adjusting groove gradually shortens from top to bottom. The width between the front groove wall and the rear groove wall of the adjusting groove is smaller than the width between the front groove wall and the rear groove wall at the corresponding height of the receiving groove. The bottom of the receiving groove is located below the bottom of the adjusting groove.

[0005] When the present invention is used, when the lamp tube is placed in the fixing seat group from top to bottom, the end of the lamp tube is located in the receiving groove of the inner section of the fixing seat monomer, and the receiving groove is used to limit the lamp tube in the left-right direction so that the lamp tube will not move left or right. As the lamp tube is lowered, the pins on the side of the lamp tube end will contact the groove wall of the adjusting groove. Under the action of gravity and the limitation of the receiving groove, the lamp tube will rotate self-correctingly so that the pins all fall on the bottom of the adjusting groove. The present invention can realize the self-rotation adjustment of the lamp tube. Workers only need to place the lamp tube on the fixing seat group, and there is no need to rotate and adjust the lamp tube, which has higher efficiency and lower labor intensity for workers.

[0006] Preferably, the width between the front groove wall and the rear groove wall of the receiving groove gradually shortens from top to bottom. The above setting makes the receiving groove in an open shape, which is more convenient for the lamp tube to be placed downward into the receiving groove.

[0007] Preferably, the bottom of the receiving groove is arc-shaped. The above setting further restricts the rotation of the lamp tube.

[0008] Preferably, the fixing seat group is arranged on the working station. The working station includes a loading station, an inspection station and a unloading station arranged in sequence along the left-right direction. There are two fixing seat groups arranged along the left-right direction on the loading station. There are at least two jaw assemblies arranged along the left-right direction above the working station. The jaw assemblies are all fixed to the output end of the first linear moving mechanism. The first linear moving mechanism is fixed to the output end of the second linear moving mechanism. The second linear moving mechanism is used to move the jaw assemblies left and right. The first linear moving mechanism is used to move the jaw assemblies up and down. In the present invention, two groups of jaw assemblies are provided. When one group of jaw assemblies is used to move the lamp tube at the loading station to the inspection station, the other group of jaw assemblies is used to move the lamp tube at the inspection station to the unloading station. The above setting improves the production efficiency.

[0009] Preferably, there is a notch on the bottom plate. A third linear moving mechanism is arranged on the lower side of the bottom plate. The output end of the third linear moving mechanism is provided with a fourth linear moving mechanism. The output end of the fourth linear moving mechanism is provided with a lifting seat. There are several support grooves penetrating left and right on the lifting seat. The fourth linear moving mechanism is used for the lifting of the lifting seat. The third linear moving mechanism is used for the left and right movement of the lifting seat. After the worker finishes placing the lamp tube, the lamp tube is moved to the fixing seat group where the jaw assembly can pick it up through the third linear moving mechanism and the fourth linear moving mechanism. When the jaw performs loading on the lamp tube, since one fixing seat group is empty, the worker can manually load this fixing seat group to realize continuous loading of the lamp tube, so as to...

[0010] Preferably, the outer section penetrates the fixing seat monomer away from the inner section side, and the pin length of the lamp tube is greater than the axial length of the adjustment groove. The above setting makes the consumables of the fixing seat monomer less, and at the same time reduces the contact area between the pin and the groove wall of the outer section adjustment groove, so as to facilitate the self-rotation adjustment of the lamp tube.

[0011] The present invention has the advantages of improving production efficiency and reducing the labor intensity of workers. BRIEF DESCRIPTION OF THE DRAWINGS
