Description

Technical Field

[0001] The invention relates to a lamp tube testing device. Background Art

[0002] After the lamp is produced, it needs to be tested, including high-voltage breakdown test and lighting test. After the lamp is placed on the fixture, it is necessary to clamp the lamp pins with a live clamp, and then energize the clamp to perform various tests. Using the live clamp to perform power-on tests is very cumbersome and inefficient. Summary of the Invention

[0003] The object of the present invention is to provide a high-efficiency lamp tube testing device.

[0004] To achieve the above-mentioned object, the present invention adopts the following technical scheme: a lamp tube testing device, comprising several test stations, each test station is provided with several test seat groups, each test seat group comprises a front test seat and a rear test seat arranged opposite to each other in the front and rear directions, the front test seat and the rear test seat each comprise several test seat units arranged in sequence along the left and right directions, each test seat unit has a test slot that opens upward and opens to the front or rear side, a power spring is provided in each test slot, the two power springs of each test seat unit are arranged symmetrically on the left and right, the power springs are arranged in an arc shape, the left power spring of the test seat unit is bent to form an arc structure opening to the left, the right power spring of the test seat unit is bent to form an arc structure opening to the right, a gap is formed between the upper end of the left power spring of the test seat unit and the right slot wall of the corresponding test slot, and a gap is formed between the upper end of the right power spring of the test seat unit and the left slot wall of the corresponding test slot.

[0005] When the present invention is used, it is only necessary to place both ends of the lamp tube on the test socket assembly so that the pins of the lamp tube are located in the test slots of the test socket unit and the circumferential outer walls of the pins are in contact with the power springs. Then, the power springs are energized to realize the test. There is no need to fix or remove the live clips for each pin, and the efficiency is high.

[0006] Preferably, each test socket unit has an upwardly extending guide protrusion in the middle, with the left end face of the guide protrusion contacting the left test slot wall, and the right end face of the guide protrusion contacting the right test slot wall. The guide protrusion serves to guide the lamp tube, facilitating the insertion of the lamp pin into the test slot.

[0007] Preferably, the width between the left and right side walls of at least the upper portion of the guide protrusion is gradually shortened from bottom to top. The above arrangement further facilitates the pins of the lamp tube to enter the test slot.

[0008] Preferably, the test station is equipped with at least two left-right clamping assemblies, each secured to the output end of a first linear motion mechanism. The first linear motion mechanism is secured to the output end of a second linear motion mechanism. The second linear motion mechanism is used to move the clamping assemblies left and right, while the first linear motion mechanism is used to move the clamping assemblies up and down. This arrangement enables simultaneous testing of multiple groups of lamps, thereby improving production efficiency.

[0009] Preferably, the front test seat and the rear test seat of the test seat group are both arranged on guide rails arranged along the front-to-back direction. The above arrangement enables the present invention to be used for testing lamps of different lengths.

[0010] Preferably, the front test seat and the rear test seat are both provided with threaded holes and equipped with fastening bolts, which are rotated to abut against the guide rail. The above arrangement facilitates the fixing of the front test seat and the rear test seat to the guide rail.

[0011] Preferably, a loading station is provided on the side of the test station, and a plurality of fixed seat groups are provided on the loading station, and the fixed seat group is composed of a pair of front-to-back symmetrical fixed seats, each fixed seat includes a plurality of fixed seat units arranged in sequence along the left-to-right direction, and the fixed seat unit includes an outer section and an inner section arranged along the front-to-back direction, the outer section has an upwardly opening adjustment groove, the inner section has an upwardly opening accommodating groove opening away from the outer section, the outer section has a left-right symmetrical structure, the width between the front groove wall and the rear groove wall of the adjustment groove gradually shortens from top to bottom, the width between the front groove wall and the rear groove wall of the adjustment groove is smaller than the width between the front groove wall and the rear groove wall at the corresponding height of the accommodating groove, and the bottom of the accommodating groove is located below the bottom of the adjustment groove.

[0012] 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 inner section receiving groove of the fixing seat unit, and the receiving groove is used to limit the left and right directions of the lamp tube so that the lamp tube will not move left or right. As the lamp tube is lowered, the pins on the side of the end of the lamp tube will contact the wall of the adjustment groove. Under the action of gravity and the limitation of the receiving groove, the lamp tube will rotate so that the pins all fall on the bottom of the adjustment groove, so that the heights of the lamp pins are the same, so that the pins of the lamp tube can enter the test groove in subsequent tests.

[0013] Preferably, the width between the front wall and the rear wall of the receiving groove gradually decreases from top to bottom. The above arrangement makes the receiving groove open, making it easier to place the lamp tube downward in the receiving groove.

[0014] Preferably, the bottom of the receiving groove is in an arc shape. The above arrangement further limits the rotation of the lamp tube.

[0015] Preferably, a defective product collection area is provided on the test seat group side of each test station, and the defective product collection area is composed of a plurality of fixed blocks with upward slots.

[0016] The present invention has the advantages of improving production efficiency and reducing labor intensity of workers. BRIEF DESCRIPTION OF THE DRAWINGS
