[0027] In the initial state, the first driving mechanism pulls the first test head 22 away from the first positioning fixture 21, and the second driving mechanism pulls the second test head 32 away from the second positioning fixture 31. The distance between the first positioning fixture 21 and the second positioning fixture 31 is set according to the length of the lamp tube 4; the manipulator transfers the lamp tube 4 to be fixed and the aging test (the two ends of the lamp tube body 41 are both pasted with the lamp head 42 in the uncured state with glue) to the present invention, so that the two ends of the lamp tube 4 are respectively placed on the first positioning fixture 21 and the second positioning fixture 31, and then the first driving mechanism releases the pulling force on the first test head 22 (the first driving mechanism does not apply pulling force to the first test head 22), so that the test end of the first test head 22 moves close to the first positioning fixture 21, and the second driving mechanism releases the pulling force on the second test head 32 (the second driving mechanism does not apply pulling force to the second test head 32), so that the second test The test end of the head 32 moves close to the second positioning fixture 31 until the test end of the first test head 22 abuts against the lamp head 42 at one end of the lamp tube 4 and is electrically connected to the lamp head 42, and the test end of the second test head 32 abuts against the lamp head 42 at the other end of the lamp tube 4 and is electrically connected to the lamp head 42, so that a circuit loop is formed among the power supply, the first test head 22, the lamp tube 4 and the second test head 32, and the power supply provides current to the lamp tube 4, thereby realizing an aging test on the lamp tube 4; during this process, the first test head 22 and the second test head 32 respectively abut against the lamp heads 42 at both ends of the lamp tube 4 to clamp and fix the lamp tube 4 in the present invention until the glue between the lamp head 42 and the lamp tube body 41 is cured, which not only ensures the position accuracy of the lamp head 42 installed on the lamp tube body 41 and the stability of the lamp tube 4 during the aging test, but also ensures that the lamp head 42 can be firmly adhered to the lamp tube body 41, thereby improving the quality of the lamp tube 4. The present invention has a simple structure and is easy to operate. It can not only fix the lamp tube 4, but also perform an aging test on the lamp tube 4, thereby ensuring the structural stability and quality of the lamp tube 4 and improving the efficiency of manufacturing the lamp tube 4. The present invention is particularly suitable for application in automated production equipment.

[0028] In order to meet the needs of fixing and aging tests for lamp tubes 4 of different length specifications, in this embodiment, the base 1 is provided with a slide rail 11, and the bottom of the second positioning fixture 31 is equipped with a first slider 23 that slides with the slide rail 11, and the first slider 23 is equipped with a first locking block 24 for locking the first slider 23 to the slide rail 11; in actual application, the distance between the second positioning fixture 31 and the first positioning fixture 21 is adjusted by adjusting the second positioning fixture 31 to move closer to or away from the first positioning fixture 21; during specific adjustment, the first slider 23 of the second positioning fixture 31 moves along the slide rail 11 to ensure the stability of the movement of the second positioning fixture 31, and when the position of the second positioning fixture 31 is adjusted to the set position, the first locking block 24 locks the first slider 23 on the slide rail 11, so that the second positioning fixture 31 is fixed on the slide rail 11, ensuring that the distance between the second positioning fixture 31 and the first positioning fixture 21 remains unchanged, so as to facilitate the fixation and aging tests of lamp tubes 4 of corresponding lengths. This structural design makes it easy to adjust the position of the second positioning fixture 31, with good adjustment stability, and can meet the needs of fixing and aging tests of lamp tubes 4 of different length specifications. It has strong practicality, good versatility and a wide range of applications.

[0029] In order to avoid the limitation of adjusting the distance between the first positioning jig 21 and the second positioning jig 31 and make the adjustment more convenient, in this embodiment, the bottom of the first positioning jig 21 is equipped with a second slider 33 that slides with the slide rail 11, and the second slider 33 is equipped with a second locking block 34 for locking the second slider 33 to the slide rail 11. In actual application, the first positioning jig 21 can also move closer to or away from the second positioning jig 31 along the slide rail 11 according to actual needs to adjust the distance between the first positioning jig 21 and the second positioning jig 31, and finally lock the second slider 33 to the slide rail 11 through the second locking block 34, so that the first positioning jig 21 is fixed to the slide rail 11. This structural design has good flexibility and is more convenient to adjust.

[0030] Of course, in order to improve the efficiency of adjustment and reduce the process of disassembly and assembly, the first positioning fixture 21 is generally fixed and only the position of the second positioning fixture 31 relative to the first positioning fixture 21 needs to be adjusted.

[0031] In this embodiment, the first test head 22 includes a first test seat 221 slidably disposed on one side of the first positioning fixture 21, a plurality of first test needle groups 222 installed on the first test seat 221, a first positioning plate 223 installed on the first test seat 221, and a test driving component 224 for driving the first test seat 221 to approach or move away from the first positioning fixture 21, one end of the first positioning plate 223 is used to abut against a side of the first positioning fixture 21 away from the second positioning fixture 31, and the other end of the first positioning plate 223 is used to abut against one end of the lamp tube 4, the first positioning plate 223 is provided with a plurality of first test holes 2231, the number of the plurality of first test holes 2231 is equal to the number of the plurality of first test needle groups 222, the plurality of first test holes 2231 and the plurality of first test needle groups 222 are arranged one-to-one, and one end of each group of first test needle groups 222 protrudes into a first test hole 2231 and is used to be electrically connected to the lamp holder 42 at one end of the lamp tube 4.

[0032] In actual operation, the first driving mechanism pulls the test driving component 224, so that the test driving component 224 drives the first test seat 221 to move away from the first positioning fixture 21, and the moving first test seat 221 drives the first positioning plate 223 and the plurality of first test needle groups 222 to move away from the first positioning fixture 21. When the plurality of lamps 4 to be fixed and subjected to aging tests are placed on the first positioning fixture 21 and the second positioning fixture 31, the first driving mechanism releases the pulling force on the test driving component 224, and the test driving component 224 drives the first test seat 221 to move close to the first positioning fixture 21, and the moving The first test seat 221 drives the first positioning plate 223 and several first test needle groups 222 to move close to the first positioning fixture 21 until the lower end of the first positioning plate 223 contacts one side of the first positioning fixture 21, and the upper end of the first positioning plate 223 contacts the end face of the lamp holder 42 at one end of the lamp tube 4, so as to press and fix the lamp holder 42 on the lamp tube body 41, and the first test needle group 222 is electrically connected to the two pins 43 on the lamp holder 42 at one end of the lamp tube 4, and at the same time, the second test head 32 is electrically connected to the two pins 43 on the lamp holder 42 at the other end of the lamp tube 4, so as to fix and perform aging tests on the lamp tube 4. When the number of the first test needle groups 222 is multiple, the present invention can fix and perform aging tests on multiple lamp tubes 4 at one time, which greatly improves the production efficiency and is particularly suitable for application in mass production.

[0033] Specifically, the first positioning plate 223 is also provided with a plurality of first deviation correction holes 2232, which are connected to a plurality of first test holes 2231 in a one-to-one correspondence. The first deviation correction holes 2232 are recessed from the side of the first positioning plate 223 close to the first positioning fixture 21, and the aperture of the first deviation correction hole 2232 gradually decreases from the outside to the inside (i.e., it is roughly a conical hole). The inner aperture of the first deviation correction hole 2232 is equal to the aperture of the first test hole 2231, and the first test hole 2231 is recessed from the side of the first positioning plate 223 away from the first positioning fixture 21. The first test needle group 222 includes two first test needles 229 arranged in parallel and at a distance, and the two first test needles 229 are respectively used to electrically connect with the two pins 43 of the lamp holder 42 at one end of the lamp tube 4. When the first positioning plate 223 contacts the lamp holder 42 at one end of the lamp tube 4, the first correction hole 2232 can correct the lamp tube 4 and the lamp holder 42, ensuring that the two pins 43 on the lamp holder 42 can be accurately and stably electrically connected to the two first test pins 229, ensuring that the aging test can be carried out normally, and improving the efficiency and quality of the aging test.

[0034] In this embodiment, the first test seat 221 is equipped with a first transition conductive rod 25, and the other end of each group of first test needle groups 222 protrudes out of the side of the first test seat 221 away from the first positioning plate 223 and is electrically connected to the first transition conductive rod 25 via a wire. The first positioning fixture 21 is equipped with a first fixed conductive rod 26 for electrically connecting to the first transition conductive rod 25, and the first fixed conductive rod 26 is electrically connected to the positive pole of the power supply via a wire. In the process of fixing and aging test of the lamp tube 4, in order to avoid the first test needle 229 being directly electrically connected to the positive pole of the power supply via a wire, to avoid the first test head 22 frequently moving back and forth, which may cause the wire welded on the first test needle 229 to break, detach, or the wire welded on the adjacent first test needle 229 to become knotted during the movement, and to prevent interference with the normal operation of fixing and aging test of the lamp tube 4, the present invention integrates and welds the current input ends of all the first test needles 229 to the current output end of the first transition conductive rod 25 via a wire, and then adds a first fixed conductive rod 26, and the first test seat 221 is close to or away from the first positioning fixture. During the movement of 21, the conduction and disconnection of the current are controlled by the interference or separation between the first transition conductive rod 25 and the first fixed conductive rod 26, and since the current input ends of all the first test needles 229 are integrated and welded to the current output ends of the first transition conductive rod 25 via wires, the first transition conductive rod 25 and all the first test needles 229 move synchronously with the first test socket 221, and the first fixed conductive rod 26 is fixed on the first positioning fixture 21 and does not move. Therefore, when the present invention is working, there will be no problems such as wire breakage, wire detachment without power supply, and knotting between adjacent wires, thereby reducing the probability of failure of the present invention and extending the service life of the present invention.

[0035] In this embodiment, the test drive assembly 224 includes a first guide rod 225, a first elastic member 226, a first pull plate 227 and a limit plate 228. The first test seat 221 is located between the first positioning plate 223 and the first pull plate 227. The first test seat 221 is provided with a first guide hole. The first positioning fixture 21 is provided with a second guide hole connected to the first guide hole. The first guide rod 225 passes through the first guide hole and the second guide hole. The first pull plate 227 is installed at one end of the first guide rod 225 protruding from the first guide hole. The first pull plate 227 is connected to the first test seat 221. The limit plate 228 is installed at one end of the first guide rod 225 protruding from the second guide hole. One end of the first elastic member 226 abuts against the first positioning fixture 21, and the other end of the first elastic member 226 abuts against the limit plate 228.

[0036] When the first driving mechanism pulls the first pull plate 227 of the test driving assembly 224 to move away from the first positioning fixture 21, the first pull plate 227 drives the first guide rod 225, the first test seat 221, the first positioning plate 223 and other structures to move away from the first positioning fixture 21. During this process, the limit plate 228 squeezes the first elastic member 226, causing the first elastic member 226 to undergo elastic deformation; when the first driving mechanism releases the pulling force on the first pull plate 227 of the test driving assembly 224, the first elastic member 226 returns to its original state. Under the action of the rebound force of the first elastic member 226, the first elastic member 226 drives the first pull plate 227 to reset and push the first guide rod 225, the first test seat 221, the first positioning plate 223 and other structures to move synchronously close to the first positioning fixture 21 until the first positioning plate 223 contacts the lamp holder 42 at one end of the lamp tube 4, and the first test pin 229 is electrically connected to the pin 43 of the lamp holder 42. This structural design not only allows the first positioning plate 223 and the first test socket 221 to reset automatically, but also always provides thrust to the first positioning plate 223 when the first positioning plate 223 contacts the lamp holder 42, so that the first positioning plate 223 can stably press the lamp holder 42 onto the lamp tube body 41.

[0037] Specifically, the first elastic member 226 is a compression spring or a return spring, which has a simple structure, low cost, easy assembly and replacement, and a long service life. The first elastic member 226 is sleeved on the outside of the first guide rod 225, and the first guide rod 225 guides and limits the first elastic member 226 to prevent the first elastic member 226 from tilting or bending when being squeezed, thereby ensuring that the first elastic member 226 can work normally; the first pull plate 227 is fixedly connected to the first test seat 221 via the connecting rod 27, and the outer side of the first guide rod 225 is sleeved with a spacer sleeve 28, and the inner wall of the spacer sleeve 28 is slidably connected to the outer wall of the first guide rod 225, and the connecting rod 27 and the spacer sleeve 28 are both located between the first pull plate 227 and the first test seat 221, and the length of the spacer sleeve 28 is the same as the length of the connecting rod 27 By adding a connecting rod 27, it is convenient for the first pull plate 227 to drive the first test seat 221 to move back and forth. By adding a spacer 28, there is a space between the first test seat 221 and the first pull plate 227 for the first driving mechanism to pull the first pull plate 227, which is convenient for the first driving mechanism to pull the first pull plate 227 to move. The number of the first guide holes, the number of the second guide holes, the number of the limit plates 228, the number of the first guide rods 225 and the number of the first elastic members 226 are all two. The two first guide rods 225 are respectively located on both sides of the connecting rod 27, and one first elastic member 226 is sleeved outside one first guide rod 225. This structural design makes the first test seat 221 and the first positioning plate 223 evenly stressed, and improves the stability of the movement of the first test seat 221 and the first positioning plate 223. Of course, the spacer 28 can also be replaced by a guide sleeve or a linear bearing, so that the movement of the first test seat 221 and the first positioning plate 223 is smoother and more stable.

[0038] In this embodiment, the first positioning fixture 21 is provided with a plurality of first positioning grooves 211, and the second positioning fixture 31 is provided with a plurality of second positioning grooves 311. The number of the first positioning grooves 211 is equal to the number of the second positioning grooves 311, and the plurality of first positioning grooves 211 and the plurality of second positioning grooves 311 are arranged one-to-one, the number of the first test needle groups 222 is equal to the number of the first positioning grooves 211, and the plurality of first test needle groups 222 and the plurality of first positioning grooves 211 are arranged one-to-one, and the first positioning groove 211 and the second positioning groove 311 are both semicircular. The two ends of the lamp tube 4 are respectively accommodated in the first positioning groove 211 and the second positioning groove 311, and the inner wall of the first positioning groove 211 and the inner wall of the second positioning groove 311 contact the outer side of the lamp tube 4 to position the lamp tube 4, so as to avoid the lamp tube 4 from being offset during the aging test, and ensure the stability of the lamp tube 4. When the number of the first positioning grooves 211 and the number of the second positioning grooves 311 are both plural, and the number of the first test needle groups 222 is plural, the present invention can perform fixation and aging tests on multiple lamp tubes 4 at one time, thereby improving production efficiency.

[0039] In this embodiment, the second test head 32 includes a second test seat 321 connected to the second positioning fixture 31 and a plurality of aging test components 322 slidably set on the second test seat 321, the second test seat 321 is L-shaped, the number of aging test components 322 is equal to the number of second positioning grooves 311, the plurality of aging test components 322 are arranged in a one-to-one correspondence with the plurality of second positioning grooves 311, and the second driving mechanism is used to pull the plurality of aging test components 322 to move synchronously away from the second positioning fixture 31. Since errors may occur in the process of producing the lamp tubes 4, even lamp tubes 4 with the same length specifications may have inconsistent lengths, and it is impossible to ensure that the length of each lamp tube 4 is completely consistent. In order to ensure that the lamp tubes 4 with processing errors in length can be accurately and correctly fixed and aged, the present invention uses an aging test component 322 to contact and electrically connect with the lamp head 42 of the lamp tube 4 in a second positioning groove 311. Each aging test component 322 works independently without affecting each other. Each aging test component 322 can adjust itself according to the length of the lamp tube 4 at the corresponding position. Even if the lengths of multiple lamp tubes 4 are inconsistent due to processing errors, there will be no phenomenon that individual lamp tubes 4 cannot be fixed and aged. It is ensured that all lamp tubes 4 on the first positioning fixture 21 and the second positioning fixture 31 can be fixed and aged at the same time, and the practicability is strong.

[0040] In this embodiment, the aging test assembly 322 includes a second positioning plate 323, a second guide rod 324, a second pull plate 325, a second elastic member 326 and a second test needle group 327 installed on the second positioning plate 323, the second positioning plate 323 is located at the end of the second positioning groove 311 away from the first positioning fixture 21, the second guide rod 324 is slidably connected to the second test seat 321, the second positioning plate 323 is installed at one end of the second guide rod 324 protruding from the second test seat 321, the second pull plate 325 is installed at the other end of the second guide rod 324 protruding from the second test seat 321, the second elastic member 326 is located between the second positioning plate 323 and Between the second test socket 321, one end of the second elastic member 326 abuts against the second positioning plate 323, and the other end of the second elastic member 326 abuts against the second test socket 321. One end of the second positioning plate 323 is used to abut against the side of the second positioning fixture 31 away from the first positioning fixture 21, and the other end of the second positioning plate 323 is used to abut against the other end of the lamp tube 4. The second test needle group 327 is used to electrically connect with the lamp holder 42 at the other end of the lamp tube 4. The second test needle group 327 includes two second test needles 328 arranged in parallel and at a distance. The two second test needles 328 are respectively used to electrically connect with the two pins 43 of the lamp holder 42 at the other end of the lamp tube 4.

[0041] When the second driving mechanism pulls the second pull plate 325 of the aging test component 322 to move away from the second positioning fixture 31, the second pull plate 325 drives the second guide rod 324, the second positioning plate 323 and the second test needle group 327 to move away from the second positioning fixture 31. During this process, the second positioning plate 323 squeezes the second elastic member 326, causing the second elastic member 326 to undergo elastic deformation. When the second driving mechanism releases the pulling force on the second pull plate 325 of the aging test component 322, the second elastic member 326 returns to its original state. Under the action of the rebound force of the second elastic member 326, the second elastic member 326 drives the second pull plate 325 to reset and push the second guide rod 324, the second positioning plate 323 and the second test needle group 327 to move closer to the second positioning fixture 31 until the upper end of the second positioning plate 323 contacts the lamp holder 42 at the other end of the lamp tube 4, and the second test needle 328 is electrically connected to the pin 43 of the lamp holder 42. This structural design not only enables the second positioning plate 323, the second test needle group 327 and the second guide rod 324 to automatically reset, but also always provides thrust to the second positioning plate 323 when the second positioning plate 323 contacts the lamp holder 42, so that the second positioning plate 323 can stably press the lamp holder 42 onto the lamp tube body 41.

[0042] Specifically, there are two second guide rods 324 , and the two second guide rods 324 are arranged in parallel with each other at a distance, so as to further improve the stability of the movement of the second positioning plate 323 .

[0043] In this embodiment, the second positioning plate 323 is provided with a second test hole 35 and a second correction hole 36 connected to the second test hole 35 in sequence from the inside to the outside. The second correction hole 36 is recessed from the side of the second positioning plate 323 close to the second positioning fixture 31. The aperture of the second correction hole 36 gradually decreases from the outside to the inside (that is, it is roughly a conical hole). The inner aperture of the second correction hole 36 is equal to the aperture of the second test hole 35. The second test hole 35 is recessed from the bottom wall of the second correction hole 36. One end of the second test needle group 327 protrudes into the second test hole 35 and is used to be electrically connected to the lamp holder 42 at the other end of the lamp tube 4. The other end of the second test needle group 327 protrudes out of the second test socket 321. When the second positioning plate 323 contacts the lamp holder 42 at the other end of the lamp tube 4, the second correction hole 36 can correct the lamp tube 4 and the lamp holder 42, ensuring that the two pins 43 on the lamp holder 42 can be accurately and stably electrically connected to the two second test pins 328, ensuring that the aging test can be carried out normally, and improving the efficiency and quality of the aging test.

[0044] Specifically, the second elastic member 326 is a compression spring or a return spring, which has a simple structure, low cost, easy assembly and replacement, and a long service life. The second elastic member 326 is sleeved on the outside of the second guide rod 324, and the second guide rod 324 guides and limits the second elastic member 326 to prevent the second elastic member 326 from tilting or bending when being squeezed, thereby ensuring that the second elastic member 326 can work normally; the outer side of the second guide rod 324 is sleeved with an extended linear bearing 37, and the extended linear bearing 37 is located on the second test seat 321 Between the second pull plate 325, one end of the extended linear bearing 37 is fixedly connected to the second test seat 321; by adding the extended linear bearing 37, on the one hand, it guides the movement of the second guide rod 324, improves the stability of the movement of the second guide rod 324, and then improves the stability of the movement of the second positioning plate 323 and the second test needle group 327; on the other hand, it allows a space for the second driving mechanism to pull the second pull plate 325 between the second test seat 321 and the second pull plate 325, which facilitates the second driving mechanism to pull the second pull plate 325 to move.

[0045] In this embodiment, the second positioning plate 323 is provided with a second transition conductive rod 38 electrically connected to one end of the second test needle group 327 protruding out of the second test socket 321, the second test needle group 327 is electrically connected to the second transition conductive rod 38 via a wire, and the second positioning fixture 31 or the second test socket 321 is provided with a second fixed conductive rod 39 for electrically connecting to the second transition conductive rod 38. In the process of fixing and aging test of the lamp tube 4, in order to avoid the second test needle 328 being directly electrically connected to the negative pole of the power supply via a wire, to avoid the second test head 32 from frequently moving back and forth, which may cause the wire welded on the second test needle 328 to break, detach, or the wire welded on the adjacent second test needle 328 to become knotted during the movement, so as to prevent interference with the normal operation of fixing and aging test of the lamp tube 4, the present invention integrates and welds the current input ends of the two second test needles 328 of each group of second test needle groups 327 to the current output end of the second transition conductive rod 38 via a wire, and then adds a second fixed conductive rod 39. In the process of the second positioning plate 323 moving close to or away from the second positioning fixture 31, the second fixed conductive rod 39 is provided. The second transition conductive rod 38 and the second fixed conductive rod 39 are contacted or separated to control the conduction and disconnection of the current, and since the current input ends of the two second test pins 328 of each group of second test pin groups 327 are integrated and welded to the current output end of the second transition conductive rod 38 through wires, the second transition conductive rod 38 and the two second test pins 328 of each group of second test pin groups 327 move synchronously with the second positioning plate 323, and the second fixed conductive rod 39 is fixed on the second positioning fixture 31 or the second test seat 321 and does not move. Therefore, when the present invention is working, there will be no problems such as wire breakage, wire detachment and no power supply, and knotting between adjacent wires, thereby reducing the probability of failure of the present invention and extending the service life of the present invention.

[0046] Specifically, both ends of the base 1 are provided with wire holes for passing the wires, which shortens the wire length required for electrically connecting the positive pole of the power supply with the first fixed conductive rod 26 and the negative pole of the power supply with the second fixed conductive rod 39, facilitates the routing of the wires in the present invention, and limits the wires by the wire holes to prevent the wires from swinging.

[0047] Specifically, the first transition conductive rod 25 and the second transition conductive rod 38 are both copper screws. Copper screws have good conductivity, low resistivity, and low power loss, which achieves the purpose of energy saving and environmental protection. The first transition conductive rod 25 is threadedly connected to the first test socket 221, and the second transition conductive rod 38 is threadedly connected to the second positioning fixture 31 or the second test socket 321, making the disassembly and maintenance of the first transition conductive rod 25 and the second transition conductive rod 38 convenient and quick.

[0048] All technical features in this embodiment can be freely combined according to actual needs.

[0049] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention may also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
