Description

Technical Field

[0001] The present invention relates to the technical field of LED lamp tube processing, and particularly relates to an efficient automatic disassembly device for LED lamp tubes. Background Art

[0002] LED lamp tubes are also commonly known as fluorescent tubes and daylight tubes. Their light sources use LEDs as light emitters. An LED lamp tube includes two lamp sockets, a lamp tube, a lamp strip, and a driving power supply. The lamp strip is installed inside the lamp tube through a fixing glue. The two lamp sockets are plugged and fixed at both ends of the lamp tube through the fixing glue. The two lamp sockets are connected to the lamp strip and the driving motor through connecting wires.

[0003] After the existing LED lamp tubes are manufactured, they need to be powered on for detection to determine whether the products are working properly. However, during the detection process, there are often some unqualified products, and the unqualified rate is between 0.2% and 0.5%. After research, it is found that there are mainly three reasons why the LED lamp tubes cannot work properly. One is that the lamp strip is damaged, another is that the driving power supply is damaged, and the last one is that both are damaged (the probability is extremely small). During the entire manufacturing cost process of the LED lamp tube, the procurement costs of the lamp strip, the lamp tube, and the driving power supply account for a relatively large proportion. To save costs and recycle resources, manual disassembly of the LDE lamp tube is adopted, that is, the LED lamp tube is heated to emulsify the fixing glue, then the lamp socket is removed and the lamp strip and the driving motor are pulled out. At the same time, after cutting the connecting wires between them, the components are placed separately and classified. Then, the classified lamp strip and the driving power supply are electrically detected to determine whether they can work properly. The qualified components are selected and finally the connecting wires are removed. During the entire process, the manual disassembly of the LDE lamp tube takes the most time and has the slowest efficiency. Therefore, there is an urgent need to design an automatic disassembly device to automatically disassemble the LDE lamp tube to improve work efficiency. Summary of the Invention

Embodiment

[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0040] Embodiment: Refer to Figures 1-7 A shown highly efficient automatic disassembling device for LED lamp tubes, comprising two lamp holder clamping units 7, a left tangent unit 8, a right tangent unit 9, two pushing units 6 for pushing the two lamp holder clamping units 7, the left tangent unit 8, and the right tangent unit 9 to move, a power unit for driving the two pushing units 6 to move, and a heating unit for heating the lamp tube;

[0041] The power unit includes a top plate 2 and a bottom plate 1 connected to a vertical column 3, a driving motor 12 installed on the top plate 2, and two L-shaped limiting plates 4 installed on the top of the top plate 2. A driving gear 13 is fixed on the output shaft of the driving motor 12, and the driving gear 13 is respectively engaged with two toothed plates 5. The outer ends of the two toothed plates 5 are slidably arranged in the limiting grooves of the corresponding L-shaped limiting plates 4; the pushing unit 6 includes a push rod 61 whose upper end passes through a movable opening provided on the top plate 2 and a fixing plate 62 fixed to the upper end of the push rod 61. The lower end of the fixing plate 62 is in sliding contact with the upper end of the top plate 2. The push rod 61 is slidably connected to the bottom plate 1 through a first T-shaped block 63 provided at its bottom, and a second T-shaped block 64 is fixed to the lower end of the push rod 61; the fixing plate 62 of the left pushing unit 6 is fixedly connected to the left toothed plate 5, and there is a movable gap between the fixing plate 62 of the right pushing unit 6 and the end of the right toothed plate 5. The push rod 61 of the right pushing unit 6 is connected to the two right vertical columns 3 through a return spring 22; the lamp holder clamping unit 7 includes two cross bars 71 whose upper ends are both fixed with clamping blocks 72, and a slide rail 74 adapted to the second T-shaped block 64 is fixed on the two cross bars 71. The lower ends of the two slide rails 74 are both fixed with limiting rods 73, and the lower ends of the limiting rods 73 are located in a moving groove 17 provided on the bottom plate 1. The moving groove 17 includes a straight groove and inclined grooves respectively connected to both ends of the straight groove. Both inclined grooves are arranged to open outwards in a shape of an eight-character; the left cutting unit 8 includes four left mounting seats 81 slidably arranged on the bottom plate 1 through sliders 83 and arranged in pairs opposite to each other and equipped with left cutting knives 84, and two first L-shaped movable plates 85 and two second L-shaped movable plates 86 which are arranged in pairs opposite to each other and are provided with L-shaped movable cavities on them. The first L-shaped movable plates 85 and the second L-shaped movable plates 86 on the same side are connected by a column body. The left ends of the two first L-shaped movable plates 85 are both fixedly connected to the push rod 61. First limiting columns 82 penetrating the L-shaped movable cavities are provided on all four left mounting seats 81; the right cutting unit 9 includes two right mounting seats 92 arranged opposite to each other and longitudinally slidably arranged on the bottom plate 1 and two third L-shaped movable plates 91 arranged opposite to each other and one end of which is fixedly connected to the push rod 61. Right cutting knives 93 are installed on both right mounting seats 92. L-shaped movable cavities are arranged on both third L-shaped movable plates 91. Second limiting columns 94 penetrating the L-shaped sliding cavities are provided on both right mounting seats 92; the L-shaped movable cavities of the first L-shaped movable plates 85, the second L-shaped movable plates 86 and the third L-shaped movable plates 91 include a straight cavity and an inclined cavity opening outwards; the heating unit includes a lower heater 10 with a heating cavity and fixedly arranged on the bottom plate 1 and an upper heater 11 rotatably arranged with the lower heater 10; blanking openings 15 are respectively arranged on the left and right of the bottom plate 1; a control unit 14 for automatically controlling the covering and opening of the upper heater 11 and the lower heater 10 is also included.

[0042] During use (before use, the upper heater 11 and the lower heater 10 have been preheated and can heat the long lamp tube placed in the heating cavity), in the initial state, the upper heater 11 and the lower heater 10 are in an open state. Place the long lamp tube in the heating cavity of the lower heater 10, and make the lamp sockets at both ends of the long lamp tube partially located outside the heating cavity (the exposed part of the lamp socket should not be too large, otherwise the internal fixing glue cannot be completely melted. Generally, the exposed part is 1 cm to 1.(5 cm is fine). When placing, one end of the long lamp tube with the driving power supply should be set as the left end. After placing, there is a push switch on the bottom plate 1, which controls the operation of the driving motor 12. Driven by the rotating driving gear 13, the two toothed plates 5 move away from each other. The left toothed plate 5 will push the left push rod 61 to move outwards. The push rod 61 drives the lamp holder clamping unit 7 to move. The two cross bars 71 move along the track of the moving groove 17 through the limiting rod 73, so that the two clamping blocks 72 on the two cross bars 71 move closer to clamp the lamp holder at the left end of the long lamp tube. Then, the two clamping blocks 72 in the clamping state move to the left. When the left lamp holder detaches from the long lamp tube, the right toothed plate 5 contacts the right push rod 61, and the right push rod 61 drives the two clamping blocks 72 on the right to move closer for clamping, and can tear off the right lamp holder from the long lamp tube and move it in a straight line to the right. When the driving power supply moves into the space enclosed by the four left cutting knives 84 on the left, and the left lamp holder moves outside the two leftmost left cutting knives 84 on the left, and the right lamp holder is located on the right side of the two right cutting knives 93, at this time, the four first limiting columns 82 and the two second limiting columns 94 both move from the straight cavity to the inclined cavity. As the two push rods 61 continue to move, the first limiting columns 84 and the second limiting columns 94 in the moving inclined cavity are squeezed and will drive the four left cutting knives 84 and the two right cutting knives 93 to move closer for cutting, and can cut off the connecting wires between the left lamp holder and the driving power supply, the connecting wires between the driving power supply and the lamp strip, and the connecting wires between the right lamp holder and the lamp strip. After the connecting wires are cut off, the driving power supply directly drops through the blanking opening 15 (a receiving bucket can be placed below it in advance). The push rod 61 drives the cross bar 71 to continue moving away from the long lamp tube. At this time, the limiting rod 73 moves into the inclined groove, so that the two clamping blocks 72 move apart, and the clamping state of the lamp holder can be released. At this time, the lamp holder can drop downward through the blanking opening 15 (a receiving bucket can be placed at this dropping place). After completion, the driving motor 12 rotates in the reverse direction to drive all components to return to their original positions. Among them, the right push rod 61 can return to its original position with the assistance of the return spring 22. At this time, take out the long lamp tube in the heating cavity and take out the lamp strip inside. The fixing glue of the lamp strip has been heated and melted in the heating cavity, and the lamp strip can be directly taken out of the long lamp tube. There is also a control unit 14. Before the clamping block 72 clamps the lamp holder, the control unit 14 can control the upper heater 11 and the lower heater 10 to close and heat the entire lamp tube. When the clamping block 72 clamps the lamp holder, the fixing glue between the lamp holder and the long lamp tube has melted. After cutting the connecting wires and all components return to their original positions, the control unit 14 controls the upper heater 11 to rotate, and the operator can remove the long lamp tube from the lower heater 10.

[0043] It should be noted that: First, before the lamp holder is clamped and moved by the clamping block 72, the fixing glue between the lamp holder and the outer wall of the long lamp tube has been melted (through direct heating and heat conduction) to facilitate the separation of the lamp holder from the clamping block 72. Second, when cutting the connecting wires, the connecting wires at each part are in a straightened state. At this time, the lamp strip is inside the long lamp tube, the driving power supply is in the space surrounded by the four left cutting knives 84, and the two lamp holders are respectively located outside the left cutting knife 84 and the right left cutting knife 83. Third, the operator needs to wear labor protection gloves to remove the processed long lamp tube to avoid scalding. Fourth, the push switch can control the driving motor to drive the entire device to complete the disassembly process of a long lamp tube. Each time before disassembly, only the push switch needs to be pressed. The push switch is electrically connected to the PLC controller, and the operating state, speed, and interval time of the driving motor can be programmed and set. Fifth, when the upper heater 11 and the lower heater 10 are closed, the tube body of the long lamp tube is squeezed and fixed in the heating cavity, and the lamp holder is not squeezed to avoid affecting the disassembly and movement of the lamp holder by the clamping block 72. Sixth, this device is a high-level version, and a low-level version is applied for on the same day. The cost and working efficiency of the high-level version are higher than those of the low-level version.

[0044] As a preferred implementation manner in this embodiment, as Figures 7-10 shown, the control unit 14 includes a driving rod 144 rotatably arranged between the bottom plate 1 and the top plate 2 and having a spiral groove, a mounting block 147 slidably connected to the vertical rod 146, and two meshing transmission gears 148. The mounting block 147 is connected to the driving rod 144 through a movable tube 142 internally provided with a slide rod 143. The end of the slide rod 143 is slidably arranged in the spiral groove. The two transmission gears 148 are respectively mounted on the output shafts of the driving rod 144 and the driving motor 12. The mounting block 147 is movably connected to the upper heater 11 in an open state through a telescopic rod 149. A compression spring 1410 is installed in the telescopic rod 149. When the driving motor 12 works, the driving rod 144 can be driven to rotate through the two meshing transmission gears 148, so that the sliding tube 142 moves downward under the cooperation of the slide rod 143 and the spiral groove, which can drive the upper heater 11 to rotate and close with the lower heater 10 to perform closed heating on the long lamp tube in the heating cavity to prevent heat loss. When the movable tube 142 continues to move downward, the compression spring 1410 will be compressed. During this compression time, the clamping block 72 clamps and moves the lamp holder and performs cutting operations. When the driving motor 12 rotates in reverse, the movable tube 142 moves upward, which can drive the compression spring 1410 and the upper heater 11 to return to their original positions. At this time, the heater is in an open state, which is convenient for subsequent personnel to place the tube, eliminating the need for manual flipping of the upper heater 11 by personnel, reducing labor intensity, and improving work efficiency.

[0045] It should be noted that, first, to ensure that the LED lamp has sufficient heating time, the distance between the two clamping blocks 72 can be changed by extending the length of the initial bevel of the movable groove to provide sufficient time for the fixing glue to melt; second, after the cover is closed and heated for a period of time, the clamping blocks 72 will not contact the outer wall of the lamp holder to ensure that the fixing glue has melted.

[0046] In this embodiment, if Figure 8 As shown, the spiral groove includes a first spiral groove 141 and a second spiral groove 145 that are connected to each other. The distance between the two adjacent grooves on the first spiral groove 141 is greater than the distance between the two adjacent grooves on the second spiral groove 145. When the running speed of the movable tube 142 on the first spiral groove 141 is greater than the movement speed on the second spiral groove 145, the covering and opening movements of the heater 11 and the lower heater 10 are completed by the movable tube 142 on the first spiral groove 141. The rapid covering and opening movements improve work efficiency and also provide sufficient heating time for the closed heating of the LDE lamp tube. The compression and resetting of the extrusion spring 1410 are both completed by the movable tube 142 on the second spiral groove 145, which can reduce the compression amount of the extrusion spring 145 and prevent excessive force from acting on the upper heater 11 and causing damage to it.

[0047] As a preferred implementation in this embodiment, Figure 7 As shown, a plurality of first elastic heat-resistant pads 18 with C-shaped structures are provided in the heating chambers of the upper heater 11 and the lower heater 10. The first elastic heat-resistant pads 18 can buffer the squeezing effect between the long lamp tube body and the upper heater 11 and the lower heater 10, thereby preventing the long lamp tube body from being crushed.

[0048] It should be noted that the outer surface of the first elastic heat-resistant pad 18 can be set to a rough surface to enhance the friction between the tube body and prevent the tube body from moving.

[0049] As a preferred implementation in this embodiment, Figure 2 As shown, the inner cavity of the left side discharge opening 15 is provided with a discharge partition 16, and the lower end of the discharge partition 16 is located below the discharge opening 15. A receiving bucket can be placed on both sides of the discharge partition 16 to catch the falling lamp holder and driving power supply. The discharge partition 16 can prevent the lamp holder and driving power supply from being mixed in one receiving bucket, and no subsequent sorting operation is required.

[0050] As a preferred implementation in this embodiment, not shown in the figure, a second elastic heat-resistant pad is provided on the inner concave surface of the clamping block 72, which can buffer the pressure between the clamping block 72 and the lamp holder to prevent the long lamp tube from being crushed, and the inner concave surface of the second elastic heat-resistant pad is set to a rough surface, which can enhance the friction between the clamping block 72 and the lamp holder to prevent the lamp holder from slipping.

[0051] As a preferred implementation manner in this embodiment, as Figure 1 shown, two pads 19 are fixedly arranged on the left and right at the bottom of the bottom plate 1, and support plates 20 are rotatably arranged on both pads 19 through hinges. The width of the installation part 21 of the support plate 20 is greater than the thickness of the pad 19. The arrangement of the support plate 20 enables the device to have a certain height from the installation surface, providing space for placing the material receiving bucket. When the device is not installed, the support plate 20 can rotate inwards, and the pad 19 contacts the placement surface, reducing the occupied space.

[0052] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
