Description

Technical Field

[0001] This invention relates to the field of LED fluorescent tube processing, and more particularly to an automatic LED fluorescent tube gripping and loading device. Background Technology

[0002] LED fluorescent tubes, also known as LED daylight lamps or LED energy-saving lamps, are lighting devices that use light-emitting diodes (LEDs) as the light source. During the manufacturing process of LED fluorescent tubes, an automatic LED fluorescent tube gripping and loading device is usually used to grip and load the LED fluorescent tubes.

[0003] The existing automatic LED fluorescent tube gripping and loading device places the LED fluorescent tubes on a feeding trolley, which then moves the tubes to the gripping area for gripping. However, since the LED fluorescent tubes are usually stacked on the feeding trolley, they may move during the gripping process, resulting in misalignment and affecting the efficiency of subsequent gripping and loading, which is quite inconvenient.

[0004] Therefore, an automatic LED fluorescent tube grabbing and mounting device has been developed that can align LED fluorescent tubes before grabbing them, thus avoiding misalignment of LED fluorescent tubes and affecting the tube mounting efficiency. Summary of the Invention

[0005] To overcome the shortcomings of existing automatic LED fluorescent tube gripping and mounting devices, where LED fluorescent tubes may move during gripping, resulting in misalignment and affecting subsequent gripping and mounting efficiency, this invention provides an automatic LED fluorescent tube gripping and mounting device that can align LED fluorescent tubes before gripping, thus avoiding misalignment and affecting mounting efficiency.

[0006] The technical solution is as follows: An automatic LED fluorescent tube gripping device includes a translation slide, a lifting slide, a lifting frame, a bidirectional motor, a lead screw, a clamping arm, a receiving frame, a feeding trolley, LED fluorescent tubes, and an alignment mechanism. The left and right sides of the translation slide are slidably connected to the lifting slide, and the left and right sides of the lifting slide are slidably connected to the lifting frame. The middle of the lifting frame is connected to the bidirectional motor, and each output shaft of the bidirectional motor is connected to a lead screw with opposite thread directions. Each lead screw is threadedly connected to a clamping arm, which is slidably connected to the lifting frame. The upper rear side of the translation slide is connected to the receiving frame, and the lower part of the lifting slide is equipped with a feeding trolley on which multiple LED fluorescent tubes are placed. The translation slide is equipped with an alignment mechanism that can align the LED fluorescent tubes.

[0007] As an improvement to the above solution, a buffer pad is also included, with buffer pads connected to the lower sides of the clamping arms that are close to each other.

[0008] As an improvement to the above solution, the alignment mechanism for aligning LED fluorescent tubes includes a first support frame, a clamping frame, a first rotating frame, and a first spring. The first support frame is connected to the left and right sides of the translation slide, which are close to each other. A clamping frame is slidably connected to each of the first support frames. Two first rotating frames are rotatably connected to the upper front part of the translation slide. Both first rotating frames are in contact with the lifting slide and are rotatably connected to the adjacent clamping frame. A first spring connects the front and rear parts of the clamping frame to the connected first support frame. At this time, the first spring is in a stretched state. The lifting slide disengages from the first rotating frame, causing the first spring to rebound, which drives the clamping frames to slide closer to each other on the first support frame, bringing the clamping frames into contact with the LED fluorescent tubes.

[0009] As an improvement to the above solution, a buffer mechanism for cushioning the feeding car is also included. The buffer mechanism includes a support block, a damper, a second spring, and a buffer frame. The support block is connected to the front side of the middle of the translation slide. Dampers are connected to the front sides of both the left and right sides of the support block. The buffer frame is slidably connected between the dampers. The second spring is connected between the dampers and the buffer frame. When the feeding car is pushed to the translation slide, the feeding car contacts the buffer frame, and the buffer frame is squeezed and moves backward toward the support block on the damper. The second spring is squeezed and contracted.

[0010] As an improvement to the above solution, an anti-slip mechanism is also included to prevent the LED fluorescent tube from slipping. The anti-slip mechanism includes a sliding rod, a third spring, and a silicone head. Multiple sliding rods are slidably connected to the lower part of the clamping arm. A third spring is connected between each sliding rod and the clamping arm. A silicone head is connected to each sliding rod. The sliding rod passes through adjacent buffer pads. When the buffer pads are close to each other to clamp the LED fluorescent tube, part of the silicone head enters the LED fluorescent tube, and part of the silicone head contacts the edge of the LED fluorescent tube, causing the sliding rod to slide on the clamping arm and the third spring to stretch.

[0011] As an improvement to the above solution, a clamping mechanism for clamping the feeding cart is also included. The clamping mechanism includes a servo motor, a synchronous frame, a moving frame, and support arms. The servo motor is connected to the upper rear side of the buffer frame, and the synchronous frame is connected to the output shaft of the servo motor. Support arms are connected to both the left and right sides of the buffer frame, and the moving frames are slidably connected to the support arms. The moving frames are movably connected to the synchronous frame. When the servo motor is started, the synchronous frame is rotated, causing the moving frames to slide closer to each other on the support arms, so that the moving frames contact the feeding cart.

[0012] As an improvement to the above solution, an emptying mechanism is also included for clearing the LED fluorescent tubes on the receiving rack. The emptying mechanism includes a second rotating frame, a second support frame, a third rotating frame, a sliding frame, a third support frame, a fourth spring, and a sliding sleeve. The second rotating frame is rotatably connected to both sides of the receiving rack. The second support frame is connected to the rear of the translation slide. The third rotating frame is rotatably connected to the second support frame. The second rotating frame is in contact with the third rotating frame. The third support frame is connected to the upper left rear of the translation slide. The sliding frame is slidably connected to the third support frame. The sliding frame is movably connected to the third rotating frame. The fourth spring is connected between the left and right sides of the third support frame and the sliding frame. The sliding sleeve is connected to the lower left side of the lifting slide. The sliding frame is slidably connected to the sliding sleeve. When the lifting slide moves forward, it drives the sliding sleeve to move forward, causing the sliding frame to move forward on the third support frame. The fourth spring is compressed and contracted, causing the sliding frame to push the third rotating frame to rotate, which in turn causes the third rotating frame to push the second rotating frame to rotate and tilt.

[0013] As an improvement to the above solution, a stopping mechanism for controlling the lifting frame to stop moving is also included. The stopping mechanism includes a connecting frame, a contact frame, and a touch switch. The connecting frame is connected between the front and rear sides of the lifting frame. The contact frame is slidably connected to the connecting frame. The touch switch is connected to the lower side of the middle of the connecting frame. The lower side of the touch switch contacts the contact frame. The contact frame contacts the LED fluorescent tube. Then the contact frame moves upward on the connecting frame. When the buffer pad is flush with the uppermost LED fluorescent tube, the contact frame triggers the touch switch to stop the lifting frame from moving.

[0014] The present invention has the following advantages: 1. When the lifting slide moves backward, the lifting slide disengages from the first rotating frame, causing the first spring to rebound and drive the clamping frame to slide closer to each other on the first support frame, so that the clamping frame contacts the LED fluorescent tube. This achieves the effect of aligning the LED fluorescent tube before gripping, avoiding the LED fluorescent tubes being misaligned, which would affect the tube loading efficiency.

[0015] 2. In this invention, when the feeding trolley is pushed to the translation slide, the feeding trolley contacts the buffer frame, and the buffer frame is squeezed and moves backward toward the support block under damping. The second spring is compressed and contracted, which achieves the effect of buffering the feeding trolley and preventing the LED fluorescent tube from falling due to the feeding trolley hitting the translation slide.

[0016] 3. When the LED fluorescent tube is clamped by the buffer pads coming close together, part of the silicone head enters the LED fluorescent tube and part of the silicone head contacts the edge of the LED fluorescent tube, causing the slide bar to slide on the clamping arm. The third spring is stretched, which achieves the effect of fixing the LED fluorescent tube and preventing the LED fluorescent tube from slipping and being damaged.

[0017] 4. This invention activates the servo motor after the feeding cart contacts the buffer frame, causing the synchronous frame to rotate. This allows the moving frame to slide closer to the support arm, bringing the moving frame into contact with the feeding cart. This achieves the goal of clamping the feeding cart and preventing its movement from affecting the gripping effect on the LED fluorescent tubes.

[0018] 5. The present invention uses a sliding frame to push the third rotating frame to rotate, which in turn pushes the second rotating frame to rotate and tilt, so that the LED fluorescent tubes on the receiving frame can be moved to the next processing area. This achieves the effect of clearing the LED fluorescent tubes on the receiving frame and improving the efficiency of LED fluorescent tube loading. Attached Figure Description

[0030] The above-described solution will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of this application. The implementation conditions used in the embodiments may be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are generally those in routine experiments.

[0031] An automatic LED fluorescent tube gripping device, such as Figure 1 and Figure 2 As shown, the system includes a translation slide 1, a lifting slide 2, a lifting frame 3, a bidirectional motor 4, a lead screw 5, a clamping arm 6, a buffer pad 7, a receiving frame 8, a feeding trolley 9, LED fluorescent tubes 10, and an alignment mechanism 11. The lifting slide 2 is slidably connected between the left and right sides of the translation slide 1. The lifting frame 3 is slidably connected between the left and right sides of the lifting slide 2. The bidirectional motor 4 is connected to the middle of the lifting frame 3. Lead screws 5 are connected to the output shafts of the bidirectional motor 4. The threads on the lead screws 5 are in opposite directions. Clamping arms 6 are threadedly connected to the lead screws 5. The clamping arms 6 are slidably connected to the lifting frame 3. Buffer pads 7 are connected to the lower sides of the clamping arms 6 that are close to each other. The receiving frame 8 is connected to the upper rear side of the translation slide 1. The feeding trolley 9 is located at the lower part of the lifting slide 2. Multiple LED fluorescent tubes 10 are placed on the feeding trolley 9. The alignment mechanism 11 is located on the translation slide 1.

[0032] like Figure 1 , Figure 3 and Figure 4As shown, the alignment mechanism 11 includes a first support frame 111, a clamping frame 112, a first rotating frame 113, and a first spring 114. The first support frame 111 is connected to the left and right sides of the translation slide 1, which are close to each other. The clamping frame 112 is slidably connected to the first support frame 111. The left and right first rotating frames 113 are rotatably connected to the upper front part of the translation slide 1. The first rotating frames 113 are in contact with the lifting slide 2. The first rotating frames 113 are rotatably connected to the adjacent clamping frame 112. The clamping frame 112 is connected to the first support frame 111 at both the front and rear parts, and the first spring 114 is connected between them. At this time, the first spring 114 is in a stretched state.

[0033] When using this invention, first, place the translation slide 1 in the area where the LED fluorescent tube 10 is automatically gripped. Then, push the feeding trolley 9 to the translation slide 1 so that the LED fluorescent tube 10 is below the lifting slide 2. Next, start the lifting slide 2 to move the lifting frame 3 downward, causing the clamping arms 6 to move downward. When the buffer pad 7 is flush with the uppermost LED fluorescent tube 10, start the bidirectional motor 4 to rotate the lead screw 5, causing the clamping arms 6 to move closer together, so that the buffer pad 7 contacts the uppermost LED fluorescent tube 10 and clamps it. Then, control the lifting frame 3 to move upward, and start the translation slide 1 again to move the lifting slide 2 backward to above the receiving rack 8. Then, move the lifting frame 3 downward to move the clamping arms 6 away from each other, so that the LED fluorescent tube 10 moves onto the receiving rack 8. Finally, move the lifting slide 2 forward. The above operation is repeated to move the LED fluorescent tubes 10 layer by layer to the receiving rack 8, so as to realize the automatic gripping of the LED fluorescent tubes 10. When the lifting slide 2 moves backward, the lifting slide 2 disengages from the first rotating frame 113, causing the first spring 114 to rebound, driving the clamping frame 112 to slide closer to each other on the first support frame 111, so that the clamping frame 112 contacts the LED fluorescent tube 10. When the lifting slide 2 moves forward to reset, the lifting slide 2 squeezes the first rotating frame 113 to rotate, so that the first rotating frame 113 pulls the clamping frame 112 to slide away from each other on the first support frame 111, and the first spring 114 is stretched, which facilitates the clamping of the LED fluorescent tubes 10. This can align the LED fluorescent tubes 10 before gripping, and avoid the LED fluorescent tubes 10 being misaligned, which would affect the efficiency of the tube loading.

[0034] like Figure 1 and Figure 5As shown, it also includes a buffer mechanism 12, which includes a support block 121, a damper 122, a second spring 123 and a buffer frame 124. The support block 121 is connected to the front side of the middle part of the translation slide 1. The dampers 122 are connected to the front sides of both the left and right parts of the support block 121. The buffer frame 124 is slidably connected between the dampers 122. The second spring 123 is connected between each damper 122 and the buffer frame 124.

[0035] Using the buffer mechanism 12 of this device, the feeding trolley 9 can be buffered. When the feeding trolley 9 is pushed to the translation slide 1, the feeding trolley 9 contacts the buffer frame 124, and the buffer frame 124 is squeezed and moves backward close to the support block 121 on the damping 122. The second spring 123 is compressed and then rebounds through the second spring 123, pushing the buffer frame 124 to slowly return to its original position, so that the feeding trolley 9 moves forward to below the lifting slide 2. This can buffer the feeding trolley 9 and prevent the feeding trolley 9 from hitting the translation slide 1 and causing the LED fluorescent tube 10 to fall.

[0036] like Figure 1 , Figure 6 and Figure 7 As shown, it also includes an anti-slip mechanism 13, which includes a slide rod 131, a third spring 132 and a silicone head 133. Multiple slide rods 131 are slidably connected to the lower part of the clamping arm 6. Each slide rod 131 is connected to the clamping arm 6 by a third spring 132. Each slide rod 131 is connected to a silicone head 133. Each slide rod 131 passes through an adjacent buffer pad 7.

[0037] Using the anti-slip mechanism 13 of this device, the LED fluorescent tube 10 can be prevented from slipping. When the buffer pads 7 are close together to clamp the LED fluorescent tube 10, part of the silicone head 133 enters the LED fluorescent tube 10, and part of the silicone head 133 contacts the edge of the LED fluorescent tube 10, so that the slide bar 131 slides on the clamping arm 6 and the third spring 132 is stretched, thereby fixing the LED fluorescent tube 10 and preventing the LED fluorescent tube 10 from slipping and being damaged.

[0038] like Figure 1 and Figure 8 As shown, it also includes a clamping mechanism 14, which includes a servo motor 141, a synchronization frame 142, a moving frame 143, and a support arm 144. The servo motor 141 is connected to the upper rear side of the buffer frame 124, and the synchronization frame 142 is connected to the output shaft of the servo motor 141. The support arms 144 are connected to both the left and right sides of the buffer frame 124, and the moving frame 143 is slidably connected to each support arm 144. The moving frame 143 is movably connected to the synchronization frame 142.

[0039] Using the clamping mechanism 14 of this device, the feeding carriage 9 can be clamped. When the feeding carriage 9 comes into contact with the buffer frame 124, the servo motor 141 is started, which drives the synchronous frame 142 to rotate, so that the moving frame 143 slides on the support arm 144 and moves closer to each other, so that the moving frame 143 comes into contact with the feeding carriage 9, thereby clamping the feeding carriage 9 and preventing the movement of the feeding carriage 9 from affecting the gripping of the LED fluorescent tube 10.

[0040] like Figure 1 and Figure 9 As shown, it also includes a clearing mechanism 15, which includes a second rotating frame 151, a second support frame 152, a third rotating frame 153, a sliding frame 154, a third support frame 155, a fourth spring 156, and a sliding sleeve 157. The receiving frame 8 is rotatably connected to the second rotating frame 151 on both the left and right sides. The rear of the translation slide 1 is connected to the second support frame 152, and the third rotating frame 153 is rotatably connected to the second support frame 152. The second rotating frame 151 is in contact with the third rotating frame 153. The upper left rear side of the translation slide 1 is connected to the third support frame 155, and the sliding frame 154 is slidably connected to the third support frame 155. The sliding frame 154 is movably connected to the third rotating frame 153. The left and right sides of the third support frame 155 are connected to the sliding frame 154 by the fourth spring 156. The lower left side of the lifting slide 2 is connected to the sliding sleeve 157, and the sliding frame 154 is slidably connected to the sliding sleeve 157.

[0041] Using the emptying mechanism 15 of this device, the LED fluorescent tubes 10 on the receiving rack 8 can be emptied. When the lifting slide 2 moves forward, it drives the sliding sleeve 157 to move forward, causing the sliding frame 154 to move forward on the third support frame 155. The fourth spring 156 is compressed and contracted, causing the sliding frame 154 to push the third rotating frame 153 to rotate, which in turn pushes the second rotating frame 151 to rotate and tilt, moving the LED fluorescent tubes 10 on the receiving rack 8 to the next processing area. This effectively empties the LED fluorescent tubes 10 on the receiving rack 8, improving the efficiency of LED fluorescent tube loading. When the lifting slide 2 moves backward, the sliding sleeve 157 slides backward on the sliding frame 154. The fourth spring 156 rebounds, causing the sliding frame 154 to reset, allowing the second rotating frame 151 to rotate and be placed on the second support frame 152 for easy reception of LED fluorescent tubes 10.

[0042] like Figure 1 and Figure 10As shown, it also includes a stop mechanism 16, which includes a connecting frame 161, a contact frame 162 and a touch switch 163. The connecting frame 161 is connected between the front and rear sides of the lifting frame 3. The contact frame 162 is slidably connected to the connecting frame 161. The touch switch 163 is connected to the lower side of the middle part of the connecting frame 161. The lower side of the touch switch 163 is in contact with the contact frame 162.

[0043] Using the stop mechanism 16 of this device, the lifting frame 3 can be controlled to stop moving. When the lifting frame 3 moves downward, it drives the connecting frame 161 to move downward, so that the contact frame 162 contacts the LED fluorescent tube 10. Then the contact frame 162 moves upward on the connecting frame 161. When the buffer pad 7 is flush with the uppermost LED fluorescent tube 10, the contact frame 162 triggers the touch switch 163 to stop the lifting frame 3 from moving. This achieves the function of controlling the lifting frame 3 to stop moving, which facilitates the gripping of LED fluorescent tubes 10 at different heights.

[0044] The technical principles of the embodiments of the present invention have been described above with reference to specific examples. These descriptions are merely for explaining the principles of the embodiments of the present invention and should not be construed as limiting the scope of protection of the embodiments of the present invention in any way. Based on the explanation herein, those skilled in the art can conceive of other specific embodiments of the present invention without creative effort, and these embodiments will all fall within the scope of protection of the embodiments of the present invention.

When the buffer pads (7) are close to each other to clamp the LED fluorescent tube (10), a part of the silicone head (133) enters the LED fluorescent tube (10) and a part of the silicone head (133) contacts the edge of the LED fluorescent tube (10), so that the slide rod (131) slides on the clamping arm (6) and the third spring (132) is stretched.

5. The automatic LED fluorescent tube gripping device as described in claim 4, characterized in that, It also includes a stop mechanism (16) for controlling the lifting frame (3) to stop moving. The stop mechanism (16) includes a connecting frame (161), a contact frame (162) and a touch switch (163). The connecting frame (161) is connected between the front and rear sides of the lifting frame (3). The contact frame (162) is slidably connected to the connecting frame (161). The touch switch (163) is connected to the lower side of the middle of the connecting frame (161). The lower side of the touch switch (163) contacts the contact frame (162). The contact frame (162) contacts the LED fluorescent tube (10). Then the contact frame (162) moves upward on the connecting frame (161). When the buffer pad (7) is flush with the uppermost LED fluorescent tube (10), the contact frame (162) triggers the touch switch (163) to stop the lifting frame (3) from moving.
