Description

Technical Field

[0001] The utility model relates to the technical field of lamp tube manufacturing, in particular to an improved temporary material placing rack for unqualified products. Background Art

[0002] LED tube, full name is light emitting diode tube, is a lighting device that uses LED (Light Emitting Diode) as a light source. It uses LED chips to emit light and spreads and diffuses the light through a specific tube structure to achieve lighting effects.

[0003] After the LED lamp tubes are assembled, they need to be powered on for testing and those that cannot work properly, i.e., unqualified products, need to be removed. This is usually done by automated equipment, which includes a feeding mechanism, a conveyor belt with a temporary material discharge structure (on which a material guide ramp is tilted) and a material ejection mechanism, a testing mechanism, and a material discharge mechanism. The feeding mechanism places the assembled lamp tubes on the conveyor belt. When the lamp tubes reach the testing position, the conveyor belt stops moving. The testing mechanism performs a power-on test on the lamp tubes. If the lamp tubes are not lit, the mechanism lifts up the unqualified products through the lifting cylinder of the lifting mechanism. The upper end of the lamp tubes is aligned with the material guide ramp. The arc block arranged at the end for rotation contacts and finally moves to the top of the arc block. During this process, the arc block rotates relative to the guide inclined plate due to the squeezing of the lamp tube. When the lamp tube moves to the top of it, the arc block returns to its original position due to its own gravity. At this time, as the ejecting cylinder moves downward, the lower end of the lamp tube contacts the upper end of the arc block and separates from the ejecting cylinder. The lamp tube finally moves downward along the inclined surface of the guide inclined plate and contacts the stopper arranged at the other end of the guide inclined plate to form a block, thereby causing unqualified products to stay on the guide inclined plate. The existing temporary discharge structure has the following problems:

[0004] First, since only one material guide inclined plate is provided, the temporary storage capacity of the temporary material discharge structure is small, which easily causes the operator to frequently perform material discharge operations, and the overall material discharge interval is short, which is troublesome;

[0005] Second, when unloading the unqualified lamp tubes on the guide ramp, since the lamp tubes are laid obliquely on the guide ramp, it is necessary to take down the lamp tubes one by one or manually take down the lamp tubes together, which makes unloading more troublesome. Therefore, the present application provides an improved temporary material rack for unqualified products to meet the needs. Utility Model Content

[0006] The purpose of the present application is to provide an improved temporary unqualified product discharge rack, which is used to solve the technical problems that the existing temporary discharge structure requires frequent unloading and the unloading is troublesome.

[0007] To achieve the above-mentioned purpose, the present application provides the following technical solutions: an improved temporary material placing rack for unqualified products, comprising two limit baffles which are arranged opposite to each other and have mounting seats fixed on the outer walls, wherein a first material guide inclined plate is arranged obliquely downward on both limit baffles, and an arc block is arranged on the left side of the first material guide inclined plate, and the upper right end portion of the arc block is rotatably connected to the upper left end portion of the first material guide inclined plate, and further comprising a second material guide inclined plate and a third material guide inclined plate which are arranged obliquely downward, wherein the second material guide inclined plate and the third material guide inclined plate are inclined in opposite directions, and the third material guide inclined plate is inclined in opposite directions. The material inclined plate is inclined in the same direction as the first material guide inclined plate, and an arc-shaped guide plate is provided on one end of the third material guide inclined plate and the second material guide inclined plate located at a high position. The high end and the bottom end of the second material guide inclined plate are respectively arranged close to the bottom end of the first material guide inclined plate and the high end of the third material guide inclined plate, and a downwardly protruding arc-shaped material receiving plate is fixed to the bottom end of the third material guide inclined plate, and a stopper is fixed to the upper end of the arc-shaped material receiving plate, and the upper end of the stopper is located above the bottom end of the third material guide inclined plate, and an elastic buffer belt is arranged in the material receiving groove of the arc-shaped material receiving plate near the feed port.

[0008] As a preferred implementation manner in this embodiment, the first material guide inclined plate, the second material guide inclined plate and the third material guide inclined plate are each provided with a deceleration unit for reducing the speed of the LED lamp tube when it detaches from the first material guide inclined plate, the second material guide inclined plate and the third material guide inclined plate.

[0009] As a preferred implementation manner in this embodiment, the damping unit includes a first damping member, which includes a plurality of first elastic damping ridges, and the plurality of first elastic damping ridges are evenly distributed on the acceleration sections of the first material guide inclined plate, the second material guide inclined plate and the third material guide inclined plate.

[0010] As a preferred implementation manner in this embodiment, it also includes a second damping member, which includes a plurality of second elastic damping ridges arranged at equal intervals, and the plurality of second elastic damping ridges are all arranged close to the bottom ends of the first material guide inclined plate, the second material guide inclined plate and the third material guide inclined plate.

[0011] As a preferred implementation in this embodiment, the second elastic damping convex strip includes a columnar elastic sleeve, and an annular protrusion is provided on the elastic sleeve. The elastic sleeve is communicated with the inner cavity of the annular protrusion and both are filled with non-Newtonian fluid. The thickness of the annular protrusion is smaller than the thickness of the elastic sleeve.

[0012] As a preferred implementation manner in this embodiment, one of the two mounting seats arranged opposite to each other is provided with a threaded barrel, and the other mounting seat is rotatably provided with a threaded rod.

[0013] In summary, the technical effects and advantages of the utility model are:

[0014] The utility model has a reasonable structure. The temporary material discharge structure is provided with a plurality of material guiding inclined plates, which can increase the material storage capacity, reduce the material discharge frequency of the operator, extend the overall material discharge interval time, and reduce the labor intensity. At the same time, an arc-shaped material receiving plate with an elastic buffer belt is also provided, which can make the lamp tubes automatically form a stack, without the need for manual stacking, thereby reducing the labor intensity. At the same time, multiple lamp tubes can be removed at one time, thereby improving the material discharge efficiency. The provision of the elastic buffer belt can reduce the descending height of the lamp tube, thereby preventing the lamp tube from being damaged by collision due to excessive descending speed in the receiving groove of the arc-shaped material receiving plate.

[0015] In the utility model, a first retarding member and a second assembly member are provided to form a retarding unit, so as to prevent the final separation speed of the lamp tube from being too high and causing collision damage;

[0016] In the utility model, the second elastic damping convex strip includes an elastic sleeve with an annular protrusion, and the elastic sleeve is filled with a non-Newtonian fluid. Even when the speed of the lamp tube moving on the material guide inclined plate is reduced to a very small speed or even no speed, the lamp tube can eventually pass over the upper end of the elastic sleeve and move downward along the inclined surface through the gravity of the lamp tube itself, which can effectively prevent the lamp tube from staying on the material guide inclined plate due to the damping effect of the second damping member. At the same time, the second elastic damping convex strip of this structure is conducive to minimizing the detachment speed of the lamp tube. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example: Reference Figure 1-2 The improved temporary unqualified product placing rack shown in the figure comprises two limit baffles 1 which are arranged opposite to each other and have mounting seats 4 fixed on the outer walls, the two limit baffles 1 are both provided with a first material guide inclined plate 2 which is inclined downwardly, and an arc block 15 is provided on the left side of the first material guide inclined plate 2, the upper right end of the arc block 15 is rotatably connected to the upper left end of the first material guide inclined plate 2, and further comprises a second material guide inclined plate 3 and a third material guide inclined plate 5 which are arranged obliquely downwardly, the second material guide inclined plate 3 and the third material guide inclined plate 5 are inclined in opposite directions, and the third material guide inclined plate 5 is inclined to the first material guide inclined plate 2. The material inclined plates 2 are inclined in the same direction, and an arc-shaped guide plate 10 is provided on one end of the third material guide inclined plate 5 and the second material guide inclined plate 3 located at a high position. The high end and the bottom end of the second material guide inclined plate 3 are respectively arranged close to the bottom end of the first material guide inclined plate 2 and the high end of the third material guide inclined plate 5, and a downwardly protruding arc-shaped material receiving plate 6 is fixed to the bottom end of the third material guide inclined plate 5, and a stopper 7 is fixed to the upper end of the arc-shaped material receiving plate 6, and the upper end of the stopper 7 is located above the bottom end of the third material guide inclined plate 5, and an elastic buffer belt 17 is arranged in the material receiving groove of the arc-shaped material receiving plate 6 near the feed port.

[0024] When the lamp tube is transported to the first material guide inclined plate 2 by the lifting cylinder, the lamp tube will move downward along the inclined surface of the first material guide inclined plate 2, and the lamp tube will pass through the second material guide inclined plate 3 and the third material guide inclined plate 5 in turn and finally move to the elastic buffer belt 17 on the arc receiving plate 6 (the elastic buffer belt 17 can reduce the descending height of the lamp tube to prevent the lamp tube from being damaged by collision due to too fast descending speed in the receiving groove of the arc receiving plate 6). As more and more lamp tubes are on the elastic buffer belt 17, the elastic buffer belt 17 extends downward under the action of the gravity of the lamp tube, and finally makes the lower end of the elastic buffer lamp belt 17 contact with the inner wall of the arc receiving plate 6. When multiple lamp tubes are piled up on the arc receiving plate 6, the subsequent lamp tubes will be laid obliquely on the third material guide inclined plate 5, The second material guide inclined plate 3 is on the first material guide inclined plate 2. By setting up multiple material guide inclined plates, the temporary storage capacity of the lamp tubes can be increased, the material unloading frequency of the operator can be reduced, the overall material unloading interval time can be extended, and the labor intensity can be reduced. At the same time, an arc-shaped material receiving plate 6 is set. The lamp tubes moving obliquely downward will move to the arc-shaped material receiving plate 6 and form a pile. The operator can directly remove the piled lamp tubes at one time. After removal, the remaining lamp tubes on the material guide inclined plate will move to the accommodating groove of the arc-shaped material receiving plate 6 to form a pile. After the pile is full, they are removed at one time until all the lamp tubes on the temporary material discharge structure are removed. Since the lamp tubes are automatically piled up on the arc-shaped material receiving plate 6, there is no need for manual stacking, which reduces labor intensity. At the same time, multiple lamp tubes can be removed at one time, thereby improving the unloading efficiency.

[0025] It should be noted that: 1. The inclination angles of the first material guide inclined plate 2, the second material guide inclined plate 3 and the third material guide inclined plate 5 are set at no more than 20°. If the inclination angle is too large, it is easy to cause the lamp tube to descend too quickly, resulting in a more violent collision with the arc guide plate 10 (which may easily damage the lamp tube); 2. The two arc material receiving plates 6 are connected to the corresponding third material guide inclined plate 5 at one end through the rotating shaft 16. Since the conveyor belt will vibrate during operation, and when the lamp tube falls into the material receiving groove, it will collide with the arc material receiving plate 6, which will cause the arc material receiving plate 6 to slide and shake, which is conducive to the subsequent lamp tubes to be evenly stacked in the material receiving groove; 3. The arc material receiving plate can be set to a U-shaped structure, a V-shaped structure and other shapes; 4. Its material guide inclined plate can be set to multiple, which can be four or five, and is not limited to three.

[0026] As a preferred implementation in this embodiment, Figure 1 As shown, the first material guide inclined plate 2 , the second material guide inclined plate 3 and the third material guide inclined plate 5 are all provided with a slowing unit for reducing the speed of the LED lamp tube when it leaves the first material guide inclined plate 2 , the second material guide inclined plate 3 and the third material guide inclined plate 5 .

[0027] Although the speed of the lamp tube can be changed by the tilt angle, for a longer material guide ramp (a longer material guide ramp can further increase the storage capacity), even if the tilt angle is very small, the speed after it detaches from the material guide ramp will be very high. Therefore, a slowdown unit is provided to prevent the final detachment speed of the lamp tube from being too high and causing damage.

[0028] As a preferred implementation in this embodiment, Figure 1 As shown, the damping unit includes a first damping member 11, and the first damping member 11 includes a plurality of first elastic damping convex strips, and the plurality of first elastic damping convex strips are evenly distributed on the acceleration sections of the first material guide inclined plate 2, the second material guide inclined plate 3 and the third material guide inclined plate 5.

[0029] The first damping member 11 is used to evenly reduce the speed of the lamp tube at various locations on the material guiding inclined plate, which is beneficial for maintaining the speed of the lamp tube on the material guiding inclined plate within a certain range.

[0030] It should be noted that the first elastic damping convex strip is made of rubber material and has a good damping effect.

[0031] As a preferred implementation in this embodiment, Figure 1 As shown, it also includes a second damping member 12, which includes a plurality of second elastic damping convex strips arranged at equal intervals, and the plurality of second elastic damping convex strips are all arranged near the bottom ends of the first material guide inclined plate 2, the second material guide inclined plate 3 and the third material guide inclined plate 5.

[0032] The purpose is to decelerate the lamp tubes before they leave the guide ramp, so that the speed of the lamp tubes when leaving the guide ramp is very small, which can effectively avoid the lamp tubes from violently colliding with the arc guide plate 10 and causing damage to the lamp tubes.

[0033] It should be noted that, through the cooperation of the first buffer member 11 and the second buffer member 12, the speed at which the lamp tube separates from the material guide inclined plate can be effectively reduced to a reasonable range, which can effectively avoid collision damage.

[0034] As a preferred implementation in this embodiment, Figure 3 As shown, the second elastic damping convex strip includes a columnar elastic sleeve 13, and an annular protrusion 14 is arranged on the elastic sleeve 13. The elastic sleeve 13 and the annular protrusion 14 are connected in inner cavity and are both filled with non-Newtonian fluid. The thickness of the annular protrusion 14 is less than the thickness of the elastic sleeve 13.

[0035] The second elastic damping convex strip is composed of an elastic sleeve filled with a non-Newtonian fluid. Even when the speed of the lamp tube moving on the material guide inclined plate is reduced to a very small speed or even to no speed, the elastic sleeve 13 protruding from the upper end surface of the material guide inclined plate can be squeezed by the lamp tube's own gravity. The upper end of the elastic sleeve 13 deforms downward, and the annular protrusion 14 expands outward, and finally the lamp tube passes over the upper end of the elastic sleeve 13 and moves downward along the inclined surface, which can effectively prevent the lamp tube from staying on the material guide inclined plate due to the damping effect of the second damping member 12. At the same time, the second elastic damping convex strip of this structure is conducive to minimizing the detachment speed of the lamp tube.

[0036] It should be noted that, first, the first material guide inclined plate 2, the second material guide inclined plate 3 and the third material guide inclined plate 5 are all provided with a accommodating cavity for accommodating the second elastic damping convex strip; second, the thickness of the annular protrusion 14 is less than the thickness of the elastic sleeve 13, so that after the elastic sleeve 13 is squeezed, the annular protrusion 14 is more likely to deform, so that the lamp tube can be separated from the material guide inclined plate by its own gravity without the action of initial velocity.

[0037] As a preferred implementation in this embodiment, Figure 1 As shown, one of the two mounting seats 4 arranged opposite to each other is provided with a threaded barrel 8, and the other mounting seat 4 is rotatably provided with a threaded rod 9.

[0038] During installation, conveyor belts of different widths can be installed by rotating the screw rod 9 to adjust the distance between the two mounting seats 4 .

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
