DETAILED DESCRIPTION

[0023] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0024] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0025] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directional words are not used to limit the present invention.

[0026] In order to solve the problem in the prior art that the quartz tube feeding trolley cannot be automatically opened and locked and has poor performance, the present application provides an auxiliary feeding device.

[0027] like Figure 1 and Figure 2 As shown, the auxiliary feeding device in the present application includes a vehicle body component 10, at least one clamping component 20, a support component 30 and a transmission component 40. The clamping component 20 has a clamping space, and at least a part of the clamping component 20 is movably arranged on the vehicle body component 10 to adjust the size of the clamping space; the support component 30 is arranged on the vehicle body component 10, and at least a part of the support component 30 can move in the vertical direction relative to the vehicle body component 10, and the support component 30 and the clamping component 20 are arranged at intervals in the vertical direction; one end of the transmission component 40 is connected to the support component 30, and the other end of the transmission component 40 is connected to the clamping component 20, so that the support component 30 can drive the clamping component 20 to move through the transmission component 40.

[0028] When using the auxiliary feeding device in the present application, since the auxiliary feeding device has a support assembly 30, the quartz tube 50 can be placed through the support assembly 30. In addition, after the quartz tube 50 is placed on the support assembly 30, the support assembly 30 is subjected to the gravity of the quartz tube 50 and moves downward. At this time, the support assembly 30 can drive the clamping assembly 20 to move through the transmission assembly 40, and make the clamping space smaller, so that the quartz tube 50 can be automatically locked. In the hanging process, the quartz tube 50 placed on the support assembly 30 is slowly lifted, and the gravity of the quartz tube 50 received by the support assembly 30 is gradually reduced and the clamping assembly 20 is driven by the transmission assembly 40 to move in the direction of the clamping space becoming larger, so that the clamping assembly 20 can be slowly loosened, thereby ensuring that the quartz tube 50 can be lifted more easily. Therefore, the auxiliary feeding device in the present application can realize the automatic opening and clamping functions without adding additional power. Therefore, the auxiliary feeding device in the present application effectively solves the problem that the quartz tube feeding trolley in the prior art cannot be automatically opened and locked and has poor performance.

[0029] Specifically, the support assembly 30 in the present application has a material holding position and a material feeding position. When the support assembly 30 moves from the material holding position to the material feeding position, at least a portion of the support assembly 30 moves relative to the vehicle body assembly 10 in a direction close to the clamping assembly 20; the clamping assembly 20 has a clamping position and a loosening position. When the support assembly 30 is in the material holding position, all the clamping assemblies 20 are in the clamping position, and when the support assembly 30 is in the material feeding position, all the clamping assemblies 20 are in the loosening position. That is, in the present application, when there are multiple clamping assemblies 20, the multiple clamping assemblies 20 move simultaneously, and the movement trends of the multiple clamping assemblies 20 are the same, that is, the multiple clamping assemblies 20 move simultaneously in the direction in which the clamping space becomes larger, that is, they move from the clamping position to the loosening position; or the multiple clamping assemblies 20 move simultaneously in the direction in which the clamping space becomes smaller, that is, they move from the loosening position to the clamping position.

[0030] It should be noted that when the clamping assembly 20 is in the clamping position, the clamping space is at its minimum state, and in order to ensure that the quartz tube 50 can more easily enter or exit the clamping assembly 20, the contour of the clamping space is larger than the radial cross-sectional area of ​​the quartz tube. In short, the clamping space is still larger than the radial cross-sectional area of ​​the quartz tube.

[0031] In a specific embodiment of the present application, Figure 2As shown, for the specific structure of the support assembly 30, the support assembly 30 includes a support chassis 31 and at least one reset member 32. The support chassis 31 has an annular enclosure on the side facing the clamping assembly 20, and the support chassis 31 has a material receiving position and a material feeding position; the two ends of the reset member 32 are respectively connected to the support chassis 31 and the body assembly 10 to provide the support chassis 31 with a reset force to move from the material receiving position to the material feeding position. In the process of placing the quartz tube 50 on the support chassis 31 of the support assembly 30, since the support chassis 31 is provided with an annular enclosure, the annular enclosure can play a certain limiting role on the quartz tube 50, thereby ensuring the stability of the quartz tube 50 after being placed on the support chassis 31. At the same time, by providing the annular enclosure, it can also be ensured that the quartz tube 50 can be placed in the correct position, thereby ensuring that the clamping assembly 20 can clamp the quartz tube 50.

[0032] Optionally, the supporting chassis 31 may be a polytetrafluoroethylene chassis.

[0033] In the above embodiment, the reset member 32 can be a tension spring, and one end of the tension spring can be set on the body assembly by a screw. In addition, the support assembly 30 can have two tension springs, which are symmetrically arranged on both sides of the support chassis 31 relative to the transmission assembly 40, and the tension springs are located above the support chassis 31. In actual use, after the quartz tube 50 is placed on the support chassis 31, the support chassis 31 drives the transmission assembly 40 to move downward together, and the tension spring is stretched. In the process of the quartz tube 50 being lifted, the force acting on the support base plate by the quartz tube 50 gradually decreases, and the support base plate drives the transmission assembly 40 to move upward under the action of the reset force of the tension spring.

[0034] Preferably, if Figure 2 As shown, the support assembly 30 also includes a second guide rail 33 and a second slider 34 that cooperate with each other. The second guide rail 33 is arranged on the vehicle body assembly 10, and the second slider 34 is arranged on the support chassis 31 and can move along the second guide rail 33. In this way, the movement direction of the support chassis 31 can be limited by the cooperation of the second guide rail 33 and the second slider 34, so as to ensure that the support chassis 31 can move along the preset position under the action of the reset member 32, thereby ensuring the use performance of the auxiliary feeding device. Further preferably, the support assembly 30 is provided with two sets of second guide rails 33 and second sliders 34 that cooperate with each other, and for the setting positions of the two sets of second guide rails 33 and second sliders 34, the two sets of second guide rails 33 and second sliders 34 can be set corresponding to the positions of two tension springs. Moreover, in the present application, the setting directions of the second guide rail 33 and the tension spring are parallel to the vertical direction, so as to ensure that the support chassis 31 can move more smoothly in the vertical direction, and at the same time, such a setting can effectively prevent the tension spring from being deflected and ensure the service life of the tension spring.

[0035] Furthermore, in the process of placing the quartz tube 50, as the quartz tube 50 is placed on the supporting chassis 31, the supporting chassis 31 moves from the feeding position to the material holding position, and when the quartz tube 50 is completely placed on the supporting chassis 31, the supporting chassis 31 is in the material holding position. When the quartz tube 50 is not placed on the supporting chassis 31, the supporting chassis 31 is in the feeding position under the action of the tension spring. In actual use, as the quartz tube 50 is placed on the supporting chassis 31 and the quartz tube 50 is lifted, the supporting chassis 31 reciprocates in the vertical direction, so when the supporting chassis 31 moves to the material holding position, the supporting chassis 31 moves downward, and when the supporting chassis 31 moves to the feeding position, the supporting chassis 31 moves upward.

[0036] Alternatively, if Figure 1 and Figure 2 As shown, for the number of clamping assemblies 20 in the present application, there are at least two clamping assemblies 20, all of which are arranged at intervals in the vertical direction, and different clamping assemblies 20 are respectively connected to different positions of the transmission assembly 40. Of course, the specific number of clamping assemblies 20 can be adjusted according to the actual usage. And in order to ensure the clamping effect of the clamping assembly 20 on the quartz tube 50, the centers of the multiple clamping assemblies 20 and the center of the supporting chassis 31 can be located in the same straight line in the vertical direction. In other words, the centers of the clamping spaces of the multiple clamping assemblies 20 and the center of the annular enclosure of the supporting chassis 31 are located in the same straight line in the vertical direction, so as to ensure that the quartz tube 50 will not be deflected when it is clamped by the clamping assembly 20 after being placed on the supporting chassis 31.

[0037] In a specific embodiment of the present application, Figure 1 and Figure 2As shown, for the specific structure of the clamping assembly 20, the clamping assembly 20 includes two clamping parts symmetrically arranged with respect to the transmission assembly 40, and the clamping parts include a clamping arm 21, a first slide rail 22, a first slider 23 and a rotating connecting rod 24. The clamping arms 21 of the two clamping parts enclose a clamping space; the first slide rail 22 is arranged on the vehicle body assembly 10, and the length direction of the first slide rail 22 is perpendicular to the extension direction of the transmission assembly 40; the first slider 23 is movably arranged on the first slide rail 22 and can move along the first slide rail 22, and the first slider 23 is connected to the clamping arm 21; the two ends of the rotating connecting rod 24 are pivotally connected to the first slider 23 and the transmission assembly 40 respectively. By such arrangement, when the supporting chassis 31 drives the transmission assembly 40 to move in the vertical direction, since the two ends of the rotating connecting rod 24 are respectively pivotally connected to the first slider 23 and the transmission assembly 40, the angle between the transmission connecting rod and the first slide rail 22 changes during the movement of the transmission connecting rod with the transmission assembly 40, and the first slider 23 is driven to reciprocate along the first slide rail 22, so that the clamping arm 21 can move in the direction close to or away from the quartz tube 50, thereby realizing the adjustment of the size of the clamping space. Preferably, in order to reduce the scratching of the quartz tube 50 by the clamping arm 21 during the movement, the clamping arm 21 can be set to an arc shape close to the outer side wall of the quartz tube 50. In addition, it should be pointed out that in the present application, the movement form of the clamping arm 21 is approximately translation. Preferably, the outer surface of the clamping arm can be coated with a nylon pad.

[0038] Specifically, the transmission assembly 40 includes at least one transmission rod 41, which extends in the vertical direction and is connected to the support assembly 30 and the clamping assembly 20, respectively. Preferably, the transmission assembly 40 also includes a mounting plate 42, through which the transmission rod 41 is connected to the clamping assembly 20, and when there are multiple transmission rods 41, two adjacent transmission rods 41 are connected by the mounting plate 42. Of course, the specific structure of the transmission assembly 40 can also be changed according to actual usage, as long as it is ensured that the transmission assembly 40 can drive the clamping assembly 20 to move under the action of the support assembly 30. In addition, in this embodiment, when there are multiple clamping assemblies 20, the size of the angle between the clamping arm 21 and the transmission rod 41 can be the same, so as to ensure that the clamping space of the multiple clamping assemblies 20 is the same in size. In addition, by setting the axial direction of the transmission rod 41 to be parallel to the vertical direction, it can be ensured that the rotating rod can more easily drive the first slider 23 through the rotating connecting rod 24 when the support assembly 30 moves.

[0039] Specifically, the vehicle body assembly 10 includes a vehicle body 11 and a mounting frame 12, the mounting frame 12 is disposed on the vehicle body 11, and the clamping assembly 20 and the supporting assembly 30 are respectively disposed on the mounting frame 12. Preferably, the vehicle body 11 may be an automatic guided vehicle.

[0040] Optionally, the mounting frame 12 includes a plurality of vertical frames 121, and the plurality of vertical frames 121 enclose an installation space, and the support assembly 30 is arranged in the installation space. In this arrangement, the vertical frames 121 can play a guiding role in the process of placing the quartz cylinder 50. In addition, the overall stability of the body assembly 10 can be improved by providing the vertical frames 121.
