Description

Technical Field

[0001] The utility model relates to the technical field of spectroscope equipment, and particularly relates to a light source collection device for spectroscope equipment. Background Art

[0002] The spectroscope equipment includes a test platform, a blowing and blanking device, a guiding hose, a distribution device and a light source collection device. The light source collection device is provided with a plurality of collection grooves for collecting light sources. Multiple light sources to be tested are placed on the test platform for spectroscope tests in sequence. After the first light source completes the test, the distribution device first moves the end of the guiding hose above the collection groove corresponding to the first light source according to the test result. The blowing and blanking device blows the first light source from the test platform into the guiding tube. The first light source moves along the guiding hose to the end of the guiding hose, leaves the guiding hose from the end of the guiding hose, and falls into the corresponding collection groove. During this process, if the second light source has completed the test, in order to prevent distribution errors, the distribution device still needs to wait for the first light source to leave the guiding hose before moving the end of the guiding hose above the collection groove corresponding to the second light source. The blowing and blanking device needs to wait for the distribution device to complete the above operations before blowing the second light source on the test platform into the guiding hose. If the moving speed of the first light source in the guiding hose is slow, it will affect the overall distribution efficiency. Therefore, the spectroscope equipment generally allows the light source to move in the guiding hose at a relatively fast speed. Some spectroscope equipment is also equipped with an accelerating blanking device such as the one disclosed in the patent document CN203875029U. This device is provided with a blowing pipe at the test platform. After the blowing and blanking device blows the light source onto the guiding hose, the blowing pipe blows air at the light source in the guiding hose to accelerate the moving speed of the light source in the guiding hose, thereby improving the distribution efficiency. Since the moving speed of the light source in the guiding hose is fast, after the light source leaves the guiding hose, it will fall into the collection groove at a relatively fast speed and collide with the groove wall of the collection groove, easily damaging the light source. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide a light source collection device for spectroscope equipment, which can make the light source fall into the collection groove at a slower speed and is not easy to damage the light source.

[0004] To solve the above technical problem, the light source collection device for spectroscope equipment of the utility model is provided with a plurality of collection grooves, and a buffer pipe is provided for each collection groove. The buffer pipe is provided with a feeding port for the light source to enter the pipe, and a discharging port for discharging the light source entering the pipe. The discharging port is aligned with the collection groove. The buffer pipe has an inner wall for frictional contact with the light source entering the pipe to slow down the light source.

[0005] Furthermore, the buffer pipe is an inclined pipe.

[0006] Further, the buffer tube is provided with a turning section that collides with the light source entering the tube to decelerate and reverse the direction of the light source.

[0007] Further, a driving mechanism is provided to drive the buffer tube to move towards the discharge port against the outlet, so as to cause the light source staying on the tube wall to move away from the tube wall towards the discharge port under the action of inertia.

[0008] Further, the buffer tube is an inclined tube with its inlet facing upwards and its outlet facing downwards and aligned with the notch of the collection tank; the driving mechanism specifically drives the buffer tube to move horizontally, so that the light source staying on the inclined tube wall moves horizontally away from the inclined tube wall and moves obliquely downwards under the action of inertia and leaves the buffer tube from the outlet and drops into the collection tank.

[0009] Further, the length of the notch of the collection tank in the moving direction of the buffer tube is greater than the inner diameter of the buffer tube.

[0010] Further, it includes a horizontal slide rail, and the buffer tube is installed on the horizontal slide rail; the driving mechanism includes a motor, a crank and a connecting rod. The motor is drivingly connected to the crank. The connecting rod has a vertical chute at its starting end, and the crank is clamped into the vertical chute at the starting end of the connecting rod to connect the starting end of the connecting rod in this way. The end of the connecting rod is connected to the buffer tube. When the motor drives the crank to rotate, the crank slides vertically along the vertical chute of the connecting rod, and thus drives the buffer tube to move horizontally along the horizontal slide rail.

[0011] Further, the inner diameter of the buffer tube is 30 - 40 mm.

[0012] Further, the cross-section of the inner cavity of the buffer tube is rectangular.

[0013] Further, the inner wall of the buffer tube is specifically provided with a PET coating.

[0014] The light source enters the buffer tube from the inlet of the buffer tube. During the process of moving along the buffer tube, it is decelerated by friction with the inner wall of the buffer tube and leaves the buffer tube from the outlet at a slower speed and enters the collection tank. Even if it collides with the wall of the collection tank, it is not easily damaged. Description of the Drawings

[0022] The following further elaborates on the present invention in conjunction with specific embodiments.

[0023] The light source collection device for the spectroscopic equipment is shown in Figure 1 , including a mounting bracket 8. A collection box 7 is slidably mounted at the bottom of the mounting bracket 8. The collection box 7 can be pulled out forward, and after being pulled out, it is as shown in Figure 2 . Fifty collection hoppers 6 are mounted on the collection box 7, with 10 columns in 5 rows, a total of 50. Each collection hopper 6 is provided with 1 collection slot 1, and a label 60 is pasted at each collection slot 1. Two upper and lower mounting plates 5 are mounted on the mounting bracket 8. Fifty buffer tubes 2 are mounted on the two upper and lower mounting plates 5, with 10 columns in 5 rows, a total of 50. The buffer tubes 2 are made of non-metallic materials such as plastics. See Figure 3 . The upper pipe orifices 21 of the 50 buffer tubes 2 face upward, and the lower pipe orifices 22 face downward respectively and are aligned with the slot openings 10 of the collection slots 1 of the 50 collection hoppers 6. The buffer tubes 2 are inclined tubes bent backward. The upper section 201 thereof is an inclined section with the upper end forward and the lower end backward. The middle section 202 is a turning section 202, located between the upper and lower mounting plates 5. The lower section 203 is an inclined section with the upper end backward and the lower end forward. The inner inclined wall 20 of the buffer tube 2 is provided with a coating (not shown in the figure) for increasing wear resistance and friction coefficient, preferably a PET coating or a frosted coating. The cross-section of the inner cavity 200 of the buffer tube 2 is circular or rectangular, specifically preferably the rounded rectangle as shown in Figure 5 . The length L1 and width L2 of this rectangle are both the inner diameter of the buffer tube 2 and are both 30 mm to 40 mm; preferably, L1 is 35 mm and L2 is 40 mm. During use, the spectroscopic equipment performs spectroscopic tests on light sources with a size of 5 to 7 mm, and after the tests, the light sources are distributed to the corresponding buffer tubes 2 according to the test results. See Figure 3 . The upper pipe orifice 21 of the buffer tube 2 serves as the inlet. The light source 9 enters the tube from the upper pipe orifice 21 and falls onto the inclined inner wall 204 of the upper section 201 of the buffer tube 2. In this state, see Figure 4 . The force F received by the light source 9 is decomposed into an impact force F1 perpendicular to the inclined inner wall 204 and a deceleration force F2 parallel to the inclined inner wall 204. And the light source 9 is circular and can roll backward and downward along the inclined inner wall 204, consuming the impact energy and not being damaged due to hitting the inclined inner wall 204 of the upper section 201 of the buffer tube 2. See Figure 3, during the rolling process of the light source 9, it decelerates by rubbing against the inclined inner wall 204 of the buffer tube 2. Only after deceleration does it pass through the turning section 202 of the buffer tube 2 and collide with the inner wall 205 of the turning section 202. Therefore, it is not easily damaged and further decelerates in this way. After the collision, the light source 9 is guided by the turning section 202 to turn (i.e., the light source 9 changes direction), and rolls forward and downward along the inclined inner wall 206 of the lower section 203 of the buffer tube 2, and decelerates to a slower speed by rubbing against the inclined inner wall 206. The lower pipe opening 22 of the buffer tube 2 serves as the discharge port 22. The light source 9 is discharged from the lower pipe opening 22 of the buffer tube 2 to the outside of the buffer tube 2 at a slower speed and enters the corresponding notch 10 of the collection tank 1. Even if it collides with the wall of the collection tank 1, it is not easily damaged. After the operator finishes spectroscopy, as Figure 2 shown, pull the collection box 7 forward and then take out the light source that has fallen into the collection tank 1.

[0024] See Figure 3 , there may be dirt such as glue adhering to the light source 9. After decelerating by rubbing against the inclined inner wall 20 of the buffer tube 2, it may adhere to the inner wall 20 of the buffer tube 2, that is, stay on the inner wall 20 of the buffer tube 2. For this reason, see Figure 1 、 Figure 6 , a horizontal slide rail 4 in the front-rear direction is installed on the mounting frame 8 of this device; the upper and lower mounting plates 5 are slidably installed on the slide rail 4 and are installed on the mounting frame 8 in this way. This device also has a driving mechanism 3 to drive the mounting plate 5 to drive the buffer tube 2 to move back and forth along the slide rail 4. The driving mechanism 3 is shown in Figure 3 、 Figure 6 , including a motor 31, a crank 32 and a connecting rod 33. The motor 31 is drivingly connected to the crank 32. A vertical chute 335 is opened at the starting end 331 of the connecting rod 33. The crank 32 is clamped into the vertical chute 335 at the starting end 331 of the connecting rod 33, and the starting end 331 of the connecting rod 33 is connected in this way; the ending end 332 of the connecting rod 33 is fixedly connected to the lower mounting plate 5, and the buffer tube 2 is indirectly connected in this way. The motor 31 drives the crank 32 to rotate, and the crank 31 slides vertically along the vertical chute 335 of the connecting rod 33, and drives the mounting plate 5 and the buffer tube 2 to move back and forth along the horizontal slide rail 4 through the connecting rod 33. In the initial state of the buffer tube 2, see Figure 3 , it is at the rearmost side and can only move forward. The notch 10 of the collection tank 1 extends forward and is a strip in the front-rear direction, and the length L3 is 50 mm. If the light source 9 adheres to the front inner wall 255 of the buffer tube 2, then the rear side is in the direction of the discharge port 22, and the front side is against the direction of the discharge port 22. The operator operates the driving mechanism 3 to drive the buffer tube 2 to move forward from the Figure 3 state shown to Figure 7The state shown. During this process, the discharge port 22 of the buffer tube 2 is always aligned with the notch 10 of the collection tank 1. The buffer tube 2 causes the light source 9 to laterally disengage from the front inner wall 255 of the buffer tube 2 backward under the action of inertia and move obliquely downward, leaving the buffer tube 2 from the discharge port 22 and falling into the collection tank 1. If the light source 9 adheres to the rear inner wall 256 of the buffer tube 2, then the front side is the direction towards the discharge port 22, and the rear side is the direction opposite to the discharge port 22. The operator operates the driving mechanism 3 to drive the buffer tube 2 from Figure 7 the state shown and move backward to Figure 3 the state shown. During this process, the discharge port 22 of the buffer tube 2 is always aligned with the notch 10 of the collection tank 1. The buffer tube 2 causes the light source 9 to laterally disengage from the rear inner wall 256 of the buffer tube 2 forward under the action of inertia and move obliquely downward, leaving the buffer tube 2 from the discharge port 22 and falling into the collection tank 1.

[0025] Refer to Figure 3 . In other embodiments, other driving mechanisms such as electric push rods can be used to drive the upper and lower mounting plates 5 to drive the buffer tube 2 to reciprocate back and forth along the slide rail 4.

[0026] In other embodiments, the driving mechanism 3 can be changed to drive the buffer tube 2 to move back and forth until the discharge port 22 of the buffer tube 2 extends forward beyond the front of the notch 10 of the collection tank 1 or the discharge port 22 of the buffer tube 2 extends backward beyond the rear of the notch 10 of the collection tank 1.

[0027] As described above, it is only the implementation mode of the present invention, and the patent protection scope is not limited thereby. Those skilled in the art make non-substantive changes or substitutions based on the present invention, and still fall within the patent protection scope.
