Description

Technical Field

[0001] The invention belongs to the technical field of diamond wire saws, and in particular relates to a diamond bead high-speed counter. Background Art

[0002] Diamond wire saws are widely used as tools for cutting materials such as stone and concrete. They are mainly composed of steel wire ropes, beads set on the steel wire ropes at intervals, and other components; the beads are composed of a steel matrix, diamonds fixed on the steel matrix, and bonding powder. Diamond wire saws are high-value products, and beads are the core parts of diamond wire saws and are high-value parts. In the process of diamond wire saws, when the process is handed over, such as the entry and exit of semi-finished beads in the transit warehouse, the entry and exit of finished beads in the warehouse, etc., the number of beads must be determined. At present, the main methods for counting beads are:

[0003] ① Manual counting method: This method is inefficient. For example, if 500,000 beads are counted in one day, about 5 people are needed. The labor cost is high and it is very easy to make mistakes.

[0004] ② Weighing and counting method: Weigh the weight of a batch of beads and divide it by the expected value of the weight of a single bead to estimate the number of beads in the batch. This method is not prone to major errors, but the accuracy rate is low.

[0005] ③ Template counting method: put the beads into the counting template, and then circulate the counting template with beads. This method is relatively accurate, but it takes a lot of manpower to put the beads into the counting template, and the circulation of beads is also very inconvenient.

[0006] As can be seen from the above, it is difficult for the existing technology to accurately and efficiently achieve bead counting, there is a risk of high-value beads being stolen, and it is inconvenient to manage the diamond wire saw preparation process. Summary of the invention

[0007] In view of this, in order to solve the problems raised in the above background technology, the purpose of the present invention is to provide a diamond bead high-speed counter. The beads are used to make free fall motion vertically downward. After a period of time, two adjacent beads have a larger falling speed, so that a larger gap is formed between the two adjacent beads in a very short time (several milliseconds), which is convenient for the light sensor to count, thereby greatly improving the bead counting speed and accuracy.

[0008] To achieve the above object, the present invention provides the following technical solutions:

[0009] A diamond bead high-speed counter comprises diamond beads to be counted, a conduit through which the diamond beads can pass, and a light flux sensor matched to the outside of the conduit;

[0010] The upper part of the conduit is a 1 / 4 arc circular tube, the lower part of the conduit is a straight circular tube, and two light-transmitting slots are symmetrically provided on the straight circular tube;

[0011] The optical flux sensor comprises an emitting part and a receiving part symmetrically located on two sides of the straight circular tube, and the light emitted by the emitting part can pass through two light passing slots and be received by the receiving part.

[0012] Preferably, the radius of the arc tube is 10 to 150 mm.

[0013] Preferably, the top of the conduit is connected to an inclined guide rail, and the diamond beads are introduced into the conduit along the guide rail.

[0014] Preferably, the inclination angle α of the guide rail to the horizontal direction is less than 10°.

[0015] Preferably, an anti-slip strip is fixed inside the guide rail.

[0016] Preferably, the diamond bead high-speed counter also includes a vibrating screener capable of automatically loading the diamond beads onto the guide rail, and the guide rail is fixedly connected to the outer barrel of the vibrating screener.

[0017] Preferably, the light flux sensor includes a first sensor and a second sensor which are arranged in sequence from top to bottom.

[0018] Preferably, the diamond bead high-speed counter further comprises a material box located below the straight circular tube, and the material box is used to receive the diamond beads passing through the conduit.

[0019] Preferably, the diamond bead high-speed counter also includes a base for supporting the vibrating screener and the material box, and a conduit support for supporting the conduit, a first support for supporting the first sensor, and a second support for supporting the second sensor are fixed to one side of the base.

[0020] Preferably, a control box is also fixed on the base, and a main controller, a data storage device, a wireless transmitter and a liquid crystal display are arranged in the control box, and the light flux sensor is communicatively connected with the main controller via the wireless transmitter.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] The high-speed counter of the present invention utilizes the free fall of an object to create a gap of 9 to 54 mm between two adjacent beads in milliseconds, creating favorable conditions for the optical flux sensor to accurately count, making the counting efficiency high and accurate, and achieving precise management of the handover in the preparation process of diamond beads. Specifically, the counting device of the present invention is suitable for counting small cylindrical or spherical parts such as diamond beads and diamond bead substrates.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] like Figure 1 As shown, a diamond bead high-speed counter includes a base 1, a control box 2, a vibrating screener 3, a guide rail 4, an anti-slip strip 5, diamond beads 6, a conduit 7, a conduit support 8, a first support 9, a first sensor 10, a second sensor 11, a second support 12 and a material box 13.

[0030] The control box 2 and the vibrating screen 3 are both fixed to the base 1 by bolts; Figure 4 As shown, the control box 2 is provided with electrical components such as a main controller, a data storage device, a wireless transmitter and a liquid crystal display screen, and the light flux sensor is communicatively connected with the main controller via the wireless transmitter.

[0031] The guide rail 4 is fixedly connected to the outer barrel of the vibration screener 3, and the inclination angle α of the guide rail 4 to the horizontal direction is less than 10°, and the anti-slip strip 5 is fixed inside the guide rail 4. The diamond beads 6 are arranged in the guide rail 4 through the vibration screening of the vibration screener 3, and form a uniform upward movement in the guide rail 4; the anti-slip strip 5 is made of diamond and metal powder mixed and sintered at high temperature, or electroplated with diamond on a metal matrix, or made of cemented carbide with teeth, so as to prevent the diamond beads 6 from slipping in the guide rail 4, thereby ensuring the uniform transportation of the diamond beads 6.

[0032] The conduit 7 is fixed to one side of the base 1 through a conduit support 8, and the upper part of the conduit 7 is a 1 / 4 arc circular tube, and the lower part of the conduit 7 is a straight circular tube. Figure 2 As shown: the radius of the arc tube is preferably 10-150 mm, and two light-through grooves are symmetrically provided on the straight tube (the inner diameter of the conduit 7 is 1-3 mm larger than the outer diameter of the diamond beads, and the inner wall finish of the arc tube is less than 0.016 mm).

[0033] The first sensor 10 is fixed to one side of the base 1 through the first support 9, and the second sensor 11 is fixed to one side of the base 1 through the second support 12, and the first sensor 10 is located above the second sensor 11. Both the first sensor 10 and the second sensor 11 are U-shaped structures, and the U-shaped structure includes a transmitter and a receiver symmetrically located on both sides of the straight circular tube, and the light emitted by the transmitter can pass through two light-through slots and be received by the receiver. Specifically, the distance S between the position of the first sensor 10 and the center of the top of the catheter 7 is 0.5m~1.8m, the time Tclosed for the sensor light to scan across the beads is 0.002~0.005s, the gap L between two adjacent beads is 9~54mm, the time Topen for the sensor light to scan across the gap between two adjacent beads is 0.003~0.009s, the time T1 for counting a diamond bead is 0.005~0.014s, or 70~200 diamond beads are counted per second (the smaller the number of diamond beads counted per second, the smoother the diamond beads pass through the arc tube and the more accurate the counting. In actual production, counting about 50 diamond beads per second can meet the requirements).

[0034] The material box 13 is supported and placed on the base 1 and is used to receive the diamond beads 6 passing through the conduit 7 .

[0035] In summary, when counting the diamond beads 6:

[0036] (1) Pour the diamond beads 6 to be counted into the outer barrel of the vibrating screen 3, and control the upward speed of the diamond beads 6 along the guide rail 4 by adjusting the vibration frequency of the vibrating screen 3;

[0037] (2) The diamond beads 6 are free-falling through the conduit 7. Figure 3 As shown, bead E starts from the initial position (at this time, the falling speed of bead E is zero) and moves downward in free fall. As shown in Figure A; the distance to the light flux sensor position (light switch position) is S (in meters) and the time is T S (unit is s); as shown in Figure B; the distance that the light from the light flux sensor sweeps across the bead E is a (unit is mm), at which time the light is blocked by the bead E, and the light blocking time is T 闭(unit is s); as shown in Figure C: L (unit is mm) is the distance between the gap between two adjacent beads E and F when the light from the light flux sensor passes through. At this time, the light is unobstructed, and the unobstructed time is T 通 (Unit: s); As shown in Figure C and Figure D: T can be controlled by adjusting the frequency of the vibrator in the vibration plate; T 1 =T 闭 +T 通 It is the time to count a bead (in seconds).

[0038] S=g*T S 2 / 2;

[0039] S+a=g*(T S +T 闭 ) 2 / 2;

[0040] T S -L=T S -T 通 ;

[0041] L=S-g*(T S-L ) 2 / 2;

[0042] In the above formula: g is the acceleration due to gravity, g = 10m / s 2 ; T S-L is the time taken for bead 2 to freely fall from its initial position to a certain distance (S-L), in s; a is the length of the bead base. To simplify the calculation, a=14mm is taken.

[0043] Based on the above formula, we can calculate: the time it takes to count a bead T 1 The relationship between the distance L between the gap between two adjacent beads E and F and the distance S between the beads falling freely downward to the position of the optical switch is shown in Table 1.

[0047] (3) If the number of beads sensed by the two first sensors 10 and the second sensor 11 differ by 0.1%, the number of the counter is valid and the maximum value is taken as the number of diamond beads;
