The pump source is disposed within the mounting groove, and a positive electrode plate and a negative electrode plate are fixed on the pump source.

Description

Technical Field

[0001] This invention relates to the field of laser technology, and in particular to a COB-packaged transmit-receive laser and its applications. Background Technology

[0002] Lasers play a crucial role in numerous fields, including optical communication, laser processing, medical equipment, and military applications. When a laser needs to operate continuously, the pump source operates without interruption. As the core energy supply component of the laser, the pump source continuously generates heat during operation. Due to the continuous accumulation of heat, the internal temperature of the pump source rises sharply. Excessive temperature can cause irreversible damage to the internal structure and material properties of the pump source. Current laser designs typically include multiple pump sources, which often operate simultaneously, subjecting each pump source to prolonged high-load operation. This operating mode further exacerbates heat loss from the pump source, significantly shortening its lifespan and consequently affecting the reliability and stability of the entire laser transmission and reception assembly, thus limiting its application in fields with high stability and reliability requirements. Summary of the Invention

[0003] In view of the problems existing in the above-mentioned COB packaged transmitter-receiver laser components and their applications, the present invention is proposed.

[0004] Therefore, the problem to be solved by the present invention is that the pump source in the laser is prone to irreversible heat loss due to continuous operation, and the heat loss is aggravated by the simultaneous high load operation of multiple pump sources, which in turn leads to a shortened service life of the pump source and unstable laser performance.

[0005] To solve the above technical problems, the present invention provides the following technical solution: a COB packaged transmitter-receiver laser, comprising a laser, a laser housing, a cover plate, and a pump source, wherein the cover plate is located on the laser housing, a mounting groove is provided inside the laser housing, the pump source is disposed in the mounting groove, and a positive electrode plate and a negative electrode plate are fixed on the pump source.

The rotating shaft is disposed inside the laser housing, the rotating shaft sleeve is fixed outside the rotating shaft, the rotating ring is fixed on the rotating shaft sleeve, and the insulating block is fixed on the rotating ring.

[0007] An adjustment assembly, located on one side of the rotating shaft, includes a transmission component. The transmission component includes a motor, a rotating shaft, a disc, and a conical block. The motor is fixed to the inner wall of the mounting groove. The rotating shaft is located on one side of the motor. The disc is sleeved on the outside of the rotating shaft. The conical block is fixed on the rotating shaft, and the disc and the conical block are in contact.

[0010] In a preferred embodiment of the COB-packaged laser transmitter-receiver assembly of the present invention, the conductive component further includes an insulating plate and a conductive sheet, wherein the insulating plate is fixed to the inner wall of the mounting groove, and the conductive sheet is fixed on the conductive sheet.

[0014] According to the pin definitions and power requirements of the laser, connect the power cord and control cord correctly, and use the optical path adjustment mechanism of the laser cutting machine to calibrate the optical path of the laser.

[0015] The conductive component conducts the current from the power supply to the pump source, enabling the pump source to operate normally.

[0029] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] Example 1

[0031] Reference Figures 1-11 This is the first embodiment of the present invention. This embodiment provides a COB-packaged transmit-receive component laser and its application. The COB-packaged transmit-receive component laser and its application include a laser 100, a laser housing 101, a cover plate 102, and a pump source 103. The cover plate 102 is located on the laser housing 101. A mounting groove 101-1 is formed inside the laser housing 101. The pump source 103 is disposed in the mounting groove 101-1. A positive electrode plate 103a and a negative electrode plate 103b are fixed on the pump source 103.

[0032] COB packaging is an advanced electronic packaging process, which is existing technology and will not be elaborated on in this solution. Those skilled in the art can clearly understand its working principle. COB packaging has efficient heat dissipation characteristics. The laser housing 101 is an aluminum plate, and the mounting slot 101-1 is also an aluminum plate. The pump source 103 is COB packaged into the mounting slot 101-1, so that the heat generated by the pump source 103 during operation can be dissipated in time through the bottom aluminum plate.

[0033] The cover plate 102 is movably connected to the laser housing 101. When installing the pump source 103, the cover plate 102 can be opened.

[0034] The positive plate 103a is connected to the positive terminal of the power supply, and the negative plate 103b is connected to the negative terminal of the power supply. When both are connected, the pump source 103 can work normally.

[0035] The conductive assembly 200 is disposed on the mounting groove 101-1 and includes a conductive component 201. The conductive component 201 includes a rotating shaft 201a, a rotating shaft sleeve 201b, a rotating ring 201c, and an insulating block 201d. The rotating shaft 201a is disposed inside the laser housing 101, the rotating shaft sleeve 201b is fixed outside the rotating shaft 201a, the rotating ring 201c is fixed on the rotating shaft sleeve 201b, and the insulating block 201d is fixed on the rotating ring 201c.

[0036] When the conductive element 201 is in operation, it conducts electricity to the pump source 103. The rotating shaft 201a is made of insulating material, and both the rotating shaft sleeve 201b and the rotating ring 201c are conductive. When the rotating shaft 201a rotates, it will drive the rotating shaft sleeve 201b to rotate, thereby driving the rotating ring 201c and the insulating block 201d to rotate synchronously. When the positive electrode plate 103a is in contact with the rotating ring 201c, the positive electrode plate 103a is connected to the current, and the pump source 103 can work normally. However, when the positive electrode plate 103a is in contact with the insulating block 201d, the positive electrode plate 103a is not connected to the current, and the pump source 103 will not work.

[0037] The adjustment component 300 is located on one side of the rotating shaft 201a and includes a transmission component 301. The transmission component 301 includes a motor 301a, a rotating shaft 301b, a disc 301c, and a conical block 301d. The motor 301a is fixed to the inner wall of the mounting groove 101-1, the rotating shaft 301b is located on one side of the motor 301a, the disc 301c is sleeved on the outside of the rotating shaft 301b, and the conical block 301d is fixed on the rotating shaft 201a. The disc 301c and the conical block 301d are in contact.

[0038] The transmission component 301 drives the rotating shaft 201a to rotate, which in turn drives the rotating ring 201c to rotate, thereby controlling whether the pump source 103 works. This allows multiple pump sources 103 to work in a rotating mode, so that each pump source 103 can get sufficient rest after working for a period of time, and its internal heat can be effectively dissipated.

[0039] The motor 301a rotates very slowly. There are eight pump sources 103. During the normal operation of the laser 100, one pump source 103 is always in a resting state, while the other seven pump sources 103 are working normally.

[0040] One end of the rotating shaft 301b is movably connected to the motor shaft of the motor 301a. The other end of the rotating shaft 301b is provided with an auxiliary block 301f, which is fixed on the mounting groove 101-1. The other end of the rotating shaft 301b is inserted into the hole on the auxiliary block 301f to provide support for the rotating shaft 301b. When the motor 301a starts, it will drive the rotating shaft 301b to rotate. The rotation of the rotating shaft 301b will drive the disc 301c to rotate. The disc 301c will drive the conical block 301d to rotate, thereby driving the rotating shaft 201a to rotate, and then causing the rotating ring 201c to rotate.

[0041] The adjustment assembly 300 also includes an adjustment component 302, which is disposed on one side of the disc 301c. It includes a moving column 302a, a fixed block 302b, a push rod 302c, a rubber block 302d, and a piston cylinder 302e. A sliding groove 301b-1 is provided on the rotating shaft 301b. The moving column 302a slides in the sliding groove 301b-1. The fixed block 302b is fixed to one end of the moving column 302a. The push rod 302c is disposed on one side of the fixed block 302b. The rubber block 302d is fixed to one side of the push rod 302c. The piston cylinder 302e is fixed on the mounting groove 101-1.

[0042] The adjustment component 302 is designed to increase the rotation speed of the rotating shaft 301b when the temperature inside the laser 100 rises, thereby shortening the cycle of pump source 103's rest period, allowing it to rest more frequently, accelerating heat dissipation, and timely reducing the temperature of pump source 103, thus effectively addressing the impact of high-temperature environment on the lifespan of pump source 103.

[0043] The movable column 302a is fixed to the inner side of the disk 301c. When the motor 301a drives the rotating shaft 301b to rotate, it will drive the movable column 302a to rotate, thereby driving the disk 301c to rotate, and will not hinder the disk 301c from moving along the rotating shaft 301b.

[0044] Initially, the disk 301c is located at the position with the largest radius of the cone block 301d. As the temperature inside the laser 100 increases, the rubber block 302d will move towards the disk 301c. The rubber block 302d will push the push rod 302c to move, which will drive the fixed block 302b to move, causing the moving column 302a to slide in the slide groove 301b-1. This will cause the disk 301c to move along the outer surface of the cone block 301d to a position with a smaller radius. Since the speed of the motor 301a remains constant, the speed of the rotating shaft 301b remains constant. However, at this time, the radius of the cone block 301d in contact with the disk 301c is smaller. When the rotating shaft 301b rotates by the same angle, the angle of rotation of the cone block 301d will become larger, thereby accelerating the rotation speed of the rotating shaft 201a. This will shorten the cycle of the pump source 103's rest, allowing it to rest more frequently and accelerating the heat dissipation.

[0045] Example 2

[0046] Reference Figures 1-11 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0047] Specifically, the piston cylinder 302e has a chamber 302e-1, and the rubber block 302d slides within the chamber 302e-1.

[0048] A through hole is provided at one end of the piston cylinder 302e, into which the push rod 302c is inserted. The rubber block 302d is tightly fitted to the inner wall of the piston cylinder 302e. Air is provided between the side of the rubber block 302d away from the push rod 302c and the piston cylinder 302e. The air cannot move to the other side of the rubber block 302d. The rubber block 302d and the inner wall of the piston cylinder 302e have good sealing performance. Due to the thermal expansion and contraction properties of air, when the temperature inside the laser 100 rises, the volume of air between the side of the rubber block 302d away from the push rod 302c and the piston cylinder 302e will expand, thereby pushing the rubber block 302d to move closer to the disk 301c.

[0049] One end of the fixed block 302b is rotatably connected to the push rod 302c. The fixed block 302b has a rotating groove 302b-1. A rotating block 302f rotates in the rotating groove 302b-1. One end of the rotating block 302f is fixed to the push rod 302c. This ensures that when the motor 301a drives the disc 301c, the moving column 302a and the fixed block 302b to rotate, the rotating block 302f moves in the rotating groove 302b-1 and does not affect the movement of the push rod 302c.

[0050] Specifically, the conductive component 201 also includes an insulating plate 201e and a conductive sheet 201f. The insulating plate 201e is fixed to the inner wall of the mounting groove 101-1, and the conductive sheet 201f is fixed on the conductive sheet 201f.

[0051] Specifically, a first movable groove 103a-1 is formed on the positive electrode plate 103a, and a first gasket 103c is provided in the first movable groove 103a-1. The first gasket 103c is in contact with the rotating ring 201c. A second movable groove 103b-1 is formed on the negative electrode plate 103b, and a second gasket 103d is provided in the second movable groove 103b-1. The second gasket 103d is in contact with the conductive sheet 201f.

[0052] The first gasket 103c has a first spring 103e fixed at one end and a first moving groove 103a-1 fixed at the other end, which is used to ensure that the first gasket 103c fits against the rotating ring 201c. The second gasket 103d has a second spring 103f fixed at one end and a second moving groove 103b-1 fixed at the other end, which is used to ensure that the second gasket 103d fits tightly against the conductive sheet 201f.

[0053] Specifically, an annular groove 201b-1 is provided inside the rotating sleeve 201b, and a rotating block 201g is provided inside the annular groove 201b-1. A first wire 201h is provided at one end of the rotating block 201g.

[0054] A wiring mechanism 104 is fixed on the laser housing 101. The wiring mechanism 104 can be connected to an external power source to provide a stable power supply to the laser 100.

[0055] A conductive plate 201l is fixed on one side of the rotating block 201g. One end of the first wire 201h is connected to the conductive plate 201l. Both the rotating block 201g and the conductive plate 201l are conductive. The other end of the first wire 201h is connected to the positive terminal of the power supply of the wiring mechanism 104. Through the conduction of the conductive plate 201l, the rotating block 201g and the rotating ring 201c, the positive plate 103a is connected to the positive terminal of the power supply.

[0056] The rotating block 201g is designed so that when the rotating sleeve 201b rotates, the rotating block 201g can slide within the annular groove 201b-1, without pulling on the first wire 201h, thus ensuring the stability of the connection of the first wire 201h.

[0057] Specifically, an auxiliary plate 201i is fixed on one side of the insulating plate 201e, and a second conductor 201j is provided on one side of the auxiliary plate 201i.

[0058] The auxiliary plate 201i is made of insulating material. The second wire 201j passes through the auxiliary plate 201i and is connected to the conductive sheet 201f. The other end of the second wire 201j is connected to the negative terminal of the power supply of the wiring mechanism 104. The negative plate 103b is connected to the negative terminal of the power supply through the conductive sheet 201f.

[0059] Example 3

[0060] Reference Figures 1-11 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0061] Specifically, there are multiple rotating rings 201c and corresponding insulating blocks 201d.

[0062] Two positive plates 103a of pump sources 103 are set on a rotating ring 201c. There are four sets of rotating rings 201c and insulating blocks 201d. The angle of the insulating block 201d is 45 degrees. The relative positions of the four sets of rotating rings 201c and insulating blocks 201d are different, ensuring that when the rotating sleeve 201b rotates a full circle, there is always one positive plate 103a of pump source 103 in contact with the insulating block 201d. The positive plate 103a cannot be energized, and the pump source 103 will not work at this time. The positive plates 103a of the other seven pump sources 103 are all located on the rotating ring 201c and can work normally.

[0063] Specifically, the rotating shaft 201a is provided with a support plate 201k, which is connected to the bearing of the rotating shaft 201a.

[0064] The support plate 201k provides stable support for the rotating shaft 201a.

[0065] Specifically, a rubber ring 301e is fixed to the outside of the disc 301c, and the rubber ring 301e is in contact with the outer surface of the cone block 301d.

[0066] By setting the rubber ring 301e, the friction between the disc 301c and the cone block 301d is increased, so that the rotation of the disc 301c can smoothly drive the rotation of the cone block 301d.

[0067] The rotating shaft 301b is parallel to the generatrix of the conical block 301d, ensuring that the rubber ring 301e is always in contact with the outer surface of the conical block 301d when the disk 301c moves along the rotating shaft 301b.

[0068] Specifically, according to the design requirements of the laser cutting machine, the COB packaged laser assembly is accurately installed in the designated position and secured firmly with screws or clamps to ensure that it does not shift or shake during the cutting process.

[0069] According to the pin definitions and power requirements of laser 100, connect the power cord and control cord correctly, and use the optical path adjustment mechanism of the laser cutting machine to calibrate the optical path of laser 100.

[0070] The conductive component 200 conducts the current from the power supply to the pump source 103, enabling the pump source 103 to operate normally. The regulating component 300 enables multiple pump sources 103 to operate in a rotating mode, thereby facilitating heat dissipation of the pump sources 103 and improving the service life of the laser 100.

[0071] When using the pump source 103, after installation, ensure that the first gasket 103c is in contact with the rotating ring 201c, the second gasket 103d is in close contact with the conductive sheet 201f, the positive plate 103a is connected to the positive terminal of the power supply, and the negative plate 103b is connected to the negative terminal of the power supply.

[0072] The motor 301a is started, which drives the rotating shaft 301b to rotate. The rotation of the rotating shaft 301b drives the disk 301c to rotate, which in turn drives the conical block 301d to rotate, thereby driving the rotating shaft 201a to rotate, which in turn causes the rotating ring 201c to rotate. When the rotating shaft 201a rotates, it drives the rotating shaft sleeve 201b to rotate, thereby causing the rotating ring 201c and the insulating block 201d to rotate synchronously. When the positive electrode plate 103a is in contact with the rotating ring 201c, the positive electrode plate 103a... When the current is turned on 3a, the pump source 103 can work normally. However, when the positive electrode plate 103a is in contact with the insulating block 201d, the positive electrode plate 103a is not turned on, and the pump source 103 will not work. During the normal operation of the laser 100, one pump source 103 is always in a resting state, that is, the other seven pump sources 103 work normally. As the motor 301a rotates, the pump sources 103 take turns resting, so that the heat inside the pump source 103 can be effectively dissipated.

[0073] Initially, the disk 301c is located at the position with the largest radius of the cone block 301d. As the temperature inside the laser 100 increases, the air volume between the side of the rubber block 302d away from the push rod 302c and the piston cylinder 302e will expand, thereby pushing the rubber block 302d to move closer to the disk 301c. The rubber block 302d will push the push rod 302c to move, driving the fixed block 302b to move, causing the moving column 302a to slide in the slide groove 301b-1, thereby moving the disk 301c along the outer surface of the cone block 301d to a position with a smaller radius of the cone block 301d, thereby accelerating the rotation speed of the rotating shaft 201a, and thus shortening the cycle of the pump source 103, allowing it to rest more frequently and accelerating the heat dissipation rate.

[0074] At the same time, when the motor 301a drives the disc 301c, the moving column 302a and the fixed block 302b to rotate, the rotating block 302f moves in the rotating groove 302b-1, which will not affect the movement of the push rod 302c.

[0075] When the temperature inside the laser 100 drops, the side of the rubber block 302d away from the push rod 302c and the air volume in the piston cylinder 302e decrease, causing the rubber block 302d to move away from the disk 301c back to its initial position, and the cycle of the pump source 103 will also return to its initial state.

[0076] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
