Description

Technical Field

[0001] The present invention belongs to the field of lamp bead wire bonding, and particularly relates to a protective type automatic wire bonding device for LED lamp beads. Background Art

[0002] LED lamp bead wire bonding refers to a process of electrically connecting an LED lamp bead to a circuit board. This process generally includes soldering the pins of the lamp bead to a PCB (printed circuit board) to ensure the normal operation of the LED. The soldering methods are generally manual soldering and automatic soldering. In the production process of LED lamp beads, the application of automatic wire bonding devices is very extensive;

[0003] Traditional automatic wire bonding devices for LED lamp beads have many defects; on the one hand, they lack effective protection structures. In an environment such as a production workshop where there is frequent movement of personnel and equipment, the external structure or personnel can easily accidentally touch the working soldering head. This not only may cause damage to the soldering head, increase the equipment maintenance cost and downtime, and affect production efficiency, but also may lead to problems such as poor welding contact, false soldering, and deformation of solder joints, seriously affecting the welding quality and yield rate of LED lamp beads; on the other hand, if a person accidentally touches the high-temperature soldering head, it is very likely to cause a scalding accident, threatening the personal safety of the staff; moreover, even if the traditional device has simple protection, when it is impacted, the protection structure cannot effectively buffer the impact force. When the direction of the impact force is irregular, the buffer components are easily bent and damaged due to uneven force, resulting in the failure of the buffer function. Summary of the Invention

[0024] To make the above objects, features and advantages of the present invention more obvious and understandable, the following will make a detailed description of the specific embodiments of the present invention in conjunction with the drawings of the specification.

[0025] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0026] Second, the so-called "one embodiment" or "embodiment" herein refers to specific features, structures, or characteristics that may be included in at least one implementation manner of the present invention. The appearances of "in one embodiment" in different places in this specification do not all refer to the same embodiment, nor are they separate or selectively exclusive embodiments from other embodiments.

[0027] As shown in the appended Figure 1 , 2 and the appended Figure 3 as follows:

[0028] Embodiment 1: This embodiment provides a protective automatic wire welding device for LED lamp beads, including a main body 1 and a protection mechanism 2; the main body 1 includes a base 101, a fixing seat 105 is arranged on the top of the base 101, brackets 102 are arranged on the top of the base 101 on both sides of the fixing seat 105, a linear driving member 103 is arranged between the brackets 102, and a welding head 104 is arranged at the output end of the linear driving member 103; the protection mechanism 2 includes a protective shell 201 located outside the fixing seat 105, a collar 207 is arranged outside the welding head 104, and a movable ring 205 is movably arranged outside the collar 207 through a buffer member, and the movable ring 205 is connected to the protective shell 201; the buffer member includes a movable seat one 2071 arranged on the top of the collar 207, a movable seat two 2072 is movably arranged on the top of the movable ring 205, a limiting rod 2073 is arranged on the movable seat one 2071, the limiting rod 2073 penetrates through the movable seat two 2072, and a first spring 2074 is arranged between the movable seat one 2071 and the movable seat two 2072.

[0029] During operation, the circuit board with LED lamp beads is fixed on the fixing seat 105. After inputting the image position parameters into the controller located on the bracket 102, the controller will send control commands to the linear driving member 103 and the welding head 104 through wires for operation. The linear driving member 103 can adopt an electric rod, a hydraulic rod, or a screw linear driver to drive the welding head 104 to descend and weld the LED lamp bead pins on the circuit board. The specific welding method adopts the traditional soldering method, and no redundant description will be given here;

[0030] The protective shell 201 will shield and protect the welding head 104 and the LED lamp beads at the welding position during the welding operation, avoiding problems such as damage to the welding head 104, poor welding contact, false soldering, solder joint deformation, and even scalding of the staff caused by external structures or accidental contact and collision of personnel;

[0031] When the external structure or personnel collide with the protective shell 201, the protective shell 201 will move in the opposite direction of the personnel due to the impact force. During the movement, the movable ring 205 will be driven to move synchronously. However, the collar 207 will not move under the limitation of the welding head 104. The first spring 2074 close to the personnel will contract because the distance between the collar 207 and the movable ring 205 is reduced. The first spring 2074 far from the personnel will expand synchronously. Then, the elasticity of the first spring 2074 is used to absorb and buffer the impact force. After the impact force disappears, the protective shell 201 will be driven back to the initial position to continue the protection work, improving the protection effect. When the direction of the impact force is between two adjacent buffer members and does not align with the buffer member, the orientation of the limiting rod 2073 is inclined compared with the direction of the impact force. When the movable ring 205 continues to move under the impact force, the first movable seat 2071 and the second movable seat 2072 swing between the movable ring 205 and the collar 207. During the process, due to the reduction or increase of the distance between the first movable seat 2071 and the second movable seat 2072, the first spring 2074 contracts or expands synchronously for buffering operations. Under the limiting and guiding of the limiting rod 2073, the first spring 2074 always maintains a vertical and horizontal state, avoiding the bending of the first spring 2074 during the buffering operation due to the impact force direction not being perpendicular to the first spring 2074, which may lead to the weakening of its elastic characteristics, reduction of the buffering effect, or even material fatigue damage due to uneven stress, extending the service life of the device, and providing multi-directional buffer protection around the welding head 104;

[0032] A micro damper can be set between the first movable seat 2071 and the second movable seat 2072 to reduce the rebound phenomenon after buffering and improve the buffering effect.

[0033] As shown in the Figure 3 appendix:

[0034] Specifically, multiple groups of buffer members are provided, and the multiple groups of buffer members are respectively located outside the collar 207.

[0035] While improving the buffer protection effect, multi-directional buffer protection can be provided around the welding head 104.

[0036] Specifically, baffles 202 are rotatably provided at both ends of the protective shell 201.

[0037] The staff can place or remove the circuit board by rotating and opening the baffle 202.

[0038] As shown in the Figure 4 appendix:

[0039] Embodiment 2: This embodiment provides a protective automatic wire welding device for LED lamp beads, including a main body 1 and a protection mechanism 2; the main body 1 includes a base 101, a fixing seat 105 is arranged on the top of the base 101, brackets 102 are arranged on the top of the base 101 on both sides of the fixing seat 105, a linear driving member 103 is arranged between the brackets 102, and a welding head 104 is arranged at the output end of the linear driving member 103; the protection mechanism 2 includes a protective shell 201 located outside the fixing seat 105, a collar 207 is arranged outside the welding head 104, a movable ring 205 is movably arranged outside the collar 207 through a buffer member, and the movable ring 205 is connected to the protective shell 201; the buffer member includes a movable seat one 2071 arranged on the top of the collar 207, a movable seat two 2072 is movably arranged on the top of the movable ring 205, a limiting rod 2073 is arranged on the movable seat one 2071, the limiting rod 2073 penetrates through the movable seat two 2072, and a first spring 2074 is arranged between the movable seat one 2071 and the movable seat two 2072.

[0040] As shown in the attached Figure 3 figure:

[0041] Specifically, multiple groups of buffer members are provided, and the multiple groups of buffer members are respectively located outside the collar 207.

[0042] As shown in the attached Figure 1 and the attached Figure 2 figure:

[0043] Specifically, a movable groove 204 is arranged on the top surface of the protective shell 201, the movable ring 205 is slidably connected to the movable groove 204, and inclined seats 203 are arranged on the top of the base 101 on both sides of the fixing seat 105.

[0044] Specifically, an electric guide rail one 106 is arranged between the top of the base 101 and the fixing seat 105, and an electric guide rail two 107 is arranged between the bracket 102 and the linear driving member 103.

[0045] Specifically, sliding grooves 206 are arranged on both side surfaces of the movable ring 205, and the sliding grooves 206 are slidably connected to the protective shell 201.

[0046] Specifically, baffles 202 are rotatably arranged at both ends of the protective shell 201.

[0047] As shown in the attached Figure 4 figure:

[0048] Specifically, the collar 207 is movably sleeved on the welding head 104, and an airbag 208 is arranged on the outer surface of the welding head 104.

[0049] The movable ring 205 is limited on the protective housing 201 through the sliding groove 206, so that it will not be completely separated from the protective housing 201. The position of the collar 207 is supported by the buffer member, so that the collar 207 drops without being directly connected to the welding head 104. The collar 207 is movably sleeved on the welding head 104. When the linear driving member 103 drives the welding head 104 to move up and down for wire welding operations on multiple LED lamp beads, it will not drive the collar 207, the movable ring 205 and the protective housing 201 to move together. When the protective housing 201 is impacted, the impact force will be transmitted to the collar 207 through the buffer member. After buffering, the excess impact force will push the collar 207 to continue moving, thereby squeezing the airbag 208, so as to use the elasticity of the airbag 208 for further buffer protection and avoid directly acting on the welding head 104 and causing damage.

[0051] As shown in the attached Figure 3 figure:

[0052] Specifically, multiple groups of buffer members are provided, and the multiple groups of buffer members are respectively located outside the collar 207.

[0053] As shown in the attached Figure 1 and the attached Figure 2 figure:

[0054] Specifically, a movable groove 204 is arranged on the top surface of the protective housing 201, the movable ring 205 is slidably connected to the movable groove 204, and inclined seats 203 are arranged on the top of the base 101 on both sides of the fixing seat 105.

[0055] Specifically, an electric guide rail one 106 is arranged between the top of the base 101 and the fixing seat 105, and an electric guide rail two 107 is arranged between the bracket 102 and the linear driving member 103.

[0056] Specifically, sliding grooves 206 are provided on both side surfaces of the movable ring 205, and the sliding grooves 206 are slidably connected to the protective shell 201.

[0057] Specifically, baffles 202 are rotatably provided at both ends of the protective shell 201.

[0058] The staff can place or remove the circuit board by rotating and opening the baffle 202.

[0059] As shown in the Figure 4 appendix:

[0060] Specifically, the collar 207 is movably sleeved on the welding head 104, and an airbag 208 is provided on the outer surface of the welding head 104.

[0061] As shown in the Figure 4 appendix and the Figure 5 appendix:

[0062] Specifically, the automatic wire welding device further includes a detachment mechanism 3. The detachment mechanism 3 includes a connection seat 301 provided on the welding head 104. A push rod 307 is provided at the output end of the linear drive member 103. The front end of the push rod 307 penetrates through the connection seat 301. A second spring 302 is provided between the connection seat 301 and the push rod 307. A card slot 308 is provided on the push rod 307. A clamping seat 309 is movably provided in the connection seat 301. The clamping seat 309 is adapted to the card slot 308. An air cylinder 305 is provided in the connection seat 301 at the front end of the clamping seat 309. A piston rod 306 is movably provided in the air cylinder 305. A connecting pipe 304 is provided between the air inlet end of the air cylinder 305 and the air outlet end of the airbag 208.

[0063] Specifically, the piston rod 306 penetrates through the air cylinder 305 and contacts the clamping seat 309. The rear end of the clamping seat 309 penetrates through the connection seat 301. A protective frame 303 is provided at the bottom of the linear drive member 103 around the push rod 307.

[0064] When the airbag 208 is squeezed, the gas inside it will be squeezed into the air cylinder 305 through the connecting pipe 304. Then, under the action of air pressure, the piston rod 306 is pushed to move. Since the clamping seat 309 is in the moving direction of the piston rod 306, the clamping seat 309 will be pushed to move together during the movement of the piston rod 306, so that the clamping seat 309 is separated from the card slot 308, and the fixed connection relationship between the welding head 104 and the push rod 307 is released. At this time, the elastic potential energy accumulated by the second spring 302 will push the welding head 104 upward, so that the welding head 104 is separated from the circuit board and the LED lamp beads, avoiding the situation of poor welding contact, virtual soldering, solder joint deformation, and even structural damage resulting in waste caused by the welding head 104 still contacting the circuit board and the lamp beads under the action of external force;

[0065] When the impact source release device needs to be reset, only need to control the linear drive member 103 to pull the push rod 307 together with the welding head 104 to move upward. When the connecting seat 301 contacts the contact protection frame 303, it will be blocked and stop moving. However, since the push rod 307 is not fixedly connected to the welding head 104, it can continue to move upward, thereby compressing the second spring 302 and accumulating elastic potential energy until the clamping seat 309 is aligned with the clamping groove 308. At this time, stop the linear drive member 103 and push the clamping seat 309 back to its original position to engage it with the clamping groove 308, then the connection relationship between the push rod 307 and the welding head 104 can be restored to continue the wire welding operation.
