DETAILED DESCRIPTION

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are 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 making creative efforts shall fall within the scope of protection of the present invention.

[0026] Existing selective wave soldering machines generate a large amount of welding slag during maintenance and welding operations. The falling and splashing of welding slag can easily cause fires, personal injuries and other accidents. Since the falling welding slag has an uncertain landing point during the welding process, it poses a safety hazard to the engineering operation. In particular, the welding slag carries high temperature and heat, which can easily cause fires when it encounters combustible materials. Therefore, it is necessary to provide a device that can be used to collect the welding slag dropped by the selective wave soldering machine.

[0027] Since the selective wave soldering machine uses a mechanical device to move the nozzle along the x and y directions of the equipment when it is working, and during maintenance, the mechanical device needs to be returned to the mechanical origin (the side of the equipment) for inspection and maintenance, it is necessary to provide a device for placing equipment maintenance tools;

[0028] In the actual working process, the selective wave soldering machine will spray flux on the PCB. During its maintenance and inspection, it is necessary not only to perform various operations on the nozzle and the inside of the tin pot, but also to inevitably have tin slag falling and need to be caught. Moreover, when the staff takes out the mechanical accessories in the tin pot, such as the nitrogen ring, tin tube and other parts, due to the high temperature inside the tin pot, the parts in the tin pot may not have cooled to room temperature. Therefore, it is necessary to provide a tool that can receive the tin slag and place the accessories in the tin pot.

[0029] At present, there is a welding slag receiver with a cooling function in the prior art, including a slag receiving pan and a slag receiving bucket, a slag receiving port is provided in the middle position of the slag receiving pan, the slag receiving bucket is located in the middle position of the bottom of the slag receiving pan, the upper end of the slag receiving bucket is connected with the slag receiving port, and the connection between the slag receiving bucket and the slag receiving port is a slope, and clean water is provided at the bottom of the slag receiving bucket 71, and hanging buckles are provided at the four corners of the top of the slag receiving pan, and the hanging buckles on one side are movably connected to the first hanging rod, and the hanging buckles on the other side are movably connected to the second hanging rod; the present invention can be hung to the welding position through the first hanging rod and the second hanging rod, and the slag receiving tool in the shape of a conical funnel is formed by the slag receiving pan and the slag receiving bucket, which can cover the range of welding slag splashing, so that the welding slag falls into the slag receiving bucket, thereby effectively controlling the welding slag splashing, and the clean water inside the slag receiving bucket can quickly extinguish the fallen welding slag to avoid fire hazards.

[0030] Although the above-mentioned welding slag receiver with cooling function has a certain cooling function, since the above-mentioned cooling device cannot be moved and is mainly cooled by the clean water inside the slag hopper, its cooling effect is poor. Therefore, it is necessary to make improvements.

[0031] In response to the above problems, Figure 1 As shown, an embodiment of the present invention provides a slag collecting device for a selective wave soldering machine, which can integrate functions such as equipment maintenance, temporary storage of accessories in the solder pot, and collection of solder slag, thereby improving the convenience and safety of the selective wave soldering machine. Specifically, the slag collecting device for a selective wave soldering machine includes:

[0032] Multiple discharge trays, each of which is provided with an open slot 1 for slag dropped from the wave soldering machine, and two adjacent discharge trays are connected by a detachable connecting seat 2, each of which is provided with a handle 31 mounted on the outer wall of the discharge tray and a roller 32 mounted on the bottom of the discharge tray;

[0033] The plurality of discharge trays include a tool tray 4 for placing equipment maintenance tools, a first receiving tray 51 for receiving waste dropped by the sprayed flux, and a container tray 6 for placing accessories in the tin pot;

[0034] The bottom of the tool tray 4 is connected to a plurality of tool partitions 46 extending to the side walls of the tool tray 4, and a tool hook 45 installed on the side walls of the tool tray 4; a chamfer is provided between the side wall of the first receiving tray 51 and the bottom of the first receiving tray 51; the container tray 6 is sequentially paved with shock-absorbing pads and anti-slip pads from bottom to top.

[0035] In the above technical solution, the first receiving tray 51 and the second receiving tray 52 can both be called receiving trays, and the detachable connecting seat 2 allows the tool tray 4, the first receiving tray 51 and the container tray 6 to be separated or combined as needed, thereby making the use of the present invention more convenient, thereby improving the convenience of use of the selective wave soldering machine; at the same time, under the joint action of the tool tray 4, the receiving tray and the container tray 6, the present invention realizes the integration of functions such as equipment maintenance, temporary storage of accessories in the tin pot and collection of welding slag; the tool partition 46 can partition the tool tray 4 to avoid different tools being mixed together, thereby facilitating the staff to find maintenance tools.

[0036] During actual work, the tool hook 45 can be used to hang maintenance tools, and the chamfering allows workers to more conveniently remove welding slag (such as tin slag) on ​​the inner wall of the first receiving tray 51; the shock-absorbing pad and the anti-slip pad can provide certain protection for the accessories in the tin pot on the container tray 6 to prevent damage to the accessories in the tin pot.

[0037] During actual work, the above-mentioned chamfer is preferably a rounded corner, so that the staff can more conveniently remove the welding slag on the inner wall of the first receiving tray 51; further, the diameter R of the above-mentioned rounded corner is 1 / 4 to 1 / 2 times the width of the first receiving tray 51. For example, when the width of the first receiving tray 51 is 40 cm, the diameter R of the above-mentioned rounded corner is 10 to 20 cm.

[0038] In actual work, the shock-absorbing pad can be made of a high-temperature resistant shock-absorbing rubber gasket with certain fire resistance, and the anti-slip pad can be made of a steel sheet metal. The interface of the anti-slip pad is a wavy structure, and the surface of the anti-slip pad can be provided with anti-slip textures. In this way, the present invention can also realize the function of absorbing tin slag and placing accessories in the tin pot.

[0039] The detachable connector 2 includes a first earring 21 mounted on the outer wall of one of the discharge trays, a second earring 22 mounted on the outer wall of the other discharge tray, and a stopper plug 23 that connects the first earring 21 and the second earring 22. Thus, when two adjacent discharge trays need to be combined, the first earring 21 and the second earring 22 can be connected together using the stopper plug 23. When the two adjacent discharge trays need to be separated, the stopper plug 23 is removed from the first and second earrings 21, 22 and replaced with the first or second earring 21, 22. Thus, the present invention achieves the purpose of separating two adjacent discharge trays.

[0040] During actual operation, there are holes in the first earring 21 and the second earring 22, and the first earring 21 is located below the second earring 22. The limiting plug-in 23 has a T-shaped structure as a whole. The limiting plug-in 23 includes a first limiting rod 231 and a second limiting rod 232. The first limiting rod 231 passes through the second earring 22 and the first earring 21 in sequence to form a limit. In addition, the limiting plug-in 23 can also be a U-shaped structure, with one end of the limiting plug-in 23 placed in the first earring 21 and the other end placed in the second earring 22.

[0041] During actual operation, the present invention also includes a tool box 41 located above the tool tray 4 and a plurality of tool support rods 42 connecting the tool box 41 and the bottom of the tool tray 4. The tool box 41 includes an annular plate 43 with an overall annular structure, a plurality of tool discharge rods 44 connected to the inner wall of the annular plate 43 and arranged at intervals from each other, and a tool discharge side plate connected to the outer wall of the annular plate 43 away from one end of the bottom plate of the tool tray 4 and parallel to the side wall of the tool tray 4.

[0042] In the above technical solution, a flip cover is provided at the upper end of the tool box 41, so that the staff can decide whether to close the tool box 41 according to their needs; under the function of the above tool box 41, the staff can place some tools needed for the current maintenance in the tool box 41, so as to reduce the time for the staff to find tools, thereby improving production efficiency; the tool support rod 42 can be a fixed rod with a fixed length, or it can be a telescopic rod, so that the staff can adjust the height of the tool box 41 according to their needs; the tool discharge rod 44 can be used to place maintenance tools, and the tool discharge side panel can play a certain limiting role.

[0043] The tool partitions 46 have an overall grid-like structure, with tool retaining holes provided at the nodes of the tool partitions 46. One end of the tool support rod 42 passes through the tool retaining holes and is detachably connected to the tool tray 4, while the other end is detachably connected to the annular plate 43. Due to the tool retaining holes, the present invention can more conveniently connect the tool support rod 42, tool tray 4, and tool box 41 into a single unit, which not only improves the structural stability of the present invention but also reduces the floor space occupied by the tool support rod 42 on the tool tray 4, allowing for more storage space on the work tray and enhancing the appearance of the present invention.

[0044] Preferably, a ring that can be sleeved on the tool support rod 42 is provided at the node of the tool partition 46 to further limit the support rod, thereby improving the structural stability of the tool tray 4; preferably, an internal thread is provided at the node of the tool partition 46 at the bottom of the tool tray 4, and an external thread is provided on the tool support rod 42, and the tool support rod 42 is detachably mounted on the tool tray 4 through a threaded connection; similarly, the annular plate 43 and the tool support rod 42 can also be installed together through a threaded connection.

[0045] A second receiving tray 52 is detachably placed on the upper end of the first receiving tray 51, and a receiving stopper 53 is provided between the first receiving tray 51 and the second receiving tray 52, passing through the first receiving tray 51 and the second receiving tray 52. ​​Thus, the present invention allows the second receiving tray 52 to continue receiving welding slag even if the first receiving tray 51 has already received enough welding slag, making the present invention more convenient to use.

[0046] Preferably, the side walls of the first receiving tray 51 and the side walls of the second receiving tray 52 are arranged to be inclined from the periphery of the first receiving tray 51 toward the center of the first receiving tray 51, that is, the side walls of the first receiving tray 51 and the second receiving tray 52 are both inclined side panels. With the effect of the inclined side panels, the present invention can more conveniently combine the first receiving tray 51 and the second receiving tray 52, thereby improving the ease of use of the present invention.

[0047] In actual operation, the middle of the first receiving tray 51 and the middle of the second receiving tray 52 are both provided with a receiving hole and a receiving groove 55 located above the receiving hole. The receiving limiter 53 includes a receiving limit vertical rod 56 and a receiving limit horizontal plate 57. The receiving limit vertical rod 56 passes through the receiving hole on the first receiving tray 51 and the receiving hole on the second receiving tray 52 in sequence, and the receiving limit horizontal plate 57 is located in the receiving groove 55 of the upper receiving tray (such as the second receiving tray 52). In this way, under the action of the above-mentioned receiving limiter 53, the connection between the first receiving tray 51 and the second receiving tray 52 is more firmly established, thereby making the structure of the present invention more stable.

[0048] The bottom plate of the container tray 6 is connected to a container partition 61 having an overall annular structure. Container hooks 62 are provided on both the outer and inner walls of the container partition 61. Thus, with the help of the container partition 61 and the container hooks 62, the present invention makes it more convenient to place the accessories in the tin pot on the easy tray.

[0049] Preferably, the tool partition 46 and / or container partition 61 are made of a material with a certain elasticity (such as rubber or a composite plate), wherein the thickness of the rubber is 2 to 3 cm, and the composite plate can be a polyamide plate or other plate with a certain elasticity, and the thickness of the composite plate can be 1 to 2 cm. At the same time, in order to improve the strength of the composite plate, the present invention can further add a certain proportion of glass fiber to the above-mentioned composite plate.

[0050] A slag hopper 71 is connected to the sidewall of the first and / or second discharge trays. A shovel 72 is also mounted on the sidewall of the slag hopper 71 for removing slag from the discharge trays. The shovel 72 can be used to remove welding slag from the first and / or second discharge trays, while the slag hopper 71 can be used to collect the slag removed from the first and / or second discharge trays, making the present invention more convenient to use.

[0051] In actual operation, the present invention further includes a guide rail 81 laid between the discharge tray and the container tray 6, a slider 82 slidably resting on the guide rail 81, a motor drive assembly mounted on the first receiving tray 51 or the container tray 6, and a fan 84 and / or a water gun mounted on the slider 82. The output end of the motor drive assembly is connected to the slider 82 and drives the slider 82 to slide along the guide rail 81. In this way, the motor drive assembly can drive the fan and / or water gun 84 to slide along the guide rail 81 via the slider 82, thereby cooling the high-temperature solder slag or accessories in the tin pot through the fan and / or water gun 84. This allows the present invention to further improve production efficiency in emergency situations (such as when meeting a deadline).

[0052] During operation, each discharge tray of the present invention can be independently moved and moved outward from the bottom of the device. The discharge tray can be welded from stainless steel and each is individually designed and equipped with four universal wheels. When the handle 31 is pulled, the discharge tray can be easily moved, facilitating cleaning of the open tank 1 after each shift.

[0053] During actual operation, the first earring 21 and the second earring 22 can be collectively referred to as earrings. A detachable connecting seat 2 is designed between the tool tray 4 and the slag receiving tray and between the slag receiving tray and the container tray 6. The detachable connecting seat 2 is used to lock the three discharge trays in combination. When the three slag receiving trays need to be combined into one, the limiting plug-in 23 (pin) is placed into the through hole of the first earring 21 and the first earring 21. The two limiting plug-ins 23 will connect the three discharge trays into one and prevent them from being separated. When it is necessary to use one of the tool trays 4 alone, such as pulling out the tool tray 4, it is only necessary to take out the limiting plug-in 23 between the tool tray 4 and the slag receiving tray. The removed limiting plug-in 23 can be placed again at the connection between the slag receiving tray and the container tray 6, or it can still be placed on the earring of the slag receiving tray to prevent the slag receiving tray from moving.

[0054] In a second aspect, the present invention further provides a wave soldering machine, comprising the aforementioned selective wave soldering machine slag removal device. Since this wave soldering machine has the aforementioned technical effects, a wave soldering machine comprising the aforementioned selective wave soldering machine slag removal device should also have the same technical effects. In actual operation, the specific definition of the commercial vehicle of the present invention can be found in the definition of the commercial vehicle front panel above and will not be elaborated here.

[0055] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0056] 1) In the SMT industry, the existing treatment methods for tin slag are mainly aimed at how to recycle and reuse the tin slag. At present, not only has there been no special solution for the operation and maintenance of the equipment itself, but there is also no container that can not only catch the splashed waste of the sprayed flux when the nozzle is working, but also can conveniently place the accessories in the tin pot during maintenance. Therefore, based on the solution of the above problems by the present invention, the technical solution described in the present invention deserves to be vigorously promoted.

[0057] 2) The combination of the three discharge trays of the present invention can be placed at the bottom of the selective wave soldering machine to receive the tin slag and solder resist splash residues generated when the bottom of the selective wave soldering machine is working; at the same time, each discharge tray of the present invention can be moved independently and moved out from the bottom of the equipment to the outside of the equipment. For example, when the container tray 6 is moved out along the side of the handle 31 alone, it can also be used to store accessories in the tin pot when repairing the tin pot; when the container tray 6 is moved out, the staff only needs to stand on the side of the tool tray 4 and the handle 31 of the slag tray, so that the present invention can be operated conveniently.

[0058] 3) The present invention can effectively protect against various dust, residues, tin slag and other wastes generated when the equipment is working; the size of each discharge tray can be designed in sections according to the size of the bottom of the equipment, and has strong adaptability; the present invention is flexible to use, which can meet the needs of welding operations and the placement of the tin pot along the line for maintenance and repair, and is safe and reliable; the discharge trays are easy to separate and move, and can be quickly assembled and fixed, with a simple structure and no need for special processing precision, so the present invention is easy to promote and apply to different models of equipment.
