Description

Technical Field

[0001] The utility model relates to the technical field of welding, in particular to a PCB board welding positioning mechanism and high-frequency double-sided welding equipment. Background Art

[0002] Existing electrical connection structures include single-wire connections and multi-wire connections. Multi-wire connections enable multifunctional use and are increasingly used. Multi-wire connected electrical components generally require multiple wire harnesses to be welded simultaneously on a circuit board. To increase the number of wire harnesses, multiple insulated wire harnesses are welded on both sides of the circuit board. In actual manufacturing, welding multiple wire harnesses requires special attention to welding quality and stability. Because the number of wires in a harness is large, any welding problems can affect the normal operation of the entire circuit. Therefore, when welding multi-core wire harnesses, special technical measures are required to ensure welding quality and stability.

[0003] The inventors have found that the welding equipment for welding multiple wire harnesses on a circuit board in the related art has at least the following disadvantages:

[0004] When double-sided soldering on a circuit board, one side is usually soldered first, and then the other side is soldered after repeated positioning. In addition, when soldering each side, the wire harness is manually positioned on the circuit board, which is time-consuming, labor-intensive, and inefficient. In addition, large errors lead to poor soldering quality. Utility Model Content

[0005] The purpose of the utility model includes providing a PCB board welding positioning mechanism and a high-frequency double-sided welding device, which can improve the stability of the relative position of the wire harness and the circuit board body, the wire harness position is not easy to move during welding, the welding quality is high, and no manual positioning is required, which saves time and effort and is highly efficient.

[0006] The embodiment of the present utility model can be implemented as follows:

[0007] In a first aspect, the utility model provides a PCB board welding positioning mechanism, comprising:

[0008] The line card body is provided with a first side surface, a second side surface and a third side surface connected in sequence, and the second side surface is located between the first side surface and the third side surface; the second side surface is provided with a positioning groove for plugging the circuit board body; the first side surface and the third side surface are both provided with positioning card slots for positioning the wiring harness.

[0009] In an optional embodiment, the positioning groove is provided with a guide groove section, the first end of the guide groove section is spaced apart from the bottom wall of the positioning groove, the second end of the guide groove section opposite to the first end extends to the slot opening of the positioning groove, and the slot width of the guide groove section gradually decreases in the direction from the slot opening of the positioning groove to the slot bottom.

[0010] Based on the above solution, by providing a guide slot segment with a maximum slot width, one side of the circuit board body enters through the guide slot segment, minimizing interference with the end surface of the guide slot segment's slot opening, making it easier for the circuit board body to be inserted into the positioning groove. Furthermore, the circuit board body contacts the slot walls of the guide slot segment, which guide the circuit board body into position where it contacts the slot bottom wall. This makes assembly of the line card body and the circuit board body convenient and reliable.

[0011] In an optional embodiment, at least a portion of the groove wall of the positioning groove is configured as an elastic wall to adaptively adjust the groove width according to the shape of the circuit board body.

[0012] Based on the above solution, the groove wall of the positioning groove is set as an elastic wall, and the elastic wall has a certain deformation ability. When the circuit board body is inserted into the positioning groove, the circuit board body contacts the elastic wall and can squeeze the elastic wall, so that the groove width of the positioning groove can be adaptively changed. The positioning groove can position circuit board bodies of different sizes, and also improves the problem of poor assembly quality caused by manufacturing errors.

[0013] In an optional embodiment, the bottom wall of the positioning slot is configured as an arc-shaped surface.

[0014] Based on the above solution, the positioning slot is used to position the wire harness welded to the circuit board body.

Therefore, after the wire harness is inserted into the positioning slot, the insulating layer wrapped around the outside of the wire harness contacts the bottom wall of the positioning slot, the contact area is large, the combination is tight, and the positioning effect is good.

[0015] In an optional embodiment, the positioning slot is provided with a first slot side wall and a second slot side wall opposite to each other, and the first slot side wall and the second slot side wall are respectively connected to two sides of the slot bottom wall.

[0016] Based on the above solution, after the wire harness is inserted into the positioning card slot, the insulating layer wrapped around the outside of the wire harness is in close contact with the curved surface, which plays a positioning role. At the same time, the side wall of the first slot and the side wall of the second slot cooperate to form a clamping space to prevent the wire harness from detaching from the positioning card slot, thereby improving the stability of the combination of the wire harness and the wire card body.

[0017] In an optional embodiment, the line card body further has a fourth side and a fifth side facing each other, the first side, the second side and the third side are all located between the fourth side and the fifth side; the fourth side and the fifth side are provided with concave and convex portions for engaging with the welding platform.

[0018] In an optional embodiment, the number of the line card bodies is two and they are arranged opposite to each other, and the two line card bodies are used to be positioned on opposite sides of the circuit board body, respectively.

[0019] Based on the above solution, the two wire card bodies cooperate to simultaneously position the wire harnesses to be welded on both sides of the circuit board body, and the two wire card bodies clamp the circuit board body, which facilitates positioning the position of the circuit board body, thereby facilitating simultaneous welding of the wire harnesses on both sides of the circuit board body and improving welding efficiency.

[0020] In a second aspect, the utility model provides a high-frequency double-sided welding device, the high-frequency double-sided welding device comprising:

[0021] The PCB board welding positioning mechanism according to any one of the aforementioned embodiments.

[0022] In an optional embodiment, the high-frequency double-sided welding equipment also includes a welding platform and two welding robotic arms, the line card body is positioned on the welding platform, and the two welding robotic arms are both installed on the welding platform and located on both sides of the line card body in the arrangement direction of the first side and the third side.

[0023] Based on the above solution, two welding robot arms can simultaneously weld the wiring harnesses on the two surfaces of the circuit board body with high efficiency.

[0024] In an optional embodiment, a positioning jig is installed on the welding platform, and the positioning jig is provided with an avoidance through hole. The line card body is clamped in the positioning jig so that the circuit board body is exposed in the avoidance through hole.

[0025] Based on the above solution, the upper and lower welding robotic arms can be located in the avoidance through-hole at the same time to weld the wiring harnesses on both sides of the circuit board body, which is less likely to cause interference and welding accidents.

[0026] The beneficial effects of the PCB board welding positioning mechanism and high-frequency double-sided welding equipment provided by the embodiment of the utility model include:

[0027] In summary, the PCB board welding positioning mechanism provided in this embodiment, before welding, according to the welding requirements, the line card body is connected to one side of the circuit board body using the positioning card slot thereon, and the positions of the line card body and the circuit board body are relatively fixed. At the same time, the wire harness to be welded is placed in the positioning card slot corresponding to the line card body. The position of the wire harness is positioned by the positioning card slot. In this way, the relative position of the wire harness and the circuit board body is maintained. Then, the assembled circuit board body, line card body and wire harness are placed together on the welding platform. Obviously, a positioning fixture for positioning the line card body can be set on the welding platform to improve the stability of the relative position between the line card body and the welding robot arm. Start the welding equipment, the welding robot arm approaches the circuit board body and the wire harness, and welds the wire harness to the circuit board body.

DETAILED DESCRIPTION

[0034] In the prior art, in order to weld multiple wire harnesses 002 on the two surfaces of the circuit board body 001, each wire harness 002 is generally welded independently. This is cumbersome and inefficient. In addition, the positioning of multiple wire harnesses 002 is manual, resulting in large errors and low welding quality.

[0035] In view of this, the designer provides a PCB board welding positioning mechanism, which can simultaneously position multiple wire harnesses 002 to be welded on the two board surfaces of the circuit board body 001, with good positioning effect, and can weld the wire harnesses 002 on the two board surfaces of the circuit board body 001 at the same time, with high efficiency.

[0041] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention can be combined with each other.

[0042] The overall structure, working principle and technical effects of the PCB board welding positioning mechanism provided by the present invention are described in detail below through embodiments and in conjunction with the accompanying drawings.

[0043] Please refer to Figure 1 and Figure 3 The PCB board welding positioning mechanism provided by the utility model is used for simultaneous welding of a circuit board and multiple wire harnesses 002.

[0044] Please combine Figure 2 The PCB board welding positioning mechanism includes a line card body 100, which is provided with a first side surface 110, a second side surface 120 and a third side surface 130 connected in sequence, and the second side surface 120 is located between the first side surface 110 and the third side surface 130; the second side surface 120 is provided with a positioning groove 160 for plugging the circuit board body 001; the first side surface 110 and the third side surface 130 are both provided with a positioning card slot 170 for positioning the wiring harness 002.

[0045] Based on the above, the PCB board welding positioning mechanism provided in this embodiment is used as follows:

[0046] Before soldering, based on the soldering requirements, the line card body 100 is clipped onto one side of the circuit board body 001 using the positioning slots 170 thereon. The positions of the line card body 100 and the circuit board body 001 are relatively fixed. At the same time, the wire harness 002 to be soldered is placed in the corresponding positioning slots 170 of the line card body 100. The position of the wire harness 002 is determined by the positioning slots 170. In this way, the relative position of the wire harness 002 and the circuit board body 001 is maintained. Then, the assembled circuit board body 001, line card body 100, and wire harness 002 are placed together on the soldering platform. Obviously, a positioning fixture can be set on the soldering platform to position the line card body 100, thereby improving the stability of the relative position between the line card body 100 and the soldering robot arm. The soldering equipment is started, and the soldering robot arm approaches the circuit board body 001 and wire harness 002 to solder the wire harness 002 to the circuit board body 001. Due to the cooperation of the two welding robot arms, the wiring harnesses 002 on the two surfaces of the circuit board body 001 can be welded simultaneously, with high welding efficiency and high welding quality.

[0047] The following embodiments illustrate the detailed structure of the PCB board welding positioning mechanism provided in this application by way of examples.

[0048] In this embodiment, the positioning groove 160 is optionally provided with a guide groove section 161. A first end of the guide groove section 161 is spaced apart from the bottom wall of the positioning groove 160. A second end of the guide groove section 161, opposite the first end, extends to the opening of the positioning groove 160. The width of the guide groove section 161 gradually decreases from the opening to the bottom of the positioning groove 160. In other words, the position near the opening of the positioning groove 160 is configured to have a gradually changing width. For example, if the positioning groove 160 is a rectangular groove, the cross-section of the guide groove section 161 can be configured to have a rectangular shape. In this way, the guide groove section 161 has four groove sidewalls connected end to end, each groove sidewall forming an obtuse angle with the bottom wall of the positioning groove 160, and the four groove sidewalls form an open structure.

[0049] It should be understood that by providing guide slot section 161, the width of the slot opening of guide slot section 161 is maximized, and one side of circuit board body 001 enters through guide slot section 161 without interfering with the end face of guide slot section 161 where the slot opening is located. This facilitates insertion of circuit board body 001 into positioning groove 160. Furthermore, circuit board body 001 contacts the groove walls of guide slot section 161, which guide the circuit board body into position where it contacts the groove bottom wall. This makes assembly of line card body 100 and circuit board body 001 convenient and reliable.

[0050] Optionally, at least a portion of the groove wall of the positioning groove 160 is configured as an elastic wall to adaptively adjust the groove width according to the shape of the circuit board body 001. For example, the four groove side walls of the positioning groove 160 are configured as elastic walls with a certain degree of deformation.

[0051] In actual use, the groove wall of the positioning groove 160 is set as an elastic wall, and the elastic wall has a certain deformation ability. When the circuit board body 001 is inserted into the positioning groove 160, the circuit board body 001 contacts the elastic wall and can squeeze the elastic wall, so that the groove width of the positioning groove 160 can be adaptively changed. The positioning groove 160 can position circuit board bodies 001 of different sizes, and also improves the problem of poor assembly quality caused by manufacturing errors.

[0052] In this embodiment, the number of positioning slots 170 on the first side 110 and the third side 130 can optionally be set to be the same, and the arrangement and structural form of the multiple positioning slots 170 can be set to be the same, which facilitates processing and manufacturing. In this embodiment, to avoid repetition and redundancy, the positioning slots 170 on the first side 110 or the third side 130 are used as an example for description.

[0053] Optionally, the bottom wall of the positioning slot 170 is configured as an arcuate surface 171. For example, the bottom wall of the positioning slot 170 is configured as a semicircular arcuate surface 171, that is, the cross-sectional profile of the bottom wall of the positioning slot 170 is semicircular. The positioning slot 170 is used to position the wiring harness 002 welded to the circuit board body 001. The outside of the wiring harness 002 is generally wrapped with an insulating layer, and the wiring harness 002 is generally cylindrical. Therefore, after the wiring harness 002 is inserted into the positioning slot 170, the insulating layer wrapped around the outside of the wiring harness 002 contacts the bottom wall of the positioning slot 170, resulting in a large contact area, a tight connection, and a good positioning effect.

[0054] In this embodiment, the positioning slot 170 is optionally provided with a first slot sidewall 172 and a second slot sidewall 173 that are opposite to each other. The first slot sidewall 172 and the second slot sidewall 173 are respectively connected to the two sides of the slot bottom wall. The first slot sidewall 172 and the second slot sidewall 173 are both planar walls. The first slot sidewall 172 and the second slot sidewall 173 are arranged in parallel and spaced apart, and are both tangent to the arcuate surface 171. In this way, the first slot sidewall 172 and the second slot sidewall 173 play the role of guiding the wiring harness 002 to be inserted into the arcuate surface 171, and also prevent the wiring harness 002 from being dislodged from the positioning slot 170 after being inserted.

[0055] That is to say, after the wire harness 002 is inserted into the positioning slot 170, the insulating layer wrapped around the outside of the wire harness 002 is in close contact with the arc surface 171, which plays a positioning role. At the same time, the first slot side wall 172 and the second slot side wall 173 cooperate to form a clamping space to prevent the wire harness 002 from detaching from the positioning slot 170, thereby improving the stability of the combination of the wire harness 002 and the wire card body 100.

[0056] In this embodiment, the line card body 100 optionally further has a fourth side surface 140 and a fifth side surface 150 that are opposed to each other. The first side surface 110, the second side surface 120, and the third side surface 130 are all located between the fourth side surface 140 and the fifth side surface 150. The fourth side surface 140 and the fifth side surface 150 are provided with concave and convex portions for engaging with the soldering platform. For example, protrusions can be provided on the fourth side surface 140 and the fifth side surface 150. The protrusions can be engaged with a positioning fixture to enhance the secure connection between the line card body 100 and the positioning fixture.

[0057] It should be noted that there are two line card bodies 100 arranged opposite each other, and the two line card bodies 100 are used to be positioned on opposite sides of the circuit board body 001. The two line card bodies 100 cooperate to simultaneously position the wire harnesses 002 to be soldered on both sides of the circuit board body 001. The two line card bodies 100 clamp the circuit board body 001, facilitating the positioning of the circuit board body 001 and facilitating simultaneous soldering of the wire harnesses 002 on both sides of the circuit board body 001, thereby improving soldering efficiency.

[0058] In this embodiment, the design of the PCB board welding positioning mechanism can simultaneously weld multiple wire harnesses 002 on the two board surfaces of the circuit board body 001, with high efficiency and high welding quality.

[0059] In actual application, the number of positioning slots 170 on the wire card body 100 is set as needed, and according to welding requirements, the wire harness 002 can be connected to the corresponding positioning slot 170, without having to set a wire harness 002 in each positioning slot 170. It can be used as needed, which is flexible and convenient.

[0060] After the double-sided welding of the circuit board body 001 is completed, multiple wire harnesses 002 are welded on the two opposite sides of the circuit board body 001. The circuit board body 001 and the wire harness 002 can be connected to electrical components as needed, and have a wide range of uses.

[0061] This embodiment also provides a high-frequency double-sided welding device, including a welding platform, a positioning jig, two welding robotic arms and the PCB board welding positioning mechanism of the above embodiment. The bottom of the welding platform can be provided with brakeable walking wheels to facilitate movement and positioning after movement. The positioning jig is installed on the welding platform, and an avoidance through-hole is provided in the middle of the positioning jig. The positioning jig can include a structure with two hinged plates, and the two plates can rotate relative to each other to open or close. When opened, the line card body 100, the circuit board body 001 and the wires can be placed between the two plates for preliminary positioning. Then, the two plates are closed, and the line card body 100 is clamped by the two plates. The position where the wire harness 002 and the circuit board body 001 are to be welded is exposed in the avoidance through-hole. During welding, the wire harness 002 on the two surfaces of the circuit board body 001 is welded simultaneously by the two welding robotic arms installed on the welding platform, which is efficient and has high welding quality.

[0062] The above is only a specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
