Description

Technical Field

[0001] This invention relates to the field of welding molds, and more particularly to a magazine, a welding mold, and a welding method. Background Technology

[0002] A connector is a connecting device used to connect two active devices, often used to transmit current or signals. A typical connector includes a PCB board and a housing fitted onto the PCB board. One end of the PCB board has multiple solder pads for soldering to connecting wires to one of the active devices. The other end of the PCB board can be inserted into another active device through the housing to connect to that other active device.

[0003] In the connector manufacturing process, it is necessary to solder the connecting wires to the solder pads on the connector PCB board. Using a clip to tighten and fix the connector is a common soldering method to facilitate soldering with the connecting wires. Existing clips generally use a receiving groove that fits the shape of the connector to clamp and fix the connector. Understandably, the receiving groove usually needs to be slightly wider than the connector to fit the connector in. However, this leaves a gap between the connector and the receiving groove, which can cause the connector to wobble during the soldering process, resulting in inaccurate soldering. Summary of the Invention

[0004] The problem solved by this invention is how to provide a magazine, a welding mold, and a welding method that can more accurately fix the connector to facilitate welding.

[0005] To address the aforementioned problems, the present invention provides a magazine, comprising a magazine body and a magazine cover that is flip-open and folded at one end of the magazine body. The magazine body has a plurality of receiving slots arranged at intervals, each receiving slot having an open end for respectively engaging and placing a connector. When the magazine cover is closed, it presses against each connector. An elastic limiting member is provided on the left or right side of the receiving slot to elastically resist the connector, thereby pressing and fixing the connector to the side wall on the other side of the receiving slot.

[0006] Optionally, the side wall on the other side of the receiving groove is a limiting wall, which is provided with a side edge and a chamfer that fit and abut against the connector to position one side of the connector.

[0007] Optionally, the elastic limiting member includes a mounting shaft, an elastic element, and a rotating block. The mounting shaft is rotatably disposed on one side of the receiving groove, the rotating block is sleeved on the mounting shaft, and the elastic element is disposed on the side of the rotating block away from the receiving groove and abuts against the fixed wall adjacent to the rotating block, so that the rotating block rotates towards the receiving groove, thereby pushing the connector in the receiving groove to abut against the limiting wall.

[0008] Optionally, a barrier is provided between the receiving groove and the elastic limiting member. One side of the barrier forms the groove wall of the receiving groove, and the other side of the barrier is spaced apart from the rotating block and abuts against the rotating block after rotation, so as to limit the rotation range of the rotating block.

[0009] Optionally, one end of the magazine cover is rotatably disposed on the end of the magazine body opposite to the opening of the receiving groove, and a plurality of protruding pressing blocks are provided at intervals on the bottom of the magazine cover to press and fix each of the connectors.

[0010] Compared to the advantages of existing technologies, the magazine body of this invention has multiple receiving slots arranged linearly at intervals, with one end of each receiving slot open. This allows the end of each connector exposed on the PCB board to face the open end of the receiving slot, facilitating subsequent soldering of connecting wires to the solder pads on the PCB board. Each connector is snapped into its respective receiving slot. One side of each receiving slot has an elastic limiting member that springs against the connector, pressing and fixing the connector to the other side of the receiving slot opposite the elastic limiting member. On the side wall, the other side wall of the receiving groove opposite to the elastic limiting member is a reference wall. When the connector is fully fitted with the reference wall, each solder pad on the PCB board can be precisely aligned with the connecting line for soldering. After the spring clip cover is fastened, it can press each connector from above, thereby further fixing the connector. Thus, the setting of the elastic limiting member can prevent the connector from swinging during the soldering process due to the receiving groove being too wide, and the setting of the spring clip cover further clamps and fixes the connector, thereby improving the soldering accuracy.

[0011] The present invention also provides a welding mold, including a magazine as described above and a positioning mold connected to the magazine. The positioning mold includes a mold body and a flip-top opening clamp plate disposed on one side of the mold body. A plurality of limiting channels are arranged at intervals on the mold body. Each limiting channel is adapted to hold and place a connecting wire, so that one end of each connecting wire after being stripped and shaped and having multiple single wires is respectively positioned at the welding position of each connector.

[0012] Optionally, a single-line positioning component is provided at one end of the limiting channel near the receiving groove. The single-line positioning component includes two support components spaced apart on both sides of the limiting channel, and a fixing component that is respectively engaged with each of the support components at both ends. The fixing component has multiple wire holes arranged on it so that each single line passes through in an orderly manner and is fixed.

[0013] Optionally, multiple positioning elements are also provided on both sides of the limiting channel, with each positioning element spaced at intervals, to position the connecting line within the limiting channel.

[0014] Optionally, one end of the clamping plate is rotatably disposed on one side of the mold body, and the other end of the clamping plate is fastened to the other side of the mold body. The clamping plate is used to fasten and press each of the connecting lines. The clamping plate is provided with a plurality of inclined pressing heads, and the bottom of the pressing heads is pressed onto the fixing member for further pressing and fixing.

[0015] Since the welding mold includes a magazine, the welding mold has at least the beneficial effects of the magazine, which will not be elaborated here.

[0016] The present invention also provides a welding method based on a welding mold as described above, comprising the following steps:

[0017] Multiple connectors are placed in an orderly manner in the receiving slots of the magazine body after the elastic limiting member is opened. After the elastic limiting member is reset, the connector is pressed against the side wall of the receiving slot. Finally, the magazine cover is fastened to press each connector tightly from above.

[0018] Multiple connecting wires are respectively inserted and placed along the limiting channels of the mold body, so that the multiple single wires exposed after the connecting wires are stripped and shaped pass through multiple wire holes on the fixing parts for positioning. Finally, the clip cover is fastened to press the connecting wires from above, and at the same time, the fixing parts are pressed.

[0019] The magazine and the positioning mold are assembled together. After the assembly is completed, the welding ends of the multiple single wires after the connecting wires are stripped and shaped are respectively positioned at the welding positions of the connectors, and then welding is performed.

[0020] Since the welding method is based on a welding mold, the welding method has at least the beneficial effects of the welding mold, which will not be elaborated here. Attached Figure Description

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or implementation. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or implementations.

[0031] The present invention will now be described in detail with reference to the accompanying drawings.

[0032] To solve the above technical problems, combined with Figure 1 As shown, an embodiment of the present invention provides a magazine, including a magazine body 1 and a magazine cover 2 that is flip-topped and folded at one end of the magazine body 1. The magazine body 1 has a plurality of receiving slots 3 arranged at intervals, and one end of each receiving slot 3 is open to be adapted to respectively hold and place a connector 9. After the magazine cover 2 is fastened, it presses against each of the connectors 9. An elastic limiting member 4 is provided on the left or right side of the receiving slot 3 to elastically abut against the connector 9, so as to press and fix the connector 9 on the side wall of the other side of the receiving slot 3.

[0033] It should be noted that, optionally, the magazine body 1 has a plurality of receiving slots 3 arranged linearly at intervals, with one end of each receiving slot 3 open, so that the end of each connector 9 exposed on the PCB board faces the open end of the receiving slot 3, so as to facilitate the subsequent soldering of the connecting wires 10 to the solder pads on the PCB board. Each connector 9 is respectively snapped into the receiving slot 3. One side of the receiving slot 3 is provided with an elastic limiting member 4 that elastically abuts against the connector 9. The elastic limiting member 4 can press and fix the connector 9 to the other side wall of the receiving slot 3 opposite to the elastic limiting member 4. In the above, the other side wall of the receiving groove 3 opposite to the elastic limiting member 4 is a reference wall. When the connector 9 is fully fitted with the reference wall, each solder foot on the PCB board can be precisely aligned with the connecting line 10 for welding. After the spring clip cover 2 is fastened, it can press each connector 9 from above, thereby further fixing the connector 9. Thus, the setting of the elastic limiting member 4 can prevent each receiving groove 3 from being too wide, causing the connector 9 to swing during the welding process. The setting of the spring clip cover 2 further clamps and fixes the connector 9, thereby improving the welding accuracy.

[0034] In one embodiment of the present invention, combined with Figure 1As shown, the side wall on the other side of the receiving groove 3 is a limiting wall 6a. The limiting wall 6a is provided with a side edge and a chamfer that fit and abut against the connector 9 to position one side of the connector 9.

[0035] It should be noted that the side wall on the other side of the receiving groove 3 is a limiting wall 6a. The receiving groove 3 includes a first receiving groove 31 for accommodating the outer shell portion of the connector 9, and a second receiving groove 32 connected to the first receiving groove 31 for accommodating the exposed PCB portion of the connector 9. The side of the second receiving groove 32 away from the first receiving groove 31 is open. Optionally, one side wall of the first receiving groove 31 and one side wall of the second receiving groove 32 are integrally formed as the limiting wall 6a. The limiting wall 6a has a side edge and a chamfer that abut against the connector 9, thereby allowing the limiting wall 6a to completely... The elastic limiting member 4 is positioned to fit one side of the connector 9, so that when the connector 9 is abutted against the limiting wall 6a, the limiting wall 6a can perfectly fit the connector 9, thereby achieving precise positioning of the connector 9 and facilitating the soldering of each solder pin on the PCB board of the connector 9. Optionally, a limiting strip 6 can be set between the two receiving grooves 3, and the side walls on the left and right sides of the limiting strip 6 respectively form the limiting walls 6a of the two adjacent receiving grooves 3. This allows for the efficient use of the positions on the magazine body 1 to set as many receiving grooves 3 as possible, increasing the number of connectors 9 that the magazine can fix, thereby improving soldering efficiency.

[0036] In one embodiment of the present invention, combined with Figure 1 As shown, the elastic limiting member 4 includes a mounting shaft, an elastic member, and a rotating block. The mounting shaft is rotatably disposed on one side of the receiving groove 3. The rotating block is sleeved on the mounting shaft. The elastic member is disposed on the side of the rotating block away from the receiving groove 3 and abuts against the fixed wall adjacent to the rotating block, so that the rotating block rotates towards the receiving groove 3, thereby pushing the connector 9 in the receiving groove 3 to abut against the limiting wall 6a.

[0037] It should be noted that a hollowed-out mounting hole is provided on the magazine body 1 on one side of the receiving groove 3, that is, on the side opposite to the limiting wall 6a. The two ends of the mounting shaft are rotatably mounted on the magazine body 1 at both ends of the mounting hole, so that the mounting shaft is longitudinally rotated along the side wall of the receiving groove 3. The rotating block is sleeved on the mounting shaft along the axial direction of the mounting shaft. The elastic element is provided on the side of the rotating block away from the receiving groove 3. The rotating block is provided with a slot that matches one end of the elastic element. The fixed wall adjacent to the rotating block is also provided with a slot that matches the other end of the elastic element. Optionally, located in The fixing walls of the two accommodating slots 3 can be the inner side walls of the magazine body 1. A fixing block 7 can be set between two adjacent accommodating slots 3 in the middle, with the fixing block 7 facing the side walls of the two accommodating slots 3 as the fixing wall, so that the space on the magazine body 1 can be reasonably utilized. Preferably, the elastic element is a spring or a spring block, so that the elastic element can drive the rotating block to rotate towards the accommodating slot 3. Optionally, the side of the rotating block near the connector 9 is fitted with the connector 9, so that the connector 9 can be pressed and fixed on the limiting wall 6a more stably.

[0038] In one embodiment of the present invention, combined with Figure 1 As shown, a barrier 5 is provided between the receiving groove 3 and the elastic limiting member. One side of the barrier 5 forms the groove wall of the receiving groove 3, and the other side of the barrier 5 is spaced apart from the rotating block and abuts against the rotating block after rotation, so as to limit the rotation range of the rotating block.

[0039] It should be noted that, optionally, the first receiving groove 31 is provided with the blocking member 5 on the side opposite to the limiting wall 6a. The blocking member 5 is spaced apart from the limiting member. One side of the blocking member 5 forms the side wall of the receiving groove 3. The second receiving groove 32 is open on the side opposite to the limiting wall 6a. Thus, when the rotating block rotates toward the receiving groove 3, part of the rotating block can elastically press against the connector 9, while the remaining part of the rotating block abuts against the blocking member 5. This allows control over the force and amplitude of the rotating block pressing against the connector 9, preventing excessive pressure from damaging the connector 9 and improving the safety performance of the magazine.

[0040] In one embodiment of the present invention, combined with Figure 1 As shown, one end of the magazine cover 2 is rotatably disposed on the end of the magazine body 1 away from the opening end of the receiving groove 3, and a plurality of protruding pressing blocks 21 are provided at intervals on the bottom of the magazine cover 2 to press and fix each of the connectors 9.

[0041] It should be noted that a rotating shaft is provided on the end of the magazine body 1 facing away from the opening of the receiving groove 3. One end of the magazine cover 2 is sleeved on the rotating shaft, so that the magazine cover 2 can be rotated and fastened to the magazine body 1. A plurality of protruding pressing blocks 21 are provided on the side of the magazine cover 2 facing each of the receiving grooves 3, so that when the magazine cover 2 is fastened, it can press on the connector 9 in each of the receiving grooves 3, thereby further pressing the connector 9 to prevent loosening. The magazine cover 2 and the magazine body 1 can be magnetically fastened together.

[0042] This invention also provides a welding mold, including a magazine as described above and a positioning mold connected to the magazine. The positioning mold includes a mold body 11 and a flap-type clamping plate 12 disposed on one side of the mold body 11. The mold body 11 is provided with a plurality of limiting channels arranged at intervals. Each limiting channel is adapted to hold and place a connecting wire 10, so that one end of each connecting wire 10 after being stripped and shaped, having multiple single wires 101, is respectively positioned at the welding position of each connector 9.

[0043] It should be noted that the welding mold includes a magazine and a positioning mold connected to the magazine. Optionally, the positioning mold is inserted into the magazine on the side facing the opening of the receiving groove 3 via pins 8, so as to facilitate the subsequent soldering of the connecting wire 10 to the PCB board. The magazine body 1 is provided with a plurality of protruding pins 8, and the mold body 11 is provided with corresponding pin 8 holes, so that they can be inserted into each other. Optionally, the mold body 11 and the magazine body 1 can also be magnetically attached. A magnetic block is built into the side of the mold body 11 adjacent to the magazine body 1 to attract each other, so that the magazine and the positioning mold can be stably connected and facilitate welding. The positioning mold includes a mold body 11 and a clamping plate 1 that is flip-open and closed on one side of the mold body 11. 2. The mold body 11 is provided with multiple limiting channels arranged at intervals. Each limiting channel is arranged longitudinally at intervals and is respectively positioned towards the opening end of each receiving groove 3. Each limiting channel is suitable for clamping and placing connecting wires 10, thereby positioning each connecting wire 10. After peeling and shaping, one end of each connecting wire 10 with multiple single wires 101 is positioned on each solder pad of the PCB board for subsequent soldering. It can be understood that the peeling and shaping involves removing the insulating sleeve of one end of the connecting wire 10 and adjusting the spacing and shape of each single wire 101 so that the end of each single wire 101 can be adapted to each solder pad. The positioning mold can cooperate with the spring clip to perform soldering positioning of multiple connectors 9 and connecting wires 10, which is convenient, fast and accurate.

[0044] In one embodiment of the present invention, combined with Figure 1 As shown, a single-line positioning member 111 is provided at one end of the limiting channel near the receiving groove 3. The single-line positioning member 111 includes two support members A1 spaced apart on both sides of the limiting channel, and a fixing member A2 that is respectively engaged with each of the support members A1 at both ends. Multiple wire holes are arranged on the fixing member A2 so that each single line 101 passes through in an orderly manner and is fixed.

[0045] It should be noted that a single-line positioning component 111 is provided at one end of the limiting channel near the receiving groove 3. The single-line positioning component 111 is provided on the mold body 11. The single-line positioning component 111 includes two support components A1 spaced apart on both sides of the limiting channel. A snap-fit ​​groove is provided on the opposite side of the two support components A1. The two ends of the fixing component A2 are respectively provided with shapes that are adapted to each snap-fit ​​groove, so that they can be snapped between the two support components A1. Multiple wire holes are longitudinally provided on the fixing component A2, so that each of the single wires 101 can pass through in an orderly manner and connect to each of the welding feet of the connecting plate, thereby accurately controlling the connection position of each single wire 101 to each welding foot.

[0046] In one embodiment of the present invention, combined with Figure 1 As shown, multiple positioning elements 111 are also provided on both sides of the limiting channel, and each positioning element 111 is arranged at intervals to position the connecting line 10 in the limiting channel.

[0047] It should be noted that multiple positioning elements 111 are also provided on both sides of the limiting channel. The position and shape of each positioning element 111 are set according to the shape of the connecting line 10 in the limiting channel, so as to fit and limit the connecting line 10. Optionally, a pair of positioning elements 111 are provided at the place where the connecting line 10 is connected to each of the single lines 101, and a pair of positioning elements 111 are provided at the other end of the connecting line 10 away from each of the single lines 101, so as to stably position the entire connecting line 10 and prevent the connecting line 10 from deviating and affecting the welding.

[0048] In one embodiment of the present invention, combined with Figure 1 As shown, one end of the clamping plate 12 is rotatably disposed on one side of the mold body 11, and the other end of the clamping plate 12 is fastened to the other side of the mold body 11. The clamping plate 12 is used to fasten and press each of the connecting lines 10. The clamping plate 12 is provided with a plurality of inclined pressing heads 121. The bottom of the pressing head 121 is pressed and disposed on the fixing member A2 for further pressing and fixing.

[0049] It should be noted that a rotating shaft 112 is provided on the left or right side of the mold body 11. One end of the clamping plate 12 is sleeved on the rotating shaft 112, so that it can be rotated and fastened to the mold body 11 to press and fix each of the connecting lines 10 from above. The other end of the clamping plate 12 can be magnetically attracted to the mold body 11 for fastening. Multiple inclined pressing heads 121 are arranged at intervals on the side of the clamping plate 12 facing each of the fixing members A2. Preferably, there are two. When the clamping plate 12 is fastened, one pressing head 121 presses two adjacent fixing members A2 at the same time, thereby simplifying the structure of the clamping plate 12. The inclined design facilitates the precise pressing of each pressing head 121.

[0050] This invention also provides a welding method based on a welding mold as described above, comprising the following steps:

[0051] Multiple connectors 9 are placed in the respective receiving slots 3 of the magazine body 1 after the elastic limiting member 4 is opened. After the elastic limiting member 4 is reset, the connectors 9 are pressed against the side wall of the receiving slot 3. Finally, the magazine cover 2 is fastened to press each connector 9 from above.

[0052] Multiple connecting wires 10 are respectively snapped into place along the limiting channels of the mold body 11, so that the multiple single wires 101 exposed after the stripping and shaping of each connecting wire 10 pass through multiple wire holes on the fixing member A2 for positioning. Finally, the clip cover 2 is fastened to press each connecting wire 10 from above, and at the same time, each fixing member A2 is pressed.

[0053] The magazine and the positioning mold are assembled together. After the assembly is completed, the welding ends of the multiple single wires 101 of each connecting line 10 after being stripped and shaped are respectively positioned at the welding positions of each connector 9, and then welding is performed.

[0054] It should be noted that the welding method is implemented based on the welding mold. First, multiple connectors 9 are arranged and fixed in the magazine. Then, multiple connecting wires 10 are arranged and fixed in the positioning mold. Finally, the magazine and the positioning mold are connected by mutual insertion, so that the ends of multiple single wires 101 of each connecting wire 10 are respectively set on the solder pins of each connector 9 PCB board. This allows for stable pre-welding positioning of multiple connectors 9 and connecting wires 10 in one go. If a robotic arm is used on the welding table to install the connecting wires 10 and the connectors 9 and to mutually insert the magazine and the positioning mold, and then the welding head directly performs the welding, fully automated unmanned welding can be achieved, thus improving welding efficiency.

[0055] It should be noted that the above-mentioned technical features can be combined with each other to form various embodiments not listed above, all of which are considered to be within the scope of this invention specification; and, for those skilled in the art, improvements or modifications can be made based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
