Description

Technical Field

[0001] The utility model relates to the technical field of welding tooling, and particularly relates to a convenient wire clamping and rapid positioning wire welding tooling. Background Technique

[0002] At present, in the automatic soldering and wire welding operations of 2.4GHz and 5GHz PCB antenna boards, the wire clamping and auxiliary positioning soldering tooling generally uses a structural method of clamping a cable by folding upper and lower two-layer clamping plates through hinges. First of all, this type of tooling is relatively bulky. Each time of welding requires placing the circuit board on the lower layer plate and the wire on the upper layer plate respectively first, then closing the upper and lower two-layer clamping plates and placing them on the welding machine. After welding is completed, the tooling is taken off, a new tooling is placed, and then the previously used tooling is opened to take off the welded circuit board and place new materials. Facing nearly a thousand times of tooling placement operations every day, it really brings a heavy physical burden to the operator. Secondly, the tooling with a group of upper and lower two-layer clamping plates has a relatively high production cost. Finally, the positioning gap of the hinge is relatively large, the positioning accuracy is not high, and it is easily deformed by external force collision, directly affecting the service life of the tooling.

[0003] The technical problem to be solved by this application is: how to solve the problems of low reliability, bulkiness and low efficiency of the existing circuit board welding tooling. Content of the Utility Model

[0004] In order to overcome the deficiencies of the prior art, the purpose of the utility model is to provide a convenient wire clamping and rapid positioning wire welding tooling, which has the characteristics of simple structure, convenient operation and high working efficiency.

[0005] The technical solution adopted by the utility model is: a convenient wire clamping and rapid positioning wire welding tooling, which includes a base and a positioning plate detachably connected to the base. A positioning groove for placing a circuit board is provided on the base, and the shape of the positioning groove matches the shape of the circuit board. A plurality of card slots for clamping wires are provided at intervals on the side of the positioning plate opposite to the positioning groove. A positioning pin is also provided on the base, and a positioning hole corresponding to the positioning pin is provided on the positioning plate.

[0006] The convenient wire clamping and rapid positioning wire welding tooling of the utility model sets the base and the positioning plate as a separable structure, so that each base can correspond to multiple positioning plates. In some cases, when changing different production products, only the positioning plate needs to be replaced, and the base does not need to be replaced, which can effectively reduce the manufacturing cost of the tooling. At the same time, multiple positioning plates can clamp wires simultaneously, which can improve the flow rate of the welding operation, ensure that the automatic soldering machine operates without interruption, and maximize the efficiency of the equipment; the separable base can be directly fixed on the working slider of the automatic soldering machine, reducing the positioning error caused by repeated picking and placing of the tooling; in each wire welding operation, since the base does not participate in the picking and placing operation, the operator does not need to carry the base, and the physical consumption can also be greatly reduced; because the sputtered rosin and tin beads during the soldering operation often adhere to the positioning plate, the upper and lower separable positioning plate can be easily immersed in the washing board water to remove the attached rosin and tin beads, which is convenient for cleaning and maintaining the positioning plate, thereby prolonging the service life of the tooling.

[0007] In some embodiments, the alignment pin is in interference fit with the base.

[0008] Adopting the above technical solution, when the alignment pin and the base are of a split structure, the alignment pin can be forcibly pressed into the reserved hole of the positioning pin of the base through interference fit, ensuring its perpendicularity, firmness and reliability.

[0009] In some embodiments, the diameter of the part of the alignment pin protruding from the base gradually decreases from the end close to the base to the end close to the positioning plate, and the diameter of the alignment hole gradually decreases from the end close to the base to the end far from the base.

[0010] Adopting the above technical solution, the conical surface fit can facilitate the introduction when the alignment pin and the alignment hole are inserted into each other, reducing the difficulty of inserting the alignment pin and the alignment hole into each other.

[0011] In some embodiments, the alignment hole is a through hole.

[0012] Adopting the above technical solution, setting the alignment hole as a through hole can, on the one hand, facilitate processing, and on the other hand, can discharge air when the alignment pin and the alignment hole are inserted into each other, preventing the alignment pin and the alignment hole from not being properly fitted due to trapped air.

[0013] In some embodiments, a part of the positioning plate protrudes from the base.

[0014] Adopting the above technical solution, the part of the positioning plate protruding from the base can gain leverage when the positioning plate and the base are separated, facilitating the separation of the positioning plate and the base.

[0015] In some embodiments, the base is provided with an avoidance groove corresponding to the positioning plate, and the avoidance groove communicates with the positioning groove.

[0016] Adopting the above technical solution, setting the avoidance groove can ensure that the wire is properly fitted with the circuit board.

[0017] In some embodiments, a first magnetic member is provided on the base, and a second magnetic member corresponding to the first magnetic member is provided on the positioning plate, and the first magnetic member and the second magnetic member are magnetically attracted to each other.

[0018] With the above technical solution, through the cooperation of the first magnetic member and the second magnetic member, the reliability of the fit between the positioning plate and the base can be improved, and the situation that the positioning plate and the base do not fit properly and affect the welding accuracy can be avoided.

[0019] In some embodiments, an exhaust groove is provided at the edge of the alignment hole.

[0020] With the above technical solution, the exhaust groove is used to discharge the air in the alignment hole when the alignment pin is inserted into the alignment hole, so as to avoid the interference of trapped air on the fit between the alignment pin and the alignment hole.

[0021] In some embodiments, a discharge groove is provided on the base, the discharge groove communicates with the positioning groove and the outside, and the depth of the discharge groove is greater than the depth of the positioning groove.

[0022] With the above technical solution, by providing the discharge groove, it is convenient to take out the circuit board from the positioning groove.

[0023] In some embodiments, the depth of the positioning groove is greater than or equal to the thickness of the circuit board.

[0024] With the above technical solution, the circuit board can be protected and the circuit board can be prevented from colliding. Description of the Drawings

[0033] Please refer to Figures 1 to 4 , which is a convenient wire-clamping and quick-positioning wire-welding tooling 100 according to a preferred embodiment of the present invention, including a base 10 and a positioning plate 20 detachably connected to the base 10. A positioning groove 11 for placing a circuit board is provided on the base 10, and the shape of the positioning groove 11 matches the shape of the circuit board. A plurality of clamping grooves 21 for clamping wires are provided at intervals on the side of the positioning plate 20 opposite to the positioning groove 11. A positioning pin 12 is also provided on the base 10, and a positioning hole 22 corresponding to the positioning pin 12 is provided on the positioning plate 20. The convenient wire-clamping and quick-positioning wire-welding tooling 100 of the present application has the characteristics of simple structure, convenient operation and high working efficiency.

[0034] Similarly, the shape and size of the clamping groove 21 match the shape and size of the wire, and the layout of the clamping grooves 21 on the positioning plate 20 can also be set according to actual needs.

[0035] In this embodiment, the alignment pin 12 and the base 10 are of a split structure; further, the alignment pin 12 and the base 10 are in interference fit. When the alignment pin 12 and the base 10 are of a split structure, the alignment pin 12 can be forced into the pre - reserved hole of the positioning pin of the base 10 by interference fit, ensuring its perpendicularity, firmness and reliability. Optionally, the number and the positions of the alignment pins 12 provided on the base 10 can be set according to actual requirements, and the alignment holes 22 correspond to the alignment pins 12 one by one.

[0036] In other embodiments, the alignment pin 12 and the base 10 can also be integrally formed.

[0037] Preferably, the diameter of the part of the alignment pin 12 protruding from the base 10 gradually decreases from the end close to the base 10 to the end close to the positioning plate 20, and the diameter of the alignment hole 22 gradually decreases from the end close to the base 10 to the end far from the base 10. The tapered surface fit can facilitate the insertion when the alignment pin 12 and the alignment hole 22 are inserted into each other, reduce the difficulty of inserting the alignment pin 12 and the alignment hole 22 into each other, and at the same time can reduce the wear of the alignment pin 12 and the alignment hole 22, extend the service life and improve the fitting accuracy.

[0038] In this embodiment, the alignment hole 22 is a through - hole. Setting the alignment hole 22 as a through - hole can, on the one hand, facilitate processing, and on the other hand, can discharge air when the alignment pin 12 and the alignment hole 22 are inserted into each other, preventing the alignment pin 12 and the alignment hole 22 from being misaligned due to trapped air. To solve the problem of air exhaust, in other embodiments, an exhaust groove can also be provided at the edge of the alignment hole 22. By providing the exhaust groove, the problem of trapped air in the alignment hole 22 can also be solved.

[0039] As Figure 1 shown, in this embodiment, a part of the positioning plate 20 protrudes from the base 10. The part of the positioning plate 20 protruding from the base 10 gains leverage when the positioning plate 20 and the base 10 are separated, facilitating the separation of the positioning plate 20 and the base 10. In other embodiments, a handle can also be provided on the positioning plate 20 to facilitate the movement of the positioning plate 20.

[0040] When the circuit board is placed in the positioning groove 11 and the surface of the circuit board is lower than the surface of the base 10, in order to ensure that the wire is properly fitted with the circuit board, an avoidance groove 13 corresponding to the positioning plate 20 is provided on the base 10, and the avoidance groove 13 communicates with the positioning groove 11.

[0041] Preferably, a first magnetic member 14 is provided on the base 10, and a second magnetic member 23 corresponding to the first magnetic member 14 is provided on the positioning plate 20. The first magnetic member 14 and the second magnetic member 23 are magnetically attracted to each other. By the cooperation of the first magnetic member 14 and the second magnetic member 23, the reliability of the fit between the positioning plate 20 and the base 10 can be improved, and the situation that the positioning plate 20 and the base 10 are not properly fitted and affect the welding accuracy can be avoided. Optionally, both the first magnetic member 14 and the second magnetic member 23 can be magnets, or one of the first magnetic member 14 and the second magnetic member 23 can be set as a magnet, and the other can be set as a magnet that can be attracted by the magnet. The setting position of the number of the first magnetic members 14 can be set according to the actual situation, and is not limited to the structure shown in the drawings. The second magnetic members 23 correspond to the first magnetic members 14 one by one.

[0042] Furthermore, in order to avoid interference between the first magnetic member 14 and the second magnetic member 23 in the fit between the positioning plate 20 and the base 10, the top of the first magnetic member 14 should be slightly lower than its mounting plane. Similarly, the top of the second magnetic member 23 should also be slightly lower than its mounting plane.

[0043] In order to facilitate the removal of the circuit board from the positioning groove 11, a discharge groove 15 is provided on the base 10. The discharge groove 15 communicates with the positioning groove 11 and the outside, and the depth of the discharge groove 15 is greater than the depth of the positioning groove 11.

[0044] Preferably, the depth of the positioning groove 11 is greater than or equal to the thickness of the circuit board. In this way, the circuit board can be sunk into the positioning groove 11, so that the four sides and the bottom of the circuit board are fully protected, and the circuit board can be prevented from colliding.

[0045] During welding, first install the base 10 on the workbench of the automatic welding machine, then place the welding surface of the circuit board upward in the positioning groove 11, and then sequentially clamp the wires in the card slots 21 on the positioning plate 20. In order to improve the efficiency, multiple positioning plates 20 can be equipped and the wires can be respectively clamped. Then, press the side of the positioning plate 20 with the clamped wires downward against the base 10, and make the alignment pins 12 correspond to the alignment holes 22 one by one, and then press the positioning plate 20 in place. After welding is completed, first remove the positioning plate 20, then take out the welded circuit board, and then repeat the above actions (when producing the same product, the base 10 does not need to be repeatedly disassembled and assembled) for continuous welding operations.

[0046] The convenient wire clamping and rapid positioning wire welding tooling 100 of the utility model sets the base 10 and the positioning plate 20 as a separable structure, so that each base 10 can correspond to multiple positioning plates 20. In some cases, when changing different production products, only the positioning plate 20 needs to be replaced, and there is no need to replace the base 10, which can effectively reduce the manufacturing cost of the tooling. At the same time, multiple positioning plates 20 can clamp wires simultaneously, which can improve the flow rate of the welding operation, ensure that the automatic soldering machine operates without interruption, and maximize the efficiency of the equipment; the separable base 10 can be directly fixed on the working slider of the automatic soldering machine, reducing the positioning error caused by repeated picking and placing of the tooling. In each wire welding operation, since the base 10 does not participate in the picking and placing operation, the operator does not need to carry the base 10, and the physical consumption can also be greatly reduced; because the sputtered rosin and tin beads during the soldering operation often adhere to the positioning plate 20, the upper and lower separable positioning plate 20 can be easily immersed in the circuit board cleaning solution to remove the attached rosin and tin beads, which is convenient for cleaning and maintaining the positioning plate 20, thereby prolonging the service life of the tooling.

[0047] Finally, it should be noted that the above are only the preferred examples of the utility model and are not used to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the utility model shall be included within the protection scope of the utility model.
