Description

Technical Field

[0001] The utility model relates to the field of wave soldering, in particular to a wave soldering device. Background Art

[0002] Wave soldering is to make the soldering surface of the plug-in board directly contact with high-temperature liquid tin to achieve the purpose of soldering. The high-temperature liquid tin maintains an inclined surface, and a special device is used to make the liquid tin form a wave-like phenomenon, so it is called "wave soldering". Its main material is solder bar. Wave soldering is an important link in the circuit board production process, and the wave soldering jig used in the wave soldering process is generally a special jig.

[0003] After massive searches, it was found that the Chinese patent with the prior art publication number CN211135849U disclosed a wave soldering device. The patent has movable long and short pressure strips, and the fixture seat can accommodate rectangular PCB boards of different sizes. It has good versatility, saves the number of wave soldering fixtures, and is easy to manage. The hemispherical block is in contact with the X-axis slideway, and the two are in approximate point contact, with small friction resistance. The hemispherical block makes the pulley "suspended", thereby avoiding direct contact between the pulley and the X-axis slideway, reducing the friction resistance between the pulley and the X-axis slideway, and making the pulley roll more smoothly in the X-axis slideway. However, in this patent, since the circuit board is relatively fragile, and the long and short pressure strips are not elastic when pressing the circuit board, the long and short pressure strips may damage the circuit board, affecting the subsequent wave soldering of the circuit board by the staff. Therefore, based on the above search and combined with the prior art, a wave soldering device is proposed to solve the above problems. Utility Model Content

[0022] Example 1: Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 A wave soldering device comprises a jig seat 1, a storage groove 2 for accommodating a circuit board is provided on the top surface of the jig seat 1, the depth of the storage groove 2 is less than the thickness of the circuit board, a supporting groove 3 is provided on the top surface of the storage groove 2, a mounting frame 14 is fixedly installed on the top surface of the jig seat 1, an anti-loosening component 4 for preventing the circuit board from loosening is provided on the top surface of the jig seat 1, and an adapting component 5 for adapting to circuit boards of different widths is provided on the inner bottom surface of the supporting groove 3;

[0023] The anti-loosening component 4 includes a rubber plate 33, which is arranged on the top surface of the jig seat 1, and a movable support bar 13 is installed on the inner top surface of the mounting frame 14. The top surface of the support bar 13 is movably sleeved with a mounting rod 19, and a connecting hole 18 is opened on the top surface of the support bar 13. The outer circular wall surface of the mounting rod 19 is movably sleeved with the inner circular wall surface of the connecting hole 18, and the bottom surface of the mounting rod 19 is fixedly connected to the top surface of the rubber plate 33. The outer circular wall surface of the mounting rod 19 is rotatably connected to two support seats 21, and a plurality of fixed blocks 20 are fixedly installed on the outer circular wall surface of the mounting rod 19. Two first rotating shafts 22 are fixedly installed on the outer circular wall surface of the support seat 21, and the first rotating shaft 22 is rotatably connected to the fixed block 20. A support tube 23 is fixedly installed on one end of the support seat 21, and a connecting rod 24 is elastically connected to the inner circular wall surface of the support tube 23. A spring 34 is sleeved on the outer circular wall surface of the support tube 23, and one end of the spring 34 is fixed to one end of the support seat 21 The fixing connection is that the other end of the spring 34 is fixedly connected to one end of the connecting rod 24, and the connecting rod 24 is rotatably connected to the support bar 13. A plurality of positioning blocks 25 are fixedly installed on the top surface of the support bar 13. Two second rotating shafts 26 are fixedly installed on the outer circular wall surface of the connecting rod 24. The connecting rod 24 is rotatably connected to the two positioning blocks 25 through the second rotating shaft 26. The outer circular wall surface of the mounting rod 19 is provided with an anti-twist member for twisting the mounting rod 19. The anti-twist member includes two limit strips 28. The two limit strips 28 are fixedly installed on the outer circular wall surface of the mounting rod 19. Two positioning holes 27 are provided on the inner circular wall surface of the connecting hole 18. The limit strip 28 is slidably connected to the positioning hole 27. Through the setting of the mounting rod 19, the movement of the mounting rod 19 inside the connecting hole 18 on the support bar 13 drives the limit strip 28 to move inside the positioning hole 27. The limit strip 28 can limit the movement of the mounting rod 19 to prevent the mounting rod 19 from twisting.

[0024] Through the set jig seat 1, the staff places the circuit board inside the storage slot 2 on the jig seat 1, and the staff moves the support bar 13 downward, and the support bar 13 moves downward until the rubber plate 33 on the mounting rod 19 abuts against the top surface of the circuit board. At this time, the rubber plate 33 is squeezed by the circuit board and moves upward inside the connecting hole 18 on the support bar 13. The mounting rod 19 moves upward to drive the support seat 21 and the support cylinder 23 to move upward, and at the same time, the support seat 21 drives the first rotating shaft 22 to rotate on the fixed block 20, and the support cylinder 23 moves outward. The support tube 23 moves outward along the connecting rod 24, and the spring 34 is stretched at the same time. The outward movement of the support tube 23 also causes the mounting rod 19 to drive the second rotating shaft 26 to rotate on the positioning block 25, so that the mounting rod 19 and the limiting rod 30 have elasticity, thereby preventing the circuit board from being damaged due to the abutment of the rubber plate 33. The spring 34 also allows the rubber plate 33 to press the circuit board tightly, thereby preventing the circuit board from loosening during the wave soldering process and preventing the circuit board from being damaged, thereby achieving an anti-loosening effect on the circuit board, which is convenient for the staff to perform wave soldering on the circuit board;

[0026] By setting the threaded rod 15, the staff rotates the threaded rod 15 to drive the inner ring of the bearing 32 to rotate while the support bar 13 does not rotate. The rotation of the threaded rod 15 also causes the threaded rod 15 to drive the support bar 13 and the rubber plate 33 to move downward, thereby realizing the movement of the support bar 13.

[0027] Example 2: Please refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 A wave soldering device, a limit plate 16 is fixedly installed on the bottom surface of the support bar 13, a limit frame 17 is fixedly installed on one side of the jig seat 1, the limit plate 16 is slidably connected with the limit frame 17, through the support bar 13, the support bar 13 moves downward to drive the limit plate 16 to move downward inside the limit frame 17 on the side of the jig seat 1, the limit plate 16 can limit the movement of the support bar 13, so as to achieve the limiting effect of the support bar 13;

[0028] The adaptation component 5 includes a gear 8, which is rotatably connected to the inner bottom surface of the support groove 3. A driving motor 12 for driving the gear 8 to rotate is fixedly installed on the bottom surface of the jig seat 1.

The limiting blocks 31 and the limiting rods 30 can limit the movement of the tooth plate 9, thereby achieving a limiting effect on the tooth plate 9.

[0029] By setting a driving motor 12, the driving shaft of the driving motor 12 rotates to drive the gear 8 to rotate, and the rotation of the gear 8 drives the two tooth plates 9 to move inward, and the inward movement of the tooth plates 9 drives the pressing plate 10 to move inward along the two supporting rods 11 inside the supporting groove 3.
