Description

TECHNICAL FIELD

[0001] The present application relates to a tin dipping device, in particular to a tin dipping device for inductance coils. BACKGROUND

[0002] The inductance coil is an electronic component that works on the principle of electromagnetic induction, which is usually wound by multiple turns of wire, and the wire is coated with an insulating layer. A magnetic field is formed by the current, and when connected with other components, the pin connector of the inductance coil needs to be dipped in tin first, and then connected with other components through welding to ensure the tightness and reliability of the connection. The main function of the tin dipping process is to coat a layer of tin on the metal surface to prevent oxidation and promote welding.

[0003] In the existing tin dipping equipment, a cross beam design is usually adopted, as shown in the patent coil support structure for tin dipping machine (announcement number CN217316297U), which directly mounts multiple inductance coils to be dipped in tin on the cross beam support for batch tin dipping treatment. However, in the actual production process, it is found that this design is more cumbersome to operate when loading coils in batches, and the tin-dipped coils are not easy to take out, so it will also affect the efficiency of batch production. SUMMARY

[0004] In order to solve the above technical problems, the purpose of the present application is to provide a tin dipping device for inductance coils, which solves the problems of complex batch tin dipping operation and inconvenience after tin dipping in the prior art, and through the design of automation, the present application can reduce manual intervention, improve production efficiency, shorten the tin dipping time, and also ensure the stable tin dipping quality of the coil.

[0007] At this point, when the inductor coil needs to be taken out after immersion in tin, only the pulling cylinder located at both ends of the side base plate one and the side base plate two needs to be started, so that the distance between the side base plate one and the side base plate two is expanded, and then the sleeve pressing plate can drive the inductor coil on one side to move towards the end of the core column under the driving of the top spring, until the inductor coil is separated from the core column, at this time the core column can fall to the lower inductor coil device for receiving, so as to improve the efficiency of batch production of products.

[0008] Preferably, the side base plate one is also provided with two groups of sealing plates, which are vertically distributed with the side base plate one, and the sealing plates are also provided with U-shaped grooves for the wire terminals of the inductor coil to pass through;

[0009] The setting of the sealing plate can ensure that the pin wire terminal of the inductor coil will not cause the tin liquid to splash on the inductor coil during immersion in tin, which plays a certain protective effect, and the setting of the two groups of sealing plates can correspond to the situation of the pin wire terminal at both ends.

[0010] Preferably, the end of the guide column is also provided with an end block, and the guide sleeve is also provided with an end groove connected with the end block, so that when the pulling cylinder drives the side base plate two to move away from the side base plate one, even if it is separated from the side base plate one, the sleeve pressing plate can also be ensured not to be separated from the guide column under the pressing of the pressing spring, so as to improve the stability of the tooling.

[0011] Preferably, the outer side of the side base plate one and the side base plate two is also provided with a straight T-shaped guide strip, and the immersion tin device for the inductor coil also comprises a group of rotating column groups, the rotating column groups are uniformly provided with at least two groups of installation grooves along the circumference, and each group of installation grooves is provided with two groups of oppositely arranged T-shaped guide grooves, and the two groups of oppositely arranged T-shaped guide grooves are correspondingly slidably connected with the two groups of T-shaped guide strips of a group of immersion tin positioning tooling;

[0012] At this point, a group of immersion tin positioning tooling can be slid into a group of installation grooves from one end of the rotating column group, and then it can be rotated to the immersion tin station, and when the tin liquid tank is immersed in tin by the top cylinder, the next group of immersion tin positioning tooling can also be loaded at the loading station and unloaded after immersion in tin, so as to achieve higher efficiency of batch production.

[0013] Preferably, the installation slot on the rotating column group is provided with four groups, and the rotating column group is driven to rotate by the rotating motor at one end. When the installation slot rotates to the top end, it is placed in the feeding position. In the feeding position, the T-shaped guide groove is used to accommodate the immersion tin positioning tool pushed into the installation slot. The installation slot is also provided with two groups of limiting cylinders for limiting the two ends of the T-shaped guide bar. When the leading end of the T-shaped guide bar slides to abut against the driving end of one group of limiting cylinders, the driving end of the other group of limiting cylinders is pushed out to abut against the trailing end of the T-shaped guide bar. Thus, the limiting of feeding is completed. After feeding, the immersion tin positioning tool is rotated with the rotating column group to be positioned in the detection position, the immersion tin position, and the discharging position in turn to perform the detection, immersion tin, and discharging operations of the inductor coil.

[0014] Preferably, in the detection position, a detection camera is arranged for taking a picture of the inductor coil to detect whether it is fed. In the immersion tin position, the tin liquid tank is lifted by the top cylinder to immerse the tin liquid into the lead connecting head of the inductor coil. In the discharging position, a discharging push rod is arranged for pushing the immersion tin positioning tool out of the T-shaped guide groove into the discharging guide groove.

[0015] After discharging is completed, the rotating column group is rotated by 90° again to return the empty installation slot to the feeding position. At this time, the immersion tin positioning tool in the feeding guide groove is pushed into the installation slot by the feeding push rod, and one group of limiting cylinders in the installation slot is extended again to limit the immersion tin positioning tool fed by the feeding push rod. In this way, the circulation and reciprocation are completed. The reciprocation at this time is suitable for the case that two groups of lead connecting heads are at one end of the coil.

[0016] Preferably, in the detection position, the operation of feeding with turning over is replaced. In the feeding position, the feeding guide groove is connected with the T-shaped guide groove, and the feeding push rod is used to push the immersion tin positioning tool in the feeding guide groove into the T-shaped guide groove. After the feeding push rod pushes one group of immersion tin positioning tools, the rotating column group is rotated by 90°. After the feeding push rod successively pushes three groups of immersion tin positioning tools, the rotating column group is continuously rotated by 90° so that the feeding guide groove is connected with the T-shaped guide groove. At this time, the feeding push rod is temporarily stopped for feeding. After the feeding is temporarily stopped for three times, the rotating column group is continuously rotated by 90° so that the feeding guide groove is connected with the T-shaped guide groove. At this time, the feeding push rod continues the feeding operation. After the feeding is temporarily stopped in the feeding position, the empty installation slot is rotated to the detection position to perform the operation of feeding with turning over.

[0017] Preferably, in the discharging position, the fixed discharging guide groove is also aligned with the installation slot with one group of movable guide grooves. The movable guide grooves are installed on the driving end of the reciprocating cylinder through a U-shaped support. The reciprocating cylinder is used to drive the movable guide grooves to reciprocate between the detection position and the discharging position. The U-shaped support is also provided with a back-and-forth push rod for pushing the movable guide grooves to move back and forth.

[0018] When the tin immersion positioning tooling belt drives the inductor coil to be pushed into the movable guide groove by the reciprocating push rod for the first time, the reciprocating cylinder drives the movable guide groove to move linearly to the detection station to make the movable guide groove and the mounting groove butt joint, and then the reciprocating push rod pushes the tin immersion positioning tooling in the movable guide groove back to the empty mounting groove at the detection station, and then the reciprocating cylinder drives the movable guide groove to return to the blanking station again, and when the tin immersion positioning tooling belt drives the inductor coil to be pushed into the movable guide groove by the reciprocating push rod for the second time, the blanking push rod continues to push the tin immersion positioning tooling in the movable guide groove into the blanking guide groove.

[0019] That is, after feeding three times in the feeding station, the state that the tin immersion positioning tooling is formed in the detection station, the tin immersion station and the blanking station is formed, at this time, the feeding station is in an empty state, at this time, after the detection, the tin immersion and the blanking operation in the detection station, the tin immersion station and the blanking station are completed, the rotating column group continues to rotate by 90°, and the movable guide groove at the blanking station also linearly returns to the detection station from the first entering tin immersion positioning tooling, at this time, the direction of the pin connector of the inductor coil is reversed, when the reversed inductor coil enters the tin immersion station again by rotating the rotating column group by 90°, the tin immersion of the pin connector on the other side of the inductor coil can be realized, and after the movable guide groove returns to the tin immersion positioning tooling for three times, the tin immersion positioning tooling returned to the tin immersion positioning tooling in the movable guide groove at the blanking station is the tin immersion positioning tooling after the second tin immersion, at this time, the blanking push rod mounted on one side of the blanking guide groove can continue to push the tin immersion positioning tooling in the movable guide groove into the blanking guide groove, and after three times of blanking are completed, the turning feeding operation of the movable guide groove returning to the detection station is continued, at this time, compared with the traditional manual taking out of the inductor coil, the inductor coil is reversed and then continuously immersed, which is more convenient and fast, and the stability of the tin immersion is better.

[0020] The beneficial effects of the present application are: the tin immersion device for the inductor coil provided by the present application solves the problems of complex batch tin immersion operation and inconvenience of taking out after tin immersion in the prior art, and through the automatic design, the present application can reduce manual intervention, improve production efficiency, shorten the tin immersion time, and also ensure the stable tin immersion quality of the coil; specifically, when the inductor coil needs to be taken out after tin immersion, only the cylinder pulling at the left and right ends of the side plate one and the side plate two is started, so that the distance between the side plate one and the side plate two is expanded, and then the sleeve pressing plate can drive the inductor coil on one side to move towards the end of the core column under the driving of the top pressing spring until the inductor coil is separated from the core column, at this time, the core column can fall to the lower part for receiving the inductor coil device, thereby improving the efficiency of batch production of products.

[0021] Meanwhile, the present application can also be compatible with batch tin dipping operation of terminal at one end or both ends; Specifically, by adding rotating column group, it can ensure that a group of tin dipping positioning tooling can be slid into a group of installation slots from one end of the rotating column group, and then can be rotated to the tin dipping station with the rotating column group, and in the tin dipping station, the tin liquid tank can also be able to perform the feeding operation of the next group of tin dipping positioning tooling and the unloading operation after tin dipping when the tin dipping operation is performed by the top cylinder lifting, so as to achieve the operation of more efficient batch production, and after the unloading is completed, the rotating column group is rotated again by 90° to make the empty installation slot return to the feeding station again, at this time the tin dipping positioning tooling is pushed into the installation slot by the feeding push rod in the feeding guide slot, and a group of limiting cylinders in the installation slot are extended again to limit the tin dipping positioning tooling pushed by the feeding push rod for feeding, so as to complete the circulation of reciprocation, at this time the reciprocation is suitable for the situation of two groups of lead terminals on one end of the coil; and for the situation of two groups of lead terminals on both ends of the coil, the detection station is set, and the operation of feeding with turning over is replaced, in the feeding station, after the feeding push rod pushes a group of tin dipping positioning tooling, the rotating column group is rotated by 90°, and after the feeding push rod successively pushes three groups of tin dipping positioning tooling for feeding, the rotating column group is continuously rotated by 90° so that the feeding guide slot is connected with the T-shaped guide slot, the feeding push rod is temporarily stopped for feeding, and after the feeding is stopped for three times, the rotating column group is continuously rotated by 90° so that the feeding guide slot is connected with the T-shaped guide slot, the feeding push rod is continuously fed, and after the feeding is stopped in the feeding station, the empty installation slot is rotated to the detection station to perform the feeding operation with turning over, that is, after feeding for three times in the feeding station, the state that the tin dipping positioning tooling is in the detection station, the tin dipping station and the unloading station is formed, at this time the feeding station is in an empty state, after the detection, tin dipping and unloading operations in the detection station, the tin dipping station and the unloading station are completed, the rotating column group is continuously rotated by 90°, and the movable guide slot in the unloading station also returns the first entering tin dipping positioning tooling to the detection station, at this time the direction of the lead terminal of the inductor coil is reversed, when the reversed inductor coil is rotated by 90° with the rotating column group to enter the tin dipping station, the tin dipping of the lead terminal on the other side of the inductor coil can be realized, and after the movable guide slot successively returns the tin dipping positioning tooling for three times, the tin dipping positioning tooling returned to the detection station by the movable guide slot is the tin dipping positioning tooling after the second tin dipping, at this time, the unloading push rod installed on one side of the unloading guide slot can continue to push the tin dipping positioning tooling in the movable guide slot into the unloading guide slot, and after three times of unloading are completed, the turning over feeding operation of the movable guide slot returning to the detection station is continued, at this time, compared with the traditional manual inductor coil taking out, reversing and continuing tin dipping, it is more convenient and fast, and the tin dipping stability is also better.

[0034] Example 1

[0035] like Figures 1-2 As shown, a tin-dipping device for inductor coils, in this embodiment, includes a tin-dipping positioning fixture 1. The tin-dipping positioning fixture 1 includes a first side substrate 101, a pressure plate 102, and a second side substrate 103 arranged in parallel. The first side substrate 101 has multiple sets of core posts 104 arranged in a straight line. Inductor coils 105 are correspondingly sleeved on the core posts 104. The pressure plate 102 has core holes that guide and fit around the core posts 104. At the four corners of the first side substrate 101, four guide posts 106 arranged in a rectangle are also provided. The pressure plate 102 also has guides that connect with the guide posts 106. The connecting guide hole, and the sleeve plate 102 and the side substrate 1 101 are also provided with four sets of top pressure springs 107 corresponding to the four sets of guide posts 106. The side substrate 2 103 is provided with a guide sleeve 108 connected to the guide post 106. The side substrate 1 101 and the side substrate 2 103 are also driven by a pull cylinder 109. The pull cylinder 109 is used to adjust the distance between the side substrate 1 101 and the side substrate 2 103, and drives the guide sleeve 108 to press the sleeve plate 102 to compress the top pressure springs 107 to limit the inductor coil 105 between the sleeve plate 102 and the side substrate 2 103.

[0036] Therefore, when the inductor coil 105 needs to be removed after tinning, it is only necessary to activate the pull cylinders 109 located at the left and right ends of the side substrate 101 and the side substrate 2 103 to widen the gap between the side substrate 101 and the side substrate 2 103. Then, the pressure plate 102 can push the inductor coil 105 on one side toward the end of the core column 104 under the drive of the top pressure spring 107 until the inductor coil 105 is separated from the core column 104. At this time, the core column 104 can fall below to receive the inductor coil 105, thereby improving the efficiency of mass production.

[0037] The end of the guide post 106 is also provided with an end block 112, and the guide sleeve 108 is also provided with an end groove that is guided and connected to the end block 112. Therefore, when the pull cylinder 109 drives the second side base plate 103 away from the first side base plate 101, even when it is separated from the first side base plate 101, it can be ensured that the pressure plate 102 will not be separated from the guide post 106 under the pressure of the top pressure spring 107, so as to improve the stability of the tooling.

[0038] Example 2

[0039] like Figures 3-4 As shown, a tin-dipping device for an inductor coil is, in this embodiment, a further limitation based on embodiment 1, wherein two sets of sealing plates 110 are also provided on the side substrate 101, the sealing plates 110 are perpendicularly distributed to the side substrate 101, and the sealing plates 110 are also provided with U-shaped grooves 111 through which the terminals of the inductor coil 105 pass.

[0040] The setting of the sealing plate 110 can ensure that the solder will not splash onto the inductor coil 105 when the pin terminals are immersed in solder, thus providing a certain degree of protection. The setting of two sets of sealing plates 110 can correspond to the situation where the pin terminals are at both ends.

[0041] Example 3

[0042] like Figures 5-7 As shown, a tin-dipping device for inductor coils, in this embodiment, is a further limitation based on embodiment 1. Straight T-shaped guide strips 113 are also provided on the outer side of side substrate 101 and side substrate 2 103. The tin-dipping device for inductor coils also includes a set of rotating column groups 2. The rotating column groups 2 are evenly provided with at least two sets of mounting grooves 3 along the circumference. Each set of mounting grooves 3 is provided with two sets of opposing T-shaped guide grooves 4. The two sets of opposing T-shaped guide grooves 4 are slidably connected to the two sets of T-shaped guide strips 113 of a tin-dipping positioning fixture 1.

[0043] This ensures that a set of tin-dipping positioning fixtures 1 can slide into a set of mounting slots 3 from one end of the rotating column group 2, and then rotate with the rotating column group 2 to the tin-dipping station 7. At the tin-dipping station 7, while the solder bath 10 is being lifted by the top cylinder for tin-dipping, the loading operation of the next set of tin-dipping positioning fixtures 1 and the unloading operation after tin-dipping can also be carried out at the loading station 5, thereby achieving more efficient batch production.

[0044] The installation slot 3 on the rotating column group 2 is provided with four groups, and the rotating column group 2 is driven to rotate by the rotating motor located at one end. When the installation slot 3 rotates to the top end, it is placed at the feeding station 5. At the feeding station 5, the T-shaped guide slot 4 is used to accommodate the tin immersion positioning tool 1 pushed into the installation slot 3, and the installation slot 3 is also provided with two groups of limiting cylinders 9 for limiting the two ends of the T-shaped guide strip 113. When the leading end of the T-shaped guide strip 113 slides to abut against the driving end of one group of limiting cylinders 9, the driving end of the other group of limiting cylinders 9 is pushed out to abut against the trailing end of the T-shaped guide strip 113. Thus, the limiting of feeding can be completed, and the tin immersion positioning tool 1 after feeding is rotated with the rotating column group 2 to be positioned in turn at the detection station 6, the tin immersion station 7 and the discharging station 8 for detection, tin immersion and discharging operations of the inductor coil 105.

[0045] At the detection station 6, a detection camera is arranged for taking a picture of the inductor coil 105 to detect whether it is fed. At the tin immersion station 7, the tin liquid tank 10 is lifted by the top cylinder to immerse the tin liquid into the lead connecting piece of the inductor coil 105. At the discharging station 8, a discharging push rod is arranged for pushing the tin immersion positioning tool 1 out of the T-shaped guide slot 4 into the discharging guide slot. The discharging push rod is a push cylinder 151 for linear driving back and forth and a push rod 152 located at the driving end of the push cylinder 151 for lifting operation. The driving directions of the push cylinder 151 and the push rod 152 are vertically arranged. Similarly, the structure of the feeding push rod and the back-and-forth push rod 15 is also the same. Thus, when discharging, the push cylinder 151 can realize linear driving back and forth along the discharging guide slot, and the push rod 152 is used to lift the tin immersion positioning tool 1 to support the pushing force when the tin immersion positioning tool 1 advances, and can be lowered to a low position without interfering with the movement of the tin immersion positioning tool 1 when returning.

[0046] After discharging is completed, the rotating column group 2 is rotated by 90° again to return the empty installation slot 3 to the feeding station 5. At this time, the tin immersion positioning tool 1 is pushed into the installation slot 3 by the feeding push rod in the feeding guide slot 11, and one group of limiting cylinders 9 in the installation slot 3 is extended again to limit the tin immersion positioning tool 1 fed by the feeding push rod. Thus, the circulation is completed. The circulation at this time is suitable for the case that two lead connecting pieces are at one end of the coil.

[0049] In the discharging station 8, the fixed discharging guide groove is also aligned with the mounting groove 3, and a group of movable guide grooves 12 are arranged between the fixed discharging guide groove and the mounting groove 3, the movable guide grooves 12 are installed on the driving end of the reciprocating cylinder 14 through the U-shaped bracket 13, the reciprocating cylinder 14 is used to drive the movable guide grooves 12 to reciprocate between the detection station 6 and the discharging station 8, and the reciprocating push rod 15 for pushing the movable guide grooves 12 to reciprocate is arranged on the U-shaped bracket 13;

[0050] When each group of tin dipping positioning tools 1 drives the inductance coil 105 to be pushed into the movable guide groove 12 by the reciprocating push rod 15 for the first time, the reciprocating cylinder 14 drives the movable guide groove 12 to move linearly to the detection station 6 so that the movable guide groove 12 is connected with the mounting groove 3, then the reciprocating push rod 15 pushes the tin dipping positioning tool 1 in the movable guide groove 12 back to the empty mounting groove 3 in the detection station 6, then the reciprocating cylinder 14 drives the movable guide groove 12 to return to the discharging station 8, and when the group of tin dipping positioning tools 1 drives the inductance coil 105 to be pushed into the movable guide groove 12 by the reciprocating push rod 15 for the second time, the discharging push rod continues to push the tin dipping positioning tool 1 in the movable guide groove 12 into the discharging guide groove; thus, the tin dipping of the two groups of lead wire terminals on both ends of the coil can be completed;

[0051] That is, at the feeding station 5, after feeding three times in succession, the state of the tin immersion positioning tool 1 is formed at the detection station 6, the tin immersion station 7 and the discharging station 8, at this time, the feeding station 5 is in an idle state, at this time, after the detection station 6, the tin immersion station 7 and the discharging station 8 complete the corresponding detection, tin immersion and discharging operation, the rotating column group 2 continues to rotate 90°, and the movable guide groove 12 at the discharging station 8 will also be returned to the detection station 6 along the first entering tin immersion positioning tool 1, at this time, the direction of the pin connection head of the inductor coil 105 is reversed, when the reversed inductor coil 105 enters the tin immersion station 7 again with the rotating column group 2 rotating 90°, the tin immersion of the other side pin connection head of the inductor coil 105 can be realized, and after the movable guide groove 12 returns the tin immersion positioning tool 1 three times in succession, the tin immersion positioning tool 1 returned to the discharging station 8 again is the tin immersion positioning tool 1 after the second tin immersion is completed, at this time, the discharging push rod installed on one side of the discharging guide groove can continue to push the tin immersion positioning tool 1 in the movable guide groove into the discharging guide groove, and after three times of discharging are completed in succession, the turning feeding operation of returning the movable guide groove 12 to the detection station 6 is continued, at this time, compared with the traditional manual taking out of the inductor coil 105, the reversing and continuing tin immersion are more convenient and fast, and the tin immersion stability is also better.

[0053] Meanwhile, the application can also be compatible with batch tin immersion operation of the terminal at one end or both ends. Specifically, by adding the rotating column group 2, it can be ensured that a set of tin immersion positioning tool 1 can be inserted into a set of installation slot 3 from one end of the rotating column group 2, and then it can be rotated to the tin immersion station 7 with the rotating column group 2. In the tin immersion station 7, when the tin liquid tank 10 is lifted by the top cylinder for tin immersion operation, it can also simultaneously perform the feeding operation of the next set of tin immersion positioning tool 1 in the feeding station 5 and the unloading operation after the tin immersion, so as to achieve the operation of more efficient batch production, and after the unloading is completed, the rotating column group 2 is rotated by 90° again to make the empty installation slot 3 return to the feeding station 5 again. At this time, the tin immersion positioning tool 1 is pushed into the installation slot 3 by the feeding push rod in the feeding guide slot 11, and a set of limiting cylinders 9 in the installation slot 3 are extended again to limit the tin immersion positioning tool 1 fed by the feeding push rod, so as to complete the circulation. The circulation at this time is suitable for the situation of two groups of lead terminals at one end of the coil.And for the two groups of lead wire terminals on both ends of the coil, the detection station 6 is provided, and the operation of feeding with turning over is replaced. After the feeding push rod pushes one group of tin immersion positioning tool 1 at the feeding station 5, the rotating column group 2 rotates 90°, and after the feeding push rod successively pushes three groups of tin immersion positioning tool 1, the rotating column group 2 continues to rotate 90° so that the feeding guide groove 11 is connected with the T-shaped guide groove 4, and the feeding push rod is temporarily stopped for feeding. When the feeding guide groove 11 is connected with the T-shaped guide groove 4 after the rotating column group 2 continues to rotate 90° for three times, the feeding push rod continues to feed. After the feeding push rod is temporarily stopped for feeding at the feeding station 5, the empty installation groove 3 is turned over when it rotates to the detection station 6, and the feeding with turning over is performed. That is, after feeding three times at the feeding station 5, the tin immersion positioning tool 1 is formed at the detection station 6, the tin immersion station 7 and the discharging station 8. At this time, the feeding station 5 is in an empty state. After the detection station 6, the tin immersion station 7 and the discharging station 8 complete the corresponding detection, tin immersion and discharging operations, the rotating column group 2 continues to rotate 90°, and the movable guide groove 12 at the discharging station 8 simultaneously returns the first tin immersion positioning tool 1 to the detection station 6. At this time, the direction of the lead wire terminal of the inductor coil 105 is reversed. When the reversed inductor coil 105 enters the tin immersion station 7 again with the rotating column group 2 rotating 90°, the tin immersion of the lead wire terminal on the other side of the inductor coil 105 can be realized. After the movable guide groove 12 successively returns the tin immersion positioning tool 1 three times, the tin immersion positioning tool 1 returned to the discharging station 8 is the tin immersion positioning tool 1 after the second tin immersion. At this time, the discharging push rod installed on one side of the discharging guide groove can continue to push the tin immersion positioning tool 1 in the movable guide groove 12 into the discharging guide groove. After three times of discharging, the feeding with turning over of the movable guide groove 12 to the detection station 6 is continued. Compared with the traditional manual operation of taking out the inductor coil 105, reversing and then continuing to tin immersion, the operation is more convenient and fast, and the tin immersion stability is better.
