Description

Technical Field

[0001] The invention relates to processing equipment, in particular to a motor lead shearing and tinning machine. Background Art

[0002] During the production of motors, multiple process steps are required. For example, workers cut the leads on the motors and then transfer them to the tinning machine to manually tin the leads. During this process, the workers' operation is labor-intensive and the work efficiency is low. In order to improve production efficiency, some automatic tinning equipment has emerged to reduce the workers' workload. However, the workers' cutting rhythm of the motor leads and the rhythm of the automatic tinning of the leads by the machine are not unified and difficult to coordinate. In addition, the workpieces also need to be transferred to different workstations, and the overall production efficiency is always difficult to improve. Summary of the Invention

[0003] The object of the present invention is to provide a motor lead shearing and tinning machine to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0004] The solution of the present invention to solve its technical problems is:

[0005] A motor lead shearing and tinning machine comprises: a conveying device having a conveying surface extending in a straight direction, a material stopper being provided on the conveying device on the downstream side of the conveying surface; a shearing assembly connected to the conveying device, an openable and closable shearing opening formed in the shearing assembly, the height of the shearing opening being higher than the height of the conveying surface, and the shearing opening being toward the upstream side of the conveying surface; a tin furnace having a cavity with an upward opening therein; a feeding device having a transfer surface extending in a straight direction; a transfer assembly having a transfer end movable between the conveying surface, the cavity and the transfer surface.

[0006] This technical solution has at least the following beneficial effects: the conveying device has a conveying surface for conveying materials in a straight line direction, and the motor to be cut is placed on the conveying surface. At this time, the lead to be cut on the motor protrudes outward from the conveying surface, and the motor is conveyed toward the shearing component under the drive of the conveying surface. When the motor reaches the blocking member, the blocking member limits the continued movement of the motor, and the lead to be cut enters the shearing opening. At this time, the shearing component closes the shearing opening, and the leads on one or more motors can be cut, and then the shearing opening is reopened to prepare for the next wire cutting. The transfer end in the transfer component first moves to the conveying surface, takes the motor out of the conveying surface after the wire cutting is completed, and then transfers it to the cavity. The cavity is filled with tin solution. After the motor transferred to the cavity is tin-immersed, it is transferred to the transfer surface of the unloading device, and the motor after the tin-immersion is completed is arranged and unloaded by the transfer surface. In this way, the wire cutting process can be completed directly during the motor loading process, and then the motor is directly transferred to complete the tin-immersion process, reducing the transfer of the motor between different equipment, better coordinating the production rhythm, and improving the production efficiency of the motor.

[0007] As a further improvement of the above technical solution, the shearing assembly includes a cutter seat, a swinging drive member, a fixed cutter and a movable cutter, the cutter seat and the swinging drive member are both connected to one side of the conveying device, with the side of the cutter seat away from the conveying device as the outer side, the fixed cutter is connected to the cutter seat, the outer side of the fixed cutter is flush with the outer side of the cutter seat, the movable cutter is rotatably connected to the cutter seat, the inner side of the movable cutter is flush with the outer side of the cutter seat, the shear cut is formed between the movable cutter and the fixed cutter, the swinging drive member drives the movable cutter to be connected, and the swinging drive member can drive the movable cutter to swing back and forth and open or close the shear cut. The movable cutter and the fixed cutter are close to each other, and a shearing notch is formed between them. When the lead enters the shearing notch, the swing driving member drives the movable cutter to swing on the cutter seat, and the mutual misalignment of the movable cutter and the fixed cutter is utilized to cut the lead. At this time, the shearing notch is closed. When the swing driving member drives the movable cutter to swing in the opposite direction on the cutter seat, the shearing notch is opened.

[0008] As a further improvement to the above technical solution, the swing drive member is a telescopic cylinder, the movable cutter includes a transmission section and a shearing section connected to each other, a shearing shaft is inserted in the middle of the shearing section, the shearing shaft is connected to the cutter seat, the fixed end of the telescopic cylinder is rotatably connected to one side of the conveying device, and the movable end of the telescopic cylinder is rotatably connected to the transmission section. The rotation axis of the fixed end of the telescopic cylinder and the rotation axis of the movable end of the telescopic cylinder are both parallel to the length extension direction of the shearing shaft, and the shearing section and the fixed cutter form the shearing section. The shearing shaft passes through the shearing section, and the shearing section can rotate around the shearing shaft. The transmission section increases the distance between the force application point of the telescopic cylinder and the rotation center of the shearing section, and can change the direction of the force, forming a force-saving lever. The telescopic movement of the telescopic cylinder can drive the shearing section to swing back and forth, thereby opening or closing the shearing section.

[0009] As a further improvement to the above technical solution, a locking nut is threadedly connected to the shear shaft, and a compression spring is sleeved on the shear shaft, with its ends respectively abutting against the locking nut and the shearing section. The compression spring presses the shearing section against the cutter seat, thereby better aligning the inner side of the cutter with the outer side of the cutter seat. By adjusting the tightening degree of the locking nut, the compression force of the compression spring on the shearing section can be further adjusted, making adjustment easier and more flexible.

[0010] As a further improvement of the above technical solution, the transfer assembly includes a movable device, a transfer seat, a first lifting drive member, a positioning mold and a permanent magnet. The transfer seat is connected to the movable device, and the movable device can drive the transfer seat to move between the conveying surface, the cavity and the transfer surface. The positioning mold is connected to the bottom side of the transfer seat, and a positioning groove is provided on the bottom side of the positioning mold. The positioning mold has a hollow hole that is interconnected with the positioning mold. The first lifting drive member is connected to the top side of the transfer seat. The first lifting drive member has a lifting end that can move up and down, and the lifting end passes through the transfer seat and extends into the hollow hole. The permanent magnet is connected to the lifting end, and the lifting end can drive the permanent magnet to move back and forth between the hollow hole and the positioning groove. The bottom end of the permanent magnet is the transfer end. When the motor needs to be transferred, the movable device drives the positioning mold to the conveying surface through the transfer seat, so that the motor enters the positioning groove, thereby pre-positioning the motor to be transferred, and then the lifting end moves downward, driving the permanent magnet from the hollow hole into the positioning groove. The permanent magnet's magnetic attraction to the motor is enhanced, so that the motor is relatively fixed in the positioning groove. When the motor needs to be lowered, the movable device drives the positioning mold to the transfer surface through the transfer seat, and then the lifting end moves upward, driving the permanent magnet from the positioning groove into the hollow hole. The magnetic attraction of the permanent magnet to the motor is reduced, and the motor's own gravity is greater than the magnetic attraction of the permanent magnet to the motor, so that the motor falls on the transfer surface. In this way, the motor can be stably transferred, and there is no need to clamp the motor, which reduces the positioning accuracy required for the motor when clamping the motor.

[0011] As a further improvement to the above technical solution, the bottom side of the positioning mold is provided with a plurality of positioning grooves along the conveying direction of the conveying surface, the lifting end is connected to a plurality of permanent magnets, and the plurality of permanent magnets are one-to-one opposite to the plurality of positioning grooves, and the positioning mold is connected to a spring pressure pin on the downstream side of the conveying surface, the bottom end of the spring pressure pin protrudes downward from the positioning mold, and the spring pressure pin can produce elastic deformation in the up and down directions. The bottom side of the positioning mold has a plurality of positioning grooves, which can simultaneously position a plurality of motors, and the lifting end can simultaneously drive a plurality of permanent magnets into the positioning grooves, thereby positioning a plurality of motors respectively, and the spring pressure pin located on the downstream side of the positioning mold near the conveying surface can press against the motor located next to the positioning mold, and when the positioning mold moves down to the conveying surface, the spring pressure pin is in a compressed state, and when the positioning mold moves up, the spring pressure pin can always press the motor against the conveying surface, thereby avoiding pulling up the motor located next to the positioning mold.

[0012] As a further improvement of the above technical solution, the movable device includes a base, a first translation drive member, a second lifting drive member and a rotation drive member. The first translation drive member is connected to the base, the second lifting drive member is connected to the first translation drive member, the first translation drive member can drive the second lifting drive member to move linearly in the horizontal direction, the rotation drive member is connected to the second lifting drive member, the second lifting drive member can drive the rotation drive member to move up and down, the transfer seat is connected to the rotation drive member, the rotation drive member can drive the transfer seat to rotate, and the rotation axis of the transfer seat extends in the horizontal direction. The first translation drive member and the second lifting drive member can drive the transfer seat to move in translation and up and down, so that the positioning mold is transferred to the conveying surface, cavity and transfer surface. During the process of the transfer seat being transferred from the transfer surface to the cavity, the rotary drive member can drive the transfer seat to rotate, so that the posture of the transferred motor is changed, and the lead wire can enter the cavity to realize tin immersion. After the tin immersion is completed, during the process of the transfer seat being transferred from the cavity to the transfer surface, the rotary drive member can drive the transfer seat to rotate and reset, so that the motor returns to its original position.

[0013] As a further improvement to the above technical solution, a second translation drive is provided on the side of the tin furnace, and a third lifting drive is connected to the second translation drive. The second translation drive can drive the third lifting drive to move linearly in the horizontal direction. The third lifting drive is connected to a connecting block, and the connecting block is connected to a lever extending in the horizontal direction. The lever is connected to a tin scraper. The third lifting drive can drive the connecting block to move up and down and make the tin scraper enter the cavity downward or exit the cavity upward. After a long period of tin immersion operation, the tin scraper surface in the cavity has an uneven height. At this time, the second translation drive and the third lifting drive drive drive the lever downward through the connecting block, so that the tin scraper is inserted into the tin scraper surface, and then reciprocates in the horizontal direction to level the tin scraper surface. The second translation drive then drives the tin scraper to move upward and reset.

[0014] As a further improvement to the above technical solution, a mounting hole is provided on one side of the connecting block, into which one end of the lever is inserted. A locking bolt is cooperatingly connected to the connecting block, one end of which extends into the mounting hole and presses against the lever. When the height of the tin scraper inserted into the cavity needs to be adjusted, the locking bolt is loosened, the lever is rotated, and the tilt angle of the tin scraper is changed to adjust the height of the tin scraper inserted into the cavity. Finally, the locking bolt is tightened to secure the lever in the mounting hole.

[0015] As a further improvement of the above technical solution, the conveying device and the unloading device are both belt conveyors. That is, the conveying belts on the two belt conveyors form a conveying surface and a transfer surface respectively, providing a driving force for the motor to move along the straight direction.

DETAILED DESCRIPTION

[0022] The following will clearly and completely describe the concept, specific structure and technical effects of the present invention in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention. In addition, all the connection relationships mentioned in the text do not refer to the direct connection of components, but refer to the fact that a better connection structure can be formed by adding or reducing connecting accessories according to the specific implementation situation. The various technical features in the invention can be combined interactively without conflicting with each other.

[0023] Reference Figure 1, a motor lead shearing and tinning machine, comprising: a conveying device 1, which has a conveying surface 11 extending in a straight direction, and a material stopper 12 is provided on the conveying device 1 on the downstream side of the conveying surface 11; a shearing component 2, which is connected to the conveying device 1, and a shearing opening that can be opened and closed is formed in the shearing component 2, the height of the shearing opening is higher than the height of the conveying surface 11, and the shearing opening is toward the upstream side of the conveying surface 11; a tin furnace 3, which has a cavity 31 with an upward opening inside; a unloading device 4, which has a transfer surface 41 extending in a straight direction; a transfer component 5, which has a transfer end that can move between the conveying surface 11, the cavity 31 and the transfer surface 41.

[0024] As can be seen from the above, the conveying device 1 has a conveying surface 11 for conveying materials in a straight line direction. The motor to be cut is placed on the conveying surface 11. At this time, the lead to be cut on the motor protrudes outward from the conveying surface 11. The motor is driven by the conveying surface 11 to be conveyed in the direction of the shearing component 2. When the motor reaches the blocking member 12, the blocking member 12 limits the continued movement of the motor, and the lead to be cut enters the shearing opening. At this time, the shearing component 2 closes the shearing opening and can cut the lead on one or more motors. Then, the shearing opening is reopened to prepare for the next shearing and the transfer component The transfer end in 5 first moves to the conveying surface 11, takes the motor after the wire trimming is completed out of the conveying surface 11, and then transfers it to the cavity 31. The cavity 31 is filled with tin solution. After the motor is transferred to the cavity 31, it is tin-immersed and then transferred to the transfer surface 41 of the unloading device 4. The transfer surface 41 arranges and unloads the motors after the tin immersion is completed. In this way, the wire trimming process can be completed directly during the motor loading process, and then the motor is directly transferred to complete the tin immersion process, which reduces the transfer of the motor between different equipment, can better coordinate the production rhythm, and improve the production efficiency of the motor.

[0025] The shearing component 2 mainly forms an openable shearing opening to shear the leads on one or more motors, such as Figure 2As shown, in this embodiment, the shearing assembly 2 includes a cutter seat 21, a swinging drive member 22, a fixed cutter 23 and a movable cutter, the cutter seat 21 and the swinging drive member 22 are both connected to one side of the conveying device 1, with the side of the cutter seat 21 away from the conveying device 1 as the outer side, the fixed cutter 23 is connected to the cutter seat 21, the outer side of the fixed cutter 23 is flush with the outer side of the cutter seat 21, the movable cutter is rotatably connected to the cutter seat 21, the inner side of the movable cutter is flush with the outer side of the cutter seat 21, the shearing opening is formed between the movable cutter and the fixed cutter 23, the swinging drive member 22 drives the connected movable cutter, and the swinging drive member 22 can drive the movable cutter to swing back and forth and open or close the shearing opening. The movable cutter and the fixed cutter 23 are close to each other, and a shearing notch is formed between them. When the lead enters the shearing notch, the swing driving member 22 drives the movable cutter to swing on the cutter seat 21, and the mutual misalignment of the movable cutter and the fixed cutter 23 is utilized to cut and cut the lead. At this time, the shearing notch is closed. When the swing driving member drives the movable cutter to swing in the opposite direction on the cutter seat 21, the shearing notch is opened.

[0026] In the above embodiment, the swing driving member 22 can be a driving source that can directly provide a rotational driving force, and in this embodiment, the swing driving member 22 is a telescopic cylinder, and the movable cutter includes a transmission section 241 and a shearing section 242 that are connected to each other. A shearing shaft is inserted in the middle of the shearing section 242, and the shearing shaft is connected to the cutter seat 21. The fixed end of the telescopic cylinder is rotatably connected to one side of the conveying device 1, and the movable end of the telescopic cylinder is rotatably connected to the transmission section 241. The rotation axis of the fixed end of the telescopic cylinder and the rotation axis of the movable end of the telescopic cylinder are both parallel to the length extension direction of the shearing shaft, and the shearing opening is formed between the shearing section 242 and the fixed cutter 23. The shear shaft passes through the shear section 242, and the shear section 242 can rotate around the shear shaft. The transmission section 241 increases the distance between the force application point of the telescopic cylinder and the rotation center of the shear section 242, and can change the direction of the force to form a labor-saving lever. The shear section 242 can be driven to swing back and forth through the telescopic activity of the telescopic cylinder, thereby opening or closing the shear opening.

[0027] In the above embodiment, the shearing section 242 is rotatably connected to the shearing shaft by limiting the position of the shearing section 242 through a bearing or an annular groove. During the process of shearing the lead wire by utilizing the offset between the shearing section 242 and the fixed cutter 23, the shearing section 242 is constantly subjected to an outward thrust. To further enhance the stability of the shearing section 242 and improve the quality of the lead wire shearing, in this embodiment, a locking nut 25 is threadedly connected to the shearing shaft. A compression spring 26 is sleeved on the shearing shaft, with its ends respectively abutting against the locking nut 25 and the shearing section 242. The compression spring 26 presses the shearing section 242 against the cutter seat 21, thereby better aligning the inner side of the cutter with the outer side of the cutter seat 21. By adjusting the tightening degree of the locking nut 25, the pressing force of the compression spring 26 on the shearing section 242 can be further adjusted, thereby facilitating adjustment and providing greater flexibility.

[0028] The transfer assembly 5 is mainly used to grab the motor on the conveying surface 11 and drive the motor to move between the conveying surface 11, the cavity 31 and the transfer surface 41. Figure 4As shown, in this embodiment, the transfer assembly 5 includes a movable device, a transfer seat 51, a first lifting drive member 52, a positioning mold 53 and a permanent magnet 54. The transfer seat 51 is connected to the movable device, and the movable device can drive the transfer seat 51 to move between the conveying surface 11, the cavity 31 and the transfer surface 41. The positioning mold 53 is connected to the bottom side of the transfer seat 51, and a positioning groove 531 is provided on the bottom side of the positioning mold 53. The positioning mold 53 has a hollow hole that is interconnected with the positioning mold 53. The first lifting drive member 52 is connected to the top side of the transfer seat 51. The first lifting drive member 52 has a lifting end that can move up and down. The lifting end passes through the transfer seat 51 and extends into the hollow hole. The permanent magnet 54 is connected to the lifting end. The lifting end can drive the permanent magnet 54 to move back and forth between the hollow hole and the positioning groove 531. The bottom end of the permanent magnet 54 is the transfer end. When the motor needs to be transferred, the movable device drives the positioning mold 53 to move to the conveying surface 11 through the transfer seat 51, so that the motor enters the positioning groove 531, thereby pre-positioning the motor to be transferred, and then the lifting end moves downward, driving the permanent magnet 54 to enter the positioning groove 531 from the hollow hole. The magnetic attraction of the permanent magnet 54 to the motor is enhanced, so that the motor is relatively fixed in the positioning groove 531. When the motor needs to be lowered, the movable device drives the positioning mold 53 to move to the transfer surface 41 through the transfer seat 51, and then the lifting end moves upward, driving the permanent magnet 54 to enter the hollow hole from the positioning groove 531. The magnetic attraction of the permanent magnet 54 to the motor is reduced, and the motor's own gravity is greater than the magnetic attraction of the permanent magnet 54 to the motor, causing the motor to fall on the transfer surface 41. In this way, the motor can be stably transferred, and there is no need to clamp the motor, thereby reducing the positioning accuracy required for the motor when clamping the motor.

[0029] In order to facilitate the grabbing and transporting of side-by-side motors, in this embodiment, a plurality of positioning grooves 531 are provided on the bottom side of the positioning mold 53 along the conveying direction of the conveying surface 11, and a plurality of permanent magnets 54 are connected to the lifting end, and the plurality of permanent magnets 54 are one-to-one corresponding to the plurality of positioning grooves 531. A spring pressure pin 55 is connected to the downstream side of the conveying of the positioning mold 53 close to the conveying surface 11, and the bottom end of the spring pressure pin 55 protrudes downward from the positioning mold 53, and the spring pressure pin 55 can produce elastic deformation in the up and down directions. The bottom side of the positioning mold 53 has multiple positioning grooves 531, which can position multiple motors at the same time, and the lifting end can simultaneously drive multiple permanent magnets 54 into the positioning grooves 531, thereby positioning multiple motors respectively. The spring pressure pin 55 located on the downstream side of the positioning mold 53 close to the conveying surface 11 can press on the motor located next to the positioning mold 53. When the positioning mold 53 moves down to the conveying surface 11, the spring pressure pin 55 is in a compressed state. When the positioning mold 53 moves up, the spring pressure pin 55 can always press the motor tightly against the conveying surface 11, thereby avoiding that the motor located next to the positioning mold 53 is also pulled up.

[0030] The movable device is mainly used to provide power for movement in two-dimensional or three-dimensional directions, and can directly adopt a driving structure such as a robotic arm. In this embodiment, the movable device includes a base, a first translation drive member 56, a second lifting drive member 57 and a rotation drive member 58. The first translation drive member 56 is connected to the base, and the second lifting drive member 57 is connected to the first translation drive member 56. The first translation drive member 56 can drive the second lifting drive member 57 to move linearly in the horizontal direction. The rotation drive member 58 is connected to the second lifting drive member 57. The second lifting drive member 57 can drive the rotation drive member 58 to move up and down. The transfer seat 51 is connected to the rotation drive member 58. The rotation drive member 58 can drive the transfer seat 51 to rotate, and the rotation axis of the transfer seat 51 extends in the horizontal direction. The first translation drive member 56 and the second lifting drive member 57 can drive the transfer seat 51 to move in translation and up and down, so that the positioning mold 53 is transferred to the conveying surface 11, the cavity 31 and the transfer surface 41. During the process of the transfer seat 51 being transferred from the transfer surface 41 to the cavity 31, the rotating drive member 58 can drive the transfer seat 51 to rotate, so that the posture of the transferred motor is changed, and the lead can enter the cavity 31 to realize tin immersion. After the tin immersion is completed, during the process of the transfer seat 51 being transferred from the cavity 31 to the transfer surface 41, the rotating drive member 58 can drive the transfer seat 51 to rotate and reset, so that the motor returns to its original position.

[0031] In order to improve the effect of tinning the leads, Figure 3As shown, in this embodiment, a second translational drive member 32 is provided on the side of the tin pot 3. A third lifting drive member 33 is connected to the second translational drive member 32. The second translational drive member 32 drives the third lifting drive member 33 to move linearly in the horizontal direction. The third lifting drive member 33 is connected to a connecting block, which is connected to a horizontally extending lever 34. A tin scraper 35 is connected to the lever 34. The third lifting drive member 33 drives the connecting block up and down, causing the tin scraper 35 to enter the cavity 31 downward or exit the cavity 31 upward. After a long period of tinning operation, the tin solution in the cavity 31 has an uneven scraping surface. In this case, the second translational drive member 32 and the third lifting drive member 33 drive the lever 34 downward through the connecting block, allowing the tin scraper 35 to penetrate the scraping surface. The lever 34 is then reciprocated horizontally to level the scraping surface. The second translational drive member 32 then drives the tin scraper 35 upward to reset.

[0032] In actual applications, the first lifting drive member 52, the second lifting drive member 57, the third lifting drive member 33, the first translation drive member 56 and the second translation drive member 32 are all used to provide driving force for linear reciprocating motion, and their structural forms include various types, such as electric push rods, pneumatic push rods or hydraulic push rods.

[0033] To facilitate adjustment of the height at which the tin scraper 35 extends into the cavity 31, in this embodiment, a mounting hole is provided on one side of the connecting block, into which one end of the lever 34 is inserted. A locking bolt 36 is cooperatingly connected to the connecting block, one end of which extends into the mounting hole and presses against the lever 34. To adjust the height at which the tin scraper 35 extends into the cavity 31, the locking bolt 36 is loosened, and the lever 34 is rotated to adjust the inclination angle of the tin scraper 35, thereby adjusting the height at which the tin scraper 35 extends into the cavity 31. Finally, the locking bolt 36 is tightened to secure the lever 34 in the mounting hole.

[0034] In some embodiments, the conveying device 1 and the unloading device 4 are both belt conveyors. Specifically, the conveying belts on the two belt conveyors form a conveying surface 11 and a transfer surface 41, respectively, which provide a driving force for the motor to move the conveyor in a linear direction.
