Description

Technical Field

[0001] The present invention relates to an assembly device, and particularly to an automatic assembly device for a solder ring heat shrinkable tube. Background Art

[0002] The solder ring heat shrinkable tube, also known as the tin ring wire welding tube, the heat shrinkable tube in the solder joint, the tin ring tube, and the heat shrinkable shielding solder ring. For example Figure 10 , it is composed of a low melting point solder ring a with a hot melt adhesive ring b placed at a certain distance on each of the left and right sides, and then a heat shrinkable tube c is sleeved outside. It can replace the old construction method of soldering with an electric soldering iron, and can not only complete the connection of conductors, but also protect the joints from oxidation by air and other corrosive gases, and prevent the joints from contacting each other. It is widely used in the fields of railways, ships, aerospace, electric power, electronics, etc. It realizes the one-time completion of wire connection, shielding and waterproofing, and is safe and reliable.

[0003] However, for the assembly of the solder ring heat shrinkable tube at present, most of them adopt manual assembly, and the process of loading the solder ring a and the hot melt adhesive rings b on both sides into the heat shrinkable tube c is difficult to operate, and the assembly efficiency is low. Summary of the Invention

[0004] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide an automatic assembly device for a solder ring heat shrinkable tube.

[0005] To achieve the above purpose, the present invention provides the following technical solutions: including a clamping device for assembling and clamping a solder ring and a hot melt adhesive ring on a heat shrinkable tube, a solder ring feeding device for feeding and transporting the solder ring to the clamping device, a hot melt adhesive ring feeding device for feeding and transporting the hot melt adhesive ring to the clamping device, a heat shrinkable tube feeding device for feeding and transporting the heat shrinkable tube to the clamping device, a heating device for heating the heat shrinkable tube, a conveying device for sequentially transporting the clamping device along the hot melt adhesive ring feeding device, the solder ring feeding device, the heat shrinkable tube feeding device and the heating device, and a discharging device for unloading and removing the assembled heat shrinkable tube from the clamping device; the clamping device includes a guide member, a clamping frame, an upper mounting rod, a lower mounting rod, an upper driver and a lower driver. The guide member is arranged on the clamping frame and has a guide hole for the upper mounting rod and the lower mounting rod to pass through. The lower mounting rod sequentially has a lower guiding portion, a solder ring fixing portion, a lower hot melt adhesive ring fixing portion and a lower driving portion from top to bottom. The diameters of the lower guiding portion, the solder ring fixing portion and the lower hot melt adhesive ring fixing portion increase in sequence. The lower driving portion is driven by the lower driver and moves vertically. The upper mounting rod sequentially has an upper guiding portion, an upper hot melt adhesive ring fixing portion and an upper driving portion from bottom to top. The diameter of the upper guiding portion is smaller than that of the upper hot melt adhesive ring fixing portion. The upper driving portion is driven by the upper driver and moves vertically. The upper mounting rod and the lower mounting rod are located on the same vertical line. The heating device is a conventional setting and is not described in detail. At the same time, a hinge is arranged on the clamping device so that the heat shrinkable tube on the clamping device can rotate during heating and is heated evenly.

[0006] By adopting the above technical solution, during assembly, first, two hot melt adhesive rings are fed onto the lower mounting rod and the upper mounting rod by the hot melt adhesive ring feeding device, and then a solder ring is fed onto the lower mounting rod by the solder ring feeding device, and then a heat shrinkable tube is fed by the heat shrinkable tube feeding device. During this process, the solder ring and the heat shrinkable tube are clamped on the upper mounting rod and the lower mounting rod. Then, the upper mounting rod moves upward and the lower mounting rod moves downward, and the heat shrinkable tube moves into the gap vacated between the upper mounting rod and the lower mounting rod. Then, the upper mounting rod and the lower mounting rod move back to their original positions. During the movement, the upper mounting rod and the lower mounting rod penetrate into the heat shrinkable tube. Then, the conveying device continues to drive the clamping device to move to the heating device, and the heating device heats the heat shrinkable tube, causing the heat shrinkable tube to deform and contact the solder ring and the hot melt adhesive ring more closely. Then, the discharging device takes out the assembled heat shrink rod from the clamping device. During the clamping process, the lower mounting rod first receives a hot melt adhesive ring and clamps it to the lower hot melt adhesive fixing part, and then the lower mounting rod receives the solder ring and clamps it to the solder ring fixing part. And since the diameter of the center of the solder ring is smaller than the diameter of the hot melt adhesive ring, there will be no phenomenon that the hot melt adhesive ring is clamped at the solder ring fixing part. The upper mounting rod only needs to clamp one hot melt adhesive ring, and the positions of the hot melt adhesive ring and the solder ring in the heat shrinkable tube can be determined by the positions of the solder ring fixing part and the lower hot melt adhesive ring fixing part in the lower mounting rod. The positions of the solder ring and the hot melt adhesive ring in the heat shrinkable tube are accurately positioned, and the whole process is efficient.

[0007] The present invention is further configured as follows: the guiding member includes a rotating rod, a fixed rod, a left clamping block and a right clamping block. The left clamping block has a left fixing part, a left rotating part and a left guiding part. The right clamping block has a right fixing part, a right rotating part and a right guiding part. The left fixing part is provided with a left fixing semi-hole in a semi-circular shape, and the right fixing part is provided with a right fixing semi-hole in a semi-circular shape. The left fixing semi-hole and the right fixing semi-hole form a fixing hole adapted to the fixed rod. The left rotating part and the right rotating part are respectively provided with rotating holes rotatably engaged with the rotating rod. The left guiding part is provided with a left guiding semi-hole in a semi-circular shape, and the right guiding part is provided with a right guiding semi-hole in a semi-circular shape. The left clamping block and the right clamping block are rotatably arranged on the rotating rod. The fixed rod is provided with an inwardly recessed annular groove and the annular groove is adapted to the fixing hole. The left clamping block and the right clamping block are arranged in an alternating manner to form a fixing hole and the fixing hole is located in the annular groove. The left guiding semi-hole and the right guiding semi-hole form a guiding hole adapted to the diameter of the heat shrinkable tube. The clamping frame is provided with a protruding block. The protruding block is provided with a fixing groove along the transverse direction. The protruding block is respectively provided with fitting holes adapted to the rotating rod and the fixed rod along the longitudinal direction and the fitting holes extend into the fixing groove. The left clamping block and the right clamping block are detachably arranged in the fixing groove.

[0008] By adopting the above technical solution, when the guiding member is installed on the clamping bracket, first, parts of the left clamping block and the right clamping block are placed into the fixing groove, and then the rotating rod and the fixing rod are respectively passed through the fixing hole and the rotating hole, so that the fixing hole formed by the left clamping block and the right clamping block is located in the annular groove, thereby restricting the up-and-down movement of the left clamping block and the right clamping block, and the rotating hole is rotatably arranged on the rotating rod, which restricts the horizontal movement of the left clamping block and the right clamping block. Finally, the left clamping block and the right clamping block are detachably fixed in the fixing groove through screws, completing the installation of the guiding member. The setting of the guiding member makes the upper mounting rod or the lower mounting rod move more smoothly without jitter, and the guiding member can be detached from the clamping bracket, which is convenient for installation and replacement. Moreover, the fixing groove does not need to match the shape of the left clamping block or the right clamping block, making the production simpler.

[0009] The present invention is further configured as follows: The solder ring feeding device includes a solder ring vibrating tray, a solder ring conveying track, a transfer block, a transverse cylinder, a longitudinal cylinder and a pushing block. The solder ring conveying track includes a first longitudinal track, a transverse track and a second longitudinal track. The first longitudinal track is parallel to the second longitudinal track, the transverse track is perpendicular to the first longitudinal track and the second longitudinal track, and the first longitudinal track, the transverse track and the second longitudinal track are connected end to end in sequence. The solder ring vibrating tray transmits the solder rings to the first longitudinal track and pushes them along the first longitudinal track. The transfer block is arranged on the transverse track and is driven by the transverse cylinder to move along the transverse track. A receiving through groove for receiving the solder rings is arranged on the transfer block. The pushing block is slidably arranged on the second longitudinal track and is driven by the longitudinal cylinder. A through hole is arranged at the end of the second longitudinal track. The receiving block has a receiving position and a feeding position. The receiving position is where the receiving through groove is located at the intersection of the first longitudinal track and the transverse track, and the feeding position is where the receiving through groove is located at the intersection of the second longitudinal track and the transverse track. The second longitudinal track can be divided into two parts along the through hole. When the lower mounting rod or the upper mounting rod passes through, the second longitudinal track will separate, so that the solder ring on the through hole can be smoothly taken away. Springs can be arranged on the second longitudinal track to make the second longitudinal track reset, or a robotic arm can also be used to take away the solder rings. The structure of the hot melt adhesive ring feeding device is substantially the same as that of the solder ring feeding device, so it will not be described repeatedly.

[0010] By adopting the above technical solution, when feeding the solder rings, first, the solder ring vibrating tray pushes the solder rings along the first longitudinal track until the end of the first longitudinal track and the transverse track. At this time, the solder rings are located in the receiving through groove of the transfer block. Then, the transverse cylinder drives the transfer block to move along the transverse track to the feeding position. Then, the longitudinal cylinder drives the pushing block to push the solder rings in the receiving through groove to the end of the second longitudinal track and opposite to the through hole. When the solder rings need to be taken away, the lower mounting rod passes through the through hole, driving the solder rings above the through hole to move upward during this process and separating the second longitudinal track to take away the solder rings, completing the feeding of the solder rings.

[0011] The present invention is further configured as follows: The heat shrinkable tube feeding device includes a heat shrinkable tube vibrating tray, a transfer tube, a vertical block, a transfer cylinder, a transfer block, a horizontal block, a clamping jaw, and a pushing cylinder. A vertically arranged vertical track hole is provided on the vertical block. The heat shrinkable tube vibrating tray conveys the heat shrinkable tubes along the transfer tube to the vertical track hole. The transfer block is slidably arranged on the horizontal block. A communication port is provided on the horizontal block, and the communication port faces the clamping jaw. The pushing cylinder drives the clamping jaw to move. A transfer hole adapted to the heat shrinkable tube is provided on the transfer block. The transfer cylinder drives the transfer block to move and enables the transfer block to have a receiving position and a conveying position. The receiving position is where the transfer hole faces the vertical track hole, and the conveying position is where the transfer hole faces the communication port.

[0012] By adopting the above technical solution, when feeding the heat shrinkable tubes, first, the vibrating tray transfers the heat shrinkable tubes from the transfer tube to the vertical track hole, which is received by the transfer block. Driven by the transfer cylinder, the transfer block moves from the receiving position to the conveying position. The heat shrinkable tubes fall from the transfer hole through the communication port into the clamping jaw, and the pushing cylinder drives the clamping jaw to move to the clamping device.

[0013] The present invention is further configured as follows: The conveying device includes a frame, an indexing plate, and an indexing plate driving motor. The indexing plate driving motor is arranged on the frame and drives the indexing plate to rotate. A plurality of clamping devices are fixedly arranged circumferentially on the indexing plate and rotate synchronously with the indexing plate.

[0014] The present invention is further configured as follows: The unloading device includes a downward-sloping chute, a rotating motor, and a blanking clamping jaw. The downward-sloping chute is arranged on the frame and is located between the heating device and the hot melt adhesive ring feeding device. The rotating motor is arranged on the frame and drives the blanking clamping jaw to remove the hot melt tube in the clamping device and transfer it above the downward-sloping chute.

[0027] Such as Figures 1-10As shown in the figure, the present invention discloses an automatic assembly device for a solder ring heat shrinkable tube, which includes a clamping device 1 for assembling and clamping a solder ring and a hot melt adhesive ring on the heat shrinkable tube, a solder ring feeding device 2 for feeding and conveying the solder ring to the clamping device 1, a hot melt adhesive ring feeding device 3 for feeding and conveying the hot melt adhesive ring to the clamping device 1, a heat shrinkable tube feeding device 4 for feeding and conveying the heat shrinkable tube to the clamping device 1, a heating device 5 for heating the heat shrinkable tube, a conveying device 6 for sequentially conveying the clamping device 1 along the hot melt adhesive ring feeding device 3, the solder ring feeding device 2, the heat shrinkable tube feeding device 4 and the heating device 5, and a discharging device 7 for unloading and removing the assembled heat shrinkable tube from the clamping device 1;The clamping device 1 includes a guide member 11, a clamping frame 12, an upper mounting rod 13, a lower mounting rod 14, an upper driver 15 and a lower driver 16. The guide member 11 is disposed on the clamping frame 12 and has a guide hole 153 for the upper mounting rod 13 and the lower mounting rod 14 to pass through. The lower mounting rod 14 successively has a lower guiding portion 141, a solder ring fixing portion 142, a lower hot melt adhesive ring fixing portion 143 and a lower driving portion 144 from top to bottom. The diameters of the lower guiding portion 141, the solder ring fixing portion 142 and the lower hot melt adhesive ring fixing portion 143 increase successively. The lower driving portion 144 is driven by the lower driver 16 and moves vertically. The upper mounting rod 13 successively has an upper guiding portion 131, an upper hot melt adhesive ring fixing portion 132 and an upper driving portion 133 from bottom to top. The diameter of the upper guiding portion 131 is smaller than that of the upper hot melt adhesive ring fixing portion 132. The upper driving portion 133 is driven by the upper driver 15 and moves vertically. The upper mounting rod 13 and the lower mounting rod 14 are located on the same vertical line. The heating device 5 is a conventional setting and thus is not described in detail. At the same time, a hinge is provided on the clamping device 1 so that the heat shrinkable tube on the clamping device 1 can rotate during heating, and the heat is evenly distributed. During assembly, first, the two hot melt adhesive rings are fed onto the lower mounting rod 14 and the upper mounting rod 13 by the hot melt adhesive ring feeding device 3, then a solder ring is fed onto the lower mounting rod 14 by the solder ring feeding device 2, and then the heat shrinkable tube is fed by the heat shrinkable tube feeding device 4. During this process, the solder ring and the heat shrinkable tube are clamped on the upper mounting rod 13 and the lower mounting rod 14. Then, the upper mounting rod 13 moves upward and the lower mounting rod 14 moves downward.

Then the upper mounting rod 13 and the lower mounting rod 14 move back to their original positions. During the movement, the upper mounting rod 13 and the lower mounting rod 14 penetrate into the heat shrinkable tube. Then the conveying device 6 continues to drive the clamping device 1 to move to the heating device 5. The heating device 5 heats the heat shrinkable tube, causing the heat shrinkable tube to deform and contact the solder ring and the hot melt adhesive ring more closely. Then the completed assembled heat shrink rod is taken out of the clamping device 1 by the unloading device 7. During the clamping process, the lower mounting rod 14 first receives a hot melt adhesive ring and clamps it on the lower hot melt adhesive fixing portion. The lower mounting rod 14 then receives the solder ring and clamps it on the solder ring fixing portion 142. And since the diameter of the center of the solder ring is smaller than that of the hot melt adhesive ring, there will be no phenomenon that the hot melt adhesive ring is clamped on the solder ring fixing portion 142. The upper mounting rod 13 only needs to clamp one hot melt adhesive ring. The positions of the hot melt adhesive ring and the solder ring in the heat shrinkable tube can be determined by the positions of the solder ring fixing portion 142 and the lower hot melt adhesive ring fixing portion 143 in the lower mounting rod 14. The positions of the solder ring and the hot melt adhesive ring in the heat shrinkable tube are accurately positioned, and the whole process is efficient.;

The solder ring vibrating tray 21 transports the solder rings to the first longitudinal track 221 and pushes them along the first longitudinal track 221. The transfer block 23 is arranged on the transverse track 222 and is driven by the transverse cylinder 24 to move along the transverse track 222. A receiving through groove 231 for receiving the solder rings is arranged on the transfer block 23.

A through hole 2231 is arranged at the end of the second longitudinal track 223. The receiving block has a material receiving position and a material feeding position. The material receiving position is where the receiving through groove 231 is located at the intersection of the first longitudinal track 221 and the transverse track 222, and the material feeding position is where the receiving through groove 231 is located at the intersection of the second longitudinal track 223 and the transverse track 222. The second longitudinal track 223 can be divided into two parts along the through hole 2231. When the lower mounting rod 14 or the upper mounting rod 13 passes through, the second longitudinal track 223 will separate, so that the solder rings on the through hole 2231 can be smoothly taken away. Springs can be arranged on the second longitudinal track 223 to reset the second longitudinal track 223. Alternatively, a robotic arm can be used to take away the solder rings. The structure of the hot melt adhesive ring feeding device 3 is substantially the same as that of the solder ring feeding device 2, so it will not be described repeatedly. When feeding the solder rings, first, the solder ring vibrating tray 21 pushes the solder rings along the first longitudinal track 221 until the end of the first longitudinal track 221 and the transverse track 222. At this time, the solder rings are located in the receiving through groove 231 of the transfer block 23. Then, the transverse cylinder 24 pushes the transfer block 23 to move along the transverse track 222 to the material feeding position. Then, the longitudinal cylinder 25 drives the pushing block 26 to push the solder rings in the receiving through groove 231 to the end of the second longitudinal track 223 and make them opposite to the through hole 2231. When the solder rings need to be taken away, the lower mounting rod 14 passes through the through hole 2231.

A vertically arranged vertical track hole 431 is provided on the vertical block 43. The heat shrinkable tube vibrating disk 41 conveys the heat shrinkable tubes along the transmission tube 42 to the vertical track hole 431. The material shifting block 45 is slidably arranged on the horizontal block 48. A communication port 481 is provided on the horizontal block 48, and the communication port 481 faces the clamping jaw 46. The pushing cylinder 47 pushes the clamping jaw 46 to move. A material shifting hole 451 adapted to the heat shrinkable tube is provided on the material shifting block 45. The material shifting cylinder 44 drives the material shifting block 45 to move and enables the material shifting block 45 to have a receiving position and a conveying position. The receiving position is when the material shifting hole 451 faces the vertical track hole 431, and the conveying position is when the material shifting hole 451 faces the communication port 481. When feeding the heat shrinkable tubes, first, the vibrating disk conveys the heat shrinkable tubes from the transmission tube 42 into the vertical track hole 431, which is received by the material shifting block 45. Driven by the material shifting cylinder 44, the material shifting block 45 moves from the receiving position to the conveying position.

[0031] The conveying device 6 includes a frame 61, an indexing plate 62 and an indexing plate driving motor 63. The indexing plate driving motor 63 is arranged on the frame 61 and drives the indexing plate 62 to rotate.

[0032] The discharging device 7 includes a downward-sloping chute 71, a rotating motor 72 and a discharging clamping jaw 73. The downward-sloping chute 71 is arranged on the frame 61 and is located between the heating device 5 and the hot melt adhesive ring feeding device 3. The rotating motor 72 is arranged on the frame 61 and drives the discharging clamping jaw 73 to remove the heat shrinkable tube in the clamping device 1 and transfer it above the downward-sloping chute 71. During the discharging process, the discharging clamping jaw 73 clamps the heat shrinkable tube, and then the upper mounting rod 13 and the lower mounting rod 14 move away from each other. Since the contact force between the heat shrinkable tube and the hot melt adhesive ring and the solder ring is greater than the clamping force, the heat shrinkable tube with the hot melt adhesive ring and the solder ring can be directly taken out.

[0033] Specific Embodiment: During assembly, first, the hot melt adhesive ring feeding device 3 feeds two hot melt adhesive rings onto the lower mounting rod 14 and the upper mounting rod 13. Then, the solder ring vibrating disk 21 pushes the solder ring along the first longitudinal track 221 until it reaches the end of the first longitudinal track 221 and the transverse track 222. At this time, the solder ring is located in the receiving through groove 231 of the transfer block 23. Then, the transverse cylinder 24 drives the transfer block 23 to move along the transverse track 222 to the feeding position. Then, the longitudinal cylinder 25 drives the pushing block 26 to push the solder ring in the receiving through groove 231 to the end of the second longitudinal track 223 and align it with the through hole 2231. The lower mounting rod 14 moves upward to feed a solder ring onto the lower mounting rod 14. Then, the heat shrinkable tube vibrating disk 41 transfers the heat shrinkable tube from the transmission tube 42 to the vertical track hole 431, which is received by the transfer block 45. Driven by the transfer cylinder 44, the transfer block 45 moves from the receiving position to the conveying position. The heat shrinkable tube falls from the transfer hole 451 through the communication port 481 into the gripper 46, and the pushing cylinder 47 drives the gripper 46 to move to the clamping device 1. Then, the conveying device 6 continues to drive the clamping device 1 to move to the heating device 5. The heating device 5 heats the heat shrinkable tube, causing the heat shrinkable tube to deform and contact the solder ring and the hot melt adhesive ring more closely. Then, the unloading device 7 takes out the assembled heat shrink rod from the clamping device 1.
