DETAILED DESCRIPTION

[0023] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0024] like Figures 1 to 5 As shown, the present invention provides a tape wrapping machine, which includes a machine platform 1, a turntable 2 rotatably arranged on the machine platform 1, two jig supports 4 movably connected to the turntable 2, two jigs 5 rotatably connected to the two jig supports 4, a jig driving device 6 for drivingly connecting to one of the jigs 5, and a tape supply device 7, a shearing device 8 and an adjusting device 3 respectively arranged on the machine platform 1, wherein the jig 5 is used to clamp electronic components, the tape supply device 7 is used to convey the tape to the electronic components clamped by the jig 5; the shearing device 8 is used to cut the tape supplied by the tape supply device 7 The adhesive tape should be wrapped around the electronic components clamped by the jig 5; the adjusting device 3 includes a shifting mechanism 32 driven and connected to the jig driving device 6, an adjusting mechanism 31 for driving the two jig supports 4 to move closer to or away from each other, and a linkage mechanism 33 driven and connected to the adjusting mechanism 31 and the shifting mechanism 32 respectively; specifically, the turntable 2 has a glue coating station and a loading and unloading station, the glue coating station is arranged close to the tape supply device 7, and the loading and unloading station is arranged away from the tape supply device 7, and the jig driving device 6 is used to be driven and connected to the jig 5 at the glue coating station.

[0025] Specifically, the linkage mechanism 33 is used to drive the shifting mechanism 32 and the adjusting mechanism 31 to move synchronously, so that the shifting mechanism 32 drives the jig support 4 to move and the adjusting mechanism 31 drives the jig drive device 6 to move, and at this time the jig support 4 and the jig drive device 6 move synchronously; the two jig supports 4 are symmetrically arranged along the central axis of the turntable 2, and the tape wrapping machine also includes a turntable drive device 21 connected to the turntable 2, and the output end of the turntable drive device 21 drives the turntable 2 to rotate on the machine 1 along the central axis of the turntable 2, and the rotating turntable 2 drives the two jigs 5 to rotate synchronously, so that the two jigs 5 switch between the rubber wrapping station and the loading and unloading stations. This rubber wrapping machine can be widely used in the rubber wrapping of electronic components. This embodiment is explained by taking the rubber wrapping of transformers as an example. In actual use, at the beginning, the two jigs 5 are respectively located at the glue coating station and the loading and unloading station, the jig driving device 6 is connected to the jig 5 at the glue coating station, and the external material moving device can load and unload the jig 5 at the loading and unloading station; first, the free end of the tape delivered by the tape supply device 7 is pasted on one side of the transformer clamped by the jig 5 at the glue coating station, and then the jig driving device 6 drives the jig 5 and the transformer clamped by the jig 5 to move relatively along the central axis of the jig 5. The corresponding jig support 4 rotates (such as: rotating 360° or 720°, etc.). During this process, the tape is wound on the transformer, so that all sides of the transformer clamped by the jig 5 are wound with tape, and the transformer clamped by the jig 5 is wrapped with tape. Then, the turntable 2 is driven by the turntable driving device 21 to rotate the two jig supports 4 180° along the central axis of the turntable 2, so that the two jigs 5 exchange positions, that is, the jig 5 originally located at the rubber coating station is rotated to the loading and unloading station, and the jig 5 originally located at the loading and unloading station is rotated to the loading and unloading station. The jig 5 rotates to the rubber coating station. During this process, the jig driving device 6 is not connected to the jig 5 that has completed the rubber coating, but is connected to the jig 5 that has just rotated to the rubber coating station. The tape will be attached to one side of the transformer clamped by the jig 5 at the rubber coating station, and then the tape wrapped between the two transformers will be cut by the shearing device 8. The external material moving device will remove the completed rubber coated transformer clamped by the jig 5 at the loading and unloading station, and move the transformer to be rubber coated to the unloaded jig. 5; since the turntable 2 drives the two jig supports 4 and the two jigs 5 to rotate 180° respectively, the positions of the two jig supports 4 and the two jigs 5 can be swapped, so that the jig drive device 6 is always connected to the jig 5 located at the rubber coating station, and the jig drive device 6 can drive the two jigs 5 to rotate in turn to complete the rubber tape coating, so that all sides of the transformer clamped by the jig 5 are wrapped with tape, and the above actions are repeated to continuously realize the rubber tape coating of the transformer and the loading and unloading of the transformer.

[0026] When installing the tape wrapping machine, first install the two jigs 5 on the two jig supports 4 respectively, then symmetrically arrange the two jig supports 4 on the turntable 2 and connect them to the adjustment mechanism 31 respectively, and then connect the jig drive device 6 to the shift mechanism 32, adjust the position of the jig drive device 6 connected to the shift mechanism 32, so that the jig drive device 6 is driven and connected to one of the jigs 5, and then drive and connect the linkage mechanism 33 to the adjustment mechanism 31 and the shift mechanism 32 respectively. When the tape wrapping machine wraps transformers of different sizes, the linkage mechanism 33 drives the adjustment mechanism 31 and the shifting mechanism 32 to move synchronously. The adjustment mechanism 31 drives the two jig supports 4 to move away from or close to each other during movement. The shifting mechanism 32 drives the jig driving device 6 and one of the jigs 5 to move the same distance in the same direction during movement. The jig support 4 drives the jig 5 to move synchronously so that the distance between the two jigs 5 increases or decreases. After the two jigs 5 are adjusted to a suitable distance, the linkage mechanism 33 controls the adjustment mechanism 31 and the shifting mechanism 32 to stop moving, and the adjustment of the tape wrapping machine is completed to meet the requirements of the tape wrapping of transformers of different sizes. In the process of adjusting the spacing between the jig supports 4, the two jig supports 4 always move in opposite directions by the same distance, that is, the distances that the two jig supports 4 move toward or away from each other are the same, the two jig supports 4 and the two jigs 5 are always symmetrically arranged along the central axis of the turntable 2, the jig drive device 6 moves synchronously with one of the jig supports 4 and one of the jigs 5, that is, the relative positions of the jig drive device 6 and one of the jig supports 4 and the jig 5 will not change, and the turntable drive device 21 drives the turntable 2 to drive the two jig supports 4 and the two jigs 5 to rotate 180° along the central axis of the turntable 2, so that the two jigs 5 can be alternately driven and connected to the jig drive device 6. The adhesive tape machine only needs to adjust the position between the jig drive device 6 and the two jigs 5 when assembling the adhesive tape machine. When the adhesive tape machine is used for rubberizing transformers of different sizes, there is no need to adjust the relative position between the jig drive device 6 and the jig support 4 and the jig 5, thereby improving the matching accuracy between the jig drive device 6 and the two jigs 5. The jig drive device 6 has strong stability when driving the jig 5 to rotate. The adhesive tape machine has a simple structure, a high degree of automation, and a high adjustment efficiency, which saves workers time in adjusting the adhesive tape machine. The adhesive tape machine can rubberize electronic components of different sizes, and has strong practicality and high utilization rate.

[0027] Furthermore, the tape wrapping machine also includes a base plate 11 arranged under the machine table 1, the jig driving device 6 includes a sliding seat 61 slidably connected to the base plate 11 and a jig driver 62 installed on the sliding seat 61, the output end of the jig driver 62 can be alternately driven and connected to two jigs 5, and the shifting mechanism 32 is driven and connected to the sliding seat 61.

[0028] Specifically, the jig driver 62 can be a motor. In actual use, the linkage mechanism 33 drives the adjustment mechanism 31 and the shift mechanism 32 to move synchronously, and the shift mechanism 32 drives the sliding seat 1 61 and the jig driver 62 to slide back and forth along the substrate 11, so that the sliding seat 1 61 and the jig driver 62 move synchronously with one of the jig supports 4; this structural design improves the stability of the adjustment jig driver 62.

[0029] Furthermore, the shift mechanism 32 includes a screw rod 34 that penetrates the sliding seat 61 and is threadedly connected to the sliding seat 61. The screw rod 34 is rotatably disposed on the base plate 11, and the output end of the linkage mechanism 33 is drivingly connected to one end of the screw rod 34.

[0030] Specifically, the substrate 11 includes a substrate body, a slide rail 12 arranged at the bottom end of the substrate body, a sliding cavity 13 arranged on the substrate body and two mounting seats 14 arranged on both sides of the sliding cavity 13, the sliding seat 61 is provided with an adjusting block 63 slidably connected to the slide rail 12, and the adjusting block 63 protrudes into the sliding cavity 13; the adjusting block 63 is threadedly connected with a locking member, and the locking member can be a bolt, the locking member is threadedly connected to the adjusting block 63, and the end of the locking member is used to abut against the side wall of the screw rod 34, the adjusting block 63 is located between the two mounting seats 14, one end of the screw rod 34 is rotatably connected to a mounting seat 14, the other end of the screw rod 34 sequentially penetrates the adjusting block 63 and the other mounting seat 14 and is connected to the linkage mechanism 33, the screw rod 34 is threaded or slidably connected to the adjusting block 63, and the screw rod 34 is rotatably connected to the other mounting seat 14. When the position of the sliding seat 61 needs to be adjusted, the locking piece is loosened so that the adjusting block 63 can move relative to the screw rod 34, and the linkage mechanism 33 drives the screw rod 34 to rotate. Since the sliding seat 61 is threadedly connected to the screw rod 34, the rotation of the screw rod 34 will drive the sliding seat 61, the adjusting block 63 and the fixture driver 62 to move back and forth along the length direction of the screw rod 34, and the adjusting block 63 slides back and forth in the sliding cavity 13. When the position of the sliding seat 61 is adjusted, the locking piece is tightened so that the end of the locking piece contacts the side wall of the screw rod 34, thereby locking the adjusting block 63 on the screw rod 34, so that the adjusting block 63 and the screw rod 34 cannot move or rotate relative to each other, thereby ensuring the position accuracy and stability of the sliding seat 61. The sliding cavity 13 provides a space for the adjustment block 63 to move. The inner wall of the sliding cavity 13 can contact the adjustment block 63 to limit the adjustment block 63 and ensure that the adjustment block 63 can only move in the sliding cavity 13 to limit the moving stroke of the sliding seat 61, thereby improving the stability of the movement of the sliding seat 61. The adjustment block 63 is located in the sliding cavity 13, so that the structure of the sliding seat 61 and the base plate 11 is compact, the volume of the machine is reduced, and the sliding stroke of the sliding seat 61 is increased; the structure of the shifting mechanism 32 is simple, the position adjustment of the fixture driver 62 is convenient, the error when the sliding seat 61 and the fixture driver 62 move along the screw rod 34 is small, and the additional slide rail 12 realizes the directional movement of the fixture driver 62, thereby improving the stability of the fixture drive device 6 during the adjustment process and improving the tape quality of the tape wrapping machine.

[0031] Furthermore, the adjustment mechanism 31 includes a screw rod 35 that passes through two jig supports 4 in sequence, and the screw rod 35 is rotatably set on the machine table 1 or the base plate 11, and the linkage mechanism 33 is drivingly connected to the screw rod 1 34 and the screw rod 2 35 respectively; the screw rod 2 35 is provided with a positive thread segment and a negative thread segment, the positive thread segment is threadedly connected to one jig support 4, and the negative thread segment is threadedly connected to the other jig support 4; preferably, the thread on the screw rod 1 34 is a positive thread.

[0032] Specifically, the screw rod 1 34 is arranged in parallel with the screw rod 2 35; the pitch of the screw rod 1 34, the pitch of the orthodontic thread segment and the pitch of the anti-thread segment are all equal; in actual use, the linkage mechanism 33 simultaneously drives the screw rod 1 34 and the screw rod 2 35 to rotate in the same direction, so that the jig driver 62 moves along the screw rod 1 34, and the two jig supports 4 move closer to or away from each other along the screw rod 2 35. Since the screw rod 1 34, the pitch of the orthodontic thread segment and the pitch of the anti-thread segment are all equal, the jig driver 62 and the jig support 4 installed on the orthodontic thread segment always move the same distance in the same direction, thereby realizing that the jig driver 62 always moves synchronously with the jig support 4, the movement and coordination of the jig driver 62 and the jig 5 are more precise, the service life of the jig drive device 6 is improved, and the rubber wrapping efficiency of the rubber wrapping tape machine is improved.

[0033] Furthermore, a second slide rail 22 and a second slide cavity are provided on the turntable 2 , and the two fixture supports 4 are both located in the second slide cavity and are slidably connected to the second slide rail 22 .

[0034] Specifically, the bottom end of the jig 5 protrudes out of the bottom end of the jig support 4 and is connected to the jig driver 62, and the electronic component is clamped in the top end of the jig 5; the screw rod 2 35 and the screw rod 1 34 are both located between the substrate 11 and the machine 1. In actual use, the screw rod 2 35 drives the jig support 4 to slide back and forth along the slide rail 2 22, and the jig support 4 is limited and guided by the slide rail 2 22, further improving the accuracy of the jig support 4 during movement. The screw rod 1 34 and the screw rod 2 35 are arranged in the empty space between the substrate 11 and the machine 1, so that the structure of the tape wrapping machine is more compact; the two jig supports 4 move closer to or away from each other in the sliding cavity 2.

[0035] Furthermore, the linkage mechanism 33 includes a fixed plate 15 arranged on the machine 1, a driven wheel 36 rotatably arranged on the fixed plate 15 and connected to the screw rod 1 34, a driving wheel 37 rotatably arranged on the fixed plate 15 and connected to the screw rod 2 35, a transmission belt 38 connected to the driven wheel 36 and the driving wheel 37, and a handle 39 drivingly connected to one end of the driving wheel 37 or the screw rod 2 35.

[0036] In actual use, the handle 39 can be connected to the drive motor, and the driving wheel 37 can be driven to rotate manually or by the drive motor. The driving wheel 37 drives the driven wheel 36 to rotate in the same direction through the transmission belt 38, so that the screw rod 1 34 and the screw rod 2 35 rotate synchronously, so that the spacing adjustment between the two fixture supports 4 is synchronized with the position adjustment between the fixture support 4 and the fixture driver 62. The adjustment device 3 has a simple structure, simple production, high adjustment accuracy, good transmission synchronization, and a high degree of fit between the adjusted fixture driver 62 and the fixture support 4, which improves the service life of the fixture driver 62 and the fixture support 4. The driving wheel 37 and the driven wheel 36 are arranged on the fixed plate 15, which improves the stability of the linkage mechanism 33 during use.

[0037] Specifically, the jig drive device 6 also includes an axial hole provided on the output shaft of the jig driver 62, an induction coil 64 sleeved on the output end of the jig driver 62, an inductor provided on the sliding seat 61 and electrically connected to the induction coil 64, and a mounting hole provided on the induction coil 64 and interconnected with the axial hole, and a locking piece passes through the mounting hole and the axial hole in sequence to fix the induction coil 64 on the output shaft of the jig driver 62. When the output shaft of the jig driver 62 rotates, the connection between the induction coil 64 and the jig drive device 6 is more stable and not easy to slip or deviate. In actual use, the induction coil 64 rotates synchronously with the output end of the jig driver 62. When the inductor senses that the induction coil 64 rotates one circle (about 360°), the jig driver 62 is controlled to stop moving through the control center, and the induction coil 64 is provided on the jig driver 62, which can be used to accurately sense the rotation angle of the output end of the jig driver 62, thereby improving the accuracy of the transformer tape wrapping and avoiding tape waste. When the sliding seat 61 slides, the sensor moves synchronously with the sliding seat 61. There is no need to adjust the relative position of the sensor and the sliding seat 61. It is only necessary to adjust the position of the sensor and the induction coil 64 during installation, which further simplifies the adjustment steps of the tape wrapping machine and improves the adjustment efficiency.

[0038] Furthermore, the tape wrapping machine also includes a pressing device 9, which includes a lifting drive mechanism 91 arranged on the machine platform 1, a lifting frame 92 driven and connected to the output end of the lifting drive mechanism 91, a rotating driver 93 arranged on the lifting frame 92, a connecting frame 94 driven and connected to the output end of the rotating driver 93, and a resistance member 95 rotatably arranged on the connecting frame 94, and the resistance member 95 is used to press the electronic components clamped by the fixture 5.

[0039] Specifically, the rotary drive 93 can adopt a motor, and the number of the resistance members 95 is two, and the two resistance members 95 are respectively located directly above the two jigs 5. In actual use, after the external material moving device transfers the transformer to the jig 5, the lifting drive mechanism 91 drives the lifting frame 92, the connecting frame 94 and the resistance member 95 to move in the direction close to the jig 5 until the resistance member 95 is pressed against the transformer clamped by the jig 5, and then the jig driver 62 drives a jig 5 and the transformer clamped on this jig 5 to rotate synchronously, and the transformer drives the resistance member 95 to rotate relative to the connecting frame 94 until the sides of the transformer are all wrapped with tape. When wrapping the tape, the resistance member 95 always presses the transformer, which improves the stability of the transformer when wrapping the tape, thereby improving the quality of the transformer wrapping the tape; then the turntable drive device 21 drives the two jig supports 4 to rotate along the central axis of the turntable 2, and the rotation The driver 93 drives the connecting frame 94 and the resistance member 95 to rotate synchronously along the central axis of the turntable 2 until another jig 5 is driven and connected to the jig driver 62. During this process, the resistance member 95 always presses the transformer, thereby improving the stability of the transformer when wrapped with adhesive tape; the adhesive tape wrapped between the two transformers is cut off by the shearing device 8, and then the lifting drive mechanism 91 drives the resistance member 95 to move away from the jig 5, so that the resistance member 95 releases the resistance and limit to the transformer, and the external material moving device removes the transformer that has been wrapped on the jig 5. At the same time, the external material moving device moves the transformer to be wrapped with adhesive tape to this jig 5, and the tape wrapping machine repeats the above action to wrap the next transformer, thereby realizing automatic tape wrapping of the transformer.

[0040] When the turntable drive device 21 and the rotary driver 93 respectively drive the jig support 4 and the connecting frame 94 to rotate synchronously, the rotation angles of the connecting frame 94 and the turntable 2 may be asynchronous or the relative positions of the two may be offset. Since the resistance member 95 is pressed against the transformer, the resistance member 95 can be driven by the transformer to rotate relative to the connecting frame 94 to eliminate the position deviation between the resistance member 95 and the transformer when the connecting frame 94 and the turntable 2 are asynchronous, so as to avoid the connecting frame 94 driving the resistance member 95 to pull or push the transformer, causing the transformer to move relative to the jig 5, causing damage or offset of the transformer, and affecting the accuracy of the transformer when the tape is wrapped.

[0041] Furthermore, the connecting frame 94 includes a fixing block 96 rotatably connected to the abutment member 95 and a connecting plate 97 detachably connected to the fixing block 96 , and the connecting plate 97 is drivingly connected to the rotary driver 93 .

[0042] Specifically, there are two fixed blocks 96, and a plurality of connection holes 1 are provided on the fixed block 96. Two connection holes 2 are symmetrically provided on the connection plate 97. The locking pieces are sequentially inserted into the connection holes 2 and the connection holes 1 at the corresponding positions so that the fixed block 96 is firmly connected to the connection plate 97. By selecting different connection holes 1 to connect with the connection holes 2, the position of the fixed block 96 installed on the connection plate 97 can be adjusted to adjust the distance between the two abutting members 95 respectively installed on the two fixed blocks 96, so that the distance between the two abutting members 95 is equal to the distance between the two jigs 5, thereby improving the practicability of the tape wrapping machine.

[0043] Furthermore, a slide rail three 16 is also provided on the machine 1, and the shearing device 8 includes a shearing driver 81, a cutting knife assembly and a sliding block 82 slidably connected to the slide rail three 16, the shearing driver 81 is driven and connected to the sliding block 82 through a crank arm, and the cutting knife assembly is installed on the sliding block 82; preferably, the shearing driver 81 is a linear driving module, and the shearing driver 81 is installed on the machine 1.

[0044] During actual use, the shearing driver 81 drives the sliding block 82 and the cutter assembly through the crank arm to move along the slide rail 3 16 toward the direction close to the jig 5 until the tape wrapped around the two transformers is located within the shearing end of the cutter assembly. The cutter assembly cuts the tape wrapped around the two transformers, thereby improving the degree of automation of the tape wrapping machine.

[0045] Furthermore, the cutter assembly includes a knife holder 83 arranged on the sliding block 82, a blade (not shown in the figure) installed on the knife holder 83, a fixed guide column 86 arranged through the knife holder 83, two guide rods 84 respectively inserted into the two ends of the fixed guide column 86, and two springs 85 respectively connected to the two guide rods 84, and the front end of the blade protrudes from the front end of the spring 85.

[0046] In actual use, the two jigs 5 are symmetrically arranged on both sides of the blade holder 83. When the shearing driver 81 drives the sliding block 82 to slide on the slide rail 3 16 toward the jig 5, the blade first cuts the tape to form a separate tape segment. After the blade cuts the tape, the shearing driver 81 continues to drive the sliding block 82 to move forward on the slide rail 3 16 toward the jig 5, so that the two springs 85 respectively contact the transformers clamped by the two jigs 5. Under the elastic force of the two springs 85, the two springs 85 press and fit the free ends of the tape and the free ends of the tape segments to the two transformers. When the tape wrapping machine is used to wrap transformers of different sizes, the depth of the guide rod 84 inserted into the fixed guide column 86 can be adjusted to reduce or increase the spacing between the two spring pieces 85, so that the distance between the two spring pieces 85 corresponds to the distance between the two jigs 5, which makes it easier for the free ends of the cut tape and the tape segment to fit the transformers clamped by the two jigs 5, thereby improving the degree of automation of the tape wrapping machine.

[0047] All technical features in this embodiment can be freely combined according to actual needs.

[0048] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention may also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
