Description

Technical Field

[0001] The present invention relates to the technical field of diode taping production, and particularly relates to a diode taping unwinding device. Background Art

[0002] In the TMTT process of diode products, if there are errors in the printed patterns, models, cycle codes, etc., the taped materials need to be unwound into individual pieces and then reworked by electroplating to remove the characters.

[0003] In the existing process of unwinding diodes, when using an unwinding device, after the red and white tapes on the diode tape are removed, the diodes fall freely under the action of gravity into the collection box for collection. However, the lowest position of the arc-shaped structure on the unwinding device that removes the diodes from the red and white tapes is relatively high, resulting in the situation that the diodes after unwinding start to fall freely from a relatively high height. This situation will generate a large impact on the diodes that have already fallen into the collection box. Therefore, it is not conducive to the unwinding operation of diode taping. Summary of the Invention

[0009] The unwinding mechanism includes two parallel and symmetrically arranged unwinding wheels one and two symmetrically arranged unwinding wheels two. The two unwinding wheels two are in a V shape, and the side with a larger distance formed by the two unwinding wheels two is the side close to the arc-shaped structure and serves as the unwinding outlet side;

[0010] Both of the two unwinding wheels one are located between the two unwinding wheels two and are rotationally connected to the frame through a drive shaft two. Each unwinding wheel two is rotationally connected to the frame through a drive mechanism and rotates synchronously with the unwinding wheel one;

[0011] When the unwinding wheel two rotates synchronously with the unwinding wheel one, the unwinding wheel two rotates obliquely relative to the unwinding wheel one and the inclination angle remains unchanged during the rotation;

[0012] The arc-shaped structure includes two arc-shaped plates corresponding to the tape-detaching wheels one by one, which are used for limiting the diodes during tape detachment. The two arc-shaped plates are fixed by a connecting rod and detachably connected to the frame. On one side of each arc-shaped plate close to the first tape-detaching wheel is an arc-shaped end, which forms an arc-shaped gap with the first tape-detaching wheel, and the lowest end of the arc-shaped end of the arc-shaped plate is lower than the lowest end of the first tape-detaching wheel;

[0013] A positioning groove one is formed between every two adjacent teeth on each first tape-detaching wheel, and a positioning groove two corresponding to the positioning groove one is formed between every two adjacent teeth on each second tape-detaching wheel.

[0014] Furthermore, a limiting post is detachably installed between the two first tape-detaching wheels, and the limiting post is fixed to the two first tape-detaching wheels through limiting structures two provided on both sides;

[0015] The limiting post passes through the corresponding sleeve hole on the second tape-detaching wheel and does not contact the sleeve hole.

[0016] Furthermore, a plurality of limiting posts are provided, and the plurality of limiting posts are arranged equidistantly along the circumference of the first tape-detaching wheel;

[0017] During the rotation of the first tape-detaching wheel and the gradual approach of each limiting post to the arc-shaped structure, each limiting post gradually contracts towards the corresponding sleeve hole and never disengages from the second tape-detaching wheel.

[0018] Furthermore, a cylindrical gear two is fixedly sleeved on the second driving shaft, a first driving shaft is rotatably connected to the frame, a cylindrical gear one is fixedly sleeved on the first driving shaft, the diameter of the cylindrical gear one is smaller than the diameter of the cylindrical gear two, the cylindrical gear one and the cylindrical gear two are meshed, and the first driving shaft is driven by a driving motor.

[0019] Furthermore, the frame is placed on the base and fixed to the base through a connecting block, and a cavity for placing a material collection box is formed between the frame and the ground through the base.

[0020] Furthermore, a guiding mechanism is installed at one end of the connecting block away from the frame, a first limiting roller and a second limiting roller are installed on the guiding mechanism, the second limiting roller is located directly above the first limiting roller, and a positioning gap is formed between the second limiting roller and the first limiting roller, which is used for limiting during the traction of the diode tape;

[0021] The first limiting roller is rotatably connected to the guiding mechanism through a first rotating rod, and the second limiting roller is rotatably connected to the guiding mechanism through a second rotating rod.

[0022] Furthermore, two symmetrically arranged lifting blocks are installed on the frame, and each lifting block is in an L shape and corresponds to the second tape-detaching wheel one by one;

[0023] When the tape is removed, the red tape and the white tape on the diode tape move along the surfaces of the corresponding lifting blocks respectively;

[0024] The sliding surfaces for the red tape and the white tape on each of the lifting blocks are at the same height as the highest point of the first tape removal wheel.

[0025] (III) Advantageous effects

[0026] The present invention provides a diode tape removal device. Compared with the prior art, it has the following advantageous effects:

[0027] By setting an arc structure, when setting the arc plate, the lowest end of the arc end of the arc plate is lower than the lowest end of the first tape removal wheel. When controlling the removal of the diodes on the diode tape, the diodes disassembled from the diode tape slide along the arc end and fall into the material collection box for collection, reducing the height of the diodes starting to free fall, thereby reducing the impact force on the diodes that have already fallen into the collection box, preventing the problem of diode damage, and improving the tape removal effect.

[0039] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0040] The embodiment of the present application provides a diode tape unwinding device, which solves the problem that the diode starts to free fall from a relatively high height after unwinding, and improves the unwinding effect.

[0041] To better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the accompanying drawings of the specification and specific implementation manners.

[0042] As Figures 1 - 8 shown, a diode tape unwinding device includes a frame 2 and a tape unwinding mechanism 5 and an arc structure installed inside the frame 2;

[0043] The tape unwinding mechanism 5 includes two parallel and symmetrically arranged first tape unwinding wheels 51 and two symmetrically arranged second tape unwinding wheels 52. The two second tape unwinding wheels 52 are in a V shape. The side with a larger distance formed by the two second tape unwinding wheels 52 is the side close to the arc structure and serves as the tape unwinding outlet side;

[0044] Both of the two first tape unwinding wheels 51 are located between the two second tape unwinding wheels 52 and are rotatably connected to the frame 2 through a second drive shaft 22. Each second tape unwinding wheel 52 is rotatably connected to the frame 2 through a driving mechanism 53 and rotates synchronously with the first tape unwinding wheel 51;

[0045] When the second tape removing wheel 52 rotates synchronously with the first tape removing wheel 51, the second tape removing wheel 52 rotates obliquely relative to the first tape removing wheel 51, and the inclination angle remains unchanged during the rotation process;

[0046] The arc-shaped structure includes two arc-shaped plates 6 corresponding to the first tape removing wheel 51 one by one, which are used for limiting the diode 7 during tape removal. The two arc-shaped plates 6 are fixed by a connecting rod 61 and are detachably connected to the frame 2. The side of each arc-shaped plate 6 close to the first tape removing wheel 51 is an arc-shaped end, and an arc-shaped gap 62 is formed between the arc-shaped plate 6 and the first tape removing wheel 51. Moreover, the lowest end of the arc-shaped end of the arc-shaped plate 6 is lower than the lowest end of the first tape removing wheel 51;

[0047] A first positioning groove 511 is formed between every two adjacent teeth on each first tape removing wheel 51, and a second positioning groove 521 corresponding to the first positioning groove 511 one by one is formed between every two adjacent teeth on each second tape removing wheel 52.

[0048] By setting the arc-shaped structure in the form of a combination of two arc-shaped plates 6, the arc-shaped gap 62 formed between the two arc-shaped plates 6 and the first tape removing wheel 51 is used to limit the diode 7 on the diode tape during tape removal, so as to facilitate the smooth progress of tape removal;

[0049] When setting the arc-shaped plate 6, the lowest end of the arc-shaped end of the arc-shaped plate 6 is lower than the lowest end of the first tape removing wheel 51. When controlling the removal of the diode 7 on the diode tape, the diode 7 disassembled from the diode tape slides along the arc-shaped end and drops into the material collecting box for collection, reducing the height of the free fall of the diode 7, thereby reducing the impact force on the diode 7 that has already fallen into the collection box and preventing the problem of damage to the diode 7;

[0050] Moreover, when setting the arc-shaped structure, two arc-shaped plates 6 are set, and the distance formed between the two arc-shaped plates 6 is used to limit the thicker middle part of the diode 7. The thicker middle part of the diode 7 slides along the gap, while realizing the sliding limit of the diode 7, effectively reducing the contact between the thicker middle part of the diode 7 and the arc-shaped structure, and further protecting the diode 7 after disassembly.

[0051] Specifically, when setting the driving mechanism 53, an electromagnetic bearing can be set in the driving mechanism 53, and both the driving mechanism 53 and the electromagnetic bearing are sleeved on the second driving shaft 22. The corresponding second tape removing wheel 52 is driven to rotate synchronously with the first tape removing wheel 51 by driving the electromagnetic bearing;

[0052] Moreover, the electromagnetic bearing in the driving mechanism 53 is obliquely arranged relative to the second driving shaft 22 used by the first tape removing wheel 51, so as to control the second tape removing wheel 52 to be obliquely arranged relative to the first tape removing wheel 51, and the inclination angle remains unchanged during the rotation of the first tape removing wheel 51 and the second tape removing wheel 52;

[0053] Among them, the driving mechanism 53 is fixedly connected to the frame 2, and controls the electromagnetic bearing to drive the corresponding second tape removing wheel 52 to rotate synchronously with the second driving shaft 22. During rotation, the electromagnetic bearing is suspended and does not contact the second driving shaft 22.

[0054] Specifically, a sleeve is welded between the two first tape removing wheels 51, and the sleeve is sleeved on the driving shaft 22. Moreover, the two first tape removing wheels 51 sleeved on the second driving shaft are both fixedly connected to the second driving shaft 22 through a first limiting structure 222, thereby facilitating the fixed installation of the first tape removing wheel 51.

[0055] A limiting column 531 is detachably installed between the two first tape removing wheels 51. The limiting column 531 is fixed to the two first tape removing wheels 51 through second limiting structures 532 respectively arranged on both sides.

[0056] The limiting column 531 passes through the corresponding sleeve hole 522 on the second tape removing wheel 52 and does not contact the sleeve hole 522.

[0057] By arranging the limiting column 531, the two first tape removing wheels 51 are further fixed by using the limiting column 531 and the second limiting structure 532, strengthening the stability of the two first tape removing wheels 51 during rotation. Furthermore, it can effectively reduce the deviation of the two first tape removing wheels 51 after long-term rotation, preventing the problem of inconvenient tape removal caused by the diode 7 not being accurately located in the corresponding first positioning groove 511 and the corresponding second positioning groove 521.

[0058] Meanwhile, the limiting column 531 passes through the sleeve hole 522 on the second tape removing wheel 52 and does not contact the inside of the sleeve hole 522. Therefore, once the limiting column 531 contacts the sleeve hole 522 to generate noise, it indicates that the second tape removing wheel 52 has deviated to a certain extent and needs to be repaired. The limiting column 531 plays a warning role in whether the first tape removing wheel 51 and the second tape removing wheel 52 deviate, and can timely detect the problem of deviation of the second tape removing wheel 52.

[0059] It should be noted that the first limiting structure 222 and the second limiting structure 532 are both composed of a sleeve and a positioning pin respectively. The positioning pin is used to fix the sleeve, thereby realizing the limiting operation.

[0060] A plurality of limiting columns 531 are provided, and the plurality of limiting columns 531 are arranged at equal intervals along the circumference of the first tape removing wheel 51.

[0061] During the rotation of the first tape removing wheel 51 and the gradual approach of each limiting column 531 to the arc-shaped structure, each limiting column 531 gradually contracts towards the corresponding sleeve hole 522 and never detaches from the second tape removing wheel 52.

[0062] By setting a plurality of limit posts 531, while improving the stability of the first tape removing wheel 51 and being able to give an early warning of whether the first tape removing wheel 51 and the second tape removing wheel are offset, after the first tape removing wheel 51 and the second tape removing wheel 52 are overhauled and reinstalled, by observing whether the limit posts 531 are completely separated from the tape removing wheel 52 during the entire rotation process, it is judged whether the installation positions of the first tape removing wheel 51 and the second tape removing wheel 52 are accurate, avoiding the problem that the installation position is deviated and is not conducive to the subsequent tape removing operation.

[0063] A second cylindrical gear 221 is fixedly sleeved on the second drive shaft 22. A first drive shaft 21 is rotatably connected to the frame 2. A first cylindrical gear 211 is fixedly sleeved on the first drive shaft 21. The diameter of the first cylindrical gear 211 is smaller than the diameter of the second cylindrical gear 221. The first cylindrical gear 211 and the second cylindrical gear 221 are meshed. The first drive shaft 21 is driven by a drive motor.

[0064] By setting the meshing of the first cylindrical gear 211 and the second cylindrical gear 221, and the diameter of the first cylindrical gear 211 is smaller than the diameter of the second cylindrical gear 221, the deceleration of the second drive shaft 22 can be realized, and then it is convenient for the first tape removing wheel 51 to rotate at a reduced speed, facilitating the tape removing operation of the diode tape.

[0065] The frame 2 is placed on the base 1 and fixed to the base 1 through a connecting block 4. A cavity for placing a material receiving box is formed between the frame 2 and the ground through the base 1, thus facilitating the material receiving operation of the disassembled diodes 7.

[0066] A guiding mechanism 3 is installed at one end of the connecting block 4 away from the frame 2. A first limiting roller 31 and a second limiting roller 32 are installed on the guiding mechanism 3. The second limiting roller 32 is located directly above the first limiting roller 31, and a positioning gap is formed between the second limiting roller 32 and the first limiting roller 31 for limiting during the traction process of the diode tape;

[0067] The first limiting roller 31 is rotatably connected to the guiding mechanism 3 through a first rotating rod. The second limiting roller 32 is rotatably connected to the guiding mechanism 3 through a second rotating rod.

[0068] Specifically, two symmetrically arranged lifting blocks 23 are installed on the frame 2. Each lifting block 23 is in an L shape and corresponds to the second tape removing wheel 52 one by one;

[0069] During tape removal, the red tape 8 and the white tape 9 on the diode tape slide along the surfaces of the corresponding lifting blocks 23 respectively;

[0070] The sliding surfaces for the red tape 8 and the white tape 9 on each lifting block 23 are consistent with the highest point of the first tape removing wheel 51.

[0071] By setting two L-shaped lifting blocks 23, the diode tape during the traction process is limited by the lifting blocks 23, so that the diodes 7, red tapes 8 and white tapes 9 on the diode tape can be pulled along the lifting blocks 23 to the corresponding tape removing wheels 51 and 52, meeting the requirements of subsequent tape removing work.

[0072] During operation, one end of the diode tape in the material box passes through the positioning gap formed on the guiding mechanism 3, and the red tape 8 and white tape 9 on the diode tape passing through the positioning gap are pulled by the traction mechanism on the tape removing device. The cooperation between the traction mechanism on the tape removing device and the tape removing mechanism 5 for traction and tape removal is prior art and will not be elaborated here. During the traction process, the diodes 7 on the diode tape are separated from the diode tape under the action of the tape removing mechanism 5 and the arc structure, and slide down along the arc end of the arc plate 6 on the arc structure into the receiving box for collection, completing the tape removing operation of the diode tape;

[0073] Specifically, when the tape removing mechanism 5 and the arc structure cooperate for tape removal, the red tape 8 and white tape 9 on the diode tape are respectively located on the corresponding lifting blocks 23, and under the action of the traction mechanism, the diode 7 is driven to be located in the corresponding positioning grooves 511 and 521. The red tape 8 and white tape 9 are respectively located on the corresponding tape removing wheels 52. The diode 7 located in the corresponding positioning grooves 511 and 521 approaches the arc structure as the tape removing wheel 51 rotates, and the separation of the diode 7 from the red tape 8 and white tape 9 and its falling into the receiving box are realized through the blocking of the arc structure. Since the red tape 8 and white tape 9 on both sides of the diode 7 are not blocked by the arc structure, the red tape 8 and white tape 9 are both continuously pulled outward by the traction mechanism to complete the tape removing operation.

[0074] It should be noted that the distance between the two tape removing wheels 51 is greater than the length of the thicker tube body in the middle of the diode 7. During tape removal, the thicker tube body of the diode is suspended between the two tape removing wheels 51;

[0075] And when the diode tape is placed, the side with the diode 7 on the diode tape faces downward and is close to the tape removing mechanism 5.

[0076] In summary, compared with the prior art, the following beneficial effects are achieved:

[0077] 1. By setting the arc structure, when setting the arc plate 6, the lowest end of the arc end of the arc plate 6 is lower than the lowest end of the tape removing wheel 51. When controlling the tape removal of the diode 7 on the diode tape, the diode 7 disassembled from the diode tape slides along the arc end and falls into the receiving box for collection, reducing the height of the free fall of the diode 7, thereby reducing the impact force on the diode 7 that has already fallen into the collection box and preventing the problem of damage to the diode 7.

[0078] 2. When setting the arc structure, two arc plates 6 are set, and the distance formed between the two arc plates 6 is used to limit the thicker tube body in the middle of the diode 7. The thicker tube body in the middle of the diode 7 slides along the gap. While realizing the sliding limit of the diode 7, the contact between the thicker tube body in the middle of the diode 7 and the arc structure is effectively reduced, further protecting the diode 7 after disassembly.

[0079] 3. By setting the limit post 531, the limit post 531 and the second limiting structure 532 are used to further fix the two first tape removing wheels 51, strengthening the stability of the two first tape removing wheels 51 during rotation. Furthermore, it can effectively reduce the deviation of the two first tape removing wheels 51 after long-term rotation, preventing the problem of inconvenient tape removal caused by the diode 7 not being accurately located in the corresponding first positioning groove 511 and the corresponding second positioning groove 521.

[0080] And the limit post 531 plays a warning role in whether the first tape removing wheel 51 and the second tape removing wheel 52 deviate, and can timely detect the problem of deviation of the second tape removing wheel 52.

[0081] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.
