Description

Technical Field

[0001] The invention belongs to the field of automation equipment, and in particular relates to an adhesive tape recycling mechanism and an adhesive peeling machine. Background Art

[0002] After the PCBA board is manufactured, it is necessary to test the parameters. Therefore, during the manufacturing process, it is necessary to stick adhesive tape on the test points on the PCBA board to prevent the three-proof paint from covering the test points during the manufacturing process and affecting the performance test of the PCBA. Then, the adhesive tape is torn off before the test to perform the PCBA board performance test. The existing adhesive tape is torn off and recycled by sticking it on the material to which the adhesive tape can be attached to avoid the adhesive tape falling randomly and polluting the environment. The material is placed on the unloading wheel and one end is rolled on the rewinding wheel. The process of unloading and rewinding the material makes the adhesive tape attached to the material to achieve the recycling of the adhesive tape. Therefore, in order to facilitate the calculation of the use of materials so that the materials can be replaced in time to realize the continuous production of automation, it is necessary to detect the use of materials, that is, to continuously detect the use of materials during the production process. The existing common practice is to use a transmission wheel to transmit the material and detect the number of rotations of the transmission wheel to calculate the moving length of the material and drive the rewinding wheel to rotate to rewind the material. However, this method is to independently drive the transmission wheel and the rewinding wheel separately, which has the following disadvantages:

[0003] (1) An additional drive device is required, which has a complex structure, occupies a large space, and increases the cost;

[0004] (2) After the receiving wheel reels a certain amount of material, the diameter of the material wrapped around the receiving wheel keeps increasing. Therefore, it is necessary to control the rotation speed of the receiving wheel according to the diameter of the material. That is, the speed of the receiving wheel keeps changing after the receiving wheel starts to reel in the material, which makes the control complex and difficult.

[0005] (3) After changing materials of different thicknesses, the control program needs to be reset, which has poor compatibility. If the control parameters are not changed in time, production failures are likely to occur. Summary of the invention

[0055] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0056] The invention realizes the transmission of materials by arranging the cooperation of the material transmission wheel and the material pressing assembly, and the material receiving wheel is driven to rotate by the first transmission belt when the material transmission wheel rotates, which can reduce a set of driving devices, simplify the structure and reduce costs. The surface of one side of the first transmission belt that contacts with the material transmission wheel and the material receiving wheel is a convex arc structure, so that the first transmission belt and the material transmission wheel, the first transmission belt and the material receiving wheel will not be stuck when the material receiving wheel is subjected to a certain external force, so that the first transmission belt and the material transmission wheel or the first transmission belt and the material receiving wheel can stop rotating when the material transmission wheel rotates, so that the material receiving wheel will not drive the material receiving wheel to continue rotating when the material transmission wheel rotates, so that when the material receiving wheel is driven to rotate next time, enough material can be wound up by the material receiving wheel to avoid the material being torn off and causing production failure. The transmission force between the first transmission belt and the material transmission wheel or between the material receiving wheels is less than the abutment force between the pressure assembly and the material transmission wheel, which can ensure that when the material pulls the material receiving wheel, the material between the pressure assembly and the material transmission wheel will not slip, resulting in inaccurate material length measurement.

[0057] Embodiment 1

[0058] See also Figure 1-2 An embodiment of the present invention provides a rubber tape recycling mechanism, including a support plate 10, a discharge wheel 20, a collection wheel 30, a transfer wheel 40, a pressing assembly 50, a first driving member 60 and a first transmission belt 70. Among them, the unloading wheel 20 and the receiving wheel 30 are rotatably arranged on one side of the support plate 10, and the unloading wheel 20 and the receiving wheel 30 are used for unloading and winding the material 2000, the feeding wheel 40 and the pressing assembly 50 are fixed to the support plate 10 and are located between the unloading wheel 20 and the receiving wheel 30, and the pressing assembly 50 abuts against the feeding wheel 40, and the first driving member 60 is arranged on the support plate 10 and drives the feeding wheel 40 to rotate, and the first transmission belt 70 is sleeved on the feeding wheel 40 and the receiving wheel 30 so that the first transmission belt 70 drives the feeding wheel 40 and the receiving wheel 30 to rotate, and the surface of the first transmission belt 70 on one side in contact with the feeding wheel 40 and the receiving wheel 30 is a convex arc structure, and the friction between the first transmission belt 70 and the feeding wheel 40 or between the first transmission belt 70 and the receiving wheel 30 is less than the friction formed by the pressing assembly 50 and the feeding wheel 40 when they abut against the material.

[0059] The adhesive tape recycling mechanism provided in the embodiment of the present invention is used to recycle the adhesive tape torn off from the product. When in use, a material 2000 is placed on the discharge wheel 20, and the material 2000 is an adhesive tape attachment member to which the adhesive tape can be attached, and the adhesive tape attachment member can be but is not limited to one of an adhesive tape and a masking adhesive, and then one end of the material 2000 placed on the discharge wheel 20 is passed through between the pressing wheel and the pressing assembly 50 and then wound onto the receiving wheel 30, and the first driving member 60 drives the feeding wheel 40 to rotate through the second transmission belt 80, and the feeding wheel 40 drives the receiving wheel 30 to rotate through the first transmission belt 70, thereby realizing the discharge and collection of the material 2000.

[0060] The cooperation between the feeding wheel 40 and the pressing assembly 50 realizes the transmission of the material 2000. The first driving member 60 directly drives the feeding wheel 40 to rotate, so that the use length of the material 2000 can be calculated by counting the number of rotations of the feeding wheel 40, and the first transmission belt 70 is used to drive the receiving wheel 30 to rotate when the feeding wheel 40 rotates, which can reduce a set of driving devices, simplify the structure and reduce costs. The surface of the first transmission belt 70 on one side that contacts the feeding wheel 40 and the receiving wheel 30 is a convex arc structure, so that the first transmission belt 70 and the feeding wheel 40, and the first transmission belt 70 and the receiving wheel 30 will not get stuck. When the receiving wheel 30 is subjected to a certain external force (that is, when the receiving wheel 30 is winding more and more material 2000, the rotation speed of the receiving wheel 30 remains unchanged, resulting in a longer length of the material 2000 wound when the receiving wheel 30 rotates at the same angle). The material 2000 is pulled by the receiving wheel 30 when the receiving wheel 30 is driven by the material 2000, and the material 2000 is pulled by the material 2000. This can cause the first transmission belt 70 and the feeding wheel 40 or the first transmission belt 70 and the receiving wheel 30 to slip, so that the receiving wheel 30 can stop rotating when the feeding wheel 40 rotates, so that the feeding wheel 40 will not drive the receiving wheel 30 to continue rotating when it rotates, so that when the receiving wheel 30 is driven to rotate next time, enough material 2000 can be wound up by the receiving wheel 30 to avoid the material 2000 being torn off and causing production failure. The transmission force between the first transmission belt 70 and the feeding wheel 40 or between the receiving wheels 30 is less than the contact force between the pressure assembly and the feeding wheel 40, which can ensure that when the material 2000 pulls the receiving wheel 30, the material 2000 between the pressing assembly 50 and the feeding wheel 40 will not slip, resulting in inaccurate length measurement of the material 2000.

[0061] The adhesive tape recycling mechanism provided by the present invention can use a set of driving devices to simultaneously drive the material transfer wheel 40 and the material receiving wheel 30, thereby saving space and cost, and at the same time, the control is simple and the product compatibility is strong.

[0062] In this embodiment, in order to reasonably arrange the positions of the first driving member 60 and the material transfer wheel 40 and facilitate the linkage between the first driving member 60 and the material transfer wheel 40, a second transmission belt 80 can be provided to sleeve the driving end of the first driving member 60 and the material transfer wheel 40. Further, the second transmission belt 80 is a flat belt, the inner wall of the second transmission belt 80 is provided with teeth, and correspondingly, the driving end of the first driving member 60 is provided with a first gear 601 meshed with the second transmission belt 80, and the end of the rotating shaft of the material transfer wheel 40 passing through the support plate 10 is provided with a second gear 401 meshed with the second transmission belt 80, so as to avoid slippage between the first driving member 60 and the second transmission belt 80, and between the material transfer wheel 40 and the second transmission belt 80; or the second transmission belt 80 is a V-belt, and the driving end of the first driving member 60 and the end of the rotating shaft of the material transfer wheel 40 passing through the support plate 10 are respectively provided with driving wheels that cooperate with the V-belt, and the V-belt can increase the friction with the driving wheel and get stuck with the contact surface between the driving wheel, which can also avoid slippage.

[0063] In this embodiment, in order to avoid interference, the second transmission belt 80 and the first transmission belt 70 are arranged on the side of the support plate 10 away from the material transfer wheel 40 and the material receiving wheel 30, and the rotating shafts of the material transfer wheel 40 and the material receiving wheel 30 pass through the support plate 10 to facilitate the installation of the second transmission belt 80 and the first transmission belt 70.

[0064] In this embodiment, the first transmission belt 70 may be, but is not limited to, a round belt, and the first driving member 60 may be a motor.

[0065] Embodiment 2

[0066] On the basis of the first embodiment, the transmission ratio of the material transfer wheel 40 and the material receiving wheel 30 is 1:1, and the diameter of the position where the material transfer wheel 40 abuts against the material pressing assembly 50 is equal to the diameter of the part of the material receiving wheel 30 that wraps around the material 2000. In this way, when the transmission ratio of the material transfer wheel 40 and the material receiving wheel 30 is 1:1, when the material transfer wheel 40 makes one circle at the beginning, the material receiving wheel 30 also makes one circle. As the material receiving wheel 30 receives more material, the second transmission belt 80 starts to slip, and the first transmission belt 70 has the shortest slip time and the least slip times, which can improve the service life of the first transmission belt 70 and make the adhesive tape recovery mechanism work more reliably. If the solution is adopted in which the diameter of the material transfer wheel 40 is smaller than the diameter of the material receiving wheel 30, the material receiving wheel 30 will not make more than one circle when the material transfer wheel 40 makes one circle, and the material receiving wheel 30 will not reach the material receiving effect; if the solution is adopted in which the diameter of the material transfer wheel 40 is larger than the diameter of the material receiving wheel 30, the material receiving wheel 30 will rotate more than one circle when the material transfer wheel 40 makes one circle, and therefore, slipping will occur at the beginning, resulting in too high a slipping frequency, which will affect the service life of the first transmission belt 70.

[0067] It should be noted that the "diameter of the transfer wheel 40" mentioned above refers to the aforementioned "diameter of the abutment position between the transfer wheel 40 and the pressure assembly", and the "diameter of the receiving wheel 30" refers to the aforementioned "diameter of the part of the receiving wheel 30 that wraps around the material 2000".

[0068] Embodiment 3

[0069] See also Figure 3 On the basis of the first or second embodiment, further, the pressing assembly 50 includes a first fixing member 501 , a rotating arm 502 , a roller 503 , an adjusting member 504 and a first elastic member 505 . Among them, the first fixing member 501 is arranged on the support plate 10 and is located on one side of the material transfer wheel 40, the rotating arm 502 is hinged to the first fixing member 501, the roller 503 is arranged on the rotating arm 502 and abuts against the material transfer wheel 40 to form a material 2000 transmission station, the adjusting member 504 is adjustably arranged on the first fixing member 501 and the rotating arm 502 is passed through one end, and the adjusting member 504 passes through the rotating arm 502. One end is provided with a limiting portion 5041 abutting against the rotating arm 502, and the rotating arm 502 can rotate toward the adjusting member 504, that is, the adjusting member 504 can pull the rotating arm 502 through the limiting portion 5041 to drive the roller 503 to rotate away from the material transfer wheel 40 to reduce the abutment force between the roller 503 and the material transfer wheel 40, and the first elastic member 505 is arranged between the first fixing member 501 and the rotating arm 502 and provides the roller 503 with a pre-tightening force to abut against the material transfer wheel 40.

[0070] The distance between the limit portion 5041 of the adjusting member 504 and the transfer wheel 40 limits the contact force between the roller 503 and the transfer wheel 40. By adjusting the distance between the limit portion 5041 and the transfer wheel 40, that is, moving the adjusting member 504 closer to or away from the transfer wheel 40, the contact force between the roller 503 and the transfer wheel 40 can be adjusted to ensure that the contact force between the pressure assembly and the transfer wheel 40 is always greater than the transmission force between the first transmission belt 70 and the transfer wheel 40 or between the first transmission belt 70 and the receiving wheel 30. The first elastic member 505 can ensure that the roller 503 is always in contact with the transfer wheel 40 to realize the transmission of the material 2000.

[0086] See also Figure 7 Furthermore, a convex rib 51 is provided on one side of the clamping jaw 5 abutting against the support platform 4, and a groove 41 is provided on one side of the support platform 4 abutting against the clamping jaw 5. When the clamping jaw 5 abuts against the surface of the support platform 4, the convex rib 51 is embedded in the groove 41. The convex rib 51 cooperates with the groove 41 to improve the clamping stability of the clamping jaw 5 and the support platform 4 on the adhesive tape, thereby preventing the adhesive tape from being unstably clamped and causing a tearing failure.

[0087] See also Figure 6 Furthermore, the glue peeling mechanism further includes a first push rod 7, a second push rod 8 and a second elastic member 9. The first push rod 7 is arranged at one side of the support platform 4 and is driven to move by the fourth driving member 6, one end of the second push rod 8 is telescopically connected to the first push rod 7, and the other end is connected to the clamping claw 5, and the second elastic member 9 is arranged between the first push rod 7 and the second push rod 8 and provides a pre-tightening force to the second push rod 8 to move away from the first push rod 7. The first push rod 7 and the second push rod 8 are telescopically connected and a second elastic member 9 is arranged therebetween. When the fourth driving member 6 drives the clamping jaw 5 to rotate, the clamping jaw 5 can push the second push rod 8 in the opposite direction to squeeze the second elastic member 9, thereby ensuring a buffer contact between the clamping jaw 5 and the support platform 4. On the one hand, it can avoid that the driving force of the fourth driving member 6 is not good at controlling the abutting force between the clamping jaw 5 and the support platform 4, resulting in hard contact between the two and easy wear, so as to ensure the clamping stability of the clamping jaw 5 and the support platform 4 on the adhesive tape. On the other hand, the clamping gap between the clamping jaw 5 and the support platform 4 can be adjusted according to the thickness of the adhesive tape. The second elastic member 9 can ensure that the first push rod 7 and the second push rod 8 are in a tensioned state in the direction of moving away from each other, so as to ensure that the second driving cylinder can better drive the clamping jaw 5 to rotate.

[0088] Specifically, a step 71 is provided on the outside of the first push rod 7, the second push rod 8 is a hollow structure, the first push rod 7 is embedded in the second push rod 8, the second elastic member 9 is sleeved on the first push rod 7 and the two ends are respectively abutted against the step 71 and the end of the second push rod 8 to facilitate the installation of the second elastic member 9.

[0089] In this embodiment, the second elastic member 9 may be, but is not limited to, a coil spring.

[0090] Specifically, a through slot 81 is provided on the side wall of the second push rod 8, and the through slot 81 extends along the axis of the second push rod 8. A positioning pin 72 is provided on the first push rod 7 and can move in the through slot 81. The positioning pin 72 abuts against an end of the through slot 81 away from the clamping jaw 5. The cooperation between the positioning pin 72 and the through slot 81 can prevent the first push rod 7 from being separated from the second push rod 8, thereby realizing the connection between the first push rod 7 and the second push rod 8.

[0091] Specifically, the fourth driving member 6 is a cylinder, the piston of the cylinder is fixed to the moving member 2 to achieve the fixation of the fourth driving member 6, the first push rod 7 can be movably passed through the moving member 2 and connected to the cylinder body of the cylinder, when the cylinder moves, the movement of the cylinder body relative to the piston rod can drive the first push rod 7 to move.

[0092] In this embodiment, when the number of the clamping jaws 5 is 4, a mounting plate 61 can be set on the cylinder body. The mounting plate 61 can not only facilitate the installation of the first push rod 7, but also increase the area of ​​the cylinder body so that multiple first push rods 7 can be fixed on the mounting plate 61 at the same time, so that one cylinder can drive multiple clamping jaws 5 to save space and cost.

[0093] See also Figure 7 Further, one end of the clamping jaw 5 connected to the fourth driving member 6 is hinged with a connecting rod 52, and the end of the connecting rod 52 away from the clamping jaw 5 is hinged with the fourth driving member 6. That is, the connecting rod 52 is hinged with the clamping jaw 5 and the second push rod 8 respectively, so that the three form a connecting rod 52 structure, thereby realizing the conversion of the linear motion of the fourth driving member 6 into the rotational motion of the clamping jaw 5.

[0094] See also Fig.13 Furthermore, a vacuum suction hole 1002 is provided on one side of the support platform 100 facing the material 2000. The vacuum suction hole 1002 can firmly adsorb the material 2000 on the support platform 100, and can prevent the material 2000 from being taken away from the support platform 100 when the adhesive tape is attached to the material 2000 by the adhesive tape peeling mechanism 900 and then removed from the material 2000. During operation, the vacuum suction hole 1002 is connected to a vacuum pump (not shown in the figure). When the material 2000 stops being conveyed and before the adhesive tape peeling mechanism 900 peels off the adhesive tape from the product and attaches it to the material 2000, the vacuum pump is controlled to firmly adsorb the material 2000 on the support platform 1000 through the vacuum suction hole 1002. After the adhesive tape peeling mechanism 900 attaches the adhesive tape to the material 2000 and leaves, the vacuum pump is controlled to release the material 2000, so that the material 2000 can be conveyed by the material transfer wheel 40.

[0095] In this embodiment, the glue tearing mechanism 900 can be set according to whether the adhesive tape on the product is pasted on one side or on two opposite sides. For example, when the adhesive tape of the product is pasted on one side, the glue tearing mechanism 900 can be set only on one side of the transmission direction of the material 2000. When the adhesive tape of the product is set on two opposite sides, the glue tearing mechanism 900 can be set on two opposite sides of the transmission direction of the material 2000. At this time, an avoidance groove 1001 can be set on the supporting platform 100. The avoidance groove 1001 is located next to the material 2000. The glue tearing mechanism 900 can be installed in this avoidance groove 1001 so that the glue tearing mechanism 900 can extend normally toward the product to tear off the adhesive tape.

[0096] Embodiment 6

[0097] See also Fig. 9 On the basis of the fifth embodiment, the adhesive tape recovery mechanism further includes a paper pressing mechanism 200, which is arranged on the support plate 10 and located on the same side of the adhesive peeling mechanism 900. The paper pressing mechanism 200 includes a pressing block 2001 rotatably arranged on the support plate 10, and the pressing block 2001 can rotate toward the supporting platform 100 and abut against the supporting platform 100. When the pressing block 2001 abuts against the supporting platform 100, the pressing block 2001 presses on the adhesive tape torn off by the adhesive peeling mechanism 900. When the adhesive peeling mechanism 900 tears off the adhesive tape, moves the adhesive tape to the supporting platform 100, and presses the adhesive tape on the supporting platform 100 so that the adhesive tape is attached to the material 2000, the adhesive tape cannot be firmly attached to the material 2000. By pressing the pressing block 2001 on the adhesive tape, it is easy for the adhesive tape to be separated from the adhesive peeling mechanism 900 and firmly attached to the material 2000.

[0098] See also Fig.10 Furthermore, a protrusion 2001a is provided on one side of the pressing block 2001 abutting against the supporting platform 100. The protrusion 2001a can reduce the contact area between the pressing block 2001 and the adhesive tape, thereby preventing the pressing block 2001 from taking the adhesive tape away from the material 2000 when leaving the material 2000.

[0099] Specifically, the paper pressing mechanism 200 further includes a second fixing member 2002 and a second driving member 2003. The second fixing member 2002 is fixed to the support plate to fix the pressing block 2001. The pressing block 2001 is hinged to the second fixing member 2002 so that the pressing block 2001 can rotate relative to the second fixing member 2002. The second driving member 2003 is fixed to the second fixing member 2002 and drives the pressing block 2001 to rotate toward the supporting platform 100. In this embodiment, the second driving member 2003 can be, but is not limited to, a cylinder.

[0100] Specifically, the middle portion of the pressing block 2001 is hinged to the second fixing member 2002 , and one end of the second driving member 2003 drives the side of the pressing block 2001 away from the supporting platform 100 so that the pressing block 2001 can rotate toward the supporting platform 100 .

[0101] In this embodiment, when there are multiple sets of glue peeling mechanisms 900, multiple sets of paper pressing mechanisms 200 are also provided to correspond to the glue peeling mechanisms 900. When the paper pressing mechanisms 200 are also provided on opposite sides of the transmission direction of the material 2000, the paper pressing mechanisms 200 can be evenly arranged around the supporting platform 100, that is, the paper pressing mechanisms 200 do not need to penetrate the supporting platform 100, and the adhesive tape torn off by the glue peeling mechanism 900 can be pressed onto the material 2000 on the supporting platform 100 by only partially extending the pressing block 2001 into the supporting platform 100.
