Description

Sticky tape remove device of touch pad

Technical Field

The invention relates to the technical field of nonstandard automation equipment, in particular to an adhesive tape removing device for a touch pad.

Background

A touch pad (TouchPad or TrackPad) is an input device widely used in notebook computers. The touch pad senses the movement of a user finger by using the detection principle of capacitance sensing to control the action of a pointer. A special integrated circuit board under the touch pad surface constantly measures and reports this trace to ascertain finger motion and position. When the mouse cursor is operated using the touch pad, the mouse cursor is positioned on a corresponding item or icon, and the corresponding item or icon is selected by tapping the touch pad.

The touch pad comprises a touch panel, a circuit board and a bottom plate, wherein the touch panel is fixed with the top surface of the circuit board, and the local area of the bottom surface of the circuit board is fixed on the bottom plate through an adhesive layer. When a user presses the touch panel, the touch panel and the circuit board can swing by taking the part of the adhesive layer as an axis.

Generally, the bonding molding of the touch panel is usually performed by a touch panel clamping jig. The touch pad clamping jig comprises a bearing part and a pressing cover part. The pressing cover part can be freely separated and buckled relative to the bearing part along the vertical direction. In the actual operation process, the base plate is firstly placed on the bearing part, then the glue layer is coated on the base plate, then the assembled touch panel and the circuit board are integrally attached to the base plate, finally the pressing cover part is buckled on the bearing part, and standing is carried out for a period of time, so that the pressure-bearing circuit board and the base plate are firmly bonded.

In the prior art, after the assembled touch panel and the circuit board are pasted on the touch panel bottom plate as a whole, the pressing cover part of the touch panel clamping jig is formally buckled in front of the bearing part, and the touch panel to be bonded needs to be fixed by means of an adhesive tape so as to avoid dislocation caused by pressure bearing subsequently. Before glue is completely solidified (enough binding force is provided between the binding layers of the touch pad pre-bound at the moment so as to resist lateral dislocation force), a production line worker needs to tear off the initial positioning adhesive tape in time, and in the prior art, the adhesive tape is torn off by means of an auxiliary adhesive tape removing device, for example, a Chinese patent CN112919040B discloses an auxiliary adhesive tape removing device, and the auxiliary adhesive tape removing device pushes the touch pad clamping jig running to an auxiliary adhesive tape removing station to be completely separated from a belt conveyor, so that the production line worker can execute subsequent positioning adhesive tape tearing operation. However, the automation degree of the production line is still not high enough, the tearing operation of the adhesive tape is still completed manually, the operation mode is time-consuming and labor-consuming, the labor intensity of workers is high, the production efficiency is low, and the operation workers are easily injured and other safety accidents are easily caused. Therefore, a skilled person is urgently required to solve the above problems.

Detailed Description

Example (b):

as shown in fig. 1 to 8, a tape removing apparatus for a touch panel 10 according to an embodiment of the present invention includes a housing, a mounting substrate 1, at least one set of tape tearing assemblies 2, a lifting assembly 3, a sliding assembly 4, and a touch panel 6. As shown in fig. 3, in the embodiment of the present invention, the mounting substrate 1 is a hexagonal flat plate.

For convenience of description and distinction, the direction of the curing line of the touch panel is expressed as a left-to-right direction as shown in fig. 7 as a first direction, and the direction of the sliding member 4 is expressed as an up-down direction as shown in fig. 7 as a second direction, in the embodiment of the present invention, the length direction of the touch panel 10 is parallel to the second direction, the width direction of the touch panel 10 is parallel to the first direction, the movement direction of the second linear movement of the first tape tearing mechanism 21 is parallel to the second direction, and the movement direction of the second linear movement of the second tape tearing mechanism 22 is parallel to the first direction.

Wherein, as shown in fig. 7 and 8, the frame body comprises two support frames which are opposite from left to right, are spaced in parallel and extend along the up-down direction, namely the second direction, the lower end bottoms of the two support frames are respectively provided with a support leg 7, and the upper end bottoms of the two support frames are provided with a square frame-shaped support frame 9. The top of two support frames is equipped with sliding assembly 4, is formed with between two support frames and dodges the space, should dodge the space and divide into two districts, and one of them district is the region of operation area also being the below of two supporting legs 7, and the operation area is close to touch pad solidification line, and another is the waste material district also is the region at braced frame 9 top, and touch pad solidification line is kept away from in the waste material district. In order to facilitate the subsequent adhesive tape tearing operation of the touch panel 10 after the adhesive tape tearing operation is completed, an adhesive tape collecting device 5 is fixed on the waste material area, namely the supporting frame 9, and after the adhesive tape on the previous touch panel 10 is torn by the adhesive tape removing device, the adhesive tape tearing assembly 2 is driven by the sliding assembly 4 to be moved to the waste material area from the operation area, so that the torn adhesive tape is thrown into the adhesive tape collecting device 5 by the operation area and then driven by the sliding assembly 4 to be moved to the operation area from the waste material area to carry out the adhesive tape tearing operation of the next touch panel 10.

As for the sliding assembly 4, as shown in fig. 7, the sliding assembly 4 includes two sliding rails 41 fixed on two supporting frames one by one, two sliding blocks 42 sliding fitted on the two sliding rails 41 one by one, and a sliding driving member 43 (in the embodiment of the present invention, a rodless cylinder is preferably used) fixed on one of the supporting frames for driving one of the sliding blocks 42 to slide along its corresponding sliding rail 41 and driving the other sliding block to slide along its corresponding sliding rail, so as to drive the whole tape tearing assembly to move, wherein the sliding rails 41 extend along the second direction. In the two slide rails 41 of the embodiment of the present invention, the slide rail 41 provided with the slide driving member 43 is an electric slide rail, and the other slide rail 41 is a common slide rail. As an alternative embodiment, the two slide rails may be provided with a slide driving member 43.

As for the tape collecting device 5, as shown in fig. 7 and 8, the tape collecting device 5 includes a square waste collection box 51 disposed at the top end of the supporting frame 9 and having an open top, and an ion wind bar 52 disposed around the open top of the waste collection box 51, and since the tape is light in weight and easily adheres to the side wall due to its stickiness, the ion wind bar 52 is designed to prevent the torn tape from adhering to the side wall of the waste collection box 51 when thrown into the waste collection box 51 by the arrangement of the ion wind bar 52.

According to some embodiments of the present invention, as shown in fig. 3, the tape removing assembly 2 includes two sets, each set of tape removing assembly 2 includes one first tape removing mechanism 21 and one second tape removing mechanism 22, that is, the tape removing assembly 2 of this embodiment includes two first tape removing mechanisms 21 and two second tape removing mechanisms 22. The two groups of adhesive tape tearing assemblies 2 are sequentially distributed along the circumferential direction of the bottom of the mounting substrate 1, that is, the two first adhesive tape tearing mechanisms 21 and the two second adhesive tape tearing mechanisms 22 are circumferentially spaced and alternately arranged at the bottom of the mounting substrate 1. Because the touch pad 10 is square, has two long limits and two minor faces, two long limits and two minor faces all have a plurality ofly to wait to tear off sticky tape 100 and usually be three, and the adjacent interval of waiting to tear off between sticky tape 100 on long limit and the minor face is different, so need set up two sets of sticky tapes and tear off subassembly 2 with two long limits that just in time correspond touch pad 10 and two waiting to tear off sticky tape 100 on the minor face. As an alternative embodiment, the tape removing assembly 2 of the present invention may also include only one set, that is, only one first tape removing mechanism 21 and one second tape removing mechanism 22, in this case, the rotation of the tape removing assembly 2 or the rotation of the touchpad clamping fixture or the manual rotation of the touchpad 10 may be performed, but since an additional rotation mechanism or a manual rotation operation is required to control the rotation of the tape removing assembly 2 or the touchpad 10, so as to remove all the tapes on four sides of the touchpad 10. Therefore, the embodiment of the present invention preferably employs two sets of tape tearing assemblies 2, which correspond to the removal operations of the to-be-torn tapes 100 on the two long sides and the two short sides of the touch panel 10, and complete the removal of all the to-be-torn tapes 100 at one time. It should be noted that the adhesive tape tearing assembly 2 of the embodiment of the present invention may also be arranged in other groups, such as three groups, four groups, etc., at intervals along the circumferential direction, which depends mainly on the shape of the object to be processed (in the embodiment, the square touch pad).

According to some preferred embodiments of the present invention, each of the first tape tearing mechanism 21 and the second tape tearing mechanism 22 includes three clamping members 211, a rotating member 214, a first linear motion member 212, and a second linear motion member 213. For any adhesive tape removing mechanism, the clamping component 211, the rotary lifting component 214, the second linear motion mechanism 213 and the first linear motion mechanism 212 are arranged in sequence from top to bottom. Because the distance between the adjacent tapes 100 to be torn off on the long side and the short side of the touch pad 10 is different, the three clamping and placing components 211 of the first tape tearing mechanism 21 are different from the three clamping and placing components 211 of the second tape tearing mechanism 22 in distance, and because the first tape tearing mechanism 21 corresponds to the long side of the touch pad 10 and the second tape tearing mechanism 22 corresponds to the short side of the touch pad 10, the distance between every two three clamping and placing components 211 of the first tape tearing mechanism 21 is larger than the three clamping and placing components 211 of the second tape tearing mechanism 22. It should be noted that the three clamping assemblies 211 of the first tape tearing mechanism 21 and the three clamping assemblies of the second tape tearing mechanism 22 are identical in structure, and the other components of the two tape tearing mechanisms, including the lifting assembly 214, the first linear motion mechanism 212 and the second linear motion mechanism 213, are identical in structure. Therefore, only one of the first tape removing mechanism 21 or the second tape removing mechanism 22 will be described below. The first adhesive tape tearing mechanism 21 is taken as an example for explanation in the embodiment of the present invention, as shown in fig. 4 and fig. 5, the three clamping and placing components 211 of the first adhesive tape tearing mechanism 21 are arranged in a straight line, and preferably, the distances between two adjacent clamping and placing components 211 are all equal, it should be noted that the distances between two clamping and placing components 211 are not limited to be equal, which is mainly determined based on the adhesive tape 100 to be torn on the touch pad 10, and the distances between two adhesive tapes 100 to be torn on each side edge of the general touch pad 10 are equal. The number of the clipping components 211 is not limited to the above-mentioned preferred three, and those skilled in the art can select the design according to the actual situation, such as one, two, four, etc., and the basic requirement is to correspond to the number of the tapes 100 to be torn off on the side of the touch pad 10. When the number of the clamping components 211 is designed to be one, since the moving direction of the second linear motion mechanism 213 is parallel to the direction of the lifting of the tape to be torn 100, that is, the direction of the corresponding side of the touch pad 10 corresponding to the first tape tearing mechanism 21, the tape to be torn 100 on the corresponding side of the touch pad 10 can be torn one by one only by linearly moving the second linear motion mechanism 213 to adjust the distance between the clamping components 211 and the tape to be torn 100.

Embodiments of the present invention are optional but not limited to pneumatic jaws that are conventional in the art with respect to the clamping assembly 211, and the specific structure and operation of the pneumatic jaws are not limited and described herein.

For the first linear motion mechanism 212 and the second linear motion mechanism 213, it is preferable to use the existing conventional slide cylinder in the embodiment of the present invention. In the embodiment of the present invention, as shown in fig. 4, a cylinder of the first linear motion mechanism 212 is disposed on the vertical mounting plate 20 at the bottom of the mounting substrate 1 through a second connecting seat 216, a driving end of the first linear motion mechanism 212 is specifically a driving rod connected to a third connecting seat 217, a cylinder of the second linear motion mechanism 213 is fixed to the third connecting seat 217, a driving end of the second linear motion mechanism 213 is specifically a driving rod connected to a first connecting seat 215, and the rotating-lifting assembly 214 is mounted on the first connecting seat 215. So that the whole tape tearing mechanism is spatially formed into a three-dimensional structure in which the first linear motion mechanism 212 is positioned at the lowest layer, the second linear motion mechanism 213 is positioned in the middle, the lifting component 214 is positioned above the second linear motion mechanism 213, and the clamping component 211 is positioned above the lifting component 214, and the design can greatly reduce the size of the whole tape tearing assembly 2. The telescopic direction of the driving rod of the first linear motion mechanism 212 and the direction of the surface of the touch pad 10 or the clamping jig of the touch pad 10 form an inclination angle not more than 90 degrees, the telescopic direction of the driving rod of the second linear motion mechanism 213 is parallel to the direction of the side edge of the touch pad 10 corresponding to the adhesive tape tearing mechanism, that is, the telescopic direction of the driving rod of the second linear motion mechanism 213 of the first adhesive tape tearing mechanism 21 is parallel to the long edge of the touch pad 10, and the telescopic direction of the driving rod of the second linear motion mechanism 213 of the second adhesive tape tearing mechanism 22 is parallel to the short edge of the touch pad 10, and since the adhesive tapes on the long edge and the short edge are distributed at intervals along the edge, the adhesive tape tearing action can be completed when the second linear motion mechanism 213 performs telescopic motion. It should be noted that the clamping and releasing component 211 protrudes outward from the mounting base of the lifting component 214, i.e. the first connecting seat 215, so as to ensure that when the first linear motion mechanism 212 operates to drive the second linear motion mechanism 213, the lifting component 214 and the clamping and releasing component 211 to synchronously approach the touch pad 10, the clamping and releasing component 211 first touches and clamps the adhesive tape 100 to be torn off so as to facilitate subsequent lifting and tearing off operations. It should be noted that the first linear motion mechanism 212 moves closer to the tape 100 to be removed when it is extended, and moves away from the touch panel 10 when it is retracted, so that the tape is completely separated from the touch panel 10. In the initial state, the second linear motion mechanism 213 is in the extended position, and the second linear motion mechanism 213 performs the tearing operation when retracted. Specifically, when the adhesive tape is torn off, the first linear motion mechanism 212 is firstly pulled out to drive the second linear motion mechanism 213, the rotary lifting component 214 and the clamping component 211 to be close to the touch pad synchronously, the clamping component 211 is firstly close to the adhesive tape 100 to be torn off and is started to clamp the adhesive tape 100 to be torn off, then the rotary lifting component 214 acts to lift one end of the adhesive tape 100 to be torn off upwards, then the second linear motion mechanism 213 backs to drive the clamping component 211 to move along the other side direction of the lifted adhesive tape 100 to be torn off to tear off the adhesive tape, and finally the first linear motion mechanism 212 backs to drive the clamping component 211 to be far away from the touch pad 10, so that the torn adhesive tape is completely separated from the touch pad 10 to complete the adhesive tape tearing off operation. The reset operation of the second linear motion mechanism 213 may be performed after the tearing operation is completed, or may be performed after the first linear motion mechanism 212 is reset, and is not particularly limited.

According to some preferred embodiments of the present invention, lift module 214 includes a telescoping drive mechanism, movable member 2142, and a transmission mechanism 2143. The telescopic driving mechanism includes a driving body 2141 fixedly mounted on the second linear motion mechanism 213 and a telescopic driving rod 21410 provided at a driving end of the driving body 2141. As shown in fig. 5, the telescopic driving mechanism is a conventional linear cylinder, that is, the driving body 2141 is a cylinder body of the linear cylinder, and the telescopic driving rod 21410 makes an extending or retracting movement in the left-right direction as shown in fig. 5, that is, in parallel with the direction of the withdrawing or retracting movement of the second linear movement mechanism 213, and more specifically, in parallel with the side direction of the touch pad 10 corresponding to the tape tearing mechanism. The movable member 2142 is connected to the end of the telescopic driving rod 21410 and is driven by the telescopic driving rod 21410 to move. The movable member 2142 in the embodiment of the present invention is a movable plate perpendicular to the axial direction of the telescopic driving rod 21410, or along the telescopic direction of the telescopic driving rod 21410. The transmission mechanism 2143 includes an active portion connected to the moving member 2142 and at least one passive portion connected to the active portion in a transmission manner and driven by the active portion to perform a synchronous motion, and the at least one passive portion is connected to the at least one clamping and releasing component 211 in a one-to-one correspondence manner. In the embodiment of the present invention, as shown in fig. 4 and 5, the transmission mechanism 2143 is preferably a rack-and-pinion transmission mechanism, and specifically, the driving portion is a rack 21431, and the driven portion is a pinion 21432. The rack 21431 extends along the telescopic direction, and three gears 21432 are meshed on the rack 21431 at intervals side by side, so that synchronous transmission is realized.
