Moreover, it should be understood that, although the terms first, second, etc. may be used herein to describe various elements or structures, these described objects should not be limited by the above terms. The above terms are used only to distinguish these descriptive objects from each other.
Referring to fig. 1 to 6, the present invention provides a braid peeling force testing device 100 for testing the peeling force between a carrier tape and a cover tape in a section of the braid pre-sealed by a preset sealing parameter before packaging an electronic component into the braid, so as to determine whether the preset sealing parameter is suitable. Thereby ensuring that the peel force of the braid is within a proper range after the electronic component is subsequently encapsulated into the braid.
Specifically, the pre-sealed braid includes a connecting section where the carrier tape is connected to the long side of the cover tape and a separate separating section.
The braid peeling force testing device 100 comprises a base 1, a first clamping component 2 arranged on the base 1, a second clamping component 3 arranged on the base 1 and opposite to the first clamping component 2 along a preset direction, a transplanting component 4 used for driving the second clamping component 3 to be close to or far away from the first clamping component 2 along the preset direction, a tension meter 5 and a control unit for controlling the braid peeling force testing device 100 to operate. One of the first clamping assembly 2 and the second clamping assembly 3 is connected with the transplanting assembly 4, the other is connected with the testing end of the tension meter 5, and the first clamping assembly 2, the second clamping assembly 3, the transplanting assembly 4 and the tension meter 5 are all in communication connection with the control unit. During testing, the head end of the carrier tape of the separation section in the braid to be tested is clamped in the first clamping assembly 2, the head end of the cover tape is clamped in the second clamping assembly 3, when the transplanting assembly 4 drives the second clamping assembly 3 to be far away from the first clamping assembly 2, the head end of the carrier tape and the head end of the cover tape are driven to be far away from each other, and when the head end of the carrier tape and the head end of the cover tape are far away from each other to the separation of the carrier tape and the cover tape in the connection section, the stripping force of the braid to be tested can be obtained through the tension meter 5. In the test process, the transplanting assembly 4 can control the first clamping assembly 2 and the second clamping assembly 3 to be relatively stably and uniformly far away, so that the carrier tape and the cover tape are relatively stably and uniformly far away/stripped, and the relatively accurate stripping force can be obtained; meanwhile, manual intervention in the braid stripping force test process is reduced, the cost is reduced, and the test efficiency is improved.
Specifically, the head end of the carrier tape and the head end of the cover tape refer to an end of a separation section adjacent to a connection section to be tested, which is far away from the connection section, that is, refer to a clamping end of the separation section to be clamped by the second clamping assembly 3 and the first clamping assembly 2.
In this embodiment, the preset direction is a vertical direction, specifically, the base body has a mounting surface extending along the vertical direction, the first clamping component 2 is mounted on the mounting surface, the second clamping component 3 is located above the first clamping component 2, and the first clamping component 2 and the second clamping component 3 are oppositely disposed along the vertical direction. Correspondingly, the transplanting assembly 4 is used for driving the second clamping assembly 3 to be close to or far away from the first clamping assembly 2 along the vertical direction, so that the carrier tape and the cover tape are pulled to be peeled along the vertical direction. Compared with the existing braid peeling force testing device for pulling the carrier tape and the cover tape to be separated along the horizontal direction, the braid peeling force testing device 100 can be reduced in occupied area by arranging the second clamping assembly 3 and the first clamping assembly 2 to be arranged along the vertical direction and relatively moving along the vertical direction, and the braid peeling force testing device 100 and the electronic element packaging equipment are combined.

When the preset direction is the vertical direction, the driving wheel and the driven wheel 42 are arranged at intervals along the vertical direction, the belt 43 extends along the vertical direction, and when the transplanting motor 41 is started to drive the belt 43 to drive, the first clamping assembly 2 is driven to move along the vertical direction so as to be close to or far away from the second clamping assembly 3.
Further, the transplanting assembly 4 further includes a guiding structure disposed between the fixing base 44 and the mounting surface, so as to guide the moving direction of the fixing base 44 relative to the mounting surface, and improve the stability of the braid peeling force testing device 100.

The clamping jaw air cylinder 32 is in communication connection with the control unit, and the clamping jaw air cylinder 32 controls the clamping jaw 33 to open or close, so that when the clamping jaw 33 is open, the head end of the cover tape can enter between the clamping jaws 33 or can be loosened, and when the clamping jaw 33 is closed, the clamping jaw 33 can clamp the head end of the cover tape so as to facilitate subsequent testing. Of course, this is not a limitation.
In an embodiment, as shown in fig. 2 and 4, the first clamping assembly 2 includes a pressing seat 21 connected to the fixing seat, a pressing cylinder 22 connected to the pressing seat 21, and a pressing plate 23 connected to an output end of the pressing cylinder 22, where the pressing cylinder 22 is connected to the control unit in a communication manner. The pressing plate 23 is driven to be close to or far away from the pressing seat 21 through the pressing cylinder 22, when a gap is reserved between the pressing plate 23 and the pressing seat 21, the head end of the braid/carrier tape can enter between the pressing plate 23 and the pressing seat 21, the pressing plate 23 is driven to press down by the pressing cylinder 22, and the pressing plate 23 and the pressing seat 21 are matched to clamp the head end of the braid/carrier tape.
Further, referring to fig. 1 to 3, the braid peeling force testing device 100 further includes a conveying assembly 6 disposed on the base 1 and opposite to the first clamping assembly 2 along a preset direction. The conveying assembly 6 comprises a conveying channel for conveying the braid to be tested and a pinch roller assembly 64 for driving the braid to be tested to move in the conveying channel. The conveying channel comprises a discharge hole which is opened towards the first clamping component 2, the pinch roller component 64 conveys the braid to be tested, and the braid to be tested is output and moved from the discharge hole to a position between the pressure seat 21 and the pressure plate 23. Therefore, the braid peeling force testing device 100 can automatically convey the braid to be tested, the automation of the braid peeling force testing device 100 is improved, the manual intervention is reduced, the efficiency is improved, and the cost is reduced.
In the embodiment where the preset direction is the vertical direction, the conveying assembly 6 is located above the first clamping assembly 2, and the discharge port is opposite to the first clamping assembly 2 and opens downward. Specifically, the conveying channel comprises a vertical channel 61 extending upwards from the discharge hole, a horizontal channel 62 extending along the horizontal direction, and a steering channel 63 communicating one end of the vertical channel 61 far away from the discharge hole with the horizontal channel 62, wherein a driving groove 621 is formed in a penetrating manner on one side of the horizontal channel 62 far away from the seat body 1, and the pinch roller assembly 64 drives the braid to be tested to move in the conveying channel from the driving groove 621.
Specifically, the pinch roller assembly 64 includes a cylinder fixed on the base 1, a pinch roller motor connected to an output end of the cylinder, and a pinch roller connected to an output end of the pinch roller motor, where the pinch roller motor is used to drive the pinch roller to rotate, and both the cylinder and the pinch roller motor are connected to the control unit in a communication manner. The cylinder is used for driving the pinch roller to be close to or far away from the driving groove 621 along the depth direction of the driving groove 621, and during feeding, the cylinder drives the pinch roller to be far away from the driving groove 621 along the depth direction of the driving groove 621 so as to facilitate feeding, when the braid to be tested is positioned at the driving groove 621, the cylinder drives the pinch roller to be close to the driving groove 621 along the depth direction of the driving groove 621, so that the pinch roller compresses the braid to be tested, and the pinch roller is driven to move in the conveying channel through rotation of the pinch roller. The cylinder drives the pinch roller to compress the braid to be tested, and then the pinch roller motor is controlled to start so as to convey the braid to be tested.
Further, the braid peeling force testing device 100 further includes a first sensor 622 for sensing whether the braid to be tested in the horizontal channel 62 moves to the driving slot 621, and the first sensor 622 is communicatively connected to the control unit. Thus, after the first sensor 622 senses that the braid to be tested moves to the driving groove 621 and is fed back to the control unit, the control unit controls the air cylinder to drive the pinch roller to be far away from the driving groove 621 along the depth direction of the driving groove 621, then controls the air cylinder to drive the pinch roller to be close to the driving groove 621 along the depth direction of the driving groove 621 so as to compress the braid to be tested, and finally controls the pinch roller motor to start so as to convey the braid to be tested. The automation of the braid peeling force test device 100 is improved.
Further, the horizontal channel 62 includes a feed inlet opposite to the discharge outlet, the feed inlet is provided with a guide plate 623, and the guide plate 623 extends obliquely in a direction away from the center line of the horizontal channel 62 along a direction away from the feed inlet. To guide the braid to be tested into the horizontal channel 62 and to improve the overall stability of the braid peeling force testing device 100.
Further, the braid peeling force testing device 100 further includes a second sensor 24 for sensing whether the braid to be tested reaches the press seat 21, and the second sensor 24 is communicatively connected to the control unit. After the second sensor 24 senses that the head end of the braid to be tested moves onto the pressing seat 21 and is fed back to the control unit, the control unit controls the pressing cylinder 22 to press down so as to clamp the head end of the braid.
Specifically, the second sensor 24 is mounted on the mounting surface and located on a side of the pressing seat 21 facing the discharge port. Of course, this is not a limitation.
It will be appreciated that, in order to facilitate the transport of the braid to be tested by the transport assembly 6, generally, the opposite ends of the braid to be tested are also connected, i.e. the head end and the tail end of the braid to be tested are sealed. In one embodiment, the braid to be tested includes a head end sealing section, a separation section, a connection section, a separation section, and a tail end sealing section in sequence from the head end toward the tail end of the braid to be tested. Thus, the head end closure segment needs to be removed prior to testing the peel force between the carrier tape and cover tape.
Further, the braid peeling force testing device 100 further includes a cutting assembly 7 disposed at the discharge port to cut the braid to be tested, and the cutting assembly 7 is in communication connection with the control unit. After the conveying component 6 conveys the braid to be tested to the position that the head end of the braid to be tested is positioned on the pressing seat 21 and the lower pressing cylinder 22 presses down to clamp the head end of the braid to be tested, the pressing wheel stops rotating to stop conveying the braid to be tested, and the cutting component 7 starts cutting off the braid to be tested so as to remove the head end sealing section of the braid to be tested, so that the follow-up peeling force between the carrier tape and the cover tape is tested. Thus, the braid to be tested is cut without manual intervention, and the automation of the braid peeling force testing device 100 is improved.
Specifically, as shown in fig. 4, the cutting assembly 7 includes two blades 71 located at two opposite sides of the discharge port, and a cutting driving member 72 for driving the two blades 71 to move relatively, where the cutting driving member 72 is communicatively connected to the control unit. The two blades 71 are driven to move relatively through the cutting driving piece 72, when the two blades 71 are close to each other, the braid to be tested can be cut off, and after the two blades 71 are far away from each other, a discharge hole can be opened for continuous conveying of the braid to be tested.
Further, the braid peeling force testing device 100 further comprises a storage box 8 arranged below the discharge hole. The cutting assembly 7 cuts off the head end of the braid to be tested, and after the pressing cylinder 22 is controlled to be lifted, the cut head end sealing section automatically falls into the storage box 8, so that automatic recovery of waste materials after cutting can be realized.
In the embodiment in which the preset direction is the vertical direction, the storage box 8 is disposed on the pressing seat 21 and is located below the pressing cylinder 22, and the opening of the storage box 8 is opposite to the pressing cylinder 22. Therefore, after the cutting assembly 7 cuts off the head end of the braid to be tested, and the pressing cylinder 22 is controlled to be lifted, the cut head end sealing section automatically falls into the storage box 8, and automatic recovery of the cut waste can be realized.
Further, referring to fig. 2, 3, and 5 to 6, the second clamping assembly 3 is located at a side of the conveying assembly 6 away from the mounting surface. The conveying channel is provided with a window 611 in a penetrating manner at a side far away from the seat body 1, the braid peeling force testing device 100 further comprises a cover tape extracting assembly 9 arranged between the window 611 and the second clamping assembly 3, and the cover tape extracting assembly 9 is used for extracting a cover tape from the window 611. Thus, after the braid to be tested is cut, the cover tape extracting assembly 9 extracts the cover tape through the window 611 and moves to the clamping jaw 33 of the second clamping assembly 3, and the clamping jaw 33 of the second clamping assembly 3 clamps the head end of the cover tape. To facilitate extraction of the cover tape.
Specifically, in the embodiment in which the preset direction is the vertical direction and the conveying channel includes the vertical channel 61, the second clamping assembly 3 is located on a side of the vertical channel 61 away from the mounting surface, and the window 611 is located on a side of the vertical channel 61 away from the mounting surface.
