When the hard supporting sheet and the soft material sheet are jacked together, the ejection module directly props against the hard supporting sheet, so that sharp tools such as tweezers assembled manually are prevented from touching the soft material sheet, damage to the soft material sheet is reduced, and the use effect of the soft material sheet is guaranteed.
The soft material sheets are automatically assembled in the device to be assembled by the taking and placing module, and the consistency of the attaching positions of the soft material sheets can be ensured.

Preferably, the soft material sheet 13 may be punched out of a soft material sheet having a large overall cross-sectional area. After bonding a single sheet of soft material to the single double sided adhesive, blanking is performed to form a plurality of sheets of soft material 13 that conform to the shape of the through hole 100. The double-sided tape 12 is adhered to the bottom of each of the soft material sheets 13. The cross-sectional area of the sheet of flexible material 13 is greater than the cross-sectional area of the through-hole 100.
The invention provides an assembling method which can automatically assemble the soft material sheets 13 in the material assembly provided by the invention into corresponding devices to be assembled.
Referring to fig. 1, 3, 5, the assembly method includes:
an automatic assembly device is provided. The automatic assembly device comprises a supporting platform 16, an ejection module 17 positioned below the supporting platform 16, a pressing module 15 positioned above the supporting platform 16 and a picking and placing module 14. For example, the support platform 16 may be horizontally disposed, and the support platform 16, the ejector module 17, the pressing module 15, and the pick-and-place module 14 may be assembled together by a fixing bracket or the like. The gravitational direction is defined as down and the antigravity direction is defined as up.
The material assembly is provided. The material assembly is placed on the support platform 16. The carrier film 10 is supported on the support platform 176, and the soft material sheet 13 is located above the carrier film 10.
After placing the material package on the support platform 16, the compacting module 15 is located above the material package. The pressing module 15 moves down and presses the base film 10. For example, the number of the pressing modules 15 may be plural, and the plural pressing modules 15 may surround the circumference of the soft material sheet 13 when the pressing modules 15 press the base film 10.
After the pressing module 15 presses the carrier film 10, the carrier film 10 is fixed. The ejection module 17 is located below the material assembly. The ejector module 17 moves upward and ejects the hard support sheet 11 together with the soft material sheet 13 to which the double-sided tape 12 is bonded. The sheet of flexible material 13 and the double-sided tape 12 are peeled off from the carrier film 10.
After the soft material sheet 13 is lifted up by the ejection module 17, the picking and placing module 14 grabs the soft material sheet 13, and assembles the soft material sheet 13 into the to-be-assembled device.
The soft material 13 is soft and is easily damaged. The hard support sheet 11 is made of a hard material, and can enhance the hardness of the bottom of the soft material sheet 13. During the process of upward moving and ejection of the ejection module 17, the ejection module 17 is directly contacted and abutted against the hard support sheet 11, and cannot be directly contacted with the soft material sheet 13 to damage the soft material sheet.
The hard supporting sheet 11 is of a sheet-like structure with a small thickness, and the attaching and assembling of the soft material sheet 13 in the member to be mounted is not affected. The hard support sheet 11 has good rigidity and strength, and can support the soft material sheet 13.
After the material assembly is placed on the support platform 16, the bottom film 10 should be prevented from sliding on the support platform 16, so as to prevent the ejection module 17 from being unable to accurately jack up the hard support sheet 11. Preferably, a positioning structure for positioning the base film 10 may be provided on the support platform 16. The specific structure of the positioning structure can be various.
In one example, referring to fig. 3, the support platform 16 and the base film 10 are provided with matching positioning posts 161 and positioning holes 101, respectively. For example, the support platform 16 may be provided with positioning posts 161, and the carrier film 10 may be provided with positioning holes 101 matching and corresponding to the positioning posts 161. When the carrier film 10 is placed on the support platform 16, the positioning posts 161 penetrate into the positioning holes 101 to position the carrier film 10 on the support platform 16, thereby preventing the carrier film 10 from sliding.
In one example, a positioning slot may be provided in the support platform 16. The base film 10 is positioned in the positioning groove of the support platform 16, so that the base film 10 can be prevented from sliding.
The specific structure of the pick-and-place module 14 can be varied. In one example, the pick-and-place module 14 includes a robot and a suction nozzle. For example, the robot may be a six-axis robot. After the sheet of soft material 13 is lifted, the suction nozzle sucks the sheet of soft material 13. The manipulator moves the suction nozzle and assembles the sheet of soft material 13 into the piece to be mounted. For example, the device to be assembled may be positioned in a determined position to facilitate assembly of the sheet of soft material 13.
The structure of the pressing module 15 may be various. In one example, the pressing module 15 includes a pressing member and a first cylinder for driving the pressing member to reciprocate. The first cylinder drives the pressing member to move toward the supporting platform 16 and press the base film 10. For example, the compacting member may include a compact. It will be appreciated that the first cylinder may be replaced with other transmission components such as hydraulic, electric, etc.
The structure of the ejection module 17 may be various. In one example, the ejection module 17 includes an ejection member and a second cylinder for driving the ejection member to reciprocate. The second cylinder drives the ejector to move towards the direction of the supporting platform 16, penetrates the through hole 100 and ejects the hard supporting sheet 11 and the soft material sheet 13 adhered with the double faced adhesive tape 12 together. For example, the ejector may be a ejector block or a round pin, or the like. It is understood that the second cylinder may be replaced with other transmission components such as hydraulic transmission, electric transmission, etc.
In this embodiment, referring to fig. 3, the support platform 16 is provided with a relief hole 160. The relief holes 160 correspond to the positions of the ejector. The relief holes 160 correspond to the positions of the through holes 100. When the second cylinder drives the ejector to move towards the direction of the supporting platform 16, the ejector penetrates out of the avoidance hole 160 and penetrates into the through hole 100, and the hard supporting sheet 11 and the soft material sheet 13 adhered with the double-sided tape 12 are lifted up together.
The soft material sheet 13 is soft and easy to damage. The assembling method provided by the invention can automatically assemble the soft material sheets 13 on corresponding products. The sheet 13 of soft material is not easily damaged during assembly.
In one example, the sheet of soft material 13 is sound absorbing cotton. The device to be assembled is a sound generating device module. The sound generating device module comprises a module shell and a sound generating device, and the sound generating device divides the inner space of the module shell into a front cavity and a rear cavity. After grabbing the lifted sound absorbing cotton, the picking and placing module 14 attaches the sound absorbing cotton to the inner wall of the front cavity or the rear cavity of the sound generating device module.
It will be appreciated that when a plurality of through holes 100 are provided in a matrix arrangement on the base film 10, each of the sheets of flexible material 13 corresponds to one of the through holes 100. Correspondingly, each soft material sheet 13 corresponds to one ejection module 17. Each of the ejection modules 17 corresponds to one of the pick-and-place modules 14.
The invention also provides a sound generating device module. The sound generating device module comprises a module shell and a sound generating device. The sound generating device divides the inner space of the module shell into a front cavity and a rear cavity. A sound absorbing member 20 is attached to the front or rear chamber. As shown in fig. 1 and 2, the sound absorbing member 20 is a combination of a soft material sheet 13, a double sided tape 12 and a hard support sheet 11 in the material assembly provided by the invention. The soft material sheet 13 is sound-absorbing cotton. The sound absorbing member 20 is attached to the inner wall of the front or rear chamber by a portion of double sided tape 12 around the hard support sheet 11.
In the present invention, the cross-sectional area of the sheet of soft material 13 is larger than the cross-sectional area of the through hole 100. The sheet 13 of flexible material is attached to one side surface of the base film 10 by a double-sided tape 12 and covers the through hole 100. The hard support sheet 11 is positioned in the through hole 100 and is adhered to the double-sided tape 12. The hard support sheet 11 is adhered to the bottom of the soft material sheet 13, and plays a supporting role, so that the soft material sheet 13 can be conveniently assembled in a piece to be assembled by using a machine.
After placing the material assembly on the support platform 16, the compacting module 15 compacts the carrier film 10. The ejector module 17 moves upward and ejects the hard support sheet 11 together with the soft material sheet 13 to which the double-sided tape 12 is adhered, and the soft material sheet 13 is peeled from the base film 10. The pick-and-place module 14 picks up the lifted sheet of soft material 13 and assembles the sheet of soft material 13 into the piece to be assembled.
The assembling method can automatically assemble the soft material sheets 13 in the corresponding devices to be assembled, improves the operation efficiency and reduces the labor cost.
The hard support sheet 11 is located at the bottom of the sheet of soft material 13. When the ejection module 17 ejects the hard support sheet 11 and the soft material sheet 13 together, the ejection module 17 directly abuts against the hard support sheet 11, so that sharp tools such as tweezers assembled manually are prevented from touching the soft material sheet 13, and damage to the soft material sheet 13 is reduced.
The picking and placing module 14 assembles the soft material sheet 13 in the piece to be assembled, so that consistency of attaching positions of the soft material sheet 13 can be ensured.
