Description

Technical Field

[0001] This invention relates to the field of electronic device assembly technology, and in particular to a pen-collecting device. Background Technology

[0002] When assembling components in existing electronic devices, double-sided tape is generally used for connection. For example, the shell and touch module inside a speaker are first attached to the touch module with double-sided tape, and then the shell is attached to the double-sided tape to connect them, thus assembling the shell and the touch module.

[0003] In the process of setting up double-sided tape, the existing method is to first use a suction pen device to absorb the double-sided tape, and then use a pressure holding device to maintain pressure on the double-sided tape after it has been absorbed and pasted. Therefore, two devices are required to perform the operation during the assembly process, which makes the operation cumbersome and affects the work efficiency of the assembly workshop. Summary of the Invention

[0004] The main objective of this invention is to provide a pen-absorbing device that can absorb double-sided tape through the adsorption holes of the pressure-holding head and maintain pressure on the double-sided tape through the pressure-holding head. This solves the technical problem that existing devices require separate adsorption and pressure-holding devices for adsorption and pressure maintenance, which leads to cumbersome operations for workers.

[0005] To achieve the above objectives, the present invention proposes a pen-absorbing device, which includes a driving body and a pressure-holding head. The pressure-holding head is located at one end of the driving body, and the side of the pressure-holding head away from the driving body has a pressure-holding surface for holding double-sided adhesive. The driving body drives the pressure-holding surface to hold the double-sided adhesive.

One end of the driving rod is slidably inserted through the gripping part, and the end of the driving rod away from the gripping part is connected to the pressure-holding head. The gripping part drives the driving rod to move so that the driving rod drives the pressure-holding surface to hold the double-sided adhesive.

[0007] Optionally, the driving body further includes a first limiting block and a first spring respectively disposed inside the gripping part. One end of the first spring abuts against the gripping part, and the other end of the first spring abuts against the first limiting block. The first limiting block is fixedly connected to the driving rod. The gripping part drives the first spring to press down, and the first spring drives the driving rod to move toward the double-sided adhesive through the first limiting block, so that the driving rod drives the pressure-holding surface to hold the double-sided adhesive.

The other second connector is located at the end of the drive body where the pressure holding head is located and is internally connected to the interior of the first connector, so that the first vacuum chamber and the second vacuum chamber are connected.

[0013] Optionally, the pen suction device further includes a positioning component, which is disposed on the pressure-holding surface of the pressure-holding head and connected to one end of the driving body. The double-sided adhesive has a positioning hole, wherein the positioning component can extend toward the double-sided adhesive and is used to pass through the positioning hole of the double-sided adhesive.

[0014] Optionally, the positioning component includes a pressing plate assembly and a first positioning member. The pressing plate assembly is connected to one end of the driving body and disposed on the pressure holding head. The first positioning member protrudes from the side of the pressing plate assembly away from the driving body and passes through the pressure holding surface. The pressing plate assembly drives the first positioning member to extend towards the double-sided adhesive and to pass through the positioning hole of the double-sided adhesive.

[0015] Optionally, the pressing plate assembly includes a self-locking structure and a pressing plate. The pressing plate is disposed within the pressure holding head. The first positioning member protrudes from the pressing plate. The self-locking structure includes a self-locking seat and a locking member. The self-locking seat is connected to one end of the driving body and installed on the pressure holding head. The locking member is disposed within the self-locking seat. The locking member includes a first locking member with a first inclined tooth and a second locking member with a second inclined tooth. The end of the second locking member opposite to the second inclined tooth abuts against the pressing plate.

[0016] Optionally, the self-locking seat is provided with a guide post, and the pressing plate is provided with a guide groove. The guide post is fitted through the guide groove so that the pressing plate is guided and connected to the self-locking seat.

[0017] Optionally, the first positioning member is provided in multiple sets, and the multiple sets of the first positioning member are arranged at intervals along the circumference of the pressing plate assembly;

[0018] And / or, the positioning component further includes a second positioning member, which is spaced apart from the first positioning member and protrudes from the pressure-holding surface. The second positioning member is used to pass through the positioning hole of the double-sided adhesive.

[0037] The present invention proposes a pen suction device 100.

[0038] In this embodiment of the invention, combined with Figures 1 to 2 As shown, the pen-absorbing device 100 includes a driving body 10 and a pressure-holding head 30. The pressure-holding head 30 is located at one end of the driving body 10. The side of the pressure-holding head 30 away from the driving body 10 has a pressure-holding surface 30a for holding double-sided adhesive. The driving body 10 drives the pressure-holding surface 30a to hold the double-sided adhesive. The pressure-holding surface 30a has an adsorption hole 30b. A first vacuum cavity is formed inside the pressure-holding head 30, communicating with the adsorption hole 30b, so that the adsorption hole 30b can be used to adsorb the double-sided adhesive. This can be combined with... Figure 6 and Figure 7 To understand, Figure 7 This is the pressure-holding state of the pen suction device. Figure 6 This indicates that the pressure holding state of the pen suction device has been cancelled.

[0039] In this embodiment, it can be understood that the driving body 10 can drive the pressure-holding head 30 in an automatic or manual manner, thereby pressing down on the pressure-holding head 30. This means the pressure-holding surface 30a can apply pressure to the double-sided adhesive, achieving pressure holding. In automatic drive mode, a cylinder or other driving component can be used. Regarding the adsorption holes 30b, when an external vacuum device evacuates the pressure-holding head 30, the internal cavity of the pressure-holding head 30 forms a first vacuum chamber. At this time, the adsorption holes 30b can adsorb the centrifuged paper of the double-sided adhesive. Specifically, the number of adsorption holes 30b can be one or more sets. Multiple sets of adsorption holes 30b can be arranged at intervals along the circumference of the pressure-holding surface 30a, for example, two, three, or four sets. The selection can be based on the actual amount of double-sided adhesive to be adsorbed, ensuring that one set of adsorption holes 30b corresponds to one double-sided adhesive.

[0040] The technical solution of this application includes a pressure-holding head 30, which forms a first vacuum chamber. The adsorption hole 30b, connected to this first vacuum chamber, can adsorb double-sided adhesive. After the double-sided adhesive is attached to the touch module, the driving body 10 drives the pressure-holding head 30 to maintain pressure on the adhesive, ensuring the connection strength between the adhesive and the touch module. Thus, during assembly work, the pen-absorbing device 100 of this application can achieve both adsorption and pressure holding. Compared to existing assembly methods that use separate adsorption and pressure holding devices, this application eliminates the need for workers to switch between adsorption and pressure holding devices, reducing cumbersome assembly procedures and improving worker efficiency.

[0041] In some exemplary embodiments, the working process of the pen-absorbing device 100 of this application is as follows: Both adhesive sides of the double-sided tape have centrifugal paper. The pressure-holding head 30 of the pen-absorbing device 100 first absorbs the adhesive side of the double-sided tape with the centrifugal paper. After absorption, the double-sided tape will be fixedly absorbed on the pressure-holding head 30. At this time, the centrifugal paper on the other adhesive side is manually peeled off, that is, the centrifugal paper on the adhesive side of the double-sided tape used to stick the touch module is peeled off. After peeling, the double-sided tape is pasted to the touch module through the pressure-holding head 30, and the pressure-holding head 30 holds the double-sided tape under pressure. After the pressure holding is completed, the pressure-holding head 30 releases the double-sided tape to release it, thus realizing the complete absorption and pressure holding process. After the process is completed, the remaining centrifugal paper on the adhesive side is peeled off manually in the subsequent process to completely remove the centrifugal paper on both adhesive sides of the double-sided tape. Then, the outer shell is assembled with the touch module through the double-sided tape.

[0042] The suction pen device of this application adds a suction function by setting suction holes. After the double-sided tape is suctioned, the double-sided tape is then pressurized by a pressure-holding head. The suction function does not affect the pressure-holding effect. This avoids cumbersome operation for workers and improves the work efficiency of the assembly workshop.

[0043] In one embodiment of the present invention, combined with Figures 1 to 2 As shown, the driving body 10 includes a gripping part 11 and a driving rod 13. One end of the driving rod 13 is slidably inserted through the gripping part 11, and the end of the driving rod 13 away from the gripping part 11 is connected to the pressure holding head 30. The gripping part 11 drives the driving rod 13 to move so that the driving rod 13 drives the pressure holding surface 30a to hold the double-sided adhesive.

[0044] In this embodiment, it can be understood that when the driving body 10 drives the pressure-holding head 30 manually, the operator can hold the grip part 11 with their hand and press down to provide a downward pressure to the grip part 11. At this time, the grip part 11 will also provide a downward pressure to the driving rod 13, so that the driving rod 13 can drive the pressure-holding head 30 to press down, so that the pressure-holding surface 30a applies pressure to the double-sided adhesive, thereby achieving pressure holding of the double-sided adhesive. The operation is convenient and easy for the operator to operate.

[0045] In one embodiment of the present invention, combined with Figure 3 and Figure 8 As shown, the driving body 10 also includes a first limiting block 15 and a first spring 17 respectively disposed inside the grip portion 11. One end of the first spring 17 abuts against the grip portion 11, and the other end of the first spring 17 abuts against the first limiting block 15. The first limiting block 15 is fixedly connected to the driving rod 13. The grip portion 11 drives the first spring 17 to press down, and the first spring 17 drives the driving rod 13 to move toward the double-sided adhesive through the first limiting block 15, so that the driving rod 13 drives the pressure-holding surface 30a to hold the double-sided adhesive.

[0046] In this embodiment, when the gripping part 11 is pressed down, it drives the first spring 17 to press down, thereby the first spring 17 can apply downward pressure to the first limiting block 15. Since the driving rod 13 has a sliding section and a threaded section connected together, the first limiting block 15 is threadedly connected to the threaded section, thus fixing the first limiting block 15 to the driving rod 13. As a result, the first limiting block 15 will drive the driving rod 13 downward, and the driving rod 13 will then apply downward pressure to the pressure holding head 30. In addition, the setting of the first spring 17 can also provide a reset effect for the gripping part 11. Specifically, by controlling the position of the first limiting block 15 on the driving rod 13, the range of elastic deformation of the first spring 17 can be controlled, thereby controlling the pressure applied to the pressure holding head 30 by the first spring 17.

[0047] In one embodiment of the present invention, combined with Figure 3 and Figure 8 As shown, the drive body 10 also includes a second limiting block 19, which is fixedly connected to the end of the drive rod 13 away from the gripping part 11.

[0048] In this embodiment, when the gripping part 11 moves downward, it is necessary to control the range of its movement. Therefore, the second limiting block 19 is also provided on the threaded section of the drive rod 13 to achieve a fixed connection between the two. At the same time, the second limiting block 19 abuts against the air guide block installed at one end of the self-locking seat 6131, thereby enabling the limit of the stroke of the gripping part 11.

[0049] In one embodiment of the present invention, combined with Figure 3 As shown, the gripping part 11 includes a first gripping member 111, a second gripping member 113, and a sliding member 115. The first gripping member 111 and the second gripping member 113 are connected through the sliding member 115, and one end of the drive rod 13 slides through the inner wall of the sliding member 115.

[0050] In this embodiment, it is understood that with the slider 115 provided, the connection between the first grip 111 and the second grip 113 can be realized, and the slider 115 is sleeved on the sliding section of the drive rod 13 to achieve a sliding connection with the sliding section of the drive rod 13. At the same time, one end of the first spring 17 abuts against the surface of the slider 115, so that when the first grip 111 and the second grip 113 are pressed down, the slider 115 will press down the first spring 17, giving the first spring 17 a downward force. The structure is simple and the pressing effect is good.

[0051] In one embodiment of the present invention, combined with Figure 2 As shown, the pressure-holding head 30 has a circular structure.

[0052] In this embodiment, the pressure holding head 30 is a circular structure, which allows the center of the pressure holding head 30 to be hollow, thereby providing clearance space. This clearance space allows the positioning component 60 to move, ensuring that the positioning component 60 has sufficient space to move.

[0053] In one embodiment of the present invention, combined with Figures 1 to 4 As shown, the pressure holding head 30 is provided with a first connector 40, the interior of which is connected to the first vacuum chamber.

[0054] In this embodiment, with the first connector 40 configured, one end of an external air pipe is connected to the first connector 40, and the other end of the air pipe is connected to an external vacuum pump. Thus, after the vacuum pump starts operating, a first vacuum chamber can be formed inside the pressure holding head 30, thereby enabling the adsorption hole 30b to adsorb the centrifugal paper of double-sided adhesive. The structure is simple and saves on the production cost of the device.

[0055] In one embodiment of the present invention, combined with Figures 1 to 4 As shown, a second vacuum chamber is formed inside the drive body 10. The drive body 10 is provided with at least two second connectors 50 that are respectively connected to the second vacuum chamber. One second connector 50 is located at the end of the drive body 10 away from the pressure holding head 30 and is located inside the drive body 10. The other second connector 50 is located at the end of the drive body 10 where the pressure holding head 30 is located and is internally connected to the interior of the first connector 40, so that the first vacuum chamber and the second vacuum chamber are connected.

[0056] In this embodiment, it is understood that the drive rod 13 can be hollow. Therefore, when one second connector 50 is located at the end of the drive body 10 away from the pressure-holding head 30 and inside the drive body 10, that is, the second connector 50 is installed on the end of the drive rod 13 away from the pressure-holding head 30 and communicates internally with the drive rod 13, the interior of the drive rod 13 will then communicate with the air guide block. Meanwhile, another second connector 50 is located at the end of the drive body 10 where the pressure-holding head 30 is located, that is, the other second connector 50 is located on the air guide block and communicates internally with the air guide block, thus achieving communication between the two second connectors 50. Furthermore, the second connector 50 located inside the drive body 10 will communicate with the external air pipe, achieving a complete pipeline connection process. The arrangement of the two second connectors 50 avoids direct connection of the air pipe to the first connector 40. Due to the final location of the air pipe, it will not interfere with the worker's work and allows for easy insertion and removal of the air pipe, facilitating the worker's work.

[0057] In one embodiment of the present invention, combined with Figure 1 and Figure 2 As shown, the pen suction device 100 also includes a positioning component 60, which is disposed on the pressure-holding surface 30a of the pressure-holding head 30 and connected to one end of the driving body 10. The double-sided tape has a positioning hole, wherein the positioning component 60 can extend toward the direction of the double-sided tape and is used to pass through the positioning hole of the double-sided tape.

[0058] In this embodiment, it is understood that the double-sided tape includes an adhesive layer and a centrifugal paper connected together, with positioning holes formed on the centrifugal paper. Therefore, to ensure the accuracy of the double-sided tape's position when adsorbed by the pressure head 30, a positioning component 60 is provided to cooperate with the positioning hole, achieving a positioning effect and thus ensuring accuracy when subsequently pasted onto the touch module. By providing the positioning component 60, this application enables the adsorption device to simultaneously perform positioning, adsorption, and pressure holding functions. Therefore, when workers perform these three steps, they do not need to switch tools back and forth, thereby reducing the tediousness of the work and improving the convenience of assembly workshop personnel.

[0059] In one embodiment of the present invention, combined with Figure 3As shown, the positioning component 60 includes a pressing plate assembly 61 and a first positioning member 63. The pressing plate assembly 61 is connected to one end of the driving body 10 and is disposed on the pressure holding head 30. The first positioning member 63 protrudes from the side of the pressing plate assembly 61 away from the driving body 10 and passes through the pressure holding surface 30a. The pressing plate assembly 61 drives the first positioning member 63 to extend toward the direction close to the double-sided adhesive for passing through the positioning hole of the double-sided adhesive.

[0060] In this embodiment, since the surface of the touch module is not touchable, and given the limited space, the extended state of the first positioning member 63 could affect the touch module. Therefore, a pressing plate assembly 61 is provided. The pressing plate assembly 61 can drive the first positioning member 63 to extend and retract; it extends when positioning is needed and retracts when attracted, avoiding any impact on the touch module. It should be noted that the first positioning member 63 can be a positioning pin or a positioning post; the type of the first positioning member 63 is not specifically limited here, and can be selected according to the design of the positioning hole. This can be combined with... Figure 4 and Figure 5 To understand, Figure 4 This refers to the extended state of the positioning component. Figure 5 This indicates the retracted state of the positioning component.

[0061] In one embodiment of the present invention, combined with Figure 3 and Figure 9 As shown, the pressing plate assembly 61 includes a self-locking structure 613 and a pressing plate 611. The pressing plate 611 is disposed within the pressure holding head 30. A first positioning member 63 protrudes from the pressing plate 611. The self-locking structure 613 includes a self-locking seat 6131 and a locking member 6133. The self-locking seat 6131 is connected to one end of the driving body 10 and installed on the pressure holding head 30. The locking member 6133 is disposed within the self-locking seat 6131. ​​The locking member 6133 includes a first locking member 6135 with a first inclined tooth 6135a and a second locking member 6137 with a second inclined tooth 6137a. One end of the first locking member 6135 away from the second inclined tooth 6137a abuts against the pressing plate 611. The end of the first locking member 6135 away from the first inclined tooth 6135a is provided with a second spring 17. The surface of the pressing plate 611 away from the second locking member 6137 is provided with a third spring 17. The self-locking structure 613 has a locked state. In the locked state, the pressing plate 611 drives the third spring 17, and the first inclined tooth 6135a disengages from the second inclined tooth 6137a. The second spring 17 drives the first inclined tooth 6135a so that the tip of the first inclined tooth 6135a abuts against the tip of the second inclined tooth 6137a.

[0062] In this embodiment, it can be understood that when the first positioning member 63 extends out of the pressure-holding surface 30a, it is in a self-locking state. Thus, the operator does not need to keep pressing the pressing plate 611 to keep the first positioning member 63 in the extended state. Of course, the self-locking structure 613 also has an unlocking state. In the unlocking state, the first inclined tooth 6135a and the second inclined tooth 6137a will mesh and connect to make the first locking member 6135 rotate, thereby driving the pressing plate 611 to move.

[0063] Specifically, a return spring 17 is provided inside the pressing plate 611 and the pressure holding head 30, and the return spring 17 is sleeved on the first positioning member 63. When the operator presses the pressing plate 611 down, the return spring 17 will provide an upward return force for the pressing plate 611, which is convenient for the operator to operate.

[0064] In one embodiment of the present invention, combined with Figure 4 As shown, the self-locking seat 6131 is provided with a guide post 6131b and the pressing plate 611 is provided with a guide groove. The guide post 6131b is fitted through the guide groove so that the pressing plate 611 is guided and connected to the self-locking seat 6131.

[0065] In this embodiment, when the pressing plate 611 is pressed, in order to ensure the accuracy of extending the first positioning member 63, a guide post 6131b and a guide groove are provided, so that the pressing plate 611 can improve the accuracy of movement during the pressing process.

[0066] Specifically, there can be two guide posts 6131b and two guide grooves, with one guide post 6131b corresponding to one guide groove. The two guide posts 6131b are set on opposite sides of the pressing plate 611, thereby further improving the accuracy of the movement of the pressing plate 611. Of course, the number of guide posts 6131b and guide grooves can also be three, four or five, etc. There is no specific limitation here. The number of both can be selected according to the actual required guiding effect and installation space.

[0067] In one embodiment of the present invention, combined with Figure 2 As shown, the first positioning member 63 is provided in multiple sets, and the multiple sets of first positioning members 63 are arranged at intervals along the circumference of the pressing plate assembly 61.

[0068] In this embodiment, a set of first positioning elements 63 may include at least two first positioning elements 63. The number of sets can be two, three, or four, and there is no specific limitation. The number of sets can be selected according to the number of double-sided adhesives to ensure that one double-sided adhesive corresponds to one set of first positioning elements 63. Therefore, with multiple sets of first positioning elements 63, the positioning and subsequent pasting of multiple double-sided adhesives can be realized simultaneously, improving the work efficiency of the assembly workshop.

[0069] In one embodiment of the present invention, combined with Figure 2 As shown, the positioning component 60 also includes a second positioning member 65, which is spaced apart from the first positioning member 63 and protrudes from the pressure-holding surface 30a. The second positioning member 65 is used to pass through the positioning hole of the double-sided adhesive.

[0070] In this embodiment, the second positioning member 65 enables the positioning of the positioning hole of the centrifugal paper of another double-sided adhesive, thereby ensuring the accuracy of the position of the double-sided adhesive when it is adsorbed by the pressure head 30. Therefore, the second positioning member 65 is provided to cooperate with the positioning hole to achieve the positioning effect, thereby ensuring the accuracy when it is subsequently pasted onto the touch module. It is understood that, due to the certain height difference between the structures of the touch module, there is a large space in some areas, so even if the second positioning member 65 does not retract, it will not cause damage to the touch module.

[0071] In one embodiment of the present invention, combined with Figure 2 As shown, the positioning component 60 also includes a third positioning member 67, which is spaced apart from the first positioning member 63 and protrudes from the pressure-holding surface 30a. The third positioning member 67 is used to pass through the positioning hole of the outer shell.

[0072] In this embodiment, since part of the touch module structure is a shell, and the shell is connected to the speaker shell, a third positioning member 67 is provided to ensure the stability of the pen suction device 100 when it sticks the double-sided tape to the touch module during the process of applying the double-sided tape. The positioning effect of the pen suction device 100 and the shell is achieved by the cooperation of the third positioning member 67 with the positioning hole of the shell, thereby ensuring the accuracy of the assembly.

[0073] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
