Description

Technical Field

[0001] This invention relates to the field of shell assembly equipment, and more particularly to a soft shell assembly device and its assembly mechanism. Background Technology

[0002] Some products on the market have detachable shells, which means that multiple outwardly tilted buckles are set on the edge of the upper shell. The upper and lower shells are assembled by snapping the buckles into the corresponding clips formed in the lower shell.

[0003] Currently, during the assembly of the upper and lower shells, the workers need to first place the upper shell on top of the lower shell, align each buckle with the outer edge of its corresponding window, and then use a pressing device to apply pressure to the upper shell so that the buckles slide from the edge of the window into the window, thus completing the assembly.

[0004] Some products have outer shells made of relatively soft materials, and the snaps on the upper shell are tilted outwards. When assembling the outer shell of such products using existing press-fitting equipment, the snaps, under the pressure exerted on the upper shell by the press-fitting equipment, move downwards and apply pressure to the side wall of the snap window. At this time, the movement of the snaps may be obstructed by the side wall of the snap window and bend, causing the snaps formed on the upper shell to not be able to be smoothly assembled into the corresponding snap windows formed on the lower shell. The posture of the snaps stuck in the snap windows needs to be adjusted manually afterward. Therefore, the existing press-fitting equipment has low assembly efficiency and low assembly quality, especially for shells where the snaps are arranged in a circumferential direction. Summary of the Invention

[0005] One advantage of this invention is that it provides a soft-shell assembly device and its assembly mechanism, which can adjust the buckle of the upper shell to a position corresponding to the corresponding snap window position, so as to prevent the buckle from bending due to obstruction by the side wall of the snap window during the assembly process, and ensure successful assembly of the upper shell and the lower shell.

[0006] To achieve at least one of the above advantages of the present invention, the present invention provides an assembly mechanism for assembling an upper housing and a lower housing, the upper housing being disposed above the lower housing and configured to deform under stress, the upper housing comprising a housing body and at least two sets of latches extending downward from the periphery of the housing body, wherein the at least two sets of latches are disposed opposite each other, each latch having a connecting portion and a head extending radially from the connecting portion, each head having an upward-facing abutting wall, the periphery of the lower housing forming a plurality of latching windows adapted to the size of the latches, the lower housing forming a latching step on the side wall of each latching window, characterized in that the assembly mechanism comprises:

The pressing surface of the pressing member, driven by the sliding member to move from the high end to the low end, is configured to apply pressure to the upper surface of the upper housing directly below. When at least two sets of side pressing members are driven to move downward to elastically deform by applying pressure to the connecting portions of at least two sets of latches, causing them to move closer to each other and the latches tend to reset, so that the heads of the latches remain in position corresponding to the latch window, the side pressing members are driven to move downward to push the heads into the latch window and move them below the latching step by abutting against the abutting wall. When the side pressing members are driven to pull out of the latch window, the latches can reset under their own elastic force and remain in the latch window by abutting against the latching step with the abutting wall of the head abutting against the latching step.

[0010] According to one embodiment of the present invention, the side pressure member has a drag-reducing wall, and the drag-reducing wall is formed on a side away from each other by two opposing sets of side pressure members. The angle between the direction in which the drag-reducing wall extends toward the bottom of the side pressure member and the direction in which the lower pressure member applies pressure to the upper housing is an acute angle.

[0033] The following description is intended to disclose the present invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the invention.

[0034] Those skilled in the art should understand that, in the disclosure of this invention, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limiting this invention.

[0035] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0036] refer to Figures 1 to 4 A preferred embodiment of the soft-shell assembly apparatus according to the present invention will be described in detail below. The soft-shell assembly apparatus includes an assembly mechanism 100. The assembly mechanism 100 is used to assemble an upper shell 80 and a lower shell 90, the upper shell 80 being disposed above the lower shell 90, and the upper shell 80 being configured to deform under force.

[0037] The upper housing 80 includes a housing body 81 and at least two sets of latches 82 extending downward from the periphery of the housing body 81, wherein the at least two sets of latches 82 are arranged opposite each other. Each latch 82 has a connecting portion 821 and a head 822 extending radially from the connecting portion 821, and each head 822 has an upward-facing abutting wall 8221. Under the absence of external force, the distance between the heads 822 of two opposing latches 82 is greater than the distance between the connecting portions 821 of the two latches 82. The periphery of the lower housing 90 forms a plurality of latch windows 9001 adapted to the size of the latches 82. The lower housing 90 forms a latching step 91 on the side wall of each latch window 9001. When the upper housing 80 is assembled to the lower housing 90, the abutting wall 8221 abuts against the latching step 91.

[0038] Specifically, the assembly mechanism 100 includes a mounting component 10, a moving component 20, and a pressing assembly 30.

[0039] refer to Figure 4 Specifically, the mounting member 10 has a high end portion 11 and a low end portion 12 below the high end portion 11. The pressing assembly 30 includes a lower pressing member 31 and at least two sets of side pressing members 32. The lower pressing member 31 is mounted on the conveyor member 20, and the lower pressing member 31 is slidably mounted on the mounting member 10 in a manner that allows it to be driven by the conveyor member 20 to move vertically back and forth between the high end portion 11 and the low end portion 12.

[0040] refer to Figure 8 The pressing member 31 has a pressing surface 3101. Driven by the moving member 20, the pressing surface 3101 of the pressing member 31, which moves from the high end portion 11 to the low end portion 12, can apply pressure to the upper surface of the upper housing 80 directly below, so as to move the upper housing 80 downward as a whole, thereby facilitating the successful assembly of the upper housing 80 and the lower housing 90.

[0041] The pressing member 31 extends downward along the periphery of the pressing surface 3101 to form the side pressing member 32, and at least two sets of the side pressing members 32 are arranged opposite to each other to form a pressure port 3201.

[0042] The pressure port 3201 formed by the side pressure member 32 can gradually retract part of the upper housing 80 during the downward movement of the mounting assembly 30 until the end of the side pressure member 32 away from the lower pressure member 31 abuts against the abutment wall 8221 formed by the buckle 82. During the retraction process, the inner wall of the pressure port 3201 applies pressure to the connecting part 821, causing the buckle 82 to undergo elastic deformation. The heads 822 of the two opposing buckles 82 approach each other and the buckles 82 tend to return to their original position, so that the position of the heads 822 corresponds to the position of the latch window 9001. Furthermore, during the downward movement of the upper housing 80 driven by the mounting assembly 30, the side pressure member 32 can apply downward pressure to the buckle 82 through the abutment wall 8221, so that the buckle 82 can be smoothly inserted into the latch window 9001 until the abutment wall 8221 abuts against the latching step 91.

[0043] During the process of the moving component 20 driving the mounting assembly 30 to move upward, the side pressure member 32 can be moved out of the card window 9001 independently because the buckle 82 is limited by the locking step 91. The buckle 82 is reset due to the loss of the squeezing effect of the side pressure member 32. Therefore, the abutment wall 8221 and the locking step 91 are completely abutted, thereby achieving a stable assembly.

[0044] Preferably, the mounting member 10 forms a first guide rail 13, which extends vertically, and the pressing member 31 is slidably mounted on the first guide rail 13.

[0045] refer to Figure 6 It is worth mentioning that the side pressure member 32 has a drag-reducing wall 321. The drag-reducing wall 321 is formed on the opposite side of the two sets of side pressure members 32. The angle between the direction in which the drag-reducing wall 321 extends toward the bottom of the side pressure member 32 and the direction in which the lower pressure member 31 applies pressure to the upper housing 80 is an acute angle. In other words, the portion of the side pressure member 32 that forms the drag-reducing wall 321 has a design that is wider at the top and narrower at the bottom. This allows the bottom of the drag-reducing wall 321 to easily enter the window 9001 through its opening as the side pressure member 32 moves downwards to move the latch 82 into the window 9001. Conversely, as the side pressure member 32 moves away from the window 9001, the contact area between the drag-reducing wall 321 and the inner wall of the window 9001 gradually decreases. Therefore, the resistance of the side wall of the window 9001 to the side pressure member 32 is small, reducing the assembly difficulty of the assembly mechanism 100 in assembling the upper housing 80 and the lower housing 90. Preferably, the mounting member 10 includes a plurality of side pressure members 32, which are spaced apart in a circumferential direction. In this way, for a housing in which the snap fastener is arranged in an annular direction, the drag-reducing wall 321 can be formed by the side pressure member 32 arranged in the annular direction, thereby enabling the assembly of the housing in which the snap fastener 82 is arranged in an annular direction, and the separation of the side pressure member 32 from the housing after assembly.

[0046] Preferably, the conveyor member 20 includes a first conveyor assembly 21. The pressing member 31 is movably connected to the first conveyor assembly 21 in a vertical reciprocating manner between the upper end portion 11 and the lower end portion 12. In one example, the first conveyor assembly 21 is implemented as including a cylinder.

[0047] refer to Figure 7In a preferred embodiment, the first moving assembly 21 includes a connecting rod 211, a balancing member 212, and a connecting member 213. The connecting rod 211 includes a first connecting portion 2111 and a second connecting portion 2112. The two ends of the first connecting portion 2111 are pivotally connected to the mounting member 10 and the second connecting portion 2112, respectively. The end of the second connecting portion 2112 away from the first connecting portion 2111 is pivotally connected to the pressing member 31. The balancing member 212 is vertically slidably connected to one end of the connecting member 213, and the end of the connecting member 213 away from the balancing member 212 is connected to the pressing member 31, so that when the pressing member 31 moves vertically from the high end portion 11 to the low end portion 12, the balancing member 212 moves from the low end portion 12 to the high end portion 11 via the connecting member 213, and vice versa.

[0048] The balancing member 212 provides a pulling force opposite to the direction of gravity to the pressing assembly 30 through the connecting member 213. The balancing member 212, through the connecting member 213, balances part of the gravity acting on the pressing assembly 30, thereby reducing the downward movement speed of the pressing member 31 and preventing excessive downward movement of the pressing member 31. Furthermore, the balancing member 212, through the connecting member 213, provides a pulling force for the reset of the pressing member 31, making it easier for operators to control.

[0049] In this way, when the first connecting part 2111 and the second connecting part 2112 are unfolded, the second connecting part 2112 drives the pressing assembly 30 to move downward so that the end of the side pressing member 32 away from the lower pressing member 31 abuts against the abutting wall 8221 formed by the corresponding buckle 82, thereby controlling the downward stroke of the side pressing member 32, preventing the upper housing 80 from being continuously stressed, and reducing the pressure loss rate of the upper housing 80. When the first connecting part 2111 and the second connecting part 2112 are retracted, the second connecting part 2112 drives the pressing assembly 30 to move upward to reset.

[0050] Preferably, the mounting member 10 further forms a displacement limiting structure 14, the displacement limiting structure 14 extending vertically, and the balancing member 212 is slidably mounted on the displacement limiting structure 14.

[0051] In one example, the displacement limiting structure 14 may be implemented as including a light rod.

[0052] Furthermore, the first moving assembly 21 also includes a control lever 214. The control lever 214 is mounted on the connecting rod 211 to provide an assembly operator with a position to adjust the connecting rod 211.

[0053] Preferably, the vertical distance between the end of the control lever 214 away from the connecting rod 211 and the connection point between the connecting rod 211 and the mounting member 10 is greater than the vertical distance between the connection point of the second connecting part 2112 and the pressing member 31 and the connection point between the connecting rod 211 and the mounting member 10. In this way, the power arm is always greater than the resistance arm, making it easier for the assembly personnel to operate.

[0054] Preferably, the first conveyor assembly 21 further includes at least one rotating wheel 215. The rotating wheel 215 is rotatably mounted on the high end portion 11, and the connector 213 is wound around the rotating wheel 215. Force is transmitted through the cooperative action of the rotating wheel 215 and the connector 213.

[0055] In one example, the connector 213 is implemented as including a chain, and the rotating wheel 215 is implemented as including a gear that meshes with the chain.

[0056] Furthermore, the conveyor member 20 also includes a second conveyor member 22. The second conveyor member 22 is mounted on the mounting member 10 and is used to push the pressing member 31 vertically downward.

[0057] Furthermore, the assembly mechanism 100 also includes a sensor 40. The second belt-moving member 22 is controllably connected to the controller 200. The sensor 40 is communicatively connected to the controller 200 to monitor whether the pressing member 31 drives the side pressing member 32 to move to abut against the abutting wall 8221 formed by the corresponding buckle 82.

[0058] In other words, the assembler holds the control lever 214 to push the connecting rod 211 out. The connecting rod 211 drives the lower pressure member 31 and the side pressure member 32 to move downwards until the end of the side pressure member 32 away from the lower pressure member 31 abuts against the abutting wall 8221 formed by the corresponding buckle 82. At this point, the controller 200 controls the second conveyor 22 to start according to the monitoring result of the sensor 40, so that the lower pressure surface 3101 presses against the upper housing 80, and the side pressure member 32 pushes the buckle 82 to insert into the snap window 9001, thereby realizing the assembly of the upper housing 80 and the lower housing 90. Compared with a single assembly, the upper housing 80 is subjected to pressure twice, and the first conveyor assembly 21 is equipped with the balance member 212, which avoids continuous pressure and reduces the pressure on the upper housing 80 during one of the assemblies, preventing the upper housing 80 and the lower housing 90 from breaking under stress.

[0059] In one example, the second belt conveyor 22 is implemented as including a cylinder.

[0060] refer to Figure 4 and Figure 5 Furthermore, the soft-shell assembly device also includes a support platform 300 and a worktable 400.

[0061] The workbench 400 has a support surface 40001. The mounting component 10 is mounted on the support surface 40001.

[0062] Specifically, the support platform 300 includes a base 310. The base 310 is mounted on the support surface 40001 formed by the workbench 400. The base 310 forms a support groove 31001 for holding the lower housing 90. The upper housing 80 is placed on the upper surface of the lower housing 90, and the buckle 82 corresponds to the position of the latch window 9001. The support platform 300 is located directly below the pressing surface 3101 so that the upper housing 80 and the lower housing 90 can be assembled by the assembly mechanism 100.

[0063] In one embodiment, the base 310 is slidably mounted on the support surface 40001 formed by the workbench 400, and the support platform 300 can be moved into or out directly below the pressing surface 3101.

[0064] Preferably, the worktable 400 forms a second guide rail 410, and the base 310 is slidably mounted on the second guide rail 410 to limit the movement of the base 310 along the extension direction of the second guide rail 410.

[0065] The worktable 400 forms an assembly position and an opposite loading / unloading position along the extension direction of the second guide rail 410. The support platform 300 is configured to move back and forth between the assembly position and the loading / unloading position. The assembly position is located directly below the lower pressure surface 3101. When the support platform 300 is in the assembly position, the assembly mechanism 100 can assemble the upper housing 80 and the lower housing 90; when the support platform 300 is in the loading / unloading position, the upper housing 80 and the lower housing 90 can be loaded / unloaded.

[0066] Preferably, the support platform 300 further includes a cover 320. The cover 320 forms a communicating channel 32001. The cover 320 is coverably installed on the base 310. When the cover 320 is closed on the base 310, the inner wall of the cover 320 forming the communicating channel 32001 can limit part of the side wall of the upper housing 80.

[0067] Preferably, the cover 320 is pivotally connected to the base 310.

[0068] refer to Figure 9 In a preferred embodiment, when the cover 320 is fitted onto the base 310, the cross-sectional diameter of the cover 320 gradually decreases vertically from top to bottom. Thus, after the lower housing 90 is placed in the support groove 31001 formed by the base 310, the cover 320 pivots to cover the base 310. The lower housing 90 is positioned above the base via the connecting channel 32001 along the side wall of the connecting channel 32001.

[0069] The present invention also provides a method for operating the soft-shell assembly device, comprising the following steps:

[0070] (A) The lower housing 90 is placed on the support platform 300, and the upper housing 80 is placed above the lower housing 90;

[0071] (B) The moving member 20 drives the side pressure member 32 and the lower pressure member 31 to move downwards to assemble the upper housing 80 and the lower housing 90.

[0072] (A1) The lower housing 90 is placed in the bearing groove 31001 formed by the base 310.

[0073] (A2) The cover 320 pivots to close with the base 310.

[0074] (A3) The upper housing 80 is placed above the lower housing 90 along the side wall of the connecting channel 32001.

[0075] (A4) The support platform 300 drives the upper housing 80 and the lower housing 90 to move together directly below the pressure surface 3101.

[0076] (B1) Push the connecting rod 211 to drive the lower pressure member 31 and the side pressure member 32 to move downward until the end of the side pressure member 32 away from the lower pressure member 31 abuts against the abutting wall 8221 formed by the corresponding buckle 82.

[0077] (B2) The controller 200 controls the second belt shifter 22 to start according to the monitoring result of the sensor 40 to push the lower pressure member 31 and the side pressure member 32 to continue to move downward, so that the lower pressure surface 3101 squeezes the upper housing 80, and the side pressure member 32 pushes the abutting wall 8221 of the buckle 82 to abut against the snap step 91.

[0078] (B3) The pressure assembly 30 is reset.

[0079] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the invention. The advantages of the present invention have been fully and effectively realized. The functional and structural principles of the present invention have been demonstrated and explained in the embodiments; any variations or modifications can be made to the implementation of the present invention without departing from these principles.
