Description

Technical Field

[0001] This utility model belongs to the field of assembly tooling technology, and specifically relates to a support material positioning mechanism and a support assembly mechanism. Background Technology

[0002] The relevant technology involves a bracket and a housing structure. The bracket and housing are positioned within the bottom frame, requiring the bracket to be first positioned within the housing structure, ensuring it is aligned with the L-shaped positioning hole without gaps. The bracket is then screwed onto the housing. Ensuring proper assembly in both directions simultaneously for a single workpiece is challenging. During the assembly and pressure holding process, even slight pressure deviations or insufficient height can cause the bracket to tilt or misalign, leading to poor assembly and severely impacting the accuracy of subsequent material assembly.

[0003] Therefore, in view of the above shortcomings, this utility model is proposed. Utility Model Content

Furthermore, the structure is simple to operate, requiring only one person, thus saving manpower and increasing production capacity. Attached Figure Description

[0059] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0060] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also include the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein are not construed as requiring them to be performed in a particular order described or illustrated unless the order of performance is explicitly indicated. It should also be understood that additional or alternative steps may be used.

[0061] Although terms such as first, second, third, etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Therefore, the first element, component, region, layer, or segment discussed below may be referred to as the second element, component, region, layer, or segment without departing from the teachings of the exemplary embodiments.

[0062] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "over," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure is flipped, an element described as "below other elements or features" or "below other elements or features" would subsequently be oriented as "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0063] The first aspect of this utility model provides a support material positioning mechanism 100, which can be used in a support positioning assembly mechanism 1 and is suitable for achieving precise positioning of the support and the shell.

[0064] Reference Figures 1-8 The support material positioning mechanism 100 provided in this embodiment of the utility model includes a base 10, a flip support frame 20, a positioning mechanism 40, and a pushing mechanism 30. The base 10 is provided with a clamping and fixing block 11. The flip support frame 20 has a first end and a second end. The first end is hinged to the base 10, and the second end can be fitted and locked with the clamping and fixing block 11 when the flip support frame 20 is flipped into position. The positioning mechanism 40 is slidably connected to the flip support frame 20 and can press the support when the flip support frame 20 is locked. It can also slide along a first direction in the pressed state. The pushing mechanism 30 is slidably connected to the flip support frame 20 and can slide between a first position and a second position along a second direction. The second direction is not parallel to the first direction. The pushing mechanism 30 is connected to the positioning mechanism 40 and can drive the positioning mechanism 40 to slide to push the support by sliding to the second position. When the pushing mechanism 30 slides to the second position, the positioning mechanism 40 pushes the support to the precise position.

[0065] The bracket positioning and assembly mechanism 1 provided in the second aspect of this utility model includes, in addition to the bracket material positioning mechanism 100 described above, a material positioning module 200 and a protective cover module 300. The material positioning module 200 is disposed on the base 10 and is used to place and position the housing. One end of the protective cover module 300 is hinged to the base 10, and the other end is detachably connected to the base 10. It is adapted to fix the housing by flipping over to cover it.

[0066] The material positioning module 200 is fixed to the base 10 and is used to position the bottom and outer periphery of the housing; one end of the protective cover module 300 is hinged to the base 10, and the other end is detachably connected to the base 10, and is used to position the upper part of the housing, while also defining and exposing the installation space of the bracket for bracket loading, positioning and locking operations.

[0067] The process of the bracket material positioning mechanism 100 is located after the housing positioning and bracket loading, and is mainly used to realize the positioning operation of the bracket.

[0068] Specifically, the flip support frame 20 is strip-shaped, with its first end hinged to the base 10 and capable of rotating around the first end. When it rotates to be parallel to the base 10, i.e., when flipped into position, it can be fitted and locked with the locking block 11. The positioning mechanism 40 is disposed on the flip support frame 20 and can rotate synchronously with the flip support frame 20. It can also press the bracket when the flip support frame 20 is flipped into position. At the same time, since the positioning mechanism 40 is slidably connected to the flip support frame 20, it can also slide on a plane parallel to the base 10. The pushing mechanism 30 is slidably connected to the flip support frame 20 and connected to the positioning mechanism 40. When the flip support frame 20 is flipped into position, the pushing mechanism 30 can slide from the first position to the second position and synchronously drive the positioning mechanism 40 to slide to push the bracket. When the pushing mechanism 30 moves to the second position, the bracket is pushed to the precise position to await the locking operation.

[0069] Furthermore, during the aforementioned process, since the first direction of the positioning mechanism 40 is not parallel to the second direction of the propulsion mechanism 30, i.e., the first direction and the second direction form an angle, the positioning mechanism 40 has displacement in two directions when it is pushed. This allows it to cooperate with the protective cover module 300 to achieve positioning of the bracket in two directions, i.e., to achieve precise positioning of the bracket.

[0070] Next, the bracket and the housing are screwed together. After connection, the locking of the flip support frame 20 and the protective cover module 300 is released, and the flip support frame 20 and the protective cover module 300 are rotated to remove the restriction on the housing and bracket. The assembled housing and bracket are then removed, completing the entire assembly process. The above cycle can then be repeated to achieve continuous assembly of the housing and bracket.

[0071] The bracket material positioning mechanism 100 provided in this embodiment of the utility model is achieved by setting a rotatable flip support frame 20, on which a sliding positioning mechanism 40 and a pushing mechanism 30 are set, and the positioning mechanism 40 and the pushing mechanism 30 are connected. In this way, by rotating the flip support frame 20, the positioning mechanism 40 can be pressed against the bracket, and by sliding the pushing mechanism 30, the positioning mechanism 40 can be driven to slide and push the bracket to a precise position. This achieves positioning of the bracket in two directions, that is, precise positioning of the bracket, thereby improving the assembly yield of the bracket and the shell. Moreover, the operation of the above structure is simple and can be operated by one person, thus saving manpower and increasing production capacity.

[0072] In one embodiment, the flip support frame 20 is provided with a slide rail along a first direction and a slider adapted thereto, the positioning mechanism 40 is mounted on the slider, the flip support frame 20 is also provided with a slide rail along a second direction, and the pushing mechanism 30 is adapted thereto to slide.

[0073] In one embodiment, a latching module 50 is further included. The latching module 50 includes a limiting part, a hook part 53, and a first spring 55. The limiting part includes a first limiting block 51 and a second limiting block 52 spaced apart along the length of the flip support frame 20. The first limiting block 51 and the second limiting block 52 are respectively disposed on both sides of the propulsion mechanism 30. The hook part 53 is hinged to the propulsion mechanism 30. The hook part 53 can hook and adapt to the first limiting block 51 to limit the propulsion mechanism 30 to a first position. The hook part 53 can abut against the first limiting block 51 to limit the propulsion mechanism 30 to a second position. The first spring 55 is connected between the second limiting block 52 and the propulsion mechanism 30 and is adapted to provide elastic force to the propulsion mechanism 30 to limit the propulsion mechanism 30 to the first position or the second position.

[0074] Specifically, the first limiting block 51 and the second limiting block 52 are respectively disposed on both sides of the propulsion mechanism 30, so that the propulsion mechanism 30 can move between the first limiting block 51 and the second limiting block 52. The first spring 55 is connected between the propulsion mechanism 30 and the second limiting block 52 and is adapted to adjust the elastic force between the two.

[0075] The hook part 53 is hinged to the side of the propulsion mechanism 30, and preferably the hinge axis is perpendicular to the sliding direction of the propulsion mechanism 30. This allows it to rotate relative to the propulsion mechanism 30 to adjust its position. Furthermore, the connection relationship with the first limiting block 51 can be adjusted by rotation, achieving hook engagement or abutment engagement with the first limiting block 51. The engagement positions of the hook part 53 and the first limiting block 51 differ between hook engagement and abutment engagement. Preferably, in hook engagement, the hook part 53 is connected to the side of the first limiting block 51 away from the propulsion mechanism 30; in abutment engagement, the hook part 53 abuts against the side of the first limiting block 51 close to the propulsion mechanism 30. That is, the position of the hook part 53 relative to the flipping support frame 20 and the position of the propulsion mechanism 30 connected to the hook part 53 are different in the two engagement states. In hook engagement, the propulsion mechanism 30 is in the first position; in abutment engagement, the propulsion mechanism 30 is in the second position. By operating the hook part 53, the propulsion mechanism 30 can be switched between the first and second positions.

[0076] In the first position, the hook 53 is hooked and fitted with the first limiting block 51, the first spring 55 is in a stretched state, and the propulsion mechanism 30 is stabilized in the first position under the action of two opposite forces, both of which are away from the propulsion mechanism 30. In the second position, the hook 53 is abutted and fitted with the first limiting block 51, the second spring 54 is in a compressed state, and the propulsion mechanism 30 is stabilized in the first position under the action of two opposite forces, both of which are towards the propulsion mechanism 30.

[0077] Of course, in other embodiments, the limiting part may only include the first limiting block 51. In this case, the first spring 55 is disposed between the propulsion mechanism 30 and the first limiting block 51, and is in a compressed state when the hook part 53 is hooked and adapted to the first limiting block 51, and in a stretched state when the hook part 53 is in abutting state with the first limiting block 51. It can cooperate with the hook part 53 to realize the switching of the first position and the second position of the propulsion mechanism 30.

[0078] By setting the above structure, this embodiment can realize the controllable switching between the first position and the second position of the propulsion mechanism 30, thereby enabling precise control of the positioning mechanism 40, thus avoiding interference between the positioning mechanism 40 and the bracket to prevent the flipping support frame 20 from flipping, and also using the positioning mechanism 40 to stabilize the bracket in a precise position for subsequent operations.

[0079] In one embodiment, the hook portion 53 has a first end and a second end, the first end forming a hook; the latching module 50 further includes a second spring 54, the second spring 54 being connected between the push mechanism 30 and the second end of the hook portion 53, and is adapted to drive the hook portion 53 to rotate to be adapted to connect with the first limiting block 51.

[0080] Specifically, the hook portion 53 is located on the side of the propulsion mechanism 30 opposite to the protective cover module 300, which facilitates operation by staff. Simultaneously, the side of the propulsion mechanism 30 opposite to the protective cover module 300 forms a concave arc-shaped surface, providing rotational space for the second end of the hook portion 53. The second spring 54 is located on the same side of the propulsion mechanism 30 as the hook portion 53, specifically at the arc-shaped surface. It is in a compressed state, with one end connected to the propulsion mechanism 30 and the other end connected to the second end of the hook portion 53. Thus, the second spring 54 provides a stable rotational drive for the second end of the hook portion 53, enabling the first end of the hook portion 53 to stably hook or abut against the first limiting block 51.

[0081] This embodiment improves the reliability of the hook part 53 through the above-described structural design, thereby improving the reliability of the propulsion mechanism 30 and preventing the propulsion mechanism 30 from moving when not in operation.

[0082] In one embodiment, the side of the propulsion mechanism 30 away from the protective cover module 300 is also provided with a protruding gripping part 32. The gripping part 32 is located on the other side of the arc surface opposite to the first limiting block 51 and is used by the staff to grip and slide the propulsion mechanism 30.

[0083] In one embodiment, a foolproof mechanism 60 is also included. The foolproof mechanism 60 includes a foolproof base 61 and an interference module 62. The foolproof base 61 includes an L-shaped connecting plate and a limiting plate. The connecting plate is fixed to the base 10, and the limiting plate is vertically arranged. The interference module 62 is connected to the limiting plate by a third spring 63 parallel to the second direction. The interference module 62 can interfere with the propulsion mechanism 30 in the second position to prevent the flip support frame 20 from flipping, while having no interference with the propulsion mechanism 30 in the first position.

[0084] Specifically, both the anti-fool base 61 and the interference module 62 are configured corresponding to the gripping part 32. That is, when the propulsion mechanism 30 is not in the first position, the gripping part 32 interferes with the flipping support frame 20 when it flips, preventing the flipping support frame 20 from continuing to rotate. When the propulsion mechanism 30 is in the first position, the gripping part 32 allows the flipping support frame 20 to flip normally due to the distance between it and the interference module 62. After the flipping support frame 20 is flipped into position, when the propulsion mechanism 30 is slid to the second position, the interference module 62, due to the third spring 63, can slide synchronously with the propulsion mechanism 30 after contacting it, thereby avoiding interference with the normal operation of the propulsion mechanism 30.

[0085] This embodiment further enhances the positional constraint of the propulsion mechanism 30 by incorporating a foolproof mechanism 60, ensuring that it is in the first position before the flip support frame 20 flips into place. This, in turn, guarantees the position of the positioning mechanism 40 and prevents interference damage to the support frame caused by the positioning mechanism 40 being in an incorrect position during the flipping process of the flip support frame 20. Furthermore, the inclusion of a third spring 63 prevents interference with the normal operation of the propulsion mechanism 30.

[0086] In one embodiment, the locking block 11 is provided with a locking groove; the end of the flip support frame 20 is provided with a locking mechanism 70, which includes a buckle 72, a buckle 72 fixing block 71, a buckle 72 and a fourth spring 73, wherein the buckle 72 fixing block 71 is fixed to the end of the flip support frame 20 and forms a connecting ear; the middle part of the buckle 72 is hinged to the connecting ear, and the lower end of the buckle 72 is provided with a latch, which can rotate when the flip support frame 20 is flipped into place to fit and engage with the locking groove; the fourth spring 73 is disposed between the buckle 72 fixing block 71 and the buckle 72, and is used to drive the upper end of the buckle 72 to flip and lock the latch in the locking groove.

[0087] Specifically, the latch 72 and the latch fixing block 71 are sleeve-shaped structures with the same cross-sectional shape as the flip support frame 20. The latch 72 is fitted onto the second end of the flip support frame 20 and is fixedly connected to it. A notch is formed on the upper side of the latch fixing part, and the two side walls at the notch position form connecting ears with through holes. The middle part of the latch 72 is hinged to the connecting ears via a pin passing through the through hole, allowing it to rotate relative to the pin. A latch tongue is formed at the lower end of the latch 72, which can rotate to engage with the locking groove when the flip support frame 20 is flipped into position. A fourth spring 73 is disposed between the latch 72 and the latch fixing block 71, and gives the latch 72 a tendency to continue rotating towards the locking groove, thus confining the latch 72 within the locking groove.

[0088] This embodiment achieves the limitation of the flip support frame 20 to the flip position through the above structure, which can improve the stability of subsequent operations.

[0089] In one embodiment, the buckle 72 is further connected to a T-shaped abutment portion in the middle. The fourth spring 73 is a compression spring and is disposed at the notch. One end of the spring 73 is connected to the buckle 72 fixing block 71, and the other end is connected to the abutment portion. In this way, the fourth spring 73 can provide rotation drive for the buckle 72 through the abutment portion to limit the buckle 72 in the locking groove.

[0090] Of course, in other embodiments, the latch 72 may also be formed as a flat plate structure, and the fourth spring 73 may be formed as a tension spring and connected to the other end of the latch 72 relative to the latch tongue to provide rotational drive for the latch 72 to confine the latch 72 in the locking groove.

[0091] In one embodiment, the positioning mechanism 40 includes a contour positioning block 41, a silicone pressure head 42, a first positioning block 43, and a second positioning block 44. The contour positioning block 41 is slidably mounted on the flip support frame 20. One end of the contour positioning block 41 is provided with a drive rail 45 forming an angle with the second direction, and the other end of the contour positioning block 41 is also provided with a groove. The silicone pressure head 42 protrudes from the bottom surface of the contour positioning block 41 and is adapted to press the support. The first positioning block 43 is disposed in the groove and is adapted to cooperate with the side of the support to push the support to a precise position. The second positioning block 44 is connected to both sides of the contour positioning block 41 and is adapted to be fitted and pressed with both ends of the support. The second positioning block 44 is provided with a positioning hole adapted to be fitted with the screw hole in the support. The pushing mechanism 30 is provided with a drive wheel 31, which is disposed in the drive rail 45. The pushing mechanism 30 is adapted to drive the contour positioning block 41 to slide through the drive wheel 31.

[0092] The contour positioning block 41 is formed as a flat plate structure, which is slidably mounted on the flip support frame 20 in a manner parallel to the plane of the flip support frame 20, and can slide parallel to the plane of the flip support frame 20. One end of the contour positioning block 41 has a strip-shaped hole whose length direction forms an angle with the second direction, and this strip-shaped hole forms a drive rail 45. The drive wheel 31 of the propulsion mechanism 30 is located in the drive rail 45, and when the propulsion mechanism 30 is in the first position, the drive wheel 31 is located at one end of the drive rail 45, and when the propulsion mechanism 30 is in the second position, the drive wheel 31 is located at the second end of the drive rail 45. Since the drive rail 45 forms an angle with the second direction, the change in position of the propulsion mechanism 30 can drive the contour positioning block 41 to move perpendicular to the flip support frame 20, and thus drive the contour positioning block 41 to move along the first direction. Specifically, taking the figure as an example, when the propulsion mechanism 30 moves from the first position to the second position, the contour positioning block 41 can move a preset distance to the left front of the flip support frame 20.

[0093] The contour positioning block 41 has a groove at the other end relative to the drive rail 45, preferably two grooves. The silicone pressure head 42 is connected to the contour positioning block 41, and its bottom protrudes from the bottom surface of the contour positioning block 41 through the through hole provided on the contour positioning block 41, thereby pressing the support when the flip support frame 20 is flipped into place.

[0094] The first positioning block 43 is connected to the contour positioning block 41 and is specifically set in the groove. The two connected side surfaces of the first positioning block 43 are adapted to the two side surfaces of the bracket. When the contour positioning block 41 moves along the first direction, the two side surfaces cooperate with the two side surfaces of the bracket to simultaneously achieve positioning of the bracket in two directions, thereby pushing the bracket to the precise position.

[0095] The second positioning block 44 is provided on both sides of the contour positioning block 41 and is adapted to be fitted and pressed with the two ends of the bracket. The second positioning block 44 is provided with positioning holes adapted to be fitted with the screw holes in the bracket. In this way, the locking mechanism can position the screw hole position of the bracket through the positioning hole of the second positioning block 44, thereby realizing the locking connection between the bracket and the housing.

[0096] In one embodiment, the system further includes a hinge base 80, which includes a hinge bracket 81 and a buffer portion. The hinge bracket 81 is fixed to the base 10, and a hinge pivot 82 is provided on the hinge bracket 81. The buffer portion is provided on the hinge bracket 81, and there are two buffer portions, which are respectively provided on both sides of the hinge pivot 82. The first end of the flip support frame 20 is provided with a flip bushing 21, which is connected to the hinge pivot 82 and can be flipped based on the hinge pivot 82. It can also abut against the buffer portion when flipped into position.

[0097] Specifically, the buffer part located on the side of the hinge shaft 82 away from the clamping block 11 is a buffer silicone pad 83, and the buffer part located on the side of the hinge shaft 82 facing the clamping block 11 is a hydraulic buffer 84.

[0098] For example, the hinge bracket 81 is also provided with a silicone anti-collision pad 85.

[0099] In one embodiment, the end of the flip sleeve 21 is provided with a first sensor, which is used to indicate that the flip is in place; the hinge bracket 81 is also provided with a second sensor 86, which is used to indicate that the flip is in place; the flip support frame 20 is also provided with a third sensor, which is used to sense that the drive wheel 31 has slid into place.

[0100] Specifically, the first sensor, the second sensor 86, and the third sensor can all be magnetic sensors. The flip sleeve 21 is equipped with a magnet, and the first and second sensors 86 are used to detect the magnets on the bottom and sides of the flip sleeve 21, respectively, to indicate that the flip is in place. The propulsion mechanism 30 is also equipped with a magnet, which, by adapting to the third sensor on the flip support frame 20, indicates that the propulsion mechanism 30, i.e., the sliding wheel, has slid into place.

[0101] Preferably, to reduce interference, the third sensor is disposed on the foolproof base 61 and is adapted to sense the magnet disposed at the bottom of the propulsion mechanism 30.

[0102] In one embodiment, a locking cylinder 90 is also included. The side of the flip support frame 20 has a positioning hole. The piston of the locking cylinder 90 can be inserted into the positioning hole when the first sensor, the second sensor 86, and the third sensor all indicate that the frame is in position. This further ensures that the flip support frame 20 is locked in place during flipping, preventing damage to the support and housing during subsequent operations.

[0103] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
