Description

Technical Field

[0001] This invention relates to the field of light guide post assembly technology, and in particular to a device and method for assembling light guide posts. Background Technology

[0002] With the continuous development of electronic devices, light guides, as a common optical component, are widely used in various electronic devices to conduct light from light-emitting elements (such as LEDs) on circuit boards to the outside of the device casing to indicate the working status of the device.

[0003] Light guides typically have a connector and prongs extending outwards from the connector. During assembly, the prongs need to be accurately aligned and inserted into the corresponding slots on the circuit board. Currently, light guide assembly is mostly done manually or by applying pressure directly with simple pneumatic fixtures. However, because the prongs of the light guides are small and brittle, manual pressing makes it difficult to ensure that the force direction is always perpendicular to the circuit board, easily leading to the prongs tilting, bending, or even breaking. Furthermore, uneven pressure from manual pressing can cause the prongs to not be inserted properly or damage the circuit board due to excessive force. Existing simple fixtures often lack precise guiding and positioning mechanisms, making the light guides prone to shifting or wobbling during the pressing process, resulting in low assembly yield and difficulty in improving production efficiency. Summary of the Invention

[0004] The purpose of this invention is to overcome the low yield rate of light guide post assembly in the prior art, and to provide a device and method for assembling light guide posts.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: This invention provides a device for assembling a light guide post. The light guide post has a connector and a pin connected to the connector. The pin is used to connect to a slot on a circuit board. The device includes a positioning seat and a movable mold. The positioning seat has a positioning groove for accommodating and positioning the connector and a guide channel communicating with the positioning groove. The guide channel is arranged along the Z direction. The movable mold extends into the guide channel and slides along the guide channel to push the connector in the positioning groove to move along the Z direction toward the circuit board to press the pin into the slot.

[0006] Furthermore, the movable mold is connected to a limiting member arranged along the X direction, and the positioning seat is provided with a limiting groove in the X direction that communicates with the guide channel. The limiting member extends into the limiting groove in the X direction and slides in the limiting groove in the Z direction.

[0007] Furthermore, two limiting grooves are provided and are symmetrically arranged on both sides of the guide channel in the X direction; the limiting member is provided corresponding to the limiting groove.

[0008] Furthermore, the two limiting grooves pass through the positioning seat at both ends in the X direction; the limiting member is a pin, and the movable mold is provided with a connecting hole, the pin passes through the limiting groove and is inserted into the connecting hole.

[0009] Furthermore, an opening is provided on one side wall of the positioning groove in the Y direction. When the connecting seat is placed in the positioning groove, the connecting seat cooperates with the positioning groove, and the main body of the light guide post extends out of the positioning groove from the opening.

[0010] Furthermore, the width of the opening in the X direction is smaller than the width of the positioning groove in the X direction.

[0011] Furthermore, both sides of the positioning groove in the X direction are provided with elastic layers.

[0012] Furthermore, the positioning seat includes a positioning block, a first support leg, and a second support leg; the first support leg and the second support leg are arranged side by side and are both connected to the same end of the positioning block in the Z direction to balance and support the positioning block; the guide channel and the positioning groove together pass through the positioning block and the first support leg.

[0013] Furthermore, the second leg is arranged side by side with the first leg in the Y direction, and the second leg is positioned away from the opening.

[0014] This invention also provides a method for assembling a light guide post, based on the apparatus for assembling a light guide post as described above, comprising: Position the connector in the positioning groove and align the pins with the slots on the circuit board. Place the positioning base smoothly onto the circuit board; Apply force to the movable mold to make it slide along the guide channel and push the connector towards the circuit board so that the pin is inserted into the slot; Once the pins are fully inserted into the slots, stop applying force to the movable mold and remove the positioning seat from the circuit board.

[0015] The device and method for assembling light guide pillars of the present invention have the following advantages compared with the prior art: by setting a positioning seat with a positioning groove and a guide channel, and a movable mold that slides in the guide channel, the connecting seat of the light guide pillar is positioned in the positioning groove before pressing. Then, the movable mold slides down the guide channel precisely to push the connecting seat, so that the plug pin can always be pressed into the slot of the circuit board in the vertical direction of the Z-axis, effectively avoiding bending or damage to the plug pin due to tilting under force, and greatly improving the assembly accuracy and yield of the light guide pillar.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. In addition, those skilled in the art can combine and integrate the different embodiments or examples described in this specification.

[0027] In the description of this specification, it should be understood that the terms "Z-direction," "X-direction," "Y-direction," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the 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, and therefore should not be construed as a limitation of the invention. Specifically, the Z-direction generally refers to the vertical direction (up and down direction), and the X-direction and Y-direction generally refer to mutually perpendicular horizontal directions, and the X-direction, Y-direction, and Z-direction are mutually perpendicular.

[0028] See Figures 1 to 7 As shown, this embodiment of the invention provides a device for assembling a light guide post 1. The light guide post 1 has a connecting seat 11 and a plug pin 12 connected to the connecting seat 11. The plug pin 12 is used to connect to a slot 21 on a circuit board 2. The device includes a positioning seat 3 and a movable mold 4. The positioning seat 3 is provided with a positioning groove 31 for accommodating and positioning the connecting seat 11 and a guide channel 32 communicating with the positioning groove 31. The guide channel 32 is arranged along the Z direction. The movable mold 4 extends into the guide channel 32 and slides along the guide channel 32 to push the connecting seat 11 in the positioning groove 31 to move towards the circuit board 2 along the Z direction to press the plug pin into the slot 21.

[0029] Specifically, during assembly, the light guide post 1 is first placed into the positioning groove 31 for positioning. At this time, the connector pin 12 is located entirely or partially within the positioning groove 31, facing away from the guide channel 32. Then, the entire device is moved above the circuit board 2, aligning the connector pin 12 with the slot 21. Next, the movable mold 4 is driven (either manually pressed or driven by a cylinder or other drive source). The movable mold 4 is constrained by the guide channel 32 along the Z-direction and slides straight down, pressing against the connector seat 11 and applying a downward thrust, precisely and vertically pressing the connector pin 12 into the slot 21. This process effectively avoids bending or damage to the connector pin 12 due to tilting under force, significantly improving assembly accuracy and yield.

[0030] It is understandable that the end face of the movable mold 4 used to contact the connecting seat 11 is not limited to a single planar structure, but can be adaptively matched according to the actual shape of the top surface of the connecting seat 11. For example, when there is a height difference or irregular structure on the top surface of the connecting seat 11, the contact end face of the movable mold 4 can be set to a corresponding stepped shape, or other shapes that facilitate balanced force application to the connecting seat 11. The advantage of this end face conformal design is that when the movable mold 4 is pressed down, its end face can achieve a large-area contact with the top surface of the connecting seat 11, thereby ensuring that the pressing force is evenly distributed and avoiding problems such as the skewing of the connecting seat 11 or the bending of the plug pin 12 caused by local force or eccentric pressure, further improving the stability of the pressing process and the assembly success rate.

[0031] Preferably, the cross-section of the guide channel 32 in the XY plane completely overlaps with the cross-section of the positioning groove 31 in the XY plane. This design of completely overlapping cross-sections means that the guide channel 32 and the positioning groove 31 have completely identical dimensions in the horizontal projection and their boundaries are aligned with each other. Together, they form a continuous straight channel with a flat inner wall and no steps or narrowing obstructions. When the movable mold 4 pushes the connecting seat 11 to move along the Z direction, the movable mold 4 will not be interfered with or stuck by any side wall steps during the smooth transition from the guide channel 32 to the positioning groove 31. At the same time, this structure also makes the processing of the inner cavity of the positioning seat 3 simpler. For example, it can be formed in one go by wire cutting and other processes, which not only improves the processing efficiency, but also ensures the high precision and consistency of the inner cavity dimensions, thereby greatly improving the fitting accuracy between the movable mold 4 and the guide channel 32 and the positioning groove 31.

[0032] Furthermore, the movable module 4 is connected to a limiting member 5 arranged along the X direction, and the positioning seat 3 is provided with a limiting groove 33 in the X direction that communicates with the guide channel 32. The limiting member 5 extends into the limiting groove 33 in the X direction and slides in the limiting groove 33 in the Z direction.

[0033] Specifically, the limiting groove 33 provides a clear movement trajectory for the limiting component 5, restricts the rotational freedom of the movable mold 4 during the sliding process, and prevents the movable mold 4 from deflecting within the guide channel 32; at the same time, the two ends of the limiting groove 33 play a role in limiting the stroke, effectively preventing the movable mold 4 from accidentally coming out of the guide channel 32 during the sliding process, thereby ensuring the stability and safety of the pressing process.

[0034] Furthermore, two limiting grooves 33 are provided and are symmetrically arranged on both sides of the guide channel 32 in the X direction; the limiting member 5 is provided corresponding to the limiting grooves 33.

[0035] Specifically, the symmetrical arrangement of the structural design has significant mechanical advantages. When the movable mold 4 slides in the guide channel 32, the symmetrical limiting parts 5 on both sides can provide balanced lateral constraint force, avoiding the phenomenon of the movable mold 4 jamming, deflection or uneven wear caused by uneven force on one side. This further ensures the linearity and stability of the movement trajectory of the movable mold 4 and extends the service life of the device.

[0036] Furthermore, the two limiting grooves 33 pass through the positioning seat 3 at both ends in the X direction; the limiting member 5 is a pin, and the movable mold 4 is provided with a connecting hole 41 (not shown in the figure). The pin passes through the limiting groove 33 and is inserted into the connecting hole 41.

[0037] Specifically, a connecting hole 41 is provided on the movable mold 4. During installation, the pin passes through the limiting groove 33 on one side of the positioning seat 3, inserts into the connecting hole 41 of the movable mold 4, and its other end extends into the limiting groove 33 on the opposite side of the positioning seat 3. This through-type pin structure is not only easy to process and has low manufacturing cost, but also greatly facilitates the disassembly and maintenance of the device; as a standard part, the pin has strong versatility, and at the same time, it realizes efficient and reliable locking and limiting of the movable mold 4.

[0038] Furthermore, an opening 34 is provided on one side wall of the positioning groove 31 in the Y direction. When the connecting seat 11 is placed in the positioning groove 31, the connecting seat 11 cooperates with the positioning groove 31, and the main body of the light guide post 1 extends out of the positioning groove 31 from the opening 34.

[0039] Specifically, this embodiment improves the positioning groove 31 to accommodate the special structure of the light guide post 1. Considering that the light guide post 1 not only has a connecting seat 11 and a plug pin 12, but also typically has a main body for guiding light, an opening 34 is provided on one side wall of the positioning groove 31 in the Y direction. When the connecting seat 11 is placed inside the positioning groove 31 and positioned in conjunction with it, the main body of the light guide post 1 can extend out of the positioning groove 31 through this opening 34. This design cleverly avoids the irregular shape of the light guide post 1, allowing the device to adapt to the structure of the light guide post 1 with a laterally extended main body, expanding the applicability of the device and avoiding interference between the main body of the light guide post 1 and the device.

[0040] Furthermore, the width of the opening 34 in the X direction is smaller than the width of the positioning groove 31 in the X direction.

[0041] Specifically, the width of the opening 34 in the X direction is smaller than the width of the positioning groove 31 in the X direction. This tapered design creates a buckle-like blocking structure on the sidewall of the opening 34. When the connector 11 is placed into the positioning groove 31, the sidewalls on both sides of the opening 34 can limit and block the connector 11 in the X direction, effectively preventing the connector 11 from accidentally coming out of the opening 34 before being pressed down. This ensures the positional stability of the light guide post 1 before pressing and improves the ease of operation.

[0042] Furthermore, elastic layers 6 are provided on both sides of the positioning groove 31 in the X direction.

[0043] Specifically, when the connector 11 is placed into the positioning groove 31, the elastic layers 6 on both sides are compressed and deformed, thereby applying a flexible clamping force to the connector 11. This design not only eliminates the fit gap between the connector 11 and the positioning groove 31, preventing the connector 11 from shaking and enhancing the reliability of positioning, but also the flexible contact of the elastic layers 6 can effectively avoid scratches or damage to the surface of the connector 11 caused by hard compression, ensuring the appearance quality of the product.

[0044] Furthermore, the positioning base 3 includes a positioning block 35, a first support leg 36, and a second support leg 37; the first support leg 36 and the second support leg 37 are arranged side by side and are both connected to the same end of the positioning block 35 in the Z direction to balance and support the positioning block 35; the guide channel 32 and the positioning groove 31 together pass through the positioning block 35 and the first support leg 36.

[0045] Specifically, the first leg 36 and the second leg 37 are arranged side by side and both connected to the same end of the positioning block 35 in the Z direction, forming a bridge-like support structure to balance and support the positioning block 35. The guide channel 32 and the positioning groove 31 run through the positioning block 35 and the first leg 36. This structural design provides a stable operating platform for the press-fitting operation. The first leg 36 and the second leg 37 can be stably supported on the circuit board 2 or the worktable, ensuring that the positioning block 35 does not shake during the press-fitting process. At the same time, the through-channel design provides unobstructed space for the insertion pin 12 and the connecting seat 11 to fall, ensuring smooth and unimpeded press-fitting. In addition, the gap formed between the first leg 36 and the second leg 37, which are arranged side by side, can also effectively avoid components on the circuit board 2, preventing interference between the device and higher components on the surface of the circuit board 2 during the press-fitting process, thereby improving the versatility of the device on circuit boards 2 with different layouts.

[0046] Furthermore, the second leg 37 is arranged side by side with the first leg 36 in the Y direction, and the second leg 37 is located away from the opening 34.

[0047] Specifically, the second leg 37 and the first leg 36 are arranged side by side in the Y direction. This arrangement optimizes the spatial distribution on the side of the positioning seat 3, ensuring that the pin has sufficient operating space when it is inserted, installed or removed, and avoiding interference between the legs and the pin in the axial direction or operating path, thus facilitating the operation of the pin. At the same time, the second leg 37 is located away from the opening 34, that is, the side where the opening 34 is located remains relatively open and there is no obstruction from the legs. This structural design makes the area of ​​the opening 34 completely exposed, allowing the operator to perform actions such as inserting, aligning and removing the light guide column 1 without any obstruction, thus facilitating the operation of the light guide column 1 and effectively improving the smoothness of the assembly process.

[0048] Furthermore, the positioning block 35, the first support leg 36, and the second support leg 37 are integrally formed structures.

[0049] Specifically, this one-piece molded structure can be integrally formed by CNC machining of metal or by injection molding. The one-piece molded structure eliminates the connection gaps and assembly errors between the components, significantly improving the overall structural rigidity and strength of the positioning seat 3, enabling it to withstand repeated pressing forces; at the same time, this process also simplifies the production process, reduces processing costs, and improves product manufacturing efficiency.

[0050] See Figure 8 The present invention also provides a method for assembling a light guide post, based on the apparatus for assembling a light guide post as described above, including the following steps S1 to S4: S1. Position the connector in the positioning groove and align the pins with the slots on the circuit board.

[0051] The design principle of this step is to establish the vertical reference of the light guide column 1 before force is applied by cooperating with the positioning groove 31 and the connector 11, so as to prevent the plug pin 12 from tilting when subjected to force. In terms of specific execution, the operator can flexibly choose two modes according to the actual situation: one is to first place the connector 11 into the positioning groove 31 and clamp it in position, and then move the whole assembly above the circuit board 2 so that the plug pin 12 is aligned with the slot 21. This is particularly suitable for assembling light guide columns 1 with long or soft plug pins 12 that are prone to tilting due to their own weight; the other is to first align the plug pin 12 with the slot 21 and make the light guide column 1 stand up on the circuit board 2, and then align the positioning groove 31 of the positioning seat 3 with the connector 11 and put it on to straighten the light guide column 1, which may have been slightly tilted, making it easier to position the plug pin 12 and the positioning seat 3.

[0052] S2. Place the positioning base stably on the circuit board.

[0053] In practice, the operator must ensure that the support surface at the bottom of the positioning base 3, such as the first leg 36 and the second leg 37, is fully in contact with the surface of the circuit board 2, and that there is no lateral slippage or tilting during placement. In this step, the stable support base can reliably withstand the reaction force generated when the movable mold 4 is pressed down, ensuring that the pressing force is entirely converted into an effective thrust along the Z direction, further guaranteeing the stability and safety of the pin 12 vertically entering the slot 21.

[0054] S3. Apply force to the movable mold to make it slide along the guide channel and push the connector towards the circuit board so that the pin is inserted into the slot.

[0055] In practice, the operator uses manual pressure rods, pressure presses, or other auxiliary force-applying tools to press the top of the movable mold 4. Alternatively, the top of the movable mold 4 can be connected to the output of an automated drive device such as a pneumatic or electric cylinder, providing continuous and stable downward pressure. Under this thrust, the movable mold 4, constrained by the guide channel 32, can only slide down in a straight line. Its bottom end contacts the top surface of the connecting seat 11 and pushes the connecting seat 11 to overcome resistance and move downward, thereby smoothly driving the insertion pin 12 into the slot 21. This step, through the guide channel 32, eliminates the adverse effects of human force direction deviation or lateral vibration of the equipment, ensuring that the connecting seat 11 is subjected to uniform force and is absolutely perpendicular, allowing the insertion pin 12 to slide smoothly and without damage into the depth of the slot 21, fundamentally preventing the insertion pin 12 from bending or breaking.

[0056] S4. When the pin is fully inserted into the slot, stop applying force to the moving mold and remove the positioning seat from the circuit board.

[0057] In practice, once the operator senses that the connector pin 12 has been installed in place or determines that the stroke has ended through the structure of the limiting groove 33, the force applied to the movable mold 4 is immediately released. Then, the positioning seat 3 is lifted upward along the Z direction, allowing the positioning groove 31 to smoothly disengage from the already assembled connecting seat 11. This step precisely controls the pressing stroke, preventing the connector pin 12 from being excessively pressed and damaging or crushing the solder pads of the circuit board 2.

[0058] The above embodiments are preferred implementations of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious substitutions without departing from the concept of the present technical solution are within the protection scope of the present invention.
