Description

Technical Field

[0001] The present disclosure relates to the field of tooling technology, and in particular to an assembly device. Background Art

[0002] Press-Fit technology is a connection formed by the elastic deformable pin or rigid pin and the metallized hole of the PCB. A close contact point is formed between the pin and the metallized hole, and electrical interconnection is achieved through mechanical connection.

[0003] When the circuit board is assembled with the housing, the Press-Fit pins on the circuit board need to be inserted into the pin holes of the housing. Therefore, a positioning column is usually set on the housing, and a positioning hole that cooperates with the positioning column is set on the circuit board. The circuit board is positioned by the cooperation between the positioning column and the positioning hole, so that the Press-Fit pins can be accurately inserted into the pin holes. However, due to the thickness of the housing, it is difficult to set the positioning column structure very long, which makes it difficult to achieve accurate positioning of the positioning holes and positioning column structures on the circuit board. When the number of pins is large and long, the pins are easy to touch the housing and be damaged when the circuit board and the housing are assembled.

[0004] Therefore, there is an urgent need for an assembly device for a circuit board and a housing to solve the above problems. Summary of the invention

[0005] In order to solve the above technical problems, the present disclosure provides an assembling device.

[0006] In a first aspect, the present disclosure provides an assembly device, including an assembly structure, wherein the assembly structure includes:

[0007] Lower support plate;

[0008] An upper pressing plate, located above the lower supporting plate and capable of moving in a vertical direction relative to the lower supporting plate;

[0009] A telescopic column, comprising an inner column and an outer column, wherein one end of the inner column is located in the inner cavity of the outer column and can extend or retract into the inner cavity, the outer column is connected to the upper pressing plate, and the outer diameter of the outer column is the same as the outer diameter of the inner column;

[0010] The support assembly includes a support column and an elastic support member, wherein the support column is installed on the lower support plate and is located below the upper pressure plate, and the elastic support member can provide a reverse force when subjected to pressure directed from the upper pressure plate to the lower support plate.

[0011] Optionally, the telescopic column further includes a second elastic member, which is disposed in the inner cavity, one end of the second elastic member abuts against one end of the inner column located in the inner cavity, and the second elastic member is compressed when the inner column retracts into the inner cavity.

[0012] Optionally, the telescopic column further includes a stud connected to the outer column, the stud is threadedly connected to the upper pressing plate, and the other end of the second elastic member abuts against the stud.

[0013] Optionally, the elastic support member includes a support sheet and a first elastic member, and the support sheet is rotatably connected to the support column;

[0014] When the support sheet is subjected to pressure directed from the upper pressure plate toward the lower support sheet, the first elastic member is deformed so that the support sheet provides a reverse force.

[0015] Optionally, the elastic support member further includes a fixing plate and a rotating shaft, the fixing plate is connected to the support column, the support plate and the fixing plate are rotatably connected via the rotating shaft, and the first elastic member is sleeved on the rotating shaft.

[0016] Optionally, at least two support assemblies are provided, and the two support assemblies are arranged opposite to each other and at intervals. The support assembly also includes an elastic limit block, and the elastic limit block is arranged on the support column.

[0017] Optionally, the support assembly further includes a mounting seat, the elastic limiting block and the fixing plate are both mounted on the mounting seat, and the mounting seat is mounted on the support column and can rotate around the axis direction of the support column.

[0018] Optionally, an insulating wear-resistant sheet is provided on the support sheet.

[0019] Optionally, the assembly device also includes a first loading structure, which includes a base plate and a positioning assembly, the base plate is detachably connected to the lower support plate, the base plate is provided with a slide rail and a slider slidably connected to the slide rail, and the positioning assembly is connected to the slider.

[0020] Optionally, the bottom plate is provided with limit blocks on both sides of the extending direction of the slide rail.

[0021] Optionally, the assembling device further comprises a second loading structure, wherein the second loading structure comprises a bearing assembly and a plurality of rollers arranged side by side on the bearing assembly.

[0022] Compared with the prior art, the technical solution provided by the embodiments of the present disclosure has the following advantages:

[0023] By setting a telescopic column, a lower support plate, an upper pressure plate and a support assembly, when assembling two assembly parts that cooperate with the positioning column through the positioning hole, the elastic support member of the support assembly supports the assembly part with the positioning hole, and the assembly part with the positioning column is placed on the lower support plate. The upper pressure plate moves downward so that the inner column of the telescopic column extends into the positioning hole. As the upper pressure plate moves downward, because the outer diameter of the outer column is larger than the outer diameter of the inner column, the outer column will push the assembly part with the positioning hole to move downward, and the elastic support member provides a reverse force for support and buffering. When the inner column contacts the positioning column, it retracts into the inner cavity of the outer column, and the outer column continues to push the assembly part to move downward along the axis of the inner column until the positioning column is inserted into the positioning hole. The inner column of the telescopic column plays the role of extending the positioning column, ensuring that the positioning hole and the positioning column can be accurately positioned, thereby avoiding the occurrence of offset when assembling the first assembly part and the second assembly part, which may cause damage to the remaining parts, and can improve assembly efficiency and save work time.

[0037] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0038] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0039] like Figures 1 to 7 As shown, an embodiment of the present disclosure provides an assembly device suitable for assembling a first assembly 10 and a second assembly 20, wherein a positioning column 101 is provided on the first assembly 10, and a positioning hole 201 cooperating with the positioning column 101 is provided on the second assembly 20. Exemplarily, the first assembly 10 is a shell, and the second assembly 20 is a circuit board with pins, wherein the pins are Press-Fit pins, and pin holes are provided on the shell corresponding to the pins, and when the circuit board and the shell are assembled, the pins extend into the pin holes. Of course, the first assembly 10 and the second assembly 20 can also be selected as other structures for positioning through the positioning column 101 and the positioning hole 201, which are not listed one by one here.

[0040] like Figure 1As shown, the above-mentioned assembly device includes an assembly structure 1, and the assembly structure 1 includes a lower support plate 11, an upper pressure plate 12, a telescopic column 13 and a support assembly 14. Among them, the upper pressure plate 12 is located above the lower support plate 11 and can move in the vertical direction relative to the lower support plate 11. The telescopic column 13 includes an inner column 131 and an outer column 132. One end of the inner column 131 is located in the inner cavity of the outer column 132 and can extend or retract into the inner cavity. The outer column 132 is connected to the upper pressure plate 12, and the outer diameter of the outer column 132 is greater than the outer diameter of the inner column 131. The support assembly 14 includes a support column 141 and an elastic support member 142. The support column 141 is installed on the lower support plate 11 and is located below the upper pressure plate 12. The elastic support member 142 can provide a reverse force when subjected to pressure directed from the upper pressure plate 12 to the lower support plate 11.

[0041] It can be understood that, by providing the telescopic column 13, the lower support plate 11, the upper pressing plate 12 and the supporting assembly 14, when assembling the first assembly 10 and the second assembly 20, the elastic support 142 of the supporting assembly 14 supports the second assembly 20, and as the upper pressing plate 12 moves downward, the inner column 131 extends into the positioning hole 201 of the second assembly 20, and the outer column 132 pushes the second assembly 20 to move downward, and the elastic supporting member 142 provides a reverse force to support and buffer the second assembly 20 until the inner column 131 contacts the positioning column 101 on the first assembly 10. When the second assembly 20 continues to move downward, the inner column 131 gradually retracts into the inner cavity of the outer column 132, and the telescopic column 13 plays the role of extending the positioning column 101 on the first assembly 10, ensuring that the positioning hole 201 and the positioning column 101 are accurately positioned, thereby avoiding the occurrence of offset when assembling the first assembly 10 and the second assembly 20, which may cause damage to other components, and can improve assembly efficiency and save work hours.

[0042] It should be noted that the outer diameter of the outer column 132 is greater than the diameter of the positioning hole 201 , so that it is difficult for the outer column 132 to be inserted into the positioning hole 201 .

[0043] like Figure 2 As shown, the telescopic column 13 also includes a second elastic member 133, which is disposed in the inner cavity of the outer column 132, and one end of the second elastic member 133 abuts against one end of the inner column 131 located in the inner cavity. When the inner column 131 retracts into the inner cavity, the second elastic member 133 is compressed. The second elastic member 133 is preferably a spring. It can be understood that when the upper pressing plate 12 drives the telescopic column 13 to move downward, and the inner column 131 contacts the positioning column 101 on the first assembly 10, as the upper pressing plate 12 continues to move downward, the inner column 131 compresses the second elastic member 133 and gradually retracts into the inner cavity. When the upper pressing plate 12 moves upward, the inner column 131 is out of contact with the positioning column 101 on the first assembly 10, and under the action of the second elastic member 133, the inner column 131 extends out of the inner cavity again, thereby achieving the reset of the inner column 131.

[0044] It should be noted that in order to prevent the inner column 131 from escaping from the inner cavity of the outer column 132, the inner column 131 is configured as a T-shaped column, and the cooperation between the T-shaped column and the through hole opened on the outer column 132 realizes the limitation of the inner column 131, and the through hole is connected to the inner cavity of the outer column 132.

[0045] Further, the telescopic column 13 also includes a stud 134 connected to the outer column 132, the stud 134 is threadedly connected to the upper pressing plate 12, and the other end of the second elastic member 133 abuts against the stud 134. It can be understood that by providing the stud 134, the stud 134 is threadedly connected to the upper pressing plate 12, and the distance between the telescopic column 13 and the second assembly 20 can be adjusted by screwing the stud 134 to adapt to different first assemblies 10 and second assemblies 20. In addition, the stud 134 can also be threadedly connected to the outer column 132, so as to facilitate the assembly of the telescopic column 13.

[0046] In addition, the positioning holes 201 with different apertures can be adapted by replacing the telescopic columns 13 with different diameters of the inner columns 131. That is, when the apertures of the positioning holes 201 of different first assemblies 10 are different, the telescopic columns 13 can be replaced to adapt, thereby expanding the scope of use of the assembly device.

[0047] like Figure 1 As shown, the assembly structure 1 also includes a spring guide column 15 disposed between the upper pressure plate 12 and the lower support plate 11. The spring guide column 15 includes a guide outer column, a guide inner column and a spring. One end of the guide inner column is connected to the upper pressure plate 12, and the other end extends into the inner cavity of the guide outer column. The guide outer column is connected to the lower support plate 11. The spring is sleeved on the guide inner column, and one end abuts against the upper pressure plate 12, and the other end abuts against the guide outer column. In this way, the upper pressure plate 12 can be buffered when it moves downward, and when the upper pressure plate 12 is not under pressure, the spring pushes the upper pressure plate 12 back to its original position.

[0048] Furthermore, the assembly structure 1 further comprises a guide post 16 disposed on the lower support plate 11, and the guide post 16 is disposed through the upper pressing plate 12. The guide post 16 is disposed vertically to guide the movement of the upper pressing plate 12 to prevent the upper pressing plate 12 from deflecting when moving.

[0049] Further, in order to facilitate the operation of the upper pressing plate 12, an armrest 121 is provided on the upper pressing plate 12, and the operator can press down the upper pressing plate 12 through the armrest 121. Optionally, the upper pressing plate 12 can also be pressed down by a driving structure, such as a cylinder, an electric push rod, etc., which is not specifically limited here.

[0050] like Figure 3 and Figure 4The elastic support member 142 includes a support sheet 1422 and a first elastic member 1423, and the support sheet 1422 is rotatably connected to the support column 141; when the support sheet 1422 is subjected to pressure directed from the upper pressure plate 12 to the lower support plate 11, the first elastic member 1423 is deformed so that the support sheet 1422 provides a reverse force.

[0051] It can be understood that the support sheet 1422 can support the second assembly 20. When the second assembly 20 moves downward, the support sheet 1422 is pushed to rotate relative to the support column 141. The support sheet 1422 provides a reverse force under the action of the first elastic member 1423, thereby supporting and cushioning the second assembly 20 when the second assembly 20 moves downward.

[0052] It should be noted that, in a natural state, the support sheet 1422 is arranged horizontally. The support sheet 1422 can rotate between horizontal and vertical relative to the support column 141. When the support sheet 1422 is horizontal, it can support the second assembly 20. When the support sheet 1422 is vertical, the second assembly 20 can be given way so that the second assembly 20 and the first assembly 10 are assembled. In the process of changing from horizontal to vertical, the support sheet 1422 can support and buffer the second assembly 20 to prevent the second assembly 20 from falling when moving downward, and the first elastic member 1423 is deformed so that the support sheet 1422 can rotate from vertical to horizontal, thereby facilitating the next assembly.

[0053] like Figure 3 and Figure 4 As shown, the elastic support member 142 further includes a fixing plate 1421 and a rotating shaft 1424 . The fixing plate 1421 is connected to the support column 141 . The support plate 1422 and the fixing plate 1421 are rotatably connected via the rotating shaft 1424 . The first elastic member 1423 is sleeved on the rotating shaft 1424 .

[0054] It can be understood that the support plate 1422 has a first position and a second position relative to the fixed plate 1421. In a natural state, the support plate 1422 is located at the first position, at which the support plate 1422 is horizontally arranged to support the second assembly 20; when the support plate 1422 is located at the second position, the support plate 1422 is vertically arranged; the first elastic member 1423 is deformed when the support plate 1422 rotates from horizontal to vertical, and the deformation of the first elastic member 1423 provides a restoring force for the support plate 1422 to rotate from vertical to horizontal.

[0055] It can be understood that when the support sheet 1422 is located at the first position, the support sheet 1422 can support the second assembly 20. When the second assembly 20 is pushed downward by the telescopic column 13 on the upper pressing plate 12, the support sheet 1422 moves from the first position to the second position, that is, rotates from horizontal to vertical. Due to the action of the first elastic member 1423, the support sheet 1422 can not only support the second assembly 20, but also buffer the downward movement of the second assembly 20 until the support sheet 1422 moves to the second position, and the second assembly 20 is separated from the support sheet 1422. Subsequently, when the upper pressing plate 12 is no longer subjected to external force and moves upward under the action of the spring guide column 15, the support sheet 1422 moves from the second position to the first position under the action of the first elastic member 1423, that is, rotates from vertical to horizontal.

[0056] For example, refer to Figure 4 The first elastic member 1423 is preferably a torsion spring, which is sleeved on the rotating shaft 1424, and two free ends of the torsion spring are respectively in contact with the supporting plate 1422 and the fixing plate 1421.

[0057] Furthermore, at least two support assemblies 14 are provided, wherein the two support assemblies 14 are arranged opposite to each other and at intervals, and the support assemblies 14 further include elastic stop blocks 143, which are arranged on the support columns 141. By providing the elastic stop blocks 143, the first assembly 20 can be limited on two opposite sides of the second assembly 20, so as to prevent the second assembly 20 from shifting when being assembled with the first assembly 10, and the use of the elastic stop blocks 143 can prevent the second assembly 20 from being damaged.

[0058] Furthermore, the supporting assembly 14 includes two elastic limiting blocks 143 , and the two elastic limiting blocks 143 are arranged at an interval.

[0059] Preferably, the elastic limit block 143 is made of wear-resistant and elastic materials such as TPU (Thermoplastic polyurethanes) or TPE (Thermoplastic Elastomer).

[0060] Specifically, when the second assembly 20 is a rectangular plate-like structure, such as a circuit board, the support sheet 1422 extends along the length direction of the circuit board, the elastic limit block 143 limits the circuit board in the width direction of the circuit board, and the two elastic limit blocks 143 on each support component 14 are spaced apart in the length direction of the circuit board.

[0061] Furthermore, the support assembly further includes a mounting seat 144, the elastic stopper 143 and the fixing plate 1421 are both mounted on the mounting seat 144, and the mounting seat 144 is mounted on the support column 141 and can rotate around the axis direction of the support column 141. In this way, the positions of the support plate 1422 and the elastic stopper 143 can be adjusted according to the shape of the second assembly 20.

[0062] Specifically, refer to Figure 3 The support column 141 is provided with a protruding column, and the mounting seat 144 is provided with a through hole for the protruding column to extend into. The mounting seat 144 and the protruding column are relatively fixed by screws or bolts that penetrate the mounting seat 144. When the mounting seat 144 needs to be rotated, the screws or bolts can be loosened, and then the angle of the mounting seat 144 can be adjusted, and finally the screws or bolts can be tightened to achieve relative fixation between the mounting seat 144 and the protruding column.

[0063] Optionally, the height of the support column 141 is adjustable, so that the distance between the second assembly 20 and the upper pressing plate 12 can be adjusted, which is convenient for assembling different second assemblies 20. When the second assembly 20 is a circuit board, it can also adapt to the situation when the length of the pins on the circuit board changes. The support column 141 can use a telescopic column to achieve height adjustment, and the height adjustment of the support column 141 can also be achieved by replacing the support column 141 of different lengths, which is not specifically limited here.

[0064] Optionally, the position of the support column 141 on the lower support plate 11 is adjustable, so as to facilitate adapting to second assembly members 20 of different sizes.

[0065] Furthermore, an insulating wear-resistant sheet 1425 is provided on the support sheet 1422. By providing the insulating wear-resistant sheet 1425, the service life of the support sheet 1422 is increased, thereby increasing the service life of the elastic support member 142, and when the second assembly 20 is a circuit board, the insulating wear-resistant sheet 1425 can prevent static electricity and avoid damage to the circuit board caused by static electricity breakdown.

[0066] For example, in some embodiments, at least two support assemblies 14 are provided. Figure 1 , there are four support components 14, and the four support components 14 are arranged in pairs. Taking the second assembly 20 as a circuit board as an example, the above support components 14 are provided with four, and the four support components 14 are arranged in pairs, and the two groups of support components 14 are respectively located on both sides of the length or width direction of the circuit board to stably support the circuit board.

[0067] For example, in some other embodiments, one support assembly 14 may be provided. For example, for a second assembly 20 with a through hole in the middle, the second assembly 20 may be supported by one support assembly 14, and the support column 14 is directly opposite to the through hole of the second assembly 20. Furthermore, the support column 141 may be provided with one or two elastic support members 142.

[0068] like Figure 5 and Figure 6 As shown, the assembly device further includes a first loading structure 3, which is used for loading the first assembly 10 and for unloading the first assembly 10 and the second assembly 20 after the assembly is completed.

[0069] Reference Figure 6 The first loading structure 3 includes a base plate 31 and a positioning assembly 32 . The base plate 31 is detachably connected to the lower support plate 11 . A slide rail 311 and a slider 312 slidably connected to the slide rail 311 are provided on the base plate 31 . The positioning assembly 32 is connected to the slider 312 .

[0070] It is understandable that the first assembly 10 can be positioned by the positioning component 32 , and because the slider 312 and the slide rail 311 are provided on the bottom plate 31 , the position of the first assembly 10 can be adjusted so that the first assembly 10 moves to the bottom of the second assembly 20 .

[0071] It should be noted that the positioning component 32 can be used to position the first assembly 10 by means of a clamping or screw fixing method, which is not specifically limited herein. In addition, the positioning component 32 can be replaced to adapt to different second assemblies 20 .

[0072] Furthermore, a pull-out handle 314 is also provided on the slider 312. When the first assembly 10 and the second assembly 20 need to be assembled, the slider 312 is pushed by the pull-out handle 314 to move the first assembly 10 to the bottom of the second assembly 20. When the first assembly 10 and the second assembly 20 are assembled, the slider 312 can be pulled by the pull-out handle 314 to move the assembled first assembly 10 and the second assembly 20, so that the assembled first assembly 10 and the second assembly 20 are moved out from under the upper pressing plate 12, so that the assembled first assembly 10 and the second assembly 20 can be easily removed.

[0073] Furthermore, the bottom plate 31 is provided with limit blocks 313 on both sides of the extending direction of the slide rail 311. By providing the limit blocks 313, the slider 312 can be limited when moving, ensuring that the first assembly 10 is located at a preset position, which facilitates the assembly of the first assembly 10 and the second assembly 20.

[0074] like Figure 5 and Figure 7As shown, the assembly device further comprises a second loading structure 2, which is used for loading the second assembly 20. The second loading structure 2 comprises a bearing assembly 21 and a plurality of rollers 22 arranged side by side on the bearing assembly 21.

[0075] Furthermore, the second loading structure 2 further includes a carrier plate 23, and the second assembly 20 is positioned on the carrier plate 23, and the second assembly 20 is transported by moving the carrier plate 23 on the roller 22. When the second assembly 20 is a circuit board, since the pins on the circuit board face downward when the circuit board is assembled with the housing, support protrusions 24 are provided at the four corners of the carrier plate 23 to support the circuit board so that the pins are suspended in the air to avoid damage to the pins on the circuit board.

[0076] It should be noted that the second loading structure 2 can also use a robot arm or the like to load the circuit board, which will not be listed here one by one.

[0077] The working process of the assembly device will be described in detail below.

[0078] Step 1: Load the second assembly 20 to the support component 14 through the second loading structure 2. The support sheet 1422 of the support component 14 supports the second assembly 20. At this time, the second assembly 20 is located below the upper pressing plate 12, and the telescopic column 13 on the upper pressing plate 12 is facing the positioning hole 201 on the second assembly 20.

[0079] Step 2: Position the first assembly 10 on the first loading structure 3 through the positioning component 32, and push the slider 312 by pulling the handle 314 to move the first assembly 10 below the second assembly 20, and limit the position of the slider 312 by the limit block 313 to ensure that the second assembly 20 is located at the preset position.

[0080] Step 3, the upper pressing plate 12 is pressed down by the handrail 121, and the inner column 131 of the telescopic column 13 first extends into the positioning hole 201 of the second assembly 20, and then the outer column 132 of the telescopic column 13 pushes the second assembly 20 to move downward. During the downward movement, the second assembly 20 pushes the support sheet 1422 to move from horizontal to vertical. At this time, the support sheet 1422 plays the role of supporting the second assembly 20. After the inner column 131 contacts the positioning column 101 on the first assembly 10, as the upper pressing plate 12 is pressed down, the inner column 131 gradually retracts to the inner cavity of the outer column 132 until the positioning column 101 of the first assembly 10 extends into the positioning hole 201 of the second assembly 20. At this time, the support sheet 1422 moves to the second position, and the first assembly 10 and the second assembly 20 are assembled. Then, the support sheet 1422 rotates from vertical to horizontal under the action of the second elastic member 1423.

[0081] Step 4: Release the upper pressing plate 12, which moves upward and returns to its original position under the action of the spring of the spring guide pillar 15.
