Description

Technical Field

[0001] This application relates to the field of pressing technology, specifically to a pressing device. Background Technology

[0002] In the assembly of electronic products, it is often necessary to press small parts onto large parts. Traditional pressing methods typically use equipment such as pressing machines to press pre-stacked small and large parts together. However, when it is necessary to mount small parts onto the side walls of large parts, it is difficult to accurately place the small parts in their corresponding mounting positions on the large parts beforehand. In addition, when using traditional pressing machines, it is difficult to precisely control the degree of pressing, which can easily lead to incomplete pressing or over-pressing; at the same time, other structures of the large parts (such as side walls in other locations) may interfere with the pressing operation, resulting in problems such as pressing misalignment. Utility Model Content

[0003] In view of the above, it is necessary to propose a pressing device that can accurately press the first workpiece onto the second workpiece and facilitate control of the pressing degree.

[0004] This application provides a pressing device for pressing a first workpiece onto a second workpiece, comprising: a positioning mechanism, the positioning mechanism including a support base and a positioning component, the support base having a loading position for supporting the second workpiece, the positioning component being arranged around the loading position and configured to position the second workpiece; and a pressing mechanism including a pressing component and a driving component, the pressing component including a connecting sleeve, a sliding shaft, a pressing head, and a limiting component, the connecting sleeve being detachably connected to the positioning component, and the sliding shaft being slidably connected to the connecting sleeve. One end of the slide shaft near the loading position protrudes from the connecting sleeve and is provided with the limiting member. The pressure head is disposed at one end of the slide shaft near the loading position and facing the positioning component. The pressure head is configured to carry the first workpiece. The driving component is connected to one end of the slide shaft away from the loading position and is used to drive the slide shaft to slide along the connecting sleeve, so that the slide shaft drives the pressure head to move toward the positioning component, thereby assembling the first workpiece onto the second workpiece. The limiting member is configured to abut against the connecting sleeve to limit the movement distance of the slide shaft.

[0005] The aforementioned pressing equipment, through the cooperation of the support base and positioning component of the positioning mechanism, can position the second workpiece, improving the pressing stability and accuracy. The pressing component in the pressing mechanism can be installed on the positioning component, and the connecting sleeve in the pressing component is detachably connected to the positioning component, serving to connect and adjust the position. When multiple first workpieces need to be pressed onto the second workpiece, the position of the connecting sleeve connected to the positioning component can be adjusted so that the sliding shaft and pressing head correspond to the position of the first workpiece to be installed on the second workpiece. The pressing head is used to carry the first workpiece. The drive component can drive the sliding shaft to slide along the connecting sleeve, thereby moving the pressing head and the first workpiece toward the position of the first workpiece to be installed on the second workpiece, until the pressing head presses the first workpiece onto the second workpiece. Precise alignment of the pressing position improves pressing accuracy. During pressing, the limiting component connected to the sliding shaft abuts against the connecting sleeve, thereby limiting the sliding shaft's movement distance, and thus limiting the degree to which the pressing head presses the first workpiece, avoiding incomplete or excessive pressing, facilitating control of the pressing degree, and further ensuring pressing accuracy.

[0006] In some embodiments, the sliding shaft has a receiving hole at one end near the material loading position. The limiting member includes a plug-in end and a limiting end disposed opposite to each other.

The cross-section of the plug-in end is a regular polygon adapted to the receiving hole. The cross-section of the limiting end is a polygon corresponding to the plug-in end, and the cross-sectional area of ​​the limiting end is larger than the cross-sectional area of ​​the plug-in end. Each side of the limiting end corresponds one-to-one with each side of the plug-in end, and the distance between each side of the limiting end and its corresponding side of the plug-in end is different.

[0007] In some embodiments, the positioning assembly includes two support positioning members, both disposed on the support base, the two support positioning members being spaced apart on both sides of the material loading position, the two support positioning members cooperating to position the second workpiece, each support positioning member having a positioning groove spaced apart along a direction perpendicular to the sliding shaft on its side away from the support base; the outer wall of the connecting sleeve has a positioning protrusion adapted to the positioning groove, the positioning protrusion being configured to be inserted into the positioning groove to position the connecting sleeve.

[0009] In some embodiments, the drive assembly includes a flange and a drive handle. The flange is threadedly connected to one end of the slide shaft away from the loading position. The drive handle is connected to the flange and is used to drive the flange to rotate, thereby driving the slide shaft to slide. The slide shaft drives the pressure head to move toward the positioning assembly, thereby assembling the first workpiece onto the second workpiece.

[0010] In some embodiments, the slide shaft has an extension extending toward the loading position at one end near the loading position, and the pressure head is disposed on the side of the extension toward the support positioning member connected to the connecting sleeve. The pressure head includes a holding portion and a bearing portion extending along the sliding direction of the slide shaft. The holding portion is connected to the extension, and the bearing portion is disposed at one end of the holding portion away from the extension. The bearing portion is configured to bear the first workpiece, and the holding portion is configured to hold the first workpiece.

[0023] The embodiments of this application will be further described below with reference to the accompanying drawings.

[0024] Please see Figure 1 , Figure 2 and Figure 3 This application provides a pressing device 100 for assembling a first workpiece 200 onto a second workpiece 300. The first workpiece 200 can be a small part, and can be a ring-shaped structure or a block-shaped structure with grooves. The second workpiece 300 can be the back cover, middle plate, etc. of an electronic product, such as a mobile phone or tablet. The second workpiece 300 has one or more positions for assembling the first workpiece 200, and the positions where the first workpiece 200 is to be installed can have grooves or other structures. In this embodiment, the position on the second workpiece 300 where the first workpiece 200 is to be installed is located on the side wall of the second workpiece 300. The pressing device 100 includes a positioning mechanism 10 and a pressing mechanism 20.

[0025] Specifically, the positioning mechanism 10 includes a support base 11 and a positioning component 12. The support base 11 is provided with a loading position 111 for carrying the second workpiece 300. The positioning component 12 is arranged around the loading position 111 and is configured to position the second workpiece 300. The support base 11 can be a plate-like structure, and the support base 11 can be connected to a plurality of support legs 14 for supporting the plate-like structure support base 11. The lower ends of the support legs 14 are connected to the base 15. The positioning component 12 is used to abut against the four sides of the second workpiece 300, thereby positioning the second workpiece 300.

[0026] The pressing mechanism 20 includes a pressing assembly 21 and a driving assembly 22. The pressing assembly 21 includes a connecting sleeve 211, a sliding shaft 212, a pressing head 213, and a limiting member 214. The connecting sleeve 211 is detachably connected to the positioning assembly 12. The sliding shaft 212 is slidably connected to the connecting sleeve 211. One end of the sliding shaft 212 near the loading position 111 protrudes from the connecting sleeve 211 and is provided with the limiting member 214. The pressing head 213 is located at the end of the sliding shaft 212 near the loading position 111 and faces the positioning assembly 22. Positioning component 12 is provided, and pressure head 213 is configured to carry first workpiece 200. Drive component 22 is connected to the end of slide shaft 212 away from loading position 111. Drive component 22 is used to drive slide shaft 212 to slide along connecting sleeve 211 so that slide shaft 212 drives pressure head 213 to move toward positioning component 12, thereby assembling first workpiece 200 onto second workpiece 300. Limiting member 214 is configured to abut against connecting sleeve 211 to limit the movement distance of slide shaft 212.

[0027] The connecting sleeve 211 can be a cuboid structure, and the part of the sliding shaft 212 that is slidably connected to the connecting sleeve 211 can also be a cuboid structure. The pressure head 213 can be provided with a structure for supporting the first workpiece 200, such as a protrusion or a groove, to stably support the first workpiece 200. During pressing, the first workpiece 200 is first installed on the pressure head 213, and then the connecting sleeve 211 is installed on the positioning assembly 12, so that the positions of the pressure head 213 and the first workpiece 200 correspond to the positions of the first workpiece 200 to be installed on the second workpiece 300. The sliding shaft 212 is driven to slide along the connecting sleeve 211 by the driving assembly 22. The sliding shaft 212 drives the pressure head 213 and the first workpiece 200 to move toward the second workpiece 300 until the limiting member 214 abuts against the connecting sleeve 211, completing the pressing assembly. Then, the sliding shaft 212 is driven to move in the opposite direction by the driving assembly 22 so that the pressure head 213 is disengaged from the first workpiece 200, and the pressing assembly 21 can be disassembled. If it is necessary to press and assemble the first workpiece 200 at other positions of the second workpiece 300, then install the first workpiece 200 on the press head 213 again, and install the connecting sleeve 211 at other positions of the positioning assembly 12, so that the press head 213 and the first workpiece 200 correspond to the positions of other first workpieces 200 to be installed on the second workpiece 300.

[0028] The pressing device 100 provided in this application embodiment can position the second workpiece 300 through the cooperation of the support base 11 and the positioning component 12 of the positioning mechanism 10, thereby improving the pressing stability and accuracy. The pressing component 21 in the pressing mechanism 20 can be installed on the positioning component 12, and the connecting sleeve 211 in the pressing component 21 can be detachably connected to the positioning component 12, serving to connect and adjust the position. When multiple first workpieces 200 need to be pressed on the second workpiece 300, the position of the connecting sleeve 211 connected to the positioning component 12 can be adjusted so that the sliding shaft 212 and the pressing head 213 correspond to the position of the first workpiece 200 to be installed on the second workpiece 300. The pressure head 213 is used to support the first workpiece 200. The drive assembly 22 can drive the slide shaft 212 to slide along the connecting sleeve 211, thereby moving the pressure head 213 and the first workpiece 200 toward the position where the first workpiece 200 is to be installed on the second workpiece 300, until the pressure head 213 presses the first workpiece 200 onto the second workpiece 300. By accurately corresponding the pressing position, the pressing accuracy can be improved. During pressing, the limiting member 214 connected to the slide shaft 212 abuts against the connecting sleeve 211, thereby limiting the movement distance of the slide shaft 212, thus limiting the degree to which the pressure head 213 presses the first workpiece 200, avoiding incomplete pressing or over-pressing, and further ensuring the pressing accuracy.

[0029] In some embodiments, see Figure 3 and Figure 4 The sliding shaft 212 has a receiving hole 2121 at one end near the loading position 111. The limiting member 214 includes a plug-in end 2141 and a limiting end 2142 arranged opposite to each other. The plug-in end 2141 is configured to be inserted into the receiving hole 2121, and the limiting end 2142 is located outside the receiving hole 2121. The receiving hole 2121 is a regular polygonal hole. The cross-section of the plug-in end 2141 of the limiting member 214 is a regular polygon that matches the receiving hole 2121. The cross-section of the limiting end 2142 of the limiting member 214 is a polygon that corresponds to the plug-in end 2141. The cross-sectional area of ​​the limiting end 2142 is larger than the cross-sectional area of ​​the plug-in end 2141. Each side of the limiting end 2142 corresponds one-to-one with each side of the plug-in end 2141. The distance between each side of the limiting end 2142 and its corresponding side of the plug-in end 2141 is different. The longitudinal section of the limiting member 214 is approximately T-shaped. The insertion end 2141 can be movably inserted into the receiving hole 2121, and the limiting end 2142 is disposed outside the receiving hole 2121 to abut against the connecting sleeve 211. The receiving hole 2121 can be a regular triangular hole, a regular quadrilateral hole, a regular pentagonal hole, etc. The cross section of the insertion end 2141 can be an equilateral triangle, a square, a regular pentagon, etc., corresponding to the receiving hole 2121, and the cross section of the limiting end 2142 can be a triangle, a quadrilateral, a pentagon, etc., corresponding to the insertion end 214.

[0030] For ease of understanding, this embodiment uses an example where the receiving hole 2121 is a regular quadrilateral, the cross-section of the insertion end 2141 is a square, and the cross-section of the limiting end 2142 is a quadrilateral. By setting the receiving hole 2121 as a regular quadrilateral and the cross-section of the insertion end 2141 as a square that matches the receiving hole 2121, the insertion end 2141 can be positioned and limited, increasing the stability of the insertion end 2141 after insertion into the receiving hole 2121 and preventing the insertion end 2141 from rotating. The cross-sectional area of ​​the limiting end 2142 is larger than that of the insertion end 2141, allowing each side of the limiting end 2142 to protrude beyond the side of its corresponding insertion end 2141. Furthermore, the distance between each side of the limiting end 2142 and the side of its corresponding insertion end 2141 is not the same. Please refer to the reference document. Figure 4 The numbers a, b, c, and d in the equation, where a < b < c < d, allow the sliding shaft 212 to move at different distances when different sides of the limiting end 2142 are opposite to the connecting sleeve 211. This results in different distances that the pressure head 213 presses against the first workpiece 200. Consequently, the position of the limiting element 214 can be adjusted to meet different pressing requirements, thus adjusting the pressing distance of the first workpiece 200 at different and / or the same position. In this embodiment, the distance between the side of the limiting end 2142 and the corresponding side of the insertion end 2141 can be 0.10cm, 0.15cm, 0.20cm, and 0.25cm. Of course, other dimensions are also possible and can be set according to actual needs; no limitation is made here. The difference in distance between the side of each limiting end 2142 and the corresponding side of the insertion end 2141 can be arranged in an arithmetic sequence, facilitating adjustment by operators and providing strong versatility. Alternatively, it can be set according to specific needs, i.e., setting dedicated sides for different requirements to provide a stop, thus enhancing specialization.

[0031] In some embodiments, see Figure 1 , Figure 2 and Figure 3The positioning assembly 12 includes two support positioning members 121, both disposed on the support base 11. The two support positioning members 121 are spaced apart on both sides of the loading position 111. The two support positioning members 121 cooperate to position the second workpiece 300. Each support positioning member 121 has a positioning groove 1211 spaced apart along the sliding direction of the sliding shaft 212 on the side opposite to the support base 11. The outer wall of the connecting sleeve 211 is provided with a positioning protrusion 2111 adapted to the positioning groove 1211. The positioning protrusion 2111 is configured to be inserted into the positioning groove 1211 to position the connecting sleeve 211. The support positioning member 121 can be a cuboid structure. By providing two support positioning members 121, the second workpiece 300 can be positioned. The positioning groove 1211 can be a cuboid groove. The number of positioning grooves 1211 on the supporting positioning member 121 can be two, three, four, etc. The number and position of the positioning grooves 1211 on each supporting positioning member 121 can be set according to the number and position of the first workpiece 200 to be installed on the second workpiece 300, and are not limited here. The structure of the positioning protrusion 2111 is adapted to the structure of the positioning groove 1211, which can increase the stability of the connecting sleeve 211 when the positioning protrusion 2111 is inserted into the positioning groove 1211.

[0032] In some embodiments, see Figure 3 The connecting sleeve 211 has a rectangular hole 2112 extending along the sliding direction of the sliding shaft 212. The longitudinal section of the sliding shaft 212 is a rectangle that matches the rectangular hole 2112, and the sliding shaft 212 is slidably positioned within the rectangular hole 2112. This allows the sliding shaft 212 to slide smoothly within the rectangular hole 2112 while restricting its degrees of freedom in other directions. This precise guiding design ensures that the movement trajectory of the sliding shaft 212 remains consistent, preventing offset or rotation during sliding, thereby improving the accuracy and stability of the pressing process.

[0033] In some embodiments, see Figure 1 and Figure 3 The drive assembly 22 includes a flange 221 and a drive handle 222. The flange 221 is threadedly connected to the end of the sliding shaft 212 away from the loading position 111. The drive handle 222 is connected to the flange 221 and is used to drive the flange 221 to rotate, thereby driving the sliding shaft 212 to slide. The sliding shaft 212 drives the pressure head 213 to move towards the positioning assembly 12, thereby assembling the first workpiece 200 onto the second workpiece 300. The drive handle 222 can be a rod-shaped structure. For ease of operation, multiple drive handles 222 can be connected to the flange 221, such as two, three, or four. In use, the operator drives the flange 221 to rotate through the drive handle 222, thereby driving the sliding shaft 212 to move along the connecting sleeve 211 under the action of the threaded connection.

[0034] It is understood that in other embodiments, the drive component 22 may also be other drive structures, such as an electric telescopic mechanism, which can drive the sliding shaft 212 to slide.

[0035] In some embodiments, see Figure 1 and Figure 3 The sliding shaft 212 has an extension 2122 extending toward the loading position 111 at one end near the loading position 111. A pressure head 213 is located on the side of the extension 2122 facing the support positioning member 121 connected to the connecting sleeve 211. The pressure head 213 includes a holding portion 2131 and a supporting portion 2132 extending along the sliding direction of the sliding shaft 212. The holding portion 2131 is connected to the extension 2122, and the supporting portion 2132 is located at the end of the holding portion 2131 opposite to the extension 2122. The supporting portion 2132 is configured to support the first workpiece 200, and the holding portion 2131 is configured to hold the first workpiece 200. By providing the extension 2122 and mounting the pressure head 213 on it, the pressure head 213 can get closer to the second workpiece 300, ensuring the accuracy of the pressing position. The holding part 2131 and the bearing part 2132 of the pressure head 213 perform different functions. The holding part 2131 is used to press the first workpiece 200, while the bearing part 2132 is used to support the first workpiece 200. This can improve the positional accuracy of the pressure head 213 in bearing the first workpiece 200 and also ensure the pressing effect.

[0036] In some embodiments, see Figure 1 and Figure 2 The positioning component 12 also includes a positioning block 122 and a positioning pin 123. The positioning block 122 and the positioning pin 123 are spaced apart on both sides of the loading position 111. The positioning block 122 cooperates with the positioning pin 123 to position the second workpiece 300. The positioning mechanism 10 also includes a pressing component 13, which includes a pressure plate 131. The pressure plate 131 is rotatably connected to the positioning block 122 and is configured to press the second workpiece 300 to position it. Through the cooperation of the positioning block 122 and the positioning pin 123, the second workpiece 300 can be positioned. With the further cooperation of the two supporting positioning members 121, the second workpiece 300 can be precisely constrained on the horizontal plane. By setting the pressure plate 131, the second workpiece 300 can be rotated and pressed, thereby positioning the second workpiece 300 and ensuring that the second workpiece 300 maintains a stable position during the pressing process, thus improving the pressing accuracy and pressing quality.

[0037] In some embodiments, see Figure 1 and Figure 2The pressing assembly 13 also includes a flexible pressing block 132, which is connected to the pressing plate 131. The flexible pressing block 132 is configured to abut against the second workpiece 300 to flexibly press the second workpiece 300. The flexible pressing block 132 can be made of materials such as urethane. By setting the flexible pressing block 132, damage to the second workpiece 300 during the pressing process can be effectively reduced, which is especially suitable for second workpieces 300 with high surface requirements. This flexible pressing method can avoid scratches, deformation or other damage caused by hard contact, thereby significantly improving the product yield.

[0038] It is understandable that when the pressure plate 131 and the flexible pressure block 132 are pressing the second workpiece 300, they can both avoid the sliding shaft 212, pressure head 213 and limiting member 214 of the pressing mechanism 20 by setting avoidance positions and / or avoidance grooves, so as to avoid affecting the pressing mechanism 20 to perform pressing operations.

[0039] In some embodiments, the pressing assembly 13 further includes a latch 133, which is disposed on the support base 11 and near the material loading position 111 on the side away from the positioning block 122. The latch 133 is configured to hold the end of the pressure plate 131 away from the positioning block 122 to fix the pressure plate 131. By providing the latch, the pressure plate 131 can be firmly fixed when pressing the second workpiece 300, preventing the pressure plate 131 from loosening or shifting due to external forces (such as reaction forces during the pressing process), thereby ensuring the stability of the pressing process.

[0040] In some embodiments, see Figure 1 and Figure 2 The pressing assembly 13 also includes multiple support columns 134, which are all disposed on the support base 11 and close to the buckle 133. The multiple support columns 134 are configured to support the pressure plate 131 when it presses the second workpiece 300. By providing the support columns 134, the pressure plate 131 can be supported, preventing it from directly pressing against the connecting sleeve 211 of the pressing mechanism 20, which could lead to instability in the pressure plate 131's holding of the second workpiece 300 or affect the pressing mechanism 20's pressing of the first workpiece 200.

[0041] The working process of the pressing device 100 provided in this application embodiment is roughly as follows: First, the second workpiece 300 is placed in the loading position 111 of the support base 11, and positioned on the horizontal plane by the two supporting positioning members 121, the positioning block 122, and the positioning pin 123 of the positioning assembly 12. Then, the first workpiece 200 is installed on the pressure head 213 of the pressing mechanism 20. The first workpiece 200 is installed on the bearing part 2132 of the pressure head 213 and abuts against the holding part 2131. Next, the connecting sleeve 211 of the pressing mechanism 20 is installed on the supporting positioning member 121. During installation, the positioning protrusion 2111 of the connecting sleeve 211 is inserted into the positioning groove 1211 of the supporting positioning member 121, and the extension part 2122 of the sliding shaft 212 is positioned above the second workpiece 300. After the pressing mechanism 20 is installed, rotate the pressing plate 131 so that the flexible pressing block 132 presses the second workpiece 300. The support column 134 supports the end of the pressing plate 131 away from the positioning block 122, and then the pressing plate 131 is held by the buckle 133.

[0042] Then, rotate the drive handle 222 to rotate the flange 221. The flange 221 drives the sliding shaft 212 to move, which in turn moves the pressure head 213 and the first workpiece 200 toward the second workpiece 300 until the limiting end 2142 of the limiting member 214 abuts against the connecting sleeve 211. At this point, the first workpiece 200 is assembled in place. Then, rotate the drive handle 222 in the opposite direction to make the flange 221 drive the sliding shaft 212 to move in the opposite direction until the pressure head 213 separates from the first workpiece 200.
