Description

Technical Field

[0001] This application relates to the field of product positioning and assembly technology, and in particular to positioning and pressure holding devices. Background Technology

[0002] With the development of technology in the fields of 3C electronic products and medical products, the requirements for product assembly precision are becoming increasingly stringent.

[0003] Among related technologies, the most commonly used method is single-sided product positioning, which mainly relies on one edge of the product as a positioning reference. The product is fixed in the reference position by a corresponding positioning structure, thereby completing the positioning operation of the product during the assembly process.

[0004] However, in the aforementioned single-sided positioning method, due to the inconsistency in tolerances of the product itself, single-sided positioning only uses one edge as a reference, which can easily lead to inaccurate positioning. This affects the docking accuracy of the product during the assembly process, and may result in uneven gaps, misaligned parts, and other problems in the assembled product, thus affecting the assembly accuracy and yield of the product. Utility Model Content

[0052] See Figure 1 , Figure 2 , Figure 3 As shown, Figure 1 A schematic diagram of the positioning and pressure-holding device according to an embodiment of this application is shown. Figure 2 A top view schematic diagram of a positioning and pressure-holding device according to an embodiment of this application is shown. Figure 3 A schematic diagram of the positioning component 20 in one embodiment of this application is shown.

[0053] An embodiment of this application provides a positioning and pressure-holding device, including a base 10, a positioning component 20, and a pressure-holding component 30, for positioning and pressure-holding operations on electronic devices, electronic components, and other products 11.

[0054] In this embodiment, the positioning component 20 is disposed on the base 10. The positioning component 20 includes a support part 21, a moving part 22, a driving part 23, and a plurality of fixing units 24. The plurality of fixing units 24 are disposed opposite to each other on the base 10 along a first length direction, and the plurality of fixing units 24 form a receiving space, which is configured to place and fix the product 11.

[0055] The movable part 22 is movably disposed on the base 10 along the second length direction and located within the receiving space; the movable part abuts against multiple fixed units. The drive part 23 is rotatably connected to the movable part 22, and the drive part 23 is configured to pull the movable part 22 along the second length direction when rotated, so as to drive the multiple fixed units 24 to move relative to the product 11.

[0056] The pressure holding assembly 30 is rotatably disposed above the positioning assembly 20, and the pressure holding assembly 30 is configured to apply pressure to the product 11.

[0057] In this embodiment, the base 10 is made of metal and is shaped as a rectangular flat plate, providing support for the installation of the positioning component 20.

[0058] The support part 21 is mounted on the base 10 and has a cuboid structure. The support part 21 is made of metal and is hollow inside to provide space for the movement of the movable part 22.

[0059] like Figure 2 As shown, i1 represents the first length direction. Multiple fixing units 24 are arranged opposite each other on the base 10 along the first length direction, i.e., along the width direction of the support portion 21. In this embodiment, the positioning component 20 includes four fixing units 24, wherein every two fixing units 24 are respectively arranged opposite each other on both sides of the support portion 21 in the width direction, forming an accommodating space with the surface of the support portion 21.

[0060] like Figure 2 As mentioned above, i2 is the second length direction. The movable part 22 is movably disposed on the base 10 and located within the receiving space along the second length direction, that is, along the length direction of the support part 21. The movable part 22 abuts against the plurality of fixed units 24 respectively, and the plurality of fixed units 24 are moved by the movement of the movable part 22.

[0061] Furthermore, the movable part 22 includes a centering plate 221, which is movably disposed inside the support part 21. The centering plate 221 can move along the length direction of the support part 21 and is used to abut against the fixed unit 24.

[0062] Furthermore, the centering plate 221 has protruding arc-shaped surfaces 2211 on both sides, and each fixing unit 24 has an annular surface 241 that abuts against the arc-shaped surface 2211 at one end near the centering plate 221. The centering plate 221 moves along the second length direction to press the annular surface of the fixing unit 24, causing the fixing unit 24 to move outward to increase the accommodating space and facilitate the placement of the product 11.

[0063] Furthermore, the end of the fixing unit 24 that contacts the product 11 is configured with an L-shaped structure for snapping onto the side of the product 11, thereby improving the stability of the fixation. A rubber pad is affixed to the surface of the fixing unit 24 that contacts the product 11 to prevent scratching the surface of the product 11 during the positioning process.

[0064] The drive unit 23 is rotatably connected to the moving unit 22, and the drive unit 23 is rotatably mounted. By rotating the drive unit 23, the moving unit 22 is driven to move along the length direction of the support unit 21, thereby driving the four fixed units to move relative to the product 11 along the width direction of the support unit 21.

[0065] Furthermore, the drive unit 23 is a handle 231, and the end of the handle 231 that contacts the moving part 22 has a convex surface. By utilizing the cooperation between the convex surface and the side of the moving part 22, the drive unit 23 is rotated, thereby driving the centering plate 221 to move linearly. When the drive unit 23 rotates in a clockwise or counterclockwise direction, it pulls the centering plate 221 to move along the length direction of the support part 21.

[0066] The pressure holding assembly 30 is rotatably disposed above the positioning assembly 20. The pressure holding assembly 30 includes a pressure plate 31, which is made of metal and has a rectangular structure. The pressure plate 31 is used to cover the surface of the product 11 and apply pressure to the product 11 to maintain pressure, thereby improving the packaging stability of the product 11.

[0067] In the specific implementation process, when the drive unit 23 rotates in a clockwise or counterclockwise direction, it pulls the centering plate 221 to move along the length direction of the support unit 21. The arc-shaped surfaces 2211 on both sides of the centering plate 221 press against the annular surface 241 of the fixing unit 24, thereby pushing the four fixing units 24 to move outward to open the space between them, so as to facilitate the placement of the product 11 for positioning and fixing.

[0068] The product 11 is placed on the support 21, and the drive unit 23 rotates in a counterclockwise or clockwise direction, causing the centering plate 221 to move in the opposite direction. The arc-shaped surfaces 2211 on both sides of the centering plate 221 separate from the annular surface 241 of the fixing unit 24, so that the fixing unit 24 can be reset to the initial position to clamp the two sides of the product 11 and realize the positioning process of the product 11.

[0069] The pressure plate 31 of the pressure holding assembly 30 is placed on the surface of the product 11 to apply pressure to the product 11, thereby achieving the pressure holding process of the product 11.

[0070] In summary, the aforementioned positioning and pressure-holding device arranges multiple fixing units 24 along the first length direction on the base 10 to form a receiving space. A moving part 22 is arranged along the second length direction on the base 10 and located within the receiving space, abutting against the multiple fixing units 24. A driving part 23 is rotatably connected to the moving part 22. When the driving part 23 rotates, it drives the moving part 22 to move along the second length direction, thereby moving the multiple fixing units 24 along the first length direction to increase the receiving space and facilitate the placement of the product 11. The driving part 23 rotates in the opposite direction, resetting the moving part 22 and the fixing units 24, allowing the multiple fixing units 24 to abut against the product 11, thus fixing the product 11 and improving positioning stability. Furthermore, the pressure-holding assembly 30 applies pressure to the product 11, facilitating operations such as packaging and improving the production quality of the product 11.

[0071] Combination Figure 5 , Figure 6 As shown, Figure 5 This is a side view of the moving part 22 and the driving part 23 provided in one embodiment of this application. Figure 6 This is a schematic diagram of the structure of the fixing unit 24 provided in one embodiment of this application.

[0072] In some embodiments, the fixing unit 24 includes a mounting block 242, a roller 243, a connecting block 244, a first positioning block 245, and a first linear guide 246, the first linear guide 246 being arranged along a first length direction; the bottom of the connecting block 244 is provided with a first slider, the first slider being slidably connected to the first linear guide 246; one end of the mounting block 242 near the moving part 22 is connected to the roller 243, and the other end is connected to the connecting block 244; the first positioning block 245 is disposed on the connecting block 244, and the first positioning block 245 is configured to press against the product 11.

[0073] Specifically, the first linear guide 246 is arranged along the first length direction, that is, along the width direction of the support part 21. The first linear guide 246 is a linear guide rail, which provides guidance for the sliding of the adapter block 244.

[0074] The bottom of the adapter block 244 is provided with a first slider, which is slidably connected to the first linear rail 246. The adapter block 244 is slidably mounted on the first linear rail 246 through the first slider at its bottom and slides along the width direction of the support part 21 to drive the overall fixing unit 24 to move and improve its movement stability.

[0075] A roller 243 is connected to one end of the mounting block 242 near the moving part 22. The roller 243 is fixed to the mounting block 242 by a positioning pin. The other end of the mounting block 242 is connected to the adapter block 244. Furthermore, an annular surface 241 is provided on the outer periphery of the roller 243. The annular surface 241 is used to abut against the arc-shaped surface 2211 provided on the side of the centering plate 221 near the roller 243.

[0076] The first positioning block 245 is installed on the adapter block 244. The end of the first positioning block 245 near the centering plate 221 is set with an L-shaped structure, which facilitates the positioning and fixing of the side of the product 11, improves its fixing stability, and facilitates subsequent processing and other operations.

[0077] When the centering plate 221 of the moving part 22 moves in a straight line, the arc-shaped surfaces 2211 on both sides of the centering plate 221 press against the annular surface 241 of the roller 243, pushing the roller 243 to move the adapter block 244 and the first positioning block 245 outward, thereby increasing the distance between the two fixed units 24 to facilitate the placement of the product 11. When the centering plate 221 moves in the opposite direction, the arc-shaped surfaces 2211 on both sides of the centering plate 221 separate from the annular surface 241, that is, the roller 243 is no longer under force, causing the adapter block 244 and the first positioning block 245 to reset, thereby clamping the side of the product 11 and realizing the positioning process of the product 11.

[0078] Combination Figure 4 As shown, Figure 4 This is a schematic diagram of the structure of the moving part 22 and the driving part 23 provided in one embodiment of this application.

[0079] In some embodiments, the centering plate 221 is provided with at least one protrusion 2212 on each side along the second length direction, and one side of the protrusion 2212 is provided with an arcuate surface 2211 extending toward the outer edge of the centering plate 221; the arcuate surface 2211 contacts and slides relative to the annular surface 241 of the outer periphery of the roller 243; one end of the protrusion 2212 is configured to abut against the annular surface 241 and limit the movement of the roller 243 along the second length direction.

[0080] Specifically, the centering plate 221 has at least one protrusion 2212 on each of its two long sides along the length of the support portion 21. In this embodiment, the centering plate 221 includes four protrusions 2212, that is, two protrusions 2212 are provided on each of the two long sides of the centering plate 221. One side of each protrusion 2212 has an arcuate surface 2211 extending towards the outer edge of the centering plate 221. This arcuate surface 2211 is used to abut against the annular surface 241 on the outer periphery of the roller 243, and slides relative to the annular surface 241 when the centering plate 221 moves, thereby squeezing the annular surface 241 and pushing the roller 243 outward.

[0081] Furthermore, after the protrusion 2212 slides a certain distance relative to the roller 243, the roller 243 reaches its maximum movement distance. The end of the protrusion 2212 away from the centering plate 221, that is, the extended end of the protrusion 2212, is used to abut against the annular surface 241 of the roller 243, limiting the movement of the roller 243 along the second length direction, keeping the roller 243 stationary, which facilitates the placement of the product 11 between the fixed units 24.

[0082] In one embodiment, the moving part 22 includes a second linear guide 223 and a second slider disposed at the bottom of the centering plate 221. The second linear guide 223 is disposed along a second length direction, and the second slider is slidably connected to the second linear guide 223.

[0083] Specifically, the second linear guide 223 is arranged along the length of the support 21. The second linear guide 223 is a linear guide rail that provides guidance.

[0084] The centering plate 221 is a rectangular plate, and a second slider is provided at the bottom of the centering plate 221. The second slider is slidably connected to the second linear rail 223. The centering plate 221 is slidably mounted on the second linear rail 223 by the second sliding block at the bottom, and moves along the length of the second linear rail 223 to drive the fixed unit 24 to move.

[0085] In one embodiment, the moving part 22 further includes a stop 224, a second positioning block 225, and a limiting plate 226. The stop 224 is slidably disposed on the second linear guide 223, the second positioning block 225 is mounted on the stop 224, and the second positioning block 225 is configured to limit the movement of the product 11 along the second length direction. The limiting plate 226 is disposed between the stop 224 and the driving part 23. One end of the centering plate 221 passes through the stop 224 and the limiting plate 226 and is rotatably connected to the driving part 23.

[0086] Specifically, the stop 224 is slidably mounted on the second linear guide 223. Under the pushing action of the centering plate 221, the stop 224 can move along the extension direction of the second linear guide 223. The second positioning block 225 is mounted on the stop 224 and is used to position and fix the side of the product 11 in the length direction, restricting the movement of the product 11 in the second length direction and ensuring stability.

[0087] The limiting plate 226 is disposed between the stop block 224 and the drive unit 23, which limits the movement range of the centering plate 221 and prevents the centering plate 221 from moving excessively. One end of the centering plate 221 passes through the stop block 224 and the limiting plate 226 and is rotatably connected to the drive unit 23. By rotating the drive unit 23, the centering plate 221 is driven to move along the second length direction.

[0088] In one embodiment, the moving part 22 further includes a second spring 227, one end of which is connected to the limiting plate 226 and the other end is connected to the stop block 224.

[0089] Specifically, one end of the second spring 227 abuts against the limiting plate 226, and the other end of the second spring 227 is connected to the stop block 224. When the drive unit 23 rotates and drives the centering plate 221 to move, the second spring 227 is compressed, which plays a buffering role and makes the centering plate 221 move more smoothly. When the drive unit 23 rotates in the opposite direction to return to the initial position, the second spring 227 resets, and the elastic force of the second spring 227 pushes the centering plate 221 back to the initial position, thereby driving the fixing unit 24 to reset and clamp and position the side of the product 11.

[0090] In one embodiment, the drive unit 23 includes a handle 231, one end of which is provided with a cam 232. The cam 232 abuts against the outer side of the limiting plate 226, and one end of the centering plate 221 is embedded in the cam 232 and rotatably connected to the cam 232.

[0091] Specifically, the drive unit 23 includes a handle 231 and a cam 232. The handle 231 is a long rod made of engineering plastic for easy gripping by the operator. A cam 232, made of metal, is located at one end of the handle 231. The convex surface of the cam 232 abuts against the outer surface of the limiting plate 226, and one end of the centering plate 221 is embedded in and rotatably connected to the cam 232. When the handle 231 is rotated, the cam 232 rotates clockwise or counterclockwise. Since the limiting plate 226 remains stationary, this pulls the centering plate 221 to move linearly.

[0092] In one embodiment, the fixing unit 24 further includes a baffle 247 and a first spring 248, one end of the first spring 248 abutting against the baffle 247 and the other end connected to the adapter block 244.

[0093] Specifically, baffle 247 is fixedly installed on support 21. Baffle 247 is located on the side of adapter block 244 away from centering plate 221, providing support for first spring 248.

[0094] One end of the first spring 248 abuts against the baffle 247, and the other end of the first spring 248 is connected to the adapter block 244. When the centering plate 221 pushes the mounting block 242 and the adapter block 244 to move, the first spring 248 is compressed, which plays a buffering role. And when the centering plate 221 moves in the opposite direction, the elastic force of the spring is used to drive the adapter block 244 and the mounting block 242 to reset, thereby achieving the positioning of the product 11.

[0095] In one embodiment, the support portion 21 includes an upper support plate 211 and a lower support plate 212. The upper support plate 211 is used to place the product 11. The lower support plate 212 has pin holes on two sides along the second length direction. A baffle 247 is disposed at one end of the adapter block 244 away from the centering plate 221. The bottom of the baffle 247 is provided with a pin 2471 that engages with the pin holes.

[0096] Specifically, the upper support plate 211 is rectangular in shape, and the upper support plate 211 is connected to the lower support plate 212 by a snap-fit. The upper support plate 211 is used to place the product 11 and provide support for positioning the product 11. The lower support plate 212 has multiple pin holes evenly distributed on its two sides along the second length direction, that is, on its two long sides.

[0097] The bottom of the baffle 247 is provided with a pin 2471 that engages with the pin hole of the lower support plate 212. The diameter of the pin 2471 matches the pin hole. By inserting the pin 2471 into the pin hole, the baffle 247 and the lower support plate 212 are positioned and fixedly connected, thereby ensuring the stability of the fixed unit 24 during movement.

[0098] Combination Figure 7 As shown, Figure 7 This is a schematic diagram of the structure of the pressure holding assembly 30 provided in one embodiment of this application. In some embodiments, the pressure holding assembly 30 includes a pressure plate 31, a first fixing block 32 and a second fixing block 33, the first fixing block 32 and the second fixing block 33 are respectively disposed on both sides of the moving part 22 along the second length direction; one end of the pressure plate 31 is rotatably connected to the first fixing block 32 through a rotating shaft, and the other end is provided with a hook 34.

[0099] One end of the hook 34 is rotatably connected to the pressure plate 31 via a rotating shaft, and the hook 34 is configured to engage with the latch 331 at the top of the second fixing block 33.

[0100] Specifically, the pressure plate 31 can be made of engineering plastic material and is set as a rectangular structure to provide uniform pressure during the pressure holding process.

[0101] The first fixing block 32 and the second fixing block 33 are respectively fixed on both sides of the support part 21. One end of the pressure plate 31 is rotatably connected to the first fixing block 32 through a rotating shaft, and the other end of the pressure plate 31 is provided with a hook 34, which is used to engage with the latch 331 provided at the top of the second fixing block 33 to fix the pressure plate 31. When it is necessary to apply pressure to the product 11, the product 11 is positioned on the support part 21, and the pressure plate 31 is rotated to engage with the second fixing block 33. The pressure plate 31 contacts the surface of the product 11, thereby applying pressure to the product 11.

[0102] Combination Figure 8 As shown, Figure 8 This is a cross-sectional schematic diagram of the first pressure-holding unit 35 provided in one embodiment of this application.

[0103] In some embodiments, the system further includes a first pressure holding unit 35 and a second pressure holding unit 36. The first pressure holding unit 35 includes a pressure holding head 351, a first pressure block 352, and a third spring 353. The first pressure block 352 is disposed on the pressure plate 31. One end of the pressure holding head 351 passes through the pressure plate 31 and is embedded in the first pressure block 352, while the other end is used to abut against the product 11. One end of the third spring 353 is connected to the first pressure block 352, and the other end is connected to the end of the pressure holding head 351 near the first pressure block 352.

[0104] Specifically, the pressure holding head 351 can be made of silicone. The pressure holding head 351 can provide uniform pressure when it comes into contact with the product 11, while avoiding damage to the surface of the product 11. The part of the pressure holding head 351 that contacts the surface of the product 11 is square or round. One end of the pressure holding head 351 passes through the pressure plate 31 and is embedded in the first pressure block 352, while the other end of the pressure holding head 351 is used to abut against the surface of the product 11.

[0105] The first pressure block 352 is fixed to the pressure plate 31 by bolts. The interior of the first pressure block 352 is provided with a cavity to accommodate the third spring 353 and the pressure holding head 351.

[0106] One end of the third spring 353 abuts against the bottom of the cavity inside the first pressure block 352, and the other end of the third spring 353 abuts against the end of the pressure holding head 351 near the first pressure block 352, so that the pressure holding head 351 can elastically extend and retract within a certain range. The third spring 353 can provide stable elastic force during the pressure holding process, and while applying pressure to the surface of the product 11, it avoids the pressure holding head 351 from making hard contact with the product 11 and damaging the product 11.

[0107] In one embodiment, the second pressure holding unit 36 ​​includes a second pressure block 361, one end of which is engaged with the pressure plate 31, and the other end is used to abut against the product 11.

[0108] Specifically, the second pressure block 361 is made of the same silicone material as the pressure holding head 351. The portion of the second pressure block 361 that contacts the surface of the product 11 is rectangular, increasing the contact area and improving the pressure holding effect. One end of the second pressure block 361 is engaged with the slot of the pressure plate 31, and the other end of the second pressure block 361 is used to abut against the surface of the product 11, achieving uniform pressure on the surface of the product 11. The engagement of the second pressure block 361 with the pressure plate 31 allows the second pressure block 361 to be installed and removed, thereby facilitating maintenance and replacement.

[0109] In one embodiment, the hook 34 includes an engaging portion and a bent portion. The engaging portion engages with the latch to secure the pressure plate. The bent portion extends into the slot of the second fixing block, with a movable gap between it and the top surface of the slot, allowing the hook 34 to move within a certain range, thereby unlocking the connection between the engaging portion and the latch.

[0110] A fourth spring is provided between the slot and the bend. One end of the fourth spring is fixed to the top surface of the slot, and the other end is fixed to the bottom surface of the bend. When the hook 34 moves to unlock, it compresses the fourth spring. After the hook 34 unlocks, the fourth spring returns to its original position, providing elastic force to reset the hook 34.

[0111] In one embodiment, a buffer 37 is also included, which is disposed on the base 10 and located between the first fixing block 32 and the second fixing block 33, and the top of the buffer 37 has a preset gap with the pressure plate 31.

[0112] Specifically, the buffer 37 is mounted on the base 10 and located between the first fixing block 32 and the second fixing block 33. A preset gap exists between the top of the buffer 37 and the pressure plate 31, providing a buffering distance to achieve the desired protective effect on the product 11. When the pressure plate 31 is pressed down, the buffer 37 can buffer the product 11 when the pressure plate 31 approaches the second fixing block 33 and when the pressure plate 31 applies pressure to the product 11, thus protecting the product 11.

[0113] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
