Description

Technical Field

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

[0002] In industrial production, it is often necessary to press two workpieces together. Currently, the common method is to assemble the two workpieces using an assembly fixture, then position the assembly fixture under the pressing equipment using a positioning fixture, and finally, the pressing equipment completes the pressing operation. However, this process is cumbersome, labor-intensive, and has a low degree of automation. Although there are solutions that use drive mechanisms to automatically move the assembly fixture and positioning fixture under the pressing equipment, this method requires multiple power sources, resulting in high production costs. Utility Model Content

[0003] In view of the above, it is necessary to propose a pressing device that can move the workpiece to the pressing assembly and complete the pressing with a single power source, so as to achieve simple operation, high degree of automation and low production cost.

A linkage rod has a linkage part and a driving part arranged opposite to each other, the extension directions of the linkage part and the driving part intersect, the linkage part is slidably connected to the positioning component, and the driving part is disposed toward the pushing member; wherein, the pressing driving member drives the pressing head and the pushing member to move closer to the base, so that the pushing member pushes the driving part to rotate toward the base, thereby driving the linkage part to move, the linkage part pulls the positioning component to move toward the underside of the pressing head, and the pressing head presses the first workpiece and the second workpiece on the positioning component.

[0005] The aforementioned pressing device, through a positioning component, can position the first and second workpieces. The pressing component includes a pressing drive, a pressing head, and a pushing component. When the pressing drive drives the pressing head and the pushing component to move towards the base of the support component, the pushing component pushes the driving part of the linkage rod of the linkage component to rotate, thereby causing the linkage part of the linkage rod to rotate. The linkage part pulls the positioning component to move below the pressing head, and the pressing head, driven by the pressing drive, presses the first and second workpieces together. This pressing device, through a single power source, can drive the pressing head, the pushing component, the linkage rod, and the positioning component. Furthermore, during the movement of the pressing head, the linkage rod moves the positioning component below the pressing head, enabling the pressing head to press the first and second workpieces together. This achieves simple operation, high automation, and eliminates the need for additional power sources, effectively reducing production costs.

The rotating shaft is rotatably connected to the base, the linkage rod is connected to the rotating shaft, the snap-fit ​​member is connected to the linkage part, and the reset elastic member is sleeved on the rotating shaft. The reset elastic member has two opposing first straight arms and second straight arms. The first straight arm abuts against the base and is located on the side of the rotating shaft away from the positioning assembly. The second straight arm abuts against the snap-fit ​​member. The reset elastic member is configured to push the snap-fit ​​member to move, thereby driving the linkage rod to rotate and reset.

[0007] In some embodiments, the snap-fit ​​member has a snap-fit ​​groove, which is configured to accommodate the second straight arm and hold the second straight arm by means of the groove wall.

[0010] In some embodiments, the positioning component further includes a second roller, which is rotatably connected to the sliding pin and slidably disposed in the sliding hole.

[0011] In some embodiments, the positioning assembly includes a sliding frame and a positioning seat, the sliding frame being slidably disposed on the base, and the positioning seat being connected to the side of the sliding frame opposite to the base, the positioning seat being configured to carry and position the first workpiece and the second workpiece.

[0012] In some embodiments, the positioning component further includes a plurality of positioning pins, all of which are disposed on the side of the positioning seat away from the sliding frame, and all of which are configured to pass through the first workpiece to position the first workpiece.

[0013] In some embodiments, the positioning assembly further includes a cover plate having a pressing hole and a plurality of positioning holes. The pressing hole is adapted to the pressing head and is configured to position the second workpiece.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0022] The embodiments of this application will be further described below with reference to the accompanying drawings.

[0023] Please see Figure 1 , Figure 2 and Figure 3 This application provides a pressing device 100 for pressing a first workpiece 200 and a second workpiece 300. Both the first workpiece 200 and the second workpiece 300 can be sheet-like or plate-like structures, and an adhesive or similar substance can be coated between them. In this embodiment, multiple second workpieces 300 can be spaced apart on the first workpiece 200, such as two, three, or four second workpieces 300. The specific number and position of the second workpieces 300 are determined according to actual production needs and are not limited here. The pressing device 100 includes a support assembly 10, a positioning assembly 20, a pressing assembly 30, and a linkage assembly 40.

[0024] Specifically, please see Figure 1 , Figure 2 and Figure 3 The support component 10 includes a base 11 and a support frame 12 disposed on the base 11. The base 11 can be a plate-shaped structure to provide stable support, and the support frame 12 can be a frame structure composed of multiple plate-shaped structures to provide load-bearing function.

[0025] The positioning component 20 is slidably connected to the base 11 and is configured to position the first workpiece 200 and the second workpiece 300. A slide rail may be provided between the positioning component 20 and the base 11 to improve the stability of the movement of the positioning component 20. In this embodiment, the movement direction of the positioning component 20 is towards or away from the support frame 12.

[0026] The pressing assembly 30 includes a pressing drive 31, a pressing head 32, and a pushing member 33. The pressing drive 31 is connected to the support frame 12, the pressing head 32 is connected to the pressing drive 31, and the pushing member 33 is connected to the pressing head 32. The pressing drive 31 is configured to drive the pressing head 32 and the pushing member 33 closer to or further away from the base 11. The pressing drive 31 can be a cylinder, a telescopic motor, etc. The structure of the pressing head 32 is adapted to the structure of the second workpiece 300. In this embodiment, multiple pressing heads 32 can be provided, such as two, three, four, etc. The specific number and position of the pressing heads 32 are adapted to the number and position of the second workpiece 300, and are not limited here. The pushing member 33 is generally a rod-shaped structure. In this embodiment, the end of the pushing member 33 away from the pressing head 32 is set as L-shaped.

[0027] The linkage assembly 40 includes a linkage rod 41 rotatably connected to the base 11. The linkage rod 41 has a linkage portion 411 and a driving portion 412 disposed opposite to each other. The extending directions of the linkage portion 411 and the driving portion 412 intersect. The linkage portion 411 is slidably connected to the positioning assembly 20, and the driving portion 412 is disposed toward the pushing member 33. The linkage rod 41 is generally L-shaped or V-shaped. The middle part of the linkage rod 41 is rotatably connected to the base 11, and both the linkage portion 411 and the driving portion 412 extend in a direction away from the base 11.

[0028] In this configuration, the pressing drive 31 drives the pressing head 32 and the pushing member 33 to move closer to the base 11, causing the pushing member 33 to push the driving part 412 to rotate toward the base 11. This, in turn, drives the linkage part 411 to move. The linkage part 411 pulls the positioning assembly 20 to move downward toward the pressing head 32, and the pressing head 32 presses the first workpiece 200 and the second workpiece 300 on the positioning assembly 20. After pressing is completed, the pressing drive 31 drives the pressing head 32 and the pushing member 33 to move away from the base 11. At this time, the pushing member 33 moves away from the driving part 412 of the linkage rod 41, and the positioning assembly 20 can be manually driven away from the support frame 12, causing the linkage rod 41 to reset. After the positioning assembly 20 moves away from the support frame 12, it is convenient for loading and unloading.

[0029] The pressing device 100 provided in this application embodiment can position the first workpiece 200 and the second workpiece 300 through the positioning component 20. The pressing component 30 includes a pressing drive 31, a pressing head 32, and a pushing member 33. When the pressing drive 31 drives the pressing head 32 and the pushing member 33 to move toward the base 11 of the support component 10, the pushing member 33 pushes the driving part 412 of the linkage rod 41 of the linkage component 40 to rotate, thereby driving the linkage part 411 of the linkage rod 41 to rotate. The linkage part 411 pulls the positioning component 20 to move below the pressing head 32. The pressing head 32 presses the first workpiece 200 and the second workpiece 300 under the drive of the pressing drive 31. The pressing device 100 provided in this application embodiment can drive the pressing head 32, the pushing member 33, the linkage rod 41 and the positioning component 20 to move through a pressing drive member 31 as a power source. Then, during the movement of the pressing head 32, the positioning component 20 is moved to below the pressing head 32 through the linkage rod 41 so that the pressing head 32 presses the first workpiece 200 and the second workpiece 300. This achieves simple operation, high degree of automation, no need for additional power sources, and effectively reduces production costs.

[0030] In some embodiments, see Figure 1 and Figure 2 The linkage assembly 40 also includes a rotating shaft 42, a snap-fit ​​member 43, and a reset elastic member 44. The rotating shaft 42 is rotatably connected to the base 11, the linkage rod 41 is connected to the rotating shaft 42, the snap-fit ​​member 43 is connected to the linkage part 411, and the reset elastic member 44 is sleeved on the rotating shaft 42. The reset elastic member 44 has two opposingly arranged first straight arms 441 and second straight arms 442. The first straight arm 441 abuts against the base 11 and is located on the side of the rotating shaft 42 away from the positioning assembly 20. The second straight arm 442 abuts against the snap-fit ​​member 43. The reset elastic member 44 is configured to push the snap-fit ​​member 43 to move so as to drive the linkage rod 41 to rotate and reset.

[0031] The rotating shaft 42 can be rotatably connected to the base 11 via a structure such as a bearing. The snap-fit ​​component 43 can be a block structure, and the reset elastic component 44 can be a torsion spring, etc. By setting the rotating shaft 42, the rotational stability of the linkage rod 41 can be improved. In this embodiment, one end of the rotating shaft 42 extends out of the linkage rod 41 to support the reset elastic component 44. The reset elastic component 44 abuts against the base 11 and the snap-fit ​​component 43 respectively through its first straight arm 441 and second straight arm 442, providing a stable reset torque for the linkage rod 41 and ensuring that the linkage rod 41 can quickly and accurately return to its initial position after each pressing. Compared with relying on gravity or manual reset, setting the reset elastic component 44 can avoid reset delay or jamming, ensuring the smoothness of continuous operation.

[0032] In some embodiments, see Figure 1 and Figure 2The locking member 43 has a locking groove 431, which is configured to accommodate the second straight arm 442 and hold it in place via the groove wall. The locking groove 431 can be a U-shaped groove or a V-shaped groove. The locking groove 431 securely restricts the second straight arm 442 within the locking member 43, preventing the reset elastic member 44 from loosening or shifting due to vibration or impact during frequent operation, thus ensuring the continuous and stable transmission of the reset force. The locking groove 431 provides a clear positioning reference for the second straight arm 442. During assembly, the straight arm only needs to be inserted into the locking groove 431, eliminating the need for repeated position adjustments and reducing human error during installation.

[0033] In some embodiments, see Figure 1 and Figure 2 The linkage assembly 40 also includes a first roller 45, which is rotatably connected to the drive unit 412 and configured to abut against the push member 33. The first roller 45 can be a bearing structure. By setting the first roller 45, the sliding friction between the drive unit 412 and the push member 33 is converted into rolling friction. The coefficient of friction of rolling friction is much smaller than that of sliding friction, which can significantly reduce energy loss and improve motion efficiency. Rolling friction causes less wear on mechanical parts. Compared with sliding friction, the design of the first roller 45 can reduce the wear of the drive unit 412 and the push member 33, thereby extending the service life of the components. The rolling contact method of the first roller 45 can reduce motion jamming or shaking caused by uneven surfaces or minor vibrations, making the rotational movement of the linkage rod 41 smoother.

[0034] In some embodiments, see Figure 1 and Figure 2 The positioning component 20 includes a sliding pin 21, and the linkage part 411 has a sliding hole 413. The extension direction of the sliding hole 413 is the same as the extension direction of the linkage part 411. The sliding pin 21 is slidably disposed in the sliding hole 413. When the linkage part 411 rotates, the sliding pin 21 can slide along the sliding hole 413. The sliding pin 21 can be a cylindrical structure, and the sliding hole 413 can be a strip-shaped hole. Through the cooperation between the sliding hole 413 and the sliding pin 21, when the linkage part 411 rotates, the sliding pin 21 can be pulled to move in a straight line, thereby causing the positioning component 20 to move in a straight line.

[0035] In some embodiments, see Figure 1 and Figure 2The positioning component 20 also includes a second roller 22, which is rotatably connected to the sliding pin 21 and slidably disposed in the sliding hole 413. The second roller 22 can be a bearing or similar component. By providing the second roller 22 on the sliding pin 21, the sliding friction between the sliding pin 21 and the sliding hole 413 can be converted into rolling friction, further reducing energy loss and improving the movement efficiency of the positioning component 20. Rolling friction causes less wear on mechanical parts. Compared to sliding friction, the design of the second roller 22 reduces wear on the sliding pin 21 and the sliding hole 413, thereby extending the service life of the components. The rolling contact method of the second roller 22 reduces movement jamming or shaking caused by uneven surfaces or minor vibrations, making the movement of the positioning component 20 smoother.

[0036] In some embodiments, see Figure 1 , Figure 2 and Figure 3 The positioning component 20 includes a sliding frame 23 and a positioning seat 24. The sliding frame 23 is slidably disposed on the base 11, and the positioning seat 24 is connected to the side of the sliding frame 23 opposite to the base 11. The positioning seat 24 is configured to support and position the first workpiece 200 and the second workpiece 300. The sliding frame 23 can be a U-shaped structure. In this embodiment, the sliding frame 23 and the base 11 can be slidably connected by a slide rail or the like to improve the stability of the movement of the sliding frame 23. A sliding pin 21 can be disposed on the sliding frame 23 to drive the sliding frame 23 to the linkage rod 41. The positioning seat 24 can be a plate-like structure. The positioning seat 24 can be customized according to the shape and size of the workpiece to achieve high-precision positioning. For example, the positioning seat 24 can be designed as a groove or clamp that matches the shape of the first workpiece 200 to ensure that the first workpiece 200 does not move during the pressing process.

[0037] In some embodiments, see Figure 1 and Figure 3 The positioning component 20 also includes multiple positioning pins 25, all of which are located on the side of the positioning seat 24 opposite to the sliding frame 23. Each positioning pin 25 is configured to pass through the first workpiece 200 to position it. In this embodiment, the first workpiece 200 may have multiple holes, and the number and position of the positioning pins 25 correspond to the number and position of the holes on the first workpiece 200, such as two, three, or four. Positioning the first workpiece 200 is achieved simply by passing the multiple positioning pins 25 through it. It is understood that the dimensions of the multiple positioning pins 25 can be different to prevent incorrect placement of the first workpiece 200. Similarly, the second workpiece 300 may also have multiple holes, allowing it to be positioned using the multiple positioning pins 25.

[0038] In some embodiments, see Figure 1 and Figure 3 The positioning assembly 20 also includes a cover plate 26, which has pressing holes 261 and multiple positioning holes 262. The pressing holes 261 are adapted to the pressing head 32 and are configured to position the second workpiece 300. The multiple positioning holes 262 correspond one-to-one with multiple positioning pins 25, and the multiple positioning holes 262 cooperate with the multiple positioning pins 25 to position the cover plate 26. The number and position of the positioning holes 262 are consistent with the number and position of the positioning pins 25, thus enabling precise positioning of the cover plate 26. The number and position of the pressing holes 261 on the cover plate 26 are consistent with the number and position of the second workpiece 300 to be placed. By setting the pressing holes 261, the second workpiece 300 can be positioned. Furthermore, the pressing holes 261 are adapted to the pressing head 32, ensuring that the pressing head 32 accurately acts on the predetermined position of the second workpiece 300 during the pressing process, improving the pressing accuracy and avoiding pressing quality problems caused by the positional deviation of the pressing head 32.

[0039] In some embodiments, see Figure 1 The pressing assembly 30 also includes a guide plate 34 and guide posts 35. The guide plate 34 is connected to the pressing drive 31 and disposed between the pressing drive 31 and the pressing head 32. The guide post 35 is connected to the base 11 and slides through the guide plate 34. The guide plate 34 and guide post 35 cooperate to limit the movement direction of the pressing head 32. In this embodiment, the guide plate 34 is connected to the pressing drive 31, the pressing head 32 is connected to the guide plate 34, and multiple guide posts 35 can be provided, such as two, three, or four. A linear bearing or similar device can be provided between the guide post 35 and the guide plate 34. Through the cooperation of the guide plate 34 and guide post 35, the movement direction of the pressing head 32 can be precisely limited, ensuring that the pressing head 32 moves vertically along a straight line, effectively preventing the pressing head 32 from deviating or tilting during movement, thereby improving the pressing accuracy and ensuring that the pressing force is uniformly applied to the surface of the second workpiece 300.

[0040] The working process of the pressing device 100 provided in this embodiment is roughly as follows:

[0041] First, the first workpiece 200 is placed on the positioning seat 24 and positioned using the positioning pin 25. Then, the cover plate 26 is placed on the positioning seat 24 and positioned using the engagement of the positioning pin 25 and the positioning hole 262, pressing the cover plate 26 against the first workpiece 200. Next, the second workpiece 300 is placed in the pressing hole 261 of the cover plate 26, positioning the second workpiece 300 while simultaneously bringing it into contact with the first workpiece 200, thus completing the loading process.

[0042] After the material is loaded, the pressing drive 31 drives the guide plate 34, the pressing head 32, and the pushing member 33 to move toward the base 11. The guide plate 34, in conjunction with the guide column 35, restricts the movement direction of the pressing head 32 and the pushing member 33 to improve the pressing accuracy. The pushing member 33 pushes the first roller 45 to move toward the base 11, thereby driving the drive part 412 of the linkage rod 41 to rotate closer to the base 11. The drive part 412 drives the linkage part 411 to rotate away from the base 11. The linkage part 411, through the cooperation of the sliding hole 413, the second roller 22, and the sliding pin 21, pulls the sliding frame 23 to move toward the support frame 12, thereby driving the positioning seat 24, the first workpiece 200, and the second workpiece 300 to move below the pressing head 32. The pressing head 32 passes through the pressing hole 261 to press the first workpiece 200 and the second workpiece 300.

[0043] After pressing is completed, the pressing drive 31 drives the guide plate 34, the pressure head 32 and the pusher 33 to move away from the base 11. The pusher 33 moves away from the first roller 45. The reset elastic member 44 pushes the snap-fit ​​member 43 to move, thereby driving the linkage part 411 to rotate and move closer to the base 11. The linkage part 411 drives the sliding frame 23 to move away from the support frame 12 through the cooperation of the sliding hole 413, the second roller 22 and the sliding pin 21. This makes the first workpiece 200 and the second workpiece 300 after pressing move away from below the pressure head 32, which is convenient for unloading.
