Description

Technical Field

[0001] This application relates to the field of bonding technology for small parts and workpieces, and specifically to a bonding device. Background Technology

[0002] In actual production and processing, it is often necessary to combine miniature parts with workpieces. Currently, welding and adhesive bonding are the main methods used to combine these parts. However, welding is limited by the materials of the parts and workpieces and is not suitable for bonding metal and non-metal materials; adhesive bonding is limited by the small adhesive area of ​​the parts, resulting in insufficient bond strength between the parts and workpieces, failing to meet the required bonding strength. Utility Model Content

[0003] In view of the above, it is necessary to propose a bonding device to automatically assemble small parts and workpieces of different materials, while meeting the bonding strength requirements between the small parts and workpieces.

[0004] This application provides a joining device for joining a small part and a workpiece, including:

[0005] The lower mold is used to hold the workpiece;

[0006] The upper mold is used to close with the lower mold and form a molding cavity;

[0007] A clamping assembly is used to clamp the small part and can be inserted into the upper mold so that the small part extends into the molding cavity. The clamping assembly includes a first clamping member, a second clamping member, a first top pin, and a locking member. The first clamping member and the second clamping member are connected and clamp the small part. The first top pin is telescopically disposed on the first clamping member and can push against the second clamping member. One end of the locking member is rotatably disposed on the first clamping member, and the other end of the locking member moves through the second clamping member and can rotate within the second clamping member. The locking member is used to lock the second clamping member to the first clamping member.

[0008] The push-opening component includes a second push pin that is retractably disposed on the upper mold and can push the first clamping member away from the second clamping member, wherein the second push pin can push the first clamping member away from the first clamping member;

[0009] A clamping mechanism is disposed on the upper mold and is used to clamp the clamping assembly onto the upper mold.

[0010] In some embodiments, the second clamping member includes a clamping portion, a middle portion, and a pressing portion connected in sequence. The pressing portion is connected to the middle portion. The second clamping member also includes a protrusion connected to the middle portion and abutting against the pressing portion. The first clamping member has a groove portion adapted to the protrusion portion. When the first clamping member and the second clamping member are connected, the clamping portion and the first clamping member clamp the small part. The other end of the locking member moves through the middle portion and can rotate within the clamping portion. The protrusion portion is adapted to be inserted into the groove portion, and the first top pin pushes the side of the protrusion portion away from the pressing portion. The pressing portion abuts against the side of the first clamping member.

[0011] In some embodiments, the clamping mechanism includes a base, a side pressure member, a sliding member, a side pressure elastic member, and a driving assembly. The base is disposed on the upper mold. The side pressure member is slidably disposed on the base and used to abut against the first clamping member. The sliding member is slidably disposed on the base and disposed above the side pressure member. The sliding member has a stop portion extending into the side pressure member. The side pressure elastic member is movably disposed on the side pressure member and abuts against the stop portion and the side pressure member. The driving assembly is disposed on the base and connected to the sliding member. The driving assembly is used to drive the sliding member closer to the first clamping member, so that the sliding member drives the side pressure member closer to and abuts against the first clamping member through the side pressure elastic member.

[0012] In some embodiments, the clamping mechanism further includes a top pressing member, a top blocking member, and a top pressing elastic member. The top pressing member is slidably disposed on the sliding member along the mold closing direction. The top pressing member is disposed above the side pressing member and abuts against the inclined surface of the side pressing member. The top blocking member is disposed on the sliding member and above the top pressing member. The top pressing elastic member abuts between the top blocking member and the top pressing member.

[0013] In some embodiments, the clamping mechanism further includes a side abutment and a side abutment elastic member. The side abutment is slidably disposed on the base and perpendicular to the side pressure member. The side abutment abuts against the inclined surface of the side pressure member and the sliding member away from the first clamping member. The side abutment elastic member is movably disposed within the base and abuts against the side abutment and the base.

[0014] In some embodiments, the drive assembly includes a cover plate, a rotating member, an eccentric member, and a linkage member. The cover plate is connected to the base and disposed above the base. The rotating member is rotatably disposed on the cover plate. The eccentric member is eccentrically connected to the rotating member and disposed below the rotating member. The linkage member is slidably disposed on the base and connected to the rotating member. The linkage member has a strip groove, and the eccentric member is inserted into the strip groove.

[0015] In some embodiments, the drive assembly further includes a positioning seat, a positioning elastic element, and a positioning ball. The positioning seat is connected to the rotating element and is disposed above the cover plate. There are two positioning elastic elements and two positioning balls. The two positioning elastic elements are spaced apart on the base and are respectively located on both sides of the rotating element. The two positioning balls are respectively connected to the two positioning elastic elements. Each positioning ball can pass through the cover plate and be inserted into the positioning seat under the action of the corresponding positioning elastic element.

[0016] In some embodiments, the upper mold has an insertion hole communicating with the molding cavity, and the upper mold also has two limiting portions, which are respectively disposed on both sides of the insertion hole. The first clamping member has protruding wings on both sides. The clamping assembly is inserted into the insertion hole, and the two wings abut against the two limiting portions respectively. The pressing mechanism is used to press the clamping assembly against the two limiting portions. The second top pin has two pins and is retractably disposed in the two limiting portions respectively.

[0017] In some embodiments, the clamping assembly further includes a first elastic member movably disposed within the first clamping member and abutting against the first top pin and within the first clamping member.

[0018] In some embodiments, the ejector assembly further includes a second elastic member, which is movably disposed on the upper mold and abuts against the second ejector pin and the upper mold.

[0019] In actual use, the above-mentioned connecting device involves placing the workpiece on the lower mold, then closing the upper and lower molds to position the workpiece within the molding cavity. A small part is placed on the first clamping member, and a second clamping member is connected to the first clamping member to hold the small part. The other end of the locking member moves through the second clamping member. The first top pin retractably pushes against the second clamping member. After the second and first clamping members hold the small part, the locking member is rotated within the second clamping member, causing its other end to rotate towards the second clamping member, thus connecting the other end of the locking member to the second clamping member, locking the second clamping member to the first clamping member. The clamping assembly for holding the small part is inserted into the upper mold, allowing the small part to extend into the molding cavity and connect with the workpiece. The second top pin retractably pushes against the first clamping member. After the clamping assembly is inserted into the upper mold, a clamping mechanism presses the clamping assembly against the upper mold. After the clamping assembly is pressed, glue is injected into the molding cavity to allow the small part to pass through the mold. The adhesive is applied to the workpiece. After the small part is bonded to the workpiece, the locking component is rotated in the opposite direction, causing the other end of the locking component to separate from the second clamping component. At this time, the first ejector pin retractably pushes against the second clamping component, causing the second clamping component to tend to move away from the first clamping component. At the same time, the second ejector pin retractably pushes against the first clamping component, causing the first clamping component to tend to move away from the second clamping component. This causes the clamping mechanism to release the clamping assembly. After the clamping mechanism releases the clamping assembly, the first clamping component and the second clamping component spring apart and separate under the pushing action of the second ejector pin and the first ejector pin, respectively, creating a gap. That is, the first clamping component and the second clamping component can no longer hold the small part. The separated first clamping component and the second clamping component are removed from the upper mold. Since the first clamping component and the second clamping component cannot hold the small part, the small part will not be carried out with the first clamping component and the second clamping component. The upper mold and the lower mold are then separated, and the bonded small part and the workpiece are removed, thus achieving the bonding of the small part and the workpiece.

[0020] The bonding device provided in this application embodiment, through the coordinated cooperation of the lower mold, upper mold, clamping assembly, ejection assembly and pressing mechanism, combines small parts and workpieces by potting glue, so as to realize the automated assembly of small parts and workpieces of different materials and meet the bonding strength requirements of small parts and workpieces. In addition, the first clamping part and the second clamping part are springed apart and separated under the pushing action of the second top pin and the first top pin respectively, creating a gap, so that the small parts will not be carried out with the first clamping part and the second clamping part, ensuring the bonding yield of small parts and workpieces.

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

[0032] The following will describe some embodiments of this application in detail with reference to the accompanying drawings.

[0033] Please see Figure 1 This application provides a connecting device 100 for connecting a small part 200 (see [link]). Figure 3 (and workpiece (not shown in the figure). Please refer to [reference needed]. Figure 2 The connecting device 100 includes a lower mold 10, an upper mold 20, a clamping assembly 30, an opening assembly 40, and a pressing mechanism 50.

[0034] The lower mold 10 is used to hold the workpiece. The upper mold 20 is used to close with the lower mold 10 to form a molding cavity 21, wherein the workpiece is located in the molding cavity 21. The upper mold 20 is also provided with a glue inlet 22 communicating with the molding cavity 21. It can be understood that in other embodiments, the glue inlet 22 may also be provided on the lower mold 10.

[0035] Please refer to the above. Figure 3 and Figure 4The clamping assembly 30 is used to clamp the small part 200 and can be inserted into the upper mold 20, so that the small part 200 extends into the molding cavity 21 and connects with the workpiece in the molding cavity 21. The clamping assembly 30 includes a first clamping member 31, a second clamping member 32, a first ejector pin 33, and a locking member 34. The first clamping member 31 and the second clamping member 32 are adapted to be connected and clamp the small part 200. The first ejector pin 33 is telescopically disposed in the first clamping member 31 and can push against the second clamping member 32. The telescopically disposed first ejector pin 33 in the first clamping member 31 can be understood as the first ejector pin 33 retracting into the first clamping member 31 when subjected to external force, and partially extending out of the first clamping member 31 when the external force is removed. One end of the locking member 34 is rotatably disposed on the first clamping member 31, and the other end of the locking member 34 moves through the second clamping member 32 and can rotate within the second clamping member 32. The locking member 34 is used to lock the second clamping member 32 to the first clamping member 31. That is, by rotating the locking member 34 within the second clamping member 32, the other end of the locking member 34 rotates toward the locking member 34, thereby locking the second clamping member 32 to the first clamping member 31, so that the first clamping member 31 and the second clamping member 32 clamp the small part 200. The clamping assembly 30 may further include a first elastic element 35, which may be a spring. The first elastic element 35 is movably disposed within the first clamping member 31 and abuts against the first top pin 33 and the second clamping member 32. The first elastic element 35 provides elastic force to the first top pin 33 so that the first top pin 33 is retractably disposed within the first clamping member 31 and can elastically push against the second clamping member 32. The first top pin 33 has a generally stepped structure so that the first top pin 33 will not detach from the first clamping member 31.

[0036] The ejector assembly 40 includes a second ejector pin 41 that is telescopically disposed on the upper mold 20 and can push against the first clamping member 31. The second ejector pin 41 can push the first clamping member 31 away from the second clamping member 32, and the first ejector pin 33 can push the second clamping member 32 away from the first clamping member 31. It can also be understood that when the clamping assembly 30 is inserted into the upper mold 20, if the locking member 34 does not lock the first clamping member 31 and the second clamping member 32, the first clamping member 31 and the second clamping member 32 will spring open and separate under the push of the second ejector pin 41 and the first ejector pin 33 respectively, creating a gap, thereby failing to clamp the small part 200. The ejector assembly 40 may further include a second elastic element 42, which may be a spring. The second elastic element 42 is movably disposed on the upper mold 20 and abuts against the second ejector pin 41 and within the upper mold 20. The second elastic element 42 provides elastic force to the second ejector pin 41, allowing the second ejector pin 41 to be retractably disposed on the upper mold 20 and elastically push against the first clamping member 31. The second ejector pin 41 has a generally stepped structure to prevent it from detaching from the upper mold 20. Furthermore, the ejector assembly 40 may also include a mounting base 43, which is disposed within the upper mold 20. The second elastic element 42 abuts between the mounting base 43 and the second ejector pin 41 to facilitate the assembly of the ejector assembly 40 on the upper mold 20.

[0037] The clamping mechanism 50 is disposed on the upper mold 20 and is used to clamp the clamping assembly 30 onto the upper mold 20.

[0038] In actual use, the coupling device 100 of this embodiment places the workpiece on the lower mold 10, then closes the upper mold 20 with the lower mold 10 and positions the workpiece in the forming cavity 21. The small part 200 is placed on the first clamping member 31, and the second clamping member 32 is connected to the first clamping member 31 to clamp the small part 200, allowing the other end of the locking member 34 to move through the second clamping member 32. The first top pin 33 can extend and retract to push against the second clamping member 32. After the second clamping member 32 and the first clamping member 31 clamp the small part 200, the locking member 34 is rotated within the second clamping member 32 to engage the locking member. The other end of the locking member 34 rotates toward the second clamping member 32, thereby connecting the other end of the locking member 34 with the second clamping member 32 to lock the second clamping member 32 to the first clamping member 31. The clamping assembly 30 for clamping the small part 200 is inserted into the upper mold 20, allowing the small part 200 to extend into the molding cavity 21 and connect to the workpiece. The second top pin 41 is telescopically abutting against the first clamping member 31. After the clamping assembly 30 is inserted into the upper mold 20, the clamping mechanism 50 presses the clamping assembly 30 against the upper mold 20. After the clamping assembly 30 is pressed, glue is injected into the molding cavity 21 through the glue inlet 22. The small part 200 is bonded to the workpiece by the cured adhesive. After the small part 200 is bonded to the workpiece, the locking member 34 is rotated in the reverse direction, causing the other end of the locking member 34 to separate from the second clamping member 32. At this time, the first top pin 33 retractably pushes against the second clamping member 32, causing the second clamping member 32 to tend to move away from the first clamping member 31. At the same time, the second top pin 41 retractably pushes against the first clamping member 31, causing the first clamping member 31 to tend to move away from the second clamping member 32. This causes the clamping mechanism 50 to release the clamping assembly 30. After the clamping mechanism 50 releases the clamping assembly 30, the first clamping member 30... Clamping member 31 and second clamping member 32 are separated by the pushing action of second top pin 41 and first top pin 33, respectively, and a gap is generated. That is, the first clamping member 31 and the second clamping member 32 cannot clamp the small part 200. The separated first clamping member 31 and second clamping member 32 are taken out from the upper mold 20. Since the first clamping member 31 and the second clamping member 32 cannot clamp the small part 200, the small part 200 will not be taken out with the first clamping member 31 and the second clamping member 32. The upper mold 20 and the lower mold 10 are separated, and the combined small part 200 and the workpiece are taken out, realizing the combination of small part 200 and workpiece.

[0039] In this embodiment, there are two sets of clamping components 30 and four sets of ejector components 40. Each set of clamping components 30 corresponds to two sets of ejector components 40, that is, the two sets of ejector components 40 are spaced apart on the upper mold 20 and respectively located on both sides of the corresponding clamping component 30, so as to provide a balanced pushing force for the clamping component 30. There is one clamping mechanism 50, which can simultaneously clamp two sets of clamping components 30 onto the upper mold 20. It is understood that in other embodiments, the number of clamping components 30, ejector components 40 and clamping mechanisms 50 may be more or less, which can be set according to the actual production situation. This application embodiment does not specifically limit this.

[0040] In order to ensure stable mold closing between the upper mold 20 and the lower mold 10, in this embodiment, the lower mold 10 may include a mold base 11 and a mold closing handle 12. The mold base 11 is used to hold the workpiece, and there are two mold closing handles 12. The two mold closing handles 12 are respectively rotatably disposed on both sides of the mold base 11. When the upper mold 20 and the mold base 11 are closed, the two mold closing handles 12 are rotated to connect to both sides of the upper mold 20, thereby ensuring stable mold closing between the upper mold 20 and the lower mold 10.

[0041] In this embodiment, the second clamping member 32 includes a clamping portion 321, a middle portion 322, and a pressing portion 323 connected in sequence. The pressing portion 323 is connected to the middle portion 322. In this embodiment, the pressing portion 323 is perpendicularly connected to the middle portion 322. The second clamping member 32 also includes a protrusion 324 connected to the middle portion 322 and abutting against the pressing portion 323. The first clamping member 31 has a groove 311 adapted to the protrusion 324. When the first clamping member 31 is connected to the second clamping member 32, the clamping portion 321 and the first clamping member 31 are adapted to clamp the small part 200. The other end of the locking member 34 moves through the middle portion 322 and can rotate within the clamping portion 321. The protrusion 324 is adapted to be inserted into the groove 311, and the first top pin 33 pushes the side of the protrusion 324 away from the pressing portion 323. The pressing portion 323 abuts against the side of the first clamping member 31. Thus, by setting the specific structure of the second clamping member 32, the first clamping member 31 and the second clamping member 32 can be tightly and stably connected through the fitting and insertion of the protrusion 324 and the groove 311. The middle part 322 has a through hole 325, through which the other end of the locking member 34 moves movably.

[0042] In this embodiment, the first clamping member 31 is further provided with an assembly groove 312 and a protruding hole 313. The assembly groove 312 is located in the middle of the first clamping member 31, and the protruding hole 313 connects the assembly groove 312 and the recessed portion 311. The other end of the locking member 34 is rotatably disposed in the assembly groove 312, and the first top pin 33 and the first elastic member 35 are movably disposed in the protruding hole 313, with the first top pin 33 protruding out of the protruding hole 313. Thus, by providing the assembly groove 312 and the protruding hole 313 on the first clamping member 31, the locking member 34, the first top pin 33, and the first elastic member 35 can be assembled.

[0043] In this embodiment, the first clamping member 31 has protruding wings 314 on both sides. The upper mold 20 has an insertion hole 23 communicating with the forming cavity 21. The upper mold 20 also has two limiting parts 24, which are respectively disposed on both sides of the insertion hole 23 and extend into the insertion hole 23. The clamping assembly 30 is inserted into the insertion hole 23 and is located between the two limiting parts 24 and the insertion hole 23. The two wings 314 abut against the top of the two limiting parts 24. The pressing mechanism 50 is used to press the clamping assembly 30 against the two limiting parts 24. The number of insertion holes 23 is equal to the number of clamping assemblies 30. The number of limiting parts 24 is four. Each insertion hole 23 is provided with two limiting parts 24 and two sets of opening assemblies 40. Each second top pin 41 is telescopically disposed in the corresponding limiting part 24 through a corresponding second elastic member 42 and a corresponding mounting seat 43. Thus, by providing the wing 314, the second top pin 41 can push against the first clamping member 31. By providing the limiting part 24, the limiting part 24 cooperates with the pressing mechanism 50 to press the clamping assembly 30 against the upper mold 20.

[0044] Please refer to the above. Figure 5 , Figure 6 and Figure 7In this embodiment, the clamping mechanism 50 includes a base 51, a side-pressing member 52, a sliding member 53, a side-pressing elastic member 54, and a driving assembly 55, wherein the number of the side-pressing member 52, the sliding member 53, and the side-pressing elastic member 54 is equal to the number of the clamping assembly 30. The base 51 is disposed on the upper mold 20 and adjacent to the insertion hole 23. The side pressure member 52 is slidably disposed on the base 51 and is used to abut against the first clamping member 31. The sliding member 53 is slidably disposed on the base 51 and is disposed above the side pressure member 52. The sliding member 53 has a stop portion 531 extending into the side pressure member 52. The side pressure elastic member 54 can be a spring. The side pressure elastic member 54 is movably disposed in the side pressure member 52 and abuts against the stop portion 531 and the side pressure member 52. The side pressure elastic member 54 is located on the side of the stop portion 531 facing the first clamping member 31. The driving assembly 55 is disposed on the base 51 and connected to both sliding members 53. The driving assembly 55 is used to drive the sliding member 53 to approach the first clamping member 31, so that the sliding member 53 drives the side pressure member 52 to approach and abut against the first clamping member 31 through the side pressure elastic member 54. Understandably, the base 51 is provided with slotted structures for accommodating and accommodating objects such as the side pressure member 52 and the sliding member 53, which will not be described in detail in this embodiment. The sliding member 53 also has protruding sliding portions 532 on both sides, through which the sliding member 53 slides and is stopped by the base 51.

[0045] Thus, by setting the base 51, side pressure member 52, sliding member 53, side pressure elastic member 54 and driving assembly 55 as described above, when the clamping assembly 30 is inserted into the insertion hole 23 and abuts against the limiting part 24, the driving assembly 55 drives the sliding member 53 to move toward the first clamping member 31. The sliding member 53 compresses the side pressure elastic member 54, causing the side pressure elastic member 54 to generate elastic force. At the same time, the side pressure elastic member 54 releases the elastic force to drive the side pressure member 52 to move closer to the first clamping member 31, and the side pressure member 52 abuts against the first clamping member 31. Through the elastic force of the side pressure elastic member 54, the side pressure member 52 can elastically and stably abut against the first clamping member 31. Since the clamping assembly 30 is also restricted by the limiting part 24, the clamping assembly 30 is stably fixed, ensuring the accuracy of the small part 200.

[0046] To further press the clamping assembly 30 against the upper mold 20 along the mold closing direction, in this embodiment, the clamping mechanism 50 also includes a top pressing member 56, a top blocking member 57, and a top pressing elastic member 58. The top pressing member 56 can be L-shaped and is slidably disposed within the sliding member 53 along the mold closing direction. The top pressing member 56 is disposed above the side pressing member 52 and abuts against the inclined surface of the side pressing member 52. The bottom of the top pressing member 56 is approximately conical. The top blocking member 57 is approximately plate-shaped and is disposed at the top of the sliding member 53 and above the top pressing member 56. The top pressing elastic member 58 can be a spring and abuts between the top blocking member 57 and the top pressing member 56. The shape of the sliding member 53 is adapted to the top pressing member 56 and other objects, and the top pressing elastic member 58 is movably embedded within the top pressing member 56.

[0047] Thus, by setting the aforementioned top pressure member 56, top stop member 57, and top pressure elastic member 58, when the clamping mechanism 50 is in the state of releasing the clamping assembly 30, that is, when the side pressure member 52 is not abutting against the first clamping member 31, the side pressure member 52 abuts against the inclined surface of the top pressure member 56, causing the top pressure member 56 to move upward and compress the top pressure elastic member 58. When the drive assembly 55 drives the sliding member 53 to move towards the first clamping member 31, the top pressure member 56, top stop member 57, and top pressure elastic member 58 move synchronously with the sliding member 53. When the side pressure member 52 abuts against the first clamping member 31, the top pressure member 56, top stop member 57, and top pressure elastic member 58 move synchronously with the sliding member 53. When clamping component 31 is in place, the side pressure component 52 cannot continue to move due to the restriction effect of the first clamping component 31. At this time, the sliding component 53, the top pressure component 56, the top stop component 57 and the top pressure elastic component 58 continue to move toward the first clamping component 31. Since the top pressure component 56 is no longer abutted by the inclined surface of the side pressure component 52, the top pressure component 56 moves downward under the elastic force of the top pressure elastic component 58 and abuts against the second clamping component 32, thereby achieving the clamping of the clamping assembly 30 along the mold closing direction, and further pressing the clamping assembly 30 against the upper mold 20 along the mold closing direction.

[0048] To prevent the side pressure member 52 and the sliding member 53 from detaching from the base 51, in this embodiment, the clamping mechanism 50 further includes a side abutment member 591 and a side abutment elastic member 592. The side abutment member 591 is slidably disposed on the base 51 and perpendicular to the side pressure member 52. The side abutment member 591, the side pressure member 52, and the sliding member 53 are all in inclined contact at the ends opposite to the first clamping member 31. The side abutment elastic member 592 is movably disposed within the base 51 and abuts between the side abutment member 591 and the base 51. Thus, by setting the aforementioned side abutment 591 and side abutment elastic member 592, when the side pressure member 52 and the sliding member 53 move away from the clamping assembly 30, the side pressure member 52 and the sliding member 53 abut against the side abutment 591 through the inclined surface cooperation. The side abutment 591 compresses the side abutment elastic member 592 and further abuts against the side pressure member 52 and the sliding member 53 tightly under the elastic force of the side abutment elastic member 592, so that the side pressure member 52 and the sliding member 53 can be fixed in the base 51, preventing the side pressure member 52 and the sliding member 53 from coming out of the base 51, and ensuring the stable use of the clamping mechanism 50.

[0049] In this embodiment, the drive assembly 55 includes a cover plate 550, a rotating member 551, an eccentric member 552, and a linkage member 553. The cover plate 550 is connected to the base 51 and is disposed above the base 51. The rotating member 551 is rotatably disposed on the cover plate 550. The eccentric member 552 is eccentrically connected to the rotating member 551 and is disposed below the rotating member 551. The linkage member 553 has a roughly cross-shaped structure. The linkage member 553 is slidably disposed on the base 51, and both ends of the linkage member 553 are respectively connected to two sliding members 53. The linkage member 553 has a strip groove 554. The eccentric member 552 is inserted into the strip groove 554. The extension direction of the strip groove 554 is perpendicular to the movement direction of the sliding member 53. Thus, by setting the cover plate 550, firstly, it covers the sliding member 53, the side pressing member 52, the side abutment member 591, etc., to ensure the stability of the pressing mechanism 50; secondly, it assembles the rotating member 551. By setting the rotating member 551, the eccentric member 552 and the linkage member 553, when the rotating member 551 is rotated in the forward or reverse direction, the rotating member 551 drives the eccentric member 552 to rotate eccentrically. The eccentric member 552 drives the linkage member 553 to move linearly through the eccentric movement and the strip groove 554. The linkage member 553 drives the two sliding members 53 to move linearly, thereby driving the sliding members 53 to move.

[0050] To ensure the driving accuracy of the drive assembly 55, in this embodiment, the drive assembly 55 further includes a positioning seat 555, a positioning elastic element 556, and a positioning ball 557. The positioning seat 555 is connected to the rotating element 551 and is disposed above the cover plate 550. The positioning elastic element 556 can be a spring. There are two positioning elastic elements 556 and two positioning balls 557. The two positioning elastic elements 556 are spaced apart on the base 51 and located on both sides of the rotating element 551. The two positioning elastic elements 556 are movably embedded in the base 51. The two positioning balls 557 are respectively connected to the two positioning elastic elements 556. Each positioning ball 557 can pass through the cover plate 550 and insert into the positioning seat 555 under the action of the corresponding positioning elastic element 556. Specifically, the side of the positioning seat 555 facing the cover plate 550 has a ball groove adapted to the positioning ball 557. Thus, when the positioning seat 555 and the rotating component 551 are rotated, if the positioning ball 557 is inserted into the ball groove under the action of the positioning elastic component 556, it indicates that the positioning seat 555 and the rotating component 551 have rotated into place, thereby ensuring the driving accuracy of the drive assembly 55.

[0051] To further limit the positioning seat 555, in this embodiment, the drive assembly 55 also includes two limiting blocks 558. The two limiting blocks 558 are spaced apart on the top of the cover plate 550, and each limiting block 558 is used to limit the positioning seat 555. Thus, by setting the above-mentioned limiting blocks 558, when the positioning seat 555 and the rotating component 551 are rotated, the limiting blocks 558 limit and stop the positioning seat 555, ensuring the rotational accuracy of the positioning seat and the rotating component 551.

[0052] To ensure the smooth rotation of the positioning seat 555, in this embodiment, the drive assembly 55 further includes a bearing handle 559. The bearing handle 559 is rotatably connected to the end of the positioning seat 555 away from the rotating component 551 and is disposed on the side of the positioning seat 555 opposite to the cover plate 550. Thus, by providing the bearing handle 559 and limiting the rotatable connection between the bearing handle 559 and the positioning seat 555, the positioning seat 555 can be easily rotated by driving the bearing handle 559, thereby ensuring the smooth rotation of the positioning seat 555.

[0053] The bonding device 100 provided in this application embodiment, through the coordinated cooperation of the lower mold 10, upper mold 20, clamping assembly 30, ejection assembly 40 and pressing mechanism 50, bonds the small part 200 and the workpiece by potting glue, solving the problem of bonding between different materials and meeting the bonding strength requirements. In addition, the first clamping member 31 and the second clamping member 32 are ejected and separated under the pushing action of the second ejector pin 41 and the first ejector pin 33, respectively, and a gap is generated, so that the small part 200 will not be carried out with the first clamping member 31 and the second clamping member 32, ensuring the bonding yield of the small part 200 and the workpiece.
