Description

Technical Field

[0001] This invention belongs to the field of automation, specifically relating to a fully automatic foam bonding equipment assembly. Background Technology

[0002] Foam is a material made by foaming plastic particles. It possesses a range of characteristics including elasticity, light weight, quick compression and fixing, ease of use, flexibility, ultra-thinness, and reliable performance. Foam structures are often found attached to car door handles, primarily serving to prevent impacts and provide protection.

[0003] Traditional manual foam placement methods, relying on human labor, have several limitations in terms of speed and consistency. Firstly, the speed of manual operation is limited by the operator's skill level and physical condition, easily leading to an unstable work rhythm. Secondly, during prolonged repetitive work, operators may experience fatigue and decreased concentration, increasing the error rate. Furthermore, because the workpiece has multiple positioning slots in different positions awaiting foam placement, and these slots are often placed downwards after injection molding, collisions and damage to the workpiece are inevitable during operation, especially when moving or flipping it. In addition, variations in individual operating techniques can easily lead to quality fluctuations even within the same batch of products. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the existing technology, the technical problem to be solved by the present invention is to provide a fully automatic foam bonding equipment assembly.

[0005] The technical solution adopted by the present invention to solve its technical problem is to propose a fully automatic foam bonding equipment assembly for sequentially bonding several foams onto a workpiece, wherein the workpiece has several positioning grooves distributed on the same outer wall and not collinearly arranged, and the foam is movably bonded to the positioning grooves. The bonding equipment includes: a frame, which is set on one side of an injection molding machine, and a receiving mechanism for gripping the processed workpiece is also provided between the frame and the injection molding machine.

[0006] The rotating mechanism and the film-applying mechanism are provided. The rotating mechanism is connected to a positioning seat at its movable end. The receiving mechanism is used to transfer the workpiece processed by the injection molding machine into the positioning seat, so that when the positioning seat is rotated relative to the frame, the openings of several positioning slots on the workpiece can face upwards. The film-applying mechanism can sequentially and movably apply several foams on the tape into the positioning slots.

[0007] The machine includes a material transfer mechanism and an adjustment mechanism. The material transfer mechanism is mounted on the frame, with one end close to the injection molding machine and the other end extending below the film application mechanism. It is used to move the positioning seat closer to or away from the film application mechanism. The adjustment mechanism is located at the drive end of the material transfer mechanism, and the flipping mechanism is mounted on the material transfer mechanism. The moving direction of the drive end of the adjustment mechanism is perpendicular to the moving direction of the drive end of the material transfer mechanism in the horizontal direction, and is used to adjust the position of the positioning groove on the workpiece relative to the film application mechanism.

[0008] The equipment includes a detection mechanism and a feeding mechanism. The detection mechanism is located below the positioning seat. When the foam is approaching the positioning seat from the opposite direction, the detection mechanism can detect the tightness of the foam in the positioning groove and then transfer it to the outside of the mounting equipment via the feeding mechanism on the frame.

[0009] In the aforementioned fully automatic foam bonding equipment assembly, the flipping mechanism includes:

[0010] Mounting bracket, which is equipped with mounting base and mounting plate;

[0011] A rotating shaft and a rotary motor are provided. The rotating shaft is rotatably mounted in the mounting base, and the positioning base is connected to the rotating shaft. The rotary motor is mounted on the mounting plate, and a coupling is provided between the output end of the rotary motor and the rotating shaft, so that the rotary motor can drive the positioning base to rotate when it is turned on.

[0012] In the above-mentioned fully automatic foam bonding equipment assembly, the bottom of the positioning seat is connected to a locking block, the locking block has interconnected engaging grooves and locking holes, the rotating shaft has a connecting hole along its radial direction, and both ends of the connecting hole have locking planes formed on the rotating shaft.

[0013] When the engaging groove is engaged on the rotating shaft and abuts against the locking plane, the locking hole and the connecting hole are interconnected, allowing the fixing member to pass through and restrict the movement of the positioning seat relative to the rotating shaft.

[0014] In the aforementioned fully automatic foam bonding equipment assembly, the flipping mechanism further includes:

[0015] An extension plate is connected to the positioning seat;

[0016] A clamping cylinder is disposed on the extension plate and located on one side of the positioning seat. The driving end of the clamping cylinder is connected to a clamping column. A positioning block and a contoured surface are formed inside the positioning seat. The clamping column is used to clamp the workpiece on the positioning block and the contoured surface.

[0017] In the above-mentioned fully automatic foam bonding equipment assembly, the material transfer mechanism includes a feeding servo module and a first guide rail arranged parallel to the frame. The movable end of the feeding servo module is connected to a material transfer plate, and the bottom wall of the material transfer plate is equipped with a first slider that is movably engaged with the first guide rail. The positioning mechanism includes a horizontal movement servo module and a second guide rail arranged parallel to the material transfer plate and perpendicular to the feeding servo module. The movable end of the horizontal movement servo module is connected to a moving bracket, and the bottom wall of the moving bracket is equipped with a second slider that is movably engaged with the second guide rail. The flipping mechanism and the detection mechanism are both arranged on the moving bracket.

[0018] In the above-mentioned fully automatic foam bonding equipment assembly, the detection mechanism includes a lifting component and several detectors. The lifting component is mounted on the movable support, and the several detectors are mounted on the driving end of the lifting component, so that when the lifting component is driven, it can drive the several detectors to move closer to or further away from the positioning seat in the vertical direction.

[0019] In the aforementioned fully automatic foam bonding equipment assembly, the film bonding mechanism includes:

[0020] The machine body is mounted on the frame and is equipped with a traction roller for placing the tape roll to unfold several foams on the tape roll in sequence.

[0021] The machine includes a receiving cylinder and an adsorption cylinder. The receiving cylinder is horizontally mounted on the machine body, and its drive end is connected to a receiving roller. The receiving roller is used to pull the belt to move so that the foam at the end of the belt is placed directly below the adsorption cylinder. The adsorption cylinder is vertically mounted on the machine body and located above the first guide rail near the end of the machine body. Its drive end is connected to an adsorption block.

[0022] When the adsorption block adsorbs the foam and detaches from the roll, the take-up cylinder drives the take-up roller to retract into the machine body, so that when the adsorption cylinder pushes the adsorption block closer to the positioning seat, it can press the foam into the positioning groove.

[0023] In the above-mentioned fully automatic foam bonding equipment assembly, the lifting component includes a lifting cylinder and a detection pressure head. The driving end of the lifting cylinder faces the positioning seat in a vertical direction, and a lifting plate is connected to the driving end. The detection pressure head and the detector are both mounted on the lifting plate.

[0024] In the above-mentioned fully automatic foam bonding equipment assembly, both the feeding mechanism and the receiving mechanism include a fixed frame and an adsorption plate. The fixed frame is connected to a robot or a linear guide rail, and an adjustment plate is connected to both ends of the fixed frame. The adsorption plate is arranged vertically on the adjustment plate to realize the gripping and placement of the workpiece.

[0025] In the above-mentioned fully automatic foam bonding equipment assembly, the adjusting plate has a first oblong hole and a second oblong hole that are not interconnected. The first oblong hole is used to adjust the installation position of the adjusting plate relative to the fixing frame. The adsorption plate is installed in the second oblong hole, and the position of the adsorption plate in the second oblong hole can be adjusted by tightening the locking nut.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] (1) The present invention integrates the fully automatic foam bonding equipment assembly with the injection molding machine, realizing unmanned production. At the same time, by using the cooperation of the feeding servo module and the transverse servo module, plus the rotation of the positioning seat driven by the rotating shaft, the precise adjustment of the position of the positioning groove on the workpiece is effectively realized, ensuring that the foam is quickly and stably bonded to the positioning groove, saving the overall working cycle time, avoiding the error caused by manual foam bonding and the outflow of defective products, and greatly ensuring production efficiency and workpiece quality.

[0028] (2) By using the locking groove on the locking block to abut against the locking plane on the rotating shaft, the positioning seat is always rotated synchronously with the rotating shaft without relative displacement. At the same time, under the pressure of the pressing column, the stability of the workpiece during foam installation is further guaranteed.

[0029] (3) Under the drive of the transverse servo module, the position of several non-collinear positioning slots on the workpiece can be adjusted. After the workpiece is flipped by the rotating shaft, it is directly moved to the bottom of the adsorption cylinder by the transverse servo module to complete the foaming process. The overall cycle time is short. At the same time, it integrates the automatic workpiece positioning and automatic foaming operation mode. While improving work efficiency, it also ensures that the fit between the workpiece and the foam can meet the customer's usage requirements. Attached Figure Description

[0046] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0047] like Figures 1 to 8 As shown, this invention discloses a fully automatic foam bonding equipment assembly for sequentially bonding several foams onto a workpiece. The workpiece has several positioning grooves distributed on the same outer wall and not collinearly arranged. The foams are movably bonded within these positioning grooves. The bonding equipment includes: a frame 11, positioned on one side of an injection molding machine 10; a receiving mechanism 2 for gripping the processed workpiece between the frame 11 and the injection molding machine 10; a flipping mechanism 3; and a film-applying mechanism 4. The movable end of the flipping mechanism 3 is connected to a positioning seat 30. The receiving mechanism 2 transfers the processed workpiece from the injection molding machine 10 into the positioning seat 30, so that when the positioning seat 30 flips relative to the frame 11, the openings of the positioning grooves on the workpiece face upwards. The film-applying mechanism 4 sequentially and movably bonds several foams from a roll of tape into the positioning grooves. The transfer mechanism 5 and the adjustment mechanism 6 are arranged on the frame 11. One end of the transfer mechanism 5 is close to the injection molding machine 10, and the other end extends to the bottom of the film application mechanism 4. It is used to drive the positioning seat 30 to move closer to or away from the film application mechanism 4. The adjustment mechanism 6 is arranged on the drive end of the transfer mechanism 5. The flipping mechanism 3 is installed on the transfer mechanism 5. The moving direction of the drive end of the adjustment mechanism 6 and the moving direction of the drive end of the transfer mechanism 5 are set perpendicular to each other in the horizontal direction. It is used to adjust the position of the positioning groove on the workpiece relative to the film application mechanism 4. The detection mechanism 7 and the unloading mechanism 8 are arranged below the positioning seat 30. The detection mechanism 7 can detect the tightness of the foam in the positioning groove when it is close to the positioning seat 30. The foam is then transferred to the outside of the mounting equipment by the unloading mechanism 8 on the frame 11.

[0048] In this embodiment, the main purpose is to sequentially attach several foam units into the positioning groove of the workpiece. Specifically, for example... Figures 1 to 8As shown, the equipment is integrated with the injection molding machine 10. After the workpiece is injection molded by the injection molding machine 10, the receiving mechanism 2 can pick up the workpiece from the injection molding machine 10 and place it into the positioning seat 30. It should be noted that after the workpiece is injection molded, the openings of several positioning grooves on the workpiece are all facing downwards. This also applies to the workpiece located in the positioning seat 30. Therefore, before the foam application process is started, the positioning seat 30 needs to be rotated 180° by the flipping mechanism 3 so that the openings of the positioning grooves on the workpiece are flipped upwards. Driven by the material transfer mechanism 5, the positioning seat 30 can be moved to the bottom of the film application mechanism 4 and the foam application operation can be completed directly. After the positioning seat 30 is reset by the material transfer mechanism 5, it is flipped again by the flipping mechanism 3. The detection mechanism 7 can then complete the workpiece quality detection function. Finally, the workpiece is unloaded and stacked for storage by the unloading mechanism 8. As can be seen, the fully automatic foam applicator is integrated with the injection molding machine 10, achieving unmanned production and avoiding the loss of defective products due to errors caused by manual foam applicator operation. Moreover, because the several positioning grooves on the workpiece are not on the same straight line, the adjustment mechanism 6 needs to adjust the overall position of the flipping mechanism 3. While ensuring the stability of the workpiece, it can also accurately adjust the position of the positioning groove of the foam to be applied on the workpiece, ensuring that the foam is quickly and stably attached to the positioning groove, saving the overall work cycle time and greatly ensuring production efficiency and workpiece quality.

[0049] The flipping mechanism 3 includes: a mounting frame 31 on which a mounting base 310 and a mounting plate 311 are mounted; a rotating shaft 32 and a rotary motor 33, wherein the rotating shaft 32 is rotatably mounted in the mounting base 310, and a positioning seat 30 is connected to the rotating shaft 32; the rotary motor 33 is mounted on the mounting plate 311, and a coupling 34 is provided between the output end of the rotary motor 33 and the rotating shaft 32, so that the rotary motor 33 can drive the positioning seat 30 to rotate when it is turned on.

[0050] like Figures 2 to 5 As shown, when the receiving mechanism 2 transfers the injection-molded workpiece into the positioning seat 30, the rotary motor 33, when turned on, drives the rotating shaft 32 to rotate within the mounting base 310 via the coupling 34. Since the positioning seat 30 is connected to the rotating shaft 32 via the mounting plate 311, the workpiece is synchronously rotated 180° with the positioning seat 30, placing the side of the workpiece with the positioning groove facing upwards. This facilitates the subsequent application of foam by the film-applying mechanism 4. The overall structure is relatively simple, avoiding the bumps and damage that can easily occur when manually flipping the workpiece. While ensuring the quality of the workpiece, it also saves cycle time for the overall foam-applying process, thereby improving production efficiency.

[0051] The bottom of the positioning seat 30 is connected to a locking block 35. The locking block 35 has an interconnected engagement groove 350 and a locking hole 351. The rotating shaft 32 has a connecting hole 320 along its radial direction. Both ends of the connecting hole 320 have locking surfaces 321 formed on the rotating shaft 32. When the engagement groove 350 is movably engaged on the rotating shaft 32 and abuts against the locking surface 321, the locking hole 351 and the connecting hole 320 are interconnected, so that the fixing member can pass through and restrict the movement of the positioning seat 30 relative to the rotating shaft 32.

[0052] Furthermore, such as Figures 4 to 5 As shown, regarding the connection between the positioning seat 30 and the rotating shaft 32, this embodiment has a locking block 35 detachably connected to the bottom of the positioning seat 30 via screws or other structures. During installation, the locking block 35 can be moved radially along the rotating shaft 32 using the engaging groove 350, allowing it to be movably engaged with the rotating shaft 32. It should be noted that the engaging groove 350 is U-shaped, and its two sides can adhere to the locking plane 321 as the locking block 35 engages, thus connecting the locking hole 351 and the connecting hole 320. This ensures that there is no relative slippage between the locking block 35 and the rotating shaft 32, and also achieves a fixed connection between the positioning seat 30 and the rotating shaft 32 when the fixing component passes through the locking hole 351 and the connecting hole 320, providing stability for the workpiece during flipping, repositioning, and quality inspection. It should be noted that the fixing component in this solution can also be replaced by screws, bolts, or other connecting parts.

[0053] Preferably, such as Figure 4 As shown, the flipping mechanism 3 in this embodiment also includes an extension plate 36 and a clamping cylinder 37. The extension plate 36 is connected to the positioning seat 30, and the clamping cylinder 37 is set on the extension plate 36 and located on one side of the positioning seat 30. When the receiving mechanism 2 transfers the workpiece in the injection molding machine 10 to the positioning seat 30, since the positioning seat 30 has a positioning block 300 and a contour surface 301, the positioning block 300 can be movably inserted into the workpiece as it is placed, which plays a guiding and positioning role when the workpiece is placed. At the same time, the design of the contour surface 301 makes the workpiece stably attached to the positioning seat 30. As the clamping cylinder 37 drives the clamping column 370 to clamp and fix the workpiece, it effectively prevents the workpiece from shifting relative to the positioning seat 30 or even falling off during the flipping process.

[0054] The material transfer mechanism 5 includes a feeding servo module 50 and a first guide rail 51 arranged parallel to the frame 11. The movable end of the feeding servo module 50 is connected to a material transfer plate 52. The bottom wall of the material transfer plate 52 is equipped with a first slider 53 that is movably engaged with the first guide rail 51. The positioning mechanism 6 includes a horizontal movement servo module 60 arranged parallel to the material transfer plate 52 and perpendicular to the feeding servo module 50, and a second guide rail 61. The movable end of the horizontal movement servo module 60 is connected to a moving bracket 62. The bottom wall of the moving bracket 62 is equipped with a second slider 63 that is movably engaged with the second guide rail 61. The flipping mechanism 3 and the detection mechanism 7 are both arranged on the moving bracket 62.

[0055] like Figure 2 and Figure 3 As shown, when the workpiece taken out from the injection molding machine 10 is clamped by the aforementioned clamping column 370 and rotated 180 degrees by the rotating shaft 32, the feeding servo module 50 can then move along... Figure 3 Moving from right to left, the entire adjustment mechanism 6, along with the flipping mechanism 3, moves closer to the film-applying mechanism 4, so that the foam inside the film-applying mechanism 4 can be firmly applied to the positioning groove of the workpiece. After completing the foam application operation in any positioning groove on the workpiece, the transverse servo module 60 can then drive the moving bracket 62 along... Figure 3 The movement in the front-back direction aligns the positioning slots at different positions with the underside of the film-applying mechanism 4, thereby enabling the automatic adjustment of several non-collinear positioning slots to meet the required film-applying process requirements. In other words, the complementary and synergistic action between the feeding servo module 50 and the traverse servo module 60 ensures that the positioning slots are adjusted to the positions required for foam application, avoiding errors caused by manual adjustment that could affect the quality of foam application on the workpiece. Furthermore, both the material transfer mechanism 5 and the positioning mechanism 6 utilize the movable engagement between the slider and the slide rail to ensure the smoothness and accuracy of the workpiece movement towards the film-applying mechanism 4 for foam application and the adjustment of the positioning slots on the workpiece. It should be noted that the working principle of the feeding servo module 50 and the traverse servo module 60 in this embodiment can be borrowed from linear guides. However, this driving method is not limited to the one described in this embodiment; a ball screw driving method can also be used as an alternative.

[0056] The film application mechanism 4 includes: a machine body 40, mounted on a frame 11, with a traction roller 41 on the machine body 40 for placing the roll of film to sequentially unfold several foam pieces on the roll of film; a take-up cylinder 42 and an adsorption cylinder 43. The take-up cylinder 42 is mounted horizontally on the machine body 40, and its drive end is connected to the take-up roller 420, which is used to traction the roll of film to place the foam pieces at the end of the roll of film directly below the adsorption cylinder 43; the adsorption cylinder 43 is mounted vertically on the machine body 40 and is located above the first guide rail 51 near the end of the machine body 40, with an adsorption block 430 connected to its drive end; when the adsorption block 430 adsorbs the foam pieces and detaches from the roll of film, the take-up cylinder 42 drives the take-up roller 420 to retract into the machine body 40, so that when the adsorption cylinder 43 pushes the adsorption block 430 close to the positioning seat 30, the foam pieces can be pressed into the positioning groove.

[0057] like Figure 2 and Figure 6 As shown, it should be noted that when the aforementioned feeding servo module 50 moves the positioning seat 30 below the adsorption cylinder 43, the workpiece inside the positioning seat 30 does not need to be disassembled and transferred to the machine body 40. Since the positioning seat 30 is located close to the take-up cylinder 42 and directly below the adsorption block 430 at this time, before attaching the foam, the worker or robot can place the entire roll of foam into the traction roller 41 (several pieces of foam are attached to the roll at intervals). As the take-up roller 420 pulls the roll, the foam on the roll is always at the very end. Thus, when the take-up cylinder 42 drives the take-up roller 420 to extend horizontally between the adsorption cylinder 43 and the positioning seat 30, the adsorption cylinder 43 can pre-drive the adsorption block 430 closer to the roll. After adsorbing and resetting the foam, the take-up cylinder 42 can then drive the take-up roller 420 to move horizontally... Figure 6 Moving to the left, so that the adsorption cylinder 43 can once again move the adsorption block 430 closer to the positioning seat 30, the foam on the adsorption block 430 is directly adhered to the positioning groove. By adjusting the placement position of the positioning groove on the workpiece relative to the machine body 40, the above foam-attaching action is repeated, thus quickly and automatically completing the foam-attaching process. This overall structure simplifies the foam-attaching operation, enabling rapid foam-attaching and, after the workpiece completes its corresponding process, allowing the feeding servo module 50 to seamlessly connect with subsequent inspection and unloading operations. This eliminates the need for clamping and secondary placement of the workpiece during foam-attaching in existing technologies, significantly reducing cycle time and improving production efficiency.

[0058] The detection mechanism 7 includes a lifting member 70 and several detectors 71. The lifting member 70 is mounted on the movable support 62, and the several detectors 71 are mounted on the driving end of the lifting member 70, so that when the lifting member 70 is driven, it can drive the several detectors 71 to move closer to or further away from the positioning seat 30 in the vertical direction.

[0059] Furthermore, such as Figure 4 As shown, after the foaming process is completed in several positioning slots on the workpiece, the feeding servo module 50 returns to its original position. Figure 3 When the initial position is shown, the rotary motor 33 can drive the positioning seat 30 to rotate to 180 degrees again. At this time, the lifting component 70 located at the bottom of the positioning seat 30 drives the detector 71 to move closer to the workpiece, and finally detects the position of the foam in each positioning groove on the workpiece to ensure that the foam is in the correct position with the positioning groove, effectively preventing the outflow of defective products.

[0060] Preferably, the lifting component 70 in this embodiment includes a lifting cylinder 700 and a detection pressure head 701. The driving end of the lifting cylinder 700 faces the positioning seat 30 in the vertical direction, and a lifting plate 702 is connected to the driving end. The detection pressure head 701 and the detector 71 are both mounted on the lifting plate 702. It should be noted that there is a certain distance between the lifting plate 702 and the positioning seat 30, which provides sufficient space for the positioning seat 30 to rotate the workpiece, effectively avoiding positional interference between the clamping column 370 or the workpiece and the detector 71, thus preventing collision damage. Therefore, after the workpiece is rotated, the lifting cylinder 700 needs to push the lifting plate 702 closer to the workpiece. When the detection pressure head 701 presses against the positioning seat 30, the detector 71 can start detecting the tightness and position of the positioning groove and the foam. In addition, multiple detectors 71 and detection heads 701 are used in this embodiment, and detector 71 can be replaced by other detection components such as position sensors and laser sensors.

[0061] Both the unloading mechanism 8 and the receiving mechanism 2 include a fixed frame 80 and an adsorption plate 81. The fixed frame 80 is connected to a robot or a linear guide rail, and an adjustment plate 82 is connected to both ends of the fixed frame 80. The adsorption plate 81 is arranged vertically on the adjustment plate 82 to realize the gripping and placement of the workpiece.

[0062] In this embodiment, as Figure 7 The feeding mechanism 8 shown is... Figure 8 The receiving mechanism 2 shown adopts a fixed frame 80 and suction cup 81 structure. Specifically, after the workpiece with attached foam passes the test of detector 71, the workpiece is flipped again by rotating shaft 32 and then moved by the movement of robot arm and linear guide rail, driving fixed frame 80 to move above positioning seat 30. It should be noted that since all mechanisms in this embodiment are set in two sets on frame 11, it ensures that the automated equipment can be integrated with the processing of injection molding machine 10, improving production efficiency and achieving stable gripping of workpiece under the action of suction cup.

[0063] Preferably, when using linear guides to move the adsorption plate 81, this can be accomplished by two mutually perpendicular and movably connected linear guide structures. This method is the same as the structure and principle used in conventional machinery, and will not be described in detail here. In addition, this embodiment also provides a conveyor belt 12 outside the frame 11 to facilitate the automatic unloading, stacking, and storage of qualified workpieces.

[0064] The adjusting plate 82 has a first oblong hole 820 and a second oblong hole 821 that are not interconnected. The first oblong hole 820 is used to adjust the installation position of the adjusting plate 82 relative to the fixing frame 80. The adsorption plate 81 is installed in the second oblong hole 821 and the position of the adsorption plate 81 in the second oblong hole 821 can be adjusted by tightening the locking nut 822.

[0065] Furthermore, such as Figure 8 As shown, the first oblong hole 820 and the second oblong hole 821 on the adjusting plate 82 are not connected. During the assembly process of the adjusting plate 82, the worker or robot can adjust the contact area between the adjusting plate 82 and the fixed frame 80 through the first oblong hole 820 to ensure that the adsorption plate 81 has sufficient distance to pick up the workpiece in the positioning seat 30. Similarly, under the action of the second oblong hole 821, the position of the adsorption plate 81 on the adjusting plate 82 can also be further adjusted. The adsorption plate 81 is provided with an external thread that mates with the locking nut. Therefore, when the adsorption plate 81 is in the required position, the adsorption plate 81 can be locked onto the adjusting plate 82 by the locking nut, effectively ensuring the stability of the adsorption plate 81 when transferring the workpiece. Preferably, this solution can also provide a cylinder gripper for gripping waste on the workpiece at the end of the adjusting plate 82 away from the fixed frame 80.

[0066] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0067] Furthermore, in this invention, descriptions involving terms such as "first," "second," and "a" are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0068] In this invention, unless otherwise explicitly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly.
