Positioning mechanism and transfer device

Abstract

The present invention relates to a positioning mechanism and a transfer device. A material pushing driving member drives a plurality of abutting members to approach a limit block, so that the material can be pushed to abut against the limit block, thereby realizing the clamping and positioning of the material. Moreover, each abutting member can elastically retract when abutting against the material in the clamping space, so that the plurality of abutting members can reliably abut against the edge of the material, thereby enabling the other side end of the material to reliably abut against the limit block, significantly improving the positioning accuracy. After the material is positioned on the adsorption table by the positioning mechanism, it does not need to be removed from the adsorption table. The flipping mechanism can drive the adsorption table to flip as a whole to a designated station. Then, the adsorption table is pressed down or the material on the designated station is moved up, so that the material on the adsorption table can be pressed against another material at the designated station. Since the material will not be displaced relative to the adsorption table before the bonding is completed, it is effectively avoided that the positioned material is deformed or offset again. Therefore, the bonding accuracy can be improved.

Description

Technical Field

[0001] The present invention relates to the field of mechanical automation technology, and in particular to a positioning mechanism and a transfer device. Background Art

[0002] In industrial production, such as battery assembly, the mounting of two materials is often involved. To achieve accurate mounting, the first thing to solve is the problem of accurate positioning. The traditional approach is to first use a positioning mechanism to position the materials to be bonded; after positioning, the materials are transferred to the preset station by a robot with a suction cup, and then mounted based on visual positioning.

[0003] Traditional positioning methods can achieve accurate placement for materials with short length and regular shape. However, with the continuous upgrading of products, placement will also involve ultra-thin and ultra-long special-shaped materials. In this case, traditional positioning methods will not be able to achieve accurate positioning, resulting in low placement accuracy. Summary of the invention

[0004] Based on this, it is necessary to provide a positioning mechanism and a transfer device that can improve the positioning accuracy in order to solve the above problems.

[0005] A positioning mechanism (100), comprising:

[0006] A limiting assembly (110), comprising a limiting block (111); and

[0007] A material pushing assembly (120), comprising a material pushing driving member (121) and a plurality of abutting members (122) drivingly connected to the material pushing driving member (121), wherein the plurality of abutting members (122) can cooperate with the limiting block (111) to form a long strip of clamping space, and the plurality of abutting members (122) can approach or move away from the limiting block (111) under the driving of the material pushing driving member (121) to clamp or loosen the material in the clamping space;

[0008] The plurality of abutting members (122) are arranged at intervals along the length direction of the clamping space, and each of the abutting members (122) can elastically retract when abutting against the material in the clamping space.

[0009] In one embodiment, the limiting assembly (110) further includes:

[0010] A first support (112), the limiting block (111) being slidably disposed on the first support (112) along a direction perpendicular to the length direction of the clamping space;

[0011] A limit driving member (113) is drivingly connected to the limit block (111) to drive the limit block (111) to slide along the first support (112).

[0012] In one embodiment, the limiting assembly (110) further comprises a first mounting plate (114), the first mounting plate (114) being slidably disposed on the first support (112) along a direction perpendicular to the length direction of the clamping space, and a plurality of limiting blocks (111) being fixed to the first mounting plate (114) at intervals along the length direction of the clamping space.

[0014] In one embodiment, the elastic member (124) is a compression spring, the abutting member (122) is a push pin, and the compression spring is sleeved on the push pin and abuts against the mounting seat (123).

[0015] The above-mentioned positioning mechanism first places the material to be positioned in the clamping space. Then, the push drive member drives the multiple abutting members to approach the limit block, so that the material can be pushed to abut against the limit block, thereby achieving the clamping and positioning of the material. Moreover, each abutting member can elastically retract when abutting against the material in the clamping space. Therefore, the distance between each abutting member and the limit block can be different, so that the multiple abutting members can reliably abut against the edge of the material, and then the other side end of the material can reliably abut against the limit block, which significantly improves the positioning accuracy.

[0016] A transfer device (10), comprising:

[0017] The positioning mechanism (100) as described above;

[0021] In one embodiment, the flipping mechanism (400) comprises:

[0022] A second support (410), wherein a rotating shaft (411) is provided on the second support (410);

[0023] A rotary drive member (420) is fixed to the second support (410), and an output shaft of the rotary drive member (420) is drivingly connected to the rotating shaft (411);

[0024] The rotating seat (430) is fixed to the rotating shaft (411), and the adsorption platform (200) is arranged on the rotating seat (430).

[0025] In one embodiment, it further comprises a clamping mechanism (300), the adsorption platform (200) is arranged at the movable end of the clamping mechanism (300), and can be extended and retracted along a preset clamping direction under the drive of the clamping mechanism (300), and the clamping mechanism (300) is arranged at the movable end of the flipping mechanism (400), and can be flipped under the drive of the flipping mechanism (400).

[0026] In one embodiment, the clamping mechanism (300) comprises:

[0027] A first movable plate (310) is slidably disposed at a movable end of the flip mechanism (400) along the pressing direction, and the adsorption platform (200) is disposed on the first movable plate (310);

[0028] The lifting drive assembly (320) is capable of driving the first movable plate (310) to slide along the movable end of the turning mechanism (400).

[0030] In one embodiment, the clamping mechanism (300) further includes a second movable plate (330) and a pressure sensor (340), wherein the second movable plate (330) is slidably disposed on the first movable plate (310) along the clamping direction, the adsorption platform (200) is installed on the second movable plate (330), and the pressure sensor (340) is clamped between the second movable plate (330) and the first movable plate (310).

[0031] In one embodiment, the pressing mechanism (300) further includes a spring (350), and the pressure sensor (340) and the second movable plate (330) are in contact with each other via the spring (350).

[0033] In the above-mentioned transfer device, after the material is positioned on the adsorption table by the positioning mechanism, there is no need to remove it from the adsorption table. The flipping mechanism can drive the adsorption table to flip over as a whole to the designated station. At this time, the material is facing downward. Then, the adsorption table is pressed down in the pressing direction or the material at the designated station is moved up in the pressing direction, so that the material on the adsorption table can be pressed against another material at the designated station to achieve bonding. Since the material is adsorbed on the adsorption table after positioning, the material will not be displaced relative to the adsorption table before bonding is completed, which effectively avoids deformation or displacement of the positioned material again. Therefore, the bonding accuracy of the above-mentioned transfer device can be improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0053] See also Figure 1 The present invention provides a transfer device 10 and a positioning mechanism 100. The transfer device 10 includes a positioning mechanism 100, an adsorption platform 200, a pressing mechanism 300 and a flipping mechanism 400.

[0054] The positioning mechanism 100 can form a long strip of clamping space, so that the long strip of material can be clamped and positioned. The adsorption table 200 is used to carry and adsorb the material. Moreover, the adsorption table 200 is located in the clamping space and is arranged along the length direction of the clamping space. The material can be placed on the adsorption table 200 first, and then clamped and positioned by the positioning mechanism 100. The adsorption table 200 is generally a block-shaped or plate-shaped structure formed of a metal material and has strong rigidity. Among them, the adsorption table 200 can be single and extend along the length direction of the clamping space, or it can be multiple and arranged at intervals along the length direction of the clamping space.

[0055] The upper surface of the adsorption platform 200 is flat, so it can be well attached to the surface of the material. Moreover, the adsorption platform 200 can adsorb the material in various ways such as electrostatic adsorption, vacuum adsorption, and magnetic adsorption. Specifically in this embodiment, adsorption holes (not shown) are provided on the adsorption platform 200. The adsorption holes can be connected to the exhaust device through a pipeline, and the exhaust device can form a negative pressure on the surface of the adsorption platform 200, so that the material can be vacuum adsorbed.

[0056] The adsorption platform 200 is arranged at the movable end of the clamping mechanism 300, and the clamping mechanism 300 can drive the adsorption platform 200 to extend and retract along the preset clamping direction. The clamping mechanism 300 is arranged at the movable end of the flipping mechanism 400, and the flipping mechanism 400 can drive the clamping mechanism 300 and the adsorption platform 200 on the clamping mechanism 300 to flip as a whole. Among them, the flipping angle of the flipping mechanism 400 can be 0 to 180 degrees, and the clamping direction is generally perpendicular to the extension direction of the flip axis of the flipping mechanism 400.

[0057] After the material is positioned on the adsorption table 200 by the positioning mechanism 100, it does not need to be removed from the adsorption table 200. The flipping mechanism 400 can drive the clamping mechanism 300 and the adsorption table 200 to flip as a whole to the designated station. Specifically, the adsorption table 200 is flipped 180 degrees. At this time, the adsorption table 200 is turned over so that the material faces downward. Then, the clamping mechanism 300 is activated and drives the adsorption table 200 to press down in the clamping direction (vertical direction at this time), so that the material on the adsorption table 200 can be pressed against another material at the designated station to achieve bonding.

[0058] Since the material is adsorbed on the adsorption table 200 after positioning and is not separated from the adsorption table 200 before mounting, the material will not be displaced relative to the adsorption table 200 before mounting, which effectively avoids deformation or displacement of the positioned material again, and the mounting accuracy of the transfer device 10 can be improved.

[0059] It should be noted that in other embodiments, the pressing mechanism 300 can be omitted, and the adsorption platform 200 is directly disposed at the movable end of the flip mechanism 400. When the flip mechanism 400 drives the adsorption platform 200 to flip as a whole to a designated station, the two materials can be bonded by moving the material on the designated station upward.

[0060] Please also read Fig.12 Specifically in this embodiment, the surface of the adsorption platform 200 for carrying materials is covered with an elastic cushion layer 210. The surface for carrying materials is generally the upper surface of the adsorption platform 200 in the initial state, and the elastic cushion layer 210 can be a silicone layer, a rubber layer, a foam layer or a sponge layer. When squeezed, the elastic cushion layer 210 can produce elastic deformation. In this way, when the adsorption platform 200 presses the material against the surface of another material at a designated station, the elastic cushion layer 210 can be deformed so that the two materials can fit better.

[0061] Please also read Figures 2 to 7 The positioning mechanism 100 in the preferred embodiment of the present invention includes a limiting component 110 and a pushing component 120 .

[0062] The limiting assembly 110 includes a limiting block 111. The pushing assembly 120 includes a pushing driving member 121 and a plurality of abutting members 122 which are transmission-connected to the pushing driving member 121. Among them, the plurality of abutting members 122 can cooperate with the limiting block 111 to form a long strip of clamping space. Specifically, the limiting assembly 110 and the pushing assembly 120 can be respectively arranged on opposite sides of the adsorption platform 200. The limiting block 111 can be a metal block or plate-like structure, and the abutting member 122 can also be a block or rod-like structure. The limiting block 111 can be a single one extending along the length direction of the clamping space, or a plurality of them can be arranged at intervals along the length direction of the clamping space.

[0063] Please refer again Figures 2 to 4 In this embodiment, the limiting assembly 110 further includes a first support 112 and a limiting driving member 113. The limiting block 111 is slidably disposed on the first support 112 along a direction perpendicular to the length direction of the clamping space. The limiting driving member 113 is transmission-connected to the limiting block 111 to drive the limiting block 111 to slide along the first support 112.

[0064] The first support 112 plays a supporting role and is generally a metal frame structure. Figure 1 As shown, the length direction of the clamping space is perpendicular to the plane direction of the drawing, and the limit block 111 can slide in the horizontal direction on the first support 112. The limit drive 113 can be a cylinder, a linear motor, etc. When positioning is required, the limit drive 113 can drive the limit block 111 to move to a set position as a reference for positioning. When positioning is not required, the limit drive 113 drives the limit block 111 away from the pusher assembly 120 to facilitate placing the material into the clamping space.

[0065] The first support 112 can be an integral structure with the frame of the material pushing assembly 120, or can be designed separately. Specifically in this embodiment, the first support 112 is separately arranged from the frame of the material pushing assembly 120. In this way, the position limiting assembly 110 and the material pushing assembly 120 are arranged in a distributed manner, which is helpful for installation and layout.

[0066] In this embodiment, the limiting assembly 110 also includes a first mounting plate 114, which is slidably disposed on the first support 112 along a direction perpendicular to the length direction of the clamping space, and a plurality of limiting blocks 111 are fixed to the first mounting plate 114 at intervals along the length direction of the clamping space.

[0067] The first mounting plate 114 can be installed with the first support 112 through a linear rail slider structure. The first mounting plate 114 can be in a long strip shape and extend along the length direction of the clamping space. The limit drive 113 is connected to the first mounting plate 114 in a transmission manner, and by driving the first mounting plate 114 to slide, the plurality of limit blocks 111 are driven to slide synchronously in a direction perpendicular to the length direction of the clamping space. In order to ensure the position accuracy of each limit block 111, each limit block 111 can be installed on a fixed linear rail (not shown in the figure). The fixed linear rail has high processing accuracy and good straightness, so it can ensure the straightness of each limit block 111.

[0068] Furthermore, the plurality of abutting members 122 can be driven by the material pushing driving member 121 to move closer to or farther from the stop block 111 to clamp or loosen the material in the clamping space. The material pushing driving member 121 can be a driving mechanism such as a cylinder or a linear motor. The plurality of abutting members 122 are arranged at intervals along the length direction of the clamping space, and each abutting member 122 can elastically retract when abutting against the material in the clamping space.

[0069] The push drive 121 drives the multiple abutting members 122 to approach the limit block 111, so that the material on the adsorption platform 200 can be pushed toward the limit block 111 until the material abuts against the limit block 111, thereby achieving the clamping and positioning of the material. Moreover, since each abutting member 122 can elastically retract when abutting against the material in the clamping space, even if the edge of the material is irregular, the multiple abutting members 122 can reliably abut against the edge of the material, and then the other side of the material can reliably abut against the limit block 111, significantly improving the positioning accuracy.

[0070] It should be noted that the abutting member 122 can be elastic itself, thereby realizing elastic retraction. In addition, the abutting member 122 can also be installed in an elastically connected manner, thus realizing elastic retraction as well.

[0071] Please refer again Figures 5 to 7 In this embodiment, the pushing assembly 120 also includes a mounting seat 123 and a plurality of elastic members 124. A plurality of resisting members 122 are slidably arranged on the mounting seat 123 along a direction perpendicular to the length direction of the clamping space. The pushing driving member 121 can drive the mounting seat 123 to move along a direction perpendicular to the length direction of the clamping space. The elastic member 124 provides a restoring force to the resisting member 122 when the resisting member 122 retracts relative to the mounting seat 123.

[0072] The mounting seat 123 is generally a long strip-shaped plate-like structure, and a plurality of abutting members 122 can be arranged at intervals along its length. The number of elastic members 124 is generally the same as the number of abutting members 122, and they are arranged one by one. The elastic member 124 can be an elastic energy storage structure such as a spring, a torsion spring, an elastic pad, an elastic rope, etc.

[0073] When the push drive member 121 drives the mounting seat 123 to move in a direction perpendicular to the length direction of the clamping space, it can drive the multiple abutting members 122 as a whole to approach or move away from the limit block 111. If the edge of the material in the clamping space is irregular, with protrusions and depressions, a part of the abutting members 122 will first abut against the protruding part of the material. At this time, if the mounting seat 123 is continued to be pushed, the part of the abutting members 122 can retract relative to the mounting seat 123 under the reaction of the material, and the corresponding elastic member 124 can generate a restoring force. The restoring force can make the part of the abutting members 122 press against the material. Moreover, since the abutting members 122 that first contact the material elastically retreat, it will not prevent the mounting seat 123 from continuing to approach the limit block 111 until the other abutting members 122 abut against the concave part of the edge of the material, so that the multiple abutting members 122 finally abut against the edge of the material.

[0074] Moreover, the mounting seat 111 can be slidably arranged on the frame of the material pushing assembly 120 through a linear rail slider structure. Therefore, the abutting member 122 approaches the limiting block 111 through translation and clamps the material. In this way, the clamping and positioning process can be made smoother.

[0075] It should be noted that, in other embodiments, the pusher assembly 120 may also use other methods to make the abutment member 122 approach or move away from the limit block 111, and realize the elastic retraction of the abutment member 122 by other corresponding methods. For example:

[0076] The abutment member 122 can rotate rather than translate under the drive of the push drive member 121, and can move closer to or farther from the stop block 111 by rotating. At this time, a torsion spring can be arranged between the abutment member 122 and the rotating shaft, and the elastic retraction of the abutment member 122 can be achieved by twisting the torsion spring. Alternatively, the abutment member 122 is a metal sheet with an abutment joint, which can achieve elastic retraction by its own elastic deformation.

[0077] Alternatively, the resisting member 122 may be driven by the pusher drive member 121 to translate, and the resisting member 122 is connected to the driving end of the pusher drive member 121 via an X-shaped connecting rod, and may also achieve elastic retraction.

[0078] Furthermore, in this embodiment, the elastic member 124 is a compression spring, the abutting member 122 is an ejector pin, and the compression spring is sleeved on the ejector pin and abuts against the mounting seat 123 .

[0079] The ejector pin is rod-shaped and generally extends in the translation direction of the abutment member 122, that is, in a direction perpendicular to the length direction of the clamping space. On the one hand, the ejector pin can provide a limit for the compression spring, facilitating the installation of the elastic member 124; on the other hand, the ejector pin has a small cross-section and a small contact area with the edge of the material, so that when there are sudden changes such as corners and steps on the edge of the material, it can still achieve reliable abutment with it.

[0080] Please also read Figures 8 to 10 In this embodiment, the flipping mechanism 400 includes a second support 410 , a rotation driving member 420 and a rotating base 430 .

[0081] The second support 410 plays a supporting role and is generally a metal frame structure. Among them, the second support 410 can be an integrated structure with the first support 112, and can also be used as a frame of the pusher assembly 120 or the frame of the entire transfer device 10. A rotatable shaft 411 is provided on the second support 410. The rotating drive member 420 is fixed to the second support 410, and the output shaft of the rotating drive member 420 is connected to the rotating shaft 411 in a transmission manner. The rotating drive member 420 can be a motor, a rotating cylinder, etc. The output shaft of the rotating drive member 420 can be connected to the rotating shaft 411 through a coupling, so the rotating drive member 420 can drive the rotating shaft 411 to rotate.

[0082] The rotating seat 430 is fixed to the rotating shaft 411, and the pressing mechanism 300 is disposed on the rotating seat 430. Therefore, when the rotating driving member 420 is started, the pressing mechanism 300 and the adsorption platform 200 can be turned over as a whole through the rotating seat 430.

[0083] Furthermore, in this embodiment, the pressing mechanism 300 includes a first moving plate 310 and a lifting drive assembly 320. Among them:

[0084] The first movable plate 310 is slidably disposed at the movable end of the flip mechanism 400, i.e., the rotating seat 430, along the pressing direction, and the adsorption platform 200 is disposed on the first movable plate 310. Specifically, a rotating plate 431 is disposed on one side of the rotating seat 430, and the first movable plate 310 can be slidably disposed on the rotating plate 431 together with the linear rail slider. The first movable plate 310 is in an elongated shape and extends along the length direction of the clamping space. In order to provide stable support for the first movable plate 310, the rotating seats 430 are generally multiple and are spaced apart along the extension direction of the first movable plate 310.

[0085] The lifting drive assembly 320 can drive the first movable plate 310 to slide along the movable end of the flip mechanism 400, that is, the rotating seat 430. The lifting drive assembly 320 can be fixedly mounted on the rotating plate 431, and its movable end is connected to the first movable plate 310. When the pressing mechanism 300 and the adsorption table 200 are flipped to the designated station as a whole, the lifting drive assembly 320 can drive the adsorption table 200 to press down by driving the first movable plate 310 to slide along the rotating seat 430, thereby pressing the material adsorbed on the adsorption table 200 onto another material at the designated station.

[0086] For further information, please also refer to Fig.11 In this embodiment, the lifting drive assembly 320 includes a power source 321, a plurality of action actuators 322 spaced apart along the length direction of the first movable plate 310, a belt 323, and a plurality of driven wheels 3221 corresponding to the plurality of action actuators 322.

[0087] The power source 321 includes a driving wheel 3211, and a plurality of driven wheels 3221 are driven by a belt 323 and the driving wheel 3211. The rotation of the driven wheel 3221 can drive the corresponding action actuator 322 to drive the first movable plate 310 to slide. The power source 321 is generally a motor for providing power. The action actuator 322 can be a power transmission structure such as a ball screw pair. The power of the power source 321 is transmitted to the plurality of action actuators 322 through the driving wheel 3221, the belt 323 and the plurality of driven wheels 3221, and the first movable plate 310 is driven by the plurality of action actuators 322.

[0088] Specifically, when the driven wheel 3221 rotates driven by the belt 323, it can drive the corresponding action actuator 322 and convert the rotation into linear motion. Therefore, the action actuator 322 can directly drive the first moving plate 310 to slide along the rotating seat 430 under the power output of the power source 321.

[0089] Thus, the lifting drive assembly 320 has multiple force application points on the first movable plate 310, so the first movable plate 310 is more balanced in force during the sliding process, and slides more smoothly, thereby making the pressing process more stable. In addition, only one power source 321 is provided, which can significantly reduce costs and simplify the structure.

[0090] Please refer again Figure 8 In this embodiment, the clamping mechanism 300 also includes a second movable plate 330 and a pressure sensor 340. The second movable plate 330 is slidably disposed on the first movable plate 310 along the clamping direction. The adsorption platform 200 is installed on the second movable plate 330. The pressure sensor 340 is disposed between the second movable plate 330 and the first movable plate 310.

[0091] Specifically, the second movable plate 330 can also be installed on the first movable plate 310 through the linear rail slider structure. When the lifting drive assembly 320 drives the first movable plate 310 to press down, and the adsorption platform 200 contacts the material at the designated station, the adsorption platform 200 will have a retreat tendency under the action of the reaction force, thereby squeezing the pressure sensor 340. At this time, the reading of the pressure sensor 340 can intuitively reflect the pressing force applied to the material.

[0092] Further, in the present embodiment, the clamping mechanism 300 further includes a spring 350, and the pressure sensor 340 is in contact with the second movable plate 330 through the spring 350. The spring 350 acts on the second movable plate 330, so that the second movable plate 330 has a tendency to extend. When the adsorption platform 200 is subjected to a reaction force, the second movable plate 330 will float within a certain range. In this way, a protective effect can be played. At the same time, the reading of the pressure sensor 340 can be made more accurate.

[0093] Furthermore, in the present embodiment, the clamping mechanism 300 also includes a connecting plate 360 ​​fixedly mounted on the first movable plate 310, the second movable plate 330 is slidably mounted on the connecting plate 360 ​​along the clamping direction, a blocking plate 361 is provided on the connecting plate 360, and a limiting plate 331 is provided on the second movable plate 330, and under the action of the spring 350, the limiting plate 331 abuts against the blocking plate 361.

[0094] The limiting plate 331 cooperates with the blocking plate 361 to limit the second movable plate 330. The connecting plate 360 ​​can be integrally formed with the first movable plate 310, or fixed to the first movable plate 330 by means of threaded fastening, welding, etc. The reason for setting the connecting plate 360 ​​instead of directly setting the second movable plate 330 on the first movable plate 310 is to facilitate processing. The length of the second movable plate 330 is smaller than that of the first movable plate 310, and multiple second movable plates 330 are arranged at intervals along the extension direction of the first movable plate 310. Correspondingly, the connecting plate 360 ​​is also multiple and is arranged at intervals along the extension direction of the first movable plate 310. In this way, a more balanced support can be provided for the adsorption platform 200.

[0095] Specifically in this embodiment, the clamping mechanism 300 further includes a second mounting plate 370 , a plurality of adsorption platforms 200 are arranged on the second mounting plate 370 at intervals along the length direction of the clamping space, and the second mounting plate 370 is fixed to the second movable plate 330 .

[0096] The second mounting plate 370 is generally in the shape of an elongated strip, and the plurality of adsorption platforms 200 can be turned over and pressed down synchronously under the drive of the second mounting plate 370 .

[0097] The above-mentioned transfer device 10 and positioning mechanism 100 first place the material to be positioned in the clamping space. Then, the material pushing drive member 121 drives the multiple abutting members 122 to approach the limit block 111, and the material can be pushed to abut against the limit block 111, thereby achieving the clamping and positioning of the material. Moreover, each abutting member 122 can elastically retract when abutting against the material in the clamping space. Therefore, the distance between each abutting member 122 and the limit block 111 can be different, so that the multiple abutting members 122 can reliably abut against the edge of the material, and then the other side end of the material can reliably abut against the limit block 111, which significantly improves the positioning accuracy.

[0098] Furthermore, after the material is positioned on the adsorption table 200 by the positioning mechanism 100, it does not need to be removed from the adsorption table 200. The flipping mechanism 400 can drive the clamping mechanism 300 and the adsorption table 200 to flip as a whole to the designated station. At this time, the material is facing downward. Then, the clamping mechanism 300 operates and drives the adsorption table 200 to press down in the clamping direction, so that the material on the adsorption table 200 can be pressed against another material at the designated station to achieve bonding. Since the material is adsorbed on the adsorption table 200 after positioning, the material will not be displaced relative to the adsorption table 200 before bonding is completed, which effectively avoids deformation or displacement of the positioned material again. Therefore, the bonding accuracy of the above-mentioned transfer device 10 can be improved.

[0099] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0100] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
