Description

Technical Field

[0002] Inkjet printing technology has broad application prospects in many manufacturing fields such as information, energy, medical, and national defense, and is increasingly applied to flexible device fields such as OLED, RFID, thin-film solar cells, wearable flexible devices, PCB, and smart skins. As one of the key technologies in the field of high-precision industrial manufacturing and printing, the performance of the core component, the print head module, directly affects the printing quality and equipment efficiency. In actual applications, the print head module needs to be maintained or replaced regularly to ensure the printing effect.

[0003] Currently, the replacement of the print head module of an inkjet printing device mainly relies on manual operation.

However, due to the characteristics that the print head module usually has a complex structure, the print head is relatively fragile, the cost is high, and sufficient position accuracy is required during installation, it is very time-consuming and laborious for technicians to install the print head module manually. Therefore, research and development on automatic installation and disassembly technology of the print head module is being carried out in the field to solve the problems existing in the above-mentioned manual operation and improve the replacement efficiency of the print head module.

[0051] In order to enable those skilled in the art of the present technology to better understand the solution of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present application.

[0052] The embodiment of the present application provides a transfer system for automatic loading of a nozzle module and an inkjet printing device. The key inventive point lies in that through the first positioning surface and the second positioning surface, an operator can quickly complete the preliminary positioning and placement of the nozzle module on the transfer seat, and under the driving action of the first limiting component and the second limiting component, the nozzle module is further pressed against the first positioning surface and the second positioning surface for positioning. Finally, it is ensured that the nozzle module is safe and stable during the process of being transported to the next installation node by the conveying device, and the position accuracy of the nozzle module when it is transported to the next installation node is improved, thereby ensuring the smooth execution of the automatic installation of the nozzle module.

[0053] In the first aspect, referring to Figure 1 , the present application provides a transfer system for automatic loading, which includes a transfer seat 1, a first limiting component 2, a second limiting component 3, and a conveying device 4.

[0054] Among them, the transfer seat 1 is used to carry the nozzle module 5 that needs to be automatically installed. And in order to facilitate the quick positioning and placement of the nozzle module 5 thereon, the transfer seat 1 is provided with a first positioning surface 111 perpendicular to the first direction and a second positioning surface 112 perpendicular to the second direction. Herein, the first direction and the second direction are mutually perpendicular horizontal directions. Furthermore, the first positioning surface 111 and the second positioning surface 112 are both vertically arranged and perpendicular to each other. For the convenience of understanding, the first direction, the second direction, and the vertical direction described in the present application can specifically refer to the three-dimensional coordinate axes in the figure, where the X direction corresponds to the first direction, the Y direction corresponds to the second direction, and the Z direction corresponds to the vertical direction.

[0055] The first limiting component 2 includes a first pushing end 21 movably arranged in the first direction and a first driving member for driving the first pushing end 21 to move, which is used to push the nozzle module 5 in the first direction to press against the first positioning surface 111; the second limiting component 3 includes a second pushing end 31 movably arranged in the second direction and a second driving member for driving the second pushing end 31 to move, which is used to push the nozzle module 5 in the second direction to press against the second positioning surface 112.

[0056] The conveying device 4 is used for connecting the transfer seat and for conveying the transfer seat 1 and the nozzle module 5 thereon, so that it can move along a preset trajectory to the next installation node.

[0057] Furthermore, referring to Figure 2, in some embodiments, the transfer base 1 includes a transfer table 10 and a carrying tooling 11. Among them, the transfer base 1 is connected to the conveying device 4, and the carrying tooling 11 is detachably and fixedly connected to the transfer table 10, enabling the carrying tooling 11 to be separated from the transfer table 10. At the same time, a carrying groove 110 for receiving the carrying nozzle module 5 is provided on the top surface of the carrying tooling 11, and the carrying space in the carrying groove 110 is adapted and overall larger than the cuboid structure of the nozzle module 5. Furthermore, through the carrying tooling 11, the operator can first place the nozzle module 5 in the carrying tooling 11, and then place it on the transfer base 1 together with the carrying tooling 11, ensuring that the feeding process of the nozzle module 5 is safer and more reliable, and avoiding accidental contact of the operator with the relevant precision structures on the nozzle module 5. On the other hand, the first positioning surface 111 is provided on one vertical side wall of the carrying groove 110 perpendicular to the first direction, and the second positioning surface 112 is provided on one side wall of the carrying groove 110 perpendicular to the second direction, enabling the operator to pre-position the nozzle module 5 placed therein based on the side walls of the carrying groove 110.

[0058] In addition, since the space of the carrying groove 110 is larger than that of the nozzle module 5 and the top is open, due to the relatively high center of gravity of the nozzle module 5, the nozzle module 5 may still move in the horizontal and vertical directions therein, and may even topple over. To further ensure the safety and stability of the carrying tooling 11 during manual transfer together with the nozzle module 5, a protective limiting component 12 is also provided in the carrying groove 110. The protective limiting component 12 will be used to limit the movement of the nozzle module 5 in the vertical direction, thereby preventing the nozzle module 5 from toppling over.

[0059] Furthermore, in this embodiment, referring to Figure 3 and Figure 4 , the protective limiting component 12 includes:

[0060] A protective elastic body 120, which is provided on the side wall of the carrying groove 110 perpendicular to the first direction and elastically expands and contracts in the first direction;

[0061] A protective locking tongue 121, which is movably arranged in the first direction. One end of it is connected to the protective elastic body 120, and the other end extends into the carrying groove 110, and the end portion includes a transmission inclined surface 1210 at the top and a limiting plane 1211 at the bottom.

[0062] Specifically, two protective elastic bodies 120 are respectively installed on the inner walls of both sides of the bearing groove 110 perpendicular to the first direction, and the installation heights of the protective elastic bodies 120 on the two side walls are the same. Each protective elastic body 120 is correspondingly connected to a protective locking tongue 121. The upper edge of the end of the protective locking tongue 121 away from the protective elastic body 120 is provided with a transmission inclined surface 1210 which is an upper inclined surface, and the bottom edge is provided with a limiting plane 1211 which is a plane. Among them, the top of the transmission inclined surface 1210 extends vertically to the same height as the notch of the bearing groove 110, so that when the nozzle module 5 is placed in the bearing groove 110, it can contact the transmission inclined surface 1210 for the first time and press the protective locking tongue 121 back in the first direction.

[0063] In addition, a mating groove 50 for mating with the protective locking tongue 121 is also provided on the vertical side wall of the nozzle module 5 perpendicular to the first direction, so that after the nozzle module 5 is placed in the bearing groove 110, the protective locking tongue 121 can be elastically inserted into the bearing groove 110 under the action of the protective elastic body 120, and the vertical limit of the nozzle module 5 is realized through the cooperation between the limiting plane 1211 and the side wall of the bearing groove 110. It should be noted that in order to ensure that the protective locking tongue 121 can be smoothly inserted into the mating groove 50 to realize the vertical limit of the nozzle module 5, the elastic movement stroke of the protective locking tongue 121 in the bearing groove 110 needs to be greater than the first dimension allowance S1 when the nozzle module 5 moves in the bearing groove 110 in the first direction. Refer to Figure 6 . Specifically, the first dimension allowance S1 refers to the difference between the distance between the two opposite side walls in the first direction in the bearing groove 110 and the dimension required by the nozzle module 5 in the first direction when it is placed in the bearing groove 110. That is, after the nozzle module 5 is placed in the bearing groove 110, the maximum distance that it can theoretically move in this direction; similarly, the maximum distance that the nozzle module 5 can move in the second direction in the bearing groove 110 is the second dimension allowance S2.

[0064] In this embodiment, refer to Figure 4 And Figure 5 , the protective limit component 12 further includes a moving shaft 122. The moving shaft 122 is slidably installed in the bearing tooling 11 along the first direction, and the end extending into the bearing groove 110 is connected to the protective locking tongue 121;

[0065] Meanwhile, installation cavities 113 are formed inside the two side walls of the bearing groove 110 perpendicular to the first direction. The installation cavities 113 extend in the first direction, and openings are formed on the side walls of the bearing groove 110 and on the top surface of the bearing tooling 11, so as to facilitate the end of the protection lock tongue 121 to extend into the bearing groove 110, and to ensure that the top edge of the transmission inclined surface 1210 of the protection lock tongue 121 is flush with the opening of the bearing groove 110. The moving shaft 122 is slidably installed in the installation cavity 113 in the first direction and has a limited movement stroke. When the moving shaft 122 moves to both ends of the movement stroke, the whole protection lock tongue 121 will be retracted into the installation cavity 113 respectively, and the protection lock tongue 121 will extend into the bearing groove 110 to the greatest extent.

[0066] Both ends of the protection elastic body 120 are respectively abutted against the protection lock tongue 121 and the bearing tooling 11, so that the moving shaft 122 always has a tendency to pop outwards. Furthermore, when the protection lock tongue 121 is aligned with the mating groove 50, it can ensure that the protection lock tongue 121 quickly pops into the mating groove 50 in time, providing movement restriction for the nozzle module 5. In this embodiment, the protection elastic body 120 is a compression spring with an axial compression direction in the first direction, and it is sleeved outside the moving shaft 122. In other embodiments, the protection elastic body 120 can also be other structural objects with compression and reset capabilities, such as compressed air bags, silicone rubber, polyurethane, etc.

[0067] Meanwhile, the upward inclined surface setting of the transmission inclined surface 1210 at the end of the protection lock tongue 121 will also make the downward pressure required for the nozzle module 5 to press back the protection lock tongue 121 through inclined surface cooperation a linear function form. In other embodiments, the transmission inclined surface 1210 at the end of the protection lock tongue 121 can adopt an upward curved surface structure. For the protection lock tongue 121 with an upward curved surface setting, although it can also drive the protection lock tongue 121 after inclined surface cooperation, in this process, as the bottom edge of the nozzle module 5 gradually descends at the contact position on the curved surface, the downward pressure that needs to be increased per unit distance of the downward pressure of the nozzle module 5 gradually decreases. Therefore, the downward pressure required for the nozzle module 5 to press back the protection lock tongue 121 in the whole process is a curvilinear function form. For operators, these two forms, the linear function form of the force application process is more in line with human needs. Therefore, the upward inclined surface setting of the protection lock tongue 121 in this embodiment will be beneficial for the operator to place the nozzle module 5 more smoothly into the bearing groove 110.

[0068] In addition, it should be noted that since the protective locking tongue 121 also needs to extend into the mating groove 50 when the nozzle module 5 abuts against the first positioning surface 111 to achieve vertical limitation of the nozzle module 5, the compression stroke of the protective locking tongue 121 during its transmission cooperation with the nozzle module 5 is relatively long, specifically including the first dimensional allowance S1 and the distance that the protective locking tongue 121 extends into the mating groove 50. Therefore, in order to reduce the resistance of the operator during the placement of the nozzle module 5, it is necessary to ensure that the protective elastic body 120 has a relatively small elastic coefficient, and the elastic coefficient will be specifically determined according to whether it is difficult for the operator to place the nozzle module 5. No further explanation is provided in this application.

[0069] Furthermore, in some embodiments, in order to facilitate the operator to quickly and smoothly complete the feeding operation of the nozzle module 5, the dimensional allowance of the wall spacing of the carrying groove 110 in one direction is greater than that in the other direction. Specifically, referring to Figure 6 , in this embodiment, the wall spacing of the carrying groove 110 in the second direction corresponding to the first dimensional allowance S1 of the nozzle module 5 will be greater than the wall spacing of the carrying groove 110 in the second direction corresponding to the second dimensional allowance S2 of the nozzle module 5. Furthermore, when the operator places the nozzle module 5, the operator can conveniently place the entire nozzle module 5 within the carrying range of the carrying groove 110 in the second direction, and then only needs to pay attention to whether the nozzle module 5 is within the carrying range of the carrying groove 110 in the first direction.

[0070] Furthermore, in some embodiments, referring to Figure 2 , the first driving member includes a driving elastic body, the driving elastic body is disposed on the side wall of the carrying groove 110 perpendicular to the first direction and faces the first positioning surface 111, and the driving elastic body elastically expands and contracts in the first direction. The first pushing end 21 is connected to the end of the driving elastic body and can move in the first direction following the elastic expansion and contraction of the driving elastic body, and the elastic movement stroke of the first pushing end 21 extends into the carrying groove 110. At the same time, in order to ensure that the first pushing end 21 can smoothly push and cooperate with the nozzle module 5 during the dropping process, the end surface of the first pushing end 21 extending into the carrying groove 110 is provided with a transmission guiding surface, such as a curved surface or an inclined surface.

[0071] The second driving member includes an actively controlled driving member disposed on one side of the carrying tooling 11, and the second pushing end 31 is connected to the output end of the second driving member.

[0072] With such a setting, during the placement of the nozzle module 5, the nozzle module 5 will form an inclined surface drive with the transmission guide surface at the end of the first thrust end 21, thereby compressing the driving elastic body, causing the first thrust end 21 to gradually withdraw from the bearing groove 110. Until the entire first thrust end 21 is on one side of the nozzle module 5, the nozzle module 5 can be directly placed in the bearing groove 110. Subsequently, the first thrust end 21 will push the nozzle module 5 in the first direction based on the elastic force of the driving elastic body until the nozzle module 5 moves and abuts against the first positioning surface 111. It realizes the automatic positioning of the nozzle module 5 in the first direction when it is placed in the bearing groove 11, and also makes it unnecessary to set an active control structure on the transfer table 10 to control the push in the first direction, effectively reducing the space occupation on the transfer table 10 and reducing the equipment cost.

[0073] It should be noted that, due to the relatively small first dimension margin S1 in the first direction, the pushing distance of the driving elastic body in the first direction is relatively smaller. Then, the elastic force that the operator needs to overcome when placing the nozzle module 5 is also relatively smaller, enabling the operator to smoothly place the nozzle module 5 in the bearing groove 110. For the second direction, since the second dimension margin S2 is larger, if the driving and positioning of the nozzle module 5 is also performed by elastic driving in the second direction, the elastic force that the operator needs to overcome in the second direction when placing the nozzle module 5 is relatively larger than that in the first direction, which is not conducive to the manual placement of the nozzle module 5.

[0074] Therefore, in this application, the first limiting component 2 is selected to be arranged on the inner wall of the bearing groove 110 perpendicular to the first direction. In the second direction, in this embodiment, an active control type driving member outside the bearing groove is used as the second driving member, such as a cylinder, an electric telescopic rod, etc., to realize the control drive of the second thrust end 31 in the second direction, and finally tighten and position the nozzle module 5. At the same time, in this embodiment, the second driving member specifically uses a driving cylinder, which can have a certain buffer margin while driving the second thrust end 31 to move, avoiding hard extrusion and damaging the nozzle module 5 after the second thrust end 31 tightens the nozzle module 5 against the second positioning surface 112.

[0075] Further, referring to Figure 7 , in some embodiments, in order to further reduce the resistance that the operator encounters when placing the nozzle module 5 into the bearing groove 110, the first thrust end 21 is a ball head end that rolls on the end of the driving elastic body and is used to form a rolling fit when contacting the nozzle module 5. Specifically, the driving elastic body and the first thrust end 21 are specifically a ball plunger installed on the inner wall of the bearing groove 110 in this embodiment, and the first thrust end 21 is the rolling ball head that rolls on the end of the ball plunger.

[0076] It should be noted that the rolling ball head of the ball head plunger, that is, the first pushing end 21, extends into the bearing groove 110 by a distance less than its rotation radius. As a result, the bottom edge on the circumferential side of the nozzle module 5 can always be squeezed against the contact head during the placement process, and the first pushing end 21 is pressed out of the bearing groove 110.

[0077] When the rolling ball head serves as the first pushing end 21, even if there is an error between the elastic movement direction of the first pushing end 21 and the first direction, especially when the elastic movement direction is tilted upward relative to the first direction, the first pushing end 21 will move relative to the side wall of the nozzle module 5 in a rolling manner in the vertically upward direction during the process of the contact head driving the nozzle module 5 to move. At this time, the friction force between the two is very small, so it is not sufficient to generate the effect of driving the side of the nozzle module 5 upward. That is, it will not cause the nozzle module 5 to flip upward while driving the nozzle module 5 to move in the first direction, thus affecting the positioning of the nozzle module 5. For a non-rolling first pushing end 21, due to the sliding friction when the first pushing end 21 is in sliding fit with the side wall of the nozzle module 5, when there is a component force in the vertical direction between the first pushing end 21 and the side wall of the nozzle module 5, there is a possibility of driving the nozzle module 5 upward and causing the nozzle module 5 to flip by a certain angle, ultimately affecting the subsequent automatic installation process of the nozzle module 5.

[0078] Further, referring to Figure 8 , in some embodiments, the end face of the second pushing member is provided with a lower inclined surface and corresponds to the mating upper inclined surface 51 provided on the side wall of the nozzle module 5. Further, when the second pushing end 31 moves to contact the mating upper inclined surface 51 on the nozzle module 5 under the drive of the second driving member, the two will form an inclined surface fit. With the further drive of the second driving member, the second pushing end 31 forms a downward pressure and a driving force in the second direction on the nozzle module 5, and finally presses the nozzle module 5 against the second positioning surface 112 while effectively pressing and attaching the nozzle module 5, further ensuring the stability of the nozzle module 5 during transportation and the position accuracy in the vertical direction.

[0079] Furthermore, based on the above solution, it is necessary to install the protective limit component 12 on the side wall of the bearing groove 110 perpendicular to the first direction. Therefore, corresponding installation spaces and related installation structures need to be reserved inside the side wall, which will lead to a relatively high complexity of the two side walls of the bearing groove 110 in the first direction. Finally, due to the relatively high complexity of the two side walls of the bearing groove 110 in the first direction, there may be errors in the perpendicularity of the two side walls to the first direction during processing. And since the bearing groove 110 ultimately needs to accurately position the nozzle module 5 in the first direction, under this positioning requirement, if the side wall of the above-mentioned bearing groove 110 directly undertakes the function of resisting and positioning one side of the nozzle module 5, the accuracy of the first positioning surface 111 cannot be guaranteed.

[0080] To solve the above problems, further, referring to Figure 2 , in some embodiments, the carrying tooling 11 further includes:

[0081] At least two reference abutting portions 1110, which are fixedly arranged on the side wall of the carrying groove 110 facing the first pushing end 21. Each of them includes a reference end extending into the carrying groove 110, and the fixed position of the reference end in the first direction is adjustable, so that after the plurality of reference ends are in the same position in the first direction, a first positioning surface 111 can be formed.

[0082] In this embodiment, a total of four reference abutting portions 1110 are provided on the side wall of the carrying groove 110. The reference end of the reference abutting portion 1110 is a spherical end, and after the reference ends are installed on the side wall of the carrying groove 110 in the first direction, they are adjusted to the same position in the first direction, so as to jointly construct the first positioning surface 111 at multiple points. In other embodiments, the end face of the reference end can also be a planar structure or a conical structure with a small area that can ensure flatness. The present application does not limit this here.

[0083] Meanwhile, the position of the reference end at the end of the reference abutting portion 1110 in the first direction is adjustable, and different technical solutions can be adopted in different embodiments. For example, in some embodiments, the connection position of the reference end on the reference abutting portion 1110 is adjustable. In other embodiments, the reference end is fixed to the reference abutting portion 1110, and the installation position of the reference abutting portion 1110 is adjustable. The present application does not limit this. In this embodiment, the reference end is fixedly arranged at the end of the reference abutting portion 1110, and the installation position of the reference abutting portion 1110 on the carrying tooling 11 can be adjusted.

[0084] Specifically, referring to Figure 2 , to realize the adjustable position of the reference portion of the reference abutting portion 1110 in the first direction, in this embodiment, a movable shaft hole 1100 for installing the reference abutting portion 1110 is formed on the inner wall of the carrying groove 110. Both ends of the movable shaft hole 1100 are open and extend along the first direction, and the reference abutting portion 1110 is slidably fitted in the movable shaft hole 1100;

[0085] Referring to Figure 8 and Figure 9, a plurality of adjusting shaft holes 13 corresponding to the movable shaft holes 1100 one by one are vertically formed in the upper edge of the carrying tooling 11; one end of the adjusting shaft hole 13 communicates with the movable shaft hole 1100, and the other end extends to the surface of the carrying tooling 11 to form an opening. An axially adjustable locking screw 1101 is in threaded fit in the adjusting shaft hole 13, so as to fix the position of the reference abutting portion 1110 by controlling the end of the locking screw 1101 to move to abut against the reference abutting portion 1110 in the movable shaft hole 1100. After the locking screw 1101 is rotated to move away from the reference abutting portion 1110, the position of the reference abutting portion 1110 can be adjusted in the first direction.

[0086] Further, referring to Figure 2 , in some embodiments, a positioning stop bar 1120 is provided on the side wall of the carrying groove 110 facing the second pushing end 31. The surface of the positioning stop bar 1120 facing the second pushing end 31 is perpendicular to the second horizontal direction, forming a second positioning surface 112 capable of resisting and positioning the nozzle module 5.

[0087] Furthermore, in some embodiments, since the nozzle module 5 needs to be separated from the carrying tooling 11 during subsequent automatic installation, and the first limiting component 2 has a rolling contact with the nozzle module 5, in practice, it does not affect the vertical movement and separation of the nozzle module 5 relative to the carrying tooling 11. However, the protective locking tongue 121 is inserted into the mating groove 50, restricting the vertical movement of the nozzle module 5. Therefore, it is necessary to control the protective locking tongue 121 to withdraw in a timely manner in this case. For this purpose, referring to Figure 5 , in such embodiments, at least one unlocking driving part 6 is further provided on the transfer table 10 of the present application. The unlocking driving part 6 is located on one side of the carrying tooling 11 and includes an unlockable end 60 that can be controlled to move. A transmission rod 61 for linking the two is provided between the unlockable end 60 and the protective locking tongue 121. The transmission rod 61 is movably arranged in the carrying tooling 11 and one end extends outside the carrying tooling 11 to receive the movement amount of the unlockable end 60 and drive the protective locking tongue 121 to withdraw from the mating groove 50;

[0088] Specifically, in this embodiment, the protective limiting component 12 is provided on both inner walls of the carrying groove 110 perpendicular to the first direction. Therefore, transmission rods 61 lower than the protective locking tongue 121 are provided on both sides of the carrying tooling 11, and the transmission rods 61 are movably arranged along the second horizontal direction. One end of the transmission rod 61 extends outside the carrying tooling 11 for subsequent docking with the unlockable end 60 that performs driving. At the same time, in order to realize the linkage between the transmission rod 61 and the protective locking tongue 121, pushing blocks 610 corresponding to the number and spacing of the protective locking tongues 121 on the single-side inner wall are provided on the transmission rod 61.

[0089] Meanwhile, a transmission block 1220 is fixedly connected to the bottom of the moving shaft 122 connected to the protection lock tongue 121. The transmission block 1220 extends vertically downward, and there is an overlapping area in the vertical direction with the pushing block 610 on the lower transmission rod 61. The transmission block 1220 contacts the pushing block 610 in the second direction. At the same time, in order to enable the transmission block 1220 and the pushing block 610 to transmit in the second direction, the contact surfaces between the transmission block 1220 and the pushing block 610 are mutually matching contact inclined surfaces, so that when the two move relative to each other in the second horizontal direction, they can form an inclined surface type transmission fit. Furthermore, during the movement of the transmission rod 61 in the second horizontal direction, it is realized to drive the protection lock tongue 121 and the moving shaft 122 to move in the first direction, and further drive the protection lock tongue 121 to withdraw from the bearing groove 110.

[0090] Referring to Figure 5 , the unlocking drive part 6 is located on the transfer table 10 on one side of the bearing tooling 11, and includes an unlocking cylinder. The unlocking end 60 is a follower block 600 connected to the output shaft of the unlocking cylinder. The driving direction of the output shaft of the unlocking cylinder is the second horizontal direction. Therefore, after it is started, it can drive the follower block 600 to move in the second horizontal direction. One end of the follower block 600 in the second horizontal direction has a follower surface 601 perpendicular to the second horizontal direction, and the follower surface 601 extends in the first direction, so that it can synchronously contact the two transmission rods 61 located on both sides of the bearing groove 110 respectively. Furthermore, after the follower block 600 moves in the second horizontal direction to contact the ends of the two transmission rods 61, it can synchronously drive the transmission rods 61 to continue to move in the second horizontal direction, thereby synchronously driving the protection lock tongues 121 on the side walls of both sides of the bearing groove 110 to withdraw from the bearing groove 110.

[0091] Furthermore, in some embodiments, referring to Figure 10 , in order to realize the detachable connection of the bearing tooling 11 on the transfer table 10, the transfer seat 1 further includes a docking column 100. The docking column 100 is arranged vertically on the transfer table 10, and at least one radially elastically telescopic clamping steel ball 101 is arranged on the circumferential side wall of the docking column 100; at the same time, a docking sleeve for plugging and matching with the docking column 100 is arranged on the bottom surface of the bearing tooling 11, and docking holes corresponding to the clamping steel balls 101 are arranged on the inner wall of the docking sleeve.

[0092] Specifically, in this embodiment, two docking columns 100 are arranged at intervals on the transfer table 10. The docking columns 100 are in a cylindrical structure, and the circumferential edge of the top surface is chamfered, so that the docking sleeve on the bearing tooling 11 can be aligned with the docking column 100 more quickly. Four clamping steel balls 101 are arranged at equal angular intervals on the circumferential side wall of the docking column 100, and the four clamping steel balls 101 are at the same height. Correspondingly, two docking sleeves are embedded in the bottom surface of the bearing tooling 11, and four docking holes are opened on the circumferential side wall of the inner side of the docking sleeve.

[0093] Furthermore, when the operator places the carrying tooling 11 on the transfer table 10, it is only necessary to align the docking sleeve on the carrying tooling 11 with the docking column 100, and then insert the docking column 100 into the docking sleeve to place it on the transfer table 10. The detachable installation of the carrying tooling 11 on the transfer table 10 can be quickly achieved by the clamping fit between the clamping steel balls 101 and the docking holes. When it is necessary to remove the carrying tooling 11 from the transfer table 10 subsequently, the carrying tooling 11 can also be directly lifted vertically. After the clamping steel balls 101 are pressed back by the edge of the docking hole, the limit between the two can be released.
