[0033] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of this application. Apparently, the described embodiments are only a part rather than all of the embodiments of this application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of this application without making creative efforts shall fall within the scope of protection of this application.

[0034] The following disclosure provides many different embodiments or examples for implementing different structures of this application. To simplify the disclosure of this application, the components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit this application. In addition, this application may repeat reference numerals and / or letters in different examples. This repetition is for the purpose of simplification and clarity and does not in itself indicate the relationship between the various embodiments and / or settings discussed. In addition, this application provides examples of various specific processes and materials, but those of ordinary skill in the art can be aware of the applicability of other processes and / or the use of other materials.

[0035] For ease of description, spatial relative relationship terms may be used in the text to describe the relative position relationship or movement of one element or feature shown in the figure relative to another element or feature. These relative relationship terms such as "inside", "outside", "inner side", "outer side", "below", "beneath", "above", "upper", "front", "rear", etc. This spatial relative relationship term is intended to include different orientations of the device in use or operation other than the orientation depicted in the figure. For example, if the device in the figure undergoes a position flip, attitude change, or motion state change, then these directional indications will change accordingly. For example, an element described as "below other elements or features" or "beneath other elements or features" will subsequently be oriented as "above other elements or features" or "on other elements or features". Therefore, the exemplary term "below" can include both upper and lower orientations. The device may be oriented otherwise (rotated 90 degrees or in other directions) and the spatial relative relationship descriptors used in the text are interpreted accordingly.

[0036] See Figures 1 to 3, an embodiment of the present application provides a transfer fixture, including: a body 100 having a working surface 101; a first fixing portion 200 including a first abutting surface 210, a first limiting edge 220 surrounding the periphery of the first abutting surface 210, and a plurality of first vacuum holes 230. The side of the first limiting edge 220 away from the first abutting surface 210 is connected to the working surface 101 to form a first avoidance distance between the first abutting surface 210 and the working surface 101. The plurality of first vacuum holes 230 are spaced apart and distributed on the periphery of the first fixing portion 200; and a first vacuum channel 300 is provided in the body 100 and communicates with the first vacuum holes 230.

[0037] In this embodiment, the workpiece 1 to be transferred is placed on the transfer fixture 20. At this time, the lens group of the workpiece 1 to be transferred corresponds to the first fixing portion 200, and the bracket group surrounding the periphery of the lens group corresponds to the working surface 101 on the periphery of the first fixing portion 200. There is a first avoidance distance between the first abutting surface 210 and the working surface 101. On the one hand, while realizing the vacuum adsorption of the workpiece 1 to be transferred, it is possible to avoid the situation that the workpiece 1 to be transferred is scratched due to the presence of foreign objects on the first abutting surface 210, thereby improving the packaging yield. On the other hand, it is possible to provide a packaging error or assembly error space for the lens group of the workpiece 1 to be transferred to protrude downward along the first direction Z from the bracket group, thereby increasing the applicable range of the transfer fixture 20. At the same time, the vacuum device is connected to the plurality of first vacuum holes 230 through the first vacuum channel 300 to provide adsorption force for the plurality of vacuum holes; the plurality of vacuum holes are distributed on the periphery of the first fixing portion 200, and multi-point adsorption can be realized on the periphery of the lens group of the workpiece 1 to be transferred, improving the adsorption fastening between the workpiece 1 to be transferred and the transfer fixture 20, facilitating the precise grasping and transfer of the subsequent gripper, and improving the packaging accuracy and packaging quality of the workpiece 1 to be transferred.

[0038] Specifically, the transfer jig 20 is configured as a combined component including at least the body 100, the first fixing part 200, and the first vacuum channel 300. The body 100 can be a nearly rectangular base, which can be detachably connected to a moving mechanism such as a manipulator or a slider through fasteners such as screws / bolts, so as to realize the position transfer of the transfer jig 20, enabling it to act on multiple scenarios that need to carry intermediate packages, and improving the flexibility and application range of the transfer jig 20. The first fixing part 200 can be a nearly rectangular groove structure, which is arranged on the working surface 101 of the body 100 and recessed into the interior of the body 100 for realizing incoming material transfer. The first fixing part 200 is configured as a combined component including at least the first abutting surface 210, the first limiting edge 220, and a plurality of first vacuum holes 230. The first abutting surface 210 can be a plane, which is arranged below the working surface 101 and has a first avoidance distance from the working surface 101. This first avoidance distance can allow foreign objects to exist on the first abutting surface 210 and prevent scratching the bottom of the workpiece 1 to be transferred during vacuum adsorption; moreover, this first avoidance distance can also allow a certain packaging error or assembly error between the lens group and the bracket group of the workpiece 1 to be transferred, as long as the distance that the lens group protrudes downward from the bracket group is less than the first avoidance distance. The first limiting edge 220 can be a lateral skirt enclosing a nearly rectangle, with its bottom end arranged on the periphery of the first abutting surface 210 and its top end arranged on the working surface 101; the first limiting edge 220 can not only provide the first avoidance distance but also surround the periphery of the lens group of the workpiece 1 to be transferred, realizing the limiting of the workpiece 1 to be transferred, improving the position accuracy of the workpiece 1 to be transferred, facilitating subsequent accurate transfer and packaging, and improving the packaging accuracy and packaging effect of the product. The first vacuum hole 230 can be a circular hole. In the top view direction of the working surface 101, the first partial semi-circular hole wall of the first vacuum hole 230 can form the first limiting edge 220 and extend towards the working surface 101, and the second partial semi-circular hole wall extends towards the first abutting surface 210, and the second partial semi-circular hole wall is lower than the first partial semi-circular hole wall; of course, in other embodiments, the first vacuum hole 230 can also be a square hole, a rhombus hole, an irregular hole or other shaped holes, and the specific shape of the first vacuum hole 230 is not limited here. The first vacuum channel 300 can be a hole structure. At this time, the body 100 is a solid structural member, and the first vacuum channel 300 can be directly drilled inside the body 100 through a puncher; of course, in other embodiments, the first vacuum channel 300 can also be a pipe structure. At this time, the body 100 is a box-shaped structure with an accommodation chamber inside, and the first vacuum channel 300 is accommodated in this accommodation chamber; the vacuum device can be connected to the first vacuum hole 230 through the first vacuum channel 300 to provide an adsorption force for the first fixing part 200 to realize the adsorption of the workpiece 1 to be transferred.

[0039] In one example, when the first fixing portion 200 is polygonal, the multiple first vacuum holes 230 can be distributed at multiple corners of the first fixing portion 200 or on multiple sides of the first fixing portion 200, and the operator can flexibly design according to needs. In addition, it is optimal that the multiple first vacuum holes 230 are evenly distributed circumferentially to improve the uniform adsorption of the workpiece 1 to be transferred in the circumferential direction, improve the force uniformity of the workpiece 1 to be transferred, and improve the adsorption and fixing effect.

[0040] In a possible implementation manner, the first avoidance distance is 0.45 mm to 0.65 mm. In this example, the range of the first avoidance distance is optimized to make the first abutting surface 210 and the working surface 101 in a suitable height range, avoiding the problem that the vacuum adsorption space at the first fixing portion 200 is too large due to too large first avoidance distance, resulting in poor vacuum adsorption firmness and large vacuum adsorption energy consumption, improving the adsorption stability of the workpiece 1 to be transferred, and reducing energy consumption; or, avoiding the situation that the bottom of the workpiece 1 to be transferred is easily scratched by foreign objects on the first abutting surface 210 due to too small first avoidance distance, and improving the transfer safety of the workpiece 1 to be transferred.

[0041] As Figure 5 and Figure 7 shown, in a possible implementation manner, the first vacuum channel 300 includes a first main channel 310 and a plurality of first branch channels 320 communicating with the first main channel 310. The first branch channels 320 communicate with the first vacuum holes 230 and extend inward along the first direction Z of the body 100. One first branch channel 320 is correspondingly arranged with one first vacuum hole 230. The first main channel 310 extends outward along the second direction Y of the body 100, wherein the straight line where the second direction Y is located forms an included angle with the straight line where the first direction Z is located.

[0042] In this embodiment, the specific configuration of the first vacuum channel 300 is optimized. Specifically, the first vacuum channel 300 is configured as a combined component including at least a first main channel 310 and a plurality of first branch channels 320. The first main channel 310 can be a cylindrical gas flow channel, which is arranged inside the body 100 and extends outward along the second direction Y. Its inner end needs to extend at least to the corresponding position of the first branch channel 320 at the farthest end in the second direction Y to provide sufficient negative pressure for the first branch channel 320 at the farthest end in this direction, so as to provide sufficient adsorption force for the first vacuum hole 230 at the farthest end in this direction. Two first main channels 310 can be provided, and the two first main channels 310 can be arranged at intervals along the third direction X to provide sufficient adsorption force for a plurality of first vacuum holes 230. The first branch channel 320 can be a circular gas flow channel, which is arranged inside the body 100 and extends inward along the first direction Z from the first vacuum hole 230 to the first main channel 310. In this way, the negative pressure in the first main channel 310 can be provided to the first vacuum hole 230 to realize the adsorption and fixation of the belt transfer workpiece at the first vacuum hole 230. The first branch channel 320 can be perpendicularly connected to the first main channel 310 to shorten the vacuum path of the first vacuum channel 300, improve the adsorption efficiency and adsorption effect, and at the same time reduce the energy consumption of vacuum adsorption. The structure of the first vacuum channel 300 provided in this example is simple, the cooperation is compact, and the effective utilization rate is high. Moreover, the vacuum adsorption efficiency is high, the vacuum adsorption effect is good, and the energy consumption is low.

[0043] It should be noted that the first direction Z involved in this application can be the vertical direction perpendicular to the ground. At this time, the second direction Y can be the horizontal direction parallel to the ground, and the third direction X can be the horizontal direction parallel to the ground, and the straight line where the third direction X is located and the straight line where the second direction Y is located are on the same horizontal plane. The explanations of "the first direction Z", "the second direction Y" and "the third direction X" involved below are the same as above and will not be elaborated too much.

[0044] As Figure 2 、 Figure 3 、 Figure 5 And Figure 7 As shown in, in a possible implementation manner, the first vacuum channel 300 further includes an auxiliary channel 330. The auxiliary channel 330 is simultaneously connected to the first main channel 310 and the first branch channel 320 and extends outward along the third direction X of the body 100. Among them, the straight line where the third direction X is located, the straight line where the second direction Y is located, and the straight line where the first direction Z is located are set at an included angle. In this embodiment, the included angle can be set at a right angle or in a way approaching a right angle.

[0045] In this embodiment, the specific configuration of the first vacuum channel 300 is further optimized. Specifically, the first vacuum channel 300 is configured as a combined component including at least a first main channel 310, a plurality of first branch channels 320, and an auxiliary channel 330. The auxiliary channel 330 can be a cylindrical gas flow channel, which is arranged inside the body 100 and extends along the third direction X. Its inner end needs to extend at least to the corresponding position of the first branch channel 320 at the farthest end in the third direction X, so as to provide sufficient negative pressure for the first branch channel 320 at the farthest end in this direction, and thus provide sufficient adsorption force for the first vacuum hole 230 at the farthest end in this direction. The radial dimension of the auxiliary channel 330 is larger than that of the first main channel 310, so as to increase the negative pressure in the distal first branch channel 320 and the adsorption force at the distal first vacuum hole 230, and ensure the adsorption and fixation of the workpiece 1 to be transferred at the distal end. The first vacuum channel 300 provided in this example has more adsorption paths, stronger adsorption ability, and better adsorption effect.

[0046] As Figure 4 , Figure 5 and Figure 7 shown, in a possible implementation manner, the first fixing portion 200 further includes a blowing and suction hole 240, the blowing and suction hole 240 is arranged on the first abutting surface 210 and is located inside the plurality of first vacuum holes 230. The transfer jig 20 further includes a blowing and suction channel 400, the blowing and suction channel 400 is arranged inside the body 100 and is communicated with the blowing and suction hole 240.

[0047] In this embodiment, the specific configuration of the transfer jig 20 is further optimized. Specifically, the transfer jig 20 is configured as a combined component at least including a main body 100, a first fixing part 200, a first vacuum channel 300 and a blowing / suction channel 400. At the same time, a blowing / suction hole 240 is provided on the first fixing part 200. The blowing / suction hole 240 can be a circular hole. In the top view direction of the working surface 101, the blowing / suction hole 240 is a large-size hole, which is distributed in the middle area of the first fixing part 200, and a plurality of first vacuum holes 230 are small-size holes, which are distributed on the periphery of the first fixing part 200. Of course, in other embodiments, the blowing / suction hole 240 can also be a square hole, a rhombus hole, an irregular hole or other shaped holes. The specific shape of the blowing / suction hole 240 is not limited here. The blowing / suction channel 400 can be a hole structure. At this time, the main body 100 is a solid structural member, and the blowing / suction channel 400 can be directly opened inside the main body 100 by a punching tool. Of course, in other embodiments, the blowing / suction channel 400 can also be a pipe structure. At this time, the main body 100 is a box-shaped structure with an accommodating chamber inside, and the blowing / suction channel 400 is accommodated in this accommodating chamber. The blowing / suction device is communicated with the blowing / suction hole 240 through the blowing / suction channel 400 to provide blowing / suction force for the blowing / suction hole 240, so as to realize the purging and cleaning of the bottom of the workpiece 1 to be transferred, improve the cleaning effect of the workpiece 1 to be transferred, and facilitate subsequent packaging. The first fixing part 200 provided in this example can achieve the effects of intermediate purging and cleaning and peripheral adsorption and fixation. While improving the bottom cleaning of the workpiece 1 to be transferred, it improves the adsorption and fixation effect of the workpiece 1 to be transferred, which is beneficial to the accurate clamping, transfer and packaging of the subsequent gripper, and improves the packaging quality of the camera module.

[0048] As Figures 1 to 3 , Figure 5 , and Figure 7 shown, in a possible implementation manner, the main body 100 includes a connecting member 110 and a transfer base 120 provided on the connecting member 110. The working surface 101 is located on the side of the transfer base 120 away from the connecting member 110. The blowing / suction channel 400 includes a first channel 410 and a second channel 420 that are communicated. The first channel 410 extends from the blowing / suction hole 240 into the connecting member 110 along the first direction Z of the main body 100, and the second channel 420 is provided in the connecting member 110 and extends outward along the second direction Y of the main body 100.

[0049] In this embodiment, the specific configurations of the main body 100 and the blowing and suction channel 400 are optimized. Specifically, the main body 100 is configured as a combined component including at least a connecting member 110 and a transfer base 120. The connecting member 110 can be a plate-like structural member, on which there are through holes for fasteners such as screws / bolts to pass through. The through holes can extend along the first direction Z and penetrate through the connecting member 110. In this way, the connecting member 110 can be connected and fastened to the driving assembly 10 through the through holes to realize the position transfer of the transfer jig 20. The transfer base 120 can be a nearly square base body and can be arranged on one side of the connecting member 110 by means such as welding, so as to leave the other side of the connecting member 110 convenient for connecting it to the driving assembly 10. At the same time, the blowing and suction channel 400 is set as a composite structure including at least a first channel 410 and a second channel 420. The first channel 410 can be vertically connected to the second channel 420, and the first channel 410 is distributed in the middle of a plurality of first branch pipes and extends downward out of the first branch pipes and into the connecting member 110 without interfering with the vacuum adsorption air supply. The second channel 420 is correspondingly connected with two air holes. One is used to provide positive pressure gas to the blowing and suction channel 400 to realize the bottom blowing and cleaning of the workpiece 1 to be transferred, and the other is used to provide negative pressure gas to the blowing and suction channel 400 to realize the adsorption and impurity removal of foreign matters on the first abutting surface 210. The two air holes are arranged on the connecting member 110, and the air holes and the blower / negative pressure pump can be connected through a plastic hose or a metal pipe, etc. The transfer jig 20 provided in this example separately sets the vacuum adsorption area and the cleaning and impurity removal area, which can effectively avoid the interference between the two and improve the service performance of the transfer jig 20.

[0050] As Figure 4 shown, in a possible implementation manner, the first limiting edge 220 includes a connected vertical section 221 and an inclined section 222. One end of the vertical section 221 far from the inclined section 222 is connected to the first abutting surface 210, and one end of the inclined section 222 far from the vertical section 221 is connected to the working surface 101.

[0051] In this embodiment, the specific configuration of the first limiting edge 220 is optimized. Specifically, the first limiting edge 220 is configured as a combined component including at least a vertical section 221 and an inclined section 222. The vertical section 221 can be a nearly square column for providing a safe working distance in the first direction Z for the first abutting surface 210. The inclined section 222 can be a nearly trapezoid, which expands outwards to form a chamfer structure between the working surface 101 and the vertical section 221. It can not only increase the circumferential avoidance area of the first fixing part 200, increase the fault tolerance space of the lens group of the workpiece 1 to be transferred, and improve the applicable range of the transfer jig 20, but also reduce the collision damage to the workpiece 1 to be transferred and improve the use safety of the transfer jig 20.

[0052] As Figures 1 to 3 、Figures 5 to 7 As shown, in a possible implementation, it further includes a second fixing portion 500 and a second vacuum channel 600. The second fixing portion 500 includes a second abutting surface 510, a second limiting edge 520 surrounding the periphery of the second abutting surface 510, and a second vacuum hole 530. The side of the second limiting edge 520 away from the second abutting surface 510 is connected to the working surface 101 to form a second avoidance distance between the second abutting surface 510 and the working surface 101. The second vacuum hole 530 is located on the second abutting surface 510. The second vacuum channel 600 is provided in the body 100 and communicates with the second vacuum hole 530.

[0053] In this embodiment, the specific configuration of the transfer fixture 20 is further optimized. Specifically, the transfer fixture 20 is configured as a combined component including at least a main body 100, a first fixing part 200, a first vacuum channel 300, a second fixing part 500, and a second vacuum channel 600. The second fixing part 500 can be a nearly rectangular groove structure, which is arranged on the working surface 101 of the main body 100 and recessed into the main body 100 for realizing the transfer of the unloaded material. The second fixing part 500 is configured as a combined component including at least a second abutting surface 510, a second limiting edge 520, and a second vacuum hole 530. The second abutting surface 510 can be a plane, which is arranged below the working surface 101 and has a second avoidance distance from the working surface 101. This second avoidance distance can allow foreign matters to exist on the second abutting surface 510 and prevent scratching the bottom of the workpiece 1 to be transferred during vacuum adsorption; moreover, this second avoidance distance can also allow a certain packaging error or assembly error between the lens group and the bracket group of the workpiece 1 to be transferred, as long as the distance that the lens group protrudes downward from the bracket group is less than the second avoidance distance. The second limiting edge 520 can be a lateral skirt enclosing a nearly rectangle, with its bottom end arranged on the periphery of the second abutting surface 510 and its top end arranged on the working surface 101; the second limiting edge 520 can not only provide the second avoidance distance but also surround the periphery of the lens group of the workpiece 1 to be transferred to realize the positioning of the workpiece 1 to be transferred, improve the position accuracy of the workpiece 1 to be transferred, facilitate subsequent accurate transfer and packaging, and improve the packaging accuracy and packaging effect of the product. The second vacuum hole 530 can be a circular hole. In the top view direction of the working surface 101, the second vacuum holes 530 are distributed in the middle area of the second abutting surface 510; of course, in other embodiments, the second vacuum hole 530 can also be a square hole, a rhombus hole, an irregular hole, or other shaped holes, and the specific shape of the second vacuum hole 530 is not limited here. The second vacuum channel 600 can be a hole structure. At this time, the main body 100 is a solid structural member, and the second vacuum channel 600 can be directly opened inside the main body 100 by a puncher; of course, in other embodiments, the second vacuum channel 600 can also be a pipe structure. At this time, the main body 100 is a box-shaped structure with an accommodating chamber inside, and the second vacuum channel 600 is accommodated in this accommodating chamber; the vacuum device can be communicated with the second vacuum hole 530 through the second vacuum channel 600 to provide an adsorption force for the second fixing part 500 to realize the adsorption of the workpiece 1 to be transferred. The second fixing part 500 provided in this example can realize the middle single-point adsorption of the workpiece 1 to be transferred, with a large adsorption area, a large adsorption force, and a good adsorption effect; the transfer fixture 20 can at least simultaneously realize the middle single-point unloaded material adsorption and the edge multi-point incoming material adsorption of the workpiece 1 to be transferred, and can be applicable to different usage scenarios.

[0054] In a possible implementation, the second avoidance distance is 0.45 mm to 0.65 mm. In this example, the range of the second avoidance distance is optimized to make the second abutting surface 510 and the working surface 101 within a suitable height range, avoiding the problem that the vacuum adsorption space at the second fixing part 500 is too large due to the excessive second avoidance distance, resulting in poor vacuum adsorption firmness and high vacuum adsorption energy consumption, improving the adsorption stability of the workpiece 1 to be transferred, and reducing energy consumption; or, avoiding the situation that the bottom of the workpiece 1 to be transferred is easily scratched by foreign objects on the second abutting surface 510 due to the too small second avoidance distance, and improving the transfer safety of the workpiece 1 to be transferred.

[0055] As Figure 5 and Figure 7 shown, in a possible implementation, the second vacuum channel 600 includes a connected second main channel 610 and second branch channels 620. The second branch channels 620 are connected to the second vacuum holes 530 and extend inwards along the second direction Y of the body 100, and the second main channel 610 extends outwards along the first direction Z of the body 100.

[0056] In this embodiment, the specific configuration of the second vacuum channel 600 is optimized. Specifically, the second vacuum channel 600 is configured as a composite structure including at least a second main channel 610 and second branch channels 620. The second main channel 610 can be a cylindrical gas flow channel, arranged inside the body 100 and extending along the first direction Z; the second branch channels 620 can be circular gas flow channels, arranged inside the body 100 and vertically connected to the second main channel 610. The second branch channels 620 extend in the opposite direction to the first main channel 310 to avoid interference between the second vacuum channel 600 and the first vacuum channel 300, and ensure the vacuum pumping effect of the transfer jig 20. The structure of the second vacuum channel 600 provided in this example is simple, with a compact fit and high effective utilization rate; moreover, the vacuum adsorption efficiency is high, the vacuum adsorption effect is good, and the energy consumption is low.

[0057] In addition, as Figure 9 shown, the present application also provides a transfer device, including a driving component 10 and the transfer jig 20 as described above. The body 100 of the transfer jig 20 is arranged at the output end of the driving component 10. The specific structure of the transfer jig 20 refers to the above embodiment. Since this transfer device adopts all the technical solutions of the above all embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, and will not be elaborated here one by one.

[0058] In this embodiment, a transfer device that can intelligently control the position of the transfer jig 20 is provided. The driving assembly 10 can be configured to include at least a combination member of an X-axis rail 11, a Y-axis rail 12, and a Z-axis motor 13. The X-axis rail 11 can extend along the third direction X; the Y-axis rail 12 can be slidably connected above the X-axis rail 11 through a slider, and the Y-axis rail 12 extends along the second direction Y; the Z-axis motor 13 can be slidably connected to the Y-axis rail 12 through a connecting seat, and the Z-axis motor 13 can be driven along the third direction X. The transfer jig 20 can be connected to a camera module seat at the output end of the Z-axis motor 13 through fasteners such as screws / bolts. In this way, the Y-axis rail 12 can be driven to reciprocate along the X-axis rail 11, so as to realize the reciprocating movement of the Z-axis motor 13 and the transfer jig 20 in the third direction X; the Z-axis motor 13 can be used to reciprocate along the Y-axis, so as to realize the reciprocating movement of the transfer jig 20 in the second direction Y; the Z-axis motor 13 can be used to drive the transfer jig 20 to move up and down along the third direction X, so as to realize the precise control of the spatial position of the transfer jig 20, improve the position accuracy and reliability of the transfer jig 20, facilitate the transfer of incoming materials and outgoing materials, and enrich the usage scenarios of the transfer jig 20.
