[0011] In one embodiment of the present invention, the driving mechanism includes: A driving component is disposed on the base; A transmission component is connected to the driving component. One end of the transmission component is provided with a slot, and one end of the material distribution component is inserted into the slot and fixedly connected to the transmission component. A slide rail is provided on the base and located outside the positioning member, and the material distribution member is slidably disposed on the slide rail.

[0012] In one embodiment of the present invention, the surface of the positioning member facing away from the material box is further provided with a clearance groove, and the ejecting mechanism includes: A lifting mechanism is provided on the base; The top material seat is connected to the lifting mechanism.

This ensures successful picking every time, improving accuracy and thus assembly efficiency. Furthermore, since the positioning holes in the positioning component are fixed, the picking position is also fixed each time, reducing positioning difficulty and improving picking efficiency, thereby increasing the efficiency of lens assembly.

[0018] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0020] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0021] In this invention, unless otherwise explicitly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0022] Furthermore, in this invention, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the word "and / or" throughout the text means including three parallel solutions; taking "A and / or B" as an example, it includes solution A, solution B, or a solution that simultaneously satisfies A and B. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0023] The lens module includes a sphere to assist in adjusting the focal length. In related technologies, during the assembly of the lens module, the sphere is received as a whole box of materials. Due to the small diameter of the sphere, the material-retrieving mechanism directly retrieves it from the box, which can easily lead to over-retrieval or under-retrieval, making it impossible to ensure successful retrieval every time. This results in low assembly efficiency for the lens assembly.

[0024] To solve the above-mentioned technical problems, this application provides a material dispensing device 100.

[0025] Reference Figures 1 to 5In one embodiment of this application, the material dispensing device 100 includes a base 10, a positioning member 20, a material box 30, a top-feeding mechanism 60, and a driving mechanism 50. The positioning member 20 is disposed on the base 10, and its surface has a first position and a second position spaced apart. The surface of the second position is recessed with a positioning hole. The material box 30 is disposed on top of the positioning member 20 and forms a gap with the positioning member 20. The material box 30 has an internal receiving cavity, and the bottom of the receiving cavity has a discharge port 353. The top-feeding mechanism 60 is vertically and vertically disposed at the bottom of the positioning member 20, and the top-feeding mechanism 60 can pass through the positioning hole. The driving mechanism 50 is disposed on the base 10 and connected to the material box 30. The driving mechanism 50 drives the material box 30 to reciprocate between the first position and the second position. When the material box 30 moves to the second position, the ball contained in the material box 30 falls into the positioning hole through the discharge port 353; When the material box 30 leaves the second position, the ejector mechanism 60 ejects the ball that has fallen into the positioning hole from the surface of the positioning member 20.

[0026] The base 10 provides an installation carrier for the positioning component 20, the material box 30, the top material mechanism 60, and the drive mechanism 50. As the supporting bottom of the entire material distribution device 100, the base 10 provides a stable and sturdy installation platform to ensure that the device remains stable during operation.

[0027] The positioning element 20 can be made of metal to improve its structural strength and facilitate high-precision machining of the positioning holes. The positioning element 20 can be fixed to the surface of the base 10 using screws or other connecting structures. The positioning element 20 is roughly a rectangular plate with a first direction and a second direction perpendicular to each other. The first and second positions are arranged along the second direction. Alternatively, the first and second positions can be understood as two specific areas along the length of the positioning element 20, which could be either the two ends of the length direction or near the two ends; therefore, the first and second positions are not marked in the figure. The surface of the positioning element 20 has recessed positioning holes, which can be one, multiple spaced holes, or multiple holes of different sizes. The positioning hole is located in the second position. The positioning hole is used to receive and position the ball. Understandably, the diameter and depth of the positioning hole are slightly larger than the diameter of the ball, so that when the material box 30 leaves the second position, the positioning hole contains one ball. The remaining balls are kept in the receiving cavity due to the small gap between the positioning member 20 and the material box 30. It can be understood that when the material box 30 moves from the first position to the second position and then returns to the first position, only one ball is ensured in one positioning hole.

[0028] The material box 30 is used to accommodate spheres. Understandably, if the material box 30 has only one cavity, it can only accommodate spheres of one size. When it needs to accommodate spheres of multiple sizes, multiple cavities will be provided. The number of discharge ports 353 at the bottom of the material box 30 can be one or more, depending on the actual quantity of material to be retrieved. Understandably, the top of the material box 30 can also have a feed port 331 to facilitate adding material into the cavity. The material box 30 is movably positioned on top of the positioning member 20. The gap between the material box 30 and the positioning member 20 should be smaller than the diameter of the sphere to ensure that no sphere is contained in the gap between the material box 30 and the positioning member 20 when the material box 30 moves between the first and second positions. The material box 30 can be a one-piece structure or a split structure. A split material box 30 can be made of metal to facilitate the processing of its internal structure.

[0029] The ejector mechanism 60 is located at the bottom of the positioning member 20. The ejector mechanism 60 is used to lift the ball located inside the positioning hole to the surface of the protruding positioning member 20 so as to facilitate the subsequent ball picking operation of the assembly equipment.

[0030] In the technical solution of this application, by setting a positioning component 20, a material box 30, a top-feeding mechanism 60, and a driving mechanism 50 on the base 10, the spheres in the material box 30 can be accurately divided and positioned. Thus, when the picking mechanism in the assembly equipment moves above the top-feeding mechanism 60 to pick up the spheres, the technical problem of inaccurate sphere picking in the prior art is solved, ensuring that the picking mechanism can successfully pick up spheres every time, improving the accuracy of picking up spheres, and thus improving the efficiency of assembly. Furthermore, since the positioning hole position in the positioning component 20 is fixed, the picking position of the picking mechanism is also fixed each time, reducing the positioning difficulty during picking up spheres, improving the efficiency of picking up spheres, and thus improving the efficiency of lens assembly.

[0031] Reference Figures 2 to 4 In one embodiment of the present invention, the receiving cavity includes a first cavity 314 and a second cavity 315 spaced apart, and the spheres include a first sphere 91 and a second sphere 93 with different diameters. The first cavity 314 is used to accommodate the first sphere 91, and the second cavity 315 is used to accommodate the second sphere 93. The positioning holes include a first positioning hole 21 and a second positioning hole 23 spaced apart. The first positioning hole 21 and the second positioning hole 23 are spaced apart along a first direction, which is at an angle to the moving direction of the material box 30. The first positioning hole 21 is used to position the first sphere 91, and the second positioning hole 23 is used to position the second sphere 93.

[0032] In one embodiment of the technical solution of this application, the number of receiving cavities and the number of positioning holes are related to the product to be assembled.

[0033] Reference Figure 7 and Figure 8 The product to be assembled in this application is a lens module 90, which includes a metal shield 97, a bracket 95 disposed inside the metal shield 97, and a lens body 96. The circuit components are located on the bracket 95. To allow the lens body 96 to move relative to the bracket 95 to adjust the focal length, two sets of rolling components are typically provided between the lens body 96 and the bracket 95 to assist in the movement of the lens body relative to the bracket 95. Each set of rolling components includes two types of spheres: a first sphere 91 with a diameter of 0.6 mm and two second spheres 93 with a diameter of 0.7 mm. The two second spheres 93 are located on either side of the first sphere 91. Therefore, the receiving cavity needs to be configured as a first cavity 314 and a second cavity 315 spaced apart from each other, which can respectively accommodate the first spheres 91 and the second spheres 93 of different sizes. Correspondingly, the positioning holes also include first positioning holes 21 and second positioning holes 23 of different sizes. The first positioning holes 21 and second positioning holes 23 are spaced apart along a first direction, which forms an angle with the moving direction of the material box 30. In this way, the material box 30 can simultaneously separate two different sizes of spheres during a single movement, improving material separation efficiency. Simultaneously, by arranging the two different sizes of spheres along the first direction, the material handling mechanism in the assembly equipment can sequentially handle the two different sizes of spheres, thereby improving material handling efficiency and, consequently, assembly efficiency. Understandably, in addition to their positional differences, the first positioning holes 21 and second positioning holes 23 are also adaptively designed according to the sizes of the first sphere 91 and the second sphere 93 to further enhance the reliability of positioning the first sphere 91 and the second sphere 93.

[0034] Reference Figures 2 to 4 In one embodiment of the present invention, there are two first positioning holes 21, which are spaced apart along a first direction; there are four second positioning holes 23, which are arranged in two rows along the first direction, wherein, in the moving direction of the material box 30, the first positioning hole 21 is located in the middle of the two second positioning holes 23.

[0035] In one embodiment of this application, by positioning the first positioning hole 21 in the middle of the two second positioning holes 23, one picking head of the picking mechanism in the assembly equipment can first pick up the first sphere 91 positioned by the first positioning hole 21. Then, the picking mechanism can pick up the two second spheres 93 on the two second positioning holes 23 simply by translation. That is, one picking head can simultaneously complete the picking and sorting operations of one first sphere 91 and two second spheres 93. After the picking mechanism completes the picking, it can place the first sphere 91 and the second sphere 93 according to the positions required by the lens assembly. After placement, the positions of the first sphere 91 and the second sphere 93 are the positions required for assembly, improving the reliability of picking and sorting. Furthermore, since the diameter of the first sphere 91 is smaller than the diameter of the second sphere 93, when picking up the second sphere 93, the first sphere 91 will not interfere with or collide with other components, ensuring the feasibility of the picking operation.

[0036] Reference Figure 1 , Figures 4 to 6 In one embodiment of the present invention, the material box 30 includes a base 31, a cover 33, and a distributing component 35. The base 31 has a recessed receiving groove 311 on its surface opposite to the positioning component 20, and the bottom wall of the receiving groove 311 has a through hole 313. The cover 33 is detachably connected to the base 31 and covers the opening of the receiving groove 311. The cover 33 and the receiving groove 311 enclose the receiving cavity. The cover 33 also has a feed inlet 331 communicating with the receiving cavity. The distributing component 35 is located at the bottom of the base 31 and has a gap with the surface of the positioning component 20. The distributing component 35 has a plurality of distributing grooves 351 corresponding to the through hole 313. The bottom of each distributing groove 351 has a discharge port 353. The distributing component 35 is also connected to the driving mechanism 50.

[0037] In one embodiment of this application, the material box 30 is configured as a split structure. The base 31, cover 33, and dispensing component 35 are all made of metal to ensure structural strength. The split design also facilitates the processing of the internal structure of the material box 30. The surface of the base 31 facing away from the positioning component 20 is recessed with a receiving groove 311. The receiving groove 311 is inclined downwards from the first position towards the second position. This inclined design helps the ball flow naturally to the bottom of the receiving groove 311 under gravity, reducing the ball's long-term stagnation in the receiving groove 311 and improving the efficiency of successful ball dispensing. Understandably, when the material box 30 has multiple receiving cavities, the number of receiving grooves 311 corresponds to the number of receiving cavities. The cover 33 is detachably connected to the base 31 and covers the opening of the receiving groove 311, forming a receiving cavity. The cover 33 is also provided with an inlet 331 communicating with the receiving cavity, through which balls can be added to the receiving cavity. In one embodiment, a top cover 36 can also be provided on the cover 33 to seal the feed inlet 331, thereby preventing dust and other debris from entering the receiving groove 311 under normal conditions. When the material box 30 has multiple receiving cavities, that is, when the material box 30 has a first cavity 314 and a second cavity 315, the number of feed inlets 331 is also two. At the same time, a mark is provided on the surface of the cover 33 to indicate the different sizes of the spheres contained in the first cavity 314 and the second cavity 315. For example, the mark can be "large" or "small" to facilitate differentiation and avoid errors during material addition.

[0038] In one embodiment, a portion of the cover 33 is transparent to facilitate observation of the state and number of spheres within the receiving cavity, ensuring that operators can monitor the number and state of the spheres in real time. Understandably, the cover 33 may include a cover body and a transparent cover plate. The cover body has a window 333, which is covered with glass. The glass has good light transmittance, allowing observation of the number of spheres within the receiving groove 311.

[0039] The material distribution component 35 is located at the bottom of the base 31 and is used to distribute the spheres within the receiving groove 311. Understandably, one receiving groove 311 holds one type of sphere. Since the lens assembly has two sets of rolling components, it is necessary to distribute the same type of sphere within one receiving groove 311 into two outlets 353 for discharge. The material distribution component 35 provides two material distribution grooves 351 corresponding to each receiving groove 311. The sum of the widths of the openings of the two material distribution grooves 351 is greater than the through hole 313 at the bottom of the receiving groove 311 to prevent material leakage. Each material distribution groove 351 has an outlet 353 at its bottom. The outlet 353 can be configured to extend along the moving direction of the material box 30, and the width of the outlet 353 is adapted to the diameter of the sphere to prevent material leakage.

[0040] Reference Figure 1 , Figures 4 to 6 In one embodiment of the present invention, the material dispensing device 100 further includes a detection component 70, which includes a signal transmitter 71 and a signal receiver 73 respectively disposed on opposite sides of the material dispensing trough 351.

[0041] In one embodiment of the present invention, the detection component 70 includes a signal transmitter 71 and a signal receiver 73 respectively disposed on opposite sides of the dispensing trough 351. The detection component 70 can monitor the remaining status of the balls in the dispensing trough 351. When there are no balls in the dispensing trough 351, there is no obstruction between the signal transmitter 71 and the signal receiver 73. The signal receiver 73 receives a material shortage signal and can issue an alarm signal. The operator can then add balls to the receiving trough in a timely manner based on the alarm information.

[0042] Reference Figure 5 and Figure 6 In one embodiment of the present invention, the positioning member 20 is further provided with a waste hole 25, the waste hole 25 is located on the side of the first position away from the second position, and the base 10 is further provided with a waste box 80, the waste box 80 being provided corresponding to the waste hole 25.

[0043] In one embodiment of the present invention, the waste hole 25 is located on the side away from the positioning hole. The number of waste boxes 80 in the waste hole 25 corresponds to the number of accommodating cavities. Correspondingly, the number of waste boxes 80 also corresponds to the number of accommodating cavities. The waste boxes 80 are used to collect the waste balls falling from the waste hole 25, which facilitates subsequent processing and ensures the cleanliness and environmental protection of the entire material distribution process.

[0044] Reference Figures 1 to 4 In one embodiment of the present invention, the driving mechanism 50 includes a driving member 51, a transmission member 53, and a slide rail 55.

[0045] In one embodiment of the present invention, a drive mechanism 50 is disposed on a base 10 and connected to a material box 30. The drive mechanism 50 drives the material box 30 to move between a first position and a second position. The drive mechanism 50 includes a drive component 51, a transmission component 53, and a slide rail 55. The drive component 51 can be a linear module, a linear motor, a cylinder, an electric cylinder, etc. The drive component 51 is disposed on the base 10 and provides power to the entire system. The transmission component 53 is connected to the drive component 51 and has a plate-like structure. One end of the transmission component 53 has a slot 531, and one end of the material distribution component 35 is inserted into the slot 531 and fixedly connected to the transmission component 53. The slide rail 55 is disposed on the base 10 and located outside the positioning component 20. The number of slide rails 55 can be one or two arranged opposite each other. The material distribution component 35 is slidably disposed on the slide rail 55. The arrangement of the slide rail 55 can ensure the smoothness and accuracy of the movement of the material box 30 and avoid material distribution errors caused by unstable movement.

[0046] In one embodiment of the present invention, the positioning member 20 is further provided with a relief groove 27 on the surface away from the material box 30. The top material mechanism 60 includes a lifting mechanism 61, a top material seat 63 and a top material member 65. The lifting mechanism 61 is disposed on the base 10. The top material seat 63 is connected to the lifting mechanism 61. The top material member 65 is accommodated in the relief groove 27. The top material seat 63 is further provided with an installation groove 631. The top material seat 63 is also provided with an airflow channel communicating with the installation groove 631. The top material member 65 is disposed in the installation groove 631. One end of the top material member 65 extends into the positioning hole, and the two ends of the top material member 65 are also connected to form an air passage.

[0047] In one embodiment of the present invention, a top-feeding mechanism 60 is vertically mounted on a base 10 and passes through a positioning hole to eject a ball from the positioning hole. The top-feeding mechanism 60 includes a lifting mechanism 61, a top-feeding seat 63, and a top-feeding component 65. The lifting mechanism 61 is mounted on the base 10 and can be a lifting module, a linear motor, a cylinder, an electric cylinder, etc. The lifting mechanism 61 controls the vertical movement of the top-feeding seat 63. The top-feeding seat 63 is connected to the lifting mechanism 61 and is housed within a clearance groove 27. The top-feeding seat 63 also has an installation groove 631 and an airflow channel communicating with the installation groove 631. One end of the airflow channel is connected to a pinhole air source. The top material 65 is located in the mounting groove 631. One end of the top material 65 extends into the positioning hole, and the two ends of the top material 65 are connected to form an airflow channel to facilitate airflow through the top material 65. When the top material 65 rises, the air source forms a vacuum negative pressure to firmly hold the ball in place, ensuring that the ball will not move or fall, and ensuring that the ball can be smoothly pushed out of the positioning hole.

[0048] Understandably, multiple ejector components 65 can be simultaneously mounted on a single ejector seat 63. (Refer to...) Figure 4 There are two top material seats 63, which are used to lift the first ball 91 and the second ball 93 respectively. The top material seat 63 used to lift the first ball 91 has two top material components 65, and the top material seat 63 used to lift the second ball 93 has four top material components 65. In this way, one top material mechanism 60 can lift 6 balls at the same time.

[0049] The present invention also proposes an assembly device (not shown), which includes a material handling mechanism (not shown) and a material dispensing device 100. The specific structure of the material dispensing device 100 is as described in the above embodiments. Since the assembly device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0050] The material handling mechanism includes two spaced-apart material handling heads. During material handling, the material handling device first moves above the first positioning hole 21, and the two material handling heads simultaneously take away two first spheres 91. Then, the material handling device moves above the second positioning hole 23 and simultaneously takes away four second spheres 93. At this time, the material handling device can simultaneously place the first spheres 91 and second spheres 93 in the position to be assembled according to their positional relationship during installation and assembly, thereby improving the efficiency of lens assembly.

[0051] In this application, the material box 30 can separate 6 spheres at the same time by reciprocating once, and the separated spheres are precisely positioned. The top material mechanism 60 can lift 6 spheres at a time, and the material picking mechanism can pick up a total of 6 spheres in two pickings. The material loading of a lens module 90 can be completed in one feeding, which improves the material picking and feeding efficiency, and thus improves the assembly efficiency of the lens module 90.

[0052] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
