[0038] To facilitate understanding of the present invention, the present invention will be described more fully below with reference to the accompanying drawings. The accompanying drawings illustrate preferred embodiments of the present invention. However, the present invention may be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the present disclosure.

[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one skilled in the art to which this invention pertains. The terms used herein in the specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0041] The present application provides a dart automatic assembly device, comprising a frame, a pressing mechanism, a feeding mechanism and a first driver; the pressing mechanism comprises a first pressing component and a second pressing component, the first pressing component and the second pressing component are horizontally spaced apart and arranged on the frame, and the first pressing component is movably arranged on the frame, the first pressing component forms a first clamping portion, the second pressing component forms a second clamping portion, and the central axis of the first clamping portion is aligned with the central axis of the second clamping portion; the feeding mechanism comprises a first loading component and a second loading component, the first loading component and the second loading component are both arranged adjacent to the pressing mechanism, the first loading component is used to place the dart body on the first clamping portion, and the second loading component is used to place the dart needle on the second clamping portion; the first driver is arranged on the frame, and the first driver is drivingly connected to the first pressing component, and the first driver is used to drive the first pressing component to approach or move away from the second pressing component.

[0042] In the aforementioned automatic dart assembly device, the first pressing assembly and the second pressing assembly are horizontally spaced apart on the frame, so that the first loading assembly places the dart body on the first clamping portion, and the second loading assembly places the dart pin on the second clamping portion, thereby achieving automatic loading of the dart body and dart pin. Furthermore, because the central axis of the first clamping portion of the first pressing assembly is aligned with the central axis of the second clamping portion of the second pressing assembly, when the first driver drives the first pressing assembly to move, the dart body in the first clamping portion can be inserted into the dart pin in the second clamping portion, thereby achieving automatic assembly of the dart body and dart pin, eliminating the need for manual assembly of the dart body and dart pin, thereby improving dart production efficiency and reducing dart production costs. Furthermore, because both loading and assembly are performed by equipment, the aforementioned automatic dart assembly device ensures a relatively constant output function of the first driver, thereby ensuring that relatively uniform dart products are obtained after assembly, that is, the length of the dart pin exposed from the dart body after assembly is uniform, thereby improving the yield rate of dart production. Furthermore, in the above-mentioned automatic dart assembly device, since the first pressing assembly and the second pressing assembly are arranged horizontally at intervals on the frame, the range of horizontal operation is increased, so that the first feeding assembly and the second feeding assembly are both arranged adjacent to the pressing mechanism, so that the dart needle and the dart body can be fixed on the second clamping part and the first clamping part at the same time from different horizontal directions, thereby increasing the loading speed and further improving the production efficiency of darts.

[0043] To better understand the technical solutions and beneficial effects of the present application, the present application is further described in detail below with reference to specific embodiments:

[0044] like Figure 1 As shown, the automatic dart production equipment 10 in one embodiment includes the automatic dart assembly device 10a to realize the automatic assembly of dart needles and dart bodies, avoiding manual input, thereby improving the production efficiency of darts. Furthermore, in one embodiment, the dart production equipment also includes a blanking mechanism 20a, a detection mechanism 30a, and a marking mechanism 40a. The blanking mechanism 20a, the detection mechanism 30a, and the marking mechanism 40a are all arranged on the frame 100. The detection mechanism 30a is used to detect the quality of the pressed darts to ensure the product quality of the assembled darts. The blanking mechanism 20a is used to send the pressed darts to the marking mechanism 40a for entering the next round of processing. The marking mechanism 40a is used to mark the dart body with a logo, thereby completing the automated production of darts and further improving the production efficiency of darts.

[0045] In one embodiment, the marking mechanism 40a includes a marking jig and a laser marking machine. The marking jig is used to secure the assembled darts, and the laser marking machine is used to mark the dart body. Furthermore, the marking jig forms a vacuum nozzle that is used to absorb the dart body, thereby securing it.

[0046] like Figures 2 to 3 As shown, in one embodiment, the dart automatic assembly device 10a includes a frame 100, a pressing mechanism 200, a feeding mechanism 300 and a first driver 400; the pressing mechanism 200 includes a first pressing component 210 and a second pressing component 220, the first pressing component 210 and the second pressing component 220 are horizontally spaced and arranged on the frame 100, and the first pressing component 210 is movably arranged on the frame 100, the first pressing component 210 forms a first clamping portion 211, the second pressing component 220 forms a second clamping portion 221, the central axis of the first clamping portion 211 is aligned with the center axis of the second clamping portion 221 The axes are aligned; the feeding mechanism 300 includes a first loading assembly 310 and a second loading assembly 320, and the first loading assembly 310 and the second loading assembly 320 are both arranged adjacent to the pressing mechanism 200, the first loading assembly 310 is used to place the dart body on the first clamping portion 211, and the second loading assembly 320 is used to place the dart needle on the second clamping portion 221; the first driver 400 is arranged on the frame 100, and the first driver 400 is driven and connected to the first pressing assembly 210, and the first driver 400 is used to drive the first pressing assembly 210 to approach or move away from the second pressing assembly 220.

[0047] In the above-mentioned automatic dart assembly device 10a, since the first pressing assembly 210 and the second pressing assembly 220 are horizontally spaced apart and arranged on the frame 100, the first loading assembly 310 places the dart body on the first clamping portion 211, and the second loading assembly 320 places the dart pin on the second clamping portion 221, thereby realizing automatic loading of the dart body and the dart pin. Moreover, since the central axis of the first clamping portion 211 of the first pressing assembly 210 is aligned with the central axis of the second clamping portion 221 of the second pressing assembly 220, when the first driver 400 drives the first pressing assembly 210 to move, the dart body in the first clamping portion 211 can be inserted into the dart pin in the second clamping portion 221, thereby realizing automatic assembly of the dart body and the dart pin, avoiding the need for manual assembly of the dart body and the dart pin, thereby improving the production efficiency of darts and reducing the production cost of darts.

[0048] In this embodiment, the output end of the first driver 400 is drivingly connected to the first pressing assembly 210 , so that the first driver 400 can move the first pressing assembly 210 .

[0049] Furthermore, the aforementioned automatic dart assembly device 10a, because both loading and assembly are performed using a single device, ensures a relatively constant output function of the first driver 400, thereby ensuring a relatively uniform dart product after assembly. Specifically, the length of the dart pins exposed from the dart body after assembly is uniform, thereby improving the yield rate of dart production. Furthermore, because the first loading assembly 310 and the second loading assembly 320 are both positioned adjacent to the pressing mechanism 200, the loading distance of the dart pins and dart bodies is shortened, thereby ensuring that the first loading assembly 310 and the second loading assembly 320 can quickly place the dart body and dart pins on the first clamping portion 211 and the second clamping portion 221, respectively, further improving dart production efficiency.

[0050] Furthermore, the above-mentioned dart automatic assembly device 10a, since the first pressing assembly 210 and the second pressing assembly 220 are arranged horizontally at intervals on the frame 100, the range of horizontal operation is increased, so that the first loading assembly 310 and the second loading assembly 320 are both arranged adjacent to the pressing mechanism 200, which not only shortens the loading distance of the dart needle and the dart body, but also enables the dart needle and the dart body to be fixed on the second clamping part 221 and the first clamping part 211 from different horizontal directions at the same time, thereby greatly improving the loading speed and further improving the production efficiency of darts.

[0051] like Figure 3 and Figure 6 As shown, in one embodiment, the first pressing assembly 210 includes a first sliding seat 212 and a first clamping portion 211. A guide rail 110 is provided on the frame 100. The first sliding seat 212 is slidably provided on the guide rail 110. The first clamping portion 211 is provided on the side of the first sliding seat 212 facing the second pressing assembly 220. The first driver 400 is drivingly connected to the first sliding seat 212, so that the first sliding seat 212 can be driven by the first driver 400 to move in a directional manner along the guide rail 110 to prevent the first sliding seat 212 from tilting during the sliding process, thereby ensuring that the central axis of the first clamping portion 211 and the central axis of the second clamping portion 221 can remain aligned, that is, the center of the dart body and the dart needle can remain aligned with each other, so that the dart needle can quickly and smoothly enter the inner hole of the dart body.

[0052] like Figure 6 and Figure 7As shown, in order to achieve the driving of the first sliding seat 212 by the first driver 400, in one embodiment, a sawtooth bar 2122 is provided on the side of the first sliding seat 212 facing away from the second sliding seat 222. A gear 410 is provided at the output end of the first driver 400, and the gear 410 and the sawtooth bar 2122 are mutually engaged to achieve relative sliding. When the output end of the first driver 400 is powered, it can drive the output end to rotate, thereby driving the gear 410 to mutually engage and slide on the sawtooth bar 2122 to achieve the driving of the first driver 400 on the first sliding seat 212. In one embodiment, the first driver 400 is a motor. In addition, because the first driver 400 and the sawtooth bar 2122 of the first sliding seat 212 mutually engage and slide, it can ensure that the first sliding seat 212 can move more balanced and reliably on the guide rail 110, effectively preventing the first sliding seat 212 from tilting during the sliding process.

[0053] In one embodiment, the extension direction of the sawtooth bar 2122 is perpendicular to the center point of the sliding seat, so that the sawtooth bar 2122 can be located at the center position of the first sliding seat 212. In this way, the first sliding seat 212 can move more balanced and reliably under the action of the first driver 400.

[0054] In one embodiment, a sliding groove is formed on a side of the first sliding seat 212 facing the frame 100 , and the sliding groove is adapted to the guide rail 110 to ensure that the first sliding seat 212 can move more balanced and reliably under the action of the first driver 400 .

[0055] like Figure 6 and Figure 8 As shown, in one embodiment, the first pressing assembly 210 further includes a second driver 213. The first sliding seat 212 defines a movable cavity, and the first clamping portion 211 is movably disposed within the movable cavity. The second driver 213 is drivingly connected to the first clamping portion 211 to enable the first clamping portion 211 to be movably disposed on the first sliding seat 212. This allows the inner hole of the dart body to be well fixed to the first clamping portion 211, thereby achieving the first clamping portion 211 to fix the dart body. In this embodiment, the second driver 213 is a servo motor, so that the servo motor can provide a power source for the first clamping portion 211.

[0056] like Figure 8 and Figure 10As shown, further, in one embodiment, the first clamping portion 211 is a clamping rod, and the clamping rod is formed with a threaded fixing portion 2111, which is used to fix the dart body. It can be understood that because the dart body has an inner hole, so that the dart body can be mounted on the clamping rod through the inner hole, and because the clamping rod is formed with the threaded fixing portion 2111, the side wall of the inner hole of the dart body is provided with an internal thread, so that the threaded fixing portion 2111 formed on the clamping rod can be threadedly engaged with the internal thread of the dart body, thereby achieving the clamping rod to fix the dart body, effectively preventing the first sliding seat 212 from shaking when sliding on the frame 100, which could cause the dart body on the clamping rod to shift or fall off, thereby ensuring that the center of the dart body and the dart needle are aligned with each other, so that the dart needle can quickly and smoothly enter the inner hole of the dart body. In this embodiment, the size of the clamping rod is adapted to the inner hole of the dart body, so that the dart body can be mounted on the clamping rod.

[0057] like Figure 10 and Figure 11 As shown, in one embodiment, the clamping rod includes a connecting portion 2112 and a positioning pin 2113 connected to each other, and the threaded fixing portion 2111 is provided on one end of the positioning pin 2113 close to the connecting portion 2112. It can be understood that since the positioning pin 2113 has a pointed end, the first loading assembly 310 can quickly put the dart body on the positioning pin 2113, thereby achieving rapid pre-fixation of the dart body. Then, the second driver 213 drives the connecting portion 2112 to continue to move, so that the threaded fixing portion 2111 can well enter the inner hole of the dart body and be threaded with the side wall of the inner hole of the dart body, thereby achieving fixation of the dart body, so as to prevent the dart body from easily falling or tilting when the first sliding seat 212 slides on the frame 100.

[0058] like Figure 11As shown, in one embodiment, the clamping rod further includes an elastic covering body 2114, which covers the outer wall of the positioning pin 2113, and the elastic covering body 2114 is correspondingly formed with an elastic threaded portion 2115. It can be understood that by adding the elastic covering body 2114 to the outer wall of the positioning pin 2113, on the one hand, the positioning pin 2113 can be fixed to the dart body, and on the other hand, due to the good elasticity of the elastic covering body 2114, the center of the dart body and the center of the dart needle can be fine-tuned to achieve mutual alignment of the center of the dart body and the center of the dart needle. In other words, when there is an error in the size of the inner hole of the dart body or the size of the dart needle in actual production, which easily causes the center of the dart body and the center of the dart needle to be misaligned, the present application adds the elastic covering body 2114 to the outer wall of the positioning pin 2113. The elastic coating 2114 allows the dart body and the dart pin to deform under external force when the dart body and the dart pin are pressed together, thereby fine-tuning the center of the dart body and the center of the dart pin, ensuring that the dart pin can be quickly pressed into the inner hole of the dart body, thereby ensuring that the dart body is not easily scrapped, thereby reducing production costs. Furthermore, the additional elastic coating 2114 can effectively reduce wear between the dart body and the positioning pin 2113, thereby preventing scratches at the contact point between the dart body and the positioning pin 2113, thereby ensuring the production quality of the dart. Furthermore, in this embodiment, the elastic coating 2114 is a silicone rubber.

[0059] In one embodiment, the threaded fixing portion 2111 includes at least one external thread ring, which is adapted to the internal thread of the dart body, thereby securing the dart body. Furthermore, in one embodiment, the number of external thread rings is 2 or 3. This ensures that the dart body is secured while ensuring a small number of external thread rings. This also facilitates the second driver 213 to quickly release the dart body, allowing the subsequent unloading mechanism 20a to quickly remove the dart body from the clamping rod and quickly enter the next round of marking operations, thereby improving dart production efficiency.

[0060] like Figure 10 and Figure 11 As shown, in one embodiment, the elastic covering body 2114 includes an elastic threaded portion 2115 and a wedge-shaped portion connected to each other, and the elastic threaded portion 2115 is arranged adjacent to the connecting portion 2112, so that the wedge-shaped portion can better adapt to dart bodies of different specifications, thereby improving the adaptability of the clamping rod to dart bodies of different specifications.

[0061] In one embodiment, the diameter of the wedge-shaped portion gradually decreases from the end close to the connecting portion 2112 to the end away from the connecting portion 2112. It can be understood that since the diameter of the wedge-shaped portion gradually decreases from the end close to the connecting portion 2112 to the end away from the connecting portion 2112, the cross-section of the wedge-shaped portion has a certain slope. In this way, on the one hand, the wedge-shaped portion can better adapt to dart bodies of different specifications, thereby improving the adaptability of the clamping rod to dart bodies of different specifications; on the other hand, when the dart body and the dart needle are pressed together, the wedge-shaped portion with a certain slope can better prevent the dart body from moving, thereby ensuring that the dart needle can be quickly pressed into the dart body, thereby improving the dart. production efficiency; on the other hand, since the wedge-shaped portion has a certain elasticity, it can effectively reduce the wear between the dart body and the positioning pin 2113, thereby avoiding the phenomenon of scratches easily appearing at the contact point between the dart body and the positioning pin 2113, thereby ensuring the production quality of the dart; on the other hand, the elastic threaded portion 2115 and the first sliding seat 212 can provide multi-level resistance to the displacement of the dart body, thereby further increasing the adaptability of the positioning pin 2113 to a variety of different specifications, and further improving the adaptability of the clamping rod to dart bodies of different specifications.

[0062] like Figure 3 、 Figure 6 and Figure 9 As shown, in one embodiment, the second pressing assembly 220 includes a second sliding seat 222 and a second clamping portion 221, the second clamping portion 221 is a pneumatic chuck, the pneumatic chuck is arranged on the second sliding seat 222, the pneumatic chuck is used to fix the dart needle, the second sliding seat 222 and the second sliding seat 222 are horizontally spaced apart on the frame 100, so as to realize the first pressing assembly 210 and the second pressing assembly 220 being horizontally spaced apart on the frame 100.

[0063] like Figure 9As shown, in one embodiment, the second sliding seat 222 is provided with a feeding cavity 2221 and a clamping cavity 2222 that are interconnected, so that the clamping cavity 2222 can accommodate a fixed block 2212, and the pneumatic chuck includes at least two fixed blocks 2212 and at least two cylinders 2213, each of the fixed blocks 2212 is movably arranged in the clamping cavity 2222, and each of the fixed blocks 2212 is relatively arranged in the clamping cavity 2222, so that each fixed block 2212 can form a clamping structure in the clamping cavity 2222, because each of the cylinders 2213 is arranged on the second sliding seat 222, and each of the cylinders 2213 is connected to a corresponding fixed block 2212. The fixed blocks 2212 are driven and connected, so that each fixed block 2212 is arranged in a one-to-one correspondence with each cylinder 2213 to form a plurality of independent ones. In this way, on the one hand, the dart pins are fixed. On the other hand, since each fixed block 2212 is controlled by the corresponding cylinder 2213, the user can combine and apply corresponding multiple fixed blocks 2212 and multiple cylinders 2213 according to actual clamping needs, thereby improving the clamping of dart pins of different specifications and shapes, thereby improving the adaptability to dart production. On the other hand, since each fixed block 2212 and each cylinder 2213 are independent individuals, the user can replace a damaged fixed block 2212 or cylinder 2213, thereby improving maintenance efficiency.

[0064] like Figures 3 to 5 As shown, in one embodiment, the second loading assembly 320 includes a vibration disk 321, a distributor 322, a feed pipe 323 and a third driver 324, the vibration disk 321 is arranged on the frame 100, the vibration disk 321 is formed with a connected vibration cavity 3211 and a discharge port 3212, the distributor 322 is provided with a distribution cavity 3221, the discharge port 3212 is connected to the feed pipe 323 through the distribution cavity 3221, the feed pipe 323 is connected to the second sliding seat 222, and the feed pipe 323 is connected to the feed cavity 2221, the third driver 324 is arranged on the frame 100, and the power end of the third driver 324 is movably arranged in the feed pipe 323 to deliver the dart needle into the clamping cavity 2222.

[0065] It can be understood that by setting the vibration plate 321 on the frame 100, the vibration plate 321 is fixed. Since the vibration plate 321 is formed with a connected vibration cavity 3211 and a discharge port 3212, so that the vibration cavity 3211 can hold a plurality of dart pins, the vibration plate 321 can vibrate under the action of an external power source, so that the plurality of dart pins placed in the vibration cavity 3211 can be sorted one by one. In this embodiment, the multiple dart pins are mainly ejected with their tips first, and then cooperate with the distributor 322 so that the tips of the dart pins first abut against the side walls of the feed tube 323. In this way, under the action of the gravity of the dart pins themselves and the distribution chamber 3221, the dart pins that fall into the feed tube 323 can be placed horizontally in the feed tube 323, and the tips of the dart pins can be located on the end away from the clamping chamber 2222. Since the feed tube 323 is connected to the feed chamber 2221, the power end of the third driver 324 can push the dart pins that fall into the feed tube 323 into the clamping chamber 2222 and push the dart pins to a preset position, and then start the pneumatic chuck to fix the dart pins.

[0066] In one embodiment, in order to achieve the sorting of multiple dart pins, it can be achieved by using the existing vibration plate 321. For example, patent CN109625801A discloses a vibration feed plate that can achieve the sorting of multiple dart pins of the present application. Therefore, this embodiment will not be described in detail.

[0067] In one embodiment, the first loading assembly 310 includes a loading robot 311 and a loading tray. The loading tray is disposed adjacent to the pressing mechanism 200 so that the loading tray can accommodate multiple dart bodies. The loading robot 311 is disposed on the frame 100 and is used to grab and fit the dart bodies from the loading tray onto the first clamping portion 211 to achieve loading of the dart bodies. Furthermore, since the loading robot 311 can achieve the grabbing and fitting of the dart bodies using an existing loading robot 311, such as the loading robot 311 arms disclosed in patents CN113547514A or CN109866286A, a detailed description thereof will not be given in this embodiment.

[0068] Furthermore, since the first sliding seat 212 and the second sliding seat 222 are horizontally arranged on the frame 100, and are used in conjunction with the first driver 400 and the third driver 324, the first driver 400 and the third driver 324 can be pressed together simultaneously from two opposite directions in the horizontal direction, thereby greatly improving the efficiency of the dart pressing assembly.

[0069] In this embodiment, the third actuator 324 is a hydraulic cylinder 2213. Due to the relatively accurate movement of the hydraulic cylinder 2213, the third actuator 324 can reliably and smoothly deliver the dart needle into the clamping cavity 2222, effectively preventing the dart needle from skewing during the delivery process. Furthermore, in one embodiment, the central axis of the third actuator 324, the central axis of the feed tube 323, the central axis of the feed cavity 2221, and the central axis of the clamping cavity 2222 are aligned with each other, thereby enabling the third actuator 324 to more reliably and smoothly deliver the dart needle into the clamping cavity 2222.

[0070] In one embodiment, the length of the clamping cavity 2222 is 23 mm to 27 mm, so that the dart needle can protrude 15 mm to 20 mm under the action of the third driver 324, thereby forming a preset pushing position to ensure that darts of uniform specifications are assembled.

[0071] In one embodiment, the feed pipe 323 is formed with a feed port 3231 , and the feed port 3231 is communicated with the distribution cavity 3221 to achieve communication between the feed pipe 323 and the distribution cavity 3221 , thereby ensuring that the dart needle can fall into the feed port 3231 .

[0072] like Figure 3 and Figure 4 As shown, in one embodiment, the divider 322 is tilted on the feed tube 323, so that the dart pins from the discharge tube can fall into the feed tube 323 in a relatively balanced and reliable manner. Furthermore, in one embodiment, the angle of inclination between the extension direction of the divider 322 and the extension direction of the feed tube 323 is 25 degrees to 55 degrees, so as to ensure that the dart pins can fall into the feed tube 323 in a balanced and reliable manner.

[0073] In one embodiment, the material distribution chamber 3221 is in an inverted funnel shape, so that one end of the material distribution chamber 3221 has a leakage opening, and the leakage opening is located adjacent to the discharge port 3212. It can be understood that by configuring the material distribution chamber 3221 in an inverted funnel shape, the material distribution chamber 3221 has a structure that is narrow at the top and wide at the bottom, and the leakage opening and the feed port 3231 are both greater than or equal to the length of the dart needle, so that the dart needle can pass through the leakage opening of the material distribution chamber 3221 and fall into the feed port 3231. When the dart needle is blocked by the side wall of the feed tube 323 and the action of gravity, the dart needle that falls into the feed port 3231 can be better converted from a vertical position to a horizontal position, so that the third driver 324 can push the dart needle into the clamping chamber 2222.

[0074] In order to ensure that the dart needle at the discharge port 3212 does not fall when entering the distributor 322, the discharge port 3212 of the vibration plate 321 is formed with an inclined bending portion, and the inclined bending portion is at least partially located in the distribution cavity 3221 to ensure that the dart needle at the discharge port 3212 can reliably and stably enter the distribution cavity 3221.

[0075] Furthermore, in one embodiment, the distance between the inclined bend and the feed inlet 3231 is greater than or equal to the length of the dart pins, ensuring that the dart pins dropped into the feed inlet 3231 can be easily moved within the material distribution chamber 3221, thereby enabling the dart pins to be transferred from a vertical position to a horizontal position. Furthermore, because the inclined bend has a slope, the dart pins can fall into the feed inlet 3231 more quickly under the action of gravity, thereby increasing the speed of material loading.

[0076] In one embodiment, the dart automatic assembly device 10a further includes a positioning structure 500, which is arranged between the first pressing component 210 and the second pressing component 220, and the positioning structure 500 is movably connected to the frame 100. The positioning structure 500 is used to fix the dart body and the dart needle when the first pressing component 210 and the second pressing component 220 are pressed together. In this way, by adding the positioning structure 500 between the first pressing component 210 and the second pressing component 220, the dart body and the dart needle can be prevented from being misaligned when they are assembled and pressed together.

[0077] like Figure 9 As shown, in one embodiment, the positioning structure 500 includes a positioning plate 510, a first guide column 520, a second guide column 530, a first elastic member and a second elastic member, the first guide column 520 is connected to the second sliding seat 222 through the first elastic member, the second guide column 530 is connected to the second sliding seat 222 through the second elastic member, the positioning plate 510 is connected to the first guide column 520 and the second guide column 530 respectively, the positioning plate 510 is provided with a positioning hole 511, and the central axis of the positioning hole 511 is aligned with the first clamping rod. The central axes are aligned with each other, so that when the first driver 400 drives the first sliding seat 212 to move closer to the second sliding seat 222, the dart body can be well fixed in the positioning hole 511, and the first elastic member and the second elastic member can be deformed under the force of the first driver 400, so that the dart body on the positioning plate 510 can move closer to the pneumatic chuck, so that the dart pin can be pressed into the dart body, thereby avoiding the dart body and the dart pin from being easily misaligned during pressing, thereby achieving the fixation of the dart body and the dart pin when the first pressing assembly 210 and the second pressing assembly 220 are pressed together.

[0078] In one embodiment, the positioning hole 511 includes a first speaker positioning sub-hole 5111, a buffer hole 5112 and a second speaker positioning sub-hole 5113 which are connected in sequence, and the trumpet mouths of the first speaker positioning sub-hole 5111 and the second speaker positioning sub-hole 5113 are both set toward the outer surface of the positioning plate 510.

[0079] It should be noted that, since the first clamping portion 211 can move simultaneously in two horizontally opposite directions under the action of the first driver 400 and the second clamping rod can move simultaneously under the action of the third driver 324, a large friction force is generated when the dart needle contacts the dart body, which not only causes one end of the dart body to be easily scratched, but also easily causes the center of the dart body and the dart needle to be misaligned. Therefore, the present application arranges the positioning hole 511 to be sequentially connected with the first speaker positioning sub-hole 5111, the buffer hole 5112, and the second speaker positioning sub-hole 5113. Since the first speaker positioning sub-hole 5111 and the second speaker positioning sub-hole 5113 have large horn openings, it is convenient for the dart body and the dart needle to quickly enter the first speaker positioning sub-hole 5111 and the second speaker positioning sub-hole 5113 from both sides of the positioning plate 510 at the same time, thereby improving the production efficiency of darts. In addition, the first speaker positioning sub-hole 5111 can fix the dart body so that the dart needle can be pressed into the dart body steadily and reliably, thereby ensuring the production quality of darts. On the other hand, due to A buffer hole 5112 is provided between the first speaker positioning hole 5111 and the second speaker positioning hole 5113 to allow for a spacing between the dart body and the dart pin. The buffer hole 5112 effectively reduces friction when the dart body and the dart pin contact each other, thereby preventing scratches on one end of the dart body. It also prevents misalignment between the centers of the dart body and the dart pin, thereby improving dart production efficiency and ensuring product quality. Furthermore, the first speaker positioning hole 5111 and the second speaker positioning hole 5113 can accommodate dart bodies and dart pins of various specifications, thereby improving the adaptability of the dart automatic assembly device 10a. In one embodiment, the first speaker positioning hole 5111 is adapted to the dart body, allowing the dart body to be quickly inserted and secured within the first speaker positioning hole 5111.

[0080] In one embodiment, the diameter of the buffer hole 5112 is not less than the minimum diameter of the second speaker positioning sub-hole 5113, and the second speaker positioning sub-hole 5113 is adapted to the dart needle. In this way, the dart needle can be reliably and smoothly pressed into the dart body under the action of the third driver 324, so as to realize automatic pressing and assembly of the dart needle and the dart body.

[0081] In one embodiment, a method for automatically producing darts is provided: first, a plurality of dart bodies are vertically placed on a loading tray, and a plurality of dart pins are placed on a vibration plate 321. Then, the dart bodies are sleeved on the positioning pins 2113 by the loading robot 311, and the second driver 213 is activated to pre-fix the dart bodies, that is, to achieve the fixation of the dart bodies. At the same time, the plurality of dart pins are sorted by the vibration plate 321, and the dart pins are changed from a vertical state to a horizontal state through the distribution cavity 3221 of the distributor 322, that is, to achieve the loading of the dart pins. Subsequently, the first driver 400 and the third driver 324 are respectively activated. As a result, the first driver 400 can drive the dart body to move, and the third driver 324 can drive the dart pin to move, so that the dart body and the dart pin can enter the positioning hole 511 respectively. Then, the third driver 324 and the first driver 400 are driven continuously, so that the dart pin can be reliably and evenly pressed into the dart body, thereby completing the press-fit assembly of the dart body and the dart pin. Then, the detection mechanism 30a is used to detect the pressed darts to ensure that qualified darts can flow into the next marking process through the unloading mechanism 20a. Finally, the dart body is marked by the marking mechanism 40a, thereby completing the automated production of darts.

[0082] Compared with the prior art, the present invention has at least the following advantages:

[0083] 1. In the above-mentioned automatic dart assembly device 10a, since the first pressing assembly 210 and the second pressing assembly 220 are horizontally spaced apart on the frame 100, the first loading assembly 310 places the dart body on the first clamping portion 211, and the second loading assembly 320 places the dart pin on the second clamping portion 221, thereby realizing automatic loading of the dart body and the dart pin. Moreover, since the central axis of the first clamping portion 211 of the first pressing assembly 210 and the central axis of the second clamping portion 221 of the second pressing assembly 220 are aligned with each other, when the first driver 400 drives the first pressing assembly 210 to move, the dart body in the first clamping portion 211 can be inserted into the dart pin in the second clamping portion 221, thereby realizing automatic assembly of the dart body and the dart pin, avoiding manual assembly of the dart body and the dart pin, thereby improving the production efficiency of darts and reducing the production cost of darts.

[0084] 2. The above-mentioned dart automatic assembly device 10a, since both loading and assembly are performed by equipment, ensures that the output function of the first driver 400 is relatively constant, and further ensures that relatively uniform dart products can be obtained after assembly. That is, it ensures that the length of the dart pin exposed on the dart body after assembly is uniform, thereby improving the yield rate of dart production.

[0085] 3. In the above-mentioned automatic dart assembly device 10a, since the first pressing assembly 210 and the second pressing assembly 220 are arranged horizontally and spaced apart on the frame 100, the range of horizontal operation is increased, so that the first loading assembly 310 and the second loading assembly 320 are both arranged adjacent to the pressing mechanism 200. This not only shortens the loading distance of the dart needle and the dart body, but also enables the dart needle and the dart body to be fixed to the second clamping portion 221 and the first clamping portion 211 from different horizontal directions at the same time, thereby greatly improving the loading speed and further improving the production efficiency of darts.

[0086] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
