Description

Technical Field

[0001] This application belongs to the field of machining technology, and in particular relates to a precision parts processing equipment and its loading fixture. Background Technology

[0002] With continuous social progress and rapid technological development, the market demand for many products is increasing, and the requirements are becoming more stringent. Therefore, it is essential to both ensure product quality and improve production efficiency to meet market demands. Currently, many high-tech products use components that are not only tiny but also require high precision in their appearance. Especially for precision components, even minor scratches on their surface can have extremely unstable effects on their operation. For example... Figure 1 The circular micro-workpiece shown requires circumferential inspection during the production process, specifically through rotational observation under an electron microscope. This necessitates the use of a fixture, which must pre-load the workpiece. Due to its tiny size, the workpiece is difficult to fit into the storage compartment of the fixture, and the current manual filling method is inefficient. Furthermore, manual operation is prone to instability, particularly the risk of the workpiece colliding with the side wall of the storage compartment during filling, causing it to bounce and fall. Such tiny workpieces are not only difficult to locate, but also prone to damage upon impact, resulting in a low yield rate. Summary of the Invention

[0003] The purpose of this application is to provide a precision parts processing equipment and its filling fixture to solve the technical problems of low efficiency in the filling operation of precision parts and the easy occurrence of accidents leading to product loss and damage in the prior art.

[0004] To achieve the above objectives, the technical solution adopted in this application is: to provide a filling fixture, comprising:

[0005] The material tray is provided with multiple storage slots for filling workpieces, and the multiple storage slots are arranged side by side on the material tray;

[0006] The container is equipped with a feed inlet for connection to a discharge device;

[0007] A bracket is disposed inside the container, and a movable frame is provided on the bracket, with the tray detachably disposed on the movable frame;

[0008] A driving device is disposed on the container, and the driving device is connected to the bracket through a transmission mechanism; the driving device is used to drive the transmission mechanism to move the moving frame on the bracket, so that the storage tank on the material tray can be automatically aligned with the feed port on the container in sequence.

[0009] Therefore, the feed inlet on the filling fixture is directly connected to the discharge equipment, which helps prevent workpieces from easily falling or being lost during the feeding process and effectively ensures that the feed is accurately guided to the storage trough of the material tray. The drive device is connected to the bracket through a transmission mechanism, so that the moving frame on the bracket can carry the material tray to move forward and backward, so that the storage trough on the material tray is automatically aligned with the feed inlet on the container in sequence, realizing the trough changing operation during the filling process.

[0010] The structure of the bracket is improved, comprising two side baffles and a sliding rod connecting the two side baffles. The movable frame is fitted onto the sliding rod and can move along the sliding rod between the two side baffles. Thus, the tray can be installed inside the movable frame, allowing the movable frame to carry the tray and move it horizontally within the bracket, so that the storage trough on the tray can automatically align with the feed inlet on the container, automatically completing the continuous filling of the storage trough on the tray.

[0011] In one embodiment, the container has a hollow mounting cavity and a guide post vertically arranged in the mounting cavity, and the bracket is disposed in the mounting cavity of the container; both sides of the bracket have guide holes and are sleeved with the guide post through the guide holes, so that the baffle can move up and down along the guide post, thereby enabling the entire bracket to move up and down in the mounting cavity through the baffles on both sides.

[0012] In one embodiment, the transmission mechanism includes a push block and two translation sliders that can be pushed by both ends of the push block. The push block is connected to the driving device, and both sides of the push block have first inclined surfaces. The bottom of both side plates of the bracket have protrusions, and the protrusions have second inclined surfaces. Both ends of the two translation sliders have third inclined surfaces that respectively match the shapes of the first and second inclined surfaces. Thus, when the driving device drives the push block to move in the height direction, the pushing action of the inclined surfaces causes the push block to push the translation sliders located at its two ends to the sides, thereby lifting the side plates and raising the entire bracket.

[0013] In one embodiment, the transmission mechanism further includes a drive slider connected to the output end of the drive device, the drive slider having triangular protrusions; a material support is provided on the moving frame, the bottom of the material support having multiple triangular grooves for the triangular protrusions to be inserted into and tracks located on both sides of the multiple triangular grooves, the multiple triangular grooves being arranged in an orderly manner along the length direction of the tracks on the bottom of the material support; the drive slider is mounted on the tracks and can move relative to the tracks; a vertically arranged sliding shaft is provided on the tracks, and a sliding hole for the sliding shaft to be inserted is also provided on the bottom of the material support. The tracks and the drive slider can float up and down at the bottom of the material support, allowing the triangular protrusions on the drive slider to be inserted into or disengaged from the triangular grooves, thus achieving positioning.

[0014] In one embodiment, the bottom of the movable frame has a toothed row composed of orderly arranged teeth, and the container has toothed grooves that mate and mesh with the teeth on the toothed row; wherein the toothed grooves are offset from the triangular grooves on the material support. Thus, when the movable frame moves the material tray to a certain position, the meshing of the teeth and toothed grooves automatically locks the moved position in preparation for the next movement, thereby achieving progressive displacement.

[0015] In one embodiment, the toothed grooves are all oblique triangular grooves inclined in a first direction, and the teeth on the toothed rack are matched with the shape of the toothed grooves; the toothed grooves have long inclined surfaces inclined in the first direction, and the teeth can slide into the bottom of the toothed grooves along the long inclined surfaces; wherein, the positional relationship between the triangular grooves and the triangular protrusions is set such that when the teeth are engaged with the toothed grooves, the top of the triangular protrusions is perpendicular to one side of the inclined surface of the triangular groove. Thus, the moving frame moves relative to the drive slider via the track at the bottom of the material tray. Each time a triangular protrusion on the drive slider is inserted into a triangular groove, the triangular protrusion slides along one side of the inclined surface of the triangular groove to the bottom of the groove and completes its positioning. During this process, the moving frame moves the material tray by one position.

[0016] The structure of the material tray is improved by adding a material ejection assembly for disassembling the material tray. This assembly includes an inner push plate inside the material tray and an outer push plate outside the material tray. A connecting shaft connects the inner and outer push plates, passing through the material tray. A spring is mounted on the connecting shaft, pressing against the outer wall of the material tray and the outer push plate. Thus, operating the material ejection assembly pushes the material tray out of the material tray, allowing for easy removal of the tray.

[0017] The structure of the material stopping device is improved. The container is also equipped with a counter and a material stopping device for stopping the feed. The material stopping device is electrically connected to the counter. The material stopping device includes an extruder and a pair of air bladders disposed on both sides of the feed inlet. The pair of air bladders have protrusions arranged facing each other. The extruder is used to squeeze the pair of air bladders to drive the protrusions on the pair of air bladders to move towards each other, thereby stopping the workpiece.

[0018] This application also provides a precision parts processing equipment, including a vibratory feeder, a conveyor track, a discharge bin, and a filling fixture. The vibratory feeder, the conveyor track, and the discharge bin are connected in sequence. The output end of the discharge bin is connected to the inlet of the container to ensure accurate feeding into the container and prevent workpieces from easily falling or being lost during the feeding process. Thus, by using the filling fixture to replace manual labor, workpieces can be automatically filled into each storage slot on the material tray.

[0019] The advantages of the precision parts processing equipment and its filling fixture provided in this application are as follows: Compared with the prior art, the processing equipment of this application can replace manual labor and automatically fill the various storage slots on the material tray with workpieces, thereby solving the problems of low efficiency in the filling operation of precision parts and the easy occurrence of accidents leading to product loss or damage. Specifically, the feed port on the filling fixture is used to directly connect with the discharge equipment, effectively preventing workpieces from easily falling or being lost during the feeding process, thus ensuring that the feed is accurately guided to the storage slots on the material tray.

[0020] In order to continuously fill the storage troughs on the material tray with workpieces, the filling fixture of this application is equipped with a driving device. The driving device is connected to the bracket in the container through a transmission mechanism. The driving transmission mechanism enables the moving frame on the bracket to carry the material tray and move on the bracket. At the same time, the storage troughs on the material tray can be automatically aligned with the feed inlet on the container in sequence, realizing automatic trough changing operation during the filling process, thereby automatically completing the automatic filling of the storage troughs on the entire material tray.

[0053] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0054] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0055] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0056] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0057] like Figure 1 As shown, the outer periphery of the circular micro-workpiece 500 needs to be inspected during the production process. Specifically, the workpiece 500 needs to be rotated, and its outer periphery observed using an electron microscope to confirm the presence of defects. For this purpose, a fixture is required, but the workpiece 500 needs to be pre-mounted within the fixture.

[0058] like Figure 2 As shown, the fixture is a tray 1 with a storage trough 11. Workpieces need to be filled into the storage trough 11 for batch rotation and inspection. Due to the small size of the products, it is difficult to fill them into the storage trough 11 on the tray 1. Currently, manual operation is commonly used, which is inefficient. Moreover, manual operation is prone to instability, especially during the filling process, where workpieces are easily bumped against the side wall of the storage trough, causing them to accidentally bounce and fall. It is evident that such tiny workpieces are difficult to find and are prone to damage upon impact after falling, resulting in a low yield rate.

[0059] Furthermore, if machining is used for filling, the current machining fixtures can only pour the workpiece into a designated storage slot because the material tray has multiple storage slots. Then, the discharge end must be manually adjusted to move the workpiece to the next storage slot for continued filling. Therefore, current machining equipment cannot achieve automatic continuous filling of multiple storage slots.

[0060] Therefore, this application provides a novel precision parts processing equipment and its filling fixture to solve the problems of low efficiency in the filling operation of precision parts and the easy occurrence of accidents leading to the loss or damage of workpieces; at the same time, it can also realize continuous filling of the storage tanks on the material tray, automatically complete the filling of each storage tank on the material tray, and improve the filling efficiency. It will now be described in detail.

[0061] Please see Figure 3 A precision parts processing equipment includes a vibratory feeder 100, a conveyor track 200, a discharge bin 300, and a filling fixture 400 of this application, all connected in sequence. The vibratory feeder 100 arranges the workpieces 500 in an orderly manner and outputs them to the discharge bin 300 via the conveyor track 200. The discharge bin 300 is vertically arranged and connected to the filling fixture 400, into which the workpieces 500 are poured.

[0062] Please refer to the following: Figure 4 and Figure 5 The filling fixture 400 of this application includes a tray 1, a container 2, a bracket 3, and a drive device 4.

[0063] like Figure 2 As shown, the material tray 1 is provided with multiple storage slots 11 for filling workpieces 500, and these multiple storage slots 11 are arranged side by side on the material tray 1. One side of each storage slot 11 in the material tray 1 is a blind opening, and the other side is an opening. A detachable baffle rod 12 is provided on the other side of the material tray 1 to open and close the opening on that side. In addition, as Figure 5 As shown, the bottom of each storage trough 11 in the material tray 1 is inclined towards the opening so that when the above-mentioned circular micro workpieces 500 are filled into the storage trough 11, they can roll to one side of the storage trough 11 and be arranged in an orderly manner.

[0064] Please refer to the following: Figure 4 , Figure 5 and Figure 6 The container 2 is preferably a rectangular box. The top of the container 2 is provided with a feed port 21. The feed port 21 is used to connect with the output end of the discharge bin 300 to ensure that the feed can be accurately introduced into the container 2, thereby preventing the workpiece 500 from falling or being lost during the feeding process.

[0065] The bracket 3 is installed inside the container 2. The bracket 3 is equipped with a movable frame 31. The material tray 1 is detachably installed on the movable frame 31. The movable frame 31 can carry the material tray 1 to move horizontally on the bracket 3 so that the storage tank 11 on the material tray 1 is automatically aligned with the feed port 21 on the container 2.

[0066] like Figure 5 and Figure 6 As shown, the drive device 4 is mounted on the container 2, and the drive device 4 is connected to the bracket 3 via the transmission mechanism 5. The drive device 4 is used to drive the transmission mechanism 5 to move the moving frame 31 on the bracket 3, so that the storage tank 11 on the material tray 1 can be automatically aligned with the feed inlet 21 on the container 2 in sequence.

[0067] Compared with the prior art, the precision parts processing equipment and its filling fixture 400 provided in this application can replace manual labor and automatically fill the workpiece 500 into each storage slot 11 on the material tray 1, thereby solving the problem of low efficiency in the filling operation of precision parts and the easy occurrence of accidents leading to product loss or damage.

[0068] The inlet 21 on the filling fixture 400 is used to directly connect with the discharge device such as the discharge bin 300 mentioned above, so as to prevent the workpiece 500 from falling or being lost during the feeding process, and effectively ensure that the feeding can be accurately guided to the storage tank 11 of the material tray 1, thereby improving the accuracy of filling the workpiece 500.

[0069] Compared with machining and filling in related technologies, in order to continuously fill the storage troughs 11 on the material tray 1 with workpieces 500, the filling fixture 400 of this application is provided with a driving device 4. The driving device 4 is connected to the bracket 3 in the container 2 through a transmission mechanism 5, so that the moving frame 31 on the bracket 3 can carry the material tray 1 and move on the bracket 3 through the driving transmission mechanism 5, and at the same time, the storage troughs 11 on the material tray 1 can be automatically aligned with the feed inlet 21 on the container 2 in sequence, realizing automatic trough changing operation during the filling process, automatically completing the automatic filling of the storage troughs 11 on the entire material tray 1, and effectively improving the filling rate of workpieces 500.

[0070] For the structure of bracket 3, please refer to the embodiments in this application. Figure 6 , Figure 7 and Figure 8 The bracket 3 includes two side baffles 32 and a sliding rod 33 connecting the two side baffles 32. The movable frame 31 is fitted onto the sliding rod 33 and can move along the sliding rod 33 between the two side baffles 32. The material tray 1 is installed inside the movable frame 31, allowing the movable frame 31 to carry the material tray 1 and move it horizontally within the bracket 3, so that the storage tank 11 on the material tray 1 can be automatically aligned with the feed inlet 21 on the container 2, and the continuous filling of the storage tank 11 on the material tray 1 can be automatically completed.

[0071] Please refer to the following: Figure 4 , Figure 7 and Figure 8 The container 2 has a hollow mounting cavity 20 and a guide post 22 located in the mounting cavity 20, which is vertically arranged in the mounting cavity 20. The feed inlet 21 is located at the top of the mounting cavity 20 and communicates with the mounting cavity 20. The drive device 4 is located at the bottom of the mounting cavity 20, and the output end 41 of the drive device 4 extends from bottom to top into the mounting cavity 20.

[0072] The bracket 3 is installed in the mounting cavity 20, and the mounting cavity 20 has reserved space for the bracket 3 to move up and down.

[0073] like Figure 7 , Figure 8 and Figure 9 As shown, guide holes 321 are provided on the baffles 32 on both sides of the bracket 3, and the baffles 32 are sleeved with the guide post 22 through the guide holes 321, so that the baffles 32 can move up and down along the guide post 22, thereby enabling the entire bracket 3 to move up and down in the mounting cavity 20 through the baffles 32 on both sides.

[0074] Please refer to the embodiments in this application as well. Figure 8 , Figure 9 and Figure 10 The transmission mechanism 5 includes a push block 51 and two translation sliders 52 that can be pushed by the two ends of the push block 51. The push block 51 is connected to the drive device 4, and the two sides of the push block 51 have a first inclined surface 511.

[0075] Both sides of the bracket 3 have protrusions 322 at their bottom, and each protrusion 322 has a second inclined surface 323. In this embodiment, as... Figure 7 As shown, the protrusion 322 extends downward from the bottom of the baffle 32, and the protrusions 322 on both sides of the baffle 32 have a second inclined surface 323 facing each other.

[0076] Both ends of the two translation sliders 52 have a third inclined surface 521, which is in shape to match the first inclined surface 511 and the second inclined surface 323 mentioned above.

[0077] Thus, the drive device 4 can drive the push block 51 to move in the height direction. During this process, by utilizing the abutting cooperation between the aforementioned inclined surfaces, the push block 51 pushes the translation sliders 52 on both sides outward, thereby causing the translation sliders 52 to lift the baffles 32 on both sides of the bracket 3, thereby raising the entire bracket 3.

[0078] Please refer to the embodiments in this application as well. Figure 10 , Figure 11 and Figure 12 The transmission mechanism 5 also includes a drive slider 53, which is connected to the output end 41 of the drive device 4. The drive slider 53 is provided with triangular protrusions 531. Figure 10 As shown, the drive slider 53 is positioned vertically overlapping the push block 51, and the push block 51 has a through hole 512 in the middle. The output end 41 of the drive device 4 passes through the through hole 512 on the push block 51 and is connected to the drive slider 53.

[0079] like Figure 11 and Figure 12As shown, the movable frame 31 is provided with a material support 6. The bottom of the material support 6 is provided with a plurality of triangular grooves 61 for the triangular protrusions 531 to be inserted and a track 62 located on both sides of the plurality of triangular grooves 61. The plurality of triangular grooves 61 are arranged in an orderly manner along the length direction of the track 62 at the bottom of the material support 6.

[0080] The drive slider 53 is mounted on the track 62 and can move relative to the track 62. The track 62 has multiple vertically arranged sliding shafts 621, and the bottom of the material support 6 has sliding holes 63 for the sliding shafts 621 to be inserted. The track 62 and the drive slider 53 can float up and down together at the bottom of the material support 6, allowing the triangular protrusions 531 on the drive slider 53 to engage or disengage from the triangular grooves 61 for positioning.

[0081] Thus, the movable frame 31 acts as a movable body, carrying the material tray 1 on the material support 6. The relative movement between the track 62 at the bottom of the material support 6 and the drive slider 53 allows the movable frame 31 to move in a directional manner when the triangular protrusion 531 engages with the triangular groove 61 at the bottom of the material support 6.

[0082] In this embodiment, as Figure 10 As shown, the drive device 4 is preferably a double-rod cylinder, and the output end 41 of the drive device 4 can extend and move bidirectionally on the drive device 4. The push block 51 is fixed to the body of the drive device 4 by fasteners such as screws. The output end 41 of the drive device 4 passes through the through hole 512 on the push block 51 and is fixedly connected to the drive slider 53. Thus, when the drive device 4 is operating, the output end 41 moves bidirectionally to lift the entire body of the drive device 4, thereby driving the push block 51 to move in the height direction, thereby pushing the translation sliders 52 on both sides. Then, the output end 41 of the drive device 4 pushes the drive slider 53 upward again, so that the triangular protrusion 531 on the drive slider 53 engages with the triangular groove 61 at the bottom of the material support 6.

[0083] In other embodiments (not shown in the figure), the driving device 4 can also be a two-stage cylinder. The output end 41 of the driving device 4 is further provided with a two-stage pusher (not shown in the figure). A push block 51 is disposed on the output end 41. The two-stage pusher inside the output end 41 passes through the through hole 512 on the push block 51 and connects to the driving slider 53. In this way, the two-stage driving effect of the push block 51 and the driving slider 53 is also achieved.

[0084] In the embodiments of this application, please refer to Figure 7 The bottom of the movable frame 31 has a toothed row 312 formed by the orderly arrangement of teeth 311. In this embodiment, the movable frame 31 is preferably a quadrilateral frame, and the toothed row 312 is respectively located on both sides of the bottom of the movable frame 31.

[0085] Please refer to the following in conjunction: Figure 13 and Figure 14 The container 2 has toothed grooves 23 inside that mate with and mesh with the teeth 311 on the toothed rack 312. The bottom surface of the mounting cavity 20 of the container 2 has two rows of toothed grooves 23 corresponding to the positions of the toothed rack 312. Please refer to [further details omitted]. Figure 15 , Figure 16 and Figure 17 Each toothed groove 23 is offset from each triangular groove 61 on the aforementioned material holder 6.

[0086] Thus, when the moving frame 31 moves the material tray 1 to a position, the moving position will be automatically locked by the meshing of the teeth 311 and the tooth groove 23 to prepare for the next displacement action, thereby realizing progressive displacement.

[0087] Please refer to the embodiments in this application as well. Figure 16 and Figure 17 The tooth grooves 23 are all oblique triangular grooves inclined towards the first direction F, and the teeth 311 on the tooth row 312 are shaped to fit the tooth grooves 23. Here, the first direction F can be understood as the direction opposite to the forward direction of the moving frame 31. Figure 17 and Figure 18 As shown, each tooth groove 23 has a long inclined surface 231 that is inclined towards the first direction F, so that the tooth 311 can slide into the bottom of the tooth groove 23 along the long inclined surface 231 to complete the meshing.

[0088] The preferred positional relationship between the triangular groove 61 and the triangular protrusion 531 is as follows: Figure 16 As shown, when tooth 311 meshes with tooth groove 23, the top P of triangular protrusion 531 is perpendicular to the inclined surface M on one side of triangular groove 61.

[0089] Therefore, as Figure 19 As shown, the moving frame 31 moves relative to the drive slider 53 via the track 62 at the bottom of the material tray 6. When the triangular protrusion 531 on the drive slider 53 is inserted into a triangular groove 61, the triangular protrusion 531 will slide along one side slope M of the triangular groove 61 to the bottom of the groove and complete the positioning. During this process, the moving frame 31 drives the material tray 1 to move one position.

[0090] Among them, such as Figure 17 and Figure 18 As shown, the length of the opening of the triangular groove 61 is L1, the length of the groove of the tooth groove 23 and the distance between the tooth groove 23 is L2, the length of the tooth 311 and the distance between the teeth 311 is L3, and their arrangement relationship is preferably 1 / 2 L1+L2=L3.

[0091] In this way, the tooth 311 can slide along the long inclined surface 231 of the tooth groove 23 into the bottom of the tooth groove 23, and then complete a positional movement, so that each storage tank 11 on the material tray 1 is automatically aligned with and moved away from the feed port 21 in sequence.

[0092] Specifically, please combine them together. Figure 8 and Figure 9 as well as Figures 16 to 19 The working principle of the automatic alignment between the material storage tank 11 and the inlet 21 of the material tray 1 to achieve the tank changing operation on the filling fixture 400 of this application is detailed as follows:

[0093] (1) The drive device 4 starts and drives the push block 51 to move upward. The first inclined surface 511 on both sides of the push block 51 and the third inclined surface 521 on both ends of the translation slider 52 push and cooperate, so that the translation slider 52 on both sides moves outward, thereby driving the translation slider 52 to push the baffles 32 on both sides of the bracket 3, so that the entire bracket 3 is lifted up, and the toothed row 312 at the bottom of the moving frame 31 separates from the toothed groove 23 on the container 2.

[0094] (2) After the bracket 3 is lifted, the sliding shaft 621 on the track 62 is inserted into the sliding hole 63 at the bottom of the material tray 6, so that the drive slider 53 and the track 62 are together against the bottom of the material tray 6, so that the triangular protrusion 531 on the drive slider 53 is embedded in a triangular groove 61 at the bottom of the material tray 6. During the process of the triangular protrusion 531 being embedded in a triangular groove 61, the top P of the triangular protrusion 531 slides along one side slope M of the triangular groove 61 to the bottom of the groove, so as to drive the drive slider 53 to move relative to the track 62, thereby causing the material tray 6 to move. In this way, the moving frame 31 carries the material tray 1 through the material tray 6 and moves it horizontally, so that a storage tank 11 on the material tray 1 is aligned with the inlet 21 of the container 2, so that the workpiece 500 can be filled into the aligned storage tank 11.

[0095] (3) After the filling of the storage tank 11 is completed, the drive device 4 drives the push block 51 to reset, thereby releasing the push on the bracket 3 and causing the bracket 3 to fall back. The triangular protrusion 531 on the drive slider 53 separates from the triangular groove 61 at the bottom of the material support 6, and at the same time, the teeth 311 at the bottom of the moving frame 31 gradually mesh with the tooth groove 23 of the container 2. During the meshing process, the teeth 311 slide along the long inclined surface 231 of the tooth groove 23 into the bottom of the tooth groove 23, so that the moving frame 31 drives the material support 6 to move one position, so that the storage tank 11 that has been filled on the material tray 1 is removed from the feed inlet 21. Then, the next storage tank 11 adjacent to it will move close to the feed inlet 21 so that when the drive device 4 is started again, the next storage tank 11 will move towards the feed inlet 21 and be aligned with the feed inlet 21.

[0096] (4) Repeat the above operation to achieve progressive displacement, so that the storage tank 11 on the material tray 1 is automatically aligned with the feed port 21 on the container 2.

[0097] As can be seen, the filling fixture 400 of this application has a compact structure. It only uses one drive device 4 to lift the bracket 3 and translate the moving frame 31, which effectively saves space and reduces the overall volume.

[0098] In the structure of the filling fixture 400, the push block 51 and translation slider 52 of the transmission mechanism 5 are used to push and cooperate with the baffles 32 on both sides of the bracket 3 so that the drive device 4 outputs in one direction, thereby lifting the entire bracket 3.

[0099] Then, by cleverly utilizing the track 62 between the drive slider 53 of the transmission mechanism 5 and the bottom of the material support 6, as well as the interlocking between the triangular protrusion 531 and the triangular groove 61, the first stage of position change is achieved, so that the storage tank 11 on the material tray 1 near the feed port 21 can be moved to the feed port 21 to complete the alignment.

[0100] The second stage of position change is achieved by using the teeth 311 at the bottom of the moving frame 31 to match the shape of the groove 23 in the container 2, so that the filled storage tank 11 is moved away from the feed inlet 21 and the adjacent storage tank 11 is brought closer to the feed inlet 21 for the next moving action.

[0101] Thus, the drive device 4 can drive the moving frame 31 to move progressively through the transmission mechanism 5 and the transmission connection with the bracket 3, so that the storage tank 11 on the material tray 1 can be automatically aligned with the feed port 21 in sequence, and automatically complete the tank changing operation of the storage tank 11 on the material tray 1.

[0102] Regarding the structure of the material tray 6, please refer to one embodiment of this application. Figure 11 and Figure 14 The material tray 6 is also equipped with a material ejection assembly 7 for easy disassembly of the material tray 1. The material ejection assembly 7 includes an inner push plate 71 disposed inside the material tray 6 and an outer push plate 72 disposed outside the material tray 6. A connecting shaft 73 connects the inner push plate 71 and the outer push plate 72, and the connecting shaft 73 passes through the material tray 6. A spring 74 is provided on the connecting shaft 73, and the spring 74 presses against the outer wall of the material tray 6 and the outer push plate 72.

[0103] Thus, by operating the unloading assembly 7, the material tray 1 can be pushed out of the material support 6, thereby easily removing the material tray 1. Specifically, manually pushing the outer push plate 72 will activate the inner push plate 71, pushing the material tray 1 installed in the material support 6 so that the material tray 1 can be smoothly removed from the opening on the other side of the material support 6. When the force applied by the hand is removed, the spring 74 will automatically reset the inner push plate 71 and the outer push plate 72 for the next operation.

[0104] In this embodiment, as Figure 11 As shown, a hook groove 64 for inserting a finger is provided on the opening on the other side of the material tray 6, allowing the finger to be directly inserted into the hook groove 64 to hook the material tray 1 out.

[0105] The above-mentioned grooving 64 operation and the material ejection component 7 operation can be used in combination according to the actual situation, so as to facilitate the removal of the material tray 1.

[0106] In addition, as mentioned above, such as Figure 2 As shown, a baffle rod 12 is provided on one side of the opening of the material tray 1. Therefore, as... Figure 11 As shown, the inner push plate 71 of the unloading assembly 7 is preferably provided with an avoidance groove 711 for the material stop rod 12 to be embedded, so that the inner push plate 71 and the material tray 1 fit more closely, thereby improving the structural compactness.

[0107] In one embodiment of this application, please refer to the following: Figure 20 and Figure 21 The container 2 is also equipped with a counter 24 and a material stop device 8 for stopping the feeding. The material stop device 8 is electrically connected to the counter 24 and is triggered according to a preset threshold on the counter 24 (such as calculating the number of workpieces 500 entering the container 2 from the feed port 21). The device blocks or allows workpieces 500 to enter the container 2 at the feed port 21, thereby achieving automatic material blocking when switching the storage tank 11 on the material tray 1, in order to cooperate with the above-mentioned tank changing operation of the material tray 1 and improve the filling efficiency of workpieces 500.

[0108] Please refer to the following: Figure 21 , Figure 22 and Figure 23 The material stopping device 8 includes an extruder 81 and a pair of air bladders 82 disposed on both sides of the feed inlet 21. Each pair of air bladders 82 has a protrusion 821, and the protrusions 821 on the pair of air bladders 82 are arranged facing each other. Figure 1 As shown, the container 2 is provided with a receiving chamber 25 located at the feed inlet 21. The extruder 81 and a pair of air bladders 82 are disposed in the receiving chamber 25. The receiving chamber 25 has opposing slots for the protrusions 821 on the pair of air bladders 82 to extend out and be disposed in opposite directions.

[0109] In this way, the workpiece 500 enters the container 2 between the protrusions 821. The protrusions 821 limit the feeding, so that the workpiece 500 can enter the container 2 in a uniform posture, which makes it convenient to fill the workpiece 500 into the storage tank 11 of the material tray 1 in an orderly manner.

[0110] like Figure 22 and Figure 23As shown, the extruder 81 is preferably a linear cylinder, and the output of the extruder 81 abuts against the air bladder 82. The extruder 81 is used to apply pressure to the pair of air bladders 82, so that the protrusions 821 on the pair of air bladders 82 deform and move towards each other to narrow the position between the two protrusions 821, thereby stopping the workpiece 500 and effectively avoiding hard contact between the workpiece 500 when stopping, which would damage the product quality.

[0111] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
