The lower guide block moving mechanism is located between the lower guide block and the lower part of the bagging bracket, and is used to drive the vertical and horizontal movement of the lower guide block. A guiding channel for the sample cup to enter the packaging bag is formed between the upper and lower guide blocks.

[0021] The beneficial effects of this invention are as follows: the cup body feeding assembly is installed between the injection molding machine and the sample cup assembly. After obtaining the sample cup body obtained by the injection molding machine, the cup body is transferred to the assembly assembly, thereby realizing the feeding of the cup body. During the feeding process, the lateral and vertical movement of the clamping jaws meets the clamping and conveying needs of the cup body. The cup body is placed on the assembly assembly by the up and down movement of the feeding jaws and the flipping in the vertical plane. The entire feeding process requires no direct human intervention. While achieving efficient feeding, sample cups can be directly retrieved from the injection molding machine. The cup cap feeding assembly, through the lifting unit, removes the cup caps from the cup cap box and conveys them upwards. During the upward conveying of the cup caps, the inclined lever acts as a stop, and the horizontal component of the lever's action pushes the cup caps laterally towards the cabinet until they are removed from the cabinet, thus enabling the individual retrieval of the cup caps. The lifting unit located in the window has an inclined lifting belt. Cup caps with their openings facing the lifting belt fall off on their own due to their center of gravity being away from the lifting belt, while cup caps with their openings facing away from the lifting belt move upwards close to the lifting belt, thus ensuring that the cup caps removed from the cabinet have a consistent posture. The cup caps removed from the cabinet enter the guide tube. Under the guidance and torsion of the guide tube, the cup caps are oriented downwards when they leave the guide tube, thus ensuring that the cup caps entering the feeding platform after leaving the guide tube maintain a consistent posture, thereby achieving precise and efficient feeding. The assembly integrates the detection component, the screwing component, and the bagging component, sequentially realizing the detection of the cup body, the screwing of the cup body and the cup lid, and the packaging of the sample cup, thus completing the assembly of the sample cup. The various processes of this invention are seamlessly connected, and each process is completed by automated equipment, resulting in high assembly efficiency. Attached Figure Description

Detailed Implementation

[0065] like Figures 1 to 40 As shown, the present invention includes an injection molding machine 18, a cup body feeding assembly 1, a cup lid feeding assembly 2, and an assembly assembly 10, as follows: Figure 8 As shown, the injection molding machine 18 is located in front of the cup body feeding assembly 1. The cup body feeding assembly 1 and the cup lid feeding assembly 2 are located on opposite sides of the assembly assembly 10. The cup body feeding assembly 1 feeds the cup body on one side of the assembly assembly 10, and the cup lid feeding assembly 2 feeds the cup lid on the opposite side of the assembly assembly 10. The structure and working principle of the present invention will be described below with reference to the accompanying drawings.

[0066] like Figures 1 to 7 As shown, the cup body feeding assembly 1 includes a clamping and conveying unit and a cup body feeding unit. The clamping and conveying unit is used to obtain the cup body of the sample cup from the injection molding machine 18, and the cup body feeding unit is used to transfer the cup body to the subsequent assembly assembly 10. The structure and working principle of the cup body feeding assembly 1 will be described in detail below with reference to the accompanying drawings.

[0067] like Figures 1 to 7 As shown, the cup feeding assembly 1 includes a clamping and conveying unit and a cup feeding unit, such as... Figure 1 , Figure 2 As shown, the clamping and conveying unit includes a horizontal guide rail bracket 11, a vertical guide rail bracket 13, a drive box 12, a conveying slide bar 14, and clamping jaws 151, as follows. Figure 7 As shown, the horizontal guide rail bracket 11 is placed laterally at the product discharge end of the injection molding machine 18. The drive box 12 is slidably mounted on the horizontal guide rail bracket 11, and the drive box 12 has a first drive mechanism that drives the drive box 12 to move laterally along the horizontal guide rail bracket 11. Specifically, as shown... Figure 1 As shown, the side wall of the horizontal guide rail bracket 11 has a conveying horizontal guide rail 111, and the drive box 12 is slidably connected to the conveying horizontal guide rail 111, thereby achieving a slidable connection with the horizontal guide rail bracket 11. Figure 4 As shown, the top of the horizontal guide rail bracket 11 has a conveying horizontal rack 112. The first drive mechanism includes a conveying horizontal motor and a conveying horizontal gear. The conveying horizontal motor is fixed inside the drive housing 12, and the conveying horizontal gear is fixed to the output end of the conveying horizontal motor and meshes with the conveying horizontal rack 112. When the conveying horizontal motor is working, it drives the conveying horizontal gear to rotate, which in turn moves along the conveying horizontal rack 112, thereby driving the drive housing 12, the vertical guide rail bracket 13, and the conveying slide bar 14 to move left and right. The gear and rack transmission mechanism is prior art and will not be described in detail.

[0068] The vertical guide rail bracket 13 is vertically arranged and fixed on the drive box 12. The conveying slide rod 14 is slidably arranged on the vertical guide rail bracket 13. The drive box has a second drive mechanism that drives the conveying slide rod 14 to move vertically along the vertical guide rail bracket 13. Specifically, the vertical guide rail bracket 13 has a conveying vertical guide rail 131, and the conveying slide rod 14 is slidably connected to the conveying vertical guide rail 131, thereby realizing the slidable connection between the conveying slide rod 14 and the vertical guide rail bracket 13. Figure 2 As shown, a conveying vertical rack 141 is fixed on the conveying slide 14. The second drive mechanism includes a conveying vertical motor and a conveying vertical gear. The conveying vertical motor is fixed inside the drive housing 12, and the conveying vertical gear is fixed at the output end of the conveying vertical motor and meshes with the conveying vertical rack 141. When the conveying vertical motor is working, it drives the rotation of the conveying vertical gear, which in turn drives the conveying vertical rack 141 to move up and down, thereby achieving the purpose of driving the conveying slide 14 to move up and down.

[0069] like Figure 1 As shown, a plurality of clamping jaws 151 are evenly arranged on the clamping jaw mounting member 15, and the clamping jaws 151 are located on the same straight line. In this embodiment of the invention, four clamping jaws 151 on the clamping jaw mounting member 15 are equally spaced. The clamping jaws 151 are pneumatic jaws, which clamp or release the cup body under the action of compressed air. The clamping jaw mounting member 15 is rotatably connected to the lower part of the conveying slide 14, and the conveying slide 14 has a third drive mechanism that drives the clamping jaw mounting member 15 to rotate.

The main body of the first tilting cylinder 142 is fixedly connected to the conveying slide bar 14, and the output shaft of the first tilting cylinder 142 is fixedly connected to the clamping jaw mounting member 15. The first tilting cylinder 142 drives the clamping jaw mounting member 15 to rotate in the vertical plane, and the clamping jaw mounting member 15 rotates 90 degrees for each action. The clamping jaw 151 is in the gripping position at the product discharge end of the injection molding machine 18 when it is in the position to grip the cup body. The clamping jaw 151 grips the cup body of the sample cup in the gripping position.

[0070] like Figure 1 , Figure 3As shown, the cup feeding unit includes a feeding bracket 16, a feeding slide rod 163, a feeding drive mechanism, a turntable 167, and a feeding gripper 17. The feeding bracket 16 is vertically arranged, and its bottom is a base 161, which is placed on the ground. The feeding slide rod 163 is slidably mounted on the feeding bracket 16, and the feeding drive mechanism is located between the feeding bracket 16 and the feeding slide rod 163 to drive the vertical movement of the feeding slide rod 163. Specifically, a feeding guide rail 162 is fixed to the side wall of the feeding bracket 16, and the feeding slide rod 163 is slidably connected to the feeding guide rail 162, thereby achieving a slidable connection between the feeding slide rod 163 and the feeding bracket 16. The feeding drive mechanism is a feeding cylinder 164. The cylinder barrel of the feeding cylinder 164 is fixedly connected to the base 161 at the bottom of the feeding bracket 16. A sliding rod fixing member 165 is fixed to the side wall of the feeding slide rod 163, and the piston rod of the feeding cylinder 164 is fixedly connected to the sliding rod fixing member 165. When the piston rod of the feeding cylinder 164 extends or retracts, it drives the sliding rod fixing member 165 to move up and down, thereby driving the feeding slide rod 163 to move up and down relative to the feeding bracket 16.

[0071] like Figure 8 As shown, the turntable 167 is rotatably connected to the upper part of the feeding slide 163, and the upper part of the feeding slide 163 has a fourth drive mechanism for driving the turntable 167 to rotate. Specifically, the fourth drive mechanism includes a second tilting cylinder 166, the body of which is fixedly connected to the upper part of the feeding slide 163, and the output shaft of which is fixedly connected to the turntable 167. When the second tilting cylinder 166 is activated, it drives the turntable 167 to rotate in the vertical plane, and the turntable 167 rotates 180 degrees each time. A plurality of feeding grippers 17 are evenly arranged on the feeding gripper mounting piece 169, and the plurality of feeding grippers 17 are located on the same straight line. The feeding gripper mounting piece 169 is fixedly connected to the turntable 167, specifically, as shown in the figure. Figure 5 , Figure 6 As shown, the turntable 167 and the loading gripper mounting part 169 are fixedly connected by a connector 168. One end of the connector 168 is fixedly connected to the edge of the turntable 167, and the other end of the connector 168 is fixedly connected to the loading gripper mounting part 169. When the second tilting cylinder 166 is activated, it drives the turntable 167 to rotate, which in turn drives the connector 168 and the loading gripper mounting part 169 to rotate, thereby realizing the tilting of the loading gripper 17. Figure 7 As shown, the cup feeding unit is located on the side close to the assembly assembly 10, i.e., the cup feeding station, and the cup feeding unit places the cup on the assembly assembly 10. The second tilting cylinder 166 drives the feeding gripper 17 toward the side where the clamping and conveying unit is located, and when the feeding gripper 17 is in a horizontal state, the feeding gripper 17 is in the transfer position of receiving the cup.

[0072] The working principle of the cup body feeding assembly 1 is described below:

[0073] (1) After the clamping jaws 151 of the clamping and conveying unit clamp the cup body at the product discharge end of the injection molding machine 18, as Figure 7 As shown, the first driving mechanism drives the clamping jaw 151 to move to the right, the second driving mechanism drives the clamping jaw 151 to move downward, and the third driving mechanism drives the clamping jaw 151 to be in a horizontal state until the clamping jaw 151 moves above the transfer position, at which time the cup body mouth is facing down. (2) The second driving mechanism drives the conveying slide bar 14 to move down, or the feeding driving mechanism drives the feeding jaw 17 to move up, until a part of the cup body extends into the feeding jaw 17, then the feeding jaw 17 clamps the cup body, and the clamping jaw 151 releases the cup body. (3) The clamping and conveying unit is reset until the clamping and conveying unit returns to the gripping position; the fourth driving mechanism of the cup body feeding unit drives the turntable 167 to rotate 180 degrees together with the feeding jaw 17 to achieve a flip, at which time the feeding jaw 17 is away from the clamping and conveying unit, and the cup body mouth is facing up. (4) The feeding gripper 17 is driven downward by the feeding drive mechanism until the cup body is lowered to the assembly station on the assembly assembly 10; then the assembly assembly 10 assembles the cup body and the cup body feeding unit is reset until the feeding gripper 17 returns to the transfer position.

[0074] The cup feeding assembly is installed between the injection molding machine 18 and the assembly assembly 10. After the cup body is processed by the injection molding machine 18, it is transferred to the assembly assembly 10, thus realizing the feeding of the cup body. During the feeding process, the lateral and vertical movement of the clamping jaws 151 meets the needs of clamping and conveying the cup body. The cup body is placed on the assembly assembly 10 by the up-and-down movement and vertical flipping of the feeding jaws 17. The entire feeding process does not require direct human intervention, achieving efficient feeding while allowing the sample cup body to be directly obtained from the injection molding machine 18.

[0075] like Figures 9 to 19 As shown, the cup lid feeding assembly 2 includes a cabinet 21, a cup lid box 22, a lifting unit 23, a guide pipe 24, and a cup lid feeding unit. The structure of the cup lid 28 to be fed in this invention is as follows: Figure 13 As shown, one end of the cup lid 28 is open, forming the lid opening. The structure and working principle of the cup lid feeding assembly 2 will be described in detail below with reference to the attached drawings. The cabinet 21 is the main structural component of the cup lid feeding assembly 2, constructed from welded profiles. The cabinet 21 is hollow internally, and one side of the cabinet 21 has a window 211. (See attached diagram.) Figure 11 As shown, the cup lid box 22 is located below the window 211 and is fixedly connected to the cabinet 21, as... Figure 10 As shown, the top surface and the side facing the cabinet 21 of the cup lid box 22 are open. In use, cup lids 28 are poured into the cup lid box 22.

[0076] like Figure 12As shown, the lifting unit 23 is a belt lifting mechanism comprising a lifting belt 231 and lifting rods 233. The lifting rods 233 are evenly distributed on the lifting belt 31, and the portion of the lifting belt 231 located within the window 211 is inclined. Specifically, the cup lid feeding unit 23 also includes four lifting rollers 232, which are located at the four vertices of a right-angled trapezoid and are located inside the lifting belt 231 and in contact with it. The cabinet 21 is also a right-angled trapezoidal structure, and the side of the cabinet where the cup lid box 22 is installed is an inclined surface, forming an acute angle with the vertical surface. Alternatively, there can be three lifting rollers 232, in which case the lifting rollers 232 are located at the three vertices of a triangle, and the three lifting rollers 232 are located inside the lifting belt 231 and in contact with it. The rotating lifting roller 232 drives the lifting belt 231 to move. When the lifting belt 231 moves, it moves upward within the window 211, which in turn moves the lifting rod 233 within the window 211 upward. As the lifting rod 233 moves upward, it pushes the cup lid 28, which is in contact with the upper edge of the lifting rod 233, upward. To allow the cup lids 28 in the cup lid box 22 to converge towards the side where the lifting belt 231 is located, so that they can be lifted by the lifting rod 233, the bottom of the cup lid box 22 is inclined, and the lower end of the bottom of the cup lid box 22 faces the side where the lifting belt 231 is located. Cup lids 28 in a vertical or nearly vertical position within the cup lid box 22 can be lifted by the lifting rod 233, such as... Figure 16 As shown, when the opening of the cup lid 28 faces away from the lifting belt 231, the center of gravity of the cup lid 28 is close to the lifting belt 231. At this time, the cup lid 28 is "sucked" by the lifting belt 231 and will not fall off the lifting rod 233. Figure 19 As shown, when the cup lid 28, lifted by the lifting rod 233, faces the lifting belt 231, the cup lid 28, whose center of gravity is located away from the lifting belt 231, falls off the lifting rod 233 under the influence of gravity. Therefore, the consistent posture of the cup lid 28 lifted by the lifting unit 23 can be ensured.

[0077] like Figure 9 , Figure 12 As shown, window 211 has an inclined lever 212, and the other side of cabinet 21 has a cup lid outlet 213 that communicates with window 211 and connects to the upper end of lever 212. The side where cup lid box 22 is located is adjacent to the other side where cup lid outlet 213 is located, as shown. Figure 15 As shown, during the movement of the lifting belt 231, the lifting rod 233 located inside the window 211 lifts the cup lid 28. After the cup lid 28 contacts the lever 212, the cup lid 28 moves along the lever 212 and exits the cabinet 21 through the cup lid outlet 213. Figure 14As shown, the distance between the lever 212 and the lifting belt 231 is greater than the width of the lifting rod 233, thereby avoiding interference between the lever 212 and the movement of the lifting rod 233. The distance between the lever 212 and the lifting belt 231 is less than the thickness of the cup lid 28, to ensure that the lever 212 can block the cup lid 28 and push the cup lid 28 to move along the tilt direction of the lever 212.

[0078] like Figure 9 , Figure 10 As shown, the upper inlet of the feed tube 24 is connected to the cup lid outlet 213. The lower part of the feed tube 24 is horizontally arranged, and a baffle 244 is provided at the lower outlet of the feed tube 24. The cup lid 28 is twisted in the middle of the feed tube 24 and faces downward when it reaches the lower outlet. Specifically, as shown... Figure 9 As shown, the guide tube 24 includes a vertical section 241 at the top, a torsion section 242 in the middle, and a horizontal section 243 at the bottom. The vertical section 241 is vertical, the torsion section 242 has a curved structure, and the horizontal section 243 is horizontal. When the cup lid 28 enters the vertical section 241 through the cup lid outlet 213, the cup lid 28 is vertical, and the opening of the cup lid faces away from the horizontal section. Under the action of gravity, the cup lid 28 slides along the vertical section 241 into the torsion section 242. During the sliding process in the torsion section 242, the cup lid 28 gradually twists, and the twisting trend is that the opening of the cup lid gradually faces downwards. Until the cup lid 28 moves into the horizontal section 243, the opening of the cup lid faces directly downwards. Therefore, the guide tube 24 is designed to both transfer the cup lid 28 out of the cabinet 21 and adjust the posture of the cup lid 28 so that the opening of the cup lid gradually faces downwards. Figure 10 As shown, the horizontal section 243 has a blocking cylinder 245. The piston rod of the blocking cylinder 245 has a stop block. When the stop block extends into the horizontal section 243 and contacts the cup lid 28, it prevents the cup lid 28 from sliding within the guide tube 24. Taking the side where the lower outlet of the guide tube 24 is located as the front end, when the first cup lid 28 at the front end contacts the baffle 244, the second cup lid 28 at the front end is located below the stop block. When the piston rod of the blocking cylinder 245 extends, causing the stop block to contact the cup lid 28, it prevents the cup lid 28 from moving forward. When the piston rod of the blocking cylinder 245 retracts, causing the stop block to separate from the cup lid 28, the cup lid 28 below the stop block moves forward under the push of the subsequent cup lid 28 until it contacts the baffle 244. The baffle 244 has an arc-shaped structure. Both ends of the baffle 244 are fixed in contact with the horizontal section 243, and the lower outlet faces the baffle 244. The baffle 244 is concentrically positioned with the cup lid slot located below the lower outlet. The cup lid 28, which is removed through the lower outlet, is blocked by the baffle 244, and when the cup lid 28 falls into the cup lid slot, it is concentric with the cup lid slot.

[0079] like Figure 9As shown, the cup lid feeding unit includes a support guide rail bracket 26, a feeding platform 25, and a cup lid feeding drive mechanism. The feeding platform 25 is located below the guide tube 24 and is slidably connected to the support guide rail bracket 26. The cup lid feeding drive mechanism is located between the feeding platform 25 and the support guide rail bracket 26 to drive the movement of the feeding platform 25. Specifically, the support guide rail bracket 26 has a support guide rail 261, as shown... Figure 9 As shown, the bottom of the loading platform 25 has two loading platform sliders 252. A support rail 261 is located between the two loading platform sliders 252 and is slidably connected to them, thus achieving a slidable connection between the loading platform 25 and the support rail 261. The cup lid loading drive mechanism is a cup lid loading cylinder 27. The side wall of the loading platform 25 has a loading platform mounting part 271. The cylinder of the cup lid loading cylinder 27 is fixedly connected to the support rail bracket 26, and the piston rod of the cup lid loading cylinder 27 is fixedly connected to the loading platform mounting part 271. When the piston rod of the cup lid loading cylinder 27 extends or retracts, it drives the loading platform 25 to reciprocate along the support rail bracket 26. Each time the cup lid loading cylinder 27 actuates, the loading platform 25 moves forward once along the support rail bracket 26. The cup lid feeding drive mechanism can also have other structures. For example, the cup lid feeding drive mechanism includes a cup lid feeding motor and a lead screw and nut assembly. The cup lid feeding motor is fixed on the support guide rail bracket 26. The lead screw of the lead screw and nut assembly is fixedly connected to the output shaft of the cup lid feeding motor, and the lead screw and nut of the lead screw and nut assembly are fixedly connected to the feeding platform mounting part 271 on the side wall of the feeding platform 25. The upper surface of the feeding platform 25 has a cup lid groove 251, such as... Figure 17 As shown, each time the loading platform 25 moves, a cup lid slot 251 is positioned below the lower outlet. Each time the cup lid loading cylinder 27 actuates, the loading platform 25 moves forward a fixed distance, equal to the distance between two adjacent cup lid slots 251. In this embodiment of the invention, as... Figure 18 As shown, there are four cup lid slots 251 on the loading platform 25. When cup lids 28 are placed in all the cup lid slots 251, the cup lids 28 on the loading platform 25 are removed. The cup lid loading drive mechanism drives the loading platform 25 to reset. At this time, the cup lid slot 251 at the front end of the loading platform 25 moves to the bottom of the lower outlet to receive cup lids 28 that have been moved out of the lower outlet again.

[0080] The working principle of the cup lid feeding assembly 2 is described below:

[0081] (1) Add cup lid 28 into cup lid box 22; (2) Start lifting unit 23. During the operation of lifting unit 23, lifting belt 231 moves and drives lifting rod 233 in window 211 to move upward, thereby lifting cup lid 28; (3) During the upward movement of cup lid 28, after cup lid 28 contacts lever 212, lever 212 generates lateral thrust on cup lid 28 until cup lid 28 is pushed out of cup lid outlet 213, and then cup lid 28 enters guide tube 24; (4) During the sliding process of cup lid 28 in guide tube 24, the posture is twisted. When cup lid 28 moves out of guide tube 24, cup lid opening of cup lid 28 faces downward; (5) Cup lid 28 that has moved out of guide tube 24 falls into cup lid groove 251. Blocking cylinder 245 pushes block into guide tube 24 to contact cup lid 28, blocking cup lid 28 from continuing to slide in guide tube 24. At this time, cup lid feeding drive mechanism (6) When the next cup lid slot 25 moves to the lower outlet of the guide tube 24, the piston rod of the blocking cylinder 245 retracts to release the cup lid 28. At this time, the cup lid 28 that was originally located below the blocking cylinder 245 moves to contact the baffle 244 and falls into the cup lid slot 251. Then the piston rod of the blocking cylinder 245 extends again to push the baffle into the guide tube 24 to block the cup lid 28 again. Then the blocking cylinder 245 blocks and releases the cup lid 28 one by one. (7) After all the cup lid slots 251 of the loading platform 25 are filled with cup lids 28, the cup lid loading drive mechanism pushes the loading platform 25 forward until all the cup lids 28 on the loading platform 25 are not blocked. At this time, the cup lids 28 can be taken from the loading platform 25 and transferred to the next process.

[0082] The cup lid feeding assembly 2, through the lifting unit 23, removes and upwardly conveys the cup lids 28 located in the cup lid box 22. During the upward conveying of the cup lids 28, the inclined lever 212 blocks the cup lids 28, and the horizontal component of the blocking force of the lever 212 pushes the cup lids 28 to move laterally toward the cabinet 21 until they are removed from the cabinet 21, thereby realizing the individual extraction of the cup lids 28. The lifting belt 231 of the lifting unit 23 located in the window 211 is inclined, with the cup lid opening facing the lifting belt 231. The cup lid 28 of 31 falls off by itself because its center of gravity is far away from the lifting belt 231. The cup lid 28 with its opening facing away from the lifting belt 231 moves upward close to the lifting belt 231, and then moves out of the cabinet 21 with the same posture. The cup lid 28 that moves out of the cabinet 21 enters the guide tube 24. Under the guidance and torsion of the guide tube 24, the cup lid 28 with its opening facing down when it moves out of the guide tube 24, thus ensuring that the cup lid 28 that moves out of the guide tube 24 and enters the loading platform 25 has the same posture again, thus achieving accurate and efficient loading of the cup lid 28.

[0083] like Figures 20 to 40As shown, the assembly assembly 10 includes an assembly bracket 9, an assembly table 93, a detection component, a screwing component 4, and a bagging component. The structure and working principle of the assembly assembly 10 will be described in detail below with reference to the accompanying drawings. Figures 20 to 40 As shown, the assembly table 93 is rotatably mounted on the assembly bracket 9, and the assembly table 93 rotates 90 degrees in each rotation. Specifically, as... Figure 21 As shown, the assembly platform 93 and the assembly bracket 9 are arranged vertically, with a bearing 91 between the assembly bracket 9 and the assembly platform 93. A rotating shaft 95 is fixed to the center of the assembly platform 93, passing through the bearing 91 and fixedly connected to the inner ring of the bearing 91. The lower part of the rotating shaft 95 is connected to the output shaft of the assembly motor 96, which drives the rotation of the rotating shaft 95. Each time the assembly motor 96 operates, it drives the rotating shaft 95 and the assembly platform 93 to rotate once, with a rotation angle of 90 degrees. To support and assemble the bearing 91, a bearing bracket 92 is provided between the bearing 91 and the assembly bracket 9.

[0084] like Figure 20 As shown, the assembly table 93 has four stations evenly arranged circumferentially. The four stations are a cup placement station, a cup inspection station, a cup lid placement station, and a packaging station. Each of the four stations has several cup slots 94. Thus, the assembly table 93 has a total of four sets of cup slots 94, which are evenly arranged circumferentially. Each set consists of multiple cup slots 94 evenly arranged along the same straight line.

[0085] The cup body feeding assembly 1 is located at the cup body placement station, where it places the cup body into the cup body slot 94. The cup body has a conical or cylindrical structure, with its bottom below the assembly table 93 and its mouth above the assembly table 93.

[0086] like Figure 20 As shown, the cup inspection station has inspection components, such as... Figure 22 , Figure 23As shown, the detection assembly includes a detection bracket 3 with a visual inspection head 35 positioned directly above the cup slot 94. The visual inspection head 35 performs quality inspection on the cup by acquiring an image of the cup, thus promptly identifying defective products. The number of visual inspection heads 35 can be equal to the number of cup slots 94 in each group, so that each cup slot 94 at the cup detection station has a visual inspection head 35 above it. In this way, a specific visual inspection head 35 is responsible for inspecting the quality of the cup within its corresponding cup slot 94. Alternatively, there can be only one visual inspection head 35. In this case, a detection drive unit is placed between the detection bracket 3 and the assembly bracket 9. The detection drive unit drives the detection bracket 3 to move along the arrangement direction of the cup slots 94 at the cup detection station, thereby sequentially inspecting the cups within each cup slot 94 at the cup detection station. The detection bracket 3 is slidably mounted on the top of the assembly bracket 9. Each time the detection drive unit moves, the distance the visual inspection head 35 moves is equal to the distance between two adjacent cup slots 94. Specifically, the detection drive unit includes a detection motor 32 and a lead screw 33. The detection bracket 3 has a "]" shaped structure, and the bottom of the detection bracket 3 has a detection bracket slider 31. The detection bracket slider 31 is slidably connected to the top of the assembly bracket 9. The detection motor 32 is fixed to the top of the assembly bracket 9. The arrangement direction of the lead screw 33 is parallel to the arrangement direction of the cup groove 94 of the cup detection station. The lead screw 33 is rotatably mounted on the top of the assembly bracket 9, and one end of the lead screw 33 is fixedly connected to the output shaft of the detection motor 32. The detection bracket slider 31 is threadedly connected to the lead screw 33. When the detection motor 32 is working, it drives the rotation of the lead screw 33, which in turn drives the detection bracket slider 31 to move along the assembly bracket 9, thereby realizing the movement of the detection bracket 3 relative to the assembly bracket 9.

[0087] The defective product in the cup is detected by the visual inspection head 35, and then removed. Figure 22 , Figure 23 As shown, the visual inspection head 35 is located on the inspection head mounting part 34, which is slidably connected to the upper part of the inspection bracket 3. The inspection bracket 3 has an inspection cylinder 36 that drives the inspection head mounting part 34 to reciprocate. The moving direction of the inspection head mounting part 34 is perpendicular to the arrangement direction of the cup grooves 94 in the cup inspection station. The inspection head mounting part 34 has a vertically arranged defective product picking cylinder 37. The piston rod of the defective product picking cylinder 37 has a defective product picking claw 38, which is a pneumatic claw. To facilitate the assembly of the defective product picking claw 38, the defective product picking claw 38 is fixed on the picking claw mounting part 39, and the picking claw mounting part 39 is fixedly connected to the piston rod of the defective product picking cylinder 37.

[0088] When the piston rod of the detection cylinder 36 is at the beginning of its stroke, the vision inspection head 35 is positioned above the cup body groove 94, and at this time, the vision inspection head 35 is in its working position. When the piston rod of the detection cylinder 36 is at the end of its stroke, the defective product pick-up gripper 38 is positioned above the cup body groove 94, and at this time, the defective product pick-up gripper 38 is in its working position. The detection cylinder 36, the detection head mounting part 34, the defective product pick-up cylinder 37, and the defective product pick-up gripper 38 constitute the defective product pick-up unit, which is used to remove the detected defective products.

[0089] The working principle of the detection component is described in detail below:

[0090] (1) The assembly table 93 rotates. When the cup moves to the bottom of the visual inspection head 35, the visual inspection head 35 acquires an image of the cup for quality inspection. (2) When there is only one visual inspection head 35, after each cup in the cup slot 94 is inspected, the inspection drive unit operates once, driving the inspection bracket 3 to move once, until the visual inspection head 35 moves to the top of the next cup slot 94. (3) When a defective product is detected, the inspection cylinder 36 and the defective product picking cylinder 37 operate, moving the defective product picking claw 38 to the defective product position, clamping the defective product through the defective product picking claw 38, and then the inspection cylinder 36 and the defective product picking cylinder 37 operate in reverse to remove and transfer the defective product. When the assembly table 93 rotates again, the cups inspected at the cup inspection station are rotated to the cup lid placement station.

[0091] The cup lid feeding assembly 2 is located at the cup lid placement station. At the cup lid placement station, the cup lid feeding assembly 2 places the cup lid 28 onto the assembly table 93. The cup lid placement station has a screwing assembly 4, which is used to screw the cup lid 28 and the cup body together to achieve the screwing assembly of the cup lid 28 and the cup body, thus obtaining the sample cup 19.

[0092] like Figures 24 to 28As shown, the screwing assembly 4 includes a lid-picking bracket 41, a lid-picking suction cup 48, a lid-moving mechanism, a screwing gripper 52, and a screwing drive unit. The lid-picking bracket 41 is fixed above the assembly bracket 9. Multiple lid-picking suction cups 48 are evenly arranged, with the number of cup-picking suction cups 48 equal to the number of cup body slots 94 in each group. The lid-moving mechanism is located between the lid-picking bracket 41 and the lid-picking suction cups 48, and is used to drive the lid-picking suction cups 48 to move between the lid-feeding position and the cup body slot 94 position. The lid-feeding position is located on the side away from the assembly table 93. When the lid-feeding suction cup 48 is located on the side of the lid-feeding position, it picks up the lid 28; then, under the action of the lid-moving mechanism, it moves the lid 28 to the side of the cup body slot 94. Specifically, the cup lid moving mechanism includes a cup lid picking horizontal cylinder 45, a cup lid picking plate 42, and a cup lid picking vertical cylinder 47. The cup lid picking plate 42 is slidably connected to the cup lid picking bracket 41. The cup lid picking horizontal cylinder 45 is located between the cup lid picking plate 42 and the cup lid picking bracket 41 and is used to drive the cup lid picking plate 42 to reciprocate. Multiple cup lid picking vertical cylinders 47 are evenly arranged and are vertically arranged at the bottom of the cup lid picking plate 42. The cup lid picking suction cup 48 is located on the piston rod of the cup lid picking vertical cylinder 47. The number of vertical cylinders 47 for picking up the cup lid is equal to the number of cup body slots 94 in each group. To achieve a sliding connection between the cup lid picking plate 42 and the cup lid picking bracket 41, a cup lid picking slider 44 is fixed to the top of the cup lid picking plate 42, and a cup lid picking guide rail 43 is fixed to the cup lid picking bracket 41. The cup lid picking guide rail 43 is slidably connected to the cup lid picking slider 44, thereby achieving a sliding connection between the cup lid picking plate 42 and the cup lid picking bracket 41. Figure 5 As shown, the piston rod of the cup lid picking cylinder 45 is fixedly connected to the picking plate mounting part 46 fixed on the top of the cup lid picking plate 42, thereby realizing the assembly of the cup lid picking cylinder 45 and the cup lid picking plate 42. Figure 26 As shown, the screw gripper 52 is located directly below the cup body groove 94 for gripping the cup body, and the screw drive unit is located between the screw gripper 52 and the assembly bracket 9 for driving the vertical movement and horizontal rotation of the screw gripper 52.

[0093] like Figures 26 to 28 As shown, the turning drive unit includes a vertical turning cylinder 54, a turning gear 55, a turning rack 53, and a horizontal turning cylinder 51, as follows: Figure 26 As shown, a screwing bracket 5 is fixed on the assembly bracket 9. The screwing bracket 5 is located between the assembly bracket 9 and the assembly table 93. A screwing rack 53 is slidably mounted on the screwing bracket 5. A screwing horizontal cylinder 51 is fixed on the screwing bracket 5 to drive the reciprocating movement of the screwing rack 53. A screwing gear 55 is rotatably mounted on the screwing bracket 5 and meshes with the screwing rack 53. A screwing vertical cylinder 54 is fixed on the screwing gear 55. A screwing gripper 52 is located on the piston rod of the screwing vertical cylinder 54. Figure 27 As shown, multiple rotating gears 55 are evenly spaced on the rotating bracket 5. The number of rotating gears 55 is equal to the number of cup body slots 94 in each group, and each rotating gear 55 corresponds to a cup body slot 94, with the rotating gear 55 located below the corresponding cup body slot 94. When the piston rod of the rotating horizontal cylinder 51 extends to drive the rotating rack 53 to move, the movement of the rotating rack 53 drives the rotation of the rotating gears 55, which in turn drives the rotation of the rotating vertical cylinder 54. When the rotating jaw 52 clamps the cup body, the rotation of the rotating vertical cylinder 54 drives the rotation of the rotating jaw 52 and the cup body, thereby screwing the cup body and the cup lid 28 together. At this time, to ensure the smooth screwing of the cup body and the cup lid 28, the cup lid pickup suction cup 48 picks up the cup lid 28 and places the cup lid 28 above the cup body in the cup body slot 94. Figure 28 As shown, when the piston rod of the rotary horizontal cylinder 51 extends or retracts, it drives the rotary gear 55 to rotate in both directions.

[0094] The working principle of the screwing assembly 4 is described below:

[0095] (1) The cup lid moving mechanism moves the cup lid picking suction cup 48 to the cup lid loading position. At this time, the cup lid picking suction cup 48 moves to the side away from the assembly table 93 and moves vertically downward until the cup lid picking suction cup 48 contacts the cup lid 28. The cup lid picking suction cup 48 then sucks up the cup lid 28 by negative pressure adsorption. (2) The cup lid moving mechanism reverses its action, causing the cup lid picking suction cup 48 to move to the side where the assembly table 93 is located until the cup lid 28 is moved to the cup body slot 94 position of the cup lid placement station on the assembly table 93. (3) The rotating drive unit operates. First, the piston rod of the rotating vertical cylinder 54 extends and pushes the rotating gripper 52 to move vertically upward until the rotating gripper 52 can clamp the cup body. Then, after the rotating gripper 52 clamps the cup body, The piston rod of the horizontal cylinder 51 extends to drive the rotating rack 53 to move, which in turn drives the rotating gear 55 to rotate, which in turn drives the vertical cylinder 54, the rotating gripper 52 and the cup body to rotate in the horizontal plane; when the cup body rotates in the horizontal plane, the cup lid 28 is screwed into the cup body under the action of the cup lid picking gripper; (4) after the cup lid 28 is screwed into the cup body, the rotating gripper 52 releases the cup body, the piston rod of the vertical cylinder 54 retracts back to its original position, the piston rod of the horizontal cylinder 51 retracts back to its original position, and waits for the next action command; (5) after the cup lid 28 is screwed into the cup body, the cup lid picking suction cup 48 releases the cup lid 28, and the cup lid moving mechanism moves the cup lid picking suction cup 48 to the cup lid feeding position, waiting to pick up the cup lid 28 that is fed again.

[0096] like Figure 20 As shown, the packaging station has a bagging assembly and a bag box 97, as... Figure 29As shown, the bagging assembly includes a sample cup pickup unit 7 and a packaging bag pickup unit 8. The sample cup pickup unit 7 includes a sample cup pickup bracket 62, a sample cup pickup suction cup 72, and a sample cup moving mechanism. The sample cup pickup bracket 62 is located above the assembly bracket 9. The sample cup pickup suction cup 72 is connected to the sample cup pickup bracket 62 through the sample cup moving mechanism. The sample cup moving mechanism is used to drive the sample cup pickup suction cup 72 to move between the cup body groove 94 and the opened packaging bag. Specifically, as... Figure 31 , Figure 32 As shown, the sample cup moving mechanism includes a sample cup rotating cylinder 71, a swing arm 73, and a sample cup picking cylinder 74. A sample cup picking bracket 62 is located above the assembly bracket 9. The sample cup rotating cylinder 71 is fixed to the sample cup picking bracket 62. One end of the swing arm 73 is fixedly connected to the output shaft of the sample cup rotating cylinder 71, and the sample cup picking cylinder 74 is fixed to the other end of the swing arm 73. The sample cup picking suction cup 72 is located on the piston rod of the sample cup picking cylinder 74. When the sample cup rotating cylinder 71 operates, it drives the swing arm 73 to rotate, as shown... Figure 33 As shown, with each action of the sample cup rotating cylinder 71, the swing arm 73 rotates by 90 degrees. When the swing arm 73 rotates to the horizontal position, the sample cup picking cylinder 74 is in the vertical position, and the piston rod of the sample cup picking cylinder 74 extends, causing the sample cup picking suction cup 72 to contact the cup lid 28 and adhere to the cup lid 28 by negative pressure adsorption. Subsequently, the sample cup rotating cylinder 71 reverses its action, driving the swing arm 73 to rotate in the opposite direction until the swing arm 73 returns to its initial vertical position. At this time, the sample cup picking cylinder 74 is in the horizontal position, and the sample cup 19 is in the bagging position.

[0097] like Figures 34 to 36 As shown, the packaging bag picking unit 8 includes a bag-covering bracket 81, an upper opening suction cup 87, and a lower opening suction cup 87'. The bag-covering bracket 81 is located above the assembly bracket 9, as shown. Figure 29 As shown, the bagging bracket 81 is directly or indirectly connected to the assembly bracket 9 via support legs 811. A bag box 97 is fixed to the support legs 811 of the bagging bracket 81, and a packaging bag 20 is placed inside the bag box 97. A packaging bag pickup unit 8 is located between the sample cup pickup unit 7 and the upper opening suction cup 87. An upper suction cup moving mechanism is located between the upper opening suction cup 87 and the upper part of the bagging bracket 81, which drives the vertical movement of the upper opening suction cup 87. Specifically, as... Figure 35 As shown, the upper suction cup moving mechanism includes an upper opening cylinder 84 and an upper suction cup fixing plate 86. The upper opening cylinder 84 is fixed to the top of the bag-covering bracket 81, and the upper suction cup fixing plate 86 is fixed to the piston rod of the upper opening cylinder 84. The upper opening suction cups 87 are evenly distributed at the bottom of the upper suction cup fixing plate 86. Figure 38As shown, the upper opening cylinder 84 is used to drive the upper suction cup fixing plate 86 to move vertically. A lower suction cup moving mechanism is located between the lower opening suction cup 87' and the lower part of the bag holder 81. This mechanism drives the lower opening suction cup 87' to move between directly below the upper opening suction cup 87 and the bag box 97. Specifically, as... Figure 35 As shown, the lower suction cup moving mechanism includes a lower opening vertical cylinder 84', a lower opening horizontal cylinder 88, and a lower suction cup fixing plate 86'. The lower opening horizontal cylinder 88 is fixedly connected to the support leg 811 through the opening cylinder mounting part 881, thereby realizing the fixed connection between the lower opening horizontal cylinder 88 and the lower part of the bag support 81. The lower opening vertical cylinder 84' is fixedly connected to the piston rod of the lower opening horizontal cylinder 88. The lower suction cup fixing plate 86' is fixedly connected to the piston rod of the lower opening vertical cylinder 84'. The lower opening suction cups 87' are evenly arranged on the top of the lower suction cup fixing plate 86'.

[0098] like Figure 38 As shown, the lower vertical cylinder 84' drives the lower suction cup fixing plate 86' to move vertically, and the lower horizontal cylinder 88 drives the lower suction cup fixing plate 86' to move laterally, and the lateral movement direction of the lower suction cup fixing plate 86' is perpendicular to the arrangement direction of the cup slots 94 in the packaging station. Figure 40 As shown, the upper and lower suction cups 87' adhere to the packaging bag 20 located between them, and work together to open the opening of the packaging bag 20. Specifically, as... Figure 39 As shown, the extension of the piston rods of the lower opening vertical cylinder 84' and the lower opening horizontal cylinder 88 moves the lower opening suction cup 87' to the bottom of the bag box 97. At this time, the lower opening suction cup 87' contacts the bottom of the packaging bag 20 inside the bag box 97. Then, the piston rods of the lower opening vertical cylinder 84' and the lower opening horizontal cylinder 88 retract to their original positions, moving the packaging bag 20 to the bagging position. The lower part of the bagging bracket 81 has a packaging bag support rod 812. When the packaging bag 20 moves to the bagging position, the packaging bag contacts the upper surface of the packaging bag support rod 812. When the packaging bag moves to the bagging position, the lower opening suction cup 87' is located inside the packaging bag support rod 812, and the lower opening suction cup 87' is flush with the upper surface of the packaging bag support rod 812. Subsequently, the piston rod of the upper-opening cylinder 84 extends, driving the upper-opening suction cup 87 to move vertically downwards until it contacts the top of the packaging bag 20. The upper-opening suction cup 87 then uses negative pressure to adhere to the packaging bag 20. Figure 40 As shown, the retraction of the piston rod of the upper opening cylinder 84 drives the upper opening suction cup 87 to move vertically upwards. This, in turn, causes the upper opening suction cup 87 and the lower opening suction cup 87' to work together to open the opening of the packaging bag 20. At this time, the sample cup picking cylinder 74 of the sample cup moving mechanism can move the sample cup 19 towards the side where the packaging bag 20 is located, as shown. Figure 40 As shown, insert the sample cup 19 into the opening of the packaging bag 20 until the sample cup 19 is moved into the packaging bag 20.

[0099] To ensure the sample cups are easily inserted into the packaging bag 20, as follows: Figure 34 As shown, a cup lid guide unit is provided between the upper suction cup moving mechanism and the sample cup picking unit 7. Figures 34 to 37 As shown, the cup lid guiding unit includes an upper guide block 85, a lower guide block 85', an upper guide block moving mechanism, and a lower guide block moving mechanism. The upper guide block 85 and the lower guide block 85' are arranged vertically and are located between the sample cup picking unit 7 and the upper suction cup moving mechanism. The upper guide block moving mechanism is located between the upper guide block 85 and the upper part of the bag holder 81, and is used to drive the vertical and horizontal movement of the upper guide block 85. The lower guide block moving mechanism is located between the lower guide block 85' and the lower part of the bag holder 81, and is used to drive the vertical and horizontal movement of the lower guide block 85'. A guiding channel for the sample cup 19 to enter the packaging bag 20 is formed between the upper guide block 85 and the lower guide block 85'. Specifically, the upper guide block 85 and the lower guide block 85' have the same structure; the lower surface of the upper guide block 85 has an arc surface, and the upper surface of the lower guide block 85' also has an arc surface. Figures 35 to 37 As shown, the upper guide block moving mechanism includes an upper guide vertical cylinder 82 and an upper guide horizontal cylinder 83. The upper guide vertical cylinder 82 is vertically arranged, and its cylinder barrel is fixedly connected to the top of the bag-covering bracket 81. The piston rod of the upper guide vertical cylinder 82 is fixedly connected to the cylinder barrel of the upper guide horizontal cylinder 83, and the piston rod of the upper guide horizontal cylinder 83 is fixedly connected to the upper guide block 85. The lower guide block moving mechanism includes a lower guide horizontal cylinder 83' and a lower guide vertical cylinder 82'. The lower guide vertical cylinder 82' is vertically arranged, and its cylinder barrel is fixedly connected to the lower part of the bag-covering bracket 81 through a guide cylinder mounting part 821. The piston rod of the lower guide vertical cylinder 82' is fixedly connected to the cylinder barrel of the lower guide horizontal cylinder 83', and the piston rod of the lower guide horizontal cylinder 83' is fixedly connected to the lower guide block 85'. The lower guide block 85' is positioned higher than the initial position of the lower opening suction cup 87', and the lower guide block 85' limits the lower edge of the packaging bag opening. After the upper opening suction cup 87 adheres to the packaging bag 20 and moves vertically upward to open the packaging bag 20 opening, the upper guide block 85 is located below the upper opening suction cup 87. Thus, the upper guide block 85 and the lower guide block 85' are located inside the packaging bag 20 opening.

[0100] like Figure 29 As shown, the bag box 97 has a rectangular parallelepiped structure and a placement cavity 98 inside. The bottom of the bag box 97 has a bottom hole 99 that communicates with the placement cavity 98. The bottom hole 99 is designed to facilitate the contact between the downward-opening suction cup 87' and the packaging bag 20 at the bottom of the placement cavity 98.

[0101] The number of sample cup picking cylinders 74, upper opening suction cups 87, and lower opening suction cups 87' can all be equal to the number of cup slots 51 in each group. In this embodiment of the invention, each group includes four cup slots 51, thus enabling the bagging of four sample cups 19 at a time. The number of sample cup picking cylinders 74, upper opening suction cups 87, and lower opening suction cups 87' can also be other than those in this embodiment of the invention. For example, in this embodiment, there are two sample cup picking cylinders 74, two upper opening suction cups 87, and two lower opening suction cups 87'. Figure 31 As shown, two sample cup rotary cylinders 71 are symmetrically arranged on the upper part of the sample cup pickup bracket 62, and a swing arm 73 is fixed on the output shaft of each sample cup rotary cylinder 71. Similarly, two sample cup pickup cylinders 74 are symmetrically arranged, and the cylinder barrels of the two sample cup pickup cylinders 74 are fixedly connected by a connecting rod 75. To facilitate the assembly of the sample cup pickup suction cup 72, a suction cup mounting part 741 is fixed on the piston rod of the sample cup pickup cylinder 74, and the sample cup pickup suction cup 72 is fixed on the suction cup mounting part 741. When two sample cup pickup cylinders 74, two upper opening suction cups 87, and two lower opening suction cups 87' are each provided, two sample cups 19 can be bagged at once. After packaging two sample cups 19, the bagging assembly should be moved along the arrangement direction of the cup body groove 51 to bag the other two sample cups 19. Therefore, as follows... Figure 29 As shown, the sample cup pickup bracket 62 and the bagging bracket 81 are both fixed on the bagging slide 6, as... Figure 30 As shown, the bottom of the bagging slide 6 is slidably connected to the feed guide rail 63, which is fixed to the assembly bracket 9. A feed cylinder 61 is provided between the bagging slide 6 and the assembly bracket 9. The feed cylinder 61 is used to drive the bagging slide 6 to move along the arrangement direction of the cup slots 51 in the packaging station, and the moving distance is equal to the distance between two adjacent cup slots 51. In this way, after the first and third sample cups 19 in the packaging station are bagged, the bagging slide 6 can be driven by the feed cylinder 61 to move, and the moving distance is equal to the distance between two adjacent cup slots 51. Then, the second and fourth sample cups 19 in the packaging station are bagged.

[0102] The working principle of the bagging assembly is described below:

[0103] (1) At the cup lid placement station, the cup lid 28 is assembled with the cup body to obtain the sample cup 19. The assembly table 93 continues to rotate 90 degrees to transfer the sample cup 19 to the packaging station; (2) The lower suction cup moving mechanism's lower opening horizontal cylinder 88 and lower opening vertical cylinder 84' move, as follows Figure 39As shown, the lower opening suction cup 87' is moved to the bottom of the bag box 97, so that the lower opening suction cup 87' contacts the bottom of the packaging bag 20 at the bottom of the placement cavity 98, and the packaging bag 20 is sucked by the lower opening suction cup 87'; (3) the lower suction cup moving mechanism is reset, and the packaging bag 20 is moved to the bagging position; (4) the piston rod of the upper opening cylinder 84 of the upper suction cup moving mechanism extends, so that the upper opening suction cup 87 contacts the top of the packaging bag 20, and the upper opening suction cup 87 sucks the packaging bag 20, as shown. Figure 40 As shown, the piston rod of the upper expansion cylinder 84 then retracts, opening the bag opening of the packaging bag 20; (5) the piston rod of the sample cup picking cylinder 74 of the sample cup picking unit 7 extends, pushing the sample cup 19 into the packaging bag 20, completing the bagging of the sample cup 19; (6) before the sample cup 19 enters the packaging bag 20, the upper guide block 85 and the lower guide block 85' are located between the packaging bag 20 and the sample cup 19. During the process of the sample cup 19 moving towards the bag opening of the packaging bag 20, the sample cup 19 enters between the upper guide block 85 and the lower guide block 85'. Since the upper guide block 85 contacts the upper edge of the bag opening of the packaging bag 20 and the lower guide block 85' contacts the lower edge of the bag opening of the packaging bag 20, the sample cup 19 can smoothly enter the bag opening of the packaging bag 20 through the upper guide block 85 and the lower guide block 85'.

[0104] The cup feeding assembly is installed between the injection molding machine and the sample cup assembly. After the sample cup body is obtained from the injection molding machine, it is transferred to the assembly assembly to realize the feeding of the cup body. During the feeding process, the lateral and vertical movement of the clamping jaws meets the needs of clamping and conveying the cup body. The cup body is placed on the assembly assembly by the up and down movement of the feeding jaws and the flipping in the vertical plane. The entire feeding process requires no direct human intervention. While achieving efficient feeding, sample cups can be directly retrieved from the injection molding machine. The cup cap feeding assembly, through the lifting unit, removes the cup caps from the cup cap box and conveys them upwards. During the upward conveying of the cup caps, the inclined lever acts as a stop, and the horizontal component of the lever's action pushes the cup caps laterally towards the cabinet until they are removed from the cabinet, thus enabling the individual retrieval of the cup caps. The lifting unit located in the window has an inclined lifting belt. Cup caps with their openings facing the lifting belt fall off on their own due to their center of gravity being away from the lifting belt, while cup caps with their openings facing away from the lifting belt move upwards close to the lifting belt, thus ensuring that the cup caps removed from the cabinet have a consistent posture. The cup caps removed from the cabinet enter the guide tube. Under the guidance and torsion of the guide tube, the cup caps are oriented downwards when they leave the guide tube, thus ensuring that the cup caps entering the feeding platform after leaving the guide tube maintain a consistent posture, thereby achieving precise and efficient feeding. The assembly assembly 10 integrates the detection component, the screwing component 4, and the bagging component, sequentially realizing the detection of the cup body, the screwing of the cup body and the cup lid 28, and the packaging of the sample cup 19 with the packaging bag 20, thus completing the assembly of the sample cup. The entire automated production line for sample cups integrates cup body injection molding, cup body feeding, cup body detection, the screwing of the cup body and the cup lid 28, and the packaging of the sample cup 19 with the packaging bag 20. Each process is connected and completed by automated equipment, and the cooperation between the processes achieves the packaging of the sample cups, greatly improving assembly efficiency compared to manual assembly methods.
