Description

Technical Field

[0001] This utility model belongs to the field of wine box production technology, specifically relating to an automatic assembly system for wine box bases. Background Technology

[0002] Wine box production is a labor-intensive industry. Regarding the base installation, to match the speed requirements of the production line, the current line requires eight workers. Four of these workers hold the plastic base with their right hands, while each worker uses their right thumb, index, middle, and little fingers to press down on the four sides of the plastic base, ensuring the base is smaller than the box's dimensions. Then, the boxes produced in the previous process are transported to the manual pick-up position. The worker uses their left hand to pick up the box and their right hand to insert the plastic base into the bottom of the box and push it in. The box is placed in the standard position for the next production process. When the installed base box is transferred to the box plastic cover installation station, four other workers place the box upright on the production table. These four workers then use their right hands to pick up the plastic cover, tilt it at a 30° angle, and insert it into the box when it is two-thirds full. Then, they insert the plastic cover upright into the product box and fasten it to the base. The manual 30° tilt is to facilitate the insertion of the cover into the box. The base is locked to the box by the cover. Only then is the box base installation process completed. At the same time, the surface of the cover is also machined with a limiting groove for placing wine bottles. In summary, in the existing technology, the installation of the wine box base alone requires 8 workers. When the worker at the base picks up the base, pressing it down to fit it into the wine box requires a gripping force of 5 kg. Each worker must complete at least 3,000 repetitions per step, which is excessive labor intensity for the workers. When installing the plastic lid, the worker needs to tilt the box at a 30° angle. During the installation process, it is difficult to ensure that the tilt angle is consistent every time, often resulting in quality problems such as scratches, tears, and abrasions on the product. Moreover, when the base and lid are assembled, it means that the production of the wine box is nearing completion. At this point, problems with the plastic lid will render the entire wine box a defective product, resulting in a serious waste of production materials. In addition, the space occupied by 8 workers and corresponding equipment is enormous, which increases the production cost of the wine box. Utility Model Content

[0003] The purpose of this utility model is to solve the problems in the background technology and provide an automatic assembly system for wine box bases. This assembly system can continuously complete the assembly of the top cover and base of the wine box, which can greatly reduce the number of manual workers and reduce the labor intensity of manual workers.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] An automatic assembly system for wine box bases includes a frame, a four-station cam divider, box body molds, a top cover feeding mechanism, a box body pushing mechanism, a base clamping mechanism, and a finished product ejection mechanism. The four-station cam divider is installed in the middle of the frame, with its output shaft horizontally positioned. A turntable is mounted on the output shaft of the four-station cam divider.

A baffle is installed on the first guide rail to limit the position of the raw materials of the box on the box body conveyor belt. The first slide block is slidably installed on the first guide rail. The first servo conveying module is installed on one side of the first guide rail and connected to the first slide block. A material pusher plate adapted to the contour of the box is installed on the first slide block. The first servo conveying module drives the first slide block to push the box on the box body conveyor belt towards the box body mold along the first guide rail. A second sensor is installed on the baffle block to detect the box and control the start and stop of the box body conveyor belt.

[0008] The base clamping mechanism is installed above the turntable on the side opposite to the top cover feeding mechanism. The base clamping mechanism includes a bracket, a linear guide rail, a gripping cylinder, and a gripper mold. The bracket is installed on the frame of the base conveyor belt and the box body mold bracket. The linear guide rail is horizontally installed above the bracket and has a slider. The gripping cylinder is vertically installed above the slider. The gripper mold is slidably installed on the outer wall of the gripping cylinder and is connected to the bottom end of the piston rod of the gripping cylinder. The gripper mold is used to clamp the base and simultaneously apply a preload force to the insertion end of the base. A third sensor for detecting the base is installed on the base conveyor belt. The third sensor provides reference signals for the start and stop of the base conveyor belt and the clamping mechanism for clamping the base.

[0009] The gripper mold includes a gripper base, a gripping platform, a gripping cylinder, a cone, a spring push rod, and gripping plates. The gripper base is slidably mounted on the side wall of the gripping cylinder. The piston rod of the gripping cylinder is connected to the gripper base, and the gripping cylinder drives the gripper base to move up and down in the vertical direction. The gripping platform is fixedly connected to the bottom of the gripper base. A tapered hole with a larger top and a smaller bottom is machined on the gripping platform. The gripping cylinder is vertically mounted on the gripper base. The cone is connected to the extended end of the gripping cylinder and is pushed into the tapered hole by the gripping cylinder. The four gripping plates are evenly hinged on the outer side wall of the gripper base. A stepped hole is provided on the gripper base above the hinge point, connecting the gripping plates and the cone. The spring push rod is installed in the stepped hole. When the cone enters the tapered hole, it pushes the spring push rod to make the four gripping plates retract inward and clamp the base.

[0010] The finished product ejection mechanism is installed on the frame on the side opposite to the box pushing mechanism. The finished product ejection mechanism includes a second guide rail, a second slide block, a second servo conveying module, an ejection cylinder, an ejection suction cup, and an ejection pressure plate.

Groove. Detailed Implementation

[0028] like Figure 10 As shown, the wine box 100 in this embodiment is made of plastic. A limiting groove is machined on the inner wall of the lower part of the wine box 100. A support plate 201 is integrally formed on the top of the base 200. A limiting strip 202 that extends into the limiting groove is machined on the top of the support plate 201. During installation, the support plate 201 on the base 200 is closed so that the limiting strip 202 can extend into the wine box 100. At the same time, in order to prevent the limiting strip 202 from moving out of the limiting groove, the upper cover 300 is also connected to the base 200 and abuts against the support plate 201 to ensure the fixation of the base 200 and the wine box 100. In addition, the upper cover 300 is also machined with a groove 301 to accommodate the wine bottle.

[0029] like Figures 1 to 11As shown, the automatic assembly system for wine box bases provided in this embodiment includes a frame 1, a four-station cam divider 2, a box body mold 3, a top cover feeding mechanism 4, a box body pushing mechanism 5, a base clamping mechanism 6, and a finished product ejection mechanism 7. The four-station cam divider 2 is installed in the middle of the frame 1, and its output shaft is horizontally set. A turntable 21 is installed on the output shaft of the four-station cam divider 2. Four box body molds 3 are installed on the turntable 21 in a ring-shaped radiating pattern around the axis of the four-station cam divider 2. The box body molds 3 are adapted to the size and contour of the wine box 100. The box body molds 3 are hollow, and an air intake 31 is provided at one end of the box body mold away from the center. The four hollow box body molds 3 are connected to an air source through rotary joints. Pressure relief grooves 33 are machined on the side wall of the mold 3. The top cover feeding mechanism 4, the box body pushing mechanism 5, the base clamping mechanism 6, and the finished product ejection mechanism 7 are sequentially installed on the frame 1 corresponding to the position of the box body mold 3 along the rotation direction of the four-station cam divider 2. The top cover feeding mechanism 4, the box body pushing mechanism 5, the base clamping mechanism 6, and the finished product ejection mechanism 7 are respectively provided with a top cover conveyor belt 8, a box body conveyor belt 9, a base conveyor belt 10, and a finished product conveyor belt 11 on one side. During the process of the four-station cam divider 2 driving the turntable 21 to rotate, the top cover feeding mechanism 4, the box body pushing mechanism 5, the base clamping mechanism 6, and the finished product ejection mechanism 7 each complete one process of assembling the wine box base. When the turntable 21 rotates one revolution, the automatic assembly of the wine box base can be completed.

[0030] The upper cover feeding mechanism 4 is installed below the turntable 21, such as Figure 3 As shown, a boss 32 adapted to the contour of the top cover 300 is machined on the box body mold 3 outside the air intake 31. The boss 32 is adapted to the contour of the bottom of the bottle to improve the stability of the connection with the top cover 300. The top cover feeding mechanism 4 includes a dispensing cylinder 41 and a top cover cylinder 42. The top cover cylinder 42 is installed directly below the end of the lower box body mold 3. The piston rod of the top cover cylinder 42 is connected to a placement plate 43 that moves up and down toward the boss 32. The top cover conveyor belt 8 is located on one side of the top cover cylinder 42. The dispensing cylinder 41 is installed on the top cover conveyor belt 8 away from the top cover. On one side of the cover cylinder 42, the material dispensing cylinder 41 is horizontally set to push the cover 300 conveyed by the cover conveyor belt 8 to the shelf 43. The first sensor 44 for detecting the cover 300 is installed on the frame 1 on one side of the material dispensing cylinder 41. The first sensor 44 provides a start signal for the operation of the material dispensing cylinder 41 and the cover conveyor belt 8. After the cover 300 is pushed to the shelf 43, the cover cylinder 42 extends and pushes the cover 300 towards the upper box mold 3. After the cover 300 is attracted to the boss 32, the negative pressure sucks the cover 300 to the end of the box mold 3, completing the assembly of the cover 300.

[0031] The box-pushing mechanism 5 is mounted on the frame 1 on the rear side of the upper cover feeding mechanism 4 in the direction of rotation, such as... Figure 4 As shown, the box pushing mechanism 5 includes a first guide rail 51, a first slide block 52, and a first servo conveying module 53. The first guide rail 51 is located between the box body mold 3 and the box body conveyor belt 9 on one side of the turntable 21. A baffle 54 is installed on the first guide rail 51 to limit the position of the wine box 100 on the box body conveyor belt 9. The first slide block 52 is slidably installed on the first guide rail 51. The first servo conveying module 53 is installed on one side of the first guide rail 51 and connected to the first slide block 52. A material pusher 55 adapted to the contour of the wine box 100 is installed on the first slide block 52. The first servo conveying module 53 drives the first slide block 52 to push the wine box 100 on the box body conveyor belt 9 toward the box body mold 3 along the first guide rail 51. Under the action of the pressure relief groove 33, the speed of air discharge can be accelerated, so that the wine box 100 can be smoothly installed on the box body mold 3. A second sensor 56 is installed on the baffle block 54 to detect the wine box 100 and control the start and stop of the box body conveyor belt.

[0032] The base clamping mechanism 6 is installed above the turntable 21 on the side opposite to the upper cover feeding mechanism 4, such as Figure 5 As shown, the base clamping mechanism 6 includes a bracket 61, a linear guide rail 62, a gripping cylinder 64, and a gripper mold 65. The bracket 61 is mounted on the frame 1 between the base conveyor belt 10 and the box mold 3. The linear guide rail 62 is horizontally mounted above the bracket 61 and has a slider 63. The gripping cylinder 64 is vertically mounted above the slider 63. The gripper mold 65 is slidably mounted on the outer wall of the gripping cylinder 64 and is connected to the bottom end of the piston rod of the gripping cylinder 64. The gripper mold 65 is used to grip the base 200 and simultaneously apply a preload force to the insertion end of the base 200. The insertion end of the base 200 is one end of the support plate 201 on which the limiting strip 202 is mounted. A third sensor 66 for detecting the base 200 is mounted on the base conveyor belt 10. The third sensor 66 provides reference signals for the start and stop of the base conveyor belt 10 and for the base clamping mechanism 6 to grip the base 200. Figures 6-8As shown, the gripper mold 65 includes a gripper base 651, a gripping platform 652, a gripping cylinder 653, a cone 654, a spring push rod 655, and a clamping plate 656. The gripper base 651 is slidably mounted on the side wall of the gripping cylinder 64. The piston rod of the gripping cylinder 64 is connected to the gripper base 651, and the gripping cylinder 64 drives the gripper base 651 to move up and down in the vertical direction. The gripping platform 652 is fixedly connected to the bottom of the gripper base 651. A tapered hole 657, which is larger at the top and smaller at the bottom, is machined on the gripping platform 652. The gripping cylinder 653 is vertically mounted on the gripper base 651. The cone 654 is connected to the extended end of the gripping cylinder 653 and is pushed into the tapered hole 657 by the gripping cylinder 653. The four clamping plates 656 are evenly hinged on the outer wall of the clamping seat 651. The clamping seat 651 above the hinge is provided with a stepped hole 658 connecting the clamping plates 656 and the truncated cone 654. The large-diameter end of the stepped hole 658 faces the conical hole 657. The spring push rod 655 is installed in the stepped hole 658. When the truncated cone 654 enters the conical hole 657, the spring push rod 655 is pushed to make the four clamping plates 656 retract inward and clamp the base 200. When the base 200 is released, the clamping cylinder 653 drives the truncated cone 654 to move out of the conical hole 657. At this time, the spring push rod 655 retracts into the conical hole 657, the clamping plates 656 are not under force, and the stepped hole 658 can prevent the spring push rod 655 from falling off.

[0033] The finished product ejection mechanism 7 is mounted on the frame 1 on the side opposite to the box pushing mechanism 5, such as... Figure 9As shown, the finished product ejection mechanism 7 includes a second guide rail 71, a second slide block 72, a second servo conveying module 73, an ejection cylinder 74, an ejection suction cup 75, and an ejection pressure plate 76. The second guide rail 71 is horizontally installed between the box body mold 3 and the finished product conveyor belt 11 on the other side of the turntable 21. The second slide block 72 is slidably installed on the second guide rail 71. The second servo conveying module 73 is installed on one side of the second guide rail 71 and connected to the second slide block 72, driving the second slide block 72 to move on the second guide rail 71. The ejection cylinder 74 is vertically installed on the side wall of the second slide block 72 near the box body mold 3. The ejection suction cup 75 is horizontally installed on the piston rod of the ejection cylinder 74. The ejection pressure plate 76 is connected to the second slide block 72, and the end of the ejection pressure plate 76 is machined with a shape adapted to the contour of the bottom plate. The ejection plate 76 is positioned opposite the bottom of the wine box 100, and the ejection suction cup 75 is positioned opposite the side wall of the wine box 100. As the second servo conveying module 73 drives the second slide block 72 to move toward the box body mold 3, the ejection plate 76 sequentially pushes the base 200 into place and cooperates with the box body mold 3 to press the top cover 300 into place, completing the assembly of the base 200. Subsequently, the ejection suction cup 75 is attracted to the outer wall of the wine box 100 under the action of the ejection cylinder 74, and then the wine box 100 is dragged outward onto the finished product conveyor belt 11. To prevent the ejection suction cup 75 from being attracted to the box body mold 3, there are two pressure relief grooves 33, which are aligned with the attraction point of the ejection suction cup 75. This way, even when there is no wine box 100 on the box body mold 3, the finished product ejection mechanism 7 will not be attracted to the box body mold 3.

[0034] The method of using this utility model is as follows:

[0035] (1) First connect the power supply and air supply of the equipment. The rotary joint of the box body mold 3 needs to be connected to the negative pressure end of the compressor, and the rest of the pneumatic components are connected to the positive pressure end of the compressor.

[0036] (2) Then one worker puts the base 200 and the top cover 300 onto the corresponding top cover conveyor belt 8 and base conveyor belt 10. The wine box 100 is conveyed from the upstream wine box 100 production line.

[0037] (3) After the first sensor 44 of the upper cover feeding mechanism 4 detects the upper cover 300, the distributing cylinder 41 pushes the upper cover 300 to the placement plate 43 of the top cover cylinder 42. When the distributing cylinder 41 extends, the upper cover conveyor belt 8 stops working. After the distributing cylinder 41 retracts, the upper cover conveyor belt 8 moves the lower upper cover 300 to the extended end of the distributing cylinder 41 and then stops working. Then the top cover cylinder 42 drives the upper cover 300 to move toward the box body mold 3. After the top cover cylinder 42 moves into place, the protrusion 32 of the box body mold 3 extends into the groove of the upper cover 300. At the same time, the suction pipe is connected to the negative pressure pipe, adsorbing the upper cover 300 at the end of the box body mold 3. Then the top cover cylinder 42 resets and waits for the distributing cylinder 41 to push the next upper cover 300 to the placement plate 43.

[0038] (4) After the box body mold 3 adsorbs the top cover 300, the four-station cam divider 2 drives the box body mold 3 to adsorb the top cover 300 and rotate 90° clockwise, waiting for the wine box 100 processed by the upstream production line to be conveyed; at this time, the first servo conveying module 53 drives the first slide 52 to move to the end of the first guide rail 51 away from the box body mold 3, and the wine box 100 is conveyed to the baffle 54 along the box body conveyor belt 9. After the second sensor 56 detects the wine box 100, the box body conveyor belt 9 stops working. At the same time, the first servo conveying module 53 drives the first slide 52 to move upward towards the box body mold 3. At this time, the material pusher 55 on the first slide 52 pushes the wine box 100 towards the box body mold 3, so that the top cover 300 and the box body mold 3 enter the box body from the top of the wine box 100 in sequence. Then the first slide 52 drives the material pusher 55 to return to the original position, and the box body conveyor belt 9 continues to work, conveying the next wine box 100 to the baffle 54;

[0039] (5) When the second sensor 56 detects that the material push plate 55 on the first slide block 52 has been reset, the turntable 21 rotates 90° clockwise again. At this time, the base clamping mechanism 6 clamps a base 200 on the base conveyor belt 10 and installs it on the wine box 100. When the base 200 is clamped, the third sensor 66 detects the base 200, and the base conveyor belt 10 stops working. Then, the linear guide rail 62 drives the gripping cylinder 64 to move toward the base conveyor belt 10 through the slider 63. After it is in place, the gripping cylinder 64 drives the gripper mold. The clamping cylinder 65 moves towards the base 200, gripping the base 200 through the gripper mold 65. While gripping the base 200, the gripping cylinder 64 causes the clamping seat 651 to contact the upward-facing bottom surface of the base 200. Then, the gripping cylinder 653 extends, causing the cone 654 to extend into the conical hole 657 of the base 200. After the cone 654 enters the conical hole 657, it pushes the spring push rod 655 to extend outwards. When the spring push rod 655 extends, it causes the clamping plates 656 to rotate around the hinge. All four clamping plates 656 rotate simultaneously, causing the clamping seat... The clamping plate 656 below 651 closes to clamp the side wall of the base 200, while simultaneously pressing the facing support plate, causing the outward-protruding limiting strip on the support plate to retract, thus allowing the base 200 to smoothly extend into the wine box 100. After the gripper mold 65 grasps the base 200, the gripping cylinder 64 retracts, and the linear guide rail 62 drives the gripping cylinder 64 to move towards the box body mold 3. When the gripping cylinder 64 moves to the designated position, the base 200 is directly above the box body mold 3. Then, the gripping cylinder 64 extends and places the base 200 into the wine box 100. When the base 200 is inserted to 30% of its installation depth, the clamping cylinder 653 retracts. At this time, the spring push rod 655 is no longer squeezed by the cone 654 and retracts into the clamping seat 651. The clamping plate 656 releases the base 200. Then, the gripping cylinder 64 retracts and moves again above the base conveyor belt 10, waiting for the next base 200 to be clamped. The base 200 is installed to 30% to avoid the clamping plate 656 getting stuck on the wine box 100. At this time, the support plate and the limiting strip have already extended into the wine box 100. The base 200 can be installed in place by gently pushing it.

[0040] (6) After the base 200 is installed, the turntable 21 rotates 90° clockwise and moves to the finished product ejection mechanism 7. At this time, the second servo conveying module 73 drives the second slide 72 to move along the second guide rail 71 toward the box body mold 3. The ejection pressure plate 76 on the second slide 72 pushes the base 200 into place and then continues to move. It works with the box body mold 3 to install the top cover 300 on the base 200, thereby completing the final forming assembly of the base 200. Then the ejection cylinder 74 drives the ejection suction cup 75 to adhere to the outer wall of the wine box 100. Then the second servo conveying module 73 drives the second slide 72 to retract and remove the wine box 100 with the base 200 from the box body mold 3. The wine box 100 is then placed on the finished product conveyor belt 11 and conveyed to the next station.

[0041] Repeating the above steps can automatically and continuously complete the assembly of the base 200. At the finished product ejection mechanism 7, if there is no wine box 100, the ejection suction cup 75 will contact the pressure relief groove 33 of the box body mold 3 to prevent the ejection suction cup 75 from sticking to the box body mold 3, thus ensuring the stability of the assembly system. At the same time, the pressure relief groove 33 can expel the air inside the wine box 100 during the installation process, thereby improving the speed and stability of the wine box 100 assembly.
