[0002] In the production process of thermos cups, some of the accessories of thermos cups include cup lids, which are equipped with a plastic straw. Because the appearance of the cup lids is fashionable and strange, and in order to look good, there are no chamfers or arcs to guide the assembly at the assembly of the straw and the cup lid. It is difficult to align the insertion and it is not easy to make a mold to guide the insertion and pressing. Therefore, manual insertion and pressing with simple tooling is generally adopted. The simple tooling does not have a pressing force surface that fits the shape of the cup lid. It will tilt during insertion and needs to be manually straightened. The work intensity is high and the movements are complicated. Hold the cup lid in one hand and the straw in the other hand, align them visually, and put them into the tooling. Use the foot to step on the foot switch to control the downward pressure of the cylinder. Both hands need to straighten the cup lid and the straw during the whole process. If you are not careful, you may not be able to press it in or it may be bent and fail. This is more obvious with long straws. In addition, the foot switch is unsafe. In view of the above situation, it is urgent to design a device to improve working conditions, efficiency and quality. Summary of the invention

[0032] Example 1

[0033] Reference Figure 1-8 As shown in the illustration, in the thermos cup manufacturing industry, with the maturity of technologies such as robots, cost reduction has created conditions for popularization, which has greatly improved the degree of automation in the thermos cup manufacturing industry, achieved efficiency improvement by reducing manpower, reduced labor costs, and safeguarded the sustainable development of enterprises. In order to solve the problem of the existing production process requiring personnel to complete the installation between the thermos cup lid and the cup straw, and improve the accuracy and success rate of the installation, the bending of the cup straw caused by installation is greatly reduced, thereby improving the efficiency of assembly.

[0034] Therefore, the present embodiment proposes an automatic insertion and pressing device for cup lid straws, comprising a feeding unit 100, a picking unit 200, an insertion and pressing unit 300 and a cup mold unit 400, wherein the operation procedures are feeding, picking, raising the cup lid m, inserting and pressing, lowering the cup lid m, and picking up the cup lid m in sequence, and the above operations are repeated to realize the automatic assembly line installation of the straws s and the cup lid m, wherein the feeding unit 100 is used for stacking the straws s, the picking unit 200 is arranged at the next process of the feeding unit 100, and is used to take out the straws s in the feeding unit 100, and the insertion and pressing unit 300 is located above the cup mold unit 400. When the straw s is taken out of the workstation located in the insertion and pressing unit 300 and the insertion and pressing work is ready, the cup mold unit 400 is started, and the cup cover m located therein moves upward to the specified position, and the insertion and pressing unit 300 is pressed downward to press the straw s into the cup cover m to complete the installation, and then the insertion and pressing unit 300 is opened, and the cup mold unit 400 is lowered to take out the cup cover m with the straw s installed. In this embodiment, the cup mold unit 400 includes a cup mold 401 and a cup cover lifting assembly 402, and the cup cover m is set to limit the cup mold 401, and the cup cover lifting assembly 402 is located below the cup mold 401, which is used for the rise and fall of the cup cover m. It is not difficult to understand that the equipment should also include other auxiliary components required for automation, such as a workbench that provides a workstation, a controller that controls the lifting of the cylinder, and circuits for installing various electrical components, etc., which are not the technical problems to be solved by this embodiment, and can be implemented with reference to the prior art, and will not be described in detail in this embodiment.

[0035] Reference Figure 2 As shown in the figure, further, the loading unit 100 proposed in this embodiment includes an adjustable silo 101, a supporting assembly 102, a pushing assembly 103 and a detecting assembly 104. The straws s are stacked in the adjustable silo 101. The pushing assembly 103 is used to push the straws s from the adjustable silo 101 to the supporting assembly 102. The detecting assembly 104 is used to detect the straws s on the supporting assembly 102.

[0036] Specifically, the adjustable silo 101 also includes an inclined plate 101a, a baffle 101b, a gap 101c, an adjustment bracket 101d and a base 101e; wherein the inclined plate 101a is set at an inclination angle, and the straws s are stacked on the inclined plate 101a. Due to the force of gravity, they will have a tendency to move downward and be stacked, and the baffle 101b is set at a low position of the inclined plate 101a. The straws s are stacked on the inclined plate 101a and are blocked from sliding down due to gravity by the baffle 101b. The inclined plate 101a and the baffle 101b are spaced apart on both sides to form a gap 101c.

[0037] The adjustable silo 101 adopts an adjustable width silo to hold straws to accommodate straws s of different lengths. Specifically, a groove 101e-1 is set on the base 101e, and the adjusting bracket 101d is moved and installed on the base 101e through the groove 101e-1. The adjusting bracket 101d is installed with the groove 101e-1 by bolts, and can be moved in the groove 101e-1 and then fixed. The inclined plate 101a is set above the adjusting bracket 101d, and the space size of the gap 101c is adjusted by adjusting the movement of the adjusting bracket 101d, so as to realize the distance between the inclined plates 101a to accommodate straws of different lengths. In this embodiment, the detection component 104 can be a detection sensor, and the vertical and horizontal rotation, up and down movement, etc. can be achieved by a cylinder plus a screw structure.

[0038] Furthermore, the support assembly 102 includes a support plate 102a, a rolling surface 102b, a blocking portion 102c and a swing-angle bracket 102d, wherein the support plate 102a is arranged behind the baffle 101b, the rolling surface 102b is an inclined surface and is located at the top of the support plate 102a, the blocking portion 102c is arranged at the inclined low position of the rolling surface 102b, and is used to prevent the straw s from sliding down the rolling surface 102b, and the swing-angle bracket 102d and the outer axis of the blocking portion 102c are rotatably arranged. After being pushed out from the adjustable hopper 101, the straw s first contacts the top surface of the baffle 101b, and then rolls down from the rolling surface 102b to the blocking portion 102c due to gravity and hits the limit. After the secondary pushing is started, the straw s is pushed out higher than the blocking portion 102c. At this time, the straw s falls onto the swing angle bracket 102d. The swing angle bracket 102d in this embodiment also has an inclined surface, which is also for the effect of gravity falling.

[0039] In order to support the straw s, the swing bracket 102d has a hook 102e, and the straw s can be placed on the hook 102e for support. The swing bracket 102d is connected to the swing arm 102g through the shaft column 102f. The swing cylinder 102h can drive the hook 102e to swing by driving the swing arm 102g to move back and forth. The hook 102e is an arc, which is in contact with the outer surface of the straw s. More specifically, the hook 102e is located on the outside of the support plate 102a and is rotatably connected to the support plate 102a through the shaft column 102f. The hook 102e and the support plate 102a can rotate relative to each other, but the hook 102e and the shaft column 102f are fixed and cannot rotate relative to each other, and the swing arm 102g and the shaft column 102f cannot rotate relative to each other. The swing arm 102g and the hook 102e have a certain angle, and the swing arm 102g is hinged to the output shaft of the swing angle cylinder 102h. The forward and backward movement of the swing angle cylinder 102h pushes the swing arm 102g to rotate, thereby driving the rotation of the shaft column 102f, and then driving the hook 102e to swing in the vertical direction.

[0040] Furthermore, because the straws s are made of plastic and are light in weight, when the cylinder top is lifted to discharge the material, if the speed is slightly faster, multiple straws may be easily discharged, resulting in failure of material distribution. For this reason, the present embodiment adopts a two-stage mechanism for material distribution controlled by a cylinder, which can ensure successful material distribution. Specifically, the pushing assembly 103 is located as a whole in the gap between the two supporting plates 102a, and the pushing assembly 103 also includes a primary pushing plate 103a, a secondary pushing plate 103b and a support plate 103c. The primary pushing plate 103a and the secondary pushing plate 103b are arranged vertically front and back, and the two are connected by a horizontal support plate 103c, and the primary pushing plate 103a is located on the side of the baffle 101b, and the secondary pushing plate 103b is located on the side of the blocking portion 102c. It should be noted that a mounting plate is provided at the bottom of the pushing assembly 103, and two primary pushing plates 103a and two secondary pushing plates 103b are respectively vertically installed on the plate on the left and right, with a total of 4 columns. The upper support plate 103c is horizontally connected to form a frame, and a cylinder is provided at the bottom of the mounting plate, which drives the mounting plate to move up and down, thereby driving the primary pushing plate 103a and the secondary pushing plate 103b to move up and down, thereby pushing the straw s on the baffle 101b side and the straw s on the blocking part 102c side to ensure successful material distribution.

[0041] Reference Figure 3 As shown in the figure, in order to realize the grabbing of the straw s from the loading process to the insertion and pressing station, the material picking unit 200 in this embodiment includes a grabbing component 201 and a rotating component 202. The grabbing component 201 is used to grab the straw s of the supporting component 103, and the rotating component 202 is used to adjust the grabbed straw s from a parallel state to a vertical state.

[0042] More specifically, the grasping assembly 201 includes a clamping jaw 201a, a semi-arc portion 201b and a clamping cylinder 201c; the semi-arc portion 202b is arranged at the upper and lower parts of the clamping jaw 201a, the clamping cylinder 201c is connected to the clamping jaw 201a and drives the opening and closing of the two clamping jaws 201a, and the semi-arc portion 202b forms a clamping space 201d for clamping the straw s when it is closed; the rotating assembly 202 includes a first rotating shaft 202a, a first base 202b, a second rotating shaft 202c, and a second base 202d; the first rotating shaft 202a is arranged on the first base 202b and is connected to the clamping cylinder 201c, and can drive the clamping jaw 201a to rotate in the vertical direction through the rotation of the first rotating shaft 202a, and the second rotating shaft 202c is arranged on the second base 202d and is connected to the first base 202b, and can drive the first base 202b to rotate in the horizontal direction through the rotation of the second rotating shaft 202c.

[0043] Reference Figure 4-7, which shows the insertion and pressing unit 300 proposed in this embodiment. Specifically, the insertion and pressing unit 300 includes a pressing sleeve 301 and an opening and closing mold 302. The straw s in a vertical state can be moved to the bottom of the pressing sleeve 301 and the top of the opening and closing mold 302 by rotating the rotating assembly 202. The upper part of the straw s is limited by the pressing sleeve 301, and the lower part of the straw s falls into the opening and closing mold 302 for limitation. The cup cover m is arranged below the opening and closing mold 302. The pressing sleeve 301 can press the straw s into the cup cover m through the guidance of the opening and closing mold 302 by pressing downward.

[0044] It should be noted that the pressing sleeve 301 has a space inside to accommodate the straw s. When the straw s is clamped under the pressing sleeve 301, the pressing sleeve 301 descends to insert the straw s. The pressing sleeve 301 is lifted and lowered by a cylinder. Of course, it should also include a fixing method for the pressing sleeve 301 and a procedure for controlling the cylinder. These are not necessary technical features to be solved by this embodiment and can be easily implemented by referring to existing mature technologies, so they will not be described in detail here.

[0045] Furthermore, the opening and closing mold 302 includes a clamping block 302a, an introduction surface 302b, a tube insertion introduction part 302c and a plunger 302d; the two introduction surfaces 302b are relatively arranged on the clamping block 302a, and the clamping block 302a can drive the opening and closing of the introduction surface 302b and the tube insertion introduction part 302c through the plunger 302d. When the introduction surface 302b is closed, it forms an introduction channel 302e, and when the tube insertion introduction part 302c is closed, it forms an insertion port channel 302f. Due to the setting of the plunger 302d, the opening and closing degree of the clamp 302a can be controlled. There is a middle section between the introduction surface 302b and the insertion port introduction part 302c, which corresponds to the inner diameter of the straw s. The introduction surface 302b is a cone with an inner diameter gradually decreasing from top to bottom. The insertion port introduction part 302c corresponds to the inner diameter of the insertion port of the cup cover m. When half-open, the insertion port moves upward to the lower part of the middle section and stops. When closed, the insertion port introduction part 302c is wrapped around the periphery of the insertion port, that is, it is located in the insertion port channel 302f. At the same time, the straw s enters the middle section and the insertion port in turn from the introduction channel 302e. Finally, the straw s is fitted into the insertion port to complete the installation.

[0046] It should be noted that the insertion openings of the straw s and the cup cover m do not have chamfers or arcs for guiding assembly. In order to ensure reliable insertion and pressing, an opening and closing guiding mold is proposed, that is, the upper guiding device allows the straw s that has lost its clamping to accurately fall to the large inclined surface and then align with the mold under the joint action of the pressing sleeve 301, and the lower guiding device allows the straw assembly opening of the cup cover m to accurately align with the mold. In this way, under the guidance of the mold, the straw s can be accurately inserted and pressed onto the cup cover m, and at the same time the mold can be separated to facilitate the removal of the straw s.

[0047] The automatic working process of the equipment in this embodiment includes automatic material sorting, automatic material taking, and automatic insertion and pressing.

[0048] Automatic material sorting: The straw s is placed in a material storage with adjustable length. When the hook 102e is extended and is in the tube taking position and there is no straw s detected on the hook 102e, the three-axis cylinder drives the two-stage mechanism to sort the materials. The straw s goes from the material storage to the transfer position, and then to the hook 102e, and the material sorting is cyclic.

[0049] Automatic material picking: When the hook 102e is at the pipe picking position and a straw is detected on the tube rack, the picking and transplanting mechanism composed of two angle cylinders and an air clamp first clamps the straw s with the clamp 201a at the pipe picking position, and then controls the hook 102e to retract. After the hook 102e swings from horizontal to vertical, the small angle cylinder first drives the straw s to rotate 90 degrees to vertical, in preparation for insertion and pressing, and then the large angle cylinder rotates another 90 degrees to transplant the vertical straw s to the insertion and pressing position.

[0050] Automatic insertion and pressing: When the vertical guide is above the mold and the straight straw s is transported to the insertion and pressing station, the pressing sleeve 301 controlled by the servo motor through the ball screw and linear bearing quickly descends from the high position to the sleeve position, at which time it just covers the upper part of the straw s, and then the air clamp is released, and the straw s freely falls to the large slope above the mold. At this time, although the straw s is not clamped, it is still controlled, and the upper part is still covered in the pressing sleeve 301, and the lower part is automatically placed in the center of the cup cover m due to the center of gravity. When the cup cover m is installed in the cup mold and the start button is pressed, the cup The cover m rises through the cylinder below, and the outer wall of the tube insertion port of the cup cover m enters the lower guiding slope of the half-open mold. The half-opening ensures the reliability of the outer wall of the tube insertion port of the cup cover, while reducing the scratches on the outer wall and the wear of the rubber slope. In the next step, the mold is fully closed, and the pressing sleeve 301 descends slowly, and the straw s is pressed into the tube insertion port of the cup cover under the guidance of the mold. In the next step, the pressing sleeve 301 rises quickly, and the mold is half-opened again. The cup cover m with the straw s installed descends, and finally the mold is fully opened for easy removal. This cycle completes the automated installation.

[0051] Example 2

[0052] Based on the device proposed in the above embodiment, this embodiment proposes a method for automatically inserting and pressing a cup lid straw, which specifically includes the following steps:

[0053] S1: stacking the straws s in the adjustable silo 101;

[0054] S2: If the detection assembly 104 detects that there is no straw s on the swing bracket 102d, the primary push plate 103a rises to push the straw s out of the adjustable hopper 101 and onto the support plate 102a. After the straw s slides down the rolling surface 102b under the action of gravity and hits the blocking portion 102c, the secondary push plate 103b rises to push the straw s into the swing bracket 102d.

[0055] S3: When the detection assembly 104 detects the straw s, the clamping jaw 201a clamps the straw s, and the swing bracket 102d rotates downward and retracts, the first rotating shaft 202a drives the clamping jaw 201a to rotate to a vertical direction, and the horizontally rotating second rotating shaft 202c drives the straw s to rotate to the middle of the pressing sleeve 301 and the opening and closing mold 302;

[0056] S4: When the vertical straw s is transported to the insertion and pressing station, the pressing sleeve 301 quickly descends from a high position to cover the upper part of the straw s, the clamping jaws 201a are released, and the straw s freely descends into the introduction channel 302e and automatically falls on the center line of the cup cover m due to its center of gravity;

[0057] S5: The cup cover m is started to rise, and the outer wall of the tube insertion port enters the half-open tube insertion port channel 302f. After the tube insertion port channel 302f is completely entered, it is closed, and the tube insertion port is positioned in the tube insertion port channel 302f. The pressing sleeve 301 is slowly lowered, and the straw s is pressed into the tube insertion port under the guidance of the opening and closing mold 302;

[0058] S6: After the pressing is completed, the pressing sleeve 301 rises quickly, the opening and closing mold 302 is half-opened again, the cup cover m with the straw s installed descends, and finally the opening and closing mold 302 is fully opened to take away the cup cover m.

[0059] This method has a high degree of automation, reliable operation, and up-to-standard quality. It provides guidance for similar assemblies and lays the foundation for fully automatic insertion and pressure straw production lines in future unmanned factories. The equipment was a great success during the experiment, with stable pipe distribution and a 100% success rate in insertion and pressure. Originally, there was concern that the insertion and pressure might not be able to be inserted because the insertion openings of the straw s and the cup cover m did not have chamfers or arcs to guide the assembly. If necessary, the mold of the cup cover m needed to be modified to solve the problem. Therefore, there was no need to increase the chamfer at the insertion opening.
