Description

Technical Field

[0001] The utility model belongs to the technical field of thermos cup processing automation, and in particular relates to a visual mouth-matching device for thermos cup processing. Background Art

[0002] In the production process of thermos cups, the matching of the inner liner and the outer shell is the first step in the welding process of the thermos cup. It mainly involves combining the inner liner and the outer shell and matching them together through pressure before welding them. Therefore, the matching of the inner liner and the outer shell is related to the yield rate of the subsequent welding of the thermos cup, and is also an important link in ensuring the quality of the finished product of the thermos cup welding.

[0003] Currently, the inner liner and the outer shell are mainly matched by manual matching or automated production matching. When manual matching is adopted, the matching degree of the inner liner and the outer shell is manually screened and tested before press-fitting. In this way, the matching yield of the thermos cup is relatively high, but the labor intensity of the workers is high, and the product efficiency and quality are easily affected by the workers' proficiency and fatigue. The labor cost is high and there is a risk of work-related accidents. When automated production matching is used, when the position of the inner liner and the outer shell placed by the robot deviates, directly press-fitting the inner liner and the outer shell without screening and testing for matching will cause the thermos cup to be scrapped, increase the production cost of the thermos cup, and affect production efficiency.

[0004] Therefore, in order to solve the problems of low production efficiency, unstable yield, and easy injury to personnel in the existing spouting process of thermos cups in the production process, it is urgent to propose a spouting equipment for thermos cups suitable for automated production to meet the existing thermos cup production needs of reducing production costs and improving production efficiency.

DETAILED DESCRIPTION

[0027] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, unless there is a conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0028] The present invention involves directional indications (such as up, down, etc.), relative to Figure 1 For example, upward on the horizontal paper is “up” and downward on the horizontal paper is “down”. If the specific posture changes, the directional indication will also change accordingly.

[0029] Combine Figure 1 As shown, the embodiment of the present invention provides a visual matching device for processing thermos cups, comprising a frame 1, a turntable mechanism 2 and a cup mold ejection mechanism 3 arranged on the frame 1, the turntable mechanism 2 comprising a rotary drive source 21 and a turntable 22 driven by the rotary drive source 21 to rotate intermittently, specifically, combined with Figure 7 As shown, the turntable mechanism 2 also includes a rotating bearing seat 23 fixed on the frame 1, a rotating bearing 24 arranged in the rotating bearing seat 23 and driven to rotate by the rotating drive source 21, the turntable 22 is connected to the end of the rotating bearing 24 and is driven to rotate by the rotating bearing 24. In this embodiment, the rotating drive source 21 adopts a motor, and the motor is connected to the controller; preferably, the rotating bearing seat 23 and the rotating bearing 24 are replaced by a cam divider, the rotating drive source 21 is connected to the input shaft of the cam divider, and the turntable 22 is connected to the output shaft of the cam divider. The rotating drive source 21 drives the cam divider to make the turntable 22 rotate intermittently. The frame 1 is provided with a pre-matching detection support frame 11 and a downward pressure support frame 12 in sequence according to the rotation direction of the turntable 22. The pre-matching detection support frame 11 is provided with a pre-matching detection mechanism 4 for detecting the gap between the inner liner and the outer shell of the thermos cup 37. The downward pressure support frame 12 is provided with a downward pressure mechanism 5 for press-fitting the inner liner and the outer shell of the thermos cup 37. The cup mold ejection mechanism 3 includes a cup mold 36 for fixing the thermos cup 37 and rotating with the turntable 22. The pre-matching detection mechanism 4 and the downward pressure mechanism 5 are both provided with a cup mold ejection mechanism 3. The pre-matching detection mechanism 4 includes a front detection camera 4 with a lens facing the corresponding cup mold ejection mechanism 3. 1. The pressing mechanism 5 includes a pressing driving source 51 provided on the pressing support frame 12, a pressing telescopic rod 52 which is driven by the pressing driving source 51 and can move up and down, a pressing guide assembly 53 which is provided on the pressing telescopic rod 52 and moves up and down with the pressing telescopic rod 52, and a pressing buffer assembly 54 which is provided at the end of the pressing guide assembly 53. Preferably, the pressing driving source 51 adopts a motor as a power source, and the pressing telescopic rod 52 adopts a screw rod. The motor transmits power to the screw rod through a transmission device (such as a coupling, a synchronous pulley or a gear), and the screw rod rotates and moves up and down. The use of a motor to drive the screw rod makes the control of the pressing distance more precise.

[0030] When the embodiment of the present utility model is in use, after the unloading robot places the thermos cup 37 to be fitted on the cup mold ejection mechanism 3 corresponding to the pre-fitting detection support frame 11, the pre-fitting detection mechanism 4 detects the fitting gap between the inner liner and the outer shell of the thermos cup 37 to be fitted. If the fitting gap detection fails, the pressing mechanism 5 does not perform press-fitting. Otherwise, the rotary drive source 21 drives the turntable 22 to rotate, causing the cup mold ejection mechanism 3 with the thermos cup 37 to be fitted placed on the turntable 22 to rotate to below the pressing mechanism 5 on the pressing support frame 12, and the pressing mechanism 5 performs press-fitting on the thermos cup 37. The embodiment of the utility model solves the problems of low production efficiency, unstable yield, and easy personnel injury in the existing fitting process of the thermos cup 37, thereby reducing production costs and improving production efficiency.

[0031] As a further preferred embodiment, the frame 1 is provided with a post-matching detection support frame 13 which is arranged behind the downward pressure support frame 12 according to the rotation direction of the turntable 22. The post-matching detection support frame 13 is provided with a post-matching detection mechanism 6 for detecting whether the inner liner and the outer shell of the thermos cup 37 are successfully matched. A cup mold pop-up mechanism 3 is correspondingly provided below the post-matching detection mechanism 6. The post-matching detection mechanism 6 includes a rear detection camera with a lens facing the corresponding cup mold pop-up mechanism 3.

[0032] In addition, this embodiment can also use a controller to connect the rotating drive source 21, the pre-matching detection mechanism 4, the pressing mechanism 5 and the post-matching detection mechanism 6 to the controller. The controller can be selected but not limited to a single-chip microcomputer or a microprocessor, and must include storage function and logical operation function. The pre-matching detection mechanism 4 sends the real-time detected matching gap information to the controller, and the controller controls the pressing mechanism 5 whether to press and match according to the received matching gap information. The post-matching detection mechanism 6 sends the real-time detected matching result information to the controller, and the controller controls the material picking robot to sort and pick up the thermos cup 37 according to the received matching result information.

[0033] It should be noted that when the cup mold ejection mechanisms 3 are grouped into three and are respectively arranged below the pre-matching detection mechanism 4, the downward pressure mechanism 5 and the post-matching detection mechanism 6, the rotary drive source 21 drives the turntable 22 to rotate 120 degrees each time; the cup mold ejection mechanisms 3 can also be arranged into a group of six, and every two cup mold ejection mechanisms 3 correspond to the pre-matching detection mechanism 4, the downward pressure mechanism 5 and the post-matching detection mechanism 6 respectively. At the same time, the pre-matching detection mechanism 4, the downward pressure mechanism 5 and the post-matching detection mechanism 6 are also arranged corresponding to the number of cup mold ejection mechanisms 3; the cup mold ejection mechanisms 3 can also be arranged into a group of eight. At this time, the rotary drive source 21 drives the turntable 22 to rotate 90 degrees each time. An empty position is set on the frame 1 for manual inspection of the thermos cup after press-matching, and every two cup mold ejection mechanisms 3 correspond to the pre-matching detection mechanism 4, the downward pressure mechanism 5, the post-matching detection mechanism 6 and the empty position respectively.

[0034] As a further preferred embodiment, the cup mold ejection mechanism 3 also includes an ejection collision plate 31, an ejection mounting shaft seat 32, a linear bearing 33, an ejection shaft 34 and a lifting spring 35. The ejection mounting shaft seat 32 is fixed on the turntable 22, and the upper end is connected to the lower end of the cup mold 36 through the lifting spring 35. The linear bearing 33 is arranged in the ejection mounting shaft seat 32. The lower part of the ejection shaft 34 can be slid up and down in the linear bearing 33, and the lower end is fixedly connected to the ejection collision plate 31. The upper end of the ejection shaft 34 is fixedly connected to the lower end of the cup mold 36. Preferably, the cup mold ejection corresponding to the downward pressing support frame 12 An impact buffer plate is provided on the frame 1 under the lifting mechanism 3. When the pressing mechanism 5 is pressed down, the pressing pressure compresses the lifting spring 35 and drives the elastic lifting shaft 34 downward. The elastic lifting collision plate 31 at the lower end of the elastic lifting shaft 34 contacts the impact buffer plate, avoiding the downward pressure applied by the pressing mechanism 5 to affect the turntable 22 and the elastic lifting mounting shaft seat 32, and preventing the turntable 22 and the elastic lifting mounting shaft seat 32 from deformation and damage; after pressing down, the single-acting cylinder 541 resets, and the lifting spring 35 lifts the cup mold 36, driving the elastic lifting shaft 34 upward, preventing the elastic lifting collision plate 31 from colliding with the impact buffer plate when the turntable 22 rotates.

[0035] As a further preferred embodiment, the downward pressing support frame 12 includes at least two downward pressing columns 121 arranged on the frame 1, a downward pressing top plate 122 connected to the upper ends of the at least two downward pressing columns 121, and a downward pressing partition 123 connected to the middle parts of the two downward pressing columns. The downward pressing guide assembly 53 includes a guide upper plate 531, a guide lower plate 532, and at least two guide rods 533 that can be slid up and down through the downward pressing partition 123 and are respectively connected to the guide upper plate 531 and the guide lower plate 532. The lower end of the downward pressing telescopic rod 52 is arranged on the guide upper plate 531. The downward pressing guide assembly 53 is used to ensure the downward pressing path of the downward pressing telescopic rod 52, prevent deviation during the downward pressing process, and avoid failure of the thermos cup 37 during press-fitting.

[0036] As a further preferred embodiment, the downward pressure buffer assembly 54 includes a single-acting cylinder 541 provided on the guide lower plate 532 and a press-fit mold 544 provided at the lower end of the telescopic rod of the single-acting cylinder 541. Preferably, the downward pressure buffer assembly 54 includes a downward pressure buffer shaft seat 542 provided on the guide lower plate 532 and a downward pressure buffer shaft sleeve 543 provided in the downward pressure buffer shaft seat 542. It should be noted that the downward pressure buffer shaft sleeve 543 can also be replaced by a linear bearing, and the telescopic rod of the single-acting cylinder 541 is provided in the downward pressure buffer shaft sleeve 543. The downward pressure buffer assembly 54 is used to alleviate the instantaneous impact on the thermos cup 37 when the downward pressure driving source 51 drives the downward telescopic rod 52 to press downward, so as to prevent the thermos cup 37 from being damaged and scrapped due to excessive downward pressure during press-fitting.

[0037] As a further preferred embodiment, the pre-matching detection mechanism 4 also includes a front detection screw module 42 provided on the pre-matching detection support frame 11 for adjusting the distance between the front detection camera 41 and the cup mold ejection mechanism 3. The front detection screw module 42 can be selected but not limited to a manual screw module or an electric screw module. The specific structure of the front detection screw module 42 is combined with the Figure 3 As shown, no further details will be given here, so that the cup mold pop-up mechanism 3 can place thermos cups 37 of different heights. It is also used to adjust the distance between the front detection camera 41 and the thermos cup 37, so that the front detection camera 41 can detect the gap between the inner liner and the outer shell of the thermos cup 37 more accurately.

[0038] As a further preferred embodiment, the post-matching detection mechanism 6 also includes a post-matching detection screw module provided on the post-matching detection support frame 13 for detecting the distance between the post-matching detection camera and the cup mold ejection mechanism 3. The post-matching detection screw module can be selected from, but not limited to, a manual screw module or an electric screw module, so that the cup mold ejection mechanism 3 can place thermos cups 37 of different heights. It is also used to adjust the distance between the post-matching detection camera and the thermos cup 37, so that the post-matching detection camera can detect the gap between the inner liner and the outer shell of the thermos cup 37 more accurately. The above description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein, and therefore, it should not be understood as limiting the scope of protection of the present invention.

[0039] In summary, although the present invention lists the above-mentioned preferred embodiments, it should be noted that although technicians in this field can make various changes and modifications, unless such changes and modifications deviate from the scope of the present invention, they should all be included in the protection scope of the present invention.
