Description

Technical Field

[0001] The utility model relates to the field of silicone pad assembly, and particularly relates to a silicone pad positioning and assembly device. Background Art

[0002] At present, in the production and manufacturing process of blood glucose meters, as one of the key components, the assembly quality of silicone pads directly affects the sealing performance, stability and user experience of blood glucose meters. However, most current blood glucose meter manufacturers still rely on traditional manual assembly methods in the assembly process of silicone pads. The existing manual assembly method requires the operator to first fix the connecting seat, and then precisely embed the two ear seats of the silicone pad into the corresponding slots of the connecting seat one by one. This process is not only cumbersome, with extremely high requirements for the operator's skills and concentration, but also due to the existence of human factors, such as improper operation, fatigue, etc., often leads to low assembly efficiency and difficult improvement in production capacity. In addition, after manual assembly, it usually depends on the operator's experience and visual inspection to judge whether the silicone pad is installed in place, whether there are misalignments, missing installations and other defective conditions. And this manual quality inspection method not only has low efficiency, but also has great subjectivity and misjudgment rate, making it difficult to ensure the stability and consistency of product quality.

[0003] With the intensification of market competition and the continuous improvement of consumers' requirements for product quality, the traditional manual assembly method has been difficult to meet the needs of blood glucose meter manufacturers.

[0031] The features of the present utility model and other related features are further described in detail below through embodiments for the understanding of those skilled in the same industry:

[0032] As Figures 1 to 10 shown, a silica gel pad positioning and assembling device includes: a device body 100, the device body 100 is provided with a silica gel pad loading station 1, a turntable 2 arranged on one side of the silica gel pad loading station 1, and a manipulator 3 for transporting the silica gel pad 201 from the silica gel pad loading station 1 to the turntable 2. One or more transport carriers 21 with connecting seats 202 placed thereon by external equipment are arranged on the turntable 2. Along the running direction of the turntable 2, there are successively arranged the silica gel pad loading station 1, a first vision positioning mechanism 4 for top vision positioning of the connecting seat 202 on the transport carrier 21 downward, and a first vision detection mechanism 5 for detecting whether the silica gel pad is assembled in place after assembly; the manipulator 3 is used to transport the silica gel pad from the silica gel pad loading station 1 to the transport carrier 21 and assemble the silica gel pad 201 into the connecting seat 202.

[0033] As described above, in this case, by setting the manipulator 3 and the turntable 2, the whole process of the silicone pad 201 from feeding, transporting to assembling is automated, greatly reducing the tediousness of manual operation and the time cost, significantly improving the assembling efficiency and the overall production capacity, so as to improve the production efficiency and competitiveness. Specifically, by the combined use of the manipulator 3 and the first vision positioning mechanism 4, it can ensure that the silicone pad 201 is accurately embedded into the corresponding slot of the connecting seat 202, realizing the high-precision positioning and assembling ability, reducing problems such as misalignment and missing assembly caused by human factors, improving the assembling precision and consistency of the product, and helping to improve the product quality and customer satisfaction. Through the setting of the first vision detection mechanism 5, it can automatically detect whether the silicone pad is assembled in place after the assembly is completed, replacing the traditional manual visual inspection method, improving the detection efficiency and ensuring the stability and reliability of the product quality.

[0034] As Figure 1 and Figure 2 shown, on one side of the silicone pad feeding station 1, there is a second vision positioning mechanism 6 for visually positioning the bottom of the silicone pad upward when the manipulator sucks the silicone pad and passes above it. In specific implementation, the first vision positioning mechanism 4, the second vision positioning mechanism 6, and the first vision detection mechanism 5 all include a CCD camera module and a light source module. Thus, through the setting of the second vision positioning mechanism 6, the silicone pad can be accurately visually positioned before being sucked by the manipulator and during the transportation process, and it can cooperate with the first vision positioning mechanism 4 to visually position the top of the connecting seat 202, realizing the precise alignment of the silicone pad and the connecting seat in three-dimensional space, greatly improving the assembling precision and success rate.

[0035] As Figure 1 and Figure 2 shown, directly in front of the silicone pad feeding station 1, there is also a second vision detection mechanism 7 for detecting the silicone pad. In specific implementation, the second vision detection mechanism 7 can be a 3D line laser measuring instrument capable of detecting depressions, scratches or other defects of the silicone pad. Thus, through the setting of the second vision detection structure, quality inspection can be carried out before the silicone pad is sucked by the manipulator 3 and assembled into the connecting seat 202, and depressions, scratches or other defects existing in the silicone pad itself can be found in time, which helps to avoid bringing unqualified silicone pads into the subsequent assembly process, thereby improving the qualification rate and quality stability of the overall product.

[0036] As Figure 3 and Figure 4As shown, in a specific implementation, the manipulator 3 is provided with a plurality of grippers 31, each gripper 31 is equipped with a first suction block 311 for adsorbing the front half of the silicone pad 201, a second suction block 312 for adsorbing the rear half of the silicone pad 201, and a pressing head 313 that can be extended and retracted up and down and is used to press the silicone pad 201 downward into the connecting seat 202, the first suction block 311 is recessed with a plurality of suction holes 3110 that cooperate with a plurality of protrusions on the silicone pad, and the second suction block 312 is provided with a through hole 3120 for the pressing head 313 to pass through and retract.

[0037] As described above, the arrangement of multiple grippers 31 allows the manipulator to transport multiple silicone pads at one time and assemble multiple silicone pads into the connecting seat at one time, significantly improving the efficiency and production capacity of the automated production line. The arrangement of the first suction block 311, the second suction block 312 and the multiple suction holes 3110 of the first suction block 311 of the gripper 31 can respectively absorb the front half and the rear half of the silicone pad 201 through the first suction block 311 and the second suction block 312, and the multiple suction holes 3110 provided in the recessed position are closely matched with the protrusions on the silicone pad, thereby ensuring the stability and accuracy of the silicone pad during movement and positioning, so as to reduce the displacement and shaking of the silicone pad during grasping and transportation, and improve the assembly accuracy. The arrangement of the pressure head 313 and the through hole 3120 allows the pressure head 313 to be retracted into the channel of the pressure head 313 when the second suction block 312 absorbs the silicone pad, without hindering the absorption; and when assembly is required, the pressure head 313 can be extended to directly press down the absorbed silicone pad, making full use of the space of the second suction block, so that the overall structure of the gripper 31 is more compact. In addition, since the position of the silicone pad has been precisely aligned through the adsorption process, the pressure head does not need to be realigned, making the pressing action have the ability to respond instantly, greatly shortening the assembly time and improving the overall efficiency of the production line.

[0038] like Figure 5 As shown, in a specific implementation, the device body 100 is also provided with a silicone pad positioning and conveying mechanism 8 for laterally conveying the silicone pad from the previous external station to the silicone pad loading station 1; the silicone pad positioning and conveying mechanism 8 includes: a first X-axis linear module 81, a first connecting seat 82 that can move laterally due to the first X-axis linear module 81, and a loading carrier 83 installed on the first connecting seat 82 for placing the silicone pad thereon. In this way, the silicone pad positioning and conveying mechanism 8 drives the first connecting seat 82 and the loading carrier 83 to move laterally through the first X-axis linear module 81, thereby realizing the automatic conveyance of the silicone pad from the previous external station to the silicone pad loading station 1, thereby improving production efficiency. The setting of the loading carrier 83 installed on the first connecting seat 82 can ensure that the silicone pad is accurately placed on the silicone pad loading station 1 by accurately controlling the movement of the first X-axis linear module 81, thereby reducing the adjustment time in the subsequent assembly process and improving the consistency and quality of the product.

[0039] As Figures 6 to 8 shown, in specific implementation, the device body 100 is further provided with a cam mechanism for loosening the silica gel pad in the loading carrier 83 when the manipulator 3 needs to clamp; the first connecting seat 82 is provided with an end face positioning seat 84 capable of moving forward and backward at the rear side of the loading carrier 83, a first side positioning seat 85 capable of moving left and right below the loading carrier 83, and a second side positioning seat 86 capable of moving left and right and cooperating with the first side positioning seat 85 to jointly clamp or loosen the silica gel pad in the loading carrier 83; the cam mechanism includes: a first lifting assembly 881 arranged below the first connecting seat 82, a first roller 882 arranged on the top of the first lifting assembly 881, a first push block 883 cooperating with the first roller 882 for converting the force of the up and down movement of the first lifting assembly 881 into the force for driving the end face positioning seat 84 to move forward and backward, a second roller 884 connected to one side of the end face positioning seat 84 and rolling along the left side face of the first side positioning seat 85, and a third roller 885 opposite to the second roller 884 left and right and rolling along the right side face of the second side positioning seat 86; the left side face of the first side positioning seat 85 and the right side face of the second side positioning seat 86 are both inclined planes extending inwards from the rear to the front.

[0040] As described above, through the cooperation setting of the cam mechanism, its first roller, second roller, third roller, and the inclined planes of the first side positioning seat and the second side positioning seat in this case, the secondary positioning device in this case can achieve the positioning of the silica gel pad on the end face, the first side, and the second side only by using a set of first lifting assemblies, greatly reducing the number of required cylinders and the space occupied on the XY plane. This not only makes the structure of the entire device more compact, but also avoids the interference problem with surrounding equipment, improving the overall layout flexibility of the production line. Moreover, such a design also reduces the number of cylinders and other electrical components used, directly reducing the material cost and manufacturing cost.

[0041] As Figures 6 to 8As shown, as a preferred embodiment, the feeding carrier 83 is provided with one or more material grooves 831 for placing silica gel pads therein. Each material groove 831 is provided with a first opening groove 832 at the end face position of the silica gel pad, a first side through port 833 on the first side face of the end face of the silica gel pad, and a second side through port 834 on the second side face of the end face of the silica gel pad; on the first side face positioning seat 85, there are first clamping blocks 851 extending backward and upward with the same number as the material grooves 831, and the second side face positioning seat 86 is provided with one or more second clamping blocks 861 extending forward and upward and opposite to the first clamping blocks 851 left and right; the first clamping blocks 851 penetrate upward through the first side through port 833, and the second clamping blocks 861 penetrate upward through the second side through port 834. During specific implementation, the first clamping block and the second clamping block located on the left and right sides of the same material groove and opposite to each other form a clamping jaw, and the first clamping block and the second clamping block can be made to approach or move away from each other through the movement of the cam mechanism, so that the clamping jaw can clamp and release the silica gel pad. During specific implementation, the first connecting seat 82 is respectively provided with a first limit fixing block 821, a second limit fixing block 822, and a third limit fixing block 823 at the end positions of the movement strokes of the end face positioning seat 84, the first side face positioning seat 85, and the second side face positioning seat 86, and a second spring 891 is connected between the first limit fixing block 821 and the rear end of the end face positioning seat 84, a third spring 892 is connected between the second limit fixing block 822 and the right end of the first side face positioning seat 85, and a fourth spring 893 is connected between the third limit fixing block 823 and the left end of the second side face positioning seat 86; thus, through the arrangement of the second spring 891, the third spring 892, and the fourth spring 893, when not lifted by the first lifting assembly, it can adaptively rebound and clamp, improving the automation degree and flexibility of the equipment.

[0042] As described above, the feeding trough is arranged so that the silica gel pad can be automatically aligned to a predetermined position during placement without excessive adjustment by humans. This is beneficial to improving the accuracy and efficiency of the subsequent automated assembly process. The arrangement of the first opening trough enables the protruding part on the end face positioning seat to extend into and withdraw from the feeding trough to press and position the end face of the silica gel pad, so that the end face positioning seat can accurately fix the end face of the silica gel pad. Multiple feeding troughs can be arranged on one silica gel pad carrier, so that multiple silica gel pads can be processed simultaneously, improving the utilization rate and productivity of the equipment. The common arrangement of the first side through port and the second side through port enables the first clamping block and the second clamping block to accurately penetrate through the left and right sides of the silica gel pad, so that the two side faces of the silica gel pad of the secondary positioning device in this case can be accurately positioned and fixed in the carrier. The automated assembly robot can be more smooth and efficient during the material taking and assembly processes, thereby reducing the downtime for adjustment caused by inaccurate positions of the silica gel pads and improving the overall efficiency of the assembly process. In addition, the arrangement that the first clamping block extends backward and upward and the second clamping block extends forward and upward can make full use of the longitudinal space on the mounting seat, which is beneficial to a more compact arrangement.

[0043] As Figure 9 and Figure 10 As shown, during specific implementation, a plurality of transport carriers 21 are evenly distributed along the circumference of the turntable 2. Each transport carrier 21 includes a fixed base 211, a first positioning seat 212 protruding from the outer edge of the fixed base 211, and a second positioning seat 213 protruding from the inside of the fixed base 211 and capable of approaching or departing from the first positioning seat 212 through radial movement. The first positioning seat 212 is provided with a plurality of first semi-opening troughs 2120 on the side close to the second positioning seat 213, facing the second positioning seat 213 and having a shape matching the shape of the rear half of the connecting seat. The second positioning seat 213 is provided with a plurality of second semi-opening troughs 2130 on the side close to the first positioning seat 212, facing the first positioning seat 212 and having a shape matching the shape of the front half of the connecting seat. The first semi-opening troughs 2120 and the second semi-opening troughs 2130 form a limiting space for the connecting seat to swing into. A fixed vertical block 214 parallel and opposite to the first positioning seat 212 and the second positioning seat 213 protrudes from the innermost edge of the fixed base 211. A first spring 215 is connected between the fixed vertical block 214 and the second positioning seat 213.

[0044] As described above, the multiple transport carriers 21 designed on the turntable 2 are so that multiple connection seats 202 can be transported at one time. The first half-open groove 2120 and the second half-open groove 2130 respectively provided in the first positioning seat 212 and the second positioning seat 213 are precisely matched with the shapes of the front and rear halves of the connection seat, forming a stable limiting space, so that the connection seat can be accurately positioned during the swing-in process, thereby improving the accuracy and consistency of assembly. The second positioning seat 213 can be moved closer to or away from the first positioning seat 212 by radial movement, so as to be dynamically adjusted according to the connection seats of different sizes, so that the connection seats of different sizes can be effectively clamped and positioned, and products with different connection seats and silicone pads can be produced, with strong compatibility, and the adaptability and strain capacity of the production line are improved. The automatic reset function of the second positioning seat is realized by the setting of the first spring 215. When the connection seat is placed or taken out, the second positioning seat can automatically adjust its position to adapt to the new state without manual intervention.

[0045] like Figure 10 As shown, in a specific implementation, a plurality of second lifting assemblies 9 for opening the transport carrier 21 are provided below the turntable 2, and a fourth roller 91 is provided on the top of the second lifting assemblies 9, and the transport carrier 21 is provided with a second push block 92 along which the fourth roller 91 can roll and drive the second positioning seat 213 to move away from the first positioning seat 212 to open the transport carrier 21. In addition, the device of this case is also provided with a material picking station 300 for an external device to clamp the assembled product immediately after the first visual inspection mechanism 5 along the running direction of the turntable 2, and a connecting seat loading station 400 for placing the connecting seat clamped by an external device before the silicone pad loading station 1; the second lifting assemblies 9 include at least two, one of which is provided at the material picking station 300 and is located below the turntable 2, and the other is provided at the connecting seat loading station 400 and is located below the turntable 2.

[0046] As described above, by arranging a plurality of second lifting components 9 below the turntable 2 and using the fourth rollers 91 at their tops to interact with the second push blocks 92 on the transport vehicle 21, the automatic opening and closing of the transport vehicle are achieved, further improving the automation degree of the production line, reducing manual intervention, and lowering the operation difficulty and labor intensity. The material taking station 300 and the connecting seat feeding station 400 are respectively located at different positions in the running direction of the turntable 2, making the whole assembly process more orderly and efficient. The material taking station follows closely after the first vision inspection mechanism 5, ensuring that only the products that have passed the inspection and are qualified will be taken out; the connecting seat feeding station prepares the connecting seat in advance for the next assembly cycle, reducing the waiting time. In addition, by arranging at least two second lifting components 9, one for the material taking station 300 and the other for the connecting seat feeding station 400, the operations of taking out the product and putting in the connecting seat can be carried out simultaneously during the rotation of the turntable, so as to improve the production efficiency.
