Description

Technical Field

[0001] The utility model relates to the technical field of buffer assembly equipment, in particular to a detection and discharging mechanism for buffer assembly. Background Art

[0002] The main uses of the buffer are to buffer load impacts in machine equipment, avoid collision damage, eliminate noise, increase the cycle speed, improve product quality, etc.; among them, the buffer is composed of a buffer base, a pulley, a slider component, an oil cylinder, and a spring. In the assembly process of the buffer, the pulley is sequentially assembled on the positioning post of the buffer base, the slider component is assembled on the slide rail of the buffer base, the oil cylinder is assembled in the oil cylinder placement groove, and the spring is assembled in the spring placement groove (as Figures 4-5 shown), and then the assembly of the buffer can be completed.

[0003] After the existing buffer assembly equipment completes the assembly of the buffer, the assembled buffer is carried away from the assembly equipment by a clamping mechanism for subsequent material collection processing. However, during the process of collecting the assembled buffer, whether the assembled buffer is qualified or not, they will be collected together, thus affecting the quality of batch production of the buffer; moreover, in the follow-up, the unqualified buffers need to be separated additionally, increasing the workload and cost. Therefore, a detection and discharging mechanism for buffer assembly is provided to solve the above technical problems. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a detection and discharging mechanism for buffer assembly aiming at the deficiencies of the prior art, so as to solve the technical problem that whether the assembled buffer is qualified or not, they will be collected together, thus affecting the quality of batch production of the buffer.

[0005] To achieve the above purpose, the technical solution of the utility model is as follows:

[0006] A detection and discharging mechanism for buffer assembly includes a machine platform and a turntable horizontally and intermittently rotating on the machine platform. The turntable is equipped with several assembly position jigs arranged in an array around its rotation center point; it also includes a first support frame placed beside the turntable. On the first support frame, there is a movable frame that can move up and down and horizontally, and a clamping jaw cylinder with its execution end facing down is installed on the movable frame. On both execution ends of the clamping jaw cylinder, there are clamping blocks for clamping the length sides of the buffer placed on the assembly position jig. A conveying component for conveying and discharging the assembled buffer is installed on the machine platform, and the initial end of the conveying component is placed at the end of the horizontal movement track of the movable frame; a detection component for detecting whether each component on the buffer is assembled is installed on the movable frame, and a pushing component for pushing the unqualified assembled buffer away from the conveying component is installed at the initial end of the conveying component.

[0007] Advantages of the present utility model: After assembling the buffer, the control component controls the movable frame to move downward, and the detection component can detect whether the components on the buffer (i.e., the pulley, the slider component, the oil cylinder, and the spring) are assembled. When the detection is completed, the two clamping blocks are respectively placed on both sides of the length side of the buffer. Finally, the clamping jaw cylinder is controlled to clamp the buffer through the clamping blocks, and the control component controls the movable frame to move horizontally to transport the buffer to the initial end of the conveying component; the detection component uploads the information on whether the buffer is qualified. When an unqualified buffer is detected, the pushing component is controlled to operate to push the unqualified buffer away from the conveying component. On the contrary, when a qualified buffer is detected, the pushing component does not operate, and the buffer is transported out of the buffer assembly device through the conveying component, realizing the detection and discharging process of the buffer.

[0008] During the process of transporting the assembled buffer from the assembly jig to the conveying component, the detection component detects whether the components on the buffer are assembled, and then cooperates with the pushing component to separate the qualified and unqualified buffers, improving the quality and assembly efficiency of the buffer assembly process.

[0017] The following combines the drawings to describe in detail a detection and discharging mechanism for buffer assembly of the present utility model.

[0018] As Figures 1-3 shown, an embodiment of a detection and discharging mechanism for buffer assembly of the present utility model includes a machine 102 and a turntable 103 horizontally rotatably arranged on the machine 102. The turntable 103 rotates intermittently, and a plurality of assembly position jigs 105 arranged in an array around its rotation center point are installed on the turntable 103. The assembly position jig 105 is a working position for assembling the buffer. The turntable 103 drives the assembly position jig 105 to rotate intermittently, and cooperates with a feeding mechanism for feeding buffer components (i.e., buffer base 1001, pulley 1003, slider component 1005, spring 1009, etc.), and sequentially places the various components of the buffer on the same assembly position jig 105 according to the assembly process for assembly processing. After assembly, it is necessary to move it away from the assembly position jig 105, and it is also necessary to perform detection processing to detect whether the assembled buffer is qualified.

[0019] In order to enable the turntable 103 to rotate intermittently automatically on the machine table 102, the machine table 102 is equipped with an intermittent drive component 104 for driving the rotation of the turntable 103. By operating the intermittent drive component 104, the turntable 103 is driven to rotate intermittently. Specifically, when the turntable 103 rotates to drive one of the assembly position jigs 105 to align with the buffer base loading mechanism (not shown in the figure), the buffer base loading mechanism is operated to load the buffer base 1001 onto the assembly position jig 105. Subsequently, the turntable 103 is driven to rotate a specified angle again, and the assembly position jig 105 with the buffer base 1001 placed thereon is rotated to align with the pulley assembly mechanism (not shown in the figure). At the same time, the next assembly position jig 105 without the buffer base 1001 placed thereon is driven to align with the buffer base loading mechanism (not shown in the figure). Meanwhile, the pulley assembly mechanism (not shown in the figure) and the buffer base loading mechanism (not shown in the figure) are operated. The pulley assembly mechanism (not shown in the figure) assembles the pulley 1003 onto the positioning post 1002 of the buffer base 1001. After the pulley 1003 is assembled, the turntable 103 is driven to rotate a specified angle again to drive the buffer base 1001 with the pulley 1003 assembled thereon to align with the slider component assembly mechanism (not shown in the figure). The slider component assembly mechanism (not shown in the figure) is operated to load and assemble the slider component 1005 onto the slide rail 1004 of the buffer base 1001 (as Figure 4 shown); then the turntable 103 is driven to rotate a specified angle again to drive the buffer base 1001 with the pulley 1003 and the slider component 1005 installed thereon to align with the oil cylinder assembly mechanism (not shown in the figure). The oil cylinder assembly mechanism (not shown in the figure) is operated to perform an automatic feeding and assembly process on the oil cylinder 1007, thereby assembling the oil cylinder 1007 into the oil cylinder placement groove 1006 on the buffer base 1001. Then the turntable 103 is driven to rotate a specified angle again to drive the buffer base 1001 with the pulley 1003, the slider component 1005, and the oil cylinder 1007 installed thereon to align with the spring automatic assembly mechanism (not shown in the figure). By operating the spring automatic assembly mechanism, the spring 1009 can be assembled into the spring placement groove 1008 on the buffer base 1001, thus completing the assembly of the buffer. The above is the entire process of assembling one buffer. While one buffer placed on the assembly position jig 105 is being assembled, the buffer placed on the next assembly position jig 105 is also being assembled in sequence. The intermittent drive component 104 is a prior art. In practice, a servo motor assembly can be used, or a structure such as a defective gear driving a full gear to rotate intermittently that can drive the turntable 103 to rotate intermittently can be adopted, which will not be elaborated here.

[0020] When the spring automatic assembly mechanism (not shown in the figure) assembles the spring 1009, according to different models of buffers, it is necessary to assemble the corresponding model of spring 1009. The models of the spring 1009 are divided into "U" shapes (such asFigure 4 as shown) and "I" shape (such as Figure 5 shown); wherein, a second card slot 10091 is formed on the buffer base 1001, and a third card slot 10092 is formed on the slider member 1005. When assembling the "U" - shaped spring 1009 into the spring placement groove 1008, one end of the "U" - shaped spring 1009 is snapped into the second card slot 10091, the other end is snapped into the third card slot 10092, and the bent portion of the "U" - shaped spring 1009 is wound around the pulley 1003, thus completing the assembly of the "U" - shaped spring 1009. In addition, a fourth card slot 10093 is also formed on the buffer base 1001. When assembling the "I" - shaped spring 1009, one end of the "I" - shaped spring 1009 is snapped into the third card slot 10092, and the other end is snapped into the fourth card slot 10093, and the "I" - shaped spring 1009 will not be wound around the pulley 1003. By assembling springs 1009 of different shapes to assemble buffers of different models, after the assembly is completed, subsequent inspection processes and discharging processes are carried out.

[0021] Among them, this inspection and discharging mechanism further includes a first support frame 81 placed beside the turntable 103. There is a movable frame 82 on the first support frame 81 that can move up and down and horizontally, and a jaw cylinder 84 with its execution end arranged downward is installed on the movable frame 82. Clamping blocks 85 for clamping the length sides of the buffer placed on the assembly jig 105 are provided on both execution ends of the jaw cylinder 84. The movable frame 82 drives the jaw cylinder 84 and the clamping blocks 85 on both execution ends to move downward by a specified distance, so that the clamping blocks 85 are respectively placed on both sides of the length side of the buffer, and then the jaw cylinder 84 is operated to clamp the assembled buffer for subsequent handling. In addition, convex portions 851 extending towards each other are provided at the bottom ends of the two clamping blocks 85. After the buffer is clamped by the two clamping blocks 85, the convex portions 851 will support the bottom of the buffer, making the handling process more stable and preventing the buffer from falling.

[0022] In addition, a control component 83 for controlling the up - and - down movement and horizontal movement of the movable frame 82 is installed on the first support frame 81. By operating the control component 83, the movable frame 82 can be automatically moved up and down and horizontally on the first support frame 81. A pressure rod 821 for resisting the end of the buffer during handling is provided on the movable frame 82. When the convex portions 851 are respectively placed on both sides of the length side of the buffer, the pressure rod 821 just presses against the end of the buffer. During the handling of the buffer, the cooperation between the pressure rod 821 resisting the end of the buffer and the convex portions 851 supporting the bottom of the buffer further improves the stability of handling.

[0023] Further, a conveying component 815 for conveying and discharging the assembled buffer is also installed on the machine platform 102. The initial end of the conveying component 815 is placed at the end of the lateral movement track of the movable frame 82. The operation control component 83 first controls the clamping jaw cylinder 84 to move downward to clamp the assembled buffer, then controls the clamping jaw cylinder 84 to move upward and laterally to carry the buffer onto the conveying component 815, and then cooperates with the intermittent rotation of the turntable 103 to carry the assembled buffers onto the conveying component 815 one by one, and operates the conveying component 815 to convey the buffer out of the buffer assembly device.

[0024] In order to detect the assembled buffer, a detection component for detecting whether each component on the buffer is assembled is provided on the movable frame 82, and a pushing component 816 for pushing the unqualified buffer away from the conveying component 815 is installed at the initial end of the conveying component 815, and a receiving frame 817 for collecting the unqualified buffer is provided beside the conveying component 815.

[0025] During the process of the control component 83 controlling the movable frame 82 to move downward, the detection component can detect whether each component (i.e., the pulley 1003, the slider component 1005, the oil cylinder 1007, the spring 1009) on the buffer is assembled. At the same time as the detection is completed, the two clamping blocks 85 are respectively placed on both sides of the length side of the buffer. Finally, the control component 83 controls the clamping jaw cylinder 84 to clamp the buffer through the clamping blocks 85, and controls the movable frame 82 to move laterally to carry the buffer to the initial end of the conveying component 815. The detection component feeds back the information of whether the buffer is qualified to the controller (not shown in the figure). When it is detected that the buffer is unqualified, the controller controls the pushing component 816 to operate to push the unqualified buffer into the receiving frame 817 for collection. On the contrary, when it is detected that the buffer is qualified, the pushing component 816 does not operate, and the buffer is conveyed out of the buffer assembly device through the conveying component 815, realizing the detection and discharging process of the buffer.

[0026] The control component 83 includes a laterally arranged guide rail 831. A sliding seat 832 is slidably provided on the guide rail 831. Under the action of the guide rail 831, the sliding seat 832 slides laterally on the first support frame 81. In order to drive the sliding seat 832 to slide automatically, a laterally arranged linear drive module 833 is installed on the first support frame 81, and the movable end of the linear drive module 833 is fixedly arranged with the sliding seat 832. By operating the linear drive module 833, the sliding seat 832 can be controlled to slide laterally on the first support frame 81. The sliding seat 832 is provided with a first cylinder 834 with a telescopic rod arranged downward, and the movable frame 82 is fixedly arranged with the telescopic rod of the first cylinder 834. By operating the first cylinder 834, the movable frame 82 can be controlled to move up and down, and in cooperation with the lateral sliding of the sliding seat 832, the movable frame 82 can also move laterally.

[0027] Preferably, the conveying component 815 includes a second support frame 8151 and a belt conveying module 8152 installed on the second support frame 8151. The belt conveying module 8152 is used to convey the assembled and qualified buffers out of the buffer assembly equipment. Among them, a horizontally arranged driving motor 8153 is also installed on the second support frame 8151, and a driving roller 8154 is provided at the end of the output shaft of the driving motor 8153. The belt on the belt conveying module 8152 is wound around the driving roller 8154. By operating the driving motor 8153, the driving roller 8154 is controlled to rotate, so as to drive the belt on the belt conveying module 8152 to move, realizing the conveying process of the buffer. Additionally, a material guiding frame 8155 is installed at the end of the belt conveying module 8152. Through the material guiding frame 8155, the assembled and qualified buffers are guided to a specified position for collection.

[0028] The pushing component 816 includes a mounting plate 8161 arranged beside the second support frame 8151 and a second cylinder 8612 installed on the mounting plate 8161. The second cylinder 8612 is horizontally arranged and the telescopic rod is aligned with the initial end of the belt conveying module 8152. A push plate 8163 for pushing the unqualified buffers placed at the initial end of the belt conveying module 8152 into the material receiving frame 817 is provided at the end of the telescopic rod of the second cylinder 8612. After the assembled buffers are transported to the initial end of the belt conveying module 8152, if unqualified buffers are detected, the second cylinder 8612 is operated to control the movement of the push plate 8163 to push the unqualified buffers into the material receiving frame 817.

[0029] Such as Figure 3As shown in the figure, the detection component includes a first guide block 86 and a second guide block 810 fixedly arranged on the movable frame 82. The first guide block 86 is provided with a pulley probe rod 87 that moves up and down and is used to contact the pulley 1003 assembled on the positioning column 1002, and a first spring probe rod 88 and a second spring probe rod 89 that are used to contact the spring 1009 assembled in the spring placement groove 1008. The bottom end of the pulley probe rod 87 is provided with a groove 871 for the positioning column 1002 to be inserted into. When the control sliding seat 832 moves downward, it drives the pulley probe rod 87, the first spring probe rod 88, and the second spring probe rod 89 to move downward together. When the detected spring 1009 is in a "U" shape, the bottom ends of the first spring probe rod 88 and the second spring probe rod 89 contact the spring 1009 at the same time, and the bottom end of the pulley probe rod 87 contacts the pulley 1003. The sliding seat 832 continues to move downward, causing the pulley probe rod 87, the first spring probe rod 88, and the second spring probe rod 89 to move upward on the first guide block 86 by a specified distance at the same time. If the distance exceeds or fails to reach this distance, it means the detection is unqualified; when the detected spring 1009 is in an "I" shape, the second spring probe rod 89 does not contact the spring 1009, and only the pulley probe rod 87 and the first spring move upward by a specified amount on the first guide block 86.

[0030] Furthermore, the second guide block 810 is provided with an oil cylinder probe rod 811 that moves up and down and is used to contact the oil cylinder 1007 assembled in the oil cylinder placement groove 1006, and a slider probe rod 812 that is used to contact the slider component 1005 assembled on the slide rail 1004. In the same detection method as above, when the control sliding seat 832 moves downward, it drives the oil cylinder probe rod 811 and the slider probe rod 812 to move downward together. The bottom end of the oil cylinder probe rod 811 contacts the assembled oil cylinder 1007, and the bottom end of the slider probe rod 812 contacts the slider component 1005. After contact, the sliding seat 832 continues to move downward, and the oil cylinder probe rod 811 and the slider probe rod 812 move upward on the second guide block 810 by a specified distance. If the distance exceeds or fails to reach this distance, it means the detection is unqualified.

[0031] A number of first induction components are provided on the first guide block 86 for respectively sensing the upward movement of the pulley probe rod 87, the first spring probe rod 88, and the second spring probe rod 89 by a specified distance. A number of second induction components are provided on the second guide block 810 for respectively sensing the upward movement of the oil cylinder probe rod 811 and the slider probe rod 812 by a specified distance. The structures of the first induction components and the second induction components are the same. Among them, the first induction component includes a mounting block 813 and an inductor 814 installed on the mounting block 813. The inductor 814 is used to sense the position of the probe rod corresponding to it. When the corresponding probe rod moves upward by a specified distance, it means that the component corresponding to the probe rod is successfully assembled on the buffer base 1001. On the contrary, if the upward movement distance of the probe rod is not within the set value, it means that the component corresponding to the probe rod is not successfully installed, which is convenient for subsequent sorting of qualified and unqualified buffers.

[0032] In summary, it can be seen that the present utility model has the excellent characteristics described above, enabling it to enhance the efficiency never achieved in the prior art during use and thus having practicality, becoming a product with extremely high practical value.

[0033] The above content is only the preferred embodiment of the present utility model. For those of ordinary skill in the art, based on the idea of the present utility model, there will be changes in the specific implementation manner and application scope. The content of this specification should not be construed as a limitation to the present utility model.
