Description

Technical Field

[0001] The present invention relates to the technical field of mechanical automation, and more particularly, to a sorting mechanism for lead terminals. Background Art

[0002] The feeding and picking efficiency of the lead terminals of a relay directly affects the production efficiency of subsequent processes. Currently, there are obvious deficiencies in the matching of the feeding rhythm and picking rhythm of existing lead terminal feeding systems. Existing feeders usually rely on manual operation or simple automation systems, and these systems are difficult to meet the needs of high-efficiency production in terms of feeding accuracy and speed. Especially during continuous production, the rhythm of feeding and picking is inconsistent, resulting in low production efficiency. In addition, existing feeding systems lack the ability to accurately position the lead terminals, which easily leads to installation position deviations of the lead terminals in subsequent processes and affects product quality. Therefore, how to achieve efficient matching of the feeding and picking rhythms of lead terminals and improve the production efficiency of automated equipment has become a key problem to be solved by the present invention.

Detailed implementation manners

[0016] Combined with Figure 1 and Figure 2 shown, this embodiment provides a material separation mechanism for lead-out terminals, aiming to solve the problem that it is difficult to match the feeding and picking rhythms of lead-out terminals in the prior art, and improve the production efficiency of automatic equipment through efficient material separation and accurate positioning. The following combines the attached Figure 1 、attached Figure 2 , and details the specific implementation manners of the present invention.

[0017] See attached Figure 1, this embodiment provides a feeding mechanism for lead terminals, which mainly includes a feeding bottom plate 2, a blocking cylinder plate 1, a feeding cylinder A 3, a feeding cylinder B 4, a positioning cylinder C 10 and a cylinder D 14. The feeding bottom plate 2 serves as the basic platform for the entire feeding mechanism and is used to install and fix other components. The blocking cylinder plate 1 is arranged above the feeding bottom plate 2 and is used to install the cylinder D 14. A blocking cylinder D 14 is arranged on the blocking cylinder plate, and a material blocking block 13 is installed at its front end, which is used to block the redundant lead terminals 12. Specifically, it is adapted to extend the material blocking block from one side of the feeder to timely block the redundant lead terminals 12 from entering the feeding area. The feeding cylinder A 3 and the feeding cylinder B 4 are respectively arranged on the feeding bottom plate 2 and are respectively equipped with a gripper A 5 and a gripper B 7, which are used to fix the lead terminals 12; the gripper A 5 and the gripper A 7 are arranged side by side front and back and are respectively used to clamp one lead terminal 12, which makes the overall structure more compact and can save installation space. The positioning cylinder C 10 is arranged on the feeding bottom plate 2, and a positioning block 11 is installed at its front end, which is used to ensure the position accuracy of the lead terminals 12. Specifically, the positioning cylinder C 12 is arranged at the rear end of the gripper A 7, and the positioning block 11 is arranged at the rear end of the gripper A 7 to position the lead terminals 12 from the rear end.

[0018] See the appendix Figure 2 , a feeding finger A 6 is arranged on the gripper A 5, and a feeding finger B 8 is arranged on the gripper B 7. The feeding finger A 6 and the feeding finger B 8 are respectively used to clamp and fix the lead terminals 12. The feeding cylinder A 3 and the feeding cylinder B 4 are also provided with a position detection seat 9, which is used to detect whether the lead terminals 12 are in the correct position. The position detection seat 9 can adopt detection elements such as photoelectric sensors and proximity switches to ensure the correct position of the lead terminals 12 at the gripper A 5 and the gripper B 7. The positioning cylinder C 10 positions the lead terminals 12 accurately by pushing out the positioning block 11. The design of the positioning block 11 should consider the shape and size of the lead terminals 12 to ensure the position accuracy of the lead terminals 12 during the feeding process.

[0019] A material blocking block 13 is arranged on the cylinder D 14, which is used to block the redundant lead terminals 12. The design of the material blocking block 13 should match the size of the lead terminals 12 to ensure that the redundant lead terminals 12 can be effectively blocked during the feeding process and prevent them from entering the feeding area. The action of the cylinder D 14 should be coordinated with the actions of the feeding cylinder A 3 and the feeding cylinder B 4 to ensure the smooth progress of the feeding process.

[0020] The working process of the present invention includes the following steps:

[0021] S1. The feeder transports the lead terminals 12 to the air gripper A5 and the air gripper B7. The feeder can be an automated feeding device such as a vibrating bowl feeder or a linear feeder, and its function is to orderly transport the lead terminals 12 to the entrance of the material distribution mechanism. The outlet position of the feeder should correspond to the positions of the air gripper A5 and the air gripper B7 to ensure that the lead terminals 12 can accurately enter the fixed positions. Before the lead terminals 12 enter the positions of the air gripper A5 and the air gripper B7, the cylinder D14 should be in the retracted state to facilitate the smooth passage of the lead terminals 12.

[0022] S2. The air gripper A5 and the air gripper B7 fix the lead terminals 12 through the material distribution clamping fingers A6 and the material distribution clamping fingers B8, and at the same time, the in-place detection seat 9 confirms whether the lead terminals 12 are correctly in place. When the lead terminals 12 reach the air gripper A5 and the air gripper B7, the air gripper A5 and the air gripper B7 respectively clamp and fix them through the material distribution clamping fingers A6 and the material distribution clamping fingers B8. The designs of the material distribution clamping fingers A6 and the material distribution clamping fingers B8 should consider the shape and size of the lead terminals 12 to ensure that the lead terminals 12 will not be damaged during the clamping process. The in-place detection seat 9 detects whether the lead terminals 12 are correctly in place through a photoelectric sensor or a proximity switch. If it detects that the lead terminals 12 are not in place, the system will issue an alarm signal and stop the subsequent material distribution actions to avoid production accidents caused by inaccurate positions of the lead terminals 12.

[0023] S3. The positioning cylinder C10 pushes out the positioning block 11 to accurately position the lead terminals 12. When the lead terminals 12 are fixed by the air gripper A5 and the air gripper B7, the positioning cylinder C10 acts to push out the positioning block 11 to accurately position the lead terminals 12. The pushing action of the positioning block 11 should be slow and steady to avoid impacting or deforming the lead terminals 12. The position of the positioning block 11 should correspond to the positions of the air gripper A5 and the air gripper B7 to ensure that the lead terminals 12 can remain stable during the material distribution process.

[0024] S4. The cylinder D14 pushes out the stop block 13 to block the excess lead terminals 12. When the lead terminals 12 are fixed and positioned by the air gripper A5 and the air gripper B7, the cylinder D14 acts to push out the stop block 13 to block the excess lead terminals 12 transported by the subsequent feeder. The design of the stop block 13 matches the size of the lead terminals 12 to ensure that it can effectively block the excess lead terminals 12 and prevent the excess lead terminals 12 from entering the material distribution area. The pushing action of the stop block 13 is fast and accurate, which can avoid the excess lead terminals 12 from entering the material distribution area. The action of the cylinder D14 is coordinated with the action of the positioning cylinder C10 to ensure that the stop block 13 can be pushed out in time during the material distribution process to avoid interfering with the material distribution process.

[0025] In S5, the material separating cylinder A3 and the material separating cylinder B4 act to complete the material separating process. After the lead-out terminal 12 is fixed and positioned by the air gripper A5 and the air gripper B7, the material separating cylinder A3 and the material separating cylinder B4 act respectively to separate the lead-out terminal 12 from the feeder and move it to the specified position. The actions of the material separating cylinder A3 and the material separating cylinder B4 are stable and accurate, which can ensure the position accuracy of the lead-out terminal 12 during the material separating process. The strokes of the material separating cylinder A3 and the material separating cylinder B4 can be adjusted according to actual requirements to adjust the distance between the two lead-out terminals 12 after material separation, so as to meet different material taking requirements. The actions of the material separating cylinder A3 and the material separating cylinder B4 are coordinated with the action of the cylinder D14 to ensure that the baffle 13 can withdraw in time during the material separating process to avoid interfering with the material separating process.

[0026] Through the above steps, this embodiment can achieve efficient material separation and precise positioning of the lead-out terminal 12, ensure the position accuracy of the lead-out terminal 12 during the material separating process, and improve the production efficiency of the automatic equipment. The specific implementation manner of the present invention is not only applicable to the production of high-voltage DC relays, but also can be widely applied to other automatic production lines that require material separation and positioning of lead-out terminals.

[0027] Particularly, the present invention can adjust the distance between the two lead-out terminals 12 after material separation by adjusting the strokes of the material separating cylinder A3 and the material separating cylinder B4, so as to meet different material taking requirements. For example, during the production process, if it is necessary to separate the lead-out terminal 12 to different workstations, the strokes of the material separating cylinder A3 and the material separating cylinder B4 can be adjusted to make the distance between the lead-out terminals 12 after material separation match the distance between the workstations, ensuring the smooth progress of the material taking process. In addition, this embodiment can also realize simultaneous material separation and positioning of multiple lead-out terminals 12 by adding more material separating cylinders and air grippers, further improving the production efficiency.

[0028] In specific applications, the material separating mechanism of the present invention can be integrated with the control system of the automatic production line to achieve automatic control through a PLC or other control devices. The control system can adjust the actions of the material separating cylinder A3, the material separating cylinder B4, the positioning cylinder C10 and the cylinder D14 in real time according to the detection results of the in-place detection seat 9 to ensure the high efficiency and accuracy of the material separation and positioning process of the lead-out terminal 12. For example, when the in-place detection seat 9 detects that the lead-out terminal 12 is not in place, the control system can send out an alarm signal and stop the subsequent material separating actions until the lead-out terminal 12 is in the correct position. After the lead-out terminal 12 is in the correct position, the control system can start the positioning cylinder C10, the cylinder D14, the material separating cylinder A3 and the material separating cylinder B4 in sequence to complete the material separating process.

[0029] To ensure the stability and reliability of the material separation mechanism, the materials of the material separation bottom plate 2 and the blocking cylinder plate 1 can be selected as high-strength and wear-resistant materials, such as aluminum alloy or stainless steel, to ensure that they will not deform or be damaged during long-term use. The material separation cylinder A3, the material separation cylinder B4, the positioning cylinder C10, and the cylinder D14 are selected as cylinders with stable performance and fast response speed, such as double-acting cylinders, to ensure the accurate operation of the material separation process. The gripper A5 and the gripper B7 are selected as grippers with high clamping force and reliability, such as magnetic grippers or mechanical grippers, to ensure the fixing effect of the lead terminal 12 during the clamping process. The in-place detection seat 9 is selected as a detection element with high sensitivity and a wide detection range, such as a photoelectric sensor or a proximity switch, to ensure that it can accurately detect the in-place situation of the lead terminal 12.

[0030] In actual operation, the material separation mechanism of the present invention can achieve the material separation and positioning of lead terminals 12 of different models and sizes by adjusting the action parameters of each cylinder. For example, for the lead terminal 12 with a smaller size, the strokes of the material separation cylinder A3 and the material separation cylinder B4 can be appropriately reduced to ensure that the spacing between the lead terminals 12 after material separation is appropriate; for the lead terminal 12 with a larger size, the strokes of the material separation cylinder A3 and the material separation cylinder B4 can be appropriately increased to ensure that the spacing between the lead terminals 12 after material separation meets the material taking requirements. In addition, by adjusting the pushing speed and force of the cylinder D14, it can be ensured that the baffle block 13 can effectively block the excess lead terminals 12 and prevent them from entering the material separation area.

[0031] The material separation mechanism of this embodiment can also be used in combination with other automated equipment to achieve the automated production and assembly of lead terminals 12. For example, on the production line of high-voltage DC relays, the material separation mechanism can be integrated with equipment such as welding robots and vision inspection systems to achieve the automatic material separation, positioning, welding, and inspection of lead terminals 12. The welding robot can identify the position of the lead terminals 12 after material separation through the vision inspection system and perform precise welding; the vision inspection system can detect the welding quality of the lead terminals 12 after welding to ensure that the product quality meets the requirements. Through the above integration, the production efficiency and product quality of high-voltage DC relays can be significantly improved.

[0032] In a preferred embodiment, a plurality of in-place detection seats 9 can be provided on the material distribution bottom plate 2 to ensure that the in-place condition of the lead terminals 12 can be comprehensively detected during the material distribution process. Additionally, buffer devices can be provided on the air gripper A5 and the air gripper B7 to reduce the impact and vibration of the lead terminals 12 during the material distribution process and improve the material distribution accuracy. Further, an anti-slip structure can be provided on the stop block 13 to ensure that the lead terminals 12 can be firmly fixed when blocking the lead terminals 12, preventing them from sliding or falling. Preferably, by adding a stroke adjustment device for the cylinder, the stroke adjustment of the material distribution cylinder A3 and the material distribution cylinder B4 can be made more convenient and accurate to meet different production requirements.

[0033] In summary, this embodiment provides a material distribution mechanism for lead terminals. By means of the material distribution cylinder A3, the material distribution cylinder B4, and the positioning cylinder C10 provided on the material distribution bottom plate 2, in combination with the air gripper A5 and the air gripper B7, the lead terminals 12 are fixed and distributed. At the same time, the positioning block 11 is used to precisely position the lead terminals 12 to ensure the position accuracy of the lead terminals 12. By means of the cylinder D14 and its stop block 13 provided on the stop cylinder plate 1, the excess lead terminals 12 are effectively blocked from entering the material distribution area, avoiding interference with the material distribution process. Through the above design, the present invention achieves an accurate match between the feeding rhythm and the picking rhythm of the lead terminals 12, significantly improving the production efficiency of the automated equipment.
