Description

Technical Field

[0001] This utility model relates to the field of terminal processing technology, specifically to an automatic feeding device for metal terminal production. Background Technology

[0002] A terminal is a component that connects a circuit structure to an external conductor. In electrical engineering, a terminal often refers to a wiring terminal, also called a wiring terminal. Types include single-hole, double-hole, socket, and hook. Terminals are usually used to connect to rod-shaped plugs. Traditional terminals (copper lugs) are usually fixed socket structures. The metal parts that connect to the terminal are usually made of pressed metal tubes. However, for some metal parts terminals that require a certain thickness of tube material, stamping equipment is needed to stamp both ends of the copper column into metal tubes to ensure the thickness of the tube wall, and then press the metal tube into a terminal (copper lug).

[0003] In the existing stamping equipment, the cut copper column needs to be manually aligned and fed into the feeding mechanism during the stamping process. The feeding mechanism then sends the copper column into the mold for stamping to reduce the risk of personnel injury. However, in large-scale production, the method of manually aligning the copper column and feeding it into the feeding mechanism is inefficient and seriously affects production efficiency. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide an automatic feeding device for the production of metal terminals, so as to solve the technical problems in the background art mentioned above.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic feeding device for metal terminal production, comprising a feeding mechanism and a mounting frame. The mounting frame houses a holding frame and a first hydraulic cylinder. A sorting plate is connected inside the holding frame, and the bottom of the sorting plate is connected to the output end of the first hydraulic cylinder. A sorting groove is provided inside the holding frame. A guide box is connected to one side of the holding frame, and a second hydraulic cylinder is connected to the other side of the holding frame via the mounting plate. A push plate is connected to the output end of the second hydraulic cylinder. A limit plate is connected to one side of the push plate, and a notch is provided inside the limit plate. A pressure sensor is installed outside the second hydraulic cylinder, and a control panel is installed on one side of the mounting frame.

[0006] Furthermore, the feeding mechanism includes a third hydraulic cylinder and a fixed frame. The output end of the third hydraulic cylinder is connected to a limit frame. One end of the limit frame is connected to a clamp by bolts, and the top of the fixed frame is connected to a feed pipe.

[0007] By adopting the above technical solution, the copper material to be stamped falls into the top of the limiting frame through the feeding pipe. Driven by the output end of the third hydraulic cylinder, the limiting frame moves the clamp backward, so that the copper material falls into the clamp. Then, the third hydraulic cylinder pushes the limiting frame forward, so that the clamp moves to the corresponding position of the stamping equipment mold. At this time, the raw material falls into the punch hole of the mold and waits for stamping. At the same time, when the clamp moves forward, another copper material falls on the top of the limiting frame and waits to move forward. The above method realizes unmanned operation, thereby reducing the possibility of personnel injury.

[0008] Furthermore, the first hydraulic cylinder, the second hydraulic cylinder, the third hydraulic cylinder, and the pressure sensor are all electrically connected to the control panel, and the control panel has a built-in timing control program.

[0009] By adopting the above technical solution, the control panel is programmed to control the starting and extension distances of the first, second, and third hydraulic cylinders, as well as monitor the pressure values ​​of the pressure sensors, thereby achieving automatic feeding without the need for manual feeding of raw materials into the stamping equipment mold.

[0010] The control panel has a preset cycle program: the first hydraulic cylinder rises (5s) → pauses (2s) → falls (3s) → the second hydraulic cylinder moves forward (4s) → detects pressure (1s) → moves backward (2s) → the third hydraulic cylinder moves back and forth (8s). Each action is triggered by the photoelectric sensor and the pressure sensor to ensure the cycle is synchronized.

[0011] Furthermore, the bottom of the holding frame is inclined, and the inclination angle of the bottom of the holding frame is 30°-45°.

[0012] By adopting the above technical solution, when the top of the sorting plate is flush with the bottom of the holding frame, the copper material quickly rolls into the angle between the sorting plate and the inner wall of the holding frame, and is transferred to the sorting trough under the drive of the output end of the first hydraulic cylinder. By tilting the plate, the copper material can roll by itself without the need for manual straightening.

[0013] Furthermore, the top of the sorting plate is inclined, and the inclination angle of the top of the sorting plate matches the bottom of the holding frame.

[0014] By adopting the above technical solution and setting it at an angle, the copper material can roll into the included angle based on its own shape, thus straightening itself without human intervention.

[0015] Furthermore, the limiting plate penetrates through the guide box, and the limiting plate is slidably connected to the guide box.

[0016] By adopting the above technical solution, under the drive of the output end of the second hydraulic cylinder, the push plate pushes the copper material into the inside of the guiding box. The copper material is limited by the limiting plate to prevent it from slipping directly until the limiting box is filled (three). At this time, the notch is flush with the inner cavity of the limiting box to release the limit (the width of the notch is 1.5 times the diameter of the copper material), so that the copper material enters the feed pipe in batches in turn, avoiding blockage of the feed pipe caused by too much entering at one time.

[0017] Furthermore, the inside of the guiding box is coated with a Teflon coating.

[0018] By adopting the above technical solution, the Teflon has a low coefficient of friction and is wear-resistant. The friction resistance inside the guiding box is reduced by the Teflon coating, enabling the copper material to slide into the feed pipe more smoothly and reducing the probability of the copper material getting stuck in the guiding box.

[0019] Furthermore, the feed pipe penetrates through the fixing frame, and the top of the feed pipe is funnel-shaped.

[0020] By adopting the above technical solution, under the action of the self-gravity of the copper material, guided by the feed pipe, the copper material vertically falls onto the top of the limiting frame for convenient transfer. The funnel shape is conducive to receiving and guiding the copper column, preventing the copper column from falling outside the feed pipe and affecting the practicality of the device.

[0021] Furthermore, the longitudinal section of the push plate is in a "Ji" shape, and the push plate is slidably connected to the holding frame.

[0022] By adopting the above technical solution, through the "Ji" shape setting, the push plate can slide outside the holding frame and will not interfere with other components. Moreover, it can be guided and limited by the outer wall of the holding frame to prevent the push plate from shifting and affecting the practicality.

[0023] Furthermore, an observation port is provided on one side of the guiding box.

[0024] By adopting the above technical solution, the staff can observe the condition of the copper material inside the guiding box through the observation port. At the same time, when a copper material is stuck with incorrect position, a tool can be inserted into the guiding box through the observation port to straighten the stuck copper material, and the operation method is simple and fast.

[0025] In summary, the present utility model mainly has the following beneficial effects:

[0026] 1. The present utility model realizes the automatic alignment of copper materials through the cooperation of the inclined holding frame and the sorting plate, uses the limiting plate with a notch and the guiding box to achieve quantitative and anti-blocking feeding, and combines the linkage control of three hydraulic cylinders, which can replace manual labor to complete the whole process of copper material sorting, conveying and feeding, significantly improving the production efficiency and automation level of terminals;

[0027] 2. This utility model reduces the frictional resistance inside the guide box by using a Teflon coating, allowing the copper material to slide more smoothly into the feed pipe and reducing the probability of the copper material getting stuck in the guide box. At the same time, when copper material gets stuck, a tool can be used to reach into the guide box through the observation port to straighten the stuck copper material. The operation is simple and quick. Attached Figure Description

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0037] The embodiments of this utility model will be described below based on its overall structure.

[0038] Example 1: Automatic feeding device for metal terminal production, such as Figures 1-6As shown, the device includes a feeding mechanism 2 and a mounting frame 1. The mounting frame 1 houses a holding frame 3 and a first hydraulic cylinder 4. A sorting plate 5 is connected inside the holding frame 3, and the bottom of the sorting plate 5 is connected to the output end of the first hydraulic cylinder 4. A sorting groove 9 is provided inside the holding frame 3. A guide box 12 is connected to one side of the holding frame 3, and a second hydraulic cylinder 6 is connected to the other side of the holding frame 3 via the mounting plate. A push plate 8 is connected to the output end of the second hydraulic cylinder 6. A limit plate 10 is connected to one side of the push plate 8, and a notch 11 is provided inside the limit plate 10. A pressure sensor 7 is installed outside the second hydraulic cylinder 6. A control panel 13 is installed on one side of the mounting frame 1. The feeding mechanism 2 includes a third hydraulic cylinder 201 and a fixing frame 202. The output end of the third hydraulic cylinder 201... A limiting frame 204 is connected, with a clamp 205 bolted to one end. A feed pipe 203 is connected to the top of the fixed frame 202. The copper material to be stamped falls into the top of the limiting frame 204 through the feed pipe 203. Driven by the output of the third hydraulic cylinder 201, the limiting frame 204 moves the clamp 205 backward, causing the copper material to fall into the clamp 205. Then, the third hydraulic cylinder 201 pushes the limiting frame 204 forward, causing the clamp 205 to move to the corresponding position of the stamping equipment mold. At this time, the raw material falls into the punch hole of the mold and waits for stamping. At the same time, when the clamp 205 moves forward, another copper material falls on the top of the limiting frame 204 and waits to move forward. The above method realizes unmanned operation, thereby reducing the possibility of personnel injury.

[0039] See Figures 1-5 In the above embodiment, the first hydraulic cylinder 4, the second hydraulic cylinder 6, the third hydraulic cylinder 201, and the pressure sensor 7 are all electrically connected to the control panel 13. The control panel 13 has a built-in timing control program. The program is set inside the control panel 13. By executing the program through the control panel 13, the starting and extension distances of the first hydraulic cylinder 4, the second hydraulic cylinder 6, and the third hydraulic cylinder 201 are controlled respectively, and the pressure value of the pressure sensor 7 is monitored, thereby realizing automatic feeding without the need for manual feeding of raw materials into the stamping equipment mold.

[0040] Control panel 13 preset cycle program: First hydraulic cylinder 4 rises (5s) → pauses (2s) → falls (3s) → Second hydraulic cylinder 6 advances (4s) → detects pressure (1s) → retreats (2s) → Third hydraulic cylinder 201 reciprocates (8s).

[0041] See Figures 1-5 In the above embodiment, the bottom of the holding frame 3 is inclined, and the inclination angle of the bottom of the holding frame 3 is 30°-45°. When the top of the sorting plate 5 is flush with the bottom of the holding frame 3, the copper material quickly rolls into the angle between the sorting plate 5 and the inner wall of the holding frame 3, and is transferred to the sorting tank 9 under the drive of the output end of the first hydraulic cylinder 4. By inclining, the copper material can roll by itself without the need for manual straightening.

[0042] See Figures 1-5 , in the above embodiment, the top of the sorting plate 5 is inclined, and the inclination angle of the top of the sorting plate 5 matches the bottom of the containing frame 3. Through the inclined setting, the copper materials can roll into the included angle depending on their own shapes, so as to be automatically aligned without manual intervention.

[0043] Refer to Figure 3 , Figure 4 , Figure 5 and Figure 6 , in the above embodiment, the limiting plate 10 penetrates through the guiding box 12, and the limiting plate 10 is slidably connected to the guiding box 12. Under the drive of the output end of the second hydraulic cylinder 6, the pushing plate 8 pushes the copper materials into the interior of the guiding box 12. The copper materials are limited by the limiting plate 10 to prevent them from sliding directly. Until the limiting box is filled (three), at this time, the notch 11 is flush with the inner cavity of the limiting box to release the limit (the width of the notch 11 is 1.5 times the diameter of the copper materials), so that the copper materials enter the feed pipe 203 in batches in sequence, avoiding blockage of the feed pipe 203 caused by too many entering at one time.

[0044] Refer to Figure 3 , in the above embodiment, the inner part of the guiding box 12 is coated with a Teflon coating. The Teflon has a low friction coefficient and is wear-resistant. By means of the Teflon coating, the frictional resistance inside the guiding box 12 is reduced, so that the copper materials can slide into the feed pipe 203 more smoothly, reducing the probability of the copper materials getting stuck in the guiding box 12.

[0045] Refer to Figure 1 , Figure 4 and Figure 5 , in the above embodiment, the feed pipe 203 penetrates through the fixing frame 202, and the top of the feed pipe 203 is funnel-shaped. Under the action of the self-gravity of the copper materials, guided by the feed pipe 203, the copper materials fall vertically onto the top of the limiting frame 204 for convenient transfer. The funnel shape is conducive to承接 and guiding the copper columns, preventing the copper columns from falling outside the feed pipe 203 and affecting the practicality of the device.

[0046] Refer to Figures 1-5 , in the above embodiment, the longitudinal section of the pushing plate 8 is in a "ji" shape, and the pushing plate 8 is slidably connected to the containing frame 3. Through the "ji" shape setting, the pushing plate 8 can slide outside the containing frame 3 and will not interfere with other components, and can also be guided and limited by the outer wall of the containing frame 3 to prevent the pushing plate 8 from shifting and affecting the practicality.

[0047] Embodiment 2: In order to facilitate the staff to align the stuck copper materials, Embodiment 2 is improved on the basis of Embodiment 1. Refer to Figure 6An observation port 14 is provided on one side of the guide box 12. The staff can observe the condition of the copper material inside the guide box 12 through the observation port 14. At the same time, when the copper material is misaligned and stuck, the staff can use tools to reach into the guide box 12 through the observation port 14 to straighten the stuck copper material. The operation is simple and quick.

[0048] The implementation principle of this utility model is as follows: Workers pour batches of cut copper material into the holding frame 3. Due to the inclination of the bottom of the holding frame 3, the copper material rolls to the angle between the sorting plate 5 and the inner wall. The control panel 13 is activated to execute the program, causing the output end of the first hydraulic cylinder 4 to drive the sorting plate 5 upward, pushing the copper material within the angle into the sorting trough 9. Due to its own weight, the copper material slides along the inclined surface of the sorting plate 5 into the sorting trough 9, completing the posture correction. The output end of the second hydraulic cylinder 6 drives the pusher plate 8 to push the copper material in the sorting trough 9 into the guide box 12. The limiting plate 10 blocks the copper material. To prevent slippage, when the guide box 12 is filled with three copper materials, the pressure sensor 7 detects the thrust threshold, and the second hydraulic cylinder 6 retracts to align the notch 11 with the guide box 12. The copper material falls through the guide box 12 into the feed pipe 203. The copper material in the feed pipe 203 falls vertically to the top of the limit frame 204. The third hydraulic cylinder 201 drives the limit frame 204 to move backward, and the copper material falls into the clamp 205. Then the limit frame 204 moves forward to the top of the mold, and the copper material falls into the punching position to wait for stamping. At the same time, the next copper material falls to the top of the limit frame 204, and the cycle continues.
