Description

Technical Field

[0001] This invention relates to a terminal feeding and cutting device, and more particularly to a terminal strip cutting and separating device. Background Technology

[0002] Currently, electrical wires are widely used in signal transmission and power connections for computers, home appliances, communication equipment, and digital devices. To facilitate convenient and quick connection of electrical circuits, terminal blocks are commonly used. Terminal blocks come in various types, including single-hole, multi-hole, plug-in, and hook types, and are made of materials such as silver-plated copper, zinc-plated copper, copper, aluminum, and iron. They are primarily used for transmitting electrical signals or conducting electricity. When fixing and connecting wire terminals, a terminal crimping machine is generally used. This machine utilizes a power-driven mechanism to move a punch up and down, pressing the terminal and wire end together, causing localized deformation and tightly fastening them together. However, the wire crimping process needs to be completed according to a set procedure, requiring terminal conveying. Currently, existing multi-station terminal crimping machines integrate the terminal conveying mechanism with the crimping die, cutting off the waste strip after crimping one terminal. This necessitates multiple sets of terminal conveying and crimping die combinations for each crimping position on a single multi-station terminal crimping machine, resulting in high cost, complex structure, and large space occupation. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a terminal strip cutting and separating device that can cut terminal strip into individual terminals, and which is simple in structure, low in cost, and easy to assemble and debug, in order to overcome the shortcomings of the prior art.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution.

[0005] A terminal strip cutting and separating device includes a support, on which a conveying platform for conveying terminal strips is fixed; a cutter assembly is provided near the discharge end of the conveying platform, and a cutter drive mechanism is provided on the support, the cutter drive mechanism being used to drive the cutter assembly to move and cut the connection between two adjacent terminals in the terminal strip; a conveying pusher is provided above the conveying platform, and a pusher drive mechanism is provided on the support, the pusher drive mechanism being used to drive the conveying pusher to move back and forth and convey the terminal strip forward, the forward and backward movement stroke of the conveying pusher being equal to the distance between the center lines of two adjacent terminals.

[0008] Preferably, a follow-up pressing arm is fixedly connected to the outer side of the lifting frame, and a pressing head is fixed on the follow-up pressing arm.

The conveying push block is fixed to the bottom of the front end of the swing block. When the second cylinder drives the conveying push block to move forward, the conveying push block and the terminal strip interlock and push the terminal strip forward. When the second cylinder drives the conveying push block to move backward, the conveying push block slides backward relative to the terminal strip.

[0012] Preferably, the lower end of the conveying pusher has a wedge-shaped tip, and the terminal strip has through holes evenly distributed along its length. The distance between the center points of two adjacent through holes is equal to the distance between the center lines of two adjacent terminals.

[0013] Preferably, a guide plate is fixed on the conveying platform, and a guide groove extending in the front-back direction is formed on the guide plate. The through hole is aligned with the guide groove, and the lower end of the wedge-shaped tip is located inside the guide groove.

[0014] Preferably, the conveying platform is provided with a flattening mechanism for simultaneously pressing multiple terminals, and the side of the conveying platform is provided with a detachable inverted L-shaped buckle plate. The horizontal part of the inverted L-shaped buckle plate presses on the top of the terminal strip, and the vertical part of the inverted L-shaped buckle plate is provided with an adjusting handle for adjusting the clamping degree of the L-shaped buckle plate.

In specific execution, the cutter driving mechanism drives the cutter assembly to move, thereby cutting off the connection between two adjacent terminals in the terminal strip. The cut terminal is picked up by the gripper assembly of the downward station transverse conveying mechanism. Then, the push block driving mechanism drives the conveying push block to move forward. Since the forward and backward movement of the conveying push block is equal to the distance between the center lines of two adjacent terminals, when the conveying push block moves forward one step, it accurately pushes the next terminal on the terminal strip to the cutting position of the cutter assembly, thereby realizing the function of automatic cutting and conveying of the terminal strip. Compared with the prior art, this invention can not only cut the terminal strip into individual terminals, but also has a simple structure, low cost, and is easy to assemble and debug in practical applications.

[0020] The present invention will now be described in more detail with reference to the accompanying drawings and embodiments.

[0021] This invention discloses a terminal strip cutting and separating device, combined with Figures 1 to 4 As shown, it includes a support 1, on which a conveying platform 2 for conveying terminal material strip 100 is fixed;

[0022] The conveying platform 2 is provided with a cutter assembly 3 near the discharge end, and the support 1 is provided with a cutter drive mechanism 4. The cutter drive mechanism 4 is used to drive the cutter assembly 3 to move and cut off the connection between two adjacent terminals 101 in the terminal strip 100.

[0023] The conveying platform 2 is provided with a conveying pusher 5 above it, and the support 1 is provided with a pusher driving mechanism 6. The pusher driving mechanism 6 is used to drive the conveying pusher 5 to move back and forth and convey the terminal material strip 100 forward. The forward and backward movement stroke of the conveying pusher 5 is equal to the distance between the center lines of two adjacent terminals 101.

[0024] In the above-described device, the pusher drive mechanism 6 and the cutter drive mechanism 4 are sequentially arranged along the conveying direction of the conveying platform 2. During specific execution, the cutter drive mechanism 4 drives the cutter assembly 3 to move, thereby cutting off the connection between two adjacent terminals 101 in the terminal strip 100. The cut terminal 101 is picked up by the gripper assembly of the downward station transverse conveying mechanism. Then, the pusher drive mechanism 6 drives the conveying pusher 5 to move forward. Since the forward and backward movement of the conveying pusher 5 is equal to the distance between the center lines of two adjacent terminals 101, when the conveying pusher 5 moves forward one step, it accurately pushes the next terminal 101 on the terminal strip 100 to the cutting position of the cutter assembly 3, thereby realizing the function of automatically cutting and conveying the terminal strip. Compared with the prior art, the present invention can not only cut the terminal strip into individual terminals, but also has a simple structure, low cost, and is easy to assemble and debug in practical applications.

[0025] To achieve reliable cutting, this embodiment preferably provides upper and lower cutters. Specifically, the cutter assembly 3 includes an upper cutter 30 and a lower cutter 31. The lower cutter 31 is fixedly connected to the conveying platform 2, the upper cutter 30 is located above the conveying platform 2, the terminal strip 100 is located between the upper cutter 30 and the lower cutter 31, and the cutter drive mechanism 4 is used to drive the upper cutter 30 to move up and down.

[0026] In this embodiment, the upper cutter 30 is preferably driven to move up and down to perform the cutting function. Please refer to [link / reference]. Figure 2 and Figure 3 The cutter drive mechanism 4 includes a first cylinder 40, and a lifting frame 41 is fixedly connected to the telescopic rod at the lower end of the first cylinder 40. The upper cutter 30 is fixed on the lifting frame 41.

[0027] As a preferred embodiment, a follower pressing arm 42 is fixedly connected to the outer side of the lifting frame 41, and a pressing head 43 is fixed on the follower pressing arm 42. Further, the follower pressing arm 42 is an L-shaped arm. The function of this mechanism is that, when the terminal 101 is cut off, the follower pressing arm 42 simultaneously presses down the gripper assembly of the terminal horizontal feeding mechanism (not shown), ensuring that the terminal 101 remains horizontal during the cutting process and preventing terminal deformation.

[0028] In order to better install and fix the lower cutter 31, in this embodiment, the conveying platform 2 is provided with a cutter receiving port 20, and the lower cutter 31 is fixed in the cutter receiving port 20.

[0029] For details on the specific components of the feeding mechanism, please refer to [link / reference]. Figure 4The push block driving mechanism 6 includes a second cylinder 60. A front and rear movement bracket 61 is fixed on the telescopic rod at the front end of the second cylinder 60. A swing block 62 is provided below the front and rear movement bracket 61. The rear end of the swing block 62 is hinged to the lower end of the front and rear movement bracket 61. A spring 63 is provided at the connection between the swing block 62 and the front and rear movement bracket 61 to drive the front end of the swing block 62 to swing downward. The conveying push block 5 is fixed to the bottom of the front end of the swing block 62. When the second cylinder 60 drives the conveying push block 5 to move forward, the conveying push block 5 and the terminal material strip 100 are interlocked and push the terminal material strip 100 forward. When the second cylinder 60 drives the conveying push block 5 to move backward, the conveying push block 5 slides backward relative to the terminal material strip 100.

[0030] Furthermore, the lower end of the conveying pusher 5 is formed with a wedge-shaped tip 50, and the terminal strip 100 is evenly distributed with through holes 102 along its length. The distance between the center points of two adjacent through holes 102 is equal to the distance between the center lines of two adjacent terminals 101. When the second cylinder 60 drives the conveying pusher 5 to move forward, the wedge-shaped tip 50 is engaged in the through holes 102 and applies a forward thrust to the terminal strip 100.

[0031] When the second cylinder 60 drives the conveying push block 5 to move backward, the conveying push block 5 slides backward relative to the terminal strip 100 so that the inclined surface of the wedge tip 50 abuts against the edge of the through hole 102 and the wedge tip 50 is lifted as the conveying push block 5 slides backward, and the wedge tip 50 exits the through hole 102.

[0032] In the above structure, the wedge-shaped tip 50 at the lower end of the conveying pusher 5 is used to engage with the through hole 102. When the second cylinder 60 drives the conveying pusher 5 forward, under the elastic force applied by the spring 63, the wedge-shaped tip 50 remains engaged in the through hole 102, thereby applying a forward thrust to the terminal strip 100. When the second cylinder 60 drives the conveying pusher 5 backward, the swing block 62 overcomes the elastic force applied by the spring 63, and the wedge-shaped tip 50 slides backward relative to the terminal strip 100 to the next through hole 102 behind it. After the front-end cutting action is completed, the forward pushing action is repeated.

[0033] To ensure that the wedge-shaped tip 50 is aligned with the through hole 102, in this embodiment, a guide plate 21 is fixed on the conveying platform 2, and a guide groove 22 extending in the front-back direction is provided on the guide plate 21. The through hole 102 is aligned with the guide groove 22, and the lower end of the wedge-shaped tip 50 is located in the guide groove 22.

[0034] As a preferred embodiment, the conveying platform 2 is equipped with a flattening mechanism 7 for simultaneously pressing down multiple terminals 101. The side of the conveying platform 2 is provided with a detachable inverted L-shaped clamping plate 8. The horizontal portion of the inverted L-shaped clamping plate 8 presses down on the terminal strip 100, and the vertical portion of the inverted L-shaped clamping plate 8 is provided with an adjusting handle 9 for adjusting the clamping force of the L-shaped clamping plate 8. The flattening mechanism 7 and the inverted L-shaped clamping plate 8 are used to keep the terminal strip 100 flat during conveying, thereby achieving precise cutting and reliable separation of the terminal strip.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions or improvements made within the technical scope of the present invention should be included within the scope of protection of the present invention.
