Description

Technical Field

[0001] The utility model relates to the field of crimping devices, in particular to a crimping and cutting device for ultrasonic welding harness terminals. Background Art

[0002] Terminals are components that connect batteries to external conductors. In electrical engineering, terminals mostly refer to wiring terminals, also called wiring harness terminals. There are single-hole and hook types, etc. Their main function is to transmit electrical signals or conduct electricity. With the widespread use of ultrasonic welding technology in high-power wiring harness terminal connectors and higher requirements for product quality, wiring harness terminals require crimping of insulating crimping wings while using ultrasonic welding to ensure the stability of ultrasonic welding of wiring harness terminals.

[0003] Most of the existing ultrasonic welding wire harness terminal crimping equipment are mostly composed of components such as a workbench, an ultrasonic welding device and a placement block. The worker cuts off the protective rubber sleeve on the outside of the wire head that needs to be welded and compacted, places it on the end face of the placement block to fix it, and pushes it into the ultrasonic welding device so that it fixes the wire harness terminal on the surface of the wire harness.

[0004] However, during use, most of the existing ultrasonic welding harness terminal compaction equipment requires workers to manually remove the protective cover on the surface of the harness using tools such as circular cutters, and then place it into the end face of the placement block to fix it, so as to facilitate the subsequent welding of the terminals. In addition, in the process of removing the rubber protective cover, it is difficult for workers to collect it due to force, resulting in scattered rubber protective covers remaining on the end face of the workbench, affecting the cleanliness of the workbench and the subsequent welding of the terminals. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a crimping and cutting device for ultrasonically welded wire harness terminals to solve the technical problems mentioned in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a crimping and cutting device for ultrasonic welding wire harness terminals, comprising a workbench and an ultrasonic welding device, a fixed block is fixedly installed at one end of the workbench, and a placement block is movably installed inside the fixed block, a driving device is fixedly installed at one end of the placement block, and an electric cutter is movably installed inside the driving device, a movable block is movably installed at one end of the placement block, and a connecting rod is movably installed inside the movable block, a clamp is fixedly installed at one end of the connecting rod, and a spring is sleeved on the outside of the connecting rod, the clamp and the movable block are connected by a spring, a sliding rod is fixedly installed at one end of the movable block, a baffle is fixedly installed at one end of the workbench, and a guide groove for guiding the sliding rod is opened inside the baffle, and an auxiliary component for controlling the position of the clamp is fixedly installed at one end of the baffle.

[0007] By adopting the above technical scheme, by providing components such as a clamp, a connecting rod, a spring, a sliding rod, a guide groove and a top block, when a worker uses the device to weld the wiring harness terminal, he only needs to place the wiring harness inside the placement block and restrict it to a certain extent by the clamp, and then start the driving device so that the electric cutter completes the cutting of the rubber protective cover on its external end face. When it is pushed into the ultrasonic welding device for welding, the movable block is squeezed by the driving device and moved upward by the guide position of the guide groove. After it reaches a certain height, it contacts the top block, and the clamp is controlled to move to both sides. The cut rubber protective cover can be automatically taken out and dropped into the storage box through the discharge port for collection. Compared with the traditional manual collection by workers, the device has higher cutting and collection efficiency, greatly improves its overall work intensity, effectively ensures the surface cleanliness of the workbench, and ensures that the rubber protective cover will not affect the welding process. At the same time, it is convenient for subsequent workers to reuse the rubber and reduce production costs.

[0008] The utility model is further configured such that the auxiliary component includes an extension plate and a top block, the extension plate is fixedly installed at one end of the baffle, and a top block matching the clamp is fixedly installed in the middle of the extension plate, the top block is in the shape of an inverted triangle, and one side end face of the top block is in the shape of an arc.

[0009] By adopting the above technical solution, the baffle provides support and fixation for the extension plate, and the fixedly installed top block ensures that its position will not change when it is squeezed by the clamp. The inverted triangle and one side end face are arranged in an arc shape, so that when the clamp is moved and released, the position continues to move upward, and the top block will open the clamp, thereby releasing and removing the rubber protective cover clamped by it, and ejecting it from the inside of the clamp, so as to automatically collect and remove it, eliminating the need for subsequent workers to remove it, thereby improving its overall welding efficiency.

[0010] The utility model is further configured that a storage box is movably installed inside the workbench, and a handle is fixedly installed at one end of the storage box, a limit block is fixedly installed at one end of the storage box, and a second limit groove matching the limit block is opened inside the workbench.

[0011] By adopting the above technical solution, the movably installed storage box allows workers to take it out from the inside of the workbench by pulling the handle to clean the inside. The limit block cooperates with the second limit groove to effectively limit the moving distance of the storage box inside the workbench, preventing it from detaching from the workbench and affecting its collection of the rubber protective cover.

[0012] The utility model is further configured that a movable groove for the clamp to move is opened inside the placement block, a discharge port for discharging waste is opened inside the workbench, and both side end surfaces of the discharge port are arranged in an arc shape.

[0013] By adopting the above technical solution, the movable groove provides a certain space for the clamp to move inside the placement block, so that the clamp can better fix and restrict the wiring harness. The feed opening allows the cut rubber protective cover to fall into the storage box through it, making it convenient to collect and reuse it.

[0014] The utility model is further configured such that a first limiting rod is fixedly installed at one end of the placing block, and a first limiting groove for limiting the first limiting rod is opened inside the fixing block, and a limiting plate is fixedly installed at one end of the connecting rod, and the diameter of the limiting plate is greater than the diameter of the connecting rod.

[0015] By adopting the above technical solution, the first limit rod cooperates with the first limit groove to effectively control the moving direction and distance of the placement block inside the fixed block, and imposes certain restrictions on it to ensure its welding effect on the wiring harness terminal. The diameter of the limit plate is larger than the diameter of the connecting rod, which can effectively ensure that the connecting rod will not be separated from the movable block due to the elastic force of the spring, thereby ensuring the normal operation of the equipment and improving the reliability of the equipment.

[0016] The utility model is further configured such that the movable blocks, connecting rods, springs, clamps, limit plates, slide bars and guide grooves are all symmetrically arranged in two groups, and one side end faces of the two groups of clamps are both arc-shaped, and the two groups of movable blocks, connecting rods, springs, clamps, limit plates, slide bars and guide grooves are symmetrically arranged.

[0017] By adopting the above technical solution, workers can better control the overall position of the movable block when moving the placement block, and prevent the movable block from causing the position of the clamp to shift. One side end face of the two sets of clamps is set in an arc shape, so that they can better move to both sides when squeezed by the wire harness, and then reset through the spring to better limit and fix, effectively ensuring the welding effect of the wire harness terminal.

[0018] In summary, the utility model mainly has the following beneficial effects:

[0019] The utility model is provided with components such as a clamp, a connecting rod, a spring, a sliding rod, a guide groove and a top block, so that when a worker uses the device to weld a wiring harness terminal, he only needs to place the wiring harness inside the placement block, restrict it to a certain extent through the clamp, and then start the driving device so that the electric cutter completes the cutting of the rubber protective cover on its external end face. When it is pushed into the ultrasonic welding device for welding, the movable block is squeezed by the driving device and moves up the guide position of the guide groove, and contacts the top block after it reaches a certain height. The clamp is controlled to move to both sides, and the cut rubber protective cover can be automatically taken out, dropped into the inside of the storage box through the discharge port, and collected. Compared with the manual collection of traditional workers, the present device has higher cutting and collection efficiency, greatly improves its overall working intensity, effectively ensures the surface cleanliness of the workbench, ensures that the rubber protective cover will not affect the welding process, and is convenient for subsequent workers to reuse the rubber, thereby reducing production costs.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0026] The following describes an embodiment of the utility model based on its overall structure.

[0027] A crimping and cutting device for ultrasonic welding wiring harness terminals, such as Figure 1-4As shown, it includes a workbench 1 and an ultrasonic welding device 2, a fixed block 3 is fixedly installed at one end of the workbench 1, and a placement block 4 is movably installed inside the fixed block 3, a driving device 7 is fixedly installed at one end of the placement block 4, and an electric cutter 8 is movably installed inside the driving device 7, a movable block 9 is movably installed at one end of the placement block 4, and a connecting rod 10 is movably installed inside the movable block 9, a clamp 12 is fixedly installed at one end of the connecting rod 10, and a spring 11 is sleeved on the outside of the connecting rod 10, the clamp 12 and the movable block 9 are connected to the spring 11, a sliding rod 14 is fixedly installed at one end of the movable block 9, a baffle 18 is fixedly installed at one end of the workbench 1, and a guide groove 15 for guiding the sliding rod 14 is opened inside the baffle 18, and an auxiliary component for controlling the position of the clamp 12 is fixedly installed at one end of the baffle 18. When using this equipment, workers put the wire harness to be welded into The inner groove of the placement block 4 is placed so that it passes through the clamp 12, and the wiring harness is initially fixed and restricted by the clamp 12. After the driving device 7 is started to make the electric cutter 8 separate the rubber protective cover at the outer end of the wiring harness from the copper wire inside it, the placement block 4 is pushed to enter the ultrasonic welding device 2. During the movement of the placement block 4, the driving device 7 will squeeze the overall position of the movable block 9, so that the movable block 9 moves up along the guide groove 15, and the clamp 12 is controlled to drive the rubber protective cover that has been separated from the copper wire inside the wiring harness to separate together. As the movable block 9 continues to move upward, the top block 17 squeezes the clamp 12 to move and separate it, and the rubber protective cover is no longer restricted, so that it falls through the discharge port 24 into the storage box 20, and is collected for subsequent cleaning and reuse, effectively improving its overall work efficiency and reducing the work intensity of workers.

[0028] See also Figure 2 - Figure 3 The auxiliary components include an extension plate 16 and a top block 17. The extension plate 16 is fixedly installed at one end of the baffle 18, and a top block 17 matching the clamp 12 is fixedly installed in the middle of the extension plate 16. The top block 17 is in the shape of an inverted triangle, and one side end face of the top block 17 is in the shape of an arc. The baffle 18 provides support and fixation for the extension plate 16. The fixedly installed top block 17 ensures that its position will not change when it is squeezed by the clamp 12. The inverted triangle and one side end face are in the shape of an arc, so that when the clamp 12 is moved and released, its position continues to move upward, and the top block 17 will open the clamp 12, thereby releasing the rubber protective cover clamped by it and removing it, and ejecting it from the inside of the clamp 12, so as to automatically collect and remove it, eliminating the need for subsequent workers to remove it, and improving its overall welding efficiency.

[0029] See also Figure 1 - Figure 4A storage box 20 is movably installed inside the workbench 1, and a handle 22 is fixedly installed at one end of the storage box 20. A limiting block 23 is fixedly installed at one end of the storage box 20, and a second limiting groove 21 matching the limiting block 23 is opened inside the workbench 1. The movably installed storage box 20 allows workers to take it out of the workbench 1 by pulling the handle 22 to clean the inside. The limiting block 23 cooperates with the second limiting groove 21 to effectively limit the moving distance of the storage box 20 inside the workbench 1, preventing it from detaching from the workbench 1 and affecting its collection of the rubber protective cover.

[0030] See also Figure 3 - Figure 4 A movable groove 19 for the clamp 12 to move is provided inside the placement block 4, and a discharge port 24 for discharging waste is provided inside the workbench 1, and the end surfaces on both sides of the discharge port 24 are both arc-shaped. The movable groove 19 provides a certain space for the clamp 12 to move inside the placement block 4, so that the clamp 12 can better fix and limit the wire harness. The discharge port 24 allows the cut rubber protective cover to fall into the storage box 20 through it, which is convenient for its collection and reuse.

[0031] See also Figure 1 - Figure 4 A first limiting rod 5 is fixedly installed at one end of the placement block 4, and a first limiting groove 6 for limiting the first limiting rod 5 is opened inside the fixed block 3. A limiting plate 13 is fixedly installed at one end of the connecting rod 10, and the diameter of the limiting plate 13 is larger than the diameter of the connecting rod 10. The first limiting rod 5 cooperates with the first limiting groove 6 to effectively control the moving direction and distance of the placement block 4 inside the fixed block 3, and imposes certain restrictions on it to ensure its welding effect on the wiring harness terminal. The diameter of the limiting plate 13 is larger than the diameter of the connecting rod 10, which can effectively ensure that the connecting rod 10 will not be separated from the movable block 9 due to the elastic force of the spring 11, thereby ensuring that the equipment can operate normally and improving the reliability of the equipment.

[0032] See also Figure 1 - Figure 4 The movable block 9, connecting rod 10, spring 11, clamp 12, limit plate 13, slide bar 14 and guide groove 15 are all symmetrically arranged in two groups, and one side end faces of the two groups of clamps 12 are arc-shaped. The two groups of symmetrically arranged movable blocks 9, connecting rod 10, spring 11, clamp 12, limit plate 13, slide bar 14 and guide groove 15 enable workers to better control the overall position of the movable block 9 when moving the placement block 4, and prevent the movable block 9 from driving the position of the clamp 12 to shift. One side end faces of the two groups of clamps 12 are arc-shaped, so that they can better move to both sides when squeezed by the wiring harness, and then reset by the spring 11 to better limit and fix, effectively ensuring the welding effect of the wiring harness terminal.

[0033] The working principle of the utility model is as follows: when using the device, a worker places the wire harness to be welded into the inner groove of the placement block 4, passes it through the clamp 12, and preliminarily fixes and restricts the wire harness through the clamp 12. After starting the driving device 7 so that the electric cutter 8 separates the rubber protective cover at the outer end of the wire harness from the copper wire inside it, the placement block 4 is pushed to enter the ultrasonic welding device 2, and the welding of the wire harness terminal is completed through the ultrasonic welding device 2. During the movement of the placement block 4, the driving device 7 squeezes the overall position of the movable block 9, so that the movable block 9 moves up along the guide groove 15 opened at one end of the baffle 18, and controls the rubber protective cover clamped by the clamp 12. It is separated from the copper wire inside the wiring harness, and drives the rubber protective cover that has been separated from the copper wire inside the wiring harness to be separated together. After it moves to a certain height as a whole, the top block 17 enters the middle of the two groups of clamps 12. As the movable block 9 continues to move upward, the clamp 12 is squeezed and displaced by the top block 17 to separate it, and the rubber protective cover is no longer restricted, so that it falls through the discharge port 24 into the interior of the storage box 20, and is collected for subsequent cleaning and reuse. After completing the ultrasonic welding of the wiring harness terminal, the worker pulls the placement block 4 to reset it. After the extrusion is lost, the movable block 9 is affected by gravity to drive the clamp 12 and other components to reset, and then the welding of the next group of wiring harnesses can be carried out.

The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contributions as needed without departing from the principles and purpose of the utility model. However, as long as they are within the scope of the claims of the utility model, they are protected by patent law.
