In the existing technology, the assembly is mainly done manually. After the assembly is completed, the terminals are placed between electrodes for soldering. The operation is relatively cumbersome and the production efficiency is low. Moreover, due to the low production volume and low profit of the terminals, it is not possible to design dedicated automated equipment to achieve automated production. Therefore, it is necessary to design a semi-automated equipment with a simple structure and low cost to assist manual terminal assembly and improve the soldering efficiency of the terminals.

[0008] The present invention is further configured such that: the sealing assembly includes a sealing cylinder fixedly arranged along the vertical direction and a telescopic end fixedly connected to the sealing cylinder, for sealing the conveying groove or the separation groove.

[0009] The present invention is further configured such that: the width of the feeding trough is between 1 and 1.5 times the diameter of the electronic wire, and the feeding trough and the conveying trough are connected in an arc shape; the diameter of the storage trough is not less than 2 times the diameter of the electronic wire; the end of the conveying trough, the feeding trough, and the storage trough away from the terminal positioning groove is opened, and the welding end of the electronic wire abuts against the inner wall of the conveying trough, the feeding trough, and the storage trough.

[0012] In summary, this utility model has the following beneficial effects:

[0013] 1. By setting a hopper assembly and a separation assembly assembly on a welding base, the hopper assembly has a conveying trough for single-layer electronic wire arrangement in a horizontal feeding seat and a feeding trough and a storage trough in a storage seat. Electronic wires are batch-loaded into the storage trough of the storage seat, and under gravity, they slide down the feeding trough into the conveying trough of the horizontal feeding seat. Since the width of the feeding trough is limited to 1-1.5 times the diameter of the electronic wire, this ensures that the electronic wires are conveyed in a single-layer, orderly arrangement within the conveying trough. The separation assembly assembly has a separation seat in contact with the horizontal feeding seat and a separation trough within it. When material needs to be retrieved, the separation trough of the separation seat aligns with the conveying trough. At this time, the sealing assembly at the end of the conveying trough opens, and after the electronic wire enters the separation trough, the sealing assembly at the entrance of the separation trough closes to block subsequent electronic wires. A push cylinder pushes the separation seat to move in a direction perpendicular to the U-shaped connecting groove. Under the guidance of the guide block's guide groove, the electronic wire is precisely inserted into the U-shaped terminal. Assembly is completed by placing the terminals in the shaped connecting groove. After assembly, the welding electrode block directly welds the terminals. The terminal assembly process only requires manual placement of the terminals into the positioning groove, reducing the tedious manual insertion and removal of electronic wires, improving production efficiency, and avoiding problems such as uneven electronic wire arrangement and inconsistent insertion depth caused by manual operation, thus improving the product qualification rate. The structure is simple and the production cost is low. Attached Figure Description

[0020] The present invention will be further described in detail below with reference to the accompanying drawings.

[0021] Example:

[0022] refer to Figures 1 to 5 A semi-automatic terminal assembly and welding device includes a welding base 1, a terminal positioning groove 2 for positioning terminals 9 on the welding base 1, welding electrode blocks 3 for welding terminals 9 fixedly connected to both the front and back of the welding base 1, when an electronic wire 10 is inserted into the U-shaped connecting groove 11 of the terminal 9, the welding electrode block 3 discharges to melt the solder, thereby welding the terminal 9 and the electronic wire 10 together. A hopper assembly 4 for storing electronic wires 10 and a separation assembly assembly 5 for separating several electronic wires 10 from the hopper assembly 4 and pushing the electronic wires 10 into the U-shaped connecting groove 11 for assembly are also fixedly connected to the welding base 1, and an epoxy insulation board 8 for insulation is attached and fixedly connected to the surface of the welding base 1, the epoxy insulation board 8 can prevent the risk of leakage during welding and improve operational safety.

[0023] refer to Figure 2 and Figure 4 Specifically, the hopper assembly 4 includes a horizontal feeding seat 41 fixedly connected to the welding base 1 along the horizontal direction and a storage seat 42 fixedly connected to the horizontal feeding seat 41. A conveying trough 43 for conveying single-layer electronic wires 10 is formed horizontally within the horizontal feeding seat 41. A feeding trough 44 communicating with the conveying trough 43 and a storage trough 45 communicating with the feeding trough 44 are formed within the storage seat 42. A trough for closing the conveying trough 43 is fixedly connected to the end of the horizontal feeding seat 41 along the feeding direction. The sealing assembly 46 is used to block the electronic wire 10 from flowing out. The width of the feeding trough 44 is between 1 and 1.5 times the diameter of the electronic wire 10, and the feeding trough 44 and the conveying trough 43 are connected in an arc shape. The diameter of the storage trough 45 is not less than twice the diameter of the electronic wire 10. By placing the electronic wire 10 in batches into the storage trough 45 of the storage seat 42, the electronic wire 10 slides down through the feeding trough 44 into the conveying trough 43 of the horizontal feeding seat 41 under the action of gravity. Since the width of the feeding trough 44 is limited to 1 to 1.5 times the diameter of the electronic wire 10, it is ensured that the electronic wire 10 passes through the feeding trough 44 in a single layer and is arranged in the conveying trough 43 for conveying. The conveying trough 43, the feeding trough 44 and the storage trough 45 are open at the end away from the terminal positioning groove 2, and the welding end of the electronic wire 10 abuts against the inner wall of the conveying trough 43, the feeding trough 44 and the storage trough 45, thereby avoiding the problem of uneven arrangement of the electronic wire 10 caused by manual operation.

[0024] refer to Figure 2 and Figure 3Specifically, the separation assembly component 5 includes a separation seat 51 slidably connected to the welding base 1 along the opening direction perpendicular to the U-shaped connecting groove 11, and a pushing cylinder 52 fixedly connected to the horizontal feeding seat 41 for pushing the separation seat 51. A separation groove 53 is provided inside the separation seat 51 to accommodate several parallel single-layer electronic wires 10. The height of the separation groove 53 is equal to and aligned with the height of the conveying groove 43. In the initial state, the separation seat 51 is aligned and fitted with the horizontal feeding seat 41, and the separation groove 53 of the separation seat 51 is aligned with the conveying groove 43. A sealing component 46 is also fixedly connected to one end of the separation groove 53 near the hopper assembly 4 to close the entrance of the separation groove 53 to block the electronic wires 10 during assembly. When material needs to be removed, the sealing component 46 at the end of the conveying groove 43 opens, and after the electronic wires 10 enter the separation groove 53, the sealing component 46 at the entrance of the separation groove 53 closes to block subsequent electronic wires 10. The pushing cylinder 52 pushes the separation seat 51 along the opening direction perpendicular to the U-shaped connecting groove 11. The electronic wire 10 moves in the direction of the U-shaped connecting groove, and is precisely inserted into the U-shaped connecting groove of the terminal 9 under the guidance of the guide groove 7 of the guide block 6, thus completing the assembly. The sealing assembly 46 includes a sealing cylinder 461 fixedly arranged in the vertical direction and a sealing plate 462 fixedly connected to the telescopic end of the sealing cylinder 461 for sealing the conveying groove 43 or the separation groove 53. The sealing cylinder 461 drives the sealing plate 462 to rise and fall, thereby sealing the conveying groove 43 and the separation groove 53 to block the movement of the electronic wire 10. At the same time, it can also abut against the electronic wire 10 during the assembly process so that the electronic wire 10 can be smoothly inserted into the U-shaped connecting groove 11.

[0025] refer to Figure 5 Specifically, the welding base 1 has a guide block 6 fixedly connected at the opening of the U-shaped connecting groove 11 to guide the end of the electronic wire 10 into the U-shaped connecting groove 11. A guide groove 7 is provided in the guide block 6. The end of the guide groove 7 away from the U-shaped connecting groove 11 is set in an arc-shaped flare. The electronic wire 10 is accurately inserted into the U-shaped connecting groove of the terminal 9 under the guidance of the guide groove 7 of the guide block 6, so as to facilitate the assembly of the electronic wire 10.

[0026] Brief description of the usage process: By placing electronic wires 10 in batches into the storage trough 45 of the storage base 42, the electronic wires 10 slide down the feeding trough 44 under the action of gravity into the conveying trough 43 of the horizontal feeding base 41, so that the electronic wires 10 are arranged in a single layer in an orderly manner in the conveying trough 43 for conveying. When it is necessary to pick up the material, the separation trough 53 of the separation base 51 is aligned with the conveying trough 43. At this time, the sealing component 46 at the end of the conveying trough 43 opens. After the electronic wires 10 enter the separation trough 53, the sealing component 46 at the entrance of the separation trough 53 closes to block subsequent electronic wires 10. The push cylinder 52 pushes the separation base 51 to move in a direction perpendicular to the U-shaped connecting groove. Under the guidance of the guide groove 7 of the guide block 6, the electronic wires 10 are accurately inserted into the U-shaped connection groove of the terminal 9. Assembly is completed in the shaped connecting groove. After assembly, the welding electrode block 3 directly welds the terminal 9. After welding, the welded terminal 9 is manually removed. The push cylinder 52 drives the separation seat 51 to return to its original position. The sealing assembly 46 opens the conveying groove 43 and the separation groove 53 so that the electronic wire 10 can smoothly enter the separation groove 53.
