Description

Technical Field

[0001] This utility model relates to the field of conveying mechanism technology, and more specifically, to a wire clamping circulating conveying mechanism. Background Technology

[0002] Wire harnesses are often used to connect electronic components and circuit boards. Existing wire harnesses generally include components such as cables, terminals, and housings. The processing of wire harnesses is usually done manually, resulting in low production efficiency and an inability to guarantee the quality of the wire harnesses. In order to improve production efficiency and product quality, some machines such as wire stripping machines, terminal crimping machines, and housing insertion machines have appeared on the market. However, these machines are all independent, and workpieces need to be manually transported to different machines for processing. It is impossible to use an automated circulating conveyor mechanism to transport workpieces to different workstations or machines for assembly line operation, resulting in low production efficiency.

[0022] Please refer to Figure 1 , Figure 2 and Figure 3 The present invention provides a wire clamping and circulating conveying mechanism, including a conveying bracket 1, a chain circulating retainer 2, a drive wheel 3, a circulating conveying chain 4, a circulating conveying drive device 5, and a wire clamping clamp 6, etc. The components of this embodiment will be described in detail below with reference to the accompanying drawings.

[0023] like Figure 1 and Figure 3 As shown, the chain circulation retainer 2 is mounted on the conveyor bracket 1. The chain circulation retainer 2 can be configured as an elongated oval (i.e., waist-shaped). The outer periphery of the chain circulation retainer 2 is provided with a concave chain track groove 21. The chain track groove can preferably be configured as a cross groove or a T-shaped groove.

[0024] like Figure 4 and Figure 5 As shown, the circulating conveyor chain 4 can be formed by hinged together a number of chain joints 41 in sequence. Chain rollers 42 are provided on both sides of the connection between two adjacent chain joints 41. The chain joints 41 and chain rollers 42 can move within the chain track groove 21.

[0025] like Figure 3 and Figure 4 As shown, the drive wheel 3 is installed at one end of the chain circulation retainer 2. The outer periphery of the drive wheel 3 is provided with several roller slots 31. The circulation conveying drive device 5 is connected to the drive wheel 3 and drives it to rotate. The drive wheel 3 can drive the circulation conveying chain 4 to rotate in a cycle through the locking cooperation between its roller slots 31 and the chain rollers 42.

[0026] In this embodiment, the circulating conveying drive device 5 may include an existing T-shaped steering gear 51, a reducer 52, and a motor 53. The motor 53 can be connected to the steering gear 51 via the reducer 52, and the output shaft of the steering gear 51 is connected to the drive wheel 3. Of course, in other embodiments, the circulating conveying drive device 5 may also be directly configured as a motor or a motor + reducer.

[0027] like Figure 4 and Figure 5 As shown, the feeder clamps 6 are respectively installed on each chain joint 41. Each feeder clamp 6 may include a clamping frame 61, a movable seat 62, a clamping spring 63, an upper clamp 64, and a lower clamping block 65. The clamping frame 61 is installed on each chain joint 41, and the main body of the clamping frame 61 can preferably be configured in an H-shape. The movable seat 62 is movably installed on the clamping frame 61. The clamping spring 63 is installed between the clamping frame 61 and the movable seat 62. The upper clamp 64 is installed on a column of the clamping frame 61, and the lower clamping block 65 is installed on top of the movable seat 62 and located below the upper clamp 64. When clamping cables, a single feeder clamp 6 can clamp several cables at once.

[0028] Better, such as Figure 5 As shown, a baffle 8 can also be added between the conveyor clamp 6 and the chain joint 41.

[0029] In this embodiment, the conveyor clamp 6 is normally in a closed state. In order to enable it to open at the corresponding workstation, the production line can also be equipped with an opening mechanism 7. The opening mechanism 7 can be located on one side of the designated conveyor clamp 6 (such as on one side of the conveyor clamp at the loading and / or unloading workstation). The opening mechanism 7 can be connected to the circulating conveyor drive device 5 through the cam transmission assembly 8.

[0030] like Figure 6 As shown, the clamping mechanism 7 may include a clamping block 71 and a clamping block lifting slide 72. The clamping block 71 and the clamping block lifting slide 72 are slidably connected. The clamping block 71 can be connected to the main rotating shaft 9 through the cam transmission assembly 8. The main rotating shaft 9 is connected to the motor of the circulating conveying drive device 5 through a transmission assembly such as a chain + sprocket or a synchronous belt + synchronous pulley.

[0031] Of course, in other embodiments, the main rotating shaft 9 can also be directly connected to other motors.

[0032] The cam transmission assembly 8 may include a drive cam 81, a rocker arm support 82, a drive rocker arm 83, a drive bearing 84, and a drive link 85. The drive cam 81 is mounted on the main rotating shaft 9. One end of the drive rocker arm 83 is hinged to the rocker arm support 82, and the other end of the drive rocker arm 83 is hinged to the drive link 85. The drive link 85 is connected to the clamping block 71. The drive bearing 84 is mounted on the drive rocker arm 83 and rolls along the outer edge of the drive cam 81. The motor of the circulating conveying drive device 5 can drive the drive cam 81 to rotate through the main rotating shaft 9, thereby causing the drive rocker arm 83 to swing. In turn, the drive link 85 and the clamping block 71 move up and down through the drive rocker arm 83.

[0033] like Figure 7 As shown, when the conveyor clamp 6 rotates to the position of the clamping mechanism 7, the clamping block 71 can press down the movable seat 62 of the conveyor clamp 6, causing the upper clamp 64 and the lower clamp 65 to separate, thereby enabling the conveyor clamp 6 to open.

[0034] Of course, in other embodiments, if the wire clamp 6 is a pneumatic clamp or an electric clamp, the clamp opening mechanism 7 may not be added, depending on actual needs.

[0035] In summary, the present invention has a reasonable structural design, which can realize cyclic conveying operation. Each conveying clamp can hold multiple cables at the same time for transportation, which greatly improves production efficiency. Its operation is stable and reliable, and it is convenient to carry out assembly line processing with the machine it is paired with.

[0036] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
