Description

Technical Field

[0001] The utility model relates to the technical field of wire harness assembly, in particular to a semi-automatic translation slide plate device for wire harness assembly. Background Art

[0002] At present, in order to reduce the turnover and buffering phenomenon between assembly stations in the manufacturing process of automobile wiring harnesses, most of them adopt the form of improving the connection tightness between stations, which is mainly achieved through manual conveying of slideways and row clamps or fully automatic lifting slides. The combination of slideways and row clamps is to set multiple row clamps on the slideway, and use the row clamps to slide on the slideway. The operation of the fully automatic lifting slide mainly relies on the friction force transmitted by the belt.

[0003] When it comes to the line joining operation with a large number of assembly stations, both the slideway and row clamp combination and the lifting slide plate method are unstable. The instability is mainly manifested in that the slideway and row clamp combination method has a large wear of the row clamp and the slideway during operation, which easily causes the slideway to deform and the slide plate row clamp to be unable to be pushed. This not only affects the service life of the slideway and the row clamp, but also there is a gap between the slideway and the row clamp, which poses a great quality risk of clamping the wire terminals. The fully automatic lifting slide plate method relies on belt transmission for transportation, which has insufficient precision control, is prone to slipping, abnormal equipment shutdown, and has poor operating stability. In addition, the lifting slide plate is connected as a whole and cannot be disassembled, which limits the number of pre-installed stations. Utility Model Content

Detailed Embodiments

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the core concept of the present invention and the following embodiments, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0027] Embodiment 1, a semi-automatic translation slide device for wire harness assembly, as Figure 1 and Figure 2As shown, it includes a first track 15 and a second track 16 separated by a track separation block 6 in the middle. A number of skateboard trolleys 14 are respectively connected to the first track 15 and the second track 16. A track-changing assembly for controlling the skateboard trolley 14 to change tracks between the first track 15 and the second track 16 is provided on the first track 15 and / or the second track 16. The skateboard trolley 14 is connected to the first track 15 through a transmission mechanism.

[0028] Specifically, the first track 15 and the second track 16 are two parallel straight tracks, and the middle parts of the two straight tracks are separated by the track separation block 6. The track-changing assembly is used to separate or connect the two ends of the first track 15 and the second track 16. When the skateboard trolley 14 moves to the end of the first track 15 driven by the transmission mechanism, the track-changing assembly connects the first track 15 and the second track 16. When the skateboard trolley 14 changes to the second track 16, the track-changing assembly separates the first track 15 and the second track 16. When the skateboard trolley 14 is manually dragged to the end of the second track 16, the track-changing assembly connects the first track 15 and the second track 16, and the skateboard trolley 14 returns from the second track 16 to the first track 15.

[0029] Further, as Figure 2 shown, the transmission mechanism includes a chain 3 driven by a motor 1 and a gear 2. The chain 3 is connected to the skateboard trolley 14 through a dial 5. The dial 5 is connected to the chain 3 through an extended pin shaft. The dial 5 drives a block 19 on the side of the skateboard trolley 14, thereby driving the skateboard trolley 14 to move horizontally along the first track 15. The running speed of the skateboard trolley 14 is mainly realized by adjusting the motor 1. The motor 1 is preferably a right-angle motor.

[0030] Further, as Figure 2 shown, both the first track and the second track are arranged on the same operation plane 17. The track-changing assembly includes a lifting cylinder 7 connected to the center line of the operation plane 17. The track separation block 6 is arranged in the middle of the center line of the operation plane 17, and the lifting cylinder 7 is arranged at both ends of the center line of the operation plane 17. The lifting cylinder 7 is electrically connected to a sensor for detecting the position of the skateboard trolley 14. Preferably, the operation plane 17 is a stainless steel plate.

[0031] Specifically, the lifting cylinder 7 is provided with a stopper, which can be connected to the first track 15 or the second track 16, or can be provided on both the first track 15 and the second track 16. The lifting cylinder 7 can be one or more. When there are multiple lifting cylinders 7, multiple lifting cylinders 7 are uniformly controlled; the lifting cylinder 7 separates the first track 15 and the second track 16 through the stopper, and the lifting cylinder 7 is connected to sensors provided at both ends of the first track 15 and the second track 16 through electrical signals. When the sensor detects that the skateboard trolley 14 moves to both ends of the first track 15 and the second track 16, the sensor controls the stopper of the lifting cylinder 7 to descend, and when the sensor detects that the skateboard trolley 14 changes the track, the sensor controls the stopper of the lifting cylinder 7 to rise. The sensor can be a position sensor, a color sensor, a distance sensor, or a gravity sensor. Furthermore, the distance sensor is provided on the side of the first track 15 and the second track 16 away from the track separation block 6.

[0032] Furthermore, if Figure 3 As shown, when the scooter 14 moves to the ends of the first track 15 and the second track 16, in order to avoid deformation or damage of the scooter 14 due to inertial impact force when the scooter 14 reaches the ends of the first track 15 and the second track 16 due to excessive moving speed, anti-collision blocks 20 are connected to the two sides of the lateral movement of the scooter 14; in order to reduce the friction between the scooter 14 and the side of the first track 15 and the side of the second track 16, the scooter 14 is also connected to a backing wheel 18, which converts sliding friction into rolling friction, which saves effort when the scooter 14 is manually dragged and transported by the transmission mechanism; at the same time, it reduces the collision between the scooter 14 and the first track 15 and the second track 16 during the pushing process, and plays a protective role; the bottom surface of the scooter 14 is connected to a plurality of universal wheels 21, which convert the surface friction between the scooter 14 and the first track 15 into rolling friction, and convert the surface friction between the scooter 14 and the second track 16 into rolling friction, thereby reducing friction loss and saving more effort.
