Description

Technical Field

[0001] The utility model relates to the field of production and manufacturing, in particular to a centering trolley used for an assembly line. Background Art

[0002] When manufacturing products, parts and pallets need to be moved and placed on the conveyor line, and after production is completed, the products and pallets need to be removed from the conveyor line and transferred. However, in actual operation, the carts that place pallets and products often cannot be aligned with the conveyor line, and the products cannot be accurately transported to the conveyor line, resulting in a lot of manual time spent on alignment, reducing production efficiency.

[0003] The patent with patent number: CN107498233A discloses a mobile trolley on an automatic welding production line, including a box body, a second support plate fixedly connected to the top of the box body, a rectangular through hole is provided at one end of the second support plate, and strip sliders are symmetrically provided on both sides of the rectangular through hole, the second support plate is connected to the first support plate through the strip slider, two strip slide grooves are provided at the bottom of the first support plate at positions corresponding to the strip sliders, a placement groove is fixedly connected to the top surface of the first support plate, a baffle is fixedly connected to the bottom surface of the first support plate, the other end of the baffle extends into the rectangular through hole, and two electric telescopic rods are symmetrically connected, a rectangular opening is provided on the side of the box body away from the electric telescopic rod, a third support plate is fixedly connected to the box body, and two positioning protrusions are symmetrically provided on the upper end of the side of the box body with the rectangular opening.

[0004] When in use, the positioning protrusion 12 is pushed by the push handle 1 and placed in the fixing groove set on the automatic welding production line for fixing. The production line is provided with a positioning card block, which extends into the box body 14 and is fixed in the positioning card slot 7, and is fixed again to ensure that the raw materials can be transported to the production line normally.

[0005] However, the following problems still exist during the use of the mobile trolley on the automatic welding production line: 1. The mobile trolley on the automatic welding production line uses positioning bumps and positioning slots when aligning with the production line, which makes alignment difficult and time-consuming; 2. When the production staff aligns, the trolley will also be worn due to excessive thrust, shortening the service life of the trolley. Summary of the invention

[0006] In view of the above-mentioned problems, the utility model aims to provide a centering trolley for an assembly line, thereby overcoming the problem in the prior art that it is difficult to align the moving trolley with the production line and that the trolley is easily worn.

[0007] The main ideas of the technical solution adopted by this utility model are:

[0008] A centering trolley for an assembly line is designed, which includes: a transfer trolley and a centering mechanism. A guide mechanism is provided at the bottom of the transfer trolley, and the centering mechanism is fixed beside one end of a conveyor line. The centering mechanism includes: a baffle and a guide plate connected to the rear side of the baffle, the baffle and the guide plate form an angle of 90 degrees, and the spacing between the two guide plates matches the width of the guide mechanism of the transfer trolley. The width of the top of the transfer trolley is the same as the width of the conveyor line, so that the guide mechanism of the transfer trolley abuts against the angle between the baffle and the guide plate to achieve centering.

[0009] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model to solve its technical problems is:

[0010] A centering trolley for an assembly line, comprising: a transfer trolley with a pallet placed on the upper end, the transfer trolley being used to move the pallet to the top of a conveyor line, and also comprising a centering mechanism and guide mechanisms provided on both sides of the bottom of the transfer trolley;

[0011] The centering mechanism comprises: a baffle and two guide plates connected to the rear side of the baffle, and the distance between the two guide plates matches the distance of the guide mechanism.

[0012] Furthermore, the guide mechanism includes: guide wheels, which are vertically connected to the bottom of the transfer trolley, and the distance between the guide wheels matches the outer spacing of the two guide plates.

[0013] Furthermore, there are two baffles, which are flush and parallel to one end of the conveying line along a preset distance.

[0014] Furthermore, the two guide plates are respectively connected vertically to the two baffles, and the two guide plates are symmetrical along the center line of the conveying line;

[0015] The width of the top of the transfer trolley is the same as the width of the top of the conveyor line.

[0016] Furthermore, the centering mechanism includes: two first buffer plates, one end of the two first buffer plates is respectively connected to the two guide plates, and the other ends of the two first buffer plates are biased to the opposite side of the two guide plates and the included angle is less than 180 degrees.

[0017] Furthermore, anti-collision blocks are provided on both baffles.

[0018] The beneficial effect of the utility model is that compared with the prior art, the improvement of the utility model is that:

[0019] The utility model can easily align the transfer trolley with the conveyor line by arranging the centering mechanism, thereby improving production efficiency, and the centering mechanism has a simple structure and low cost.

[0020] The utility model can not only easily realize the centering of the transfer trolley and the conveyor line by setting the guide mechanism, but also reduce the friction between the transfer trolley and the centering mechanism, thereby extending the service life of the centering mechanism and the transfer trolley.

[0021] The utility model provides an anti-collision block on the guide plate to play a buffering role during centering, avoids direct collision between the transfer trolley and the centering mechanism to cause wear and tear, and prolongs the service life of the centering mechanism.

[0022] The utility model arranges the cam follower as the support member of the tray, which not only has a strong supporting force, but also has a light structure and low cost. BRIEF DESCRIPTION OF THE DRAWINGS
