Description

Technical Field

[0001] This utility model relates to a lifting device, and more particularly to a linkage-type side lifting device. Background Technology

[0002] The assembly and testing of FPC flexible circuit boards are carried out using automated equipment. During testing, the FPC flexible circuit boards need to be lifted by a lifting mechanism. Existing lifting mechanisms, such as... Figure 5 As shown, the mechanism consists of a fixed plate, a movable plate, linear bearings, and a lifting cylinder. The lifting cylinder is vertically positioned below the movable plate, driving the movable plate to rise and fall. This structure does not make high space utilization. In addition, some products are narrow in width and long in length. General lifting mechanisms cannot be compatible with narrow products and cannot meet the requirement of simultaneous lifting and positioning on both sides. In other words, when the movable plate is long, it is easy to cause differences in the height of movement at both ends of the movable plate. Utility Model Content

[0003] To address the issues of excessive space occupation and inconsistent lifting heights at both ends in the aforementioned lifting mechanisms, this utility model provides a linkage-type side lifting device, the specific technical solution of which is as follows:

[0004] A linkage-type side lifting device includes: a lifting base plate mounted on a frame; a lifting plate slidably mounted on the lifting base plate; a movable plate mounted on the lifting plate; two cams rotatably mounted on the lifting base plate, with one end of each cam movably abutting the bottom of the lifting plate; a connecting rod rotatably mounted on the cam; and a lifting cylinder rotatably mounted on the frame and rotatably connected to one end of the connecting rod, used to drive the cams to rotate via the connecting rod, the cams being used to push the lifting plate up and down.

[0005] Preferably, it further includes: a lifting roller, which is rotatably mounted on the cam and movably abuts against the lifting plate, for pushing the lifting plate to rise and fall.

[0006] Furthermore, it also includes: a drive plate, disposed on the lifting plate and in a waist-shaped drive groove, wherein the lifting roller is movably inserted into the drive groove.

[0007] Preferably, it further includes: linear guide rails, which are disposed on the lifting plate and two are symmetrically arranged; and sliders, which are slidably disposed on the linear guide rails and connected to the lifting base plate.

[0008] Preferably, the lifting plate has lifting grooves at both ends, and the cam is located in the lifting groove.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] The present invention provides a linkage-type side lifting device in which the lifting cylinder is set on the side and the moving plate is lifted from both ends simultaneously by the cam and the connecting rod. It can effectively meet the side lifting and positioning of products with small width and long size, and improve the space utilization rate. Attached Figure Description

[0016] The present invention will now be further described with reference to the accompanying drawings.

[0017] like Figures 1 to 4 As shown, a linkage-type side lifting device includes a lifting base plate 1, a linear guide rail pair, a lifting plate 33, a moving plate 35, lifting rollers 42, a connecting rod 49, a lifting cylinder 47, and a drive plate 41. The lifting base plate 1 is mounted on a frame. The linear guide rails 31 are fixed on the lifting plate 33, and two are symmetrically arranged. The linear guide rails 31 are vertically arranged. The slider 32 is slidably mounted on the linear guide rails 31 and connected to the lifting base plate 1. The lifting plate 33 rises and falls vertically. The moving plate 35 is fixed to the top of the lifting plate 33. The cam 43 is a right-angled triangle. The right angle of the cam 43 is rotatably mounted on the lifting base plate 1 through a first rotating shaft 44. One corner of the cam 43 is rotatably connected to the connecting rod 49 through a second rotating shaft 45. The other corner of the cam 43 movably abuts against the bottom of the lifting plate 33. Two cams 43 are symmetrically arranged and are located at both ends of the bottom of the lifting base plate 1 and at both ends of the lifting plate 33. The tail end of the lifting cylinder 47 is rotatably mounted on the frame. The lifting cylinder 47 is horizontally positioned, and the end of the piston rod of the lifting cylinder 47 is connected to one end of the connecting rod 49 through a key bearing 46.

[0018] When the piston rod of the lifting cylinder 47 extends, the connecting rod 49 drives the two cams 43 to flip upward, and the cams 43 lift the lifting plate 33, which in turn drives the moving plate 35 to rise. When the piston rod of the lifting cylinder 47 retracts, the cams 43 return to their original positions, and the lifting plate 33 and the moving plate 35 descend to their original positions under the action of gravity.

[0019] Because the lifting cylinder 47 is located on the side, the height of the lifting device can be greatly reduced, the height of the conveying device can be lowered, and the space utilization rate can be improved.

[0020] The two cams 43 simultaneously lift the lifting plate 33 from both ends, which can effectively ensure that the lifting height of both ends of the lifting plate 33 is consistent, improve the accuracy of lifting and positioning, and reduce the error caused by the deformation of the long moving plate 35.

[0021] The cam 43 and the lifting plate 33 can be driven by the lifting roller 42. The lifting roller 42 transforms the sliding friction between the cam 43 and the lifting plate 33 into rolling friction, making the movement smoother and more reliable. The lifting roller 42 and the second rotating shaft 45 are located on both sides of the first rotating shaft 44, forming a triangle.

[0022] To improve the reliability of lifting, a drive plate 41 is also included. The drive plate 41 is fixed to the bottom of the lifting plate 33. The drive plate 41 is provided with a drive groove 411, which is an oblong groove and is arranged in the horizontal direction. The lifting roller 42 is movably inserted into the drive groove 411. The lifting roller 42 and the drive groove 411 can drive the lifting plate 33 and the moving plate 35 to reset, preventing the lifting plate 33 and the moving plate 35 from failing to descend on their own and ensuring reliable lifting.

[0023] The lifting plate 33 has symmetrical lifting grooves 331 at both ends. The cam 43 and the lifting roller 42 are located in the lifting grooves 331. The lifting grooves 331 can further compress the height of the lifting device, making the structure more compact.

[0024] The linkage-type side lifting device has a small overall height, which can effectively accommodate products with small width and long dimensions in a relatively limited space.

[0025] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without inventive effort, and these embodiments will all fall within the protection scope of the claims of this utility model.
