Description

Technical Field

[0001] This utility model relates to the field of circuit board processing equipment, and in particular to a material tray feeding mechanism. Background Technology

[0002] After the components are assembled on the circuit board, pressure holding is required. The circuit boards are loaded via a material cart. Multiple sets of circuit boards are placed in the same tray, and multiple trays are neatly arranged in a material frame. The material cart pushes the material frame to the loading station, where the trays in the material frame are loaded one by one. However, vibrations occur during the lifting of the material frame or during the subsequent operation of the equipment, which can cause the trays to shift in position within the material frame, making it difficult to load the trays accurately. Therefore, it is necessary to develop a tray loading mechanism to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to provide a material tray feeding mechanism to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A material tray feeding mechanism includes a material frame body, a material tray body, a material tray removal assembly, a material tray locking assembly, and an unlocking assembly. The material tray body is slidably installed in the material frame body in a front-to-back direction. Multiple sets of material tray bodies are arranged vertically in the material frame body. A locking groove is provided at the lower edge of the material tray body. The material tray removal assembly is fixedly installed on the rear side of the material frame body. The material tray locking assembly includes a drive arm, a first connecting post, a second connecting post, a third connecting post, a compression spring, a locking roller, a drive handle, and a limit screw. The middle part of the drive unit is hinged to the outer side wall of the material frame body. The first connecting post is fixed to the drive arm. At the front end of the boom, the second connecting column is fixed to the outer side wall of the material frame body and corresponds to the top of the first connecting column. One end of the third connecting column is fixed to the front end of the drive arm and the other end passes through the material frame body. The two ends of the compression spring are fixed to the first connecting column and the second connecting column respectively. The locking roller is rotatably installed on the inner end of the third connecting column and corresponds to the locking groove. The drive handle is rotatably installed on the rear end of the drive arm. The limit screw is threaded to the side wall of the material frame body and corresponds to the lower rear end of the drive arm. The unlocking component is fixed on one side of the material tray removal component and is used to lift the drive handle.

[0006] Further description of this utility model: The tray removal assembly includes a Y-axis drive assembly, a movable base plate, a Z-axis cylinder, a lifting connecting plate, a pushing plate, and a Y-axis slide rail. The Y-axis drive assembly is fixedly installed on the rear side of the material frame body. The movable base plate is fixed to the power output end of the Y-axis drive assembly. The Z-axis cylinder is fixed above the movable base plate. The lifting connecting plate is fixed to the power output end of the Z-axis cylinder. The pushing plate is fixed below the lifting connecting plate. Two sets of pushing plates are arranged along the front-rear direction. The lower ends of the two sets of pushing plates are provided with bevels on opposite sides. Two sets of Y-axis slide rails are arranged and fixedly installed on the left and right sides of the Y-axis drive assembly, respectively. The unlocking assembly is fixed on one side of the Y-axis slide rail. A pushing boss is provided above the rear end of the tray body. During the tray removal process, both ends of the tray body are slidably connected to the two sets of Y-axis slide rails, respectively. The pushing boss corresponds to the space between the two sets of pushing plates.

[0007] Further description of the present invention: The unlocking component includes an unlocking cylinder and an unlocking drive block. The unlocking cylinder is fixed on the outside of the Y-axis slide rail and the power output end faces forward. The unlocking drive block is fixed on the power output end of the unlocking cylinder, and a drive ramp is provided on the upper front side of the unlocking drive block.

[0008] The beneficial effects of this utility model are as follows: When feeding the tray, the tray frame body is moved to the front of the tray removal assembly by a trolley, and the lifting device gradually lifts the tray body so that the tray removal assembly can remove the tray body layer by layer. Before the tray is removed, the compression spring pulls the front end of the drive arm upward through the first connecting column, and the lower rear end of the drive arm abuts against the limit screw. At this time, the front end of the drive arm is at its maximum rising height, and the locking roller corresponds to the locking groove of the tray body, so that the tray body will not shift due to equipment vibration. When the tray needs to be removed, the unlocking assembly raises the drive handle, thereby lowering the front end of the drive arm, and finally the locking roller disengages from the locking groove, so that the tray body can be moved outward by the tray removal assembly. The advantage of this design is that it can ensure that the tray body will not be affected by equipment vibration during the feeding process, thus improving the feeding accuracy.

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

[0017] like Figures 1 to 5 As shown, a material tray feeding mechanism includes a material frame body 1, a material tray body 2, a material tray removal assembly 3, a material tray locking assembly 4, and an unlocking assembly 5. The material tray body 2 is slidably installed inside the material frame body 1 in the front-to-back direction. Multiple sets of material tray bodies 2 are arranged vertically inside the material frame body 1. A locking groove 21 is provided at the lower edge of the material tray body 2. The material tray removal assembly 3 is fixedly installed on the rear side of the material frame body 1. The material tray locking assembly 4 includes a drive arm 41, a first connecting post 42, a second connecting post 43, a third connecting post 44, a compression spring 45, a locking roller 46, a drive handle 47, and a limit screw 48. The middle part of the drive unit is hinged to the outer side wall of the material frame body 1. The first connecting post 42 is fixed to the drive arm 41. At the front end of the boom 41, the second connecting post 43 is fixed to the outer side of the side wall of the material frame body 1 and corresponds to the top of the first connecting post 42. One end of the third connecting post 44 is fixed to the front end of the drive arm 41 and the other end passes through the material frame body 1. The two ends of the compression spring 45 are respectively fixed to the first connecting post 42 and the second connecting post 43. The locking roller 46 is rotatably installed on the inner end of the third connecting post 44 and corresponds to the locking groove 21. The drive handle 47 is rotatably installed on the rear end of the drive arm 41. The limit screw 48 is threaded to the side wall of the material frame body 1 and corresponds to the lower rear end of the drive arm 41. The unlocking component 5 is fixed on one side of the material tray removal component 3 and is used to lift the drive handle 47.

[0018] When loading the tray, the tray frame 1 is moved to the front of the tray removal assembly 3 by a trolley, and the lifting device gradually lifts the tray frame 1 so that the tray removal assembly 3 can remove the tray body 2 layer by layer. Before the tray is removed, the compression spring 45 pulls the front end of the drive arm 41 upward through the first connecting column 42, and the lower rear end of the drive arm 41 abuts against the limit screw 48. At this time, the front end of the drive arm 41 is at its maximum rising height, and the locking roller 46 corresponds to the locking groove 21 of the tray body 2, so that the tray body 2 will not be displaced due to equipment vibration. When the tray needs to be removed, the unlocking assembly 5 lifts the drive handle 47, so that the front end of the drive arm 41 descends, and finally the locking roller 46 disengages from the locking groove 21, so that the tray body 2 can be moved outward by the tray removal assembly 3. The advantage of this design is that it can ensure that the tray body 2 will not be affected by equipment vibration during the loading process, thus improving the loading accuracy.

[0019] The tray removal assembly 3 includes a Y-axis drive assembly 31, a movable base plate 32, a Z-axis cylinder 33, a lifting connecting plate 34, a push plate 35, and a Y-axis slide rail 36. The Y-axis drive assembly 31 is fixedly installed on the rear side of the material frame body 1. The movable base plate 32 is fixed to the power output end of the Y-axis drive assembly 31. The Z-axis cylinder 33 is fixed above the movable base plate 32. The lifting connecting plate 34 is fixed to the power output end of the Z-axis cylinder 33. The push plate 35 is fixed below the lifting connecting plate 34. Two sets of push plates 35 are arranged along the front-rear direction. The lower ends of the two sets of push plates 35 are provided with an angle on the opposite side. Two sets of Y-axis slide rails 36 are arranged and fixedly installed on the left and right sides of the Y-axis drive assembly 31, respectively. The unlocking assembly 5 is fixed on one side of the Y-axis slide rail 36. A push boss 22 is provided above the rear end of the tray body 2. During the tray removal process, both ends of the tray body 2 are slidably connected to the two sets of Y-axis slide rails 36, and the push boss corresponds to the two sets of push plates 35.

[0020] After the unlocking component 5 unlocks the tray locking component 4, the Z-axis cylinder 33 drives the lifting connecting plate 34 to rise, and the Y-axis drive component 31 drives the push plate 35 to move forward and correspond to the push boss 22. Then, the Z-axis cylinder 33 drives the lifting connecting plate 34 to fall, so that the push boss 22 is inserted into the front and rear push plates 35. Then, under the drive of the Y-axis drive component 31, the tray body 2 is pulled and slides backward along the Y-axis slide rail 36, and the tray body 2 is transported to the next process.

[0021] The unlocking component 5 includes an unlocking cylinder 51 and an unlocking drive block 52. The unlocking cylinder 51 is fixed on the outside of the Y-axis slide rail 36 with its power output end facing forward. The unlocking drive block 52 is fixed on the power output end of the unlocking cylinder 51. A drive ramp 521 is provided on the upper front side of the unlocking drive block 52.

[0022] When it is necessary to unlock the tray locking component 4, the unlocking cylinder 51 drives the unlocking drive block 52 to move forward, so that the drive inclined surface 521 abuts against the side of the drive handle 47 and lifts it up. As the drive handle 47 is continuously lifted, the unlocking is finally completed.

[0023] The above does not limit the technical scope of this utility model. Any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall still fall within the scope of the technical solution of this utility model.
