Description

Technical Field

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

[0002] After the components are assembled on the circuit board, pressure holding is required. The circuit boards are loaded using 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, thereby loading the trays in the material frame one by one. However, the traditional material cart only needs to move to the approximate position before the loading station. For circuit boards, the loading accuracy requirement is high. If the positional accuracy between the material cart and the loading station is not high enough, it will affect the subsequent loading process of the circuit boards. Therefore, it is necessary to manufacture a material cart loading mechanism to solve the above problems. Utility Model Content

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

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

[0017] The present invention will be further described below with reference to the accompanying drawings:

[0018] like Figures 1 to 4 As shown, a material loading mechanism includes a material frame trolley 1, a material frame lifting assembly 2, a guide assembly 3, and a material cart positioning assembly 4. Two sets of guide assemblies 3 are provided, corresponding to the left and right sides of the lifting assembly, respectively. The material frame trolley 1 is located in front of the material frame lifting assembly 2 and between the two sets of guide assemblies 3. A support rod 111 is vertically provided at the rear end of the material frame trolley 1. The material cart positioning assembly 4 includes a first connecting block 41, an elastic telescopic member 42, a positioning cylinder 43, a second connecting block 44, a positioning plate 45, and a sensor 46. The first connecting block 41 is fixedly disposed on one side of the material frame lifting assembly 2. The elastic telescopic member... The rear end of the elastic telescopic member 42 is fixed on the first connecting block 41. The front end of the elastic telescopic member 42 is the elastic telescopic end. The positioning cylinder 43 is fixed on the guide assembly 3. The second connecting block 44 is fixed on the power output end of the positioning cylinder 43. The positioning plate 45 is fixed on the second connecting block 44 and its position is adjustable in the front-back direction. The positioning plate 45 has a positioning boss 451 on the side facing the material frame lifting assembly 2. The front and rear ends of the support rod 111 abut against the rear end face of the positioning boss 451 and the elastic telescopic end of the elastic telescopic member 42, respectively. The sensor 46 is fixed on the second connecting block 44 and its sensing end corresponds to the support rod 111.

[0019] The operator pushes the material frame trolley 1, which is guided by the guide assembly 3 to initially position itself in front of the material frame lifting assembly 2. The support rod 111 on the material frame trolley 1 pushes backward, pressing the elastic extension end of the elastic telescopic component 42. At this time, the sensor 46 detects the support rod 111, and the equipment transmits a signal to the positioning cylinder 43, driving the positioning plate 45 to extend, aligning the positioning boss 451 with the front of the support rod 111. Then, the operator can release the pressure, and the support rod 111, under the action of the elastic telescopic component 42, moves forward to abut against the positioning boss 451, thus completing the precise fixing of the material frame trolley 1. A set of material frame positioning assemblies can be installed on each of the left and right sides of the material frame trolley 1 to further improve positioning accuracy. The advantage of this design is that it can quickly and accurately determine the relative position of the material frame trolley 1 and the material frame lifting assembly 2, improving the positional accuracy when loading circuit boards.

[0020] The material frame trolley 1 includes a trolley base 11, casters 12, vertical push rods 13, handles 14, a first mounting bracket 15, a first material tray guide wheel 16, a second material tray guide wheel 17, and a material frame limiting block 18. The casters 12 are fixed to the four lower corners of the trolley base 11. A support rod 111 is provided at the rear end of the trolley base 11. The lower end of the vertical push rod 13 is fixed to the front side of the trolley base 11. Two sets of vertical push rods 13 are provided, corresponding to the left and right sides of the trolley base 11. The handle 14 is fixed to the upper front end of the vertical push rod 13. On one side, the first mounting bracket 15 is fixed to one side of the vertical push rod 13. Two sets of first mounting brackets 15 are arranged facing each other. The first material tray guide wheel 16 and the second material tray guide wheel 17 can be rotatably installed on the inner side of the first mounting bracket 15. The first material tray guide wheel 16 corresponds to the upper part of the second material tray guide wheel 17. Multiple sets of the first material tray guide wheel 16 and the second material tray guide wheel 17 are arranged in the vertical direction. The material cart base 11 is provided with a lifting cavity 112. The material frame limiting block 18 is fixed above the material cart base 11 and corresponds to the outer periphery of the lifting cavity 112.

[0021] The material frame is first placed in the area enclosed by the material frame limiting block 18 and the first mounting frame 15. Then, the material tray containing the circuit board is inserted between the first material tray guide wheel 16 and the second material tray guide wheel 17 in the same group, so as to quickly place it into the material frame. The operator holds the handle 14 and pushes the material frame trolley 1 to the front of the material frame lifting assembly 2. The lifting cavity 112 on the material trolley base 11 can facilitate the lifting of the material frame by the material frame lifting assembly 2.

[0022] The material frame lifting assembly 2 includes a lifting drive assembly 21, a lifting plate 22, and positioning columns 23. The lifting plate 22 is fixed to the power output end of the lifting drive assembly 21 and corresponds to the lifting cavity 112. Two sets of positioning columns 23 are provided and are fixed above the lifting plate 22.

[0023] The lifting drive assembly 21 drives the lifting carrier plate 22 to rise, thereby driving the material frame to rise gradually so that the subsequent process can load the material tray. The positioning column 23 can cooperate with the positioning hole at the bottom of the material frame to ensure that the position of the material frame is accurate when the material frame is lifted.

[0024] The guide assembly 3 includes a second mounting frame 31, a trolley guide wheel 32, and a frame guide wheel 33. The second mounting frame 31 is fixedly installed on the left and right sides of the frame lifting assembly 2. The trolley guide wheel 32 is rotatably installed on the lower side of the second mounting frame 31. Multiple sets of trolley guide wheels 32 are evenly arranged in the front-back direction and correspond to the trolley base 11. The frame guide wheel 33 is rotatably installed on the upper side of the second mounting frame 31. Multiple sets of frame guide wheels 33 are evenly arranged in the front-back direction and correspond to the upper part of the frame limiting block 18.

[0025] During the process of pushing the material frame trolley 1 to the front of the material frame lifting assembly 2, the material trolley guide wheel 32 guides the two sides of the material trolley base 11, and the material frame guide wheel 33 guides the two sides of the material frame, so that the material frame trolley 1 can be initially positioned quickly.

[0026] 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.
