Description

Technical Field

[0001] This utility model belongs to the technical field of stacked feeding equipment, specifically relating to a blister tray stacking feeding device. Background Technology

[0002] In the field of non-standard automation, especially in inspection lines for small parts, the use of blister packs for loading workpieces is well-known. However, the inventors have discovered at least the following problems in the use of existing blister packs: First, the limited material-holding space of the blister pack limits the number of workpieces that can be placed on each pack, making efficient handling difficult. Furthermore, to improve the accuracy of gripping workpieces within the blister pack, it is necessary to position the blister pack individually, which significantly reduces efficiency. Existing transfer mechanisms often stack full blister packs into packs for transport to improve efficiency; however, due to accuracy issues during stacking, misalignment frequently occurs, causing misalignment when gripping workpieces, reducing gripping accuracy and affecting subsequent processing accuracy. Improvements are urgently needed. Utility Model Content

Detailed Implementation

[0024] The present invention will be further described below through specific embodiments.

[0025] Reference Figures 1 to 7As shown, a blister tray stacking and feeding device includes a frame 1, a conveying mechanism 2 mounted on the frame 1 for conveying blister trays 8, a stacking area 3 mounted on the frame 1 for stacking blister trays 8, two lifting mechanisms 4 mounted on the frame 1 and vertically opposite to the stacking area 3, two clamping and limiting mechanisms 5 mounted on the frame 1 for clamping the blister trays 8 in the stacking area 3, two guide frames 6 mounted on the frame 1, and a limiting plate 7 mounted on the frame 1 opposite to the end of the conveying mechanism 2. The limiting plate 7 can limit the feeding of empty blister trays to prevent them from... When the blister pack is disengaged from the conveying mechanism 2 and is being filled with material, the conveying mechanism 2 is paused. Specifically, the stacking area 3 is formed between the two guide frames 6. Two clamping and limiting mechanisms 5 are respectively set on the two guide frames 6. The limiting plate 7 and the stacking area 3 are respectively set opposite to each other at both ends of the conveying mechanism 2. When the empty blister pack is being filled with material, it is first placed at one end of the conveying mechanism 2. When it is full, the conveying mechanism 2 works to transport it to the stacking area 3. The lifting mechanism 4 works to lift the full blister pack 8 upward and clamp and limit it through the two clamping and limiting mechanisms 5 to complete its stacking in the stacking area 3.

[0026] The conveying mechanism 2 includes two conveying components 21 mounted opposite each other on the frame 1, a synchronous shaft 22 connecting the two conveying components 21, a transmission gear 23 mounted on the synchronous shaft 22, a conveying motor 24 mounted on the frame 1, a rotating gear 25 connected to the output shaft of the conveying motor 24, a transmission belt 26 connecting the transmission gear 23 and the rotating gear 25, and a support base 27 mounted on the frame 1 between the two conveying components 21. The synchronous shaft 22 is mounted on the frame 1 via a mounting base 28, and the support base 27 and mounting base 28 are connected... The inner connection extends outward; specifically, the conveying component 21 includes a conveying frame 211, two conveying gears 212 spaced apart on the conveying frame 211 along the conveying direction, and a conveying toothed belt 213 surrounding the two conveying gears 212. The synchronous shaft 22 is located between the two opposite conveying gears 212 of the two conveying components 21. By defining the structure of the conveying mechanism 2, the two oppositely arranged conveying components 21 cooperate with the support base 27 to realize the transfer of the blister tray 8. There is no need to set the conveyor belt as a whole at the bottom of the blister tray 8, which effectively saves costs.

[0027] The lifting mechanism 4 includes a lifting seat 41, a lifting cylinder 42 disposed on the lifting seat 41 below the stacking area 3, a lifting plate 43 disposed on the upper end of the lifting cylinder 42, two correction plates 44 disposed opposite to each other at both ends of the lifting plate 43, and two pneumatic grippers 45 respectively disposed on the two correction plates 44 to clamp the lower end of the blister tray 8. The pneumatic grippers 45 include two gripper parts 451 that can rotate in opposite directions. The two gripper parts 451 cooperate to clamp the lower edge of the blister tray 8. With the cooperation of other pneumatic grippers, the position of the blister tray 8 can be corrected to ensure its accuracy during the stacking process and prevent misalignment, which will not affect the subsequent gripping accuracy and processing accuracy. Specifically, the pneumatic grippers 45 are commonly used clamping components in the mechanical field, and their specific structure will not be described in detail here.

[0028] The guide frame 6 includes a main frame 61 mounted on the frame 1, guide plates 62 positioned opposite each other on the inner side of the main frame 61, and two right-angled slots 63 spaced apart on the inner side of the guide plates 62. The four right-angled slots 63 form the stacking area 3, and the guide plates 62 form U-shaped clearance slots 621 extending downwards from their tops. Specifically, the main frame 61 includes a support plate 611 mounted on the frame 1, a connecting horizontal plate 612 perpendicular to the upper end of the support plate 611, and two connecting plates 613 spaced apart on the connecting horizontal plate 612 for mounting the opposite guide plates 62. Furthermore, the support plate 611 is detachably connected to the frame 1 via bolt assemblies, and a conveying mechanism is positioned between the two support plates. This application, by defining the structure of the guide frame, uses the four right-angled slots 63 to guide the upwardly lifted blister tray 8. Combined with the pneumatic gripper 45, this further ensures the stability of the blister tray 8 during stacking, preventing misalignment and ensuring subsequent gripping and processing accuracy.

[0029] The clamping and limiting mechanism 5 includes a clamping seat 51 located on the connecting horizontal plate 612 on the outer side of the guide plate 62, a clamping cylinder 52 located on the clamping seat 51 on one side of the stacking area 3, and a clamping block 53 located at the front end of the clamping cylinder 52. The side of the blister tray 8 has an inwardly extending clamping groove 81, and the guide plate 62 has a clearance hole 622 for the clamping block 53 to pass through. The clamping block 53 can pass through the clearance hole 622 and be embedded in the relative clamping groove 81 to clamp the relative blister tray 8. Specifically, the clamping seat 51 has a moving groove 511 for the clamping block 53 to move back and forth. The clamping block 53 includes a connecting section 531 located in the moving groove 511 and connected to the front end of the clamping cylinder 52, and a clamping section 532 located at the front end of the connecting section 531 that can be embedded in the relative clamping groove 81.

[0030] This application defines the structure of the stacking and feeding device and further defines the structure of the lifting mechanism 4. The lifting cylinder 42, in conjunction with the lifting plate 43, lifts the blister tray 8 conveyed to the stacking area 3, moving it upward to the clamping position. Then, the clamping and limiting mechanism 5 clamps the blister tray 8 in the clamping position to complete the stacking of the blister tray 8. Pneumatic grippers 45 are provided on both sides of the lifting plate 43, which can clamp the lower edge of the blister tray 8 during the lifting process, and perform position correction on the blister tray 8 conveyed to the stacking area 3 to ensure its accuracy during the stacking process, prevent misalignment, and not affect the subsequent gripping and processing accuracy.
