Description

Technical Field

[0001] This utility model relates to the field of equidistant conveying equipment, specifically an equidistant pulling mechanism. Background Technology

[0002] In automated product processing equipment, products need to be transferred between different processes. The processing time and quantity vary between these processes; for example, a receiving mechanism receives products one by one, while a processing station needs to process multiple products at once. Therefore, an equidistant pulling mechanism is needed to separate the products that are received one by one and stacked, facilitating transfer by the transfer mechanism. Existing equidistant pulling mechanisms mostly use scissor-type mechanisms. Scissor-type mechanisms have complex structures and require space on both sides when retracting.

[0003] For example, Chinese patent CN217971472U discloses an equidistant pulling mechanism, including a scissor-type pulling module and a positioning and pushing mechanism. The scissor-type pulling module is moved by a horizontal drive, and the positioning and pushing mechanism is located at the outlet of the conveyor track. The scissor-type pulling module picks up multiple products from the positioning and pushing mechanism and pulls the multiple products apart at equal intervals. This patent uses a scissor-type pulling module to achieve the equidistant pulling function. However, the scissor-type pulling module is prone to wear and failure after long-term use, and the scissor structure occupies a large space when retracted, making it inconvenient to use.

[0004] Therefore, it is necessary to provide an equidistant pulling mechanism. Utility Model Content

[0005] The present invention provides an equidistant opening mechanism, which effectively solves the problems of space occupation and inconvenience of use when the existing equidistant opening mechanism is retracted.

[0006] The technical solution adopted in this utility model is:

[0007] An equidistant opening mechanism includes a frame, a first linear guide rail arranged along the X direction on the frame, a first suction assembly fixedly arranged on the frame and located at the right end of the first linear guide rail, several second suction assemblies slidably arranged on the first linear guide rail, several sliding limit rods, a first cylinder extending along the X direction on the frame for driving the leftmost second suction assembly to slide along the first linear guide rail, and two adjacent second suction assemblies, wherein the first suction assembly and the adjacent second suction assembly are slidably connected by sliding limit rods.

[0008] Furthermore, the first suction assembly includes a first base fixedly connected to the frame and a first suction cup disposed on the first base; the second suction assembly includes a second base slidably connected to the first linear guide rail and a second suction cup disposed on the second base; the sliding limit rod is slidably connected to two adjacent second bases, and the first base is slidably connected to adjacent second bases.

[0009] Furthermore, the sliding limiting rod includes a rod body and limiting discs disposed at both ends of the rod body. The first base and the second base are both provided with round holes that are slidably connected to the rod body and a clearance area for the limiting discs to avoid being positioned. The limiting discs are located within the clearance area.

[0010] Furthermore, it also includes a left-right centering component, which includes a first fixed seat located at the right end of the first suction component, a second cylinder located on the first fixed seat along the X direction with its output end facing the left, a right push block fixedly located at the output end of the second cylinder, a second mounting seat located on the left side of the leftmost second suction component, a third cylinder located on the second mounting seat along the X direction with its output end facing the right, and a left push block located at the output end of the third cylinder.

[0011] Furthermore, the frame is also equipped with a front and rear alignment assembly, which includes a second linear guide rail arranged on the frame along the Y-axis, a front baffle and a rear baffle slidably arranged on the second linear guide rail, a fourth cylinder arranged on the frame for driving the front baffle to slide along the second linear guide rail, and a fifth cylinder for driving the rear baffle to slide along the second linear guide rail.

[0012] Furthermore, both the front and rear baffles are provided with perforated holes.

[0013] Furthermore, the number of the second suction components is at least three.

[0014] The beneficial effects of this utility model are: it enables the separation or merging of products on the first and second suction components, facilitating transfer by subsequent mechanisms. When transitioning from the extended to the retracted state, the sliding limit rods do not occupy external space, simplifying installation and improving ease of use. Attached Figure Description

Detailed Implementation

[0020] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0021] like Figure 1 and Figure 2 As shown, the embodiment of this application provides an equidistant pulling mechanism, including a frame 1, a first linear guide rail 2 arranged along the X direction on the frame 1, a first suction component 3 fixedly arranged on the frame 1 and located at the right end of the first linear guide rail 2, a plurality of second suction components 4 slidably arranged on the first linear guide rail 2, a plurality of sliding limit rods 5, a first cylinder 8 extending along the X direction on the frame 1 for driving the leftmost second suction component 4 to slide along the first linear guide rail 2, and adjacent second suction components 4, the first suction component 3 and the adjacent second suction component 4 are all slidably connected by sliding limit rods 5.

[0022] In actual use, when it is necessary to separate the first suction assembly 3 and the second suction assembly 4, the first cylinder 8 drives the leftmost second suction assembly 4 to move to the left along the first linear guide rail 2. This causes the leftmost second suction assembly 4 to move synchronously with the sliding limit rod 5, which is slidably connected to it, thus causing the adjacent second suction assembly 4 to move synchronously. This continues until the stroke of the first cylinder 8 ends. At this point, the rightmost second suction assembly 4 separates from the first suction assembly 3, making the distance between the first suction assembly 3 and the adjacent second suction assembly 4, as well as between two adjacent second suction assemblies 4, equal. When it is necessary to close the first suction assembly 3 and the second suction assembly 4, the output end of the first cylinder 8 retracts, causing the leftmost second suction assembly 4 to move to the right and then abut against the adjacent second suction assembly 4, pushing the adjacent second suction assembly 4 to move to the right. This continues until the rightmost second suction assembly 4 abuts against the first suction assembly 3.

[0023] The above design enables the separation or merging of products on the first suction assembly 3 and the second suction assembly 4, facilitating transfer by subsequent mechanisms. When transitioning from the extended to the retracted state, each sliding limit rod 5 does not occupy external space, simplifying installation and improving ease of use.

[0024] Specifically: such as Figure 2 As shown, the first suction assembly 3 includes a first base 31 fixedly connected to the frame 1 and a first suction cup 32 disposed on the first base 31. The second suction assembly 4 includes a second base 41 slidably connected to the first linear guide rail 2 and a second suction cup 42 disposed on the second base 41. The sliding limit rod 5 is slidably connected to two adjacent second bases 41, and the first base 31 is slidably connected to adjacent second bases 41.

[0025] In actual use, several products are respectively attracted and fixed by suction cup 32 and suction cup 42. Base 41 slides along linear guide rail 2, while base 31 remains fixed.

[0026] In the above design, the structural design and specific implementation of the first suction component 3 and the second suction component 4 can effectively achieve the adsorption of the product. The second base 41 can drive the second suction cup 42 to slide along the second linear guide rail 71, ensuring the stability of the product in the second suction cup 42.

[0027] Specifically: such as Figure 3 As shown, the sliding limiting rod 5 includes a rod body 51 and limiting discs 52 disposed at both ends of the rod body 51. Both the first base 31 and the second base 41 are provided with circular holes that slide through the rod body 51 and clearance areas for the limiting discs 52 to avoid obstruction. The limiting discs 52 are located within the clearance areas. The first base 31 and the second base 41 include a bottom wall and side walls disposed on the bottom wall, with the circular holes disposed on the side walls. The second base 41 includes a left side wall and a right side wall, while the first base 31 only includes a left side wall.

[0028] In actual use, taking two adjacent suction components 4 as an example, when the left suction component 4 moves to the left along the linear guide rail 2, the right side wall of the left suction component 4 limits the left limiting plate 52, causing the sliding limiting rod 5 to move synchronously to the left. When the right limiting plate 52 contacts the left side wall of the right suction component 4, it causes the right suction component 4 to move synchronously, achieving separation. When closing, during the sliding to the right of the left suction component 4, before closing, the left limiting plate 52 slides to the left relative to the right side wall of the left suction component 4 until the left suction component 4 and the right suction component 4 close together.

[0029] In the above design, the structural design and specific implementation of the sliding limit rod 5 facilitate the sliding connection between the first suction component 3 and the second suction component 4, and drive the second suction component 4 to move.

[0030] Specifically: such as Figure 1 and Figure 2 As shown, it also includes a left-right centering component, which includes a first fixed seat 61 located at the right end of the first suction component 3, a second cylinder 62 located on the first fixed seat 61 along the X direction with its output end facing the left, a right push block 63 fixedly located at the output end of the second cylinder 62, a second mounting seat 64 located on the left side of the leftmost second suction component 4, a third cylinder 65 located on the second mounting seat 64 along the X direction with its output end facing the right, and a left push block 66 located at the output end of the third cylinder 65.

[0031] In actual use, after the product is attracted by the first suction component 3 and the second suction component 4, the first suction component 3 and the second suction component 4 close together. The second cylinder 62 and the third cylinder 65 drive the right push block 63 and the left push block 66 to move towards each other, so that the right push block 63 and the left push block 66 form a limit on all products in the left and right directions.

[0032] In the above design, the structural design and specific implementation of the left and right centering components can provide limiting protection for the closed product in the left and right directions.

[0033] Specifically: such as Figure 1 and Figure 4 As shown, the frame 1 is also provided with a front and rear alignment assembly 7. The front and rear alignment assembly 7 includes a second linear guide rail 71 arranged along the Y-axis direction on the frame 1, a front baffle 72 and a rear baffle 73 slidably arranged on the second linear guide rail 71, a fourth cylinder 74 arranged on the frame 1 for driving the front baffle 72 to slide along the second linear guide rail 71, and a fifth cylinder 75 for driving the rear baffle 73 to slide along the second linear guide rail 71.

[0034] In actual use, when the product needs to be limited in the front and rear directions, the front baffle 72 is driven to move to the rear by the fourth cylinder 74, and the rear baffle 73 is driven to move to the front by the fifth cylinder 75, thereby limiting the product in the front and rear directions.

[0035] In the above design, the structural design and specific implementation of the front and rear centering component 7 can effectively limit the product in the front and rear directions.

[0036] Specifically, both the front baffle 72 and the rear baffle 73 are provided with perforated holes.

[0037] In the above design, the weight of the front baffle 72 and the rear baffle 73 can be reduced by setting hollow holes on the front baffle 72 and the rear baffle 73.

[0038] Specifically: such as Figure 1 and Figure 2 As shown, the number of the second suction assembly 4 is at least three.

[0039] In the above design, the second suction component 4 is set to three or more, which can work with the first suction component 3 to separate or close at least four products.

[0040] In further detail, it should be understood that the above description is only a specific embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
