Description

Technical Field

[0001] The invention relates to the technical field of automated conveying, in particular to a double transfer platform for loading and unloading products. Background Art

[0002] A transfer platform is a mechanical device used to move heavy objects or equipment in an industrial environment. The platform structure is commonly a wheeled, tracked, suspended or other automated mobile device, usually equipped with electric, hydraulic, pneumatic systems and control systems to achieve precise positioning and operation. The transfer platform is usually integrated into processing equipment or testing equipment to achieve accurate loading of equipment during the production process, as well as positioning of products during the operation of processing equipment or testing equipment, thereby improving the degree of automation and production efficiency.

[0003] At present, the transfer platform is usually reciprocating. The transfer platform carries a product to the operating position of the equipment (i.e., the loading position). After completing the operation, the transfer platform carries the product to the unloading position, removes the product, replaces a product, and then repeats the above process to achieve automatic loading and unloading of products, but the production efficiency is low.

[0023] Among them, the driving shaft moves under the action of the spring restoring force, and drives the first elastic limit member and the second elastic limit member to move toward the product through the first connecting rod structure and the second connecting rod structure respectively, so that the fixed limit structure, the first elastic limit member and the second elastic limit member are all in contact with the outer peripheral surface of the product, limiting the position of the product relative to the slide.

[0024] The first connecting rod structure includes a first arm and a second arm, one end of the first arm is hinged to the end of the driving shaft, the other end of the first arm is hinged to one end of the second arm, the other end of the second arm is hinged to the base plate, and the first elastic limiter is fixedly mounted on the first arm;

[0030] The second contact portion is a plane, and the plane is parallel to the axis of the driving shaft.

[0031] It also includes an automatic push rod mechanism fixedly arranged between the two first linear drive mechanisms, and the automatic push rod mechanism and the third linear drive mechanism correspond to two ends of the first linear drive mechanism respectively;

[0032] The automatic push rod mechanism comprises a first push rod and a second push rod, wherein the first push rod corresponds to the tail end of a driving shaft of one positioning seat, and the second push rod corresponds to the tail end of a driving shaft of another positioning seat, and the two driving shafts are parallel to each other and face oppositely from head to tail;

[0040] The beneficial effects of the present invention are as follows:

[0041] The present invention has a compact and reasonable structure and is easy to operate. With the working position of the processing equipment or the testing equipment as the center, the first linear drive mechanism and the second linear drive mechanism are symmetrically arranged, so that the two sets of transfer mechanisms share a vertical positioning mechanism, which can meet the requirement that when one product is at the working position of the equipment, the other product is transported to the unloading position at the other end of the first linear drive mechanism, and the material can be picked up and the new product can be positioned and placed, making the overall structure of the transfer platform compact, ensuring accurate loading while improving production efficiency.

[0042] The present invention also includes the following advantages:

[0043] (1) The elastic limiting structure elastically connected to the substrate and the fixed limiting structure fixedly installed on the substrate are used to elastically constrain and position the product from the outer periphery of the product, thereby ensuring the fit between the positioning structure and the product, thereby ensuring the positioning accuracy of the product.

[0044] (2) A driving shaft is slidably installed on the base plate. The driving shaft is elastically connected to the base plate through a spring. The axial displacement of the driving shaft is converted into displacements of the first elastic limiter and the second elastic limiter in two different directions through the first connecting rod structure and the second connecting rod structure. The restoring force of the spring is used as the driving force to drive the first elastic limiter and the second elastic limiter to move. Under the action of the elastic force of the spring, the first elastic limiter, the second elastic limiter and the fixed limiter structure are brought into contact with the outer peripheral surface of the product, thereby realizing accurate and flexible positioning of the product.

[0045] (3) For products with a rectangular ring structure on the outer circumference, a plane parallel to the axis of the drive shaft is set on the second elastic limit member to align the product from one side of the product, and the first elastic limit member pushes the product from the other side of the product. The first elastic limit member and the second elastic limit member cooperate to achieve two-way synchronous adjustment, thereby improving the adjustment efficiency. At the same time, the elastic limit structure as a whole is semi-circular and surrounds the outer circumference of the product. The drive shaft is parallel to one side of the product, thereby reducing the overall structural size of the positioning seat and miniaturizing the double transfer platform.

[0046] (4) An automatic push rod mechanism is provided between the two first linear drive mechanisms to realize automatic pushing of the driving shaft, so that the positioning seat releases the limit on the product, and the double transfer platform can be connected to the automatic conveyor line to realize automatic picking and placing of the product. At the same time, the tail ends of the driving shafts of the two positioning seats are both facing the first linear drive mechanism, so that the structure of the double transfer platform is compact and the space utilization rate is improved.

[0047] (5) By converting the linear displacement of the cylinder into the rotational displacement of the synchronous belt, the linear displacement of the cylinder is amplified and then transmitted to the movable plate. Under the condition of limited space and without changing the stroke of the second linear drive mechanism, the axial length of the cylinder is reduced, the overall size of the second linear drive mechanism is reduced, the cost is reduced, and the space is saved.

[0073] The specific implementation of the present invention will be described below in conjunction with the accompanying drawings.

[0074] Embodiment 1:

[0075] like Figure 1-Figure 5 As shown, the double transfer platform for loading and unloading products in this embodiment includes a pair of first linear drive mechanisms 5, a pair of second linear drive mechanisms 4, a slide 3, a third linear drive mechanism 6 and a positioning seat 1.

[0076] A pair of first linear drive mechanisms 5 are arranged parallel to each other and spaced apart on the platform body 7;

[0077] A pair of second linear drive mechanisms 4 are respectively fixedly mounted on a moving part of a first linear drive mechanism 5, and the moving direction of the moving part of the first linear drive mechanism 5 is perpendicular to the moving direction of the moving part of the second linear drive mechanism 4;

[0078] The slide 3 is slidably connected to the moving part of the second linear drive mechanism 4, the sliding direction of the slide 3 is vertical, and the moving directions of the moving parts of the first linear drive mechanism 5 and the second linear drive mechanism 4 are both perpendicular to the sliding direction of the slide 3;

[0079] The third linear drive mechanism 6 is fixedly mounted on the platform body 7 between the two first linear drive mechanisms 5 and corresponds to one end of the first linear drive mechanism 5;

[0080] The positioning seat 1 is fixedly mounted on the slide 3 and is used for positioning and placing the product 2;

[0081] When the slide 3 is driven by the first linear drive mechanism 5 and the second linear drive mechanism 4 to move to the top of the third linear drive mechanism 6, the moving part of the third linear drive mechanism 6 lifts the slide 3 from the bottom of the slide 3 so that the product 2 is at the loading height.

[0082] like Figure 1 As shown, based on the spatial coordinate system, the moving part of the first linear drive mechanism 5 moves in the X-axis direction, the moving part of the second linear drive mechanism 4 moves in the Y-axis direction, and the moving parts of the slide 3 and the third linear drive mechanism 6 move in the Z-axis direction.

[0083] The structure of the linear drive mechanism can be realized in various ways, such as electric cylinder, pneumatic cylinder and other linear drive drives the sliding guide slider to move the structure. The platform body 7 can be a structural member fixed relative to the processing equipment or testing equipment, preferably a whole plate.

[0084] The third linear drive mechanism 6 corresponds to the operating position of the processing equipment or the testing equipment, that is, the loading position, and is located between one ends of the two first linear drive mechanisms 5. The other ends of the two first linear drive mechanisms 5 are the unloading positions, and there are two unloading positions.

[0085] With the working position of the processing equipment or the testing equipment as the center, the first linear drive mechanism 5 and the second linear drive mechanism 4 are symmetrically arranged, so that the two sets of transfer mechanisms share a vertical positioning mechanism, which can meet the requirement that when one product 2 is at the working position of the equipment, another product 2 is transported to the unloading position at the other end of the first linear drive mechanism 5, and the material can be picked up and the new product 2 can be positioned and placed, making the overall structure of the transfer platform compact, ensuring accurate loading while improving production efficiency.

[0086] Embodiment 2:

[0087] The positioning seat 1 needs to be designed accordingly for products with different structural forms. Based on the first embodiment, this embodiment further improves the structural form of the positioning seat 1 to improve the positioning effect of the product 2.

[0088] like Figure 6 , Figure 7 As shown, the structure of the positioning seat 1 includes a base plate 10, and the base plate 10 is used to support the product 2 from below the product 2. A fixed limiting structure and an elastic limiting structure are provided on the base plate 10;

[0089] The fixed limiting structure is fixedly installed on the substrate 10, and the elastic limiting structure is elastically connected to the substrate 10, which is used to change the relative position between the fixed limiting structure and the elastic limiting structure so that the fixed limiting structure and the elastic limiting structure adapt to the outer peripheral surface of the product 2, thereby positioning the product 2 on the substrate 10.

[0090] By means of an elastic limiting structure elastically connected to the substrate 10 and a fixed limiting structure fixedly mounted on the substrate 10, the product 2 is elastically constrained and positioned from the outer periphery of the product 2, thereby ensuring the fit between the positioning structure and the product 2 and further ensuring the positioning accuracy of the product 2.

[0091] Further, if Figure 6 , Figure 7 As shown, the elastic limiting structure includes: a driving shaft 15 , a first connecting rod structure 18 , a first elastic limiting member 13 , a second connecting rod structure 17 , a second elastic limiting member 14 and a spring 16 .

[0092] The driving shaft 15 is slidably mounted on the base plate 10;

[0093] One end of the first connecting rod structure 18 is hinged to the base plate 10, and the other end of the first connecting rod structure 18 is hinged to the head end of the driving shaft 15;

[0094] The first elastic limiting member 13 is fixedly installed at the middle part of the first connecting rod structure 18;

[0095] The second connecting rod structure 17 is hingedly mounted on the base plate 10, and the second connecting rod structure 17 is transmission-connected to the middle of the driving shaft 15;

[0096] The second elastic limiting member 14 is fixedly mounted on the moving rod 172 of the second connecting rod structure 17;

[0097] The spring 16 is disposed at the rear end of the driving shaft 15 and is in a compressed state, and is used to elastically connect the driving shaft 15 to the base plate 10;

[0098] Among them, the driving shaft 15 moves under the action of the restoring force of the spring 16, and drives the first elastic limit member 13 and the second elastic limit member 14 to move toward the product 2 through the first connecting rod structure 18 and the second connecting rod structure 17, so that the fixed limit structure, the first elastic limit member 13 and the second elastic limit member 14 are all in contact with the outer peripheral surface of the product 2, limiting the position of the product 2 relative to the slide 3.

[0099] Specifically, the driving shaft 15 is slidably mounted on the base plate 10 through a pair of linear bearings, the second connecting rod structure 17 is located between the two linear bearings, a first limiting structure 151 is provided on one side of the head end of the driving shaft 15, a limiting block 152 is provided at the tail end of the driving shaft 15, and a spring 16 is sleeved on the driving shaft 15 between the linear bearing adjacent to the limiting block 152 and the limiting block 152. No external force is applied to the tail end of the driving shaft 15, and under the limiting action of the first limiting structure 151, the lower spring 16 is in a compressed state.

[0100] The drive shaft 15 is elastically connected to the base plate 10 through the spring 16, and the elastic force is transmitted to the first elastic limiter 13 and the second elastic limiter 14 through the first connecting rod structure 18 and the second connecting rod structure 17, so as to push the product 2 to move and ensure that the product 2 fits well with the limit structure to achieve precise positioning.

[0101] like Figure 6 As shown, when the external force pushes the tail end of the driving shaft 15, the spring 16 is further compressed, and the driving shaft 15 drives the first elastic stopper 13 and the second elastic stopper 14 away from the product 2 (or the positioning and placement area of ​​the product 2). When the external force disappears, the driving shaft 15 moves under the restoring force of the spring 16, driving the first elastic stopper 13 and the second elastic stopper 14 to approach the product 2 placed on the substrate 10, so that the first elastic stopper 13 and the second elastic stopper 14 are in elastic contact with the product 2, avoiding the impact force caused by the rigid driving structure, and making the contact force between the stopper structure and the product 2 softer.

[0102] Specifically, after the positioning of the product 2 is completed, the compression degree of the spring 16 is greater than the minimum compression degree of the spring 16. The minimum compression degree of the spring 16 is ensured by the limiting effect of the first limiting structure 151.

[0103] The fixed limiting structure can be an integrated structure or a combination of two limiting structures in different directions, such as Figure 6 As shown, it includes a first fixed stopper 11 and a second fixed stopper 12 fixedly mounted on a substrate 10, and the first fixed stopper 11 and the second fixed stopper 12 limit the position of the product 2 from two different directions. The first fixed stopper 11 is a plurality of stopper convex blocks located on one side of the product 2, and the second fixed stopper 12 is a plurality of stopper convex blocks located on the other side of the product 2. The first fixed stopper 11 and the second fixed stopper 12 are used for rough positioning when placing the product 2, and as a positioning reference for fine positioning, they limit the position of the product 2 together with the elastic stopper structure.

[0104] A driving shaft 15 is slidably installed on the base plate 10. The driving shaft 15 is elastically connected to the base plate 10 through a spring 16. The axial displacement of the driving shaft 15 is converted into displacements in two different directions of the first elastic limit member 13 and the second elastic limit member 14 through the first connecting rod structure 18 and the second connecting rod structure 17. The restoring force of the spring 16 is used as a driving force to drive the first elastic limit member 13 and the second elastic limit member 14 to move. Under the elastic force of the spring 16, the first elastic limit member 13, the second elastic limit member 14 and the fixed limit structure are in contact with the outer peripheral surface of the product 2, so as to realize accurate and flexible positioning of the product 2.

[0105] Further, if Figure 6 , Figure 7 As shown, the first connecting rod structure 18 includes a first arm 181 and a second arm 182, one end of the first arm 181 is hinged to the end of the driving shaft 15, the other end of the first arm 181 is hinged to one end of the second arm 182, the other end of the second arm 182 is hinged to the base plate 10, and the first elastic stopper 13 is fixedly mounted on the first arm 181;

[0106] The second connecting rod structure 17 includes swing rods 171 parallel to each other, one end of each swing rod 171 is hinged to the base plate 10, and the two swing rods 171 are respectively hinged to the ends of the moving rod 172, and the two swing rods 171 and the moving rod 172 form a parallelogram connecting rod structure, and the second elastic limiter 14 is fixedly installed on the moving rod 172;

[0107] The middle portion of the swing rod 171 is in transmission connection with the driving shaft 15 .

[0108] The contact structure of the first elastic limiting member 13 and the second elastic limiting member 14 with the product 2 is adapted to the shape of the product 2 .

[0109] The first arm 181 and the second arm 182 form a triangular link structure.

[0110] The transmission connection structure between the swing rod 171 and the drive shaft 15 is as follows: Figure 6 , Figure 7 As shown, it includes a fork 153 fixedly mounted on the drive shaft 15, the depth direction of the groove of the fork 153 is perpendicular to the axis of the drive shaft 15, and also includes a connecting shaft 154 installed on the swing rod 171, the connecting shaft 154 is slidably matched with the groove of the fork 153, when the drive shaft 15 moves, the connecting shaft 154 slides in the groove of the fork 153, drives the swing rod 171 to swing, and changes the position of the moving rod 172.

[0111] Embodiment three:

[0112] On the basis of the second embodiment, in the double transfer platform for loading and unloading products in this embodiment, the outer peripheral surface of the product 2 is a rectangular ring structure as a whole;

[0113] The first elastic limiting member 13 is rod-shaped, one end of the first elastic limiting member 13 is fixedly connected to the first arm 181, the other end of the first elastic limiting member 13 is a first contact portion, and the second elastic limiting member 14 is provided with a second contact portion;

[0114] The first contact portion and the second contact portion are used to contact the outer peripheral surface of the product 2 and correspond to a set of adjacent sides of the rectangle, and the fixed limiting structure corresponds to another set of adjacent sides of the rectangle;

[0115] The second contact portion is a plane, and the plane is parallel to the axis of the driving shaft 15 .

[0116] Among them, the axis of the driving shaft 15, the axis of the moving rod 172 and the second contact portion are all parallel to each other, so that when the driving shaft 15 moves axially, the second contact portion on the second elastic limit member 14 approaches or moves away from the product 2, thereby straightening the product 2 from one side of the product 2.

[0117] The first contact portion at the end of the first elastic limiter 13 is in point contact or line contact with the product 2. When the driving shaft 15 moves axially, the end of the first elastic limiter 13 approaches or moves away from the product 2, cooperating with the planar guiding effect of the second contact portion to achieve bidirectional synchronous adjustment and improve the adjustment efficiency.

[0118] Specifically, the connection between the first elastic limiter 13 and the first arm rod 181 and the connection between the second elastic limiter 14 and the movable rod 172 are both detachably fixed by fasteners, and are both provided with adjustment hole structures for adjusting the fixed positions of the first elastic limiter 13 and the second elastic limiter 14 .

[0119] For product 2 with a rectangular ring structure on the outer circumference, a plane parallel to the axis of the drive shaft 15 is set on the second elastic limit member 14 to align product 2 from one side of product 2, and the first elastic limit member 13 pushes product 2 from the other side of product 2. The first elastic limit member 13 and the second elastic limit member 14 cooperate to achieve two-way synchronous adjustment and improve the adjustment efficiency. At the same time, the elastic limit structure as a whole is semi-circular and surrounds the outer circumference of product 2. The drive shaft 15 is parallel to one side of product 2, thereby reducing the overall structural size of the positioning seat 1 and miniaturizing the double transfer platform.

[0120] Embodiment 4:

[0121] The external force pushing the tail end of the driving shaft 15 can be realized by manual operation. In order to realize the automation of the production process, on the basis of the second embodiment and the third embodiment, as shown in FIG. Figure 2 , Figure 8As shown, the double transfer platform for loading and unloading products in this embodiment also includes an automatic push rod mechanism 8 fixedly arranged between the two first linear drive mechanisms 5, and the automatic push rod mechanism 8 and the third linear drive mechanism 6 correspond to the two ends of the first linear drive mechanism 5 respectively;

[0122] like Figure 8 As shown, the automatic push rod mechanism 8 includes a first push rod 82 and a second push rod 83. The first push rod 82 corresponds to the tail end of the driving shaft 15 of one positioning seat 1, and the second push rod 83 corresponds to the tail end of the driving shaft 15 of another positioning seat 1. The two driving shafts 15 are parallel to each other and face oppositely from head to tail.

[0123] The drive 81 is further included for driving the first push rod 82 and the second push rod 83 to move.

[0124] Specifically, the automatic push rod mechanism 8 is located between two material unloading positions, and the relative position of the driver 81 and the platform body 7 is fixed by a bracket structure, which is not shown in the figure.

[0125] like Figure 8 As shown, the driver 81 can be a pair of rotating clamping cylinders arranged in a mirror image, which respectively drive the first push rod 82 and the second push rod 83 to move.

[0126] The driver 81 can also be a linear driver, and a push rod is fixedly installed at the movable end of the linear driver. The two ends of the push rod are respectively a first push rod 82 and a second push rod 83. During operation, the two positioning seats 1 are not located at the unloading position at the same time, and the automatic push rod mechanism 8 can intermittently push the tail ends of the two driving shafts 15.

[0127] An automatic push rod mechanism 8 is set between the two first linear drive mechanisms 5 to automatically push the drive shaft 15, so that the positioning seat 1 releases the limit on the product 2, and the double transfer platform can be connected to the automatic conveyor line to realize automatic picking and placing of the product 2. At the same time, the tail ends of the drive shafts 15 of the two positioning seats 1 are both facing the first linear drive mechanism 5, so that the structure of the double transfer platform is compact and the space utilization rate is improved.

[0128] The control system of the double transfer platform is electrically connected to the first linear drive mechanism 5, the second linear drive mechanism 4, the third linear drive mechanism 6 and the automatic push rod mechanism 8, and is used to control the automatic operation of the double transfer platform. The control system of the double transfer platform is integrated into the control system of the production line to realize automatic picking, placing and transporting of the product 2 at the unloading position.

[0129] Embodiment five:

[0130] On the basis of the fourth embodiment, in order to further optimize the function of the double transfer platform, improve the space utilization of the double transfer platform, and adapt to the conditions with strict requirements on site space.

[0131] The double transfer platform for loading and unloading products in this embodiment includes a first linear drive mechanism 5 and a third linear drive mechanism 6 which are linear modules.

[0132] Specifically, the linear module can be a screw linear module or a slide cylinder.

[0133] The first linear drive mechanism 5 and the third linear drive mechanism 6 preferably use a lead screw linear module to improve the moving accuracy and facilitate the adjustment of the moving position, so as to adapt to products 2 of different sizes. The product 2 in this embodiment is an LGBT module, and the positioning seat 1 is replaced with corresponding specifications according to the different structural forms of the product 2. The combination of the three-axis module greatly improves the transfer range of the product 2, and facilitates the adaptive adjustment of the spatial position of the working position for different products 2.

[0134] The installation distance of the two second linear drive mechanisms 4 needs to ensure that the two second linear drive mechanisms 4 do not interfere with each other when the two slides 3 intersect. Therefore, the length of the second linear drive mechanism 4 restricts the total size of the double transfer platform in the Y-axis direction. When the standard linear module cannot meet the site requirements, this embodiment further performs a non-standard design on the second linear drive mechanism 4, such as Figure 9-11 As shown, the structure of the second linear drive mechanism 4 includes a bracket 41 installed on the moving part of the first linear drive mechanism 5, and a moving plate 43 is slidably installed on the bracket 41, and the moving plate 43 is used for slidably connecting the slide 3;

[0135] The frame also includes a cylinder 42 fixedly mounted on the bracket 41 and a transmission beam 44 slidably mounted on the bracket 41, an annular synchronous belt 45 is rotatably mounted on the transmission beam 44, a fixed block 46 is fixedly mounted on the synchronous belt 45, the fixed block 46 is fixedly connected to the bracket 41, a follower block 47 is fixedly mounted on the synchronous belt 45, and the follower block 47 is fixedly connected to the moving plate 43;

[0136] The output end of the cylinder 42 is connected to the transmission beam 44 to drive the transmission beam 44 to move, and then the moving plate 43 is driven to move by the rotation of the synchronous belt 45.

[0137] like Figure 9-11 As shown, the cylinder 42, the synchronous belt 45, and the transmission beam 44 are arranged side by side and are all located directly below the moving plate 43. The space occupied by the cylinder 42, the synchronous belt 45, and the transmission beam 44 in the X-axis direction is smaller than the space occupied by the moving plate 43.

[0138] Specifically, the cylinder 42 is a pen-shaped cylinder with a compact structure; the above-mentioned sliding connection methods are all realized by the guide rail and slider connection structure, and the pen-shaped cylinder is connected to the transmission beam 44 through a floating connection block; the moving directions of the output end of the cylinder 42, the transmission beam 44, the follower block 47, and the moving plate 43 are all the same; a pair of synchronous wheels are installed on the transmission beam 44, and the synchronous belt 45 is installed on the pair of synchronous wheels, and the rotation direction of the synchronous belt 45 is consistent with the sliding direction of the above-mentioned sliding connection.

[0139] By converting the linear displacement of the cylinder 42 into the rotational displacement of the synchronous belt 45, the linear displacement of the cylinder 42 is amplified and then transmitted to the movable plate 43. In the case of limited space and without changing the stroke of the second linear drive mechanism 4, the axial length of the cylinder 42 is reduced, the overall size of the second linear drive mechanism 4 is reduced, the cost is reduced, and the space is saved.

[0140] Further, if Figure 9-11 As shown, a support seat 32 is provided on the moving part of the second linear drive mechanism 4, and a plurality of guide rods 31 are provided on the slide 3. The guide rods 31 are slidably connected to the support seat 32. The lower end of the guide rod 31 is located below the support seat 32 and corresponds to the third linear drive mechanism 6.

[0141] like Fig.10 As shown, there are four guide rods 31 in total, which are symmetrically arranged on both sides of the moving direction of the moving part of the second linear drive mechanism 4, and a pair of guide rods 31 on each side are connected by a connecting member 33.

[0142] like Figure 1 As shown, a pair of support plates 61 are provided on the moving part of the third linear drive mechanism 6 , and the two support plates 61 are used to support the slide 3 from both sides of the second linear drive mechanism 4 .

[0143] Specifically, the support plate 61 corresponds to the connecting member 33 . When the moving part of the third linear drive mechanism 6 rises, the support plate 61 contacts the connecting member 33 to lift the slide 3 .

[0144] The above description is an explanation of the present invention, not a limitation of the present invention. The scope of the present invention is defined in the claims. Any form of modification may be made within the scope of protection of the present invention.
