Description

Technical Field

[0001] The invention relates to the field of automobile manufacturing auxiliary equipment, in particular to an automobile parts adsorption unit and an adsorption assembly. Background Art

[0002] After the automotive interior parts are injection molded, operations such as burr removal are required. Therefore, the robotic arm will grab the product unloaded by the injection molding machine and place it on the fixture of the cutting platform. The existing clamping methods include clamping and suction. The clamping method needs to act on the edge area of ​​the part, which is not conducive to the cutting of the edge of the part. The suction method can be adsorbed on the bottom of the product, which is convenient for cutting the edge of the product.

[0003] A Chinese patent with announcement number CN210436011U discloses an automobile tail pipe assembly adsorption-type assembly fixture, including a support frame and three vacuum suction cups fixedly arranged on the support frame, the vacuum suction cups are installed under a hollow fixed rod, the fixed rod is installed under a hollow connecting rod, the connecting rod is installed on a hollow connecting seat, the connecting seat is fixed on the support frame, and all the vacuum suction cups are arranged in series.

[0004] The above-mentioned adsorption type fixture has its adsorption holes (vacuum suction cups) fixed on the support frame, and cannot change the horizontal adsorption density and adsorption range and the longitudinal adsorption depth, etc., and cannot simultaneously adapt to the stable adsorption of automotive interior parts with uneven surfaces and large size differences. In order to keep the edges of the automotive interior parts flat after adsorption, the fixture should contact with the different concave and convex surfaces of the parts as much as possible to support and adsorb. The above-mentioned fixture, since the suction cup position and the suction cup height are not adjustable, will result in most of the suction cups being in an empty suction state, and only a few suction cups (there is a probability that there is only one suction cup) being in a working state. Not only can the parts not be stably adsorbed, but also since other suction cups are in an empty suction state, in order to ensure that the suction cups in the working state always have suction, a power device such as a pump is required to provide a continuous and large suction force to maintain it, which consumes a lot of energy. Summary of the invention

[0005] The present invention aims at the disadvantage that the existing adsorption type clamps cannot adjust the adsorption density, adsorption range and adsorption depth. The first purpose of the present invention is to provide an automobile parts adsorption unit with adjustable adsorption range, adsorption density and adsorption depth.

[0006] In order to solve the above technical problems, the present invention is solved by the following technical solutions:

[0007] An automobile parts adsorption unit comprises a deformation frame and a plurality of adsorption parts which can be guided, moved and limited on the deformation frame;

[0008] The deformation frame comprises a first flip frame with an axis hole, a second flip frame with a rotating shaft and plugged and rotated with the axis hole, and a mounting assembly located at the lower end of the rotating shaft and used to mount the deformation frame on a fixed component, a first limiting assembly is arranged between the rotating shaft and the axis hole to limit the position of the first flip frame when the first flip frame rotates a certain angle relative to the second flip frame, the first flip frame can be flipped to be parallel to or in a straight line with the second flip frame, and a second limiting assembly is arranged between the rotating shaft and the mounting assembly to limit the position of the rotating shaft when the rotating shaft rotates a certain angle relative to the fixed component;

[0009] The adsorption part includes a sliding seat, an adsorption tube vertically elastically extended above the sliding seat, and a third limiting component arranged between the sliding seat and the adsorption tube for limiting the position every time the adsorption tube is lifted or lowered by a certain stroke; the lower end of the side wall of the adsorption tube is connected to an air guide tube that passes out of the sliding seat and follows the rise and fall of the adsorption tube; a guide support component for allowing the sliding seat to switch between the first flip frame and the second flip frame and a fourth limiting component for limiting the position every time the sliding seat slides a certain stroke are arranged between the sliding seat and the deformation frame.

[0010] By adopting the above scheme, the adsorption unit is composed of a deformable frame and an adsorption member. In the above deformable frame, the first flip frame and the second flip frame can be switched between different angles. After combining with the installation component, the horizontal plane angle relative to the installation platform can be switched as a whole. The number of adsorption units can be increased on the first flip frame and the second flip frame according to needs. When the first flip frame and the second flip frame are in a straight line, the adsorption member can move and limit the position between the two; when the first flip frame and the second flip frame are at an angle, the adsorption member moves and limits the position on the first flip frame or the second flip frame where it is located, and the adsorption tube can also be raised and lowered. The advantage of such a design is that when adapting to products of different shapes and with different degrees of concave and convex on the surface, the position of the adsorption tube is first changed according to the shape of the product to ensure that all the adsorption tubes can be in sealing contact with the product. When the product is placed on it, The adsorption tube can be adaptively raised and lowered according to the degree of concavity and convexity of the product. After raising and lowering, it can be limited to ensure that the product is in a horizontal state when adsorbed. After the adsorption tube is synchronously connected to a group of air pipes, it only needs to give an initial negative pressure suction force. This suction force can be given by many driving devices such as air cylinders, oil cylinders or electric push rods. There is no need to provide continuous suction force, which can reduce energy consumption. After the product is processed, when the suction force is removed and the product is taken away, the concave and convex surface caused by the shape of the product will be reserved on the adsorption unit. No adjustment is required, and the next product can be directly placed and adsorbed, eliminating the positioning adjustment time required for subsequent products of the same batch and improving the positioning efficiency. When switching to another model of product, it is only necessary to reset the adsorption tube first and adjust the position of the adsorption part according to the shape of the product. The adsorption unit is easy to adjust, saves power, can adapt to products of different shapes and surface concavities, and its adaptability is significantly improved.

[0011] Preferably, two groups of second flip frames are arranged on the rotating shaft at intervals along the axial direction of the rotating shaft, and two groups of first flip frames are correspondingly arranged. The guide support assembly includes guide grooves that are arranged through the side walls of the first flip frames and the second flip frames along their own length directions, guide sliders that are protruded up and down on the side walls of the sliding seat and are respectively embedded in a guide groove for guiding sliding, and support protrusions that are protruded between the two guide sliders on the side walls of the sliding seat and can simultaneously fit with the opposite side of the two first flip frames or the two second flip frames. When the first flip frame and the second flip frame are in a straight line, the two guide grooves are connected, and the sliding seat can slide between the two guide grooves.

[0012] The above scheme is adopted to set up two sets of second flip frames and first flip frames in an upper and lower manner. The advantage is that after two guide sliders are set up on the sliding seat, the sliding of the sliding seat is more stable and space is provided for setting support protrusions. The support protrusions can fill the space between the upper and lower first flip frames and the second flip frames, provide longitudinal support force for the sliding seat in a limited state, and increase the bending resistance of the upper first flip frame and the second flip frame, thereby improving the stability and smoothness of the sliding of the sliding seat.

[0013] Preferably, the fourth limiting assembly includes limiting tooth grooves recessed at intervals along the extension direction of the guide groove on the side opposite to the two first flip frames and the side opposite to the two second flip frames, second limiting tooth blocks that elastically extend and retract on the upper and lower end surfaces of the supporting protrusion and engage or disengage with the opposite limiting tooth grooves during the extension and retraction process, and a fourth driving assembly that drives the two groups of second limiting tooth blocks to extend and retract synchronously, and when the first flip frame and the second flip frame are in a straight line, the limiting tooth grooves are evenly spaced and distributed in a straight line.

The winding shaft of the winding wheel extends beyond the outer wall of the supporting protrusion and a first rotating handle is fixed to the end.

[0015] By adopting the above scheme, only the first rotating handle needs to be rotated to control the synchronous contraction of the two groups of second limit tooth blocks, thereby releasing the limit between the sliding seat and the first flip frame or the second flip frame. The operation is very convenient. Setting two groups of second limit tooth blocks can increase the stability and firmness of the sliding seat when limiting. The matching accuracy between the limit tooth groove and the second limit tooth block can be determined according to the number of limit tooth grooves set. The matching accuracy is relatively high. The above design is not only convenient to operate, but also has good limit stability and high adjustment accuracy.

[0016] Preferably, the first limiting assembly includes a first accommodating groove recessed along the length direction of the first flip frame on the shaft hole, a first limiting block elastically retracted in the first accommodating groove, and a limiting groove recessed circumferentially and evenly spaced on the outer ring wall of the rotating shaft for partial insertion of the first limiting block. A first elastic member is arranged in the first accommodating groove to drive the first limiting block to a partially extended state. The contraction of the first limiting blocks on the two groups of first flip frames is synchronously controlled by a pulling drive member. The pulling drive member includes a connecting rod with two ends fixedly connected to the tail of the side opposite to the two first limiting blocks and a first pull ring protruding outward from the middle of the connecting rod. A clearance groove for the connecting rod to pass through and move horizontally is provided on the side opposite to the two first accommodating grooves.

[0017] By adopting the above scheme, two sets of upper and lower first limit blocks and limit grooves are set, which can significantly increase the firmness of the limit, and the upper and lower two sets of first limit blocks can achieve synchronous contraction by pulling the first pull ring and can automatically extend to maintain the limit again after releasing, which is easy to operate. The number of limit grooves can be set according to needs, and the precision is high. The above design is easy to operate, and the limit is stable and firm.

[0018] Preferably, the mounting assembly comprises a first socket and a second socket with openings facing each other and partially rotating and plugging into each other at the open ends, the opposite ends of the first socket and the second socket are respectively fixedly connected to the lower end of the rotating shaft and a fixing seat having a diameter greater than the diameter of the second socket, the second limiting assembly comprises a first gear groove and a second gear groove respectively arranged in the first socket and the second socket, the relative rotation or locking of the first gear groove and the second gear groove is limited by the extension and retraction of a gear-shaped limiting toothed disc, and the extension and retraction of the limiting toothed disc is controlled by a manual pulling component or an electromagnetic control component.

[0019] Preferably, the manual pulling component comprises a clearance slot vertically penetrating the rotating shaft, a second pull rope passing through the clearance slot and fixed to the upper end of the limiting toothed disc, and a second pull ring fixed to the upper end of the second pull rope, and a third elastic member is arranged on the second pull rope, the two ends of which are respectively in contact with the limiting toothed disc and the bottom of the first gear groove and drive the limiting toothed disc to be plugged into the first gear groove and the second gear groove at the same time;

[0020] The electromagnetic control component includes an electromagnet fixed at the bottom of the second gear slot, a fourth elastic member whose two ends are respectively fixed to the electromagnet and the limiting gear plate and drives the limiting gear plate to be simultaneously plugged into the first gear slot and the second gear slot, an iron sheet is fixed to one end of the limiting gear plate close to the electromagnet, and the extension and retraction of the limiting gear plate is controlled by the power on or off of the electromagnet.

[0021] By adopting the above scheme, the extension and retraction of the limit toothed disc can be controlled manually or by an electromagnet. The electromagnet control is more labor-saving, but the operation is more convenient and the design cost is lower by pulling with the second pull ring. The design of the limit toothed disc, the first gear groove and the second gear groove can improve the angle adjustment accuracy during rotation limit.

[0022] Preferably, the third limiting assembly includes a vertically recessed installation groove on the outer wall of the adsorption tube, a rack fixed in the installation groove, and a first limiting tooth block which is telescopically connected to the side wall of the sliding seat and engages or disengages with the rack during the telescopic process. A screw is rotatably provided at one end of the first limiting tooth block away from the tooth, a threaded hole threadedly connected to the screw is provided on the sliding seat, and one end of the screw away from the first limiting tooth block extends out of the sliding seat and a second rotating handle is fixed to the end.

[0023] By adopting the above solution, the telescopic stroke of the first limiting tooth block can be adjusted through the second rotating handle, and the position can be limited at any time after the adjustment, which is convenient to operate.

[0024] The second purpose of the present invention is to provide an adsorption assembly, including a mounting platform, a plurality of automobile parts adsorption units mounted on the mounting platform, and a switching drive assembly that provides an air pressure switching function for an adsorption component on the mounting platform that needs to provide air pressure changes. The mounting platform is provided with a plurality of mounting grooves in parallel and spaced apart for guiding the sliding movement of the mounting assembly after insertion. The mounting assembly is provided with mounting holes. The mounting platform is provided with a plurality of through holes spaced apart along the length direction of the mounting grooves. The mounting assembly is tightly fitted with the mounting platform by bolts and nuts.

[0025] By adopting the above scheme, a number of automobile parts adsorption units can be flexibly installed on the mounting table according to the shape and area of ​​the product, the position of each group of adsorption units can be adjusted arbitrarily, and an appropriate number of adsorption parts can be selected according to needs. Different adsorption combinations can be formed quickly and flexibly, and it can be adapted to the adsorption and clamping of various parts.

[0026] Preferably, the switching drive assembly includes an air cylinder, a piston sealed and movable in the air cylinder, and an air circuit assembly connected to the end of the air cylinder, the end of the piston away from the air circuit assembly is fixedly connected to the end of the piston rod of the air cylinder or the piston rod of the oil cylinder or the electric push rod, the air circuit assembly includes a main air pipe, a connector and a plurality of branch air pipes evenly distributed on the connector, the end of the branch air pipe is provided with a switching structure which is in a closed state in normal state and in a connected state when the air guide pipe is plugged into the main air pipe, the switching structure includes a baffle which partially seals the end of the branch air pipe, an elastic seal which guides the end of the branch air pipe and can completely block the branch air pipe or partially open the branch air pipe as it shrinks, and a top block is convexly provided on the inner wall of the air guide pipe outlet which can press the elastic seal when the elastic interference sleeve of the air guide pipe is arranged outside the air guide pipe.

[0027] By adopting the above scheme, in the air path assembly, the length of the air distribution pipe only needs to be able to cover the moving range of all sliding seats. When the air distribution pipe is not connected to the air guide pipe, it is in a normally closed state and will not affect the negative pressure state of other air distribution pipes. The air storage cylinder that provides negative pressure only needs to be connected to the air cylinder or oil cylinder or electric push rod, and provide a telescopic force to drive the piston inside the air storage cylinder to move and form a certain negative pressure adsorption force, which is very labor-saving.

[0028] The present invention has significant technical effects due to the adoption of the above technical scheme: a number of automobile parts adsorption units are flexibly installed on the mounting platform according to the shape and area of ​​the product, the position of each group of adsorption units is arbitrarily adjusted, and an appropriate number of adsorption parts are selected according to needs, so that different combinations can be quickly and flexibly formed. The adsorption unit is composed of a deformation frame and an adsorption part. In the above-mentioned deformation frame, the first flip frame and the second flip frame can be switched between different angles. After combining with the installation component, the horizontal plane angle relative to the mounting platform can be switched as a whole. The number of adsorption units can be increased on the first flip frame and the second flip frame according to needs. When the first flip frame and the second flip frame are in a straight line, the adsorption part can be moved and limited between the two; when the first flip frame and the second flip frame are at an angle, the adsorption part moves and limits on the first flip frame or the second flip frame where it is located, and the adsorption tube can also be raised and lowered and limited. The advantage of such a design is that when adapting to products with different shapes and different degrees of concave and convex on the surface First, change the position of the adsorption tube according to the shape of the product to ensure that all the adsorption tubes can be in sealing contact with the product. When the product is placed on it, the adsorption tube will be adaptively raised and lowered according to the degree of concave and convexity of the product. After lifting and lowering, it can be limited to ensure that the product is in a horizontal state when adsorbed. After the adsorption tube is synchronously connected to a group of air pipes, it only needs to give an initial negative pressure suction force. This suction force can be given by many driving devices such as cylinders, oil cylinders or electric push rods. There is no need to provide continuous suction force, which can reduce energy consumption. After the product is processed, when the suction force is removed and the product is taken away, the concave and convex surface caused by the shape of the product will be reserved on the adsorption unit. No adjustment is required, and the next product can be placed and adsorbed directly, eliminating the positioning adjustment time required for subsequent products of the same batch, and improving the positioning efficiency; when switching to another model of product, it is only necessary to reset the adsorption tube first and adjust the position of the adsorption part according to the shape of the product. The adsorption unit is easy to adjust, saves power, and can be adapted to products of different shapes and surface concave and convex degrees, and the adaptability is significantly improved.

[0063] Combination Figure 14~Figure 16 As shown, the gas circuit assembly includes a main gas pipe 48 connected in sequence, an internally hollow connector 49, and a plurality of gas branch pipes 50 evenly distributed on the side of the connector 49 away from the main gas pipe 48.

The end of the gas branch pipe 50 is provided with a switching structure which is in a closed state in a normal state and is in a connected state when the air guide pipe 21 is plugged therewith. The switching structure includes a baffle 51 that partially seals the end of the gas branch pipe 50, a guide elastically retractable at the end of the gas branch pipe 50 and can completely block the gas branch pipe 50 or partially open the gas branch pipe 50 as it shrinks.

The top block 211 presses the plug 52 to connect the air distribution pipe 50 with the air guide pipe 21.

[0064] Combination Figure 17-18As shown, a number of automobile parts adsorption units are flexibly installed on the mounting platform 43 according to the shape and area of ​​the product, the position of each group of adsorption units can be adjusted arbitrarily, and fixed to the mounting platform 43 through the fixing seat 13, and an appropriate number of adsorption pieces can be selected according to needs, so that different combinations can be formed quickly and flexibly. The adsorption unit is composed of a deformation frame and an adsorption piece. In the above-mentioned deformation frame, the first flip frame 1 and the second flip frame 2 can be switched between different angles. After combining with the installation components, the horizontal plane angle relative to the mounting platform can be switched as a whole. The number of adsorption units can be increased on the first flip frame 1 and the second flip frame 2 according to needs. When the first flip frame 1 and the second flip frame 2 are in a straight line, the adsorption piece can move and limit between the two; when the first flip frame 1 and the second flip frame 2 are at an angle, the adsorption piece moves and limits on the first flip frame 1 or the second flip frame 2 where it is located, and the adsorption tube 17 can also be lifted and limited. The advantage of this design is that it can adapt to different shapes and surfaces. When there are products with different concave and convex surfaces, the position of the adsorption tube 17 is first changed according to the shape of the product to ensure that all the adsorption tubes 17 can be in sealing contact with the product. When the product is placed on it, the adsorption tube 17 is adaptively raised and lowered according to the degree of concave and convexity of the product. After lifting and lowering, it can be limited. After the adsorption tube 17 is synchronously connected to a group of air pipes, only an initial suction force needs to be given. This suction force can be given by many driving devices such as cylinder 46, oil cylinder or electric push rod. There is no need for the pump to continuously provide suction power, which can reduce energy consumption. After the product is processed, the suction force is removed and the product is taken away. The concave and convex surface caused by the shape of the product will be reserved on the adsorption unit. No adjustment is required, and the next product can be directly placed and adsorbed, which saves adjustment time and improves positioning efficiency. When switching to another model of product, the adsorption tube 17 can be driven to reset, and the position of the adsorption component can be adjusted according to the shape of the product. The adsorption unit is easy to adjust, saves power, and can be adapted to products of different shapes and surface concave and convex degrees, and the adaptability is significantly improved. Example

[0065] The difference between this embodiment and embodiment 1 is that Figure 19~Figure 20 As shown, the lifting and lowering of the limiting toothed disc 36 is controlled by a manual pulling component.

[0066] The manual pulling component includes a clearance slot 301 vertically passing through the rotating shaft 3, a second pull rope 40 passing through the clearance slot 301 and fixed to the upper end of the limiting gear plate 36, and a second pull ring 42 fixed to the upper end of the second pull rope 40. A third elastic member 39 is provided on the second pull rope 40, whose two ends respectively abut against the bottom of the limiting gear plate 36 and the first gear groove 34 and drive the limiting gear plate 36 to be simultaneously plugged into the first gear groove 34 and the second gear groove 35.

[0067] Compared with electromagnetic control components, manual pulling components have lower installation costs, are equally easy to operate, and do not require charging.

[0068] The first elastic member 26 , the second elastic member 30 , the third elastic member 39 , the fourth elastic member 38 , the fifth elastic member 33 and the sixth elastic member 55 are all springs.

[0069] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
