At present, there are still some problems when using the handling mechanism on the market, such as: The patent name disclosed in the prior art with the announcement number "CN103787073B" is "A transport mechanism", which discloses that a grabbing mechanism can grab products, the X-axis motion mechanism is driven by the X-axis cylinder, the Y1-axis motion mechanism is installed on the X-axis motion mechanism through the XY connecting plate, the Y1-axis motion mechanism is driven by the Y1-axis cylinder, and through the Y1-axis guide rail, the Y1-axis motion mechanism realizes the displacement of the product to the part to be installed position, the Y2-axis motion mechanism is installed on the Y1-axis motion mechanism through the YY connecting plate, the Y2-axis motion mechanism is driven by the Y2-axis cylinder, and the Y2-axis motion mechanism realizes the displacement of the product to the part inspection position, the Z-axis motion mechanism is installed on the Y2-axis motion mechanism through the YZ connecting plate, the Z-axis motion mechanism is driven by the Z-axis cylinder, and the Z-axis motion mechanism realizes the grabbing, lifting and pressing down installation of the product, and it transports the product to the detection position, the throwing position and the installation position through the mutual movement of the X-axis motion mechanism, the Y1-axis motion mechanism, the Y2-axis motion mechanism and the Z-axis.

[0003] The patent name disclosed in the prior art with the announcement number "CN113548453A" is "Clamping and Translational Transport Mechanism for Multiple Products", which discloses that a belt is sleeved between the driving pulley and the driven pulley, the driving pulley is rotatably connected to the surface of the driven pulley through the belt, the inside of the slider is slidably connected to the surface of the horizontal rack, the bottom of the slider is fixed to the top of the lower frame by welding, a piston sleeve is sleeved between the telescopic rod and the hydraulic cylinder, the telescopic rod is movably connected to the inner side of the hydraulic cylinder through the piston sleeve, so as to facilitate the adjustment of the position of the mounting seat, and the guide Through holes are provided on both sides of the block, and the guide block is slidably connected to the slide rod through the through holes, which is convenient for clamping the product for translational transportation.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

[0023] A movable slider assembly 301 is installed on the rear side of the mounting frame 3, and the movable slider assembly 301 is slidably connected to the linear guide assembly 2; a driving control mechanism for controlling the movement of the movable slider assembly 301 is installed on the right side of the linear guide assembly 2, and the gravity monitoring assembly includes a connecting column 13 installed at the middle position of the bottom surface of the lifting control horizontal plate 6, and a second through groove 131 is opened inside the connecting column 13, and a gravity sensor 132 is installed inside the lower part of the second through groove 131. A pressing plate 16 with an inverted "U" shape structure is installed at the middle position above the fixed plate 7, and the pressing plate 16 penetrates into the second through groove 131, and a gravity sensor 132 is arranged below the middle position of the pressing plate 16. The four corners of the lower surface of the lifting control horizontal plate 6 are grooved to install a limit slide bar 61, and a slide seat 62 is sleeved on the outer side of the limit slide bar 61. A connecting rod 63 is rotatably connected to the inside of the slide seat 62, and the lower end of the connecting rod 63 is rotatably connected to the upper surface of the fixed plate 7, and the length of the connecting rod 63 is greater than the height of the second through groove 131.

[0024] The left and right sides of the lifting control cross plate 6 are both provided with a first through slot 64, the upper end of the auxiliary supporting mechanism 9 is inserted into the first through slot 64, the upper end of the auxiliary supporting mechanism 9 is arranged in a "T"-shaped structure, and the lower end of the auxiliary supporting mechanism 9 is arranged in an "L"-shaped structure; the upper end length of the auxiliary supporting mechanism 9 is greater than the length of the first through slot 64, the support control component includes a "7"-shaped adjustment frame 12 slidably connected to the inner side of the support frame 1, and the lower side of the adjustment frame 12 is connected to the second driving cylinder 11 installed on the inner side of the lower side of the support frame 1; the interior of the adjustment frame 12 is hollow, and an electric push rod 121 is installed inside the adjustment frame 12; the upper interior of the adjustment frame 12 is penetrated by a regulating cross bar 10 for sliding connection, and the lower sides of the left and right ends of the regulating cross bar 10 are connected to the output end of the electric push rod 121, and a convex plate 91 is installed on the rear side of the auxiliary supporting mechanism 9, and the rear end of the convex plate 91 is penetrated by a regulating cross bar 10 for sliding connection, and the convex plate 91 forms a lifting structure through the regulating cross bar 10.

[0025] First, the entire transport mechanism is moved into the working area. After arriving at the working area, the product to be transported is directly below the fixed plate 7. At this time, the first driving cylinder 5 is started, and the output end of the first driving cylinder 5 drives the lifting control cross plate 6 and the fixed plate 7 to move downward together. At this time, the pressure plate 16 above the clamping sub-plate 17 will apply a pressure to the gravity sensor 132 in the second through groove 131. At this time, the gravity sensor 132 can detect the weight of the fixed plate 7 that does not clamp the product. If the weight detected at this time is T1, the second driving cylinder 11 is started at the same time. The output end of the second driving cylinder 11 drives the adjustment frame 12 and the regulating cross bar 10 to move downward together. The regulating cross bar 10 and the lifting control cross plate 6 have the same descending speed. When the lifting control cross plate 6 drops to a certain height position, the first driving cylinder is stopped. The moving cylinder 5 and the second driving cylinder 11 are used, and then the motor in the fixed plate 7 is started to drive the bidirectional screw 14 to rotate. Then, when the bidirectional screw 14 rotates, it drives the two moving blocks 15 connected by the outer thread to move inward at the same time. At this time, the moving block 15 drives the clamping main board 8 below to move inward, so that the two clamping main boards 8 cooperate with each other to clamp the product. At this time, the rubber pad on the inside of the clamping main board 8 can increase the friction with the product, thereby improving the stability of the clamping of the clamping main board 8. Then start the first driving cylinder 5 and the second driving cylinder 11. As shown above, the first driving cylinder 5 drives the lifting control cross plate 6 to rise. The lifting control cross plate 6 stably drives the fixed plate 7 to rise together through the connecting rod 63 and the connecting column 13, and the second driving cylinder 11 drives the adjustment frame 12 and the regulating cross bar 10 to rise together.

[0026] When the fixed plate 7 drives the product below to rise together, the pressure plate 16 above the clamping sub-plate 17 will apply a pressure to the gravity sensor 132 in the second through groove 131. At this time, the gravity sensor 132 can detect the weight of the fixed plate 7 that has clamped the product. If the detected weight is T2, then T2 minus T1 is the weight of the product. If the weight of the product just exceeds the preset safety load value (for example, when it exceeds the safety load value by less than 3KG), the transportation can continue at this time, and the regulating cross bar 10 and the lifting control cross plate 6 continue to rise synchronously. At this time, the electric push rod 121 can be started, and the electric push rod 121 drives the regulating cross bar 10 to move upward to a certain height. At this time, the regulating cross bar 10 drives the convex plate 91 and the auxiliary supporting mechanism 9 to move upward to a certain height. The upper end of the auxiliary supporting mechanism 9 moves upward in the first through groove 64, and then the lower end of the auxiliary supporting mechanism 9 applies an upward lifting force to both sides of the fixed plate 7, so that the auxiliary supporting mechanism 9 can share part of the weight of the fixed plate 7 and the product, avoiding that all the weight is applied to the lifting control cross plate 6, thereby avoiding deformation or breakage of the frame of the entire conveying mechanism, and failure of the drive system, and will not affect the motion control accuracy of the conveying mechanism, so that the conveying mechanism can stably convey the overloaded product, and then drive the movable slider assembly 301 on the rear side of the mounting frame 3 to slide left and right in the linear guide rail assembly 2 through the drive control mechanism, so as to convey the product (the drive control mechanism and the movable slider assembly 301 are both prior art and will not be introduced in detail here).

[0027] As described above, if the monitored product weight does not exceed the preset safety load value, the handling work can be carried out normally. There is no need to start the electric push rod 121 during the handling process, and the auxiliary supporting mechanism 9 does not apply a lifting force to the fixed plate 7.

[0028] Embodiment 2: The stable transport mechanism for product transport in this embodiment can detect the weight of the product during transport and stop transporting products that exceed the preset safety load value. For specific structure, please refer to the attached Figure 1-Figure 7 As shown, based on the first embodiment, T2 minus T1 is the weight of the product. If the weight of the product exceeds the preset safety load value by a lot (for example, it exceeds the safety load value by more than 3KG), the gravity sensor 132 transmits the signal to the central processing module installed on the outside of the support frame 1. After analysis and comparison, the central processing module controls the alarm installed on the outside of the support frame 1, so that the alarm sounds an alarm for early warning, and then the staff arrives in time to close the transport mechanism, so that the transport mechanism stops the transport work to prevent damage caused by excessive overloading.

[0029] Embodiment 3: The stable transport mechanism for product transport in this embodiment can further improve the stability of the transport mechanism when transporting products on the basis of embodiment 1, so that the products can be transported stably. For the specific structure, refer to the attached Figure 9-14 As shown, a limiting shielding frame 71 with a "U"-shaped structure is installed below the left and right sides of the fixed plate 7, the length of the limiting shielding frame 71 is greater than the length of the auxiliary supporting mechanism 9, and an air storage bag 92 with a rectangular structure is installed above the horizontal plane of the lower end of the auxiliary supporting mechanism 9. A limiting shielding frame 71 is arranged on one side of the air storage bag 92, and a fixed plate 7 is arranged above the air storage bag 92. A connecting hose 93 with an "L"-shaped structure is installed below the air storage bag 92. The spacing between the lifting control horizontal plate 6 and the mounting base plate 4 is greater than the height of the air storage bag 92 in the initial state. An air storage cavity 81 with a rectangular structure is opened inside the upper part of the clamping main board 8, and a self-pushing plate 18 is fitted inside the air storage cavity 81. One side of the self-pushing plate 18 is reset by a reset spring The spring 182 is connected to the air storage chamber 81, and two rack assemblies 181 are symmetrically installed on the other side of the push plate 18. The lower end of the connecting hose 93 passes through the bottom of the auxiliary supporting mechanism 9 and one side of the clamping main board 8 and is inserted into the interior of the air storage chamber 81. The front and rear sides of the clamping main board 8 are slotted with a rotating rod 171, and the outer side of the rotating rod 171 passes through and is fixed with a clamping sub-plate 17. The upper end of the rotating rod 171 is inserted into the groove above the clamping main board 8. The outer side of the upper end of the rotating rod 171 is keyed to a sector gear 172, and the outer side of the sector gear 172 is meshed with a rack assembly 181. The clamping sub-plate 17 forms a rotating structure through the rotating rod 171, and rubber pads for increasing friction are installed on the outer sides of the clamping main board 8 and the clamping sub-plate 17.

[0030] When the lower end of the auxiliary supporting mechanism 9 applies an upward lifting force to the two sides of the fixed plate 7, so that the auxiliary supporting mechanism 9 can share part of the weight of the fixed plate 7 and the product, the fixed plate 7 can squeeze the air storage bag 92 installed above the lower end of the auxiliary supporting mechanism 9. When the fixed plate 7 squeezes the air storage bag 92, the outer side of the air storage bag 92 is limited and blocked by the limiting shielding frame 71 to prevent the volume of the air storage bag 92 from expanding outward when it is squeezed, so that the gas in the air storage bag 92 can enter the air storage chamber 81 through the connecting hose 93 (the principle of the self-propelled plate 18 and the air storage chamber 81 is the same as the principle of the piston-type air push mechanism on the market). At this time, the gas in the air storage chamber 81 can automatically push the self-propelled plate 18 to move. When the self-propelled plate 18 moves, it pulls the reset spring 182 to accumulate force, and the self-propelled plate 18 drives the rack assembly 181 to move together. When the rack assembly 181 moves, it moves with the fan gear 172 is meshed, thereby driving the fan gear 172 to rotate 90°. (By controlling the arc length of the fan gear 172 and the number of the outer serrated blocks, the fan gear 172 can be controlled to rotate 90°, thereby ensuring that the rotating rod 171 rotates 90°), so that the fan gear 172 drives the rotating rod 171 to rotate. At this time, the rotating rod 171 drives the clamping sub-plate 17 to rotate, so that the clamping sub-plate 17 rotates to the same vertical plane as the self-pushing plate 18. At this time, the self-pushing plate 18 and the clamping sub-plate 17 together clamp and transport the product that has just exceeded the preset safety load value. At this time, the self-pushing plate 18 and the clamping sub-plate 17 are used in conjunction with each other, and the rubber pads installed on the outer sides of the self-pushing plate 18 and the clamping sub-plate 17 can increase the contact area with the product during clamping, thereby reducing the pressure, thereby increasing the friction force, and improving the clamping strength of the transport mechanism, thereby further improving the stability of the product during transport.

[0031] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
