Description

Technical Field

[0001] The present invention relates to the technical field of article conveying, and in particular to a conveying device and a conveying method. Background Art

[0002] In the production and transportation link of electric energy meters, double-speed chains are currently used to transport electric energy meters. Double-speed chains, also known as double-speed conveyor lines, are a type of self-flowing assembly line equipment used in the production line of the electronic and electrical industry, used to transport electronic appliances to different workstations for processing.

[0003] For example, the Chinese patent with the authorization announcement number CN210029170U and the name is a stopping and positioning device for an electric energy meter conveyor line. A photoelectric sensor is installed in front of the stopping assembly. The conveyor line conveys the electric energy meter to the position of the photoelectric sensor. The sensor gives a signal, and the first cylinder rises to drive the blocking plate to rise. The blocking plate blocks the electric energy meter to stop the electric energy meter. The second and third electric energy meters are stopped by the second stopping assembly. The third stopping assembly repeats the action of the first stopping assembly, and the three electric energy meters are stopped in sequence.

[0004] In view of the above-mentioned related technologies, a baffle structure is used to limit the electric energy meter. Since the conveying speed of the double-speed chain is relatively fast, when the electric energy meter contacts the baffle, due to the effect of inertia, the electric energy meter will be subjected to a large collision vibration. For example, on some high-speed production lines, the speed of the double-speed chain can reach 20 meters per minute. When the electric energy meter hits the baffle at such a speed, the impact force generated cannot be underestimated. This collision vibration will have a serious impact on the components inside the electric energy meter that have not been fully tightened. The electric energy meter contains many precision components, such as circuit boards, metering chips, etc., which may not have been fully tightened during the assembly process. After being subjected to collision vibration, these components are prone to loosening and displacement. Once the components are loose and displaced, it will directly affect the normal assembly process of the electric energy meter and increase the product's unqualified rate. Summary of the invention

[0005] In view of this, the present invention provides a conveying device and a conveying method, which aim to solve the problem that the internal parts of the electric energy meter are loosened and displaced due to the impact of the baffle, which reduces the accuracy of the electric energy meter equipment and increases the product failure rate.

[0006] To solve the above technical problems, in a first aspect, the present invention provides a conveying device, including a double-speed conveyor line; linear drivers are fixedly connected on both sides of the double-speed conveyor line, and the driving shaft of the linear driver is fixedly connected to a first support plate, and the lower bottom surface of the first support plate is fixedly connected to a transmission plate, and the transmission plate is provided with a first inclined surface, and the first support plate is horizontally slidably connected to a connecting plate, and a buffer spring is arranged between the first support plate and the connecting plate, and the connecting plate is vertically slidably connected to a clamping shell, and the connecting plate can support the clamping shell, and the bottom wall of the clamping shell is vertically slidably connected to a transmission block, and the transmission block is provided with a second inclined surface that can abut against the first inclined surface, and the belt conveyor is used to clamp the electric energy meter to separate from the double-speed conveyor line and make the electric energy meter move smoothly from motion to stillness.

[0007] By adopting the above technical scheme, the squeezing force of the belt conveyor on the electric energy meter is provided by the buffer spring. When the first support plate moves to make the belt conveyor abut against the side wall of the electric energy meter, the squeezing length of the buffer spring gradually increases, thereby enabling the belt conveyor to clamp the electric energy meter, and the clamping force of the belt conveyor on the electric energy meter gradually increases, thereby improving the smoothness of the transition from high speed to low speed of the electric energy meter during transportation. The belt conveyor then makes the electric energy meter stationary at a low speed, thereby improving the stability of the transportation process of the electric energy meter from movement to stillness, reducing the probability of position error caused by the shaking of internal parts of the electric energy meter due to sudden stop, and improving the processing accuracy of the electric energy meter.

[0008] Optionally, the outer side surface of the connecting plate is fixedly connected to a support portion, the outer side surface of the clamping shell is fixedly connected to an upper support block and a lower support block, a first sliding rod is fixedly connected between the upper support block and the lower support block, and the first sliding rod is slidably connected to the support portion.

[0009] Optionally, a support tube is fixedly connected to the outer side surface of the connecting plate, and the support tube is sleeved on the outside of the buffer spring. The support tube can move and abut against the first support plate.

[0010] By adopting the above technical solution, when the support tube abuts against the first support plate, the transmission of force between the first support plate and the connecting plate transitions from the soft support mode of the buffer spring to the hard support mode of the support tube, thereby improving the reliability and stability of the belt conveyor clamping and fixing the electric energy meter.

[0011] Optionally, the belt conveyor includes a rotating source fixedly connected to a clamping shell and a driving wheel and a driven wheel rotatably arranged in the clamping shell, the driving wheel is fixedly sleeved on a driving shaft of the rotating source, and a conveyor belt is sleeved on the outer side surfaces of the driving wheel and the driven wheel.

[0012] Optionally, a plurality of support rollers are rotatably connected in the clamping shell, and the support rollers abut against the inner side surfaces of the conveyor belt.

[0013] By adopting the above technical solution, the support roller supports the conveyor belt, reducing the deformation of the conveyor belt when clamping the electric energy meter, and improving the reliability and stability of the conveyor belt clamping and fixing the electric energy meter.

[0014] Optionally, the transmission block can also slide in the horizontal direction, and the lower bottom surface of the clamping shell is hinged with a first support plate. The horizontal movement of the transmission block can push the first support plate to rotate, so that the first support plate abuts against the lower bottom surface of the electric energy meter.

[0015] By adopting the above technical solution, the transmission block moves horizontally and lifts the electric energy meter upward through the transmission block and the clamping shell. At the same time, the transmission block can also drive the first support plate through the transmission block, so that the first support plate supports the electric energy meter, thereby reducing the probability of the electric energy meter falling off the belt conveyor. When the electric energy meter is subjected to downward force during subsequent processing, the first support plate supports the electric energy meter upward, thereby improving the stability of the electric energy meter during processing.

[0016] Optionally, a first sliding groove is vertically opened on the bottom wall of the clamping shell, a second sliding groove is horizontally opened on the upper surface of the transmission block, and a second sliding rod is slidably arranged inside the first sliding groove and the second sliding groove.

[0017] Optionally, a first sensor is provided on the double-speed conveyor line, and a second sensor is provided on the belt conveyor, and the first sensor and the second sensor are used to detect the position of the electric energy meter.

[0018] By adopting the above technical solution, the first sensor measures the position of the electric energy meter and transmits the electrical signal to the linear drive to start the linear drive. When the electric energy meter moves to the position to be processed, the second sensor transmits the electrical signal to the belt conveyor to stop the belt conveyor and the electric energy meter continues to be processed.

[0019] In a second aspect, the present invention provides a conveying method of a conveying device, which is applied to a conveying device described in the first aspect, and the conveying method is: S1, the double-speed transmission line transmits the electric energy meter, and the first sensor measures the position of the electric energy meter and transmits the electrical signal to the linear drive; S2, the linear drive is started to move the belt conveyor to clamp the electric energy meter through the first support plate, the buffer spring, the connecting plate and the clamping housing; S3, the first support plate drives the transmission plate to move, the transmission plate pushes the transmission block through the first inclined surface and the second inclined surface, the transmission block pushes the clamping shell and the belt conveyor upward, the belt conveyor decelerates the electric energy meter and drives the electric energy meter to move upward, so that the electric energy meter is separated from the double-speed conveyor line; S4, the transmission plate moves through the first inclined surface and the second inclined surface to push the transmission block, so that the transmission block pushes the second support plate to rotate, and the second support plate is lifted upward to support the electric energy meter during the rotation process.

[0020] S5, the second sensor transmits an electrical signal to the belt conveyor, causing the belt conveyor to stop running, and the electric energy meter continues to be processed.

[0021] By adopting the above technical solution, after the belt conveyor changes the electric energy meter on the double-speed conveyor line from high speed to low speed, the belt conveyor then clamps the electric energy meter upwards, so that the deceleration process of the electric energy meter can be carried out stably.

[0022] In summary, compared with the prior art, the present invention includes at least one of the following beneficial technical effects: 1. The extrusion force of the belt conveyor on the electric energy meter is provided by the buffer spring. When the first support plate moves to make the belt conveyor abut against the side wall of the electric energy meter, the length of the buffer spring being squeezed gradually increases, thereby enabling the belt conveyor to clamp the electric energy meter, and the clamping force of the belt conveyor on the electric energy meter gradually increases, thereby improving the smoothness of the transition from high speed to low speed of the electric energy meter during transportation. The belt conveyor then makes the electric energy meter stationary at a low speed, thereby improving the stability of the transportation process from motion to stillness of the electric energy meter, reducing the probability of position error caused by the shaking of internal parts of the electric energy meter due to sudden blocking, improving the processing accuracy of the electric energy meter, and helping to maintain the qualified rate of the product.

[0023] 2. When the transmission block moves horizontally and lifts the electric energy meter upward through the clamping shell and the belt conveyor, the transmission block can also drive the second support plate to rotate so that the second support plate supports the electric energy meter, thereby reducing the probability of the electric energy meter falling off the belt conveyor. When the electric energy meter is subjected to downward force during subsequent processing, the second support plate supports the electric energy meter upward, thereby improving the stability of the electric energy meter during processing.

DETAILED DESCRIPTION

[0026] To make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the following will be combined with the embodiments of the present invention. Figure 1-Figure 6 , the technical scheme of the embodiment of the present invention is clearly and completely described. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention.

[0027] In a first aspect, this embodiment provides a conveying device, referring to Figure 1 , Figure 2 and Figure 3 A conveying device includes a double-speed conveying line 1, a linear drive 2, a first support plate 21, a transmission plate 22, a connecting plate 23, a buffer spring 24, a clamping shell 25, a transmission block 26 and a belt conveyor 4.

[0028] Reference Figure 1 , Figure 2 and Figure 4 The double-speed conveyor line 1 is erected on a horizontal plane for conveying an electric energy meter 3. Two linear actuators 2 are provided and distributed on both sides of the double-speed conveyor line 1. The two linear actuators 2 are arranged opposite to each other. The first support plate 21 is fixedly connected to the driving shaft of the linear actuator 2, and the transmission plate 22 is fixedly connected to the bottom surface of the first support plate 21. The side of the transmission plate 22 away from the first support plate 21 is provided with a first inclined surface 221.

[0029] Reference Figure 3 and Figure 4 The side of the connecting plate 23 is fixedly connected with a third slide bar 27, and the connecting plate 23 is horizontally slidably connected with the first support plate 21 through the third slide bar 27. The buffer spring 24 is sleeved on the outer side of the third slide bar 27, and the buffer spring 24 is arranged between the first support plate 21 and the connecting plate 23. The outer side of the connecting plate 23 is fixedly connected with a support portion 231, and the outer side of the clamping shell 25 is fixedly connected with an upper support block 252 and a lower support block 253, and a first slide bar 254 is fixedly connected between the upper support block 252 and the lower support block 253. The first slide bar 254 is vertically slidably connected with the support portion 231, thereby the clamping shell 25 is vertically slidably connected with the connecting plate 23. When the upper support block 252 falls to the support portion 231, the connecting plate 23 supports the clamping shell 25 upward.

[0030] Reference Figure 3 and Figure 5 The transmission block 26 is slidably connected to the lower bottom surface of the clamping shell 25. The bottom wall of the clamping shell 25 is vertically provided with a first slide groove 251. The upper surface of the transmission block 26 is horizontally provided with a second slide groove 262. The first slide groove 251 and the second slide groove 262 are slidably provided with a second slide rod 263 inside, so that the transmission block 26 can slide in the vertical and horizontal directions. The transmission block 26 is provided with a second inclined surface 261 that can abut against the first inclined surface 221. The belt conveyor 4 is fixedly connected to the inside of the clamping shell 25. The belt conveyor 4 is horizontally arranged and used to clamp the electric energy meter 3 on the surface of the double-speed conveyor line 1. The running speed of the belt conveyor 4 is lower than the running speed of the double-speed conveyor line 1. A first sensor 8 is arranged on the double-speed conveyor line 1, and a second sensor 9 is arranged on the belt conveyor 4. The first sensor 8 and the second sensor 9 are used to detect the position of the electric energy meter 3.

[0031] The double-speed conveyor line 1 conveys the electric energy meter 3. When the electric energy meter 3 is conveyed to the fixed position of the belt conveyor 4, the first sensor 8 measures the position of the electric energy meter 3 and transmits the electrical signal to the linear drive 2. The linear drive 2 is started, and the driving shafts of the two linear drives 2 move toward the inside of the double-speed conveyor line 1. The driving shaft of the linear drive 2 pushes the first support plate 21 to move. The first support plate 21 pushes the connecting plate 23 to move through the buffer spring 24. The clamping shell 25 and the belt conveyor 4 move synchronously with the connecting plate 23. The two belt conveyors 4 move closer to each other and abut against the side of the electric energy meter 3. The first support plate 21 continues to move, so that the buffer spring 24 is gradually compressed. At this time, the extrusion force of the belt conveyor 4 on the electric energy meter 3 gradually increases. When the buffer spring 24 is compressed to a certain extent, the belt conveyor 4 clamps the electric energy meter 3.

[0032] During the movement of the first support plate 21, the transmission plate 22 is driven to move synchronously, the first inclined surface 221 moves synchronously with the transmission plate 22, the movement of the first inclined surface 221 pushes the second inclined surface 261 to move vertically upward, the transmission block 26 moves upward with the second inclined surface 261 and pushes the clamping housing 25 and the belt conveyor 4 to move upward, the belt conveyor 4 clamping the electric energy meter 3 drives the electric energy meter 3 to move upward, so that the electric energy meter 3 is separated from the double-speed conveyor line 1. At this time, the belt conveyor 4 drives the electric energy meter 3 to move, and the second sensor 9 detects the position of the electric energy meter 3. When the electric energy meter 3 moves to the position to be processed, the second sensor 9 transmits an electrical signal to the belt conveyor 4, so that the belt conveyor 4 stops running, and the electric energy meter 3 continues to be processed.

[0033] The squeezing force of the belt conveyor 4 on the electric energy meter 3 is provided by the buffer spring 24. When the first support plate 21 moves to make the belt conveyor 4 abut against the side wall of the electric energy meter 3, the squeezing length of the buffer spring 24 gradually increases, thereby enabling the belt conveyor 4 to clamp the electric energy meter 3, and the clamping force of the belt conveyor 4 on the electric energy meter 3 gradually increases, thereby improving the smoothness of the transition from high speed to low speed of the electric energy meter 3 during transportation. The belt conveyor 4 then makes the electric energy meter 3 stationary at a low speed, thereby improving the stability of the transportation process from movement to stillness of the electric energy meter 3, reducing the probability of position error caused by the sudden stop of the electric energy meter 3 and the shaking of internal parts, thereby improving the processing accuracy of the electric energy meter 3.

[0034] When the connecting plate 23 supports the clamping shell 25 upward, there is a gap between the clamping shell 25 and the transmission block 26. When the linear drive 2 drives the clamping shell 25 to move through the first support plate 21, the transmission plate 22 moves synchronously with the first support plate 21. The transmission plate 22 drives the transmission block 26 to move upward through the first inclined surface 221 and the second inclined surface 261. Since the transmission block 26 is slidably connected to the clamping shell 25 through the second sliding rod 263 and the first sliding groove 251, and there is a gap between the clamping shell 25 and the transmission block 26 at this time, the upward movement of the transmission block 26 will not push the clamping shell 25 to move upward during the initial movement of the clamping shell 25 close to the electric energy meter 3. When the belt conveyor 4 clamps the electric energy meter 3, the linear drive 2 continues to push the first support plate 21 to move, so that the buffer spring 24 is continuously compressed. At this time, the transmission plate 22 drives the transmission block 26 to move upward through the first inclined surface 221 and the second inclined surface 261. The transmission block 26 moves upward to abut against the clamping shell 25 and drives the clamping shell 25 to move upward. The belt conveyor 4 moves synchronously with the clamping shell 25 to drive the electric energy meter 3 to move upward and leave the double-speed conveyor line 1.

[0035] Thus, after the belt conveyor 4 changes the electric energy meter 3 on the double-speed conveyor line 1 from high speed to low speed, the belt conveyor 4 then clamps the electric energy meter 3 upwards, so that the deceleration process of the electric energy meter 3 can proceed stably.

[0036] Reference Figure 3 and Figure 4 The outer side of the connecting plate 23 is fixedly connected with a support tube 5, which is sleeved on the outside of the buffer spring 24. The support tube 5 can move and abut against the first support plate 21. When the belt conveyor 4 abuts against the electric energy meter 3, the linear drive 2 pushes the first support plate 21 to continuously squeeze the buffer spring 24 until the support tube 5 abuts against the first support plate 21. At this time, the force transmission between the first support plate 21 and the connecting plate 23 is transitioned from the soft support mode of the buffer spring 24 to the hard support mode of the support tube 5, which improves the reliability and stability of the belt conveyor 4 clamping and fixing the electric energy meter 3.

[0037] Reference Figure 6 The belt conveyor 4 includes a rotation source 41, a driving wheel 42, a driven wheel 43 and a conveyor belt 44. The rotation source 41 is fixedly connected to the upper surface of the clamping shell 25, the driving wheel 42 and the driven wheel 43 are rotatably connected inside the clamping shell 25, the driving wheel 42 is fixedly sleeved on the driving shaft of the rotation source 41, and the conveyor belt 44 is sleeved on the outer side surfaces of the driving wheel 42 and the driven wheel 43. The rotation source 41 drives the conveyor belt 44 to run through the driving wheel 42. A plurality of support rollers 6 are rotatably connected inside the clamping shell 25, the support rollers 6 abut against the inner side surfaces of the conveyor belt 44, and the support rollers 6 support the conveyor belt 44, thereby reducing the deformation of the conveyor belt 44 when clamping the electric energy meter 3, and improving the reliability and stability of the conveyor belt 44 clamping and fixing the electric energy meter 3.

[0038] Reference Figure 3 and Figure 4 The lower bottom surface of the clamping housing 25 is hinged with the second support plate 7 through the rotating pin 71. The transmission plate 22 moves through the first inclined surface 221 and the second inclined surface 261 to push the transmission block 26 to move horizontally along the second slide groove 262 close to the double-speed conveyor line 1. The horizontal movement of the transmission block 26 can push the second support plate 7 to rotate clockwise around the rotating pin 71 (refer to Figure 4 ), so that the end of the transmission block 26 close to the double-speed conveyor line 1 is lifted upward while rotating, thereby making the second support plate 7 abut against the lower bottom surface of the electric energy meter 3.

[0039] The transmission block 26 moves horizontally and lifts the electric energy meter 3 upward through the clamping shell 25 and the belt conveyor 4. At the same time, the transmission block 26 can also drive the second support plate 7 to rotate so that the second support plate 7 supports the electric energy meter 3, thereby reducing the probability of the electric energy meter 3 falling off the belt conveyor 4. When the electric energy meter 3 is subjected to a downward force during subsequent processing, the second support plate 7 supports the electric energy meter 3 upward, thereby improving the stability of the electric energy meter 3 during processing.

[0040] The implementation principle of a conveying device in an embodiment of the present invention is as follows: the double-speed conveyor line 1 conveys the electric energy meter 3, and the first sensor 8 measures the position of the electric energy meter 3 and transmits the electrical signal to the linear actuator 2. The linear actuator 2 is started, and the driving shaft of the linear actuator 2 drives the belt conveyor 4 to move and clamp the electric energy meter 3 through the first support plate 21, the buffer spring 24, the connecting plate 23 and the clamping shell 25. During the movement of the first support plate 21, the transmission plate 22 is driven to move synchronously, and the transmission plate 22 pushes the transmission block 26 to move through the first inclined surface 221 and the second inclined surface 261. The transmission block 26 pushes the clamping shell 25 and the belt conveyor 4 upward, and the belt conveyor 4 decelerates the electric energy meter 3 and drives the electric energy meter 3 to move upward, so that the electric energy meter 3 is separated from the double-speed conveyor line 1. The transmission plate 22 moves through the first inclined surface 221 and the second inclined surface 261 to push the transmission block 26 to move horizontally close to the double-speed conveyor line 1, and the transmission block 26 pushes the second support plate 7 to rotate, so that the end of the second support plate 7 close to the double-speed conveyor line 1 is lifted upward to support the electric energy meter 3. The second sensor 9 transmits the electrical signal to the belt conveyor 4 to stop the belt conveyor 4 from running, while the electric energy meter 3 continues to be processed.

[0041] In a second aspect, an embodiment of the present invention provides a conveying method of a conveying device, which is applied to a conveying device in the first aspect, and the conveying method is: S1, the double-speed transmission line 1 transports the electric energy meter 3, and the first sensor 8 measures the position of the electric energy meter 3 and transmits the electrical signal to the linear drive 2; S2, the linear drive 2 is started to move the belt conveyor 4 to clamp the electric energy meter 3 through the first support plate 21, the buffer spring 24, the connecting plate 23 and the clamping housing 25; S3, the first support plate 21 drives the transmission plate 22 to move, the transmission plate 22 pushes the transmission block 26 through the first inclined surface 221 and the second inclined surface 261, the transmission block 26 pushes the clamping housing 25 and the belt conveyor 4 upward, the belt conveyor 4 decelerates the electric energy meter 3 and drives the electric energy meter 3 to move upward, so that the electric energy meter 3 is separated from the double-speed conveyor line 1; S4, the transmission plate 22 moves through the first inclined surface 221 and the second inclined surface 261 to push the transmission block 26, so that the transmission block 26 pushes the second support plate 7 to rotate. During the rotation process, the second support plate 7 is lifted upward to support the electric energy meter 3.

[0042] S5, the second sensor 9 transmits an electrical signal to the belt conveyor 4, so that the belt conveyor 4 stops running, and the electric energy meter 3 continues to be processed.

[0043] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0044] The above are preferred embodiments of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
