The conveying mechanism 3 is provided with a loading area, a thickness measuring area and a discharging area in sequence along the conveying direction. The hopper mechanism 1 and the loading mechanism 2 are arranged at the position corresponding to the loading area of ​​the conveying mechanism 3. The hopper mechanism 1 is used to stack the workpieces to be measured. The loading mechanism 2 transfers the workpieces of the hopper mechanism 1 to the loading area. The conveying mechanism 3 drives the workpieces in the loading area to pass through the thickness measuring area and the discharging area in sequence. The thickness measuring mechanism 4 is arranged at the thickness measuring area corresponding to the conveying mechanism 3. The thickness measuring mechanism 4 is used to measure the thickness of each workpiece in the thickness measuring area on the conveying mechanism 3. The unloading mechanism 5 and the discharging mechanism 6 are arranged at the unloading area corresponding to the conveying mechanism 3. The unloading mechanism 5 is used to transfer the workpieces in the unloading area that have passed the thickness measurement to the discharging mechanism 6.

[0025] The thickness measuring mechanism 4 includes at least two thickness measuring pieces, each of which is arranged along the conveying direction of the conveying mechanism 3. Arranging multiple thickness measuring pieces can simultaneously measure the thickness of multiple workpieces in the thickness measuring area, thereby improving the thickness measurement efficiency. The discharging mechanism 6 is provided with at least two discharging partitions. The unloading mechanism 5 transfers the workpieces to the corresponding discharging partitions on the discharging mechanism 6 according to the measured thickness of each workpiece, so that the workers can conveniently classify the workpieces according to the thickness. A defective product outflow area is provided at the conveying end of the conveying mechanism 3, and the products with unqualified thickness measured by the thickness measuring mechanism 4 flow out directly from the conveying end of the conveying mechanism 3.

[0026] See also Figure 1-Figure 3 The silo mechanism 1 includes at least two storage rooms, which are spaces for the silo mechanism 1 to stack workpieces to be measured. In order to meet the material requirements of multiple thickness measuring pieces of the thickness measuring mechanism 4, the loading mechanism 2 includes a loading drive 21 and at least two loading grabbing members 22. The loading drive 21 drives each loading grabbing member 22 to move between the silo mechanism 1 and the loading area, so that the workpiece can be quickly transferred to the upper feeding area to realize loading.

[0027] The distribution direction of each storage chamber of the silo mechanism 1 is parallel to the conveying direction of the conveying mechanism 3, and the distribution direction of each loading grabbing piece 22 of the loading mechanism 2 is also parallel to the conveying direction of the conveying mechanism 3. The number of storage chambers, the number of loading grabbing pieces 22 and the number of thickness measuring pieces are the same, and the distribution intervals of adjacent storage chambers, the distribution intervals of adjacent loading grabbing pieces 22 and the distribution intervals of adjacent thickness measuring pieces are the same. The loading driving piece 21 can drive each loading grabbing piece 22 to move between the silo mechanism 1 and the loading area at the same time, thereby transferring the workpieces in each storage chamber to the loading area at the same time. The loading mechanism 2 can transfer the workpieces corresponding to the number of thickness measuring pieces to the loading area at one time, thereby meeting the needs of the thickness measuring mechanism 4 to measure multiple workpieces at the same time, and effectively improving the thickness measurement efficiency.

[0028] As a preferred embodiment, there are preferably two thickness measuring pieces. In this case, the silo mechanism 1 includes two storage chambers, and the feeding mechanism 2 includes two feeding and grabbing pieces 22 .

[0029] See also Figure 2 The silo mechanism 1 also includes a lifting mechanism, which includes a lifting drive 11 and a lifting member 12. The lifting member 12 is in the form of a lifting plate, a lifting block, etc. Each storage room is provided with a lifting member 12. The lifting drive 11 is a linear motion component in the form of a linear motor module, a cylinder, an electric push rod, etc. The lifting part of the lifting drive 11 is connected to each lifting member 12 and drives each lifting member 12 to move up and down at the same time. The lifting drive 11 drives each lifting member 12 to lift the workpieces stacked in the corresponding storage room to a height suitable for the material loading and grabbing member 22 to grab. The top position of each storage room is also provided with detection components such as proximity switches and optical fiber sensors. The lifting drive 11 cooperates with the detection components to make the topmost workpiece in each storage room at a height suitable for being grabbed by the material loading and grabbing member 22, and can prevent the lifting drive 11 from pushing the workpiece out of the storage room.

[0030] See also Figure 1 and Figure 2 The silo mechanism 1 also includes a storage chamber adjustment mechanism 13, which can be used to adjust the distance between the two storage chambers, thereby leaving enough space for each storage chamber, so that the storage chamber can adapt to workpieces of various sizes. Specifically, the storage chamber adjustment mechanism 13 includes a positive and negative threaded screw rod, which is arranged along the distribution direction of the storage chamber, and the positive and negative threaded screw rods are provided with connecting nuts on the positive and negative threaded sections. The positive and negative threaded screw rods are threadedly matched with each connecting nut, and the two connecting nuts are respectively connected to the two storage chambers. Rotating the positive and negative threaded screw rods can drive the two storage chambers to move closer to or away from each other.

[0031] As a specific example of a storage room, the device of the present application also includes a machine platform, which includes a silo platform and a thickness measuring platform. The silo mechanism 1 is arranged on the silo platform. The silo mechanism 1 includes a back plate, a partition and a baffle. The back plate is vertically installed on the silo platform. A partition is provided on one side of the back plate, and baffles are respectively provided on both sides of the partition. The partition and each baffle are vertically arranged. The area surrounded by the back plate, the partition and the baffle is the storage room. The upper and lower ends of the storage room are open to facilitate the lifting mechanism to lift and push out the workpiece in the storage room. The end of the storage room away from the back plate is open so that the storage room can adapt to workpieces of other sizes by adjusting the spacing between the partition and the baffle. The positive and negative screws are installed on the silo platform through bearings and can rotate relative to the silo platform. The two connecting nuts are respectively connected to the two baffles. Rotating the positive and negative screws can drive the two baffles to be close to the partition or away from the partition, thereby realizing simultaneous adjustment of the spacing and width of the two storage rooms.

[0032] Furthermore, the silo table is also provided with a guide rail, the setting direction of the guide rail is parallel to the length direction of the positive and negative threaded rod, two slide seats are provided on the guide rail, two baffles are respectively provided on the two slide seats, and the positive and negative threaded rod can drive the two baffles to move along the guide rail. In order to facilitate the adjustment of the silo table, the positive and negative threaded rod is provided with a rotating handle, or the positive and negative threaded rod is connected to the rotating part of the rotating power component such as the adjusting motor.

[0033] See also Figure 1 and Figure 3 In order to adapt to the width adjustment of each storage room and enable each loading and grabbing member 22 to stably grab the workpieces in each storage room, the action part of the loading driving member 21 is connected with an adjustment plate 23, and two installation adjustment areas are provided on the adjustment plate 23. The installation adjustment area is provided with an adjustment track, and the adjustment track is parallel to the distribution direction of each storage room. The loading and grabbing member 22 is arranged in the installation adjustment area and moves along the adjustment track for adjustment. When the width of the two storage rooms is adjusted by the storage room adjustment mechanism 13, the distance between the two loading and grabbing members needs to be adjusted in a targeted manner so that the loading and grabbing member 22 can stably grab the workpieces in the storage room.

[0034] Specifically, the adjustment plate 23 is arranged upright and the plate surface of the adjustment plate 23 is parallel to the distribution direction of each storage chamber. The adjustment plate 23 is provided with mounting waist holes at each mounting adjustment area. The mounting waist holes are parallel to the distribution direction of each storage chamber. The loading and grabbing piece 22 is installed to the mounting adjustment area by means of connecting structures such as bolts passing through each mounting waist hole, and can be moved and adjusted along the mounting waist hole.

[0035] See also Figure 1 As a preferred embodiment, there are two silo mechanisms 1 symmetrically distributed on both sides of the loading area, and the two silo mechanisms 1 are backup silo mechanisms 1 for each other. The loading drive 21 drives the loading grabbing member 22 to move between the loading area and the two silo mechanisms 1 and transfer the workpieces of the two silo mechanisms 1 to the loading area of ​​the conveying mechanism 3. The loading drive 21 can be a linear motion component in the form of a linear slide module or the like. The loading drive 21 drives each loading grabbing component 22 to move between the loading area and a silo mechanism 1, and transfers the workpiece of the silo mechanism 1 to the loading area. When the storage chambers of the silo mechanism 1 are empty, the loading drive 21 drives each loading grabbing component 22 to move between the loading area and another silo mechanism 1. At this time, the empty silo mechanism 1 can be replenished. The two silo mechanisms 1 are backup silo mechanisms 1 for each other, which can realize uninterrupted loading of the loading mechanism 2 to the conveying mechanism 3, avoiding equipment shutdown caused by empty silo mechanism 1, ensuring that the equipment can perform thickness measurement work uninterruptedly, and improving the thickness measurement efficiency.

[0036] See also Figure 1 and Figure 4The discharging mechanism 6 includes a discharging conveying member 61, which is a belt conveyor or other form of conveying equipment suitable for conveying workpieces such as thermal insulation pads. A partition stopper 62 is arranged on the conveying surface of the discharging conveying member 61. There are one or more partition stops 62. The partition stops 62 are arranged along the conveying direction of the discharging conveying member 61 and divide the conveying surface of the discharging conveying member 61 into at least two discharging partitions. The discharging conveying member 61 drives the workpiece to move in the corresponding discharging partition. Figure 1 and Figure 4 In the example shown, a partition stopper 62 is provided on the discharge conveyor 61, and the partition stopper 62 divides the conveying surface of the discharge conveyor 61 into two discharge partitions. The two discharge partitions can respectively place workpieces of two thickness ranges, so that workers can classify and sort the workpieces according to their thickness ranges.

The unloading driving member 51 drives the unloading grabbing member 52 to move between the unloading area and each discharging partition. Each workpiece in the unloading area is grabbed by the unloading mechanism 5 and transferred to the corresponding discharging partition according to the thickness measured by the thickness measuring mechanism 4. Further, two discharging mechanisms 6 are provided. The two discharging mechanisms 6 are symmetrically distributed on both sides of the unloading area. The provision of two discharging mechanisms 6 can increase the number of discharging partitions. The unloading driving member 51 drives the unloading grabbing member 52 to move between the unloading area and each discharging partition. Each workpiece in the unloading area is grabbed and transferred to the corresponding discharging partition according to the thickness measured by the thickness measuring mechanism 4. Among them, the workpiece with unqualified thickness is transported to the defective product outflow area by the transport mechanism 3 because it is not grabbed and transferred by the unloading mechanism 5.

[0038] Similar to the loading drive 21, the unloading drive 51 can also be a linear motion component in the form of a linear slide module, and the unloading grabber 52 is connected to the action part of the loading drive 21. Since the thickness of any two adjacent workpieces transported by the conveying mechanism 3 may have a large deviation and need to be placed in different discharge partitions, the action part of the unloading drive 51 is connected to a unloading grabber 52 to realize the partitioned discharge of the workpieces. The detection mechanism measures the thickness of multiple workpieces at the same time and the loading mechanism 2 transfers multiple workpieces to the loading area at the same time. In order to match the thickness measurement speed of the equipment, the unloading mechanism 5 is set to two groups. The two groups of unloading mechanisms 5 work independently and cooperate with each other to transfer each workpiece in the unloading area to the corresponding discharge partition.

[0039] The unloading grabbing member 52 and the loading grabbing member 22 are both workpiece grabbing members 7. The workpiece grabbing member 7 is a tooling suitable for grabbing workpieces such as thermal insulation pads and core materials that need to be measured in thickness.

The telescopic portion of the telescopic member 71 is provided with a suction cup 72. After the workpiece grasping member 7 is driven above the workpiece, the telescopic member 71 extends and uses the suction cup 72 to grasp the workpiece. Then the telescopic member 71 contracts to drive the workpiece to be lifted. At this time, the position of the workpiece can be transferred. After the workpiece is transferred to the corresponding position, the telescopic member 71 extends to drive the workpiece to descend. The suction cup 72 releases the workpiece, and the workpiece can be detached and placed at the designated position. The suction cup 72 is a mature product in the prior art.

[0045] See also Figure 1 and Figure 6 The thickness measuring part includes a thickness measuring frame 41, an upper and lower driving module 42 and a thickness measuring sensor 43. The thickness measuring frame 41 is arranged on the thickness measuring platform. The thickness measuring frame 41 is located on one side of the conveying mechanism 3. The upper and lower driving module 42 is arranged on the thickness measuring frame 41. The upper and lower driving module 42 is a linear motion module such as a vertically arranged linear motor, a cylinder, a hydraulic cylinder, etc. The thickness measuring sensor 43 is connected to the action part of the upper and lower driving module 42 and is driven by the upper and lower driving module 42 to move up and down. The thickness measuring sensor 43 is above the corresponding thickness measuring reference 45. A thickness measuring channel is formed between the thickness measuring sensor 43 and the thickness measuring reference 45 below.

[0046] The thickness sensor 43 is a thickness measuring instrument used to measure the thickness of sheet materials such as thermal insulation pads and core materials. It is a relatively mature product in the prior art, and its structure is not described in detail in this application. The thickness measurement principle is briefly described as follows: the distance between the measuring part of the thickness sensor 43 and the reference plane of the corresponding thickness measurement reference 45 measured by the thickness sensor 43 is taken as the reference value. When there is a workpiece in the thickness measurement channel, the distance between the measuring part of the thickness sensor 43 and the upper end surface of the workpiece is taken as the measurement value. The parameter obtained by subtracting the measurement value from the reference value is the thickness of the workpiece corresponding to the position of the thickness sensor 43.

[0047] In order to improve the accuracy of measuring the thickness of the workpiece, each thickness measuring member is provided with a plurality of thickness measuring sensors 43. When measuring the workpiece, each thickness measuring sensor 43 measures the workpiece, and the average value is taken as the thickness measurement result of the workpiece. As a preferred embodiment, the thickness measuring member includes four thickness measuring sensors 43, and the thickness of the workpiece is analyzed by measuring four points of the workpiece. At the same time, the plurality of thickness measuring sensors 43 can also screen out defective products with excessive thickness deviations at various locations.

[0048] See also Figure 6As a further embodiment, the action part of the upper and lower driving modules 42 is connected to the thickness measuring mounting member 44, and the thickness measuring mounting member 44 is used to install the thickness measuring sensor 43.

There are multiple position adjustment waist holes so that each thickness measuring sensor 43 can be dispersedly arranged.

[0049] In order to realize automatic thickness measurement of the workpiece, a workpiece sensor is provided in the thickness measurement area of ​​the conveying mechanism 3 or on the thickness measurement mounting part 44. The workpiece sensor is a detection element such as a photoelectric switch or a proximity switch, which is used to detect the position of the workpiece on the conveying mechanism 3 so that the conveying mechanism 3 can transport the workpiece to a position suitable for detection by each detection part.

[0050] As a preferred embodiment, the thickness measuring device of the present invention also includes a control system, which can be a PLC system, etc. The control system is connected to the lifting drive 11 and the detection component of the silo mechanism 1 through wired signals or wireless signals to realize the control and detection of the silo mechanism 1; the control system is connected to the feeding drive 21 and each feeding grabbing member 22 of the feeding mechanism 2 through wired signals or wireless signals to realize the control of each feeding grabbing member 22, so that each feeding grabbing member 22 transfers the workpiece from the designated silo mechanism 1 to the conveying mechanism 3; the control system is also connected to the first conveyor 31, the second conveyor 32, the width adjustment mechanism and the workpiece sensor of the conveying mechanism 3 through wired signals or wireless signals to realize the control of the workpiece. The conveying mechanism 3 accurately controls the position of the workpiece transported and adjusts the distance between the two conveyors; the control system is also connected with the upper and lower drive modules 42, thickness measuring sensors 43, etc. of each thickness measuring piece through wired signals or wireless signals to realize the adjustment and control of each thickness measuring sensor 43, and obtain the thickness measurement results of each thickness measuring sensor 43 on the workpiece; the control system is also connected with the unloading drive parts 51 and the unloading grabbing parts 52 of each unloading mechanism 5 through wired signals or wireless signals, so as to control the unloading grabbing parts 52 to transfer the workpiece to the corresponding unloading partition according to the thickness; the control system is also connected with the unloading conveying parts 61 of the unloading mechanism 6 through wired signals or wireless signals, so as to control the movement of each unloading conveying part 61 and output the workpiece.

[0051] By controlling the silo mechanism 1, the loading mechanism 2, the conveying mechanism 3, the thickness measuring mechanism 4, the unloading mechanism 5 and the discharging mechanism 6 in linkage with each other through the control system, it is possible to realize automatic and efficient thickness measurement of the workpieces, and the workpieces can be output in different areas according to their thicknesses. Workers are only responsible for regularly replenishing materials to the silo mechanism 1 and collecting materials from the discharging mechanism 6, and other processes can be completed by the equipment, which reduces the labor intensity and difficulty of workers. It can be used for mass measurement of sheet products such as thermal insulation sheets and core materials.
