Description

Technical Field

[0001] This utility model relates to the field of sheet material processing technology for vacuum forming machines, specifically to a sheet material detection device and a feeding mechanism for vacuum forming machines. Background Technology

[0002] Currently, the vacuum forming machines used in the refrigerator manufacturing industry use PS plastic sheets as raw materials, each sheet being approximately 3-4mm thick. During operation, 200-300 sheets are typically stacked at the loading station awaiting feeding. The vacuum forming machine's suction device then picks up each sheet one by one. However, due to the physical properties of PS plastic, multiple sheets are difficult to separate due to electrostatic adhesion. This causes the suction device to be affected by the static electricity between the sheets, resulting in multiple sheets being picked up at once and heated by the machine for a fixed period. The problem is that the increased thickness of the sheets leads to insufficient softening temperature, resulting in defective products during the vacuum forming process.

[0003] Therefore, it is necessary to improve the existing technology to overcome the aforementioned defects. Utility Model Content

[0004] In view of this, the present application provides a sheet metal testing device to solve at least one problem existing in the prior art, comprising:

[0005] A drive assembly, including a mounting base and a cylinder mounted on the mounting base;

[0006] The detection assembly includes a hanger connected to the cylinder and a detection element disposed on the hanger. The hanger can be driven by the cylinder to rotate the detection element so that the detection element has an initial position and a detection position. When the detection element is in the detection position, it can detect the target board material.

[0007] A transmission assembly connects the cylinder and the detection assembly to convert the linear motion of the cylinder into the rotational motion of the detection assembly.

[0008] Optionally, in the above-mentioned sheet metal testing device, the testing component includes a transmitter and a receiver disposed on the hanger, and there is a gap between the transmitter and the receiver;

[0009] When the testing component is located at the testing position, the target plate is within the spacing.

[0010] Optionally, in the above-mentioned sheet metal testing device, the testing component is an ultrasonic sensor.

[0011] Optionally, in the above-mentioned sheet metal testing device, the transmission assembly includes a spherical bearing connected to the output shaft of the cylinder and a transmission component connecting the spherical bearing and the hanger;

[0012] The spherical bearing includes a connecting end and a movable end. The connecting end is fixedly connected to the cylinder output shaft, and the inner ring of the movable end is connected to a connecting shaft. The transmission component connects the connecting shaft to the hanger.

[0013] Optionally, the above-mentioned sheet metal testing device further includes a connecting component that connects the transmission component and the testing component;

[0014] The connecting assembly includes a rotating shaft and a deep groove ball bearing sleeved on the outside of the rotating shaft. One end of the rotating shaft is connected to a fixed base, and the other end is connected to the hanger. The transmission component connects the rotating shaft and the connecting shaft.

[0015] Optionally, in the above-mentioned sheet metal inspection device, the transmission component includes a rack connected to the cylinder and a gear connected to the hanger. The rack meshes with the gear so that the cylinder drives the rack to move linearly, thereby driving the meshing gear and the hanger connected to the gear to rotate.

[0016] This application also discloses a feeding mechanism for a vacuum forming machine, which includes at least the sheet material detection device as described in any one of the above-mentioned methods.

[0017] Optionally, the above-mentioned feeding mechanism for a vacuum forming machine further includes:

[0018] Mounting rack;

[0019] An adsorption device, installed on the mounting frame, is used to adsorb the board material. It includes a mounting part, a mounting plate installed on the mounting part, and at least one suction cup. At least one suction cup and the board material detection device are both installed on the mounting plate.

[0021] Optionally, in the above-mentioned vacuum forming machine feeding mechanism, the adsorption device further includes a copper sleeve mounted on the mounting plate, and the cylinder is connected to the mounting plate through the copper sleeve.

[0022] Compared with existing technologies, this application has the following advantages: By setting a drive component, a detection component, and a transmission component connecting the drive component and the detection component near the sheet material, the transmission component can convert the linear motion of the cylinder of the drive component into the rotational motion of the detection component. This allows the detection component to rotate to the detection position and detect the thickness of the sheet material. When the detection component detects that the sheet material thickness is the target thickness, the sheet material that meets the requirements is loaded. When the detection component detects that the sheet material thickness is greater than the target thickness, it alerts the operator to take relevant actions, thereby preventing the problem of high defect rates caused by processing multiple sheets at once. Furthermore, the device consists of a drive component, a detection component, and a transmission component, and its structure is relatively simple. Compared with complex traditional detection devices, the manufacturing cost is lower, and the maintenance difficulty and cost of the equipment are also reduced. Attached Figure Description

[0036] To fully understand this application, detailed steps and structures will be presented in the following description to illustrate the technical solution of this application. Preferred embodiments of this application are described in detail below; however, in addition to these detailed descriptions, this application may have other implementation methods.

[0037] Please refer to Figures 1-3 As shown in the preferred embodiment of this application, a sheet material detection device 3 is suitable for installation on the feeding mechanism 200 of a vacuum forming machine. This facilitates the detection of the sheet material 100 fed by the feeding mechanism 200, preventing the feeding mechanism 200 from absorbing multiple sheet materials 100 at once, thus avoiding the production of defective products. In other embodiments, the sheet material detection device 3 can also be installed on other equipment; therefore, the specific industry and field of application for this sheet material detection device 3 are not limited here.

[0038] The vacuum forming machine's feeding mechanism 200 includes a mounting frame 1 and an adsorption device 2 mounted on the mounting frame 1. The adsorption device 2 includes a mounting section 21, a mounting plate mounted on the mounting section 21, and at least one suction cup 22. Both the suction cup 22 and a sheet material detection device 3 are mounted on the mounting plate. The suction cup 22 generates adsorption force to adsorb stacked sheets 100, separating the upper sheet 100 from other sheets. The sheet material detection device 3 detects the thickness of the sheet material 100 adsorbed by the suction cup 22. The process is as follows: After the suction cup 22 picks up the board 100 and rises 100mm, the board detection device 3 detects whether multiple boards 100 have been picked up. If the detection result is equal to the target thickness, that is, the board 100 picked up by the suction cup 22 is a single board, the detection device 3 returns to its original position and the suction cup 22 continues to rise; if the detection result is greater than the target thickness, that is, the board 100 picked up by the suction cup 22 is multiple boards, the detection device 3 returns to its original position, the suction cup 22 releases the vacuum, the board 100 falls back to its original position, and the suction cup 22 repeats the descent to pick up the board 100 a second time.

[0039] Preferably, the adsorption device 2 is movably connected to the mounting frame 1 to allow the adsorption device 2 to move relative to the mounting frame 1 and adapt to different specifications of the board material 100. It is worth noting that since both the detection device 3 and the suction cup 22 are mounted on the mounting plate, when dealing with different specifications of board material 100, it is not necessary to move the detection device 3 and the adsorption device separately; the positions of the detection device 3 and the suction cup 22 can be adjusted simultaneously with a single movement.

[0040] As described above, the board material inspection device 3 includes a drive assembly 31, an inspection assembly 32, and a transmission assembly 33. The drive assembly 31 includes a mounting base 311 and a cylinder 312 mounted on the mounting base 311. The inspection assembly 32 includes a hanger 321 connected to the cylinder 312 and an inspection element 322 mounted on the hanger 321. The hanger 321 can be driven by the cylinder 312 to rotate the inspection element 322, giving the inspection element 322 an initial position A and an inspection position B. When the inspection element 322 is in inspection position B, it can inspect the target board material 100. The transmission assembly 33 connects the cylinder 312 and the inspection assembly 32 to convert the linear motion of the cylinder 312 into the rotational motion of the inspection assembly 32.

[0041] In this embodiment, the detection element 322 includes a transmitter 3221 and a receiver 3222 mounted on the hanger 321, with a gap between them. When the detection element 322 is at detection position B, the target board 100 is within the gap. It should be noted that in this embodiment, the detection element 322 is an ultrasonic sensor. The advantage of this arrangement is that the ultrasonic sensor can perform non-contact detection of the board 100 without damaging its surface. Furthermore, by adjusting the position and angle of the hanger 321 or the detection element 322, detection of boards 100 of different specifications can be achieved, enhancing detection flexibility.

[0042] In other embodiments, the detection element 322 can also be configured as other detectors, such as a laser displacement sensor. This sensor emits a laser beam onto the surface of the object being measured, receives the reflected laser light, and calculates the distance between the object and the sensor based on information such as the laser's time of flight or phase difference, thereby determining the thickness of the plate 100. The type of detection element 322 is not limited here and depends on the specific circumstances.

[0043] In this embodiment, the transmission assembly 33 includes a spherical bearing 331 connected to the output shaft of the cylinder 312 and a transmission component connecting the spherical bearing 331 and the hanger 321. The spherical bearing 331 includes a connecting end 3311 and a movable end 3312. The connecting end 3311 is fixedly connected to the output shaft of the cylinder 312, and the inner ring of the movable end 3312 is connected to a connecting shaft 3313. The transmission component connects the connecting shaft 3313 and the hanger 321.

[0044] Specifically, the detection device 3 also includes a connecting component 4 that connects the transmission component 33 and the detection component 32. The connecting component 4 includes a rotating shaft 41 and a deep groove ball bearing 42 sleeved on the outside of the rotating shaft 41. One end of the rotating shaft 41 is mounted on a fixed seat, and the other end is connected to the hanger 321. The transmission component connects the rotating shaft 41 and the connecting shaft 3313, so that the cylinder 312 can drive the spherical bearing 331 to move horizontally, thereby driving the connecting shaft 3313 mounted on the inner ring of the movable end 3312 to rotate. Under the action of the transmission component, the rotating shaft 41 connected to the transmission component is also driven to rotate, thereby causing the hanger 321 connected to the rotating shaft 41 to drive the detection component 322 to switch between the initial position A and the detection position B. In this embodiment, the spherical bearing 331 can withstand certain radial and axial loads, ensuring the stability of the transmission. At the same time, the flexible joint structure makes the transmission smoother and improves the detection efficiency.

[0045] In other embodiments, the transmission assembly 33 may also be configured to include a rack connected to the cylinder 312 and a gear connected to the hanger 321, with the rack and gear meshing so that the cylinder 312 drives the rack to move linearly, thereby driving the meshing gear and the hanger 321 connected to the gear to rotate, which can also achieve the above-mentioned effect.

[0046] In this embodiment, the adsorption device 2 further includes a copper sleeve 23 mounted on the mounting plate, through which the cylinder 312 is connected to the mounting plate. The copper sleeve 23 has good wear resistance and thermal conductivity, which can reduce friction between the cylinder 312 and the mounting plate, extending the service life of the equipment. At the same time, the copper sleeve 23 can also play a certain role in heat dissipation, ensuring the normal operation of the cylinder 312.

[0047] In summary, the working process of this sheet material inspection device is as follows: After the suction cup picks up the sheet material and rises 100mm, the cylinder pushes the spherical bearing forward. The connecting shaft connected to the inner ring of the spherical bearing rotates. Since the transmission component connects the connecting shaft to the rotating shaft connected to the fixed base, the rotating shaft also rotates with the connecting shaft. This drives the hanger connected to the other end of the rotating shaft to rotate the inspection piece under the action of the deep groove ball bearing, causing the inspection device to rotate 90 degrees to reach inspection position B. At this time, the sheet material to be tested is exactly in the gap between the transmitter and the receiver. The ultrasonic sensor detects whether multiple sheets of sheet material have been picked up. If a single sheet is detected, the inspection device returns to its original position, and the suction cup continues to rise. If multiple sheets are detected, the inspection device returns to its original position, the suction cup releases the vacuum, and the sheet material falls to the unloading platform. The suction cup then repeats the descent to pick up the sheet material a second time. Conversely, the cylinder moves backward, causing the hanger and inspection piece to rotate 90 degrees in the opposite direction to return to the initial position for the next inspection.

[0048] The above is only one specific implementation of this application, and any other improvements made based on the concept of this application shall be considered within the scope of protection of this application.
