Further, it should be noted that this specification describes many features. Although some features may be combined to show a possible system design, these features may also be used in other combinations not explicitly described.

In the embodiments shown in the drawings, directional references (such as upper, lower, left, right, front and rear) are used to explain the structure and movement of the various elements of the invention not absolutely, but relatively. These descriptions are appropriate when the elements are in the positions shown in the drawings. If the description of the positions of these elements changes, the indication of these directions changes accordingly.

The preferred embodiments of the present invention will be further described in detail with reference to the accompanying drawings.

Referring to fig. 1 to 4, the present invention provides a mounting device 100 capable of detecting material blockage, including: the processing head comprises a body 102, wherein a material guide channel 160 and an inner cavity 150 are arranged in the body 102, the material guide channel 160 extends downwards to the inner cavity 150, and the inner cavity 150 is used for installing the processing head 200.

The material blockage detection assembly is arranged in the material guide channel 160 and deviates from the central axis of the material guide channel 160, and comprises a photoelectric switch 141 and a coded disc 142 which are arranged at intervals relatively, the coded disc 142 is matched with a rotating shaft arranged in the material guide channel 160, a shading part and a light-transmitting part are arranged on the coded disc 142 along the circumferential direction, the photoelectric switch 141 is used for receiving an optical signal reflected by the coded disc 142 and correspondingly generating an electric signal to be output, the photoelectric switch 141 is fixed in the material guide channel 160, and whether material blockage occurs in the material guide channel 160 is judged through the electric signal output by the photoelectric switch 141.

The photoelectric switch 141 emits an optical signal to the code wheel 142, so that, if the light shielding portion of the code wheel 142 is rotated to be opposite to the photoelectric switch 141, the optical signal emitted by the photoelectric switch 141 is reflected by the light shielding portion, and the photoelectric switch 141 receives the optical signal reflected by the light shielding portion; if the light-transmitting portion of the code wheel 142 is rotated to a position opposite to the photo switch 141, the optical signal emitted from the photo switch 141 is transmitted through the light-transmitting portion, and thus the photo switch 141 cannot receive the reflected optical signal or receives a weak reflected optical signal.

An electrical signal, such as a high level signal, is generated when the photo switch 141 receives the reflected light signal, and another electrical signal, such as a low level signal, is generated when the photo switch 141 does not receive the reflected light signal.

In the processing process, the code disc 142 rotates at a constant speed. Thus, if no blockage occurs in the guide passage 160 during the process, the photoelectric switch 141 outputs a periodic electric signal, and the periodic electric signal is periodically switched between a high level and a low level. On the contrary, if a material jam occurs in the material guiding channel 160 during the manufacturing process, the raw material may be stacked in the material guiding channel 160, and the raw material may be stacked in the space between the photoelectric switch 141 and the code wheel 142, or the code wheel 142 may be locked to prevent the code wheel 142 from rotating normally.

If the code wheel 142 is jammed by the material stacked in the material guide passage 160, the code wheel 142 cannot be normal, and at this time, the reflected light signal received by the photoelectric switch 141 is not changed, so that a single signal is continuously output, for example, a high level signal is continuously output, or a low level signal is continuously output.

If materials are stacked between the photoelectric switch 141 and the code wheel 142, the stacked materials may cause the optical signal emitted by the photoelectric switch 141 to be completely reflected by the materials, or the optical signal reflected by the light shielding portion of the code wheel 142 cannot reach the photoelectric switch 141, so that the photoelectric switch 141 outputs an electrical signal different from that when no materials are stacked between the photoelectric switch 141 and the code wheel 142, for example, outputs an irregular electrical signal.

Therefore, whether the material is blocked in the material guiding channel 160 can be judged according to the electric signal output by the photoelectric switch 141, and the processing can be correspondingly carried out. Specifically, if the photoelectric switch 141 outputs a periodic low level signal and a periodic high level switching signal, it is determined that no material blockage occurs in the material guiding channel 160; on the contrary, if the photoelectric switch 141 outputs a single signal or an irregular signal, it is determined that the material guide channel 160 is clogged. By arranging the blockage detection assembly in the material guide channel 160, blockage detection is realized so as to facilitate timely blockage treatment.

Because the central axial setting of putty determine module skew guide passageway to, can avoid putty determine module to block the transmission of material.

In this embodiment, a material guiding wheel 170 is further disposed in the material guiding channel 160, and the material guiding wheel 170 is used for conveying the material in the material guiding channel 160. Specifically, the material guiding wheels 170 are oppositely disposed at two sides of the material guiding channel 160 in the axial direction of the center, so that the material is driven to move to the processing head 200 by the rotation of the material guiding wheels 170 which are oppositely disposed.

In the present embodiment, a guide wheel 170 is provided on the rotary shaft coaxially with the code wheel 142, and only the guide wheel 170 located at the opposite side of the code wheel 142 is shown in fig. 1 to 4, and the guide wheel 170 provided coaxially with the rotary shaft is not shown. Thus, the material guide wheel 170 and the code wheel 142 are simultaneously rotated by driving the rotation shaft.

In the present embodiment, the material guide passage 160 is arranged in a vertical direction and is coaxial with the processing head 200. Therefore, after the raw material enters the material guide channel 160 through the material inlet 161, the raw material can directly enter the processing head 200 along the vertical material guide channel 160 without turning, and the raw material moves downwards by virtue of the gravity of the raw material, so that the raw material can be conveniently conveyed in the material guide channel 160.

In this embodiment, as shown in fig. 1 to 4, the mounting device 100 further includes: an operating member 110 including an operating end 111 and a fixed end 112, the operating end 111 extending out of the body 102, the fixed end 112 rotatably connected to a support shaft 130 fixed in the body 102; the hook member 120 comprises a connecting end 121 and a hook end 122, the connecting end 121 is fixedly connected with the operating end 111, the hook end 122 extends to a notch 151 formed in the side surface of the inner cavity 150, and the operating end 111 is operated to drive the hook member 120 to rotate around the support shaft 130, so that the hook end 122 extends into or withdraws from the inner cavity 150 through the notch 151.

After the tool head 200 is mounted in the interior chamber 150, the tool head 200 is axially secured by the hooked end 122 extending into the interior chamber 150.

In the embodiment, as shown in fig. 1, the operating element 110 is horizontally disposed above the inner cavity 150, the hook member 120 is vertically disposed, the bent end of the hook member 120 is the hook end 122, and the hook end 122 is in a hook shape. Specifically, the hook member 120 is L-shaped.

Since the hook end 122 needs to extend into or withdraw from the inner cavity 150 through the gap 151, the gap 151 is correspondingly formed according to the size of the hook end 122, that is, the size of the gap 151 needs to satisfy the requirement that the hook end 122 extends into or withdraws from the inner cavity 150.

The processing head 200 mounted to the interior chamber 150 is axially secured by the hooked end 122 extending into the interior chamber 150.

It will be appreciated that the hooked end 122 is provided with a mating surface that mates with the end surface of the processing head 200, such that, after the processing head 200 is assembled into the interior cavity 150, the mating surface on the hooked end 122 mates with a corresponding mating surface on the processing head 200 to axially secure the processing head 200 via the hooked end 122.

By arranging the operating member 110 and the hook member 120 to be fixedly connected to the supporting shaft 130, when the operating end 111 applies a force, the operating member 110 rotates around the supporting shaft 130, and drives the hook member 120 to rotate around the supporting shaft 130, so that the hook end 122 of the hook member 120 extends into or exits from the inner cavity 150. Then, after the tool head 200 is assembled into the interior cavity 150, the tool head 200 may be axially secured by the hooked end 122 extending into the interior cavity 150; on the contrary, after the hook end 122 is withdrawn from the inner cavity 150, the processing head 200 can be installed in or removed from the inner cavity 150, so that the processing head 200 can be conveniently fixed and detached from the installation device 100, and the operation is simple and quick.

In the present embodiment, the operation element 110 is located above the inner cavity 150, and the blockage detection assembly is located between the operation element 110 and the inner cavity 150. The guide passage 160 passes through the horizontally disposed operating member 110 and extends to the inner chamber 150.

Further, the inner cavity 150 includes a first shaft hole 152 and a second shaft hole 153, the first shaft hole 152 is located above the second shaft hole 153, an inner diameter of the first shaft hole 152 is smaller than that of the second shaft hole 153, and the notch 151 is disposed on a side surface of the second shaft hole 153.

The first shaft hole 152 is used for radially positioning the processing head 200, and the notch 151 is provided on the side surface of the second shaft hole 153, so that the radial positioning accuracy of the processing head 200 can be prevented from being affected by the notch 151. The second shaft hole 153 is formed at the lower end of the body 102, and the first shaft hole 152 is formed above the second shaft hole 153. Based on the arrangement of the internal cavity 150, the machining head 200 is thus fitted into the internal cavity 150 from the lower end of the body 102.

Fig. 1 shows a schematic diagram of the 3D print head 210 and the mounting device 100, wherein the 3D print head 210 is shown in phantom, and in fig. 1, the hook end 122 extends into the inner cavity to axially fix the 3D print head 210 mounted in the inner cavity. As shown in fig. 2, during the process of pressing the operating end 111 downward, the operating member 110 drives the hook member 120 to rotate around the support shaft 130, so that the hook end 122 exits the inner cavity 150 through the notch 151. At this point, 3D print head 210 may be withdrawn from interior cavity 150. Fig. 3 shows a schematic view of 3D printhead 210 after it exits internal cavity 150.

If the process head 200 is a laser process head 220, the process of withdrawing the laser process head 220 from the interior cavity 150 is similar. Fig. 4 shows a schematic view of the laser processing head 220 in cooperation with the mounting device 100, and the laser processing head 220 is indicated by a dotted line in fig. 4. In fig. 4, the handling end 111 is pressed down so that the hook end 122 now exits the interior cavity 150, the laser processing head 220 may exit directly from the interior cavity 150, or the laser processing head 220 may fit directly into the interior cavity 150 from the outside.

In the present embodiment, the operation end 111 of the operation member 110 extends from the side of the body 102, so that the operation end 111 can be operated by an operator. In other embodiments, the operation end 111 may also extend from the upper end surface of the body 102, and is not particularly limited herein.

In this embodiment, the mounting device 100 further includes a return spring 180, one end of the return spring 180 is fixed in the body 102, and the other end is connected to the operation end 111, and the hook end 122 rotates along the direction extending into the inner cavity 150 during the rotation of the operation end 111 driven by the compressed return spring 180.

Specifically, the return spring 180 is disposed in a vertical direction, a lower end of the return spring 180 is fixed to the body 102, and an upper end of the return spring 180 is connected to the operating end 111, so that the return spring 180 is compressed during a process of rotating the operating element 110 by applying a downward force, and the hook end 122 exits the inner cavity 150 through the gap 151 during the process. If the hook end 122 is required to extend into the inner cavity 150, the operating member 110 can be driven to rotate by the force of the compressed return spring 180, so that the hook end 122 is driven to extend into the inner cavity 150, and an operator does not need to apply a reverse force to the operating end 111, thereby simplifying the operation.

For 3D printing and laser processing, the material conveyed in the material guide channel is a long and thin material. If the material breakage of the elongated material in the material guiding passage 160 is not detected in time, the quality of the product processed by the processing head 200 is directly affected, for example, the material of the product is not uniform.

To solve the problem, in this embodiment, a material breakage detecting contact 190 is further disposed in the material guiding channel 160, wherein the material breakage detecting contact 190 is fixed in the material guiding channel 160 by a spring (not shown in the figure), and when there is no material in the material guiding channel 160, an end of the material breakage detecting contact 190 radially extends into the material guiding channel 160, assuming that the position of the end is the first position at this time. When the material exists in the material guide passage 160, the end of the material breakage detection contact 190 is pressed by the material, and the position of the end of the material breakage detection contact 190 is changed, assuming that the position of the end is the second position at this time.

In the processing process, if the material is not broken, the position of the end of the broken material detection contact 190 is not changed or slightly changed, that is, the end is kept at the second position; and if the material is broken, the position of the end of the material breakage detection contact 190 is changed, namely the end is changed from the second position to the first position. Therefore, it is possible to confirm whether or not the material in the guide passage 160 is broken during the machining process by detecting the change in the position of the end of the breakage detecting contact 190 during the machining process.

The utility model also provides a processing equipment 1000, including processing head 200 and installation device 100 as above, processing head 200 is installed on processing equipment 1000 through installation device 100.

In the present embodiment, as shown in fig. 5, the processing apparatus 1000 includes a base 300, a hanger 400, a mounting device 100, and a processing head 200, and the processing head 200 is mounted and fixedly mounted in the mounting device 100. The base 300 includes a display panel 310 and a table 320 for placing products or materials. The suspension 400 is provided with a horizontal guide rail 410 and a vertical guide rail 420, and the mounting device 100 is mounted on the horizontal guide rail 410.

Thus, lateral movement of the processing head 200 may be achieved by the motor driving the mounting device 100 along the horizontal rail 410. The movement of the processing head 200 in the vertical direction is achieved by the motor driving the horizontal rail 410 to move along the vertical rail 420.

Further, the processing head 200 is a 3D print head 210 or a laser processing head 220. Thus, the processing equipment 1000 can realize 3D printing or laser processing functions, or can realize 3D printing and laser processing functions simultaneously by replacing the processing head 200 as an integrated machine of 3D printing and laser processing.

In programming education, objects with different shapes or patterns are often needed for programming demonstration. In this case, the processing apparatus 1000 of the present embodiment may be used to process a desired object by means of the 3D print head 210 or the laser processing head 220.
