Technical Field
The utility model relates to an equipment warning technical field especially relates to an alarm mechanism and vacuum etching machine spray set drop.
Background
To realize the functional cooperation between equipment, the connecting part is essential, for example: a pipe or a wire, wherein the stability of the connection of the connecting part to the device directly determines the operational stability of the function between the devices. However, the connecting parts on some devices are easy to fall off from the devices, and after the connecting parts fall off, operators cannot find the connecting parts timely and accurately, so that a series of subsequent accidents are easily caused.
For example, in the current PCB vacuum etching machine, the spray pump is connected to the spray header through the spray hose, and the connection between the spray hose and the spray header mainly adopts a screw thread screwing manner. The specific installation mode is as follows: the spray hose is inserted into the spray head interface and screwed by hand.

Because the trigger piece moves and can trigger the switch assembly to be in the closed state, when the trigger piece drops along with the connecting part and moves, the switch assembly is in the closed state, so that a circuit where the alarm is located is in the conducting state, and the alarm works and gives an alarm. Therefore, the operating personnel can timely and accurately find the falling problem of the connecting part and timely take corresponding measures to maintain so as to prevent the product from being continuously produced under the condition that the connecting part falls off and further to cause the product to be scrapped in batches. Meanwhile, the connecting part is indirectly matched with the alarm structure through the fixing part and the trigger part, and the condition that the alarm structure needs to directly operate on the connecting part to cause the assembly operation of the falling alarm mechanism to be completed in a limited space is avoided. In addition, the fixing piece and the triggering piece replace a connecting part to trigger the alarm to work, so that the alarm is more timely and has higher alarm precision, and the phenomenon that the alarm cannot be triggered to work because the connecting part still acts on the alarm structure after falling off is avoided.

In one embodiment, referring to fig. 1 and 2, a drop-off alarm mechanism 100 includes: a fixed member 110, a triggering member 120 and an alarm structure 130. The fixing member 110 is for being mounted on the connection member 200. The triggering member 120 is drivingly connected to the fixing member 110. Alarm structure 130 includes alarm 132 and with alarm 132 electric connection's switch module 131, switch module 131 triggers the cooperation with trigger 120, and trigger 120 removes and is used for making switch module 131 be in the closure state.
In the drop alarm mechanism 100, the fixing member 110 is mounted on the connecting member 200; then, the triggering member 120 is in transmission fit with the fixing member 110, so that the triggering member 120 moves along with the movement of the fixing member 110, and thus, when the connecting member 200 falls off, the connecting member 200 drives the triggering member 120 to move through the fixing member 110. Since the trigger 120 moves to trigger the switch assembly 131 to be in the closed state, when the trigger 120 moves along with the dropping of the connecting component 200, the switch assembly 131 is in the closed state, so that the circuit where the alarm 132 is located is in the conducting state, and the alarm 132 operates to alarm. Therefore, the operator can timely and accurately find the falling problem of the connecting part 200 and timely take corresponding measures to maintain the connecting part to prevent the product from being continuously produced under the condition that the connecting part 200 falls off, so that the product is scrapped in batches. Meanwhile, in the embodiment, the fixing element 110 and the triggering element 120 are used to indirectly cooperate the connecting element 200 with the alarm structure 130, so that the situation that the alarm structure 130 needs to directly operate on the connecting element 200 to cause the assembly operation of the drop alarm mechanism 100 to be completed in a limited space is avoided, and thus, the assembly of the drop alarm mechanism 100 is more convenient, which is beneficial to improving the assembly efficiency of the drop alarm mechanism 100. In addition, the fixing part 110 and the triggering part 120 replace the connecting part 200 to trigger the alarm 132 to work, so that the alarm is timely and high in alarm precision, and the situation that the alarm 132 cannot be triggered to work because the connecting part 200 still acts on the alarm structure 130 after falling off is avoided.
It should be noted that the closed state of the present embodiment is understood that the switch assembly 131 is in the on state, so that the circuit of the alarm 132 is in the on state, that is, the alarm 132 is connected to the power source 133, and at this time, the alarm 132 can operate to alarm.
Alternatively, the fixing member 110 may be mounted on the connecting member 200 by bolting, welding, bonding, binding, sleeving, or other mounting means. Meanwhile, the driving connection between the triggering member 120 and the fixing member 110 may also be realized by bolts, welding, bonding, binding or other connection methods. Wherein, the fixing member 110 is a supporting rod structure or a lantern ring structure; the connecting member 200 is a pipe or a wire; the trigger 120 is a latch or catch arrangement.
Specifically, the alarm 132 of the present embodiment is a buzzer, wherein the switch component 131 is a disconnection and contact connection structure between the conductive components; or a light conducting and light disconnecting structure between the light generator and the light receiver.

The trigger component 120 is located between the first conductive component 1311 and the second conductive component 1312, and the first conductive component 1311 and the second conductive component 1312 are insulated and separated by the trigger component 120, and the driving component 1313 is used for driving the first conductive component 1311 and the second conductive component 1312 to be in contact. As can be seen, when the connection member 200 is not detached, the triggering member 120 separates the first conductive member 1311 from the second conductive member 1312, so that the switch assembly 131 is in an open state; when the connecting member 200 falls off, the triggering member 120 moves to separate from the first conductive member 1311 and the second conductive member 1312, and at this time, the first conductive member 1311 and the second conductive member 1312 approach and contact each other under the action of the driving member 1313, so that the switch assembly 131 is in a closed state, and an alarm 132 is triggered to operate. Specifically, in the present embodiment, the trigger 120 is an insulating plug structure.
Alternatively, the driving element 1313 may be an elastic element or a magnet, when the driving element 1313 is a magnet, the first conductive element 1311 and the second conductive element 1312 are both provided with magnets, and when the triggering element 120 moves away from between the first conductive element 1311 and the second conductive element 1312, the first conductive element 1311 and the second conductive element 1312 are attracted to each other by the magnets to make contact. The first conductive member 1311 and the second conductive member 1312 are each a copper sheet, an aluminum sheet, an iron sheet, a carbon rod, or other conductive materials.
Further, referring to FIG. 2, the alarm structure 130 further includes a support 134. The driving member 1313 is an elastic member. The first conductive member 1311 is disposed on the support 134 by an elastic member. When the triggering member 120 moves away from between the first conductive member 1311 and the second conductive member 1312, the first conductive member 1311 contacts the second conductive member 1312 by the elastic member. In this way, the elastic member is used to drive the first conductive member 1311 to move, and the first conductive member 1311 is in contact with the second conductive member 1312, so that the alarm operates and gives an alarm. Wherein, the elastic element can be a spring or elastic rubber.
In one embodiment, referring to fig. 2, the support 134 includes a bottom plate 1341 and a support plate 1342 disposed on the bottom plate 1341. The first conductive member 1311, the second conductive member 1312 and the alarm 132 are disposed on the bottom plate 1341, and the first conductive member 1311 is disposed on the supporting plate 1342 through an elastic member. In this way, the elastic member is stabilized against the first conductive member 1311 by the supporting plate 1342.
Further, a first guide portion (not shown) is provided on the bottom plate 1341. The first conductive member 1311 is provided with a second guiding portion (not shown) which is guided and matched with the first guiding portion, so that the first conductive member 1311 can move on the bottom plate 1341 more stably, thereby ensuring that the first conductive member 1311 and the second conductive member 1312 are accurately contacted.
Optionally, the first guide part is a guide bar, and the second guide part is a guide groove; or the first guide part is a guide groove, and the second guide part is a guide strip.
In one embodiment, referring to fig. 2 and 3, the bottom plate 1341 is provided with a first guiding hole 1343. The triggering member 120 penetrates into the first guide hole 1343 and is located between the first conductive member 1311 and the second conductive member 1312. Thus, the moving track of the triggering member 120 is effectively guided by the first guiding hole 1343, so as to prevent the triggering member from moving between the first conductive member 1311 and the second conductive member 1312 when moving.
Further, referring to fig. 2, the falling-off alarm mechanism 100 further includes a cover 135. The cover 135 covers the support 134, and a second guide hole 1351 is formed in the cover 135 to be opposite to the first guide hole 1343. In this way, the moving track of the trigger 120 is further corrected.

Further, referring to fig. 2, the falling off alarm mechanism 100 further includes a guiding member 136. Guide 136 is disposed on seat 134. The spring is sleeved within the guide 136. Therefore, the compression or expansion of the spring is performed in the guiding element 136, so that the spring is ensured to stably push the first conductive element 1311 to move, and the first conductive element 1311 is prevented from deflecting on the bottom plate 1341 due to the deflection of the spring. In this embodiment, the guide 136 is a tubular structure.
In one embodiment, referring to fig. 1, the fixing member 110 is a pipe clamp. The pipe clamp is used to clamp onto the attachment member 200. In this way, the fixing member 110 is designed as a pipe clamp, which facilitates the quick installation of the fixing member 110 on the connecting member 200, thereby facilitating the improvement of the installation efficiency of the drop alarm mechanism 100.
In one embodiment, referring to fig. 2 and 4, the alarm structure 130 further includes a power source 133. The power source 133, the switch module 131, and the alarm 132 are connected in series. Therefore, the alarm structure 130 of the present embodiment is a built-in power supply 133 structure, and the power supply 133 provides a stable power supply 133 for the alarm 132.
In one embodiment, referring to fig. 1 and fig. 2, a spray device of a vacuum etching machine includes a spray pipe and the falling-off alarm mechanism 100 of any of the above embodiments, and a fixing member 110 is fixed on the spray pipe.
In the spraying device of the vacuum etching machine, the falling-off alarm mechanism 100 is adopted, and the fixing piece 110 is arranged on the spraying pipe; then, the trigger 120 is in transmission fit with the fixing member 110, so that the trigger 120 moves along with the fixing member 110, and thus, when the shower pipe falls off, the shower pipe drives the trigger 120 to move through the fixing member 110.
