Description

Technical Field

[0001] The present technology belongs to the technical field related to PCB equipment, and in particular relates to a motor detection mechanism and PCB pumping equipment. Background Art

[0002] In the electroplating production process of PCB boards, it is necessary to add chemicals to the tank or stir the liquid. However, the pump used for stirring may stop rotating during the stirring process.

[0003] In existing technology, monitoring pumps for proper operation typically relies on listening for noise or manually touching them to identify faults. This method can result in excessive pump volume, making it difficult to quickly and intuitively identify a faulty pump based on sound, leading to substandard and abnormal drug quality. Touching the pump can also pose a risk of electric shock in the event of leakage. Furthermore, since pumps are used to mix corrosive chemicals, touching them can corrode the hand and contaminate the chemicals. Utility Model Content

[0004] In order to solve the above problems, the present invention proposes a motor detection mechanism and a PCB pump device. The device is provided with a detection component on the pump motor. The detection component extends to the outside of the motor and is driven by the motor shaft core. By observing the detection component, a faulty motor can be judged without touching the motor or relying on the sound of the motor.

[0005] The content of this utility model is achieved through the following technical solutions:

[0006] In a first aspect, the present invention provides a motor detection mechanism, comprising:

[0007] The motor comprises a motor body and a shaft core disposed in the motor body, wherein the shaft core rotates when driven by the motor body;

[0008] The protective housing is fixed to the motor body and is arranged on the outer peripheral side of the shaft core; the protective housing is provided with a mounting hole, and the mounting hole and the shaft core are located on the same axis;

[0009] And a detection component, including a first connecting member and a first detecting member, one end of the first connecting member is connected to the shaft core through the mounting hole, and the other end of the first connecting member is connected to the first detecting member to detect the driving state of the motor.

[0010] The motor includes a motor body and a shaft core disposed within the motor body, the shaft core rotating under the drive of the motor body; a protective housing fixed to the motor body, the protective housing disposed on the outer periphery of the shaft core; a mounting hole provided in the protective housing, the mounting hole and the shaft core being coaxially located; and a detection assembly including a first connecting member and a first detecting member, one end of the first connecting member passing through the mounting hole and connected to the shaft core, and the other end of the first connecting member connected to the first detecting member, for detecting the driving status of the motor. By providing the detection assembly and the driving connection between the detection assembly and the motor shaft core, it is possible to determine whether the pump is faulty by detecting the driving status of the detection assembly, thereby avoiding manual touch and auditory judgment.

[0011] In some embodiments, the first connecting member is an insulating portion, and the protective shell is made of an insulating material.

[0012] In order to further improve the insulation effect, the first connecting member is set as an insulator and the protective shell is made of insulating material, so that the parts outside the motor are all insulating structures to prevent external electric shock caused by leakage.

[0013] In some embodiments, the middle portion of the first connecting member is solid, or a through hole is provided in the first connecting member, and the portion of the first connecting member disposed within the protective shell is provided with a connecting hole, and the power cord can extend into the through hole through the connecting hole and extend from the through hole to the outside to be electrically connected to the first detection member.

[0014] The middle portion of the first connecting member is solid, or is non-solid and provided with a through hole, so that the wire can extend from the inside of the motor through the through hole to be connected to the first detecting member.

[0015] In some embodiments, the first connecting member and the first detecting member may be integrally formed, or the first connecting member and the first detecting member may be detachably provided as separate parts.

[0016] The first connecting member can be integrally formed with the first detecting member. The advantage of this method is that it can reduce the complexity of the detecting assembly. It can also be detachable to prevent the first detecting member or the first connecting member itself from having problems, which may cause incorrect detection results.

[0017] In some embodiments, the length of the first connecting member from the mounting hole to the first detecting member is 3 to 5 cm.

[0018] By providing the first connecting member with a certain length, the first detecting member on the first connecting member is prevented from touching the motor during operation.

[0019] In some embodiments, the diameter of the mounting hole is 3-5 mm.

[0020] The mounting hole diameter is larger than the diameter of the first connecting member so that the first connecting member can be installed, while also preventing the liquid from splashing into the interior of the protective shell during stirring due to the excessive size.

[0021] In some embodiments, the first detection component is a fan.

[0022] Preferably, the first detection component is a fan, which reduces the complexity of the detection component and also reduces the cost.

[0023] In some embodiments, a cooling fan is provided inside the protective shell, the cooling fan is provided on the shaft core and rotates through the shaft core; and the protective shell is provided with cooling holes, and the cooling hole ring is provided on the side around the mounting hole.

[0024] A cooling fan is arranged in the protective shell, and the cooling fan also rotates with the shaft core, providing heat dissipation for the motor while avoiding the need to add multiple motor-driven cooling fans.

[0025] In some embodiments, the motor body is provided with a wiring harness box.

[0026] The motor is electrically connected to an external power supply device through the wiring harness box. At the same time, in some optional ways, power can be provided for the first detection component.

[0027] In the second aspect, the utility model proposes a PCB pumping device, including a motor detection mechanism, a monitoring mechanism, and an alarm mechanism as proposed in the first aspect; the monitoring mechanism determines the normal operation of the pumping device by monitoring the operation of the detection component, and when the detection component is in a stagnant state, the alarm mechanism sends an alarm signal to the outside.

[0028] By installing a click detection mechanism on the pump and a monitoring mechanism at the same time, the equipment can be equipped with the function of non-manual monitoring of pump operation, improving the degree of automation and being more timely than manual monitoring. At the same time, an alarm mechanism is provided to send an alarm signal when a faulty pump stops.

[0029] The beneficial effects of the motor detection mechanism and PCB pumping equipment of the utility model are:

[0030] The motor includes a motor body and a shaft core disposed within the motor body, the shaft core rotating under the drive of the motor body; a protective housing fixed to the motor body, the protective housing disposed on the outer periphery of the shaft core; a mounting hole provided in the protective housing, the mounting hole and the shaft core being coaxially located; and a detection assembly including a first connecting member and a first detecting member, one end of the first connecting member passing through the mounting hole and connected to the shaft core, and the other end of the first connecting member connected to the first detecting member, for detecting the driving status of the motor.

[0047] Example 1:

[0048] like Figure 1 As shown, the utility model proposes a motor detection mechanism, comprising:

[0049] The motor includes a motor body 100 and a shaft core disposed in the motor body 100, and the shaft core rotates under the drive of the motor body 100;

[0050] The protective housing 200 is fixed to the motor body 100 and is disposed on the outer periphery of the shaft core. The protective housing 200 is provided with a mounting hole, and the mounting hole and the shaft core are located on the same axis.

[0051] And the detection component 300 includes a first connecting member 310 and a first detecting member, one end of the first connecting member 310 is connected to the shaft core through the mounting hole, and the other end of the first connecting member 310 is connected to the first detecting member to detect the driving state of the motor.

[0052] Specifically, the motor body 100 is provided with a shaft core. When the pump is operating normally, the shaft core rotates under the drive of the motor body 100. By setting a protective shell 200 on the outside of the motor body 100, the protective shell 200 can be fixed to the motor body 100 by welding or screws, or it can be set on the outside of the motor body 100 in an integrated manner when it is set. The protective shell 200 is set on the outer peripheral side of the shaft core, and when it is set, the mounting hole of the protective shell 200 is set opposite the shaft core. The protective shell 200 is set at a certain height so that the mounting hole is set away from the motor mounting surface to reduce the impact of the protective shell 200 on the motor body 100 during vibration. A detection component 300 is also provided. The detection component 300 includes a first connecting member 310 for connection and a first detection member for detection. The first detecting member can be connected to the shaft core by being welded to the shaft core through the first connecting member 310, and can also be electrically connected to the motor body 100 through the first connecting member 310, so that when the motor body 100 is driven normally, the first detecting member is driven. The driving includes mechanical driving, which may include conventional mechanical movements such as rotation, movement, and twisting, and electrical driving, which may include electrical connections, such as turning lights on and off, lighting sensors, etc., so that by observing the driving of the first detecting member, it is possible to judge whether the shaft core is operating normally, and then to judge whether the motor body 100 is operating normally.

[0053] The beneficial effect of this approach is that by providing the detection assembly 300 and the driving connection between the detection assembly 300 and the shaft core of the motor body 100, the driving status of the detection assembly 300 can be used to determine whether the pump is faulty, eliminating the need for manual touch and auditory judgment. At the same time, the detection assembly 300 is driven simultaneously with the shaft core, eliminating the need for an additional drive source to drive the detection assembly 300. Furthermore, the detection assembly 300 is relatively simple, reducing the complexity of the equipment and lowering the equipment cost.

[0054] Example 2:

[0055] like Figures 2 and 3 As shown, this embodiment is based on Example 1 and further optimizes and explains some of the structures mentioned in Example 1.

[0056] In some embodiments, the first connecting member 310 is an insulating portion, and the protective housing 200 is made of an insulating material.

[0057] Specifically, the first connector 310 is made of an insulating material, which can be an elastic insulating material or a non-elastic insulating material. It should be noted that when the elastic insulating material is used, it is necessary to ensure that the first connector 310 does not bend when it is installed. Common insulating materials such as rubber strips can be used as the material to reduce the cost of producing the first connector 310. To further enhance insulation performance, a protective housing 200 is also provided, and the protective housing 200 is also made of an insulating material.

[0058] The beneficial effect of this embodiment is that the first connecting member 310 is set as an insulator, and the protective shell 200 is made of insulating material, so that the parts outside the motor body 100 are all insulating structures to prevent external electric shock caused by leakage.

[0059] In some embodiments, the middle portion of the first connecting member 310 is solid, or a through hole is provided in the first connecting member 310, and the portion of the first connecting member 310 provided in the protective shell 200 is provided with a connecting hole, and the power cord can be extended into the through hole through the connecting hole, and extended from the through hole to the outside to be electrically connected to the first detection member.

[0060] Specifically, the middle portion of the first connecting member 310 can be set to be solid to improve the overall hardness and prevent the first connecting member 310 from bending during operation. This method is suitable for a mechanically driven first detection member. A solid first connecting member 310 can be used when the rotational energy of the shaft core is transmitted only through the first connecting member 310. When the first detection member is electrically driven, a through hole can be set in the middle of the first connecting member 310, and a connecting hole can be set in the part near the inside of the first connecting member 310, so that the first connecting member 310 can pass an electric wire through the connecting hole and be electrically connected to the first detection member, such as a light module or a sensor module for power supply. When a through hole is set in the middle, the material strength of the first connecting member 310 is stronger to ensure that the first connecting member 310 will not bend during movement.

[0061] The beneficial effect of this method is that the middle part of the first connecting member 310 is solid, or is set to be non-solid and provided with a through hole, so that the wire can extend from the inside of the motor body 100 through the through hole to the first detection member for connection.

[0062] In some embodiments, the first connecting member 310 and the first detecting member may be integrally formed, or the first connecting member 310 and the first detecting member may be detachably formed as separate parts.

[0063] Specifically, the first connecting member 310 and the first detecting member can be integrally formed and set, and the first connecting member 310 and the first detecting member can be integrally formed by injection molding. The first connecting member 310 and the first detecting member can be separable and detachable. Specifically, a thread can be set on the first connecting member 310, and a screw hole can be set in the middle of the second detecting member 320, which is installed through the threaded screw hole and fixed with a nut. A snap-on structure can also be adopted, such as setting a snap-on step on the first connecting member 310, setting an elastic snap-on on the first detecting member, snapping it onto the snap-on step through the elastic snap-on, and deforming the elastic snap-on to disengage from the snap-on step to achieve detachable installation of the first connecting member 310 and the first detecting member. The beneficial effect of this method is that the first connecting member 310 can be integrally formed with the first detecting member. The advantage of this method is that it can reduce the complexity of the detection component 300. It can also be detachably set to prevent the first detecting member or the first connecting member 310 itself from having problems, which may cause incorrect detection results.

[0064] In some embodiments, the length of the first connecting member 310 from the mounting hole to the first detecting member is 3 to 5 cm.

[0065] Specifically, the length of the first connecting member 310 from the mounting hole to the first detection member is set to 3.5 cm. This length ensures that the first detection member does not touch the protective housing 200 during rotation. At the same time, it also ensures that the first connecting member 310 is not too long, causing the first connecting member 310 to bend during rotation. At the same time, this length also ensures that there is a certain amount of contact space for the first detection member when in use, so that if it is unclear whether it has been rotated, it can be determined by touching the first connecting member 310.

[0066] The beneficial effect of this approach is that, by providing the first connecting member 310 with a certain length, the first detecting member on the first connecting member 310 is prevented from touching the motor body 100 during operation.

[0067] In some embodiments, the diameter of the mounting hole is 3-5 mm.

[0068] Specifically, the diameter of the mounting hole is set at 3.5 mm to match the diameter of the first connecting member 310, which is usually 3 mm, so that the first connecting member 310 can pass through the diameter of the mounting hole.

[0069] The mounting hole diameter is larger than the diameter of the first connecting member 310 so that the first connecting member 310 can be installed, while also preventing the liquid from splashing into the interior of the protective housing 200 during stirring due to the excessive size.

[0070] In some embodiments, the first detection component is a fan.

[0071] Specifically, the middle part of the fan is arranged on the first connecting member 310, and the first connecting member 310 is driven to rotate by the shaft core, thereby realizing the rotation of the fan. By observing whether the fan rotates, it is determined whether the pump surge is operating normally.

[0072] Preferably, the first detection component is a fan, which reduces the complexity of the detection component 300 and also reduces the cost.

[0073] In some embodiments, a cooling fan 400 is provided inside the protective shell 200 , and the cooling fan 400 is provided on the shaft core and rotated by the shaft core; and the protective shell 200 is provided with cooling holes 410 , and the cooling holes 410 are arranged around the mounting hole.

[0074] Specifically, a heat dissipation fan 400 is provided in the protective shell 200 . The heat dissipation fan 400 can be provided as one or more fans, which are provided in the protective shell 200 and driven by the shaft core. A plurality of heat dissipation holes 410 are provided to discharge heat through the heat dissipation holes 410 .

[0075] The beneficial effect of this method is that a cooling fan 400 is set in the protective shell 200, and the cooling fan 400 also rotates with the shaft core, providing heat dissipation for the motor body 100 while avoiding adding multiple motor bodies 100 to drive the cooling fan 400.

[0076] In some embodiments, the motor body 100 is provided with a wiring harness box.

[0077] Specifically, the wiring harness box is set on one side of the motor body 100, and is connected to an external power supply through the wiring harness box. At the same time, when the first detection component is electrically driven, the driving wire can be introduced from the wiring harness box into the first connecting component 310 and electrically connected to the first detection component.

[0078] This method has the beneficial effect of electrically connecting the motor body 100 to an external power supply device through the wiring harness box. At the same time, in some optional methods, power can be provided to the first detection member.

[0079] Example 3:

[0080] like Figure 4 As shown, this embodiment, based on Example 1 and Example 2, proposes a PCB pumping device, including the motor detection mechanism, monitoring mechanism, and alarm mechanism proposed in the first aspect; the monitoring mechanism determines the normal operation of the pumping device by monitoring the operation of the detection component 300, and when the detection component 300 is in a stagnant state, the alarm mechanism sends an alarm signal to the outside.

[0081] Specifically, when multiple pump surge devices are provided, a monitoring mechanism is provided for each motor detection mechanism. The monitoring mechanism can be a sensor module, such as a CCD, a camera, an infrared sensor, or an optical sensor. The monitoring mechanism is provided outside the motor detection mechanism to monitor the operation of the motor body 100, such as by determining whether the first detection element is actuated using a CCD, or by monitoring whether the first detection element is actuated using an infrared sensor. An alarm mechanism is also provided, connected to the monitoring mechanism, and transmits an alarm signal when the monitoring mechanism detects that a first detection element is not actuated.

[0082] The beneficial effect of this embodiment is that by providing a click detection mechanism on the pump and a monitoring mechanism at the same time, the equipment can be equipped with the function of non-manual monitoring of pump operation, improving the degree of automation and being more timely than manual monitoring. At the same time, an alarm mechanism is provided, which sends an alarm signal when it detects that the pump has stopped operating due to a fault.
