Abstract
Description
Technical Field
[0001] This utility model relates to the field of chemical decoction technology for PCB boards, and in particular to a drum running status detection device and a membrane residue separation device. Background Technology
[0002] In PCB manufacturing, a photosensitive resist layer is first coated onto the copper foil surface. After exposure and development, the circuit pattern is transferred onto the resist layer. Stripping removes the portions of the resist layer not covered by the circuit pattern, exposing the underlying copper foil for subsequent etching. Currently, chemical stripping utilizes a specific chemical solution to react with the resist material, causing it to dissolve or decompose, thus achieving the stripping purpose.
[0003] The chemical solution after membrane stripping contains membrane sludge, which needs to be filtered out using a membrane sludge separation device before the chemical solution is collected for reuse. In existing technology, membrane sludge is recovered by filtering it out using a drum screen, and then the filtered liquid is collected. The drum screen is driven by an electric motor during operation. If the motor unexpectedly stops or other abnormalities cause the drum screen to stop rotating, it will affect the screening of membrane sludge. Utility Model Content
[0004] Therefore, the technical problem to be solved by this utility model is to overcome the defect in the prior art where abnormality in the drive of the membrane residue screening drum affects the screening of membrane residue.
[0005] To solve the above-mentioned technical problems, this utility model provides a drum running status detection device, comprising:
[0006] The rotating part includes a drum body, a drive source, a drive shaft, a support shaft, and a square seat bearing. A drum gear is provided on the outer side of one end of the drum body. The drive shaft and the support shaft are located on both sides of the drum body. A driving gear that meshes with the drum gear is sleeved on the drive shaft. A driven gear that meshes with the drum gear is sleeved on the support shaft. The drive source is located at the end of the drive shaft away from the driving gear. The square seat bearing is located at the end of the support shaft away from the driven gear.
[0007] The detection unit includes a proximity switch and a detection rod. The proximity switch is disposed on one side of the square bearing seat, and the detection rod is connected to the inner ring of the square bearing seat and disposed between the proximity switch and the square bearing seat.
[0008] In one embodiment of this utility model, the inner ring surface of the square bearing seat is provided with a connecting hole, and the detection rod is detachably connected to the connecting hole.
[0009] In one embodiment of this utility model, the axial direction of the detection rod is installed perpendicular to the axial direction of the square bearing seat.
[0010] In one embodiment of the present invention, a support platform is further included, which is disposed at the bottom of the roller body, and a support sleeve that cooperates with the drive shaft is disposed on the support platform.
[0011] In one embodiment of this utility model, support wheels are sleeved on both the drive shaft and the support shaft, and the surface of the support wheel abuts against the two sides of the roller body away from the roller gear.
[0012] In one embodiment of the present invention, a retaining edge is provided on one side of the support wheel, and one end of the roller body abuts against the retaining edge.
[0013] In one embodiment of this utility model, the surfaces of the driving gear and the driven gear are provided with fixing holes, and a limiting bolt that cooperates with the drive shaft and the support shaft passes through the fixing holes.
[0014] In one embodiment of this utility model, a coupling is provided between the drive source and the drive shaft.

[0016] A membrane sludge separation device includes the aforementioned drum operation status detection device.
[0017] The above-mentioned technical solution of this utility model has the following advantages compared with the prior art:
[0018] The present invention relates to a drum operation status detection device and a membrane sludge separation device. In this invention, the square bearing seat rotates synchronously with the drum body. By installing a detection rod on the square bearing seat, the detection rod rotates with the square bearing seat and makes a uniform cutting motion in the proximity switch sensing area.

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention. Example
[0028] Reference Figures 1-6 As shown, this utility model discloses a drum running status detection device, comprising:
[0029] The rotating part 1 includes a roller body 11, a drive source 12, a drive shaft 13, a support shaft 14, and a square bearing 15. A roller gear 111 is provided on the outer side of one end of the roller body 11. The drive shaft 13 and the support shaft 14 are provided on both sides of the roller body 11. A drive gear 131 that meshes with the roller gear 111 is sleeved on the drive shaft 13. A driven gear 141 that meshes with the roller gear 111 is sleeved on the support shaft 14. The drive source 12 is provided at the end of the drive shaft 13 away from the drive gear 131. The square bearing 15 is provided at the end of the support shaft 14 away from the driven gear 141.
[0030] The detection unit 2 includes a proximity switch 22 and a detection rod 21. The proximity switch 22 is disposed on one side of the square bearing 15, and the detection rod 21 is connected to the inner ring of the square bearing 15 and disposed between the proximity switch 22 and the square bearing 15.
[0031] In the rotating part 1 of this invention, the drive shaft 13 and the support shaft 14 are arranged on both sides of the drum body 11. A drive gear 131 is mounted on the drive shaft 13, and a driven gear 141 is mounted on the support shaft 14. Both the drive gear 131 and the driven gear 141 mesh with the drum gear 111 on the surface of the drum body 11. A drive source 12 provides power, driving the drive shaft 13 to rotate. The drive gear 131 drives the drum gear 111, which in turn drives the drum body 11 to rotate. The drum gear 111 then drives the driven gear 141 to rotate, causing the support shaft 14 to rotate synchronously. The detection part 2 consists of a square bearing 15 mounted on the support shaft 14, and a detection rod 21 mounted on the inner ring of the square bearing 15. During the rotation of the support shaft 14, the detection rod 21 rotates synchronously. Secondly, a proximity switch 22 is provided on one side of the square bearing 15. The detection rod 21 will rotate with the square bearing 15 and make a uniform cutting motion in the sensing area of the proximity switch 22. When the drive source 12 that transmits the driving force stops unexpectedly or other abnormalities cause the square bearing 15 to stop running, the proximity switch 22 will not sense the proximity of the detection rod 21 and will send a feedback signal to issue an alarm, thereby achieving the function of warning of abnormality and ensuring the normal operation of the equipment.
[0032] In this invention, the square bearing 15 rotates synchronously with the drum body 11. By installing a detection rod 21 on the square bearing 15, the detection rod 21 rotates with the square bearing 15 and moves at a uniform speed to cut the sensing area of the proximity switch. When the drive source 12 stops unexpectedly or other abnormalities cause the drum body 11 to stop operating, the proximity switch will not sense the proximity of the detection rod 21 and will send a feedback signal to issue an alarm, thereby achieving the function of warning of abnormality and avoiding affecting the screening of membrane residue.
[0033] Furthermore, the inner ring surface of the square bearing 15 is provided with a connecting hole 151, and the detection rod 21 is detachably connected to the connecting hole 151.
[0034] Specifically, the connecting hole 151 on the surface of the square bearing 15 is a threaded hole. Preferably, the detection rod 21 can be a bolt with a corresponding hole diameter, which facilitates connection and disassembly.
[0035] Furthermore, as a preferred embodiment of this utility model, the axial direction of the detection rod 21 is installed perpendicular to the axial direction of the square bearing 15, which can ensure that the area swept by the detection rod 21 during rotation is maximized, thereby improving the detection efficiency of the proximity switch 22.
[0036] Furthermore, it also includes a support platform 3, which is disposed at the bottom of the roller body 11, and a support sleeve 17 that cooperates with the drive shaft 13 is provided on the support platform 3.
[0037] Specifically, the support platform 3 is used to mount the roller body 11, the drive shaft 13, and the support shaft 14, while the support sleeve 17 is used to provide support for the mounting of the drive shaft 13 and the support shaft 14, ensuring the stability of the drive shaft 13 and the support shaft 14. In addition, the support platform 3 is also covered with a housing 4, and the proximity switch 22 is fixed to the housing 4 during the actual installation process.
[0038] Furthermore, both the drive shaft 13 and the support shaft 14 are fitted with support wheels 16, and the surfaces of the support wheels 16 abut against the two sides of the end of the roller body 11 away from the roller gear 111.
[0039] Specifically, one end of the roller body 11 is fixed by the cooperation of the rolling gear on the surface with the driving gear 131 and the driven gear 141, while the other side of the roller body 11 is supported by the support wheel 16 to ensure the stability of the rotation of the entire roller body 11.
[0040] Furthermore, a retaining edge 161 is provided on one side of the support wheel 16, and one end of the roller body 11 abuts against the retaining edge 161. The surfaces of the driving gear 131 and the driven gear 141 are provided with fixing holes 1311, and limiting bolts 1312 that cooperate with the drive shaft 13 and the support shaft 14 are inserted into the fixing holes 1311.
[0041] Specifically, the axial movement of the roller body 11 can be limited by the flange 161 on the surface of the support wheel 16. Similarly, the driving gear 131 and the driven gear 141 can be fixed by the limiting bolt 1312, further restricting the axial movement of the roller body 11 and ensuring the normal rotation of the roller body 11.
[0042] Furthermore, a coupling 18 is provided between the drive source 12 and the drive shaft 13.
[0043] Furthermore, the roller body 11 is tapered along the axial direction.
[0044] Specifically, the drum body 11 generates centrifugal force during rotation, and the drum body 11 is tapered along the axial direction to form a trumpet shape. During rotation, the membrane residue will gradually approach the port at the larger end and eventually fall off the drum body 11 without affecting the subsequent screening of the membrane residue. Example
[0045] A membrane sludge separation device includes the drum operation status detection device described in Example 1.
[0046] A drum operating status detection device and a membrane sludge separation device are disclosed. The square bearing 15 of this invention rotates synchronously with the drum body 11. A detection rod 21 is installed on the square bearing 15. The detection rod 21 rotates with the square bearing 15 and moves at a uniform speed to cut the sensing area of the proximity switch. When the drive source 12 stops unexpectedly or other abnormalities cause the drum body 11 to stop operating, the proximity switch will not sense the proximity of the detection rod 21 and will send a feedback signal to issue an alarm, thereby achieving the function of warning of abnormality and avoiding affecting the screening of membrane sludge.
[0047] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
