Description

Technical Field

[0001] The invention relates to the technical field of tin stripping, and in particular to a fully automatic spray-type tin stripping device. Background Art

[0002] Tin stripping is one of the important processes in the production of printed circuit boards. Tin plating, tin-lead alloy plating and tin soldering points are stripped by tin stripping solvents. Tin stripping devices are used for electronic components. The tin / lead-tin alloy layer on the copper surface is stripped during the manufacturing process of circuit boards. It can be operated by immersion or mechanical spraying.

[0003] Most existing detinning devices require manual shaking of the products to be detinned, so that the detinned products can be more fully exposed to the detinning solution. However, during the large amount of labor, operators will become fatigued, which will lead to a decrease in the progress of the detinning work.

[0004] Therefore, it is necessary to design a fully automatic spray-type tin stripping device to address the above problems. Summary of the invention

[0007] Furthermore, the discharge assembly includes a connecting plate, a tension spring and a cloth bag. The left and right sides of the lower end of the connecting plate are provided with tension springs, and the middle part of the lower end of the connecting plate is connected to the cloth bag.

[0008] Furthermore, the toggle assembly includes a motor and a toggle rod, and the lower end of the motor is connected to the toggle rod.

[0009] Furthermore, a waste liquid collection assembly is provided in the middle of the upper end of the bottom support plate, and side clamping blocks are provided at both left and right ends of the waste liquid collection assembly. The waste liquid collection assembly includes a collection box and a rolling wheel, and the lower end of the collection box is connected to the rolling wheel.

[0010] Furthermore, a solution storage box is connected to the right side of the upper end of the bottom support plate, and a liquid inlet pipe is installed inside the right wall of the solution storage box.

[0011] Furthermore, a contact block is connected to the upper end of the solution storage box, and a buzzer is connected to the upper end of the contact block. A buoyancy push rod penetrates the left side of the upper wall of the solution storage box.

[0012] Furthermore, a liquid suction tube pump passes through the middle of the upper wall of the solution storage tank, and the upper end of the liquid suction tube pump is connected to a spray assembly, the spray assembly includes a spray pipe and a hand ring, the upper end of the spray pipe is connected to a hand ring, and the front and rear ends of the spray pipe are provided with snap-on assemblies.

[0013] Furthermore, the clamping assembly includes a clamping block 1 and a supporting spring, and the inner side of the clamping block 1 is connected to the supporting spring, and the outer side of the clamping block 1 is connected to the locking assembly.

[0014] Furthermore, the locking assembly includes a locking buckle, a shallow groove and a through groove. The upper ends of the front and rear walls of the locking buckle are provided with a shallow groove, and the lower ends of the front and rear walls of the locking buckle are provided with a through groove.

[0015] Furthermore, the left end of the support rod is connected to a standing component, and the standing component includes a bracket, a grooved side panel, a second clamping block and a buffer pad. The left and right ends of the bracket are provided with grooved side panels, the upper end of the bracket is connected to a buffer pad, and the lower end of the bracket is connected to a second clamping block.

[0016] Compared with the prior art, the beneficial effects of the present invention are: the connection shaking of the discharge component and the toggle component increases the contact area between the detinning parts and the solution, thereby increasing the detinning effect; the setting of the rolling wheel and the side clamping block facilitates the fixed removal of the collection box and improves work efficiency; the coordinated use of the buoyancy push rod and the buzzer prevents the solution from affecting the spraying; the clamping setting of the clamping component and the locking component can cooperate with the hand ring to obtain both fixed and hand-held spraying modes, thereby improving the practicability of the equipment; the stackable design of the standing component facilitates the adjustment of the height of the operating table, thereby improving the applicability of the equipment.

[0017] 1. When the detinning parts are loaded and transported by the present invention, the operator first places the parts inside the cloth bag, and then slides the hook and fixes it so that it can be hung on the hook for fixation, and then drives the cloth bag to move to the right through the sliding block to facilitate spraying by the spray pipe. During the spraying process, all-round spraying can be carried out by rotating the rotating shaft, and then the tension spring acts on the cloth bag to shake and pull it, which can increase the shaking frequency of the cloth bag, and then the toggle rod is driven to rotate by the motor to further improve the shaking effect of the cloth bag. In this way, the contact area between the detinning parts and the solution is increased, thereby increasing the detinning effect.

[0018] 2. The collecting box of the present invention is placed below the cloth bag, so that the solution dripping from the spray can be collected inside the collecting box. When installing the collecting box, the collecting box is pushed, and the rolling wheels are used to reduce the sliding friction, making it easier to save effort. The left and right ends of the collecting box can be clamped and fixed through the side clamping blocks. This setting can facilitate the fixing, removal, pouring out and replacement of the collecting box, improving work efficiency.

[0019] 3. During the spraying process of the present invention, the solution inside the solution storage box is pumped through the liquid suction pipe pump for spraying. As the liquid level drops, it will drive the buoyancy push rod to move downward, and then the buoyancy push rod touches the contact block to turn on the switch of the buzzer, so as to remind the operator to turn on the switch of the liquid inlet pipe to supplement the tin stripping solution. This setting can timely supplement the tin stripping solution and avoid the influence of insufficient solution on the spraying efficiency of the equipment.

[0020] 4. During the spraying process of the present invention, the tin stripping solution is sprayed through the spray pipe. The handle ring at the upper end of the spray pipe can be manually held, which is convenient for spraying some parts that are not easy to spray under certain special circumstances. When the spray pipe needs to be fixed, the spray pipe is pressed inside the locking buckle. Then the clamping block one first slides through the shallow groove and is convenient to move under the extrusion of the support spring. When passing through the through groove, the elastic force of the support spring forces the clamping block one to be stuck inside the through groove for fixation. When it needs to be taken out, an iron rod needs to be inserted into the through groove externally to squeeze the clamping block one, and then it can be pulled out. Through this setting, two spraying methods of fixation and manual holding can be obtained, improving the practicability of the equipment.

[0021] 5. During the use of the present invention, the only manual operations required are the hanging and taking of the hook and the moving hanging buckle. To facilitate the operation of operators of different heights, a support table is set up with a bracket and a buffer pad. Then, when it needs to be raised, a set of standing components is taken out, and the clamping block two is inserted into the grooved side plate of the previous component. Then the buffer pad protects and stabilizes the lower end of the bracket. Through this setting, it is convenient to adjust the height of the operation table, thereby improving the applicability of the equipment. Description of the Drawings

[0029] like Figure 1 and Figure 2 As shown, the present invention provides a technical solution: a fully automatic spray-type tin stripping device, comprising a bottom support plate 1 and a material discharge assembly 7, a support rod 2 is arranged on the left side of the upper end of the bottom support plate 1, and the Shandong crown of the support rod 2 is connected to a sliding track 3, a mobile rotating assembly 4 is connected to the left side of the lower end of the sliding track 3, and the mobile rotating assembly 4 comprises a sliding block 401 and a rotating shaft 402, the interior of the sliding block 401 is connected to the rotating shaft 402, and hooks 5 are arranged on both the left and right ends of the sliding block 401. , the lower end of the hook 5 is connected with a mobile hook 6, the discharge assembly 7 is connected to the lower end of the mobile hook 6, the right end of the sliding track 3 is installed with a toggle assembly 8, the discharge assembly 7 includes a connecting plate 701, a tension spring 702 and a cloth bag 703, the left and right sides of the lower end of the connecting plate 701 are provided with tension springs 702, and the middle part of the lower end of the connecting plate 701 is connected with a cloth bag 703, the toggle assembly 8 includes a motor 801 and a toggle rod 802, and the lower end of the motor 801 is connected with the toggle rod 802;

[0030] The specific operation is as follows. The operator first places the parts inside the cloth bag 703, then slides and fixes the moving hanging buckle 6 so that it can be hung on the hanging hook 5 for fixation. Then, the slider 401 drives the cloth bag 703 to move to the right, facilitating spraying by the spray pipe 1701. During the spraying process, the rotating shaft 402 rotates to perform omnidirectional spraying. Then, the stretching spring 702 acts on the cloth bag 703 to shake and pull it, which can increase the shaking frequency of the cloth bag 703. Then, the motor 801 drives the dial rod 802 to rotate, further improving the shaking effect of the cloth bag 703.

[0031] As Figure 1 shown, a waste liquid collection component 9 is provided in the middle of the upper end of the bottom support plate 1, and side clamping blocks 10 are provided at both the left and right ends of the waste liquid collection component 9. The waste liquid collection component 9 includes a collection box 901 and rolling wheels 902, and the rolling wheels 902 are connected to the lower end of the collection box 901;

[0032] The specific operation is as follows. The operator places the collection box 901 below the cloth bag 703, so that the solution dripping from the spraying can be collected inside the collection box 901. When installing the collection box 901, by pushing the collection box 901, the rolling wheels 902 reduce the sliding friction, facilitating labor saving, and the side clamping blocks 10 can clamp and fix both the left and right ends of the collection box 901.

[0033] As Figure 1 and Figure 3 shown, a solution storage box 11 is connected to the upper right end of the bottom support plate 1, and a liquid inlet pipe 12 is installed inside the right wall of the solution storage box 11. A contact block 13 is connected to the upper end of the solution storage box 11, and a buzzer 16 is connected to the upper end of the contact block 13. A buoyancy push rod 14 penetrates through the left side of the upper wall of the solution storage box 11;

[0034] The specific operation is as follows. During the spraying process, the solution inside the solution storage box 11 is pumped for spraying through the liquid extraction pipe pump 15. As the liquid level drops, it will drive the buoyancy push rod 14 to move downward. Then, the buoyancy push rod 14 touches the contact block 13, turning on the switch of the buzzer 16 to remind the operator to turn on the switch of the liquid inlet pipe 12 to supplement the tin stripping solution.

[0035] As Figure 1 、 Figure 4 and Figure 5As shown, a liquid extraction pipe pump 15 penetrates through the middle of the upper wall of the solution storage tank 11, and the upper end of the liquid extraction pipe pump 15 is connected to a spraying assembly 17. The spraying assembly 17 includes a spraying pipe 1701 and a hand-held ring 1702. The upper end of the spraying pipe 1701 is connected to the hand-held ring 1702, and clamping assemblies 18 are arranged at both the front and rear ends of the spraying pipe 1701. The clamping assembly 18 includes a first clamping block 1801 and a support spring 1802, and the inner side of the first clamping block 1801 is connected to the support spring 1802. The outer side of the first clamping block 1801 is connected to a locking assembly 19. The locking assembly 19 includes a locking buckle 1901, a shallow groove 1902, and a through groove 1903. Shallow grooves 1902 are opened at the upper ends of the front and rear inner walls of the locking buckle 1901, and through grooves 1903 are opened at the lower ends of the front and rear inner walls of the locking buckle 1901;

[0036] The specific operation is as follows. During the spraying process, the desoldering solution is sprayed through the spraying pipe 1701. Then, the hand-held ring 1702 at the upper end of the spraying pipe 1701 can be manually held, which is convenient for spraying some parts that are not easy to spray in certain special situations. When the spraying pipe 1701 needs to be fixed, it is pressed inside the locking buckle 1901 through the spraying pipe 1701. Then, the first clamping block 1801 will first slide through the shallow groove 1902 and is convenient to move under the extrusion of the support spring 1802. When passing through the through groove 1903, the elastic force of the support spring 1802 forces the first clamping block 1801 to be stuck inside the through groove 1903 for fixation. When it needs to be taken out, an iron rod needs to be inserted into the through groove 1903 externally to squeeze the first clamping block 1801, and then it can be pulled out.

[0037] As Figure 6 shown, the left end of the support rod 2 is connected to a standing assembly 20. The standing assembly 20 includes a bracket 2001, a side plate with grooves 2002, a second clamping block 2003, and a buffer pad 2004. Side plates with grooves 2002 are arranged at both the left and right ends of the bracket 2001, and a buffer pad 2004 is connected to the upper end of the bracket 2001. A second clamping block 2003 is connected to the lower end of the bracket 2001;

[0038] The specific operation is as follows. During the use process, the operations that need to be manually performed are the hanging and taking of the hook 5 and the movable hanging buckle 6. To facilitate the operation of operators of different heights, the bracket 2001 and the buffer pad 2004 are set as a support operating platform. Then, when it needs to be elevated, another set of standing assemblies 20 is taken out, the second clamping block 2003 is inserted into the side plate with grooves 2002 of the previous assembly, and then the buffer pad 2004 protects and stabilizes the lower end of the bracket 2001.

[0039] Working principle: Before performing the tin removal work, the operator first places the parts inside the cloth bag 703, then slides and fixes the movable hanging buckle 6 so that it can be hung on the hook 5 for fixation. Then, the cloth bag 703 is driven to move to the right by the sliding block 401, facilitating spraying by the spray pipe 1701. During the spraying process, omnidirectional spraying can be carried out through the rotation of the rotating shaft 402. Then, the stretching spring 702 acts on the cloth bag 703 to perform jittering and pulling, which can increase the shaking frequency of the cloth bag 703. Further, the motor 801 drives the toggle rod 802 to rotate, further improving the jittering effect of the cloth bag 703. The collection box 901 is placed below the cloth bag 703, so that the solution dripping from the spraying can be collected inside the collection box 901. When installing the collection box 901, by pushing the collection box 901, the rolling wheel 902 reduces the sliding friction, facilitating labor saving. The left and right ends of the collection box 901 can be clamped and fixed by the side clamping block 10. During the spraying process, the solution in the solution storage tank 11 is pumped through the liquid extraction pipe pump 15 for spraying. As the liquid level drops, it drives the buoyancy push rod 14 to move downward. Then, the buoyancy push rod 14 touches the contact block 13, turning on the switch of the buzzer 16, thereby reminding the operator to turn on the switch of the liquid inlet pipe 12 to supplement the tin removal solution. During the spraying process, the tin removal solution is ejected through the spray pipe 1701. Then, the handle ring 1702 at the upper end of the spray pipe 1701 can be manually held, which is convenient for spraying parts that are not easily sprayed in certain special situations. When the spray pipe 1701 needs to be fixed, by pressing the spray pipe 1701 inside the locking buckle 1901, the clamping block 1801 will first slide through the shallow groove 1902 and is convenient to move under the extrusion of the support spring 1802. When passing through the through groove 1903, the elastic force of the support spring 1802 forces the clamping block 1801 to be stuck inside the through groove 1903 for fixation. When it needs to be taken out, an iron rod needs to be inserted into the through groove 1903 externally to squeeze the clamping block 1801, and then it can be pulled out. During the operation process, the manual operations required are the hanging and taking of the hook 5 and the movable hanging buckle 6. To facilitate operators of different heights to operate, the bracket 2001 and the buffer pad 2004 are set as the support operating platform. Then, when it needs to be raised, a set of standing components 20 is taken out, the clamping block 2003 is inserted into the grooved side plate 2002 of the previous component, and then the buffer pad 2004 protects and stabilizes the lower end of the bracket 2001, thereby performing height stacking and being suitable for people of different heights to use.
