DETAILED DESCRIPTION

[0020] The following description is only the preferred embodiment of the utility model, and does not limit the protection scope of the utility model.

[0021] Embodiment: a kind of flexible lamp strip production automatic material supplementing device for brushing tin, as shown in Figures 1-4 It includes operating table 1, drive assembly 101, moving frame 102, brush plate 103, storage box 2, blanking hopper 3, sealing cover 4, electric push rod 5, pressing plate 6, feeding pipe 7, stock bin 8, blanking plate 9, torsion spring 10 and cleaning assembly, operating table 1 is provided with the workbench of straight, operating table 1 is installed with drive assembly 101, drive assembly 101 itself can move up and down, drive assembly 101 is slidably connected with moving frame 102, drive assembly 101 is used to drive moving frame 102 transversely, moving frame 102 lower end is connected with two brush plates 103, moving frame 102 top surface front side is connected with storage box 2, storage box 2 is connected with blanking hopper 3, blanking hopper 3 is threadedly connected with sealing cover 4, storage box 2 top is installed with electric push rod 5, the piston rod bottom of electric push rod 5 is connected with pressing plate 6, pressing plate 6 is slidably connected in storage box 2, and is tightly attached with the inner wall of storage box 2, moving frame 102 bottom is connected with stock bin 8, stock bin 8 is located in the middle of two brush plates 103, stock bin 8 is communicated with storage box 2 through feeding pipe 7, stock bin 8 is rotatably connected with blanking plate 9, blanking plate 9 pivot end is equipped with torsion spring 10, one end of torsion spring 10 is connected with blanking plate 9, the other end is connected with stock bin 8, cleaning assembly is arranged in stock bin 8, and cleaning assembly is used to clean stock bin 8.

[0022] As Figure 2 And Figure 4As shown, the cleaning assembly includes an operating rod 11, a scraper 1101 and a fixed plate 12, the operating rod 11 is slidably connected in the hopper 8 in the front-rear direction, the operating rod 11 is connected with the scraper 1101 at the end, the scraper 1101 is slidably connected in the hopper 8 and closely adheres to the inner wall of the hopper 8, and the bottom of the discharging plate 9 is rotatably connected with the fixed plate 12.

[0023] In the process of brushing tin, first, the lamp strip to be brushed tin is placed on the workbench of the operation table 1, and the mold is used to place the lamp strip. Then, the sealing cover 4 is opened, and the sealing cover 4 is threadedly connected with the discharging hopper 3 while being twisted. Finally, the sealing cover 4 is separated from the discharging hopper 3. Tin is injected into the storage box 2 through the discharging hopper 3. Then, the sealing cover 4 is resealed on the discharging hopper 3. Then, the driving assembly 101 and the electric push rod 5 are started. The driving assembly 101 moves downward by itself, so that the brush plate 103 contacts the workbench of the operation table 1. Then, the driving assembly 101 drives the moving frame 102 to move left and right horizontally, so that the brush plate 103 moves on the mold and the surface of the lamp strip. The electric push rod 5 pushes the pressing plate 6 downward through the piston rod. The pressing plate 6 slides in the storage box 2 to extrude the tin liquid. The tin enters the hopper 8 along the feeding pipe 7. The torsional force of the torsional spring 10 extrudes the discharging plate 9, so that the discharging plate 9 adheres to the surface of the hopper 8, thereby preventing the tin from falling. When a certain amount of tin accumulates in the hopper 8, the continuously entering tin will begin to extrude the discharging plate 9. The torsional spring 10 is twisted, the discharging plate 9 is rotated, and the tin falls from the hopper 8 and is evenly spread. After the moving brush plate 103 contacts the tin, the tin is brushed on the lamp strip, thereby completing the work of brushing tin. The pushing rate of the electric push rod 5 is controlled subsequently, so that uniform discharging can be realized. After the single brushing of tin is completed, the mold is taken out, and the sealing cover 4 can be twisted off at the same time. The storage box 2 is replenished, so that the uniformity during the replenishment of tin is ensured, and the efficiency of the replenishment of tin is improved.

[0024] When the same batch of lamp strips is about to be processed, the electric push rod 5 is turned off. The pressing plate 6 pushes out all the tin in the storage box 2. The worker lifts the discharging plate 9 through the fixed plate 12. The torsional spring 10 is twisted. The tin directly falls. The tin remaining on the hopper 8 and the discharging plate 9 is pulled by the worker after the fixed plate 12 is loosened. The torsional spring 10 rebounds, pulls the operating rod 11, and moves the operating rod 11 forward and backward, thereby driving the scraper 1101 to scrape the tin on the hopper 8 and the discharging plate 9. After the tin fills part of the position of the hopper 8, the discharging plate 9 is extruded and falls on the workbench. Then, the operating rod 11 is continuously pulled until the tin in the hopper 8 falls completely and is scraped flat, thereby completing the final brushing of tin. Finally, the driving assembly 101 is turned off.

[0025] As shown in the drawings, Figure 4 The fixed plate 12 is connected with the handle 13.

[0026] The handle 13 is more convenient for pulling the fixed plate 12.

[0027] AsFigure 4 As shown, the device further comprises a magnet 14, the bottom of the material bin 8 is connected with the magnet 14, the fixing plate 12 is made of magnetically attracted metal, and the magnet 14 can magnetically attract the fixing plate 12.

[0028] When the operating lever 11 is pulled, the accumulated tin can press the discharging plate 9, and the discharging plate 9 is not attached to the scraper 1101 when rotating, so that the fixing plate 12 is rotated before the operating lever 11 is pulled, the fixing plate 12 is magnetically attracted by the magnet 14, and the rotation of the discharging plate 9 is limited, and then when the scraper 1101 moves, the scraper 1101 can be attached to the discharging plate 9, the cleaning effect is optimized, and the fixing plate 12 is rotated downward to release the tin.

[0029] As shown, Figure 2 The device further comprises a rubber pad 15, and the sealing cover 4 is connected with a plurality of rubber pads 15.

[0030] The rubber pad 15 facilitates the rotation of the sealing cover 4 and increases the friction.

[0031] As shown, Figure 1 The device further comprises an observation window 16, and the storage box 2 is provided with the observation window 16 made of transparent material.

[0032] The tin storage in the storage box 2 can be directly observed through the observation window 16, so that the tin can be replenished in time.

[0033] When the device is running, the lamp strip is placed on the workbench and positioned by the mold. Then, the sealing cover 4 is opened, the tin is added to the storage box 2, and then the sealing cover 4 is tightened. The driving assembly 101 is started to drive the brush plate 103 to move, and the electric push rod 5 pushes the pressing plate 6 to extrude the tin liquid to the material bin 8. When the tin liquid in the material bin 8 accumulates to a certain degree, the discharging plate 9 rotates to release the tin liquid, and the brush plate 103 uniformly brushes the lamp strip. The speed of the electric push rod 5 can be adjusted to ensure uniform tin brushing. When the processing is completed, the electric push rod 5 stops, and the pressing plate 6 discharges the remaining tin liquid. The staff lifts the fixing plate 12 through the handle 13 to release the residual tin liquid, and uses the scraper 1101 to clean the material bin 8. The magnet 14 can assist in fixing the discharging plate 9 to ensure complete cleaning. Finally, the observation window 16 is used to monitor the tin liquid storage to replenish the material.
