Sandblasting machines are an important component of sandblasting systems. Existing sandblasting systems have the advantages of automation and high efficiency, namely, by setting up two return lines and two sandblasting machines. After the product passes through one return line and one sandblasting machine to complete the sandblasting of one side, it passes through another sandblasting machine to perform the sandblasting operation on the other side. However, this setup not only increases costs but also greatly increases the number of required circuits and components, thereby increasing the probability of equipment malfunctions. Summary of the Invention

[0008] The invention is further configured such that: the cleaning assembly includes a slide rail, the slide rail is installed on the top of the second bracket and on one side near the transfer assembly, a slide seat is slidably connected to the top of the slide rail, a cleaning box is installed on the top of the second bracket, the slide rail passes through the interior of the cleaning box, a cleaning mechanism is installed inside the cleaning box, the loading conveyor belt and the unloading conveyor belt are respectively connected to both ends of the slide rail, and the two lifting platforms are respectively located at the connection points between the loading conveyor belt and the unloading conveyor belt and the slide rail.

[0009] The present invention is further configured such that: the sandblasting assembly includes a sandblasting box, the sandblasting box is located on the side of the second support away from the transfer assembly, the two sides of the sandblasting box are respectively connected to a first connecting box and a second connecting box, a support platform is installed on the opposing side of the first connecting box and the second connecting box, the support platform corresponding to the first connecting box is connected to the second support, two guide conveyor belts are installed inside the sandblasting box, the two ends of the two guide conveyor belts extend to the top of the two support platforms respectively, the ends of the feeding conveyor belt and the unloading conveyor belt extend to the top of one of the support platforms and are connected to the two guide conveyor belts.

[0010] The present invention is further configured such that: the return assembly includes a third support, the third support is located on the side of the sandblasting assembly away from the sandblasting disc loading and unloading assembly, a protective cover is installed on the top of the third support, and a 180° turning conveyor line is installed inside the protective cover, and the two ends of the 180° turning conveyor line are respectively connected to the ends of the two guide conveyor belts.

[0011] The invention is further configured such that: the isolation component includes a safety isolation net, the safety isolation net is disposed outside the material tray loading and unloading component, the transfer component and the sandblasting tray loading and unloading component, and windows are provided on both sides of the safety isolation net, the first bracket and the second bracket are respectively inserted into the interior of the two windows, and a door is hinged to the front side of the safety isolation net.

[0012] The present invention is further configured such that the sandblasting system of the automatic sandblasting machine operates as follows:

[0013] S1. The inside of the safety isolation net is the robotic arm operation area, and the outside of the safety isolation net and the side closest to the material tray loading and unloading component is the manual feeding area. The worker stands in the manual feeding area and puts the full material tray into the material tray loading position. The feeding belt transports the material tray in the material tray loading position to the adjacent product pick-up and drop position and stops.

[0014] S2. At the same time, a sandblasting carrier is placed on the lifting platform. The robot arm unloads the full tray at the product pick-up and drop position. The products in the tray are taken out by the robot arm and transported to the lifting platform corresponding to the feeding conveyor belt. The lifting platform lifts the sandblasting carrier on top of it and separates it from the feeding conveyor belt. At the same time, after all the products on the tray are removed, the tray is moved to the product pick-up and drop position adjacent to the tray unloading position and stops. The feeding belt continues to transport the tray in the tray loading position to the adjacent product pick-up and drop position and stops to prepare for the robot arm to pick up the material.

[0015] S3. When the sandblasting carrier on this lifting platform is fully loaded, the lifting platform falls and the sandblasting carrier falls onto the feeding conveyor belt. The sandblasting system controls the feeding conveyor belt to drive the sandblasting carrier towards the sandblasting assembly. The sandblasting carrier passes through the first connecting box, the sandblasting box and the second connecting box in sequence and performs sandblasting operation.

[0016] S4. The sandblasting carrier conveyed by S3 enters the 180° turning conveyor line, completes the return flow by the turning angle of the 180° turning conveyor line, and enters the second connecting box, the sandblasting box and the first connecting box in sequence to complete the secondary sandblasting.

[0017] S5. The sandblasting carrier after being conveyed and sandblasted by S4 is sent to the unloading conveyor belt for reverse flow. When the sandblasting carrier moves to the top of the lifting platform corresponding to the unloading conveyor belt, the lifting platform lifts the sandblasting carrier to separate it from the unloading conveyor belt.

[0018] S6. The robotic arm removes the product from the sandblasting carrier at the top of the lifting platform and moves it to the product pick-and-place position in S2, which is adjacent to the material tray unloading position. The empty material tray at this position supports the product. After the material tray is fully loaded, it is moved to the material tray unloading position for stacking and storage.

[0019] After all the products in the sandblasting carrier in S7 and S6 are removed, the slide takes up the sandblasting carrier and moves the slide and sandblasting carrier to the position of the upward conveyor belt through the slide rail. When the slide passes through the cleaning box, the cleaning mechanism in the cleaning box cleans the sandblasting carrier. When the slide moves out of the cleaning box, the sandblasting carrier is in a clean state.

[0020] S8. When the slide moves to the position of the feeding conveyor belt, the slide moves the sandblasting carrier to the lifting platform position corresponding to the feeding conveyor belt, and continues the cycle of operation through S2-S8.

[0021] The advantages of this invention are,

[0022] (1) By setting up a sandblasting disc conveyor line, when the product is conveyed on the sandblasting disc conveyor line, the sandblasting disc conveyor line and the return component work together to enable the product to complete two sandblasting operations in one sandblasting component. After sandblasting is completed, the inlet and outlet of the sandblasting disc conveyor line are separated, which facilitates the continuous feeding and discharging of the sandblasting disc conveyor line. This not only saves costs and reduces the number of parts, but also greatly reduces the probability of equipment malfunctions and improves the functionality of the equipment.

[0023] (2) If one robot cannot meet the requirements of sandblasting material supply and conveying efficiency, a reserved station is set up to increase the number of robots. When the number of robots is increased to two, the operating ranges of the two robots are range B1 and range B2, which not only reduces the pressure of a single robot handling products, but also improves the conveying and handling efficiency of the sandblasting system.

[0034] Example

[0035] Please see Figure 1-6 The present invention provides the following technical solutions:

[0036] A sandblasting system for an automatic sandblasting machine includes a material tray loading and unloading assembly 1, a sandblasting disc loading and unloading assembly 3 is provided on one side of the material tray loading and unloading assembly 1, and a transfer assembly 2 is provided between the material tray loading and unloading assembly 1 and the sandblasting disc loading and unloading assembly 3. The material tray loading and unloading assembly 1 is used to move the material trays out one by one in sequence. After the material trays are moved out, the products in the material trays are transferred and transported to the position of the sandblasting disc loading and unloading assembly 3 through the transfer assembly 2. The sandblasting disc in the sandblasting disc loading and unloading assembly 3 carries the products.

[0037] A cleaning component 4 is installed on the top of the sandblasting disc loading and unloading assembly 3 and on the side near the transfer assembly 2. The cleaning component 4 is connected to the sandblasting disc loading and unloading assembly 3. A sandblasting assembly 5 is connected to the side of the sandblasting disc loading and unloading assembly 3 away from the transfer assembly 2. A return component 6 is connected to the side of the sandblasting assembly 5 away from the sandblasting disc loading and unloading assembly 3. The sandblasting disc and the product are transported to the interior of the sandblasting assembly 5 through the sandblasting disc loading and unloading assembly 3. The sandblasting assembly 5 completes one sandblasting of the product carried in the sandblasting disc and removes it. The return component 6 is used to turn the sandblasting disc and the product that have completed one sandblasting in the sandblasting assembly 5 and re-enter the sandblasting assembly 5 for sandblasting again. The product that has completed the second sandblasting is transported back to the sandblasting disc loading and unloading assembly 3 through the sandblasting disc. The transfer assembly 2 removes the sandblasted product and puts it back to the position of the loading and unloading assembly 1 for storage. The sandblasting disc is cleaned by the cleaning component 4 after use and then reused.

[0038] An isolation component 7 is provided outside the material tray loading / unloading assembly 1, the transfer assembly 2, and the sandblasting disc loading / unloading assembly 3. The opposing sides of the material tray loading / unloading assembly 1 and the sandblasting disc loading / unloading assembly 3 extend to the outside of the isolation component 7. The isolation component 7 is used to isolate the material tray loading / unloading assembly 1, the transfer assembly 2, and the sandblasting disc loading / unloading assembly 3 from the outside. Moreover, both the material tray loading / unloading assembly 1 and the sandblasting disc loading / unloading assembly 3 extend to the outside of the isolation component 7. The inside of the isolation component 7 is the operating area of ​​the transfer assembly 2, and the outside of the isolation component 7, near the material tray loading / unloading assembly 1, is the manual feeding area. This ensures that the isolation component 7 does not affect the normal operation of the sandblasting system and can also prevent the operation of the transfer assembly 2 from threatening the safety of the workers.

[0039] The material tray loading and unloading assembly 1 includes a first support 11, which is located inside the isolation assembly 7. One side of the first support 11 extends to the outside of the isolation assembly 7. The top of the first support 11 is provided with a material tray unloading position 12 and a material tray loading position 13. Two product pick-up and drop positions 14 are provided between the material tray unloading position 12 and the material tray loading position 13. A feeding belt is provided between the material tray unloading position 12, the material tray loading position 13 and the two product pick-up and drop positions 14. The two product pick-up and drop positions 14 are arranged sequentially from the material tray loading position 13 to the material tray unloading position 12. For the product picking and product unloading positions, workers can place a full-loaded tray into the tray loading position 13 and move it from the tray loading position 13 to the product picking position via the feed belt. The transfer component 2 can pick up the products in the tray. After the products in the tray are picked up, the tray is moved to the product unloading position via the feed belt. After the sandblasting is completed, the products are collected in the tray at the product unloading position by the transfer component 2. When the tray is full, it is stacked in the tray unloading position 12 for easy removal of the tray and products by workers.

[0040] The transfer component 2 includes a base 21, which is located on one side of the first support 11. A robot arm 22 is installed on the top of the base 21. A reserved station 23 is provided on one side of the robot arm 22. The robot arm 22 and the reserved station 23 are respectively positioned opposite to the material tray loading position 13 and the material tray unloading position 12. The robot arm 22 is located between the material tray loading and unloading component 1 and the sandblasting tray loading and unloading component 3. The robot arm 22 is used to transport the products on the material tray loading and unloading component 1 to the sandblasting tray loading and unloading component 3 for the next sandblasting operation. After the product is sandblasted, the robot arm 22 can transport the sandblasted product on the sandblasting tray loading and unloading component 3 back to the material tray loading and unloading component 1 for storage.

[0041] Reserved workstation 23 is used to increase the number of robotic arms 22. When the number of robotic arms 22 is one, such as Figure 5 As shown, this robotic arm 22 is used for loading and unloading products in the material tray loading and unloading assembly 1 and the sandblasting tray loading and unloading assembly 3, and the operating range of this robotic arm 22 is area A.

[0042] When the number of robotic arms 22 is two, such as Figure 6 As shown, one robotic arm 22 is used for unloading the material from the tray loading and unloading assembly 1 and loading the product from the sandblasting tray loading and unloading assembly 3. Another robotic arm 22 is used for unloading the product from the sandblasting tray loading and unloading assembly 3 and loading the material from the tray loading and unloading assembly 1. The operating ranges of the two robotic arms 22 are area B1 and area B2, respectively. This setting avoids the situation where the two robotic arms 22 collide during operation.

[0043] The sandblasting disc loading / unloading assembly 3 includes a second support 31, which is located inside the isolation assembly 7 and on the side of the robot arm 22 away from the first support 11. A loading conveyor belt 32 and a unloading conveyor belt 33 are mounted on the top of the second support 31. The loading and unloading conveyor belts 32 and 33 are respectively positioned opposite the robot arm 22 and the reserved workstation 23. Two lifting platforms 34 are mounted on the top of the second support 31, located inside the loading and unloading conveyor belts 32 and 33 respectively. The lifting platforms 34 are used for loading and unloading operations, and each carries a sandblasting carrier. The robot arm 22 moves the product from the loading / unloading assembly 1 to the lifting platform 34 corresponding to the loading conveyor belt 32. The sandblasting carrier here carries the product. After the sandblasting carrier is fully loaded, it is sent to the sandblasting assembly 5 via the loading conveyor belt 32 for sandblasting. The product after being treated by the sandblasting assembly 5 returns via the unloading conveyor belt 33. The lifting platform 34 corresponding to the unloading conveyor belt 33 positions the sandblasting carrier, which facilitates the robot arm 22 to unload the product.

[0044] The cleaning assembly 4 includes a slide rail 41, which is installed on the top of the second bracket 31 and close to the side of the transfer assembly 2. A slide block 42 is slidably connected to the top of the slide rail 41. A cleaning box 43 is installed on the top of the second bracket 31. The slide rail 41 passes through the inside of the cleaning box 43. A cleaning mechanism is installed inside the cleaning box 43. The feeding conveyor belt 32 and the unloading conveyor belt 33 are respectively connected to the two ends of the slide rail 41, and two lifting platforms 34 are respectively located at the connection points of the feeding conveyor belt 32 and the unloading conveyor belt 33 with the slide rail 41.

[0045] The sandblasting assembly 5 includes a sandblasting box 51, which is located on the side of the second support 31 away from the transfer assembly 2. The two sides of the sandblasting box 51 are respectively connected to a first connecting box 52 and a second connecting box 53. A support platform 55 is installed on the opposing side of the first connecting box 52 and the second connecting box 53. The support platform 55 corresponding to the first connecting box 52 is connected to the second support 31. Two guide conveyor belts 56 are installed inside the sandblasting box 51. The two ends of the two guide conveyor belts 56 extend to the top of the two support platforms 55 respectively. The ends of the feeding conveyor belt 32 and the unloading conveyor belt 33 extend to the top of one support platform 55 and are connected to the two guide conveyor belts 56. The guide conveyor belts 56 are used to receive and continue to transport the sandblasting disc and product conveyed by the feeding conveyor belt 32. The first connecting box 52, the sandblasting box 51 and the second connecting box 53 cooperate to perform sandblasting operations on the product.

[0046] The return assembly 6 includes a third support 61, which is located on the side of the sandblasting assembly 5 away from the sandblasting disc loading and unloading assembly 3. A protective cover 62 is installed on the top of the third support 61. A 180° turning conveyor line 63 is installed inside the protective cover 62. The two ends of the 180° turning conveyor line 63 are respectively connected to the ends of two guide conveyor belts 56. Since there are two guide conveyor belts 56, the two guide conveyor belts 56 correspond to the loading conveyor belt 32 and the unloading conveyor belt 33 respectively.

[0047] The sandblasting disc, conveyed by the feeding conveyor belt 32, is received by the corresponding guide conveyor belt 56 and passes sequentially through the first connecting box 52, the sandblasting box 51, and the second connecting box 53, thereby completing the first sandblasting of the product. After the first sandblasting, the sandblasting disc turns through the 180° turning conveyor line 63 and re-enters the sandblasting assembly 5, which can then complete the second sandblasting of the product, greatly improving the sandblasting effect of the product.

[0048] The isolation component 7 includes a safety isolation net 71, which is located outside the material tray loading / unloading component 1, the transfer component 2, and the sandblasting disc loading / unloading component 3. Windows 73 are provided on both sides of the safety isolation net 71. A first support 11 and a second support 31 are respectively installed inside the two windows 73. A door 72 is hinged to the front of the safety isolation net 71. The safety isolation net 71 isolates the material tray loading / unloading component 1, the transfer component 2, and the sandblasting disc loading / unloading component 3 from the outside. The material tray loading / unloading component 1 and the sandblasting disc loading / unloading component 3 extend to the outside of the safety isolation net 71 through the two windows 73, thus facilitating material feeding by workers and material delivery by the sandblasting disc loading / unloading component 3. When it is necessary to increase or decrease the number of robotic arms 22 or when the system malfunctions, workers can enter the safety isolation net 71 through the door 72 to perform installation and maintenance work.

[0049] The operation steps of the sandblasting system of the automatic sandblasting machine are as follows:

[0050] Step 1: The inside of the safety isolation net 71 is the operating area of ​​the robot arm 22. The outside of the safety isolation net 71 and the side near the material tray loading and unloading component 1 is the manual feeding area. The worker stands in the manual feeding area and puts the full material tray into the material tray loading position 13. The feeding belt transports the material tray in the material tray loading position 13 to the adjacent product pick-up and drop position 14 and stops.

[0051] Step 2: Simultaneously, a sandblasting carrier is placed on the lifting platform 34. The robot arm 22 unloads the fully loaded tray at the product pick-and-place position 14. The products in the tray are taken out by the robot arm 22 and transported to the lifting platform 34 corresponding to the feeding conveyor belt 32. The lifting platform 34 lifts the sandblasting carrier on top of it and separates it from the feeding conveyor belt 32. At the same time, after all the products on the tray are removed, the tray is moved to the product pick-and-place position 14 adjacent to the tray unloading position 12 and stops. The feeding belt continues to transport the tray in the tray loading position 13 to the adjacent product pick-and-place position 14 and stops to prepare for the robot arm 22 to pick up the material.

[0052] Step 3: When the sandblasting carrier on the lifting platform 34 is fully loaded, the lifting platform 34 is lowered and the sandblasting carrier is placed on the feeding conveyor belt 32. The feeding conveyor belt 32 is controlled by the sandblasting system to drive the sandblasting carrier to the direction of the sandblasting component 5. The sandblasting carrier passes through the first connecting box 52, the sandblasting box 51 and the second connecting box 53 in sequence and performs sandblasting operation.

[0053] Step 4: The sandblasting carrier conveyed in Step 3 enters the 180° turning conveyor line 63, completes the return flow through the turning angle of the 180° turning conveyor line 63, and then enters the second connecting box 53, the sandblasting box 51 and the first connecting box 52 in sequence to complete the secondary sandblasting.

[0054] Step 5: After being conveyed and sandblasted in Step 4, the sandblasting carrier is sent to the unloading conveyor belt 33 for reverse flow. When the sandblasting carrier moves to the top of the lifting platform 34 corresponding to the unloading conveyor belt 33, the lifting platform 34 lifts the sandblasting carrier so that it is separated from the unloading conveyor belt 33.

[0055] Step 6: The robotic arm 22 takes out the product from the sandblasting carrier on the top of the lifting platform 34 and moves it to the product pick-up and drop position 14 next to the material tray unloading position 12 in Step 2. The empty material tray at this position carries the product. After the material tray is full, it is moved to the material tray unloading position 12 for stacking and storage.

[0056] After all the products in the sandblasting carrier are removed in steps seven and six, slide 42 collects the sandblasting carrier and moves slide 42 and sandblasting carrier to the position of the upward conveyor belt 32 via slide rail 41. When slide 42 passes through the cleaning box 43, the cleaning mechanism in the cleaning box 43 cleans the sandblasting carrier. When slide 42 moves out of the cleaning box 43, the sandblasting carrier is in a clean state.

[0057] Step 8: When the slide 42 moves to the position of the feeding conveyor belt 32, the slide 42 moves the sandblasting carrier to the position of the lifting platform 34 corresponding to the feeding conveyor belt 32, and the cycle continues from Step 2 to Step 8.

[0058] Specifically, the staff installs the safety isolation net 71 on the outside of the material tray loading and unloading assembly 1, the transfer assembly 2, and the sandblasting tray loading and unloading assembly 3. The inside of the safety isolation net 71 is the operating area of ​​the robot arm 22, and the outside of the safety isolation net 71 and the side closest to the material tray loading and unloading assembly 1 is the manual feeding area. The staff stands in the manual feeding area, puts the full material tray into the material tray loading position 13, and places the sandblasting carrier on the sandblasting tray loading and unloading assembly 3.

[0059] The feeding belt transports the material tray in the material position 13 of the material tray to the product picking position of the product picking position 14 and stops. The robot arm 22 unloads the full material tray at the product picking position. After all the products on the material tray are removed, the material tray moves to the product placement position of the product picking position 14 and stops. The feeding belt continues to transport the material tray in the material position 13 of the material tray to the product picking position, thereby maintaining continuous feeding.

[0060] After the product in the tray is taken out by the robot arm 22, it is transported to the lifting platform 34 corresponding to the feeding conveyor belt 32. The lifting platform 34 lifts the sandblasting carrier on top of it and separates it from the feeding conveyor belt 32, and the product is placed into the sandblasting carrier for storage.

[0061] When the sandblasting carrier on the lifting platform 34 is fully loaded, the lifting platform 34 falls and the sandblasting carrier falls onto the feeding conveyor belt 32. The sandblasting system controls the feeding conveyor belt 32 to drive the sandblasting carrier to the direction of the sandblasting component 5. The sandblasting carrier passes through the first connecting box 52, the sandblasting box 51 and the second connecting box 53 in sequence and performs the first sandblasting operation.

[0062] The sandblasting vehicle and product that have completed the first sandblasting operation enter the 180° turning conveyor line 63, return after turning at the 180° turning conveyor line 63, and then sequentially enter the second connecting box 53, the sandblasting box 51 and the first connecting box 52 to complete the second sandblasting.

[0063] After the secondary sandblasting is completed, the sandblasting carrier and the product are sent to the unloading conveyor belt 33 for reverse flow. When the sandblasting carrier moves to the top of the lifting platform 34 corresponding to the unloading conveyor belt 33, the lifting platform 34 lifts the sandblasting carrier so that it is separated from the unloading conveyor belt 33.

[0064] The robotic arm 22 takes out the product from the sandblasting carrier on the top of the lifting platform 34 and moves it to the product placement position 14. The empty tray at this position supports the product. After the tray is full, it is moved to the tray unloading position 12 for stacking and storage.

[0065] All the sandblasting carriers at the position of the lifting platform 34 corresponding to the unloading conveyor belt 33 need to be unloaded.
