Technical Field

[0001] This utility model relates to the field of sandblasting technology, specifically to an automated sandblasting device and a mobile phone manufacturing system. Background Technology

[0002] During mobile phone manufacturing, after the metal frame is machined by CNC (computer control) tools, the front and back of the hollow metal frame are not flat but composed of uneven surfaces, resulting in numerous burrs and flashes on the back, front, sides, and rear of the frame. These burrs and flashes can interfere with subsequent processes and affect the assembly and installation of various small parts, so they must be removed before assembly.

[0003] To remove burrs from metal frame products, sandblasting is often required. Existing sandblasting processes can only be performed on a single plane (such as the front or back). Due to the uneven surface, burrs in some areas are not completely removed. This results in incomplete removal of burrs on the head and tail sides of the metal frame product, affecting the precision of the assembled product. Utility Model Content

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] The following is combined with Figures 1 to 15 The following describes embodiments of the present invention.

[0021] According to an embodiment of the present invention, an automated sandblasting device is provided, comprising: a base 1 having a top surface 101; a sandblasting assembly 10 disposed above the top surface 101, the sandblasting assembly 10 having a sandblasting head 1002; and a support assembly 7 disposed above the top surface 101, the support assembly 7 including a support plate 701 and a support seat, the support seat having a receiving space, the receiving space having the support plate 701, the support plate 701 being adapted to place at least one housing 12 to be sandblasted, the support plate 701 being rotatably connected to the support seat, and in the sandblasting state, the support plate 701 being located within the sandblasting area formed by the sandblasting head 1002, the sandblasting head 1002 spraying sand towards the housing 12, and the support plate 701 being driven to rotate relative to the support seat to remove burrs from the housing 12.

[0022] The support plate 701 is located within the sandblasting area. Driven by the rotation of the support plate 701, the sand ejected from the sandblasting head 1002 can reach the head or tail side of the front or back of the housing 12, directly blasting the uneven surface of the housing 12. This allows the sand to deburr the head or tail side from different angles, completely removing burrs from the uneven areas of the housing 12. In this embodiment, the sandblasting area refers to the spatial range formed by the sand ejected from the sandblasting head 1002; that is, any area reached by the sand ejected from the sandblasting head 1002 can be considered the sandblasting area. The support plate 701 of this application is located below the sandblasting head 1002 and within the sandblasting area.

[0023] In one embodiment, such as Figure 3 , Figure 4 and Figure 6As shown, the support base includes a first support vertical plate 702 and a second support vertical plate 703 spaced apart. The first support vertical plate 702 has a first through hole, and the second support vertical plate 703 has a second through hole 7031. The central axis of the first through hole and the central axis of the second through hole 7031 coincide. A rotating power component is provided in the first through hole and / or the second through hole 7031. The support ends on both sides of the support plate 701 extend into the first through hole and the second through hole 7031, respectively, and the rotating power component is connected to the support ends. Specifically, the rotating power component is a servo motor, but it can also be a rotary cylinder or other structures, without specific limitations. The rotating power component drives the support plate 701 to rotate relative to the first support vertical plate 702 and the second support vertical plate 703. Figure 4 As shown, the support plate 701 has two placement positions 7012, and each placement position 7012 holds a housing 12 to be sandblasted. In this embodiment... Figure 4 One placement position 7012 of the support plate 701 is where the housing 12 is placed, and the other placement position 7012 is not where the housing 12 is placed.

[0024] In one embodiment, such as Figure 3 , Figure 6 As shown, a first horizontal linear module 11 is provided on the top surface 101 of the base 1. The support base includes a support base plate 706. A first support vertical plate 702 and a second support vertical plate 703 are provided on the first surface 7061 of the support base plate 706. The second surface of the support base plate 706 is connected to the first horizontal linear module 11. The first horizontal linear module 11 drives the support base plate 706 to move relative to the base 1. The first horizontal linear module 11 drives the support base and the support plate 701 to move along the length direction of the first horizontal linear module 11. It should be noted that this embodiment does not limit the specific structure of the first horizontal linear module 11. The first horizontal linear module 11 can be a belt type, ball screw type, linear motor type, telescopic cylinder type, etc.

[0025] In one embodiment, such as Figure 1 , Figure 2 and Figure 3As shown, the base 1 includes a support frame 13, which is equipped with a second horizontal linear module 9. The second horizontal linear module 9 is connected to the sandblasting assembly 10 and drives the sandblasting assembly 10 to move relative to the base 1. The central axis of the first horizontal linear module 11 is perpendicular to the central axis of the second horizontal linear module 9. The sandblasting assembly 10 also includes a vertical linear module 1001, which is fixedly connected to the sandblasting head 1002. The vertical linear module 1001 drives the sandblasting head 1002 to move closer to or away from the top surface 101 of the base 1. Through the second horizontal linear module 9 and the vertical linear module 1001, the sandblasting head 1002 moves in two directions. Combined with the movement of the first horizontal linear module 11 and the rotating power component, three-axis linkage and rotation within the spatial range are achieved. It should be noted that this embodiment does not impose specific structural limitations on the second horizontal linear module 9 and the vertical linear module 1001. Both can be belt-type, ball screw-type, linear motor-type, telescopic cylinder-type, etc.

[0026] In one embodiment, such as Figure 3 , Figure 5 and Figure 6 As shown, it also includes a cover plate picking and placing assembly 8, which is disposed on the top surface 101 of the base 1. The cover plate picking and placing assembly 8 includes a protective cover plate 804, a connecting plate 803, a gripping claw 805, and a lifting power component 802. The lifting power component 802 is connected to the gripping claw 805 through the connecting plate 803. The gripping claw 805 includes a gripping power component 8053 and a gripping end 8051. A gripping end 8051 is provided on each side of the gripping power component 8053. The gripping power component 8053 controls the two gripping ends 8051 to clamp or release the protective cover plate 804. In the sandblasting state, the two gripping ends 8051 release the protective cover plate 804, and the first clamping plate 704 and the second clamping plate 705 provided on both sides of the support plate 701 clamp the protective cover plate 804. Figure 5 As shown, each gripper end 8051 is provided with two gripper protrusions 8052. Each gripper protrusion 8052 is adapted to the gripping groove 8041 on the side of the protective cover plate 804, so that the gripper protrusions 8052 of the gripper end 8051 can be controlled by the gripping power component 8053 to clamp or release the protective cover plate 804. The lifting power component 802 controls the raising or lowering of the gripping power component 8053 and the gripper end 8051. To control the movement of the first clamping plate 704 and the second clamping plate 705, as follows: Figure 14 , Figure 15As shown, the support plate 701 is also equipped with a first clamping power component and a second clamping power component 707. The first clamping power component is connected to the first clamping plate 704, and the second clamping power component 707 is connected to the second clamping plate 705. Specifically, the first clamping power component and the second clamping power component 707 are clamping cylinders, the gripping power component 8053 is a gripping cylinder, and the lifting power component 802 is a lifting cylinder.

[0027] In one embodiment, such as Figure 4 , Figure 6 As shown, both the support plate 701 and the protective cover plate 804 are rectangular. Each of the four corners of the support plate 701 has a positioning boss 7011, and each of the four corners of the protective cover plate 804 has a positioning groove. The positioning bosses 7011 and the positioning grooves are fitted together. After the protective cover plate 804 is placed on the support plate 701, the positioning bosses 7011 and the positioning grooves cooperate to position the protective cover plate 804. It should be noted that there is only one set of support components 7 in this application. Figure 6 To facilitate understanding by those skilled in the art, the number of support components 7 is shown in two groups: one group shows the position of support components 7 in the loading state, and the other group shows the position of support components 7 in the unloading state. That is, support components 7 in both states are shown in the same figure. In actual use, only one set of support components 7 needs to be set.

[0028] In one embodiment, such as Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, it also includes a sealing cavity shell 2, which is fixedly connected to the base 1. The sealing cavity shell 2 is provided with a lifting door 203, which is slidably connected to the front side plate 201 of the sealing cavity shell 2. The lifting door 203 is used to open or close the opening 202 of the sealing cavity shell 2. The sealing cavity shell 2 and the base 1 work together to form a sandblasting space to prevent sand from flowing out during the sandblasting process. Figure 7 , Figure 8 As shown, the lifting door body 203 is slidably connected to the front side plate 201 via a slide rail 204 provided on the front side plate 201, and the lifting door body 203 is provided with a position sensor 205, and the front side plate 201 is located close to the robotic arm 5.

[0029] In one embodiment, such as Figure 1 , Figure 6As shown, it also includes a recovery pipeline 4.

The recovery port of the recovery pipeline 4 is connected to the sealing plate 3, and the recovery pipeline 4 is suitable for connecting to the air extraction machine. It should be noted that the sealing chamber shell 2 and the sealing plate 3 are located on both sides of the support frame 13. The sealing chamber shell 2, the sealing plate 3 and the base 1 form a sandblasting space. A gap is left between the sealing chamber shell 2 and the support frame 13 to allow external gas to enter into the sandblasting space. The recovery pipeline 4 absorbs the sand and gravel sprayed by the sandblasting head 1002 through suction, realizing the recovery of the sand and gravel. The recovered sand and gravel can be transported to the sandblasting machine through the pipeline for recycling. The sandblasting head 1002 is connected to the sandblasting machine through the pipeline.

[0030] According to an embodiment of the present invention, another aspect provides a mobile phone manufacturing system, including the aforementioned automated sandblasting device.

[0031] In one embodiment, such as Figure 1 , Figure 2 , Figure 9 , Figure 10 and Figure 11 As shown, the system also includes a blister pack 6, a hand fixture 503, and a robotic arm 5. The blister pack 6 has several receiving slots 601, each containing a housing 12. The fixed shaft of the robotic arm 5 passes through the mounting hole 5031 of the hand fixture 503. The hand fixture 503 has several suction nozzles 5032, which are used to adsorb the housing 12. The robotic arm 5 includes a control box 501 and a multi-degree-of-freedom arm 502. The controller in the control box 501 controls the multi-degree-of-freedom arm 502, and each of the two sides of the multi-degree-of-freedom arm 502 has a fixed shaft, which can be fixedly connected to the hand fixture 503. It should be noted that the suction nozzles 5032 are connected to an air pump through pipes, and the air pump draws air to make the suction nozzles 5032 adsorb the housing 12. In this embodiment, two adjacent suction nozzles 5032 adsorb one housing 12.

[0032] To achieve automatic control, the controller in the control box 501 is connected to the air extractor, sandblasting machine, air pump, multi-degree-of-freedom arm 502, first linear motion module, second linear motion module, vertical linear module 1001, rotary power component, gripping power component 8053, lifting power component 802, position sensor 205, first clamping power component and second clamping power component 707, etc.

[0033] In this embodiment, as Figure 12 , Figure 13As shown, the housing 12 has a front housing portion 1201 and a back housing portion 1205. The first burr portion 1202, the second burr portion 1203, the third burr portion 1204, and the fourth burr portion 1206 of the front housing portion 1201 are all locations to be sandblasted, and the fifth burr portion 1207 of the back housing portion 1205 is also a location to be sandblasted. Both the front housing portion 1201 and the back housing portion 1205 are configured with concave and convex shapes. In this embodiment, housing 12 refers to the metal frame of a mobile phone.

[0034] A method for using an automated sandblasting device, comprising a feeding state, a plate unloading state, a sandblasting state, and a unloading state, includes the following steps: (1) In the feeding state, the lifting door 203 rises and opens the opening 202 on the front side plate 201. The controller controls the multi-degree-of-freedom arm 502 to connect with the palm jig 503. The air pump draws air so that different air nozzles of one palm jig 503 adsorb two parallel shells 12 from the suction shell. After the two shells 12 are adsorbed, the multi-degree-of-freedom arm 502 moves to send the adsorbed shells 12 into the sealed cavity shell 2. The first horizontal linear module 11 drives the support component 7 to be set close to the front side plate 201. The support plate 701 is kept horizontal until the shell 12 is placed into the placement position 7012 of the support plate 701. The front shell part 1201 of the shell 12 in the placement position 7012 is set upward. The palm jig 503 exits the sealed cavity shell 2 and the lifting door 203 closes the opening 202. (2) In the plate-laying state, the first horizontal linear module 11 drives the support component 7 to move to the bottom of the cover plate pick-and-place component 8, and the lifting power component 802 drives the gripper 805 to descend to the preset position, so that the protective cover plate 804 is just above the support plate 701 (the positioning boss 7011 enters the positioning groove). The gripping power component 8053 controls the gripper protrusion 8052 of the gripper end 8051 to separate from the gripping groove 8041. The first clamping plate 704 and the second clamping plate 705 clamp the protective cover plate 804. The lifting power component 802 drives the gripper 805 to rise, and the first horizontal linear module 11 drives the support component 7 to move to the sandblasting position. (3) In the sandblasting state, the second horizontal linear module 9 and the vertical linear module 1001 work together to move the sandblasting head 1002 to the sand outlet position. The protective cover plate 804 and the support plate 701 are located below the sandblasting head 1002. The sandblasting head 1002 sprays sand into the hole of the protective cover plate 804. At the same time, the rotating power component drives the support plate 701 to rotate around the central axis of the first through hole (the rotation method can be reciprocating, or a single counterclockwise rotation, or a single clockwise rotation, etc.). The first horizontal linear module 11 drives the support assembly 7 to move, thereby deburring the burrs on the front shell 1201. After deburring, the rotating power component drives the support plate 701 to rotate 180° so that the reverse shell portion 1205 of the housing 12 faces upward. The rotating power component drives the support plate 701 to rotate around the central axis of the first through hole (the rotation method can be reciprocating, or a single counterclockwise rotation, or a single clockwise rotation, etc.). The first horizontal linear module 11 drives the support assembly 7 to move, thereby deburring the burrs on the reverse shell portion 1205. The rotating power component drives the support plate 701 to rotate 180° so that the front shell portion 1201 of the housing 12 faces upward. During the deburring process, the vacuum pump operates to recover the sprayed sand and gravel. (4) In the unloading state, after the shell 12 is completely deburred, the first horizontal linear module 11 drives the support component 7 to move to the bottom of the cover plate pick-up and drop component 8. The lifting power component 802 drives the gripper 805 to descend to the preset position. The gripper power component 8053 controls the gripper protrusion 8052 of the gripper end 8051 to enter the gripper groove 8041. The lifting power component 802 drives the gripper 805 to rise. The first horizontal linear module 11 drives the support component 7 to move to the position close to the opening 202 of the front side plate 201. The lifting door 203 rises and opens the opening 202 on the front side plate 201. The palm jig 503 enters the sealed cavity and moves the shell 12 with the deburred part through the suction nozzle 5032 to the outside of the sealed cavity and then places it in the blister shell. The deburring process of the shell 12 is thus completed.

[0035] It should be noted that in this embodiment, the robotic arm 5 can correspond to one automated sandblasting device, or one robotic arm 5 can correspond to two or more automated sandblasting devices. The automated sandblasting device in this embodiment realizes a cycle of "loading state → plate release state → sandblasting state → unloading state → loading state → plate release state...".

[0036] The automated sandblasting device provided in this embodiment has the following advantages: (1) It realizes automated feeding, sandblasting and unloading, solves the problem of manual feeding and unloading, and improves production efficiency; (2) It realizes three-axis linkage and can rotate during the sandblasting process, which can effectively remove the burrs on the surface of the front shell 1201 and the side shell, as well as the side wall; (3) By setting up the recycling pipeline 4, it realizes the recycling and reuse of sand and gravel, without the need for manual collection and then adding sand and gravel, thus improving work efficiency; (4) The protective cover plate 804 protects the parts of the front shell 1201 that do not need to be sandblasted, thus protecting the front shell 1201, and the bottom design of the placement position 7012 protects the parts of the back shell 1205 that do not need to be sandblasted, thus protecting the back shell 1205.

[0037] As an alternative implementation, the number of placement positions 7012 on the support plate 701 can be 1, 3, 4 or even more.

[0038] As an alternative implementation, the number of nozzles adsorbing a housing 12 may be one, three, four or even more.

[0039] As an alternative implementation, the gripping power component 8053, the lifting power component 802, the first clamping power component and the second clamping power component 707 can also be telescopic motors or telescopic hydraulic cylinders.
