[0032] refer to Figures 1-6 This application provides a material removal device for removing the material 82 of a metal part 8 on a product 9. The metal part 8 includes a spring 81 and a material 82 connected to the spring 81. The spring 81 is welded to the product 9 by a solder joint 83. A pre-crease 84 is provided between the spring 81 and the material 82. The material removal device includes a mounting frame 1, a pressure sensor 5, a suction assembly 3, and a driving device 4. The pressure sensor 5 is disposed at the top of the mounting frame 1. The suction assembly 3 is used to suction the product 9. The driving device 4 is connected to the suction assembly 3 and is used to drive the suction assembly 3 to move so that the end of the material 82 away from the spring 81 is configured to abut against the pressure sensor 5. The driving device 4 is also used to drive the product 9 to reciprocate along the normal direction 51 of the pressure sensor 5 until the metal part 8 breaks at the pre-crease 84. The material 82 separates from the spring 81 at the pre-crease 84, thereby removing the excess material 82.

[0033] This application provides a device for removing loose material. A pressure sensor 5 is mounted on a mounting frame 1. A drive device 4 moves a suction assembly 3 so that the end of the loose material 82 of the product 9 away from the spring 81 comes into contact with the pressure sensor 5. The drive device 4 then moves the product 9 back and forth along the normal direction 51 of the pressure sensor 5, either towards or away from the pressure sensor 5, causing the loose material 82 to bend around a pre-crease 84 until it breaks at the pre-crease 84, thus achieving automated removal of the loose material 82. This device can quickly and safely remove the loose material 82, thereby saving labor and improving the efficiency of loose material removal.

[0034] Specifically, the continuous material removal device of this application also includes a fixing member 16, and the pressure sensor 5 is fixedly mounted on the top of the mounting bracket 1 through the fixing member 16.

[0035] In this embodiment, product 9 is a mobile phone mid-frame, and spring piece 81 is disposed on the inner side of the mobile phone mid-frame.

[0036] refer to Figure 4 and Figure 5 The material removal device also includes a retaining edge 2, which is located at the top of the mounting frame 1. The retaining edge 2 is located on the side of the pressure sensor 5 near the drive device 4. There is a gap between the pressure sensor 5 and the retaining edge 2. The material 82 is configured to be inserted into the gap. The material 82 moves back and forth along the normal direction of the gap, that is, the normal direction of the pressure sensor 51.

[0037] Specifically, there are multiple baffles 2, which are arranged around the suction component 3 to achieve multi-directional removal of the continuous material 82 from the product 9. In this embodiment, the baffles 2 are plate-shaped, and there are six baffles 2 arranged around the component 3 to form two cuboid shapes.

[0038] Since the metal part 8 may be misaligned or poorly welded after being welded to the product 9, the spring piece 81 may fall off, causing functional defects. Pull-out force testing can be used to detect whether the spring piece 81 is welded stably and has not fallen off (otherwise it is a defective product). In this application, the connecting material 82 is inserted into the gap between the pressure sensor 5 and the retaining edge 2, and the end of the connecting material 82 away from the spring piece 81 abuts against the pressure sensor 5. Then, the driving device 4 drives the product 9 to swing back and forth along the normal direction 51 of the gap, which can transmit the force when the connecting material 82 breaks to the pressure sensor 5, and the magnitude of the pull-out force can be obtained. When the pull-out force is greater than or equal to 8N, the product 9 is OK, and when the pull-out force is less than 8N, the product 9 is NG. In addition, the pull-out force test in the prior art is a test chamber test, specifically, after applying glue to the elastic sheet 81, the instrument is used to pull it to detect the pull-out force. With the material removal device of this application, since each product 9 needs to undergo material removal 82, by setting the edge 2 and the pressure sensor 5 opposite to each other, and with the material 82 abutting against the pressure sensor 5, the pull-out force sampling test can be changed to a full pull-out force test, which can detect most of the products 9 with poor pull-out force and prevent the circulation of defective products 9.

[0039] refer to Figure 1 and Figure 6 The suction assembly 3 includes a connector 31 and a suction device. One end of the connector 31 is connected to the suction device, and the other end of the connector 31 is configured to be connected to the drive device 4. The suction device includes a main body 32 and a suction cup 33. The main body 32 is connected to the connector 31, and the suction cup 33 is disposed at the bottom end of the main body 32.

[0040] In this embodiment, the drive device 4 is a six-axis robot, and the connector 31 is a robot hand fixture. Furthermore, the robot hand fixture is screwed onto the flange shaft of the six-axis robot. Then, the six-axis robot controls the suction component 3 to pick up the product 9 and move it to the designated position, simulating manual operation to break up waste and remove waste. The parts are equipped with detection sensors. When the specified OK value is not reached, an NG signal is output to the six-axis robot, and the six-axis robot picks up the product 9 and places it in the NG position.

[0041] refer to Figure 5 and Figure 6 The number of suction cups 33 is multiple, and the multiple suction cups 33 are arranged at intervals at the bottom end of the main body 32. In this embodiment, there are four suction cups 33, with two suction cups 33 forming a group. Each group of suction cups 33 is used to pick up one product 9, which can simultaneously remove the connecting material 82 of two products 9, further accelerating production efficiency.

[0042] refer to Figure 6 The suction device also includes a first housing 34, which covers the outer periphery of the main body 32. The connector 31 passes through the first housing 34 and is connected to the main body 32. By providing the first housing 34, the splashing of waste material 82 can be avoided.

[0045] refer to Figures 2 to 4 The top plate 11 has a through hole 13. The pressure sensor 5 and the baffle 2 are both located above the through hole 13. The through hole 13 is used for the discharge of the continuous material 82.

[0046] refer to Figure 2 The continuous material removal device also includes a first row of waste hoppers 7, which is located below the top plate 11. The first row of waste hoppers 7 is slidably installed in the support frame 12 and is connected to the through hole 13. The first row of waste hoppers 7 is used to collect the removed continuous material 82 to prevent the waste from being scattered and difficult to clean.

[0047] Furthermore, it also includes a second waste hopper 71, which is located below the first waste hopper 7. The capacity of the second waste hopper 71 is greater than that of the first waste hopper 7. When the waste inside the first waste hopper 7 is full, the second waste hopper 71 is used to receive the waste poured out by the first waste hopper 7.

[0048] For details, please refer to Figure 4 The mounting frame 1 of this application also includes a bracket 14, which is located at the top of the top plate 11 and above the through hole 13. The baffle 2 is provided on the bracket 14. The bracket 14 is hollowed out, so that the waste material 82 can easily enter the through hole 13 through the hollowed-out part of the bracket 14 and fall into the first waste hopper 7.

[0049] Specifically, the top plate 11 and the support 14 are integrally formed.
