Description

Technical Field

[0001] The present application relates to the technical field of ultrasonic welding, and more specifically, to a misalignment pressing mechanism, a processing device, and a method for workpiece processing. Background Art

[0002] Some light-emitting diode (LED) devices need to be ultrasonically welded. Figure 1 FIG. is a schematic diagram of an LED device mounted on a loading plate. Figure 2 For Figure 1 Partial enlarged view of point A in Figure 2 , Before ultrasonic welding, multiple LED devices (i.e., workpiece C1) are usually mounted on the loading plate C2. In order to reliably ultrasonically weld the LED devices, the LED devices need to be positioned. Generally, the loading plate C2 is pressed against the workbench by a pressing plate, and the LED devices are indirectly positioned by pressing the loading plate C2. The pressing plate is provided with avoidance openings for avoiding the LED devices and the welding head inside. However, due to the limitation of the spatial structure of the ultrasonic welding environment, the designed thickness of the pressing plate is usually thin, and there are avoidance openings inside the pressing plate, which makes the pressing plate prone to deformation. The area with a large deformation of the pressing plate cannot reliably press the loading plate C2; in addition, when the loading plate C2 itself is deformed in the thickness direction, there will also be gaps between the loading plate C2 and the pressing plate, and between the loading plate C2 and the workbench. The pressing plate cannot uniformly apply pressure to the entire loading plate C2, resulting in unreliable pressing of some areas of the loading plate C2, directly leading to poor positioning of the LED devices and ultimately affecting the ultrasonic welding quality of the LED devices. Summary of the Invention

[0003] The embodiments of the present application are used to solve the technical problem that the loading plate with LED devices cannot be reliably pressed during ultrasonic welding in the prior art.

[0004] In order to solve the above technical problem, the embodiments of the present application provide a misalignment pressing mechanism, adopting the following technical solutions:

[0005] A misalignment pressing mechanism for positioning a loading plate carrying workpieces, the misalignment pressing mechanism includes a pressing member and an abutting mechanism;

[0006] The pressing member abuts against one side of the loading plate adjacent to the workpiece, and an avoidance opening is provided at a position corresponding to the workpiece on the pressing member;

[0007] The abutting mechanism includes a supporting member, an abutting member, and a driving device. The supporting member and the abutting member are driven by the driving device. The supporting member and the abutting member can abut against different regions on the side of the material carrier plate away from the workpiece either successively or simultaneously. The supporting member and the abutting member can generate displacements with different magnitudes relative to the pressing member.

[0008] At least a section of the abutting member adjacent to the workpiece is made of a soft material.

[0009] Further, the abutting member can pass through the supporting member and then abut against the side of the material carrier plate away from the workpiece.

[0010] Further, the abutting member includes an abutting plate and an abutting head. The abutting head is arranged on the abutting plate. The abutting plate is driven by the driving device. The abutting head can pass through the supporting member and then abut against the side of the material carrier plate away from the workpiece.

[0011] Further, the driving device includes a stage and a driver. The stage is driven by the driver. The supporting member and the abutting plate are mounted on the stage. The abutting plate is located between the supporting member and the stage.

[0012] Further, an elastic member is arranged between the supporting member and the stage.

[0013] Further, a first limiting portion is arranged on the supporting member, and a second limiting portion is arranged on the driving device. There is a certain distance between the first limiting portion and the second limiting portion. This distance is used to limit the maximum movement amount of the abutting member relative to the supporting member.

[0014] Further, the abutting head is made of a soft material.

[0015] Further, a set number of through holes are arranged inside the supporting member. The number of the abutting heads is equal to or less than the number of the through holes. Each abutting head can pass through the corresponding through hole.

[0016] To solve the above technical problems, an embodiment of the present application further provides a processing device, which adopts the following technical solution:

[0017] A processing device includes the above-mentioned misalignment pressing mechanism.

[0018] To solve the above technical problems, an embodiment of the present application further provides a method for processing a workpiece, which adopts the following technical solution:

[0019] A method for processing a workpiece, characterized in that: using the above-mentioned processing device, the method for processing the workpiece includes the following steps:

[0020] Convey the material carrier plate carrying the workpiece to between the pressing member and the abutting mechanism, and align the workpiece with the avoidance opening;

[0021] Control the pressing member to move towards the side of the material carrier plate adjacent to the workpiece, control the supporting member and the abutting member to move towards the side of the material carrier plate away from the workpiece, control the pressing member and the supporting member to simultaneously abut against the material carrier plate. After the supporting member abuts against the side of the material carrier plate away from the workpiece, control the abutting member to continue moving towards the side of the material carrier plate away from the workpiece, and control the abutting member and the supporting member to abut against different regions on the side of the material carrier plate away from the workpiece until both the side of the material carrier plate adjacent to the workpiece and the side away from the workpiece are pressed;

[0022] Control the processing head of the processing equipment to enter the avoidance opening to process the workpiece.

[0023] Compared with the prior art, the embodiments of the present application mainly have the following beneficial effects: The workpiece installed on the material carrier plate is positioned by the offset pressing mechanism. The pressing member of the offset pressing mechanism abuts against the side of the material carrier plate adjacent to the workpiece, and the abutting mechanism of the offset pressing mechanism abuts against the side of the material carrier plate away from the workpiece. The driving device of the abutting mechanism drives the supporting member and the abutting member, and can control the pressing member and the supporting member to simultaneously abut against the material carrier plate. The supporting member and the abutting member can abut against different regions on the side of the material carrier plate away from the workpiece either successively or simultaneously. The supporting member and the abutting member can generate displacements with different magnitudes relative to the pressing member, which can eliminate the gaps between the material carrier plate and the pressing member, between the material carrier plate and the supporting member, and between the material carrier plate and the abutting member. By making at least a section of the abutting member adjacent to the workpiece made of a soft material, it can ensure that different regions on both sides of the material carrier plate can be reliably pressed when there are slight height differences in the workpiece, enabling the workpiece installed on the material carrier plate to be well positioned, and improving the processing quality of the workpiece. For example, it can improve the ultrasonic welding quality of LED devices. Description of the Drawings

Detailed implementation manners

[0043] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above drawings are intended to cover non-exclusive inclusion. The terms "first", "second", etc. in the specification and claims of this application or the above drawings are used to distinguish different objects and not to describe a specific order.

[0044] Reference to "embodiment" herein means that a specific feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of this application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0045] Figure 3 Schematic three-dimensional structure diagram of a misaligned pressing mechanism according to an embodiment of this application Figure 4 is Figure 3 explosion diagram of the misaligned pressing mechanism in Figure 4 Referring to

[0046] Continue to refer to Figure 4 , the misaligned pressing mechanism 1000 includes a pressing member 1 and an abutting mechanism 2. The pressing member 1 abuts against one side of the loading plate C2 adjacent to the workpiece C1. Figure 5 isFigure 4 Partial enlarged view at position B. An avoidance opening 11 (see Figure 5 ) is provided on the pressing member 1 corresponding to the position of the workpiece C1 to prevent the pressing member 1 from damaging the workpiece C1. At the same time, the processing head for processing the workpiece C1 enters and exits the avoidance opening 11 so that the processing head can process the workpiece C1. For example, after the welding head enters the avoidance opening 11, ultrasonic welding is performed on the LED device, and after the welding is completed, the welding head exits from the avoidance opening 11.

[0047] Continue to refer to Figure 4 , the abutting mechanism 2 includes a supporting member 21, an abutting member 22 and a driving device 23. The supporting member 21 and the abutting member 22 are driven by the driving device 23. The supporting member 21 and the abutting member 22 can abut against different regions on the side of the loading plate C2 away from the workpiece C1 either successively or simultaneously or at the same time. The supporting member 21 and the abutting member 22 can generate displacements of different magnitudes relative to the pressing member 1. To better understand the abutting mechanism 2, reference can also be made to Figure 6 , Figure 6 is Figure 4 Schematic three-dimensional structure diagram of the abutting mechanism 2 in

[0048] If the supporting member 21 abuts against the side of the loading plate C2 away from the workpiece C1 before the abutting member 22, when there is a gap between the region on the loading plate C2 opposite to the abutting member 22 and the pressing member 1, since the supporting member 21 and the abutting member 22 can generate displacements of different magnitudes relative to the pressing member 1, after the supporting member 21 abuts against the side of the loading plate C2 away from the workpiece C1 and stops moving, the abutting member 22 can continue to move towards the pressing member 1 until the gap between the region on the loading plate C2 opposite to the abutting member 22 and the pressing member 1 is eliminated.

[0049] If the abutting member 22 abuts against the side of the loading plate C2 away from the workpiece C1 before the supporting member 21, when there is a gap between the region on the loading plate C2 opposite to the supporting member 21 and the pressing member 1, since the supporting member 21 and the abutting member 22 can generate displacements of different magnitudes relative to the pressing member 1, after the abutting member 22 abuts against the side of the loading plate C2 away from the workpiece C1 and stops moving, the supporting member 21 can continue to move towards the pressing member 1 until the gap between the region on the loading plate C2 opposite to the supporting member 21 and the pressing member 1 is eliminated.

[0050] If the abutting member 22 and the supporting member 21 simultaneously abut against the side of the material-loading plate C2 away from the workpiece C1, there will be two situations: The first situation is that there is a gap between the area of the material-loading plate C2 opposite to the supporting member 21 and the pressing member 1. In this case, since the supporting member 21 and the abutting member 22 can produce displacements with different magnitudes relative to the pressing member 1, after the abutting member 22 abuts against the material-loading plate C2 and stops moving, the supporting member 21 can continue to move towards the pressing member 1 until the gap between the area of the material-loading plate C2 opposite to the supporting member 21 and the pressing member 1 is eliminated. The second situation is that there is a gap between the area of the material-loading plate C2 opposite to the abutting member 22 and the pressing member 1. In this case, since the supporting member 21 and the abutting member 22 can produce displacements with different magnitudes relative to the pressing member 1, after the supporting member 21 abuts against the material-loading plate C2 and stops moving, the abutting member 22 can continue to move towards the pressing member 1 until the gap between the area of the material-loading plate C2 opposite to the abutting member 22 and the pressing member 1 is eliminated.

[0051] Obviously, since the pressing member 1 abuts against the side of the material-loading plate C2 close to the workpiece C1, and the supporting member 21 and the abutting member 22 can produce displacements with different magnitudes relative to the pressing member 1, the supporting member 21 and the abutting member 22 can finally abut against the side of the material-loading plate C2 away from the workpiece C1, that is, all areas on the side of the material-loading plate C2 away from the workpiece C1 are pressed.

[0052] Furthermore, in this embodiment, at least a section of the abutting member 22 close to the workpiece C1 is made of a soft material, so that when there are slight height differences in the workpiece C1, different deformation amounts can be generated in the areas corresponding to different workpieces C1 at the end of the abutting member 22 abutting against the material-loading plate C2, which is beneficial to making the heights of different workpieces C1 tend to be consistent.

[0053] In summary, the present application can eliminate the gaps between the material-loading plate C2 and the pressing member 1, between the material-loading plate C2 and the supporting member 21, and between the material-loading plate C2 and the abutting member 22, ensure that different areas on both sides of the material-loading plate C2 can be reliably pressed, ensure good positioning effect of the workpiece C1 on the material-loading plate C2, and improve the processing quality of the workpiece C1.

[0054] Further, in this embodiment, during the process of pressing the pressing member 1 against the side of the material-loading plate C2 close to the workpiece C1, the force driving the pressing member 1 to abut against the material-loading plate C2 acts on two opposite ends of the pressing member 1. Therefore, after the pressing member 1 abuts against the side of the material-loading plate C2 close to the workpiece C1, gaps are likely to form in the regions corresponding to the middle part of the pressing member 1 on the side of the material-loading plate C2 away from the workpiece C1 and / or on the side close to the workpiece C1. Thus, in this embodiment, the abutting member 22 can pass through the supporting member 21 and abut against the side of the material-loading plate C2 away from the workpiece C1, so that the abutting member 22 can abut against the middle part of the side of the material-loading plate C2 away from the workpiece C1, facilitating the elimination of the gaps in the middle part of the side of the material-loading plate C2 away from the workpiece C1 and / or on the side close to the workpiece C1. Of course, in other embodiments, the position where the force driving the pressing member 1 to abut against the material-loading plate C2 acts on the pressing member 1 can be adjusted. Correspondingly, the regions where gaps are likely to form on the side of the material-loading plate C2 away from the workpiece C1 and / or on the side close to the workpiece C1 may change, and the abutting positions of the supporting member 21 and the abutting member 22 on the side of the material-loading plate C2 away from the workpiece C1 can be adjusted accordingly.

[0055] Figure 7 For Figure 4 the schematic diagram of the abutting member 22 in Figure 8 For Figure 7 the partial enlarged view at position C of Figure 7 Further, referring to

[0056] In this embodiment, the material-loading plate C2 is a flat plate, and the sides of the abutting head 222, the supporting member 21, and the pressing member 1 facing the material-loading plate C2 are all flat surfaces. Of course, in other embodiments, the shape of the material-loading plate C2 can be adjusted according to needs, and the sides of the supporting member 21, the abutting head 222, and the pressing member 1 facing the material-loading plate C2 are adjusted accordingly.

[0057] Further, in this embodiment, the driving device 23 includes a stage 231 (refer to Figure 4 ), and a driver (not shown in the figure). The stage 231 is driven by the driver. The supporting member 21 and the abutting top plate 221 are mounted on the stage 231. The abutting top plate 221 is located between the supporting member 21 and the stage 231, which facilitates the abutting head 222 on the abutting top plate 221 to pass through the supporting member 21 and then abut against the side of the loading plate C2 away from the workpiece C1.

[0058] Further, in this embodiment, an elastic member 24 (refer to Figure 4 ) is provided between the supporting member 21 and the stage 231. When the supporting member 21 abuts against the side of the loading plate C2 away from the workpiece C1, the supporting member 21 stops moving. Since the elastic member 24 can be compressed, the abutting member 22 can still move further towards the pressing member 1 under the drive of the driver until the gap in the area where the side of the loading plate C2 away from the workpiece C1 or / and the side adjacent to the workpiece C1 facing the abutting member 22 is eliminated.

[0059] Further, in this embodiment, the elastic member 24 is a compression spring 241 (refer to Figure 4 ). Of course, in other embodiments, the elastic member 24 can be of other structures, as long as it can produce elastic deformation and can cooperate with the movement of the abutting member 22.

[0060] In this embodiment, the supporting member 21 and the abutting member 22 are driven by the same driver. Relying on the elastic member 24, after the supporting member 21 stops moving, the abutting member 22 can continue to move towards the pressing member 1 under the drive of the driver. In other embodiments, the supporting member 21 and the abutting member 22 can be respectively provided with drivers. When the supporting member 21 abuts against the side of the loading plate C2 away from the workpiece C1, the driver connected to the supporting member 21 is controlled to stop driving the supporting member 21, and the driver connected to the abutting member 22 is controlled to continue driving the abutting member 22 until the gap in the area where the side of the loading plate C2 away from the workpiece C1 or / and the side adjacent to the workpiece C1 facing the abutting member 22 is eliminated. Correspondingly, the elastic member 24 can be omitted.

[0061] There is a state where, after the supporting member 21 abuts against the side of the loading plate C2 away from the workpiece C1, and before the pressing head 222 abuts against the side of the loading plate C2 away from the workpiece C1, there is no gap between the side of the loading plate C2 adjacent to the workpiece C1 and the pressing member, and the loading plate C2 itself does not deform, that is, the side of the loading plate C2 away from the workpiece C1 is flat. When in this state, before the supporting member 21 abuts against the loading plate C2, if the end of the pressing head 222 adjacent to the loading plate C2 protrudes from the side of the supporting member 21 adjacent to the loading plate C2, the pressing head 222 is likely to damage the loading plate C2 and the workpiece C1 on the loading plate C2. To avoid this adverse consequence, in this embodiment, before the supporting member 21 abuts against the loading plate C2, the end of the pressing head 222 adjacent to the loading plate C2 is recessed into the side of the supporting member 21 adjacent to the loading plate C2 by 0 to 0.5 mm, preferably 0.3 mm. Figure 9 is Figure 3 the front view of the dislocation pressing mechanism 1000 in Figure 10 is Figure 9 the sectional view taken along D-D of Figure 11 is Figure 10 the partial enlarged view at E of. The value by which the end of the pressing head 222 adjacent to the loading plate C2 is recessed into the side of the supporting member 21 adjacent to the loading plate C2 is called the recessed value d1 (refer to Figure 11 ), that is, in this embodiment, the recessed value d1 is 0 to 0.5 mm, preferably 0.3 mm. The larger the recessed value d1, the longer the time required for the pressing head 222 to move to abut against the side of the loading plate C2 away from the workpiece C1, wasting time and having low efficiency. The smaller the recessed value d1, the higher the control requirement for the movement amount accuracy of the pressing head 222. Specifically, in implementation, the recessed value d1 can be selected according to the actual situation. In other embodiments, the recessed value d1 can also be greater than 0.5 mm. In other embodiments, if the structural shape of the pressing member 22 is different from that of this embodiment, to avoid the adverse consequence that the pressing head 222 is likely to damage the loading plate C2 and the workpiece C1 on the loading plate C2 in this state, the following requirements can be set: when the supporting member 21 abuts against the side of the loading plate C2 away from the workpiece C1 before the pressing member 22, before the supporting member 21 abuts against the loading plate C2, the end of the pressing member 22 adjacent to the loading plate C2 is recessed into the side of the supporting member 21 adjacent to the loading plate C2 by 0 to 0.5 mm.

[0062] Figure 12 is Figure 9Partial enlarged view at F. Further, in this embodiment, a first limiting portion X1 is provided on the supporting member 21, and a second limiting portion X2 is provided on the driving device. The distance d2 between the first limiting portion X1 and the second limiting portion X2 is 0.7 mm to 1 mm. The distance d2 is used to limit the maximum movement amount of the abutting member 22 relative to the supporting member 21, and the distance d2 is preferably 0.8 mm. The larger the distance d2, the larger the maximum amount that the abutting member 22 protrudes from the supporting member 21, and the larger the maximum abutting force on the side of the loading plate C2 away from the workpiece C1. If the maximum abutting force is too large, it is easy to damage the loading plate C2 and the workpiece C1 on the loading plate C2. Therefore, the distance d2 can prevent the loading plate C2 and the workpiece C1 on the loading plate C2 from being damaged due to the excessive abutting force of the abutting member 22 on the side of the loading plate C2 away from the workpiece C1. If the distance d2 is less than the recessed value d1, the abutting member 22 will not protrude from the supporting member 21, so that the abutting member 22 cannot abut against the side of the loading plate C2 away from the workpiece C1. In other embodiments, the distance d2 can be adjusted according to the recessed value d1, as long as the abutting member 22 can abut against the side of the loading plate C2 away from the workpiece C1 to eliminate the gap, and prevent the abutting member 22 from damaging the loading plate C2 and the workpiece C1 on the loading plate C2. Specifically, the second limiting portion X2 is provided on the stage 231 of the driving device 23. Figure 13 is Figure 4 a schematic view of the top plate mounting seat 2311 in Figure 14 mounted on the base 2312, Figure 4 and Figure 13 is an exploded schematic view of the stage 231 in Figure 15 Refer to Figure 4 the stage 231 includes a top plate mounting seat 2311 and a base 2312. The top plate mounting seat 2311 is mounted at the central portion of the base 2312. The driver drives the base 2312, and the end face of the base 2312 facing the supporting member serves as the second limiting portion X2. Figure 16 is Figure 4 a schematic view of the supporting member 21 in Figure 17 and Figure 4 is a schematic view of the supporting member 21 in another direction in Figure 15 and Figure 16 different from Figure 15 the direction shown in Figure 15)。In other embodiments where the supporting member abuts against the side of the material carrier plate C2 away from the workpiece C1 prior to the abutting member, if the structural shape of the driving device is different from that of this embodiment, the position and specific form of the second limiting portion provided on the driving device can be adjusted, and the first limiting portion on the supporting member can be adjusted accordingly, as long as the maximum movement amount of the abutting member can be restricted to ensure that the abutting member can abut against the side of the material carrier plate C2 away from the workpiece C1 to eliminate the gap, and to avoid the abutting member damaging the material carrier plate C2 and the workpiece C1 on the material carrier plate C2. The distance d2 between the first limiting portion and the second limiting portion can also be 0.7 mm to 1 mm, or can be adjusted to other values according to the recess value d1.

[0063] In this embodiment, the supporting member abuts against the side of the material carrier plate C2 away from the workpiece C1 prior to the abutting member. Of course, in other embodiments, according to the change of the gap position on the side of the material carrier plate C2 away from the workpiece C1 or / and adjacent to the workpiece C1, the supporting member can abut against the side of the material carrier plate C2 away from the workpiece C1 after the abutting member, or the supporting member and the abutting member can abut against the side of the material carrier plate C2 away from the workpiece C1 simultaneously, as long as the gap can be eliminated.

[0064] Furthermore, in this embodiment, the abutting head 222 is made of silica gel material, and the silica gel material is a soft material, which can avoid the abutting head 222 with too high hardness from damaging the material carrier plate C2 and the workpiece C1 on the material carrier plate C2. Of course, in other embodiments, the abutting head 222 can be made of other soft materials, as long as it can avoid the abutting head 222 with too high hardness from damaging the material carrier plate C2 and the workpiece C1 on the material carrier plate C2, and can form an abutting force on the material carrier plate C2 to eliminate the gap on the side of the material carrier plate C2 away from the workpiece C1 or / and adjacent to the workpiece C1.

[0065] Furthermore, in this embodiment, there are ninety-six through holes 212 provided inside the supporting member 21, arranged in six columns and sixteen rows. There are also ninety-six abutting heads 222 on the top plate, and each abutting head 222 corresponds to a through hole 212. Each abutting head 222 passes through the corresponding through hole 212 and then abuts against the side of the material carrier plate C2 away from the workpiece C1. Of course, in other embodiments, the number of the abutting heads 222 can be less than the number of the through holes 212, and the specific numbers of the through holes 212 and the abutting heads 222 can be set according to the specific situation.

[0066] In summary, the misaligned pressing mechanism 1000 of the present application can position the workpiece C1 installed on the material loading plate C2 by positioning the material loading plate C2. The pressing member 1 of the misaligned pressing mechanism 1000 abuts against one side of the material loading plate C2 adjacent to the workpiece C1, and the abutting mechanism 2 of the misaligned pressing mechanism 1000 abuts against the side of the material loading plate C2 away from the workpiece C1. The driving device 23 of the abutting mechanism 2 drives the supporting member 21 and the abutting member 22. The supporting member 21 and the abutting member 22 can abut against different regions on the side of the material loading plate C2 away from the workpiece C1 either successively or simultaneously or at the same time. The supporting member 21 and the abutting member 22 can generate displacements with different magnitudes relative to the pressing member 1, which can eliminate the gaps between the material loading plate C2 and the pressing member 1, between the material loading plate C2 and the supporting member 21, and between the material loading plate C2 and the abutting member 22, ensuring that different regions of the material loading plate C2 can be reliably pressed, and enabling good positioning of the workpiece C1 installed on the material loading plate C2.

[0067] The embodiment of the present application further provides a processing device, and the processing device includes the misaligned pressing mechanism 1000 described above. Due to the use of the misaligned pressing mechanism 1000 of the present application, the processing device can reliably press the material loading plate C2 on which the workpiece C1 is installed, realize good positioning of the workpiece C1 installed on the material loading plate C2, and ensure good processing quality of the workpiece C1. Obviously, the processing device of the present application can perform processing such as ultrasonic welding of LED devices.

[0068] The embodiment of the present application further provides a method for processing a workpiece. Using the processing device as described above, the method for processing a workpiece includes the following steps:

[0069] Transport the material loading plate C2 carrying the workpiece C1 between the pressing member 1 and the abutting mechanism 2 so that the workpiece C1 is aligned with the avoidance opening 11;

[0070] Control the pressing member 1 to move towards the side of the material loading plate C2 adjacent to the workpiece C1, control the supporting member 21 and the abutting member 22 to move towards the side of the material loading plate C2 away from the workpiece C1, control the pressing member 1 and the supporting member 21 to abut against the material loading plate C2 simultaneously to improve the positioning efficiency. After the supporting member 21 abuts against the side of the material loading plate C2 away from the workpiece C1, keep the pressing member 1 and the supporting member 21 stationary, control the abutting member 22 to continue moving towards the side of the material loading plate C2 away from the workpiece C1, and control the abutting member 22 and the supporting member 21 to abut against different regions on the side of the material loading plate C2 away from the workpiece C1 until both the side of the material loading plate C2 adjacent to the workpiece C1 and the side away from the workpiece C1 are pressed, so as to eliminate the gaps between the material loading plate C2 and the pressing member 1, between the material loading plate C2 and the supporting member 21, and between the material loading plate C2 and the abutting member 22;

[0071] Control the processing head of the processing device to enter the avoidance opening 11 to process the workpiece C1;

[0072] After the workpiece C1 is processed, control the pressing member 1 to leave the side of the loading plate C2 adjacent to the workpiece C1, and control the supporting member 21 and the abutting member 22 to leave the side of the loading plate C2 away from the workpiece C1;

[0073] Control the loading plate C2 to leave the space between the pressing member 1 and the abutting mechanism 2.

[0074] Through this method, the workpiece C1 installed on the loading plate C2 can be well positioned and processed, avoiding the influence of the uncompressed loading plate C2 on the processing quality of the workpiece C1. Obviously, using the workpiece processing method of the present application, processing such as ultrasonic welding of LED devices can be performed.
