The positioning cover 320 is provided with a positioning hole 321. The positioning cover 320 is aligned with the placement fixture 200. When the placement fixture 200 slides to be aligned with the positioning cover 320, the positioning cover 320 moves in the direction close to the placement fixture 200. The positioning hole 321 is connected to the placement cavity 201. The locking mechanism 400 is used to pass through the positioning hole 321 to lock the screws of the product to be processed placed in the placement cavity 201.

[0028] In this embodiment, the product to be processed is placed in the placement cavity 201 of the placement jig 200. By sliding the placement jig 200 on the mounting plate 110, the product to be processed can be driven to be located under the positioning cover plate 320. The first driver 310 drives the positioning cover plate 320 to move in the direction close to the placement jig 200, so that the positioning cover plate 320 is covered on the placement jig 200. The positioning hole 321 on the positioning cover plate 320 is connected to the placement cavity 201 of the placement jig 200, and the positioning hole 321 is aligned with the threaded hole on the product to be processed. In this way, when the locking mechanism 400 locks the screw of the product to be processed placed in the placement cavity 201, the positioning hole 321 can play a role of limiting abutment, so that the locking mechanism 400 after passing through the positioning hole 321 can be accurately aligned with the locking area, that is, the locking mechanism 400 can be accurately aligned with the threaded hole on the product to be processed, thereby effectively locking the screw placed in the threaded hole.

[0029] In one embodiment, Figure 1 and Figure 2As shown, the locking mechanism 400 includes: a mounting frame 410, a first slide 420, a second slide 430, a second driver 440 and a locking member 450, the mounting frame 410 is set on the workbench 100, the first slide 420 is slidably set on the mounting frame 410, the second slide 430 is slidably set on the first slide 420, the sliding direction of the first slide 420 on the mounting frame 410 and the sliding direction of the second slide 430 on the first slide 420 are perpendicular to each other, the locking member 450 is rotatably set on the second slide 430, the second driver 440 is set on the second slide 430, and the second driver 440 is driven and connected to the locking member 450. Specifically, the locking member 450 is a screwdriver, the sliding direction of the mounting plate 110 on the workbench 100 is the X-axis direction, the sliding direction of the first slide 420 on the mounting frame 410 is the Y-axis direction, and the sliding direction of the second slide 430 on the first slide 420 is the Z-axis direction. The mounting plate 110 slides on the workbench 100 to adjust the relative position between the placement fixture 200 and the locking member 450 in the X-axis direction, that is, to adjust the relative position of the locking member 450 and the threaded hole of the product to be processed in the X-axis direction, and cooperate with the locking member 450 to move in the Y-axis direction and the Z-axis direction, so that the position of the locking member 450 can be adjusted in the three-axis direction, and further through the guiding effect of the positioning hole 321, the screws in the threaded hole of the product to be processed can be accurately locked, and at the same time, the locking member 450 can also be used to lock the screws in different threaded holes of the product to be processed.

[0030] In one embodiment, Figure 3 As shown, the placement fixture 200 includes: a base plate 210, a placement plate 220 and a plurality of connecting rods 230, the base plate 210 is slidably arranged on the mounting plate 110, the first end of each connecting rod 230 is connected to the base plate 210, and the second end of each connecting rod 230 is connected to the placement plate 220, the placement plate 220 and the base plate 210 are spaced apart to form the placement cavity 201, and a placement opening 202 is opened on the placement plate 220, and the placement opening 202 is connected to the placement cavity 201. Specifically, the number of connecting rods 230 is set to four, the first ends of the four connecting rods 230 are distributed at the four corners of the base plate 210, and the second ends of the four connecting rods 230 are distributed at the four corners of the placement plate 220. The product to be processed is placed between the placement plate 220 and the base plate 210 through the placement port 202, that is, placed in the placement cavity 201. The locking piece 450 passes through the positioning hole 321 and the placement port 202 in turn to lock the screws in the threaded hole of the product to be processed in the placement cavity 201.

[0031] In one embodiment, the automatic screw locking device 10 further includes: a top plate, a plurality of guide holes are provided on the top plate, the top plate is sleeved on the connecting rod 230 through the guide holes, and the top plate moves in the direction close to or away from the placement plate 220. Specifically, the top plate is slidably arranged on each connecting rod 230 and is located between the bottom plate 210 and the placement plate 220. After the locking member 450 locks the screws in the threaded hole of the product to be processed, the top plate moves in the direction close to the placement plate 220, that is, the top plate moves upward, which can lift up the processed product, making it easier for the operator to take out the processed product. It is worth noting that the method of driving the top plate to move upward to lift up the processed product is a method that can be known to those skilled in the art and is achievable. In this embodiment, no cumbersome description is given. For example, driving the top plate to move upward is achieved by setting an electric push rod.

[0032] In one embodiment, two limit blocks are spaced apart on the positioning cover plate 320, and each of the limit blocks is movably abutted against the outer surface of the placement plate 220. Specifically, the two limit blocks are spaced apart on the side of the positioning cover plate 320 facing the placement plate 220. When the positioning cover plate 320 is covered on the placement jig 200, the two limit blocks are respectively abutted against the two ends of the placement plate 220, that is, the placement plate 220 is located between the two limit blocks, which can limit the relative position between the positioning cover plate 320 and the placement jig 200, so that the directional hole on the positioning cover plate 320 can be accurately aligned with the threaded hole of the product to be processed in the placement cavity 201, so that the locking member 450 can accurately lock the screw in the threaded hole of the product to be processed.

[0033] In one embodiment, Figure 3 As shown, the placement plate 220 is provided with an abutment block 500, which is in movable abutment with the positioning cover plate 320. Specifically, the number of abutment blocks 500 is set to two, and the two abutment blocks 500 are spaced apart on the side of the placement plate 220 facing the positioning cover plate 320, which can limit the movement distance of the positioning cover plate 320, that is, the relative position between the positioning cover plate 320 and the placement plate 220 can be limited, and can avoid excessive abutment between the positioning cover plate 320 and the product to be processed in the placement cavity 201. Furthermore, a buffer layer is provided on the abutment block 500, and the buffer layer is a silicone layer or a rubber layer, which can effectively play a buffering role and protect the positioning cover plate 320.

[0034] In one embodiment, the positioning cover plate 320 has a limiting groove defined on a surface facing the placement jig 200. Specifically, when the positioning cover plate 320 is placed on the placement jig 200, the product to be processed in the placement cavity 201 is at least partially located within the limiting groove, further serving as a limiting guide. The directional holes in the positioning cover plate 320 can be more accurately aligned with the threaded holes of the product to be processed in the placement cavity 201, thereby enabling the locking member 450 to be more accurately aligned with the threaded holes of the product to be processed, thereby better tightening the screws placed in the threaded holes.

[0035] In one embodiment, Figure 3 As shown, the width of the positioning hole 321 gradually increases from the end closest to the mounting fixture to the end further away from the mounting fixture. Specifically, the width of the positioning hole 321 at the end facing the locking member 450 is greater than the width of the positioning hole 321 at the end facing the placement plate 220. This facilitates the locking member 450 to enter the positioning hole 321. After passing through the positioning hole 321, the locking member 450 can effectively lock the screw placed in the threaded hole.

[0036] In one embodiment, Figure 1 As shown, the mounting plate 110, the placement jig 200, and the positioning assembly 300 are provided in two sets. Specifically, by providing two sets of mounting plates 110, placement jigs 200, and positioning assemblies 300, the operator can conveniently place the products to be processed into the placement cavities 201 of the two placement jigs 200 in sequence. The locking member 450 can continuously tighten the screws in the threaded holes of different products to be processed, thereby improving processing efficiency.

[0037] Compared with the prior art, the present invention has at least the following advantages:

[0038] The present invention provides an automatic screw-locking device that places the product to be processed in the placement cavity of a placement jig, slides the placement jig on the mounting plate to align it with the positioning cover, and then a first driver drives the positioning cover to move toward the placement jig, so that the positioning cover is placed on the placement jig, and the positioning holes on the positioning cover are connected to the placement cavity of the placement jig. Through this arrangement, when the locking mechanism locks the screws of the product to be processed placed in the placement cavity, the positioning holes can act as a limiting abutment, allowing the locking mechanism, after passing through the positioning holes, to accurately align with the locking area, thereby effectively locking the screws.
