Description

Technical Field

[0001] The utility model relates to the field of screw driving devices, in particular to screw driving equipment. Background Art

[0002] During assembly line processing, various types of screw driving equipment are often used. Due to the diverse product shapes and connection methods, the requirements for screw driving equipment are also different. Take lighting fixtures as an example. In addition to the screwing requirements on the top and bottom, the sides of lighting fixtures often also require screwing for fastening. However, the space on the sides of the lighting fixtures is limited, and the points requiring screwing are relatively dense. It is impossible to concentrate all the large-diameter screw drivers in such a small space. Therefore, existing production lines generally use a single screw driver or a batch screwing method. This is significantly different from the ideal method of driving all the screws at once, seriously affecting processing efficiency. Utility Model Content

It should be noted that a person skilled in the art may make various variations and improvements without departing from the scope of the present invention. Such variations and improvements are all within the scope of protection of the present invention.

[0039] This embodiment includes: a mounting frame 1, a mobile workstation 2, a mobile screw driving assembly 3 and a pressing assembly 4; wherein the mounting frame 1 includes: a lower mounting plate 101, a first slide rail 102, a support frame 103 and an upper mounting frame 104; the mobile workstation 2 includes: a first base plate 201, a second slide rail 202, a fixture mounting plate 203 and a fixture 204; the mobile screw driving assembly 3 includes: a second base plate 301, a first cylinder 302, a screw driving machine motor 30 3. First positioning frame 304, universal joint 305, fixing block 306, screw machine mounting nozzle 307, second positioning frame 308 and third slide rail 309; the pressing assembly 4 includes: pressing plate 401, fixing plate 402, connecting plate 403, connecting rod 404, sleeve 405, floating joint 406, second cylinder mounting plate 407, second cylinder 408, third cylinder 409, first lifting plate 410, second lifting plate 411 and fastening gap 412.

[0040] like Figure 1 As shown, the support frame 103 is welded from multiple steel sections and is divided into two layers, the lower layer being mounted with a horizontally arranged lower mounting plate 101, and the upper layer being mounted with a horizontally arranged upper mounting frame 104. The upper mounting frame 104 is located directly above the lower mounting plate 101. A first slide rail 102 is horizontally arranged on the upper side of the lower mounting plate 101, and a fourth slide rail is horizontally arranged on the lower side of the upper mounting frame 104. The movable work station 2 and the movable screw driving assembly 3 are slidably mounted on the lower mounting plate 101 via the first slide rail 102. The pressing assembly 4 is slidably mounted on the upper mounting frame 104 via the fourth slide rail, and the pressing assembly 4 is located downwardly from the upper mounting frame 104. A movable screw driving assembly 3 is provided on each side of the movable work station 2 along the moving direction of the first slide rail 102, for driving screws on both sides of the lighting fixture.

[0041] like Figure 2 As shown, a second slide rail 202 is horizontally arranged on the first base plate 201, and the extension direction of the second slide rail 202 is perpendicular to the first slide rail 102. The fixture mounting plate 203 is slidably mounted on the first base plate 201 through the second slide rail 202, and the fixture 204 is mounted on the fixture mounting plate 203.

[0042] like Figure 3 As shown, a horizontally mounted first cylinder 302 and a third slide rail 309 are mounted on the second base plate 301. A first positioning frame 304 and a second positioning frame 308 are slidably mounted on the second base plate 301 via the third slide rail 309. The first positioning frame 304 and the second positioning frame 308 are connected by screws, and the spacing between them can be adjusted during installation. The first cylinder 302 pushes the first positioning frame 304, which in turn drives the second positioning frame 308 to slide along the third slide rail 309. The first positioning frame 304 is provided with multiple first positioning holes for mounting screw driver motors 303. The spacing between the multiple first positioning holes is large, providing space for mounting multiple screw driver motors 303. The second positioning frame 308 is transversely provided with a movable slot, through which multiple fixing blocks 306 are mounted on the second positioning frame 308. The fixing blocks 306 are longitudinally provided with multiple second positioning holes for mounting screw driver nozzles 307. The fixing block 306 can move laterally along the movable slot, providing different lateral positions for the screw driver mounting nozzle 307. Furthermore, the screw driver mounting nozzle 307 can select different second positioning holes based on the required longitudinal position. The screw driver motor 303 is connected to the screw driver mounting nozzle 307 via a universal joint 305, which ensures torque transmission to the screw driver mounting nozzle 307 even when the axes are not aligned.

[0043] In this embodiment, the screw driving machine motor 303 is used to provide torque, and the screw driving machine installation nozzle 307 adopts a hollow pipe with a built-in screw driving head and is connected to the material trough through a hose on the side. After the screw moves to the hollow pipe of the screw driving machine installation nozzle 307 through the hose, the screw driving head pushes the screw out and transmits torque to the screw to tighten the screw.

[0044] like Figure 4As shown, the first hanging plate 410 can slide along the fourth slide rail to adjust its position, but needs to be fixed when in use. The second hanging plate 411 is slidably installed on the bottom side of the upper mounting frame 104 through the fourth slide rail, and is pushed by the third cylinder 409 installed on the first hanging plate 410; one end of the four vertically arranged connecting rods 404 is installed on the second hanging plate 411, and the other end is fixed by the fixing plate 402. On the one hand, the fixing plate 402 can limit the connecting plate 403, and on the other hand, it can fix the ends of the four connecting rods 404 to prevent displacement. The second cylinder mounting plate 407 is fixedly mounted on the connecting rod 404, a connecting plate 403 is arranged between the second cylinder mounting plate 407 and the fixed plate 402, the connecting plate 403 is slidably mounted on the connecting rod 404, the second cylinder 408 is mounted on the second cylinder mounting plate 407 and pushes the connecting plate 403 to slide, the lower pressing plate 401 is connected to the connecting plate 403 through a rod and is arranged on the side of the fixed plate 402 facing away from the connecting plate 403, the function of the lower pressing plate 401 is to flatten the products that are not flattened.

[0045] like Figure 5 As shown, in one embodiment, a through hole for the connecting rod 404 to pass through is provided on the second cylinder mounting plate 407, and a fastening gap 412 is provided between the through hole and the edge of the second cylinder mounting plate 407; the fastening gap 412 divides the second cylinder mounting plate 407 part on the side of the through hole into two parts, and there is a gap between the two parts. At the same time, a screw hole is provided to match the screw to connect the two parts. When the screw is tightened, the gap becomes smaller and the through hole is tightened a little, thereby fixing it to the connecting rod 404.

[0046] In one embodiment, sleeves 405 are installed at the four corners of the connecting plate 403, the sleeves 405 are mounted on the connecting rod 404 and a gap is set, and the connecting plate 403 is slidably connected to the connecting rod 404 through the sleeves 405; at the same time, the second cylinder 408 is connected to the connecting plate 403 through the floating joint 406, so that when the lower pressure plate 401 contacts the product, there is a tilting margin, which can better contact with the upper surface of the product.

[0047] In one embodiment, two sets of jig mounting plates 203 and jigs 204 are provided. During processing, operators are located at workstations on either side of the mounting frame 1. Specifically, while the product on the jig 204 on one side is being screwed, the operator at the other workstation can remove the finished product and place a new one. After screwing is completed, the product is removed via the second slide rail 202 and the operator can operate it. The product to be screwed is then moved to the mobile screwing assembly 3 for screwing. This creates a dual-station processing system, improving work efficiency.

[0048] In one embodiment, two sets of independently arranged first positioning frames 304, second positioning frames 308 and first cylinders 302 are provided on the second base plate 301 on each side, and are equipped with independent third slide rails 309, so as to enable each set of first positioning frames 304 and second positioning frames 308 to move independently, thereby adapting to the unevenness of the screw-driving area on the side.

[0049] In one embodiment, the slider and the slide rail can be matched to slide under the thrust of the cylinder. Other linear movement methods can also be used, such as a motor driving a screw nut pair.
