Description

Technical Field

[0001] This utility model relates to the field of sign welding technology, specifically to a welding stud conveying mechanism for sign welding. Background Technology

[0002] In the process of steel production and sales, steel is generally sold in batches of bars. In order to mark the product information of the steel, a nameplate needs to be welded on each batch of steel.

[0003] Currently, signs are typically attached to welding studs by punching holes, and then the studs are welded to the steel using manual labor or automated equipment such as welding robots. Manual welding is inefficient, and existing technologies often utilize welding stud delivery equipment in conjunction with welding robots to complete the sign welding process.

[0004] For example, Chinese patent application CN115351398A discloses a robotic system for welding labels on bundled bars. This robotic welding system includes a label preparation device, a machine vision device, a label welding device, a stud conveying device, and a welding machine. The machine vision device faces the end face of the bundled bars to be labeled, and its signal output is connected to the controller of the label welding device. The label welding device includes an industrial robot and a stud clamping mechanism and a label picking device installed at the end of the industrial robot. The stud output of the stud conveying device is located at the stud picking position of the stud clamping mechanism, and the label output of the label preparation device is located at the label picking position of the label picking device. The welding machine is connected to the stud clamping mechanism via a cable. This equipment can realize automated welding of bar labels.

[0005] However, the above-mentioned device also has certain drawbacks: in order to ensure that the welding robot can accurately grasp the welding studs after they are conveyed by the conveying device, and to ensure the stability of the welding studs' posture while waiting to be grasped, the welding stud conveying device of the above-mentioned robot welding system is equipped with a nail clamping device at the end of the nail picking channel. The nail clamping device includes a gripper for gripping the nails, a cylinder for driving the gripper, a cylinder for moving the nail clamping device, and a guide rail, etc., which is relatively complex in structure. This undoubtedly increases the manufacturing and maintenance costs of the sign robot welding system. Utility Model Content

[0006] This utility model provides a welding stud conveying mechanism for sign welding, in order to solve the technical problem of high manufacturing and maintenance costs of existing welding stud conveying devices.

[0007] To solve the above problems, the present invention provides a welding stud conveying mechanism for sign welding, which adopts the following technical solution:

[0008] A stud feeding mechanism for sign welding includes a stud feeding channel, a stud feeding structure, and a controller. The stud feeding structure includes a slide rail, a cylinder, a stud feeding block, and a positioning device. The slide rail extends in the left-right direction and is perpendicular to the stud feeding channel. The stud feeding block is slidably mounted on the slide rail and has a stud receiving groove at its upper end. The stud feeding block is used to pick up studs and feed them to a predetermined position. The cylinder is located at the left end of the slide rail and is used to drive the stud feeding block to move back and forth left and right. The positioning device is used to detect the position of the stud feeding block and feed it back to the controller.

[0009] This utility model discloses a welding stud conveying mechanism for sign welding. By setting a stud receiving groove on the feeding block, a sensing block can receive welding studs conveyed by the feeding channel. After the positioning device detects the welding stud, a controller controls a cylinder to drive the feeding block along a slide rail to a predetermined position, thus completing the welding stud conveying. The receiving groove maintains the stability of the welding stud on the feeding block while receiving it. Compared with existing conveying devices, this welding stud conveying mechanism uses a receiving groove instead of grippers and a cylinder to push the receiving block to achieve welding stud conveying. Its structure is simple, and it can achieve the same function while reducing the manufacturing and maintenance costs of the conveying device.

[0010] Furthermore, the feeding block includes a feeding block body and a receiving block. The receiving block is installed at the rear end of the feeding block body. The receiving groove is a stepped U-shaped groove that is wider at the top and narrower at the bottom with the opening facing backward. The receiving groove is composed of an upper limit groove located on the feeding block body and a lower limit groove located on the receiving block. The bends of the upper limit groove and the lower limit groove are located on the same axis so as to support the welding stud through the upper surface of the receiving block.

[0011] Furthermore, the nail-attaching block is made of magnetic material to attract and attach welding nails delivered to the nail-attaching groove.

[0012] Its beneficial effect is that by setting the connector block to a magnetic material, the welding stud can be magnetically attracted to the upper surface of the connector block when it moves from the conveying channel to the connector slot, thereby further enhancing the stability of the welding stud's posture during subsequent conveying.

[0013] Furthermore, the connecting block is fixed in the mounting groove by screws.

[0014] Furthermore, the positioning device includes a photoelectric sensor fixed on the slide rail and a sensing block installed on the left end of the feeding block. The photoelectric sensor is located at the upper end of the feeding block and corresponds to the position of the feeding channel in the left-right direction. The sensing block is used to cooperate with the photoelectric sensor to detect the moving position of the feeding block.

[0015] Furthermore, the left end of the feeding block has a sliding groove extending to the left and right, and the sensing block is a rectangular block made of magnetic material. The sensing block is magnetically attracted in the sliding groove so that the moving distance of the feeding block can be adjusted by adjusting the position of the sensing block in the sliding groove.

[0016] Furthermore, the controller is a PLC controller, and the PLC controller is electrically connected to the photoelectric sensor and the cylinder.

[0017] The beneficial effects of the welding stud conveying mechanism for sign welding provided by this utility model are:

[0018] 1. The welding stud conveying mechanism for sign welding of this utility model has a stud receiving groove on the feeding block, which allows the sensing block to receive the welding studs conveyed by the feeding channel. After the positioning device detects the welding stud, the controller controls the cylinder to drive the feeding block to move along the slide rail to a predetermined position, thereby completing the conveying of the welding stud. The receiving groove can maintain the stability of the welding stud on the feeding block while receiving it. Compared with existing conveying devices, this welding stud conveying mechanism uses a receiving groove instead of a gripper and a cylinder to push the receiving block to achieve the conveying of the welding stud. The structure is simple and can reduce the manufacturing and maintenance costs of the conveying device while achieving the same function.

[0019] 2. By setting the connector block to a magnetic material, the welding stud can be magnetically attracted to the upper surface of the connector block when it moves from the conveying channel to the connector slot, thereby further enhancing the stability of the welding stud's posture during subsequent conveying.

[0020] 3. The design of the sensing block and the chute allows the operator to adjust the moving distance of the nail feeding block by adjusting the position of the sensing block on the nail feeding block, thus enhancing the applicability of the welding nail conveying mechanism.

[0028] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.

[0029] Embodiment 1 of the welding stud conveying mechanism for sign welding provided by this utility model:

[0030] like Figures 1 to 6 As shown, the stud feeding mechanism for sign welding includes a stud feeding channel 1, a stud feeding structure 2, and a controller. The stud feeding channel 1 extends in the front-to-back direction and is used to output studs 3. Its rear end is connected to a stud 3 feeding device. The stud feeding structure 2 is used to receive studs 3 and transport them to a designated position. The controller is used to control the stud feeding structure 2.

[0031] The following section first introduces the staple feeding channel 1, such as... Figure 1 and Figure 5 As shown, the feeding channel 1 is a rectangular block structure with an upward-facing conveying channel 11 inside. The cross-sectional shape of the conveying channel 11 matches the shape of the welding nail 3. The difference between the width of the channel and the outer surface of the welding nail 3 is two millimeters to ensure the smooth movement of the welding nail 3 within the conveying channel 11.

[0032] The following describes the second type of nail feeding structure, such as... Figures 1 to 4 As shown, the nail feeding structure 2 includes a slide rail 21, a driving device, a nail feeding block 23, and a positioning device 24. The slide rail 21 is a rectangular block structure extending left and right, and the upper side of the slide rail 21 has a rectangular guide groove 211 extending left and right. The nail feeding block 23 includes a nail feeding block body 231 and a nail receiving block 232. The nail feeding block body 231 is a rectangular block extending left and right, and the lower end of the nail feeding block body 231 has a rectangular guide block 231d extending left and right. The guide block 231d is slidably installed in the guide groove 211 so that the nail feeding block body 231 slides left and right on the slide rail 21.

[0033] The receiving block 232 is a rectangular magnet block. The receiving block 232 has a rearward-opening U-shaped lower limiting groove 233. The rear side of the upper end of the feeding block body 231 has a rearward-opening U-shaped upper limiting groove 231b. The lower end of the upper limiting groove 231b has a rearward-opening rectangular mounting groove 231a. The receiving block 232 is installed in the mounting groove 231a and fixed with screws. The bends of the upper limiting groove 231b and the lower limiting groove 233 are coaxially aligned, and the radius of the bend of the upper limiting groove 231b is larger than the radius of the bend of the lower limiting groove 233. The upper limiting groove 231b and the lower limiting groove 233 together form a receiving groove, which is used to receive the welding studs 3 conveyed by the feeding channel 1. The receiving block 232 has a receiving position for receiving the welding studs 3 and a releasing position for cooperating with the welding robot to pick up the welding studs 3. The driving device is used to drive the feeding block 232 to reciprocate between the receiving position and the releasing position.

[0034] The driving device is a cylinder 22, with the right end of the cylinder 22 being the output end. The cylinder 22 is fixed to the left end of the slide rail 21, and the output end of the cylinder 22 is fixedly connected to the left end of the nail feeding block 23, so that the nail feeding block 23 moves left and right along the slide rail 21 under the drive of the cylinder 22.

[0035] The positioning device 24 includes a fixed frame 242, a photoelectric sensor 241, and a sensing block 243. The fixed frame 242 is an L-shaped plate with its opening facing downwards. It is fixed to the front side of the slide rail 21 by bolts and is arranged in the left-right direction corresponding to the nail feeding channel 1. The photoelectric sensor 241 is mounted on the fixed frame 242 and is used to sense the welding nail 3 when the nail receiving block 232 is in the receiving position and to detect the sensing block 243 when the nail receiving block 232 is in the releasing position. The sensing block 243 is a rectangular magnet. The left end of the upper surface of the nail feeding block 23 has a left-right extending groove 231c. The sensing block 243 is magnetically attracted in the groove 231c and is used to adjust the moving distance of the nail feeding block 23 on the slide rail 21.

[0036] The controller is described below. It is a PLC controller. The controller is connected to the cylinder 22, the photoelectric sensor 241 and the welding nail 3 feeding device by wires to realize the automatic control of the welding nail 3 conveying mechanism.

[0037] The working principle of the welding stud conveying mechanism for sign welding is summarized as follows:

[0038] First, the welding stud 3 is conveyed from back to front on the feeding channel 1 by the welding stud 3 feeding device. The feeding block 23, which is in the receiving position, receives the welding stud 3 through the receiving slot and adsorbs it into the receiving slot through the receiving block 232. Then, the photoelectric sensor 241 detects the welding stud 3 and feeds it back to the controller. The controller controls the cylinder 22 to drive the feeding block 23 to move to the right to the release position. At this time, the photoelectric sensor 241 detects the sensing block 243, and the controller controls the feeding block 23 to stay in the release position for a certain time. At the same time, the welding robot picks up the welding stud 3. After the welding stud 3 is picked up, the controller controls the feeding block 23 to return to the receiving position to the left through the cylinder 22.

[0039] Embodiment 2 of the welding stud conveying mechanism for sign welding provided by this utility model:

[0040] Its main difference from Example 1 is:

[0041] In Example 1, the position detection of the feeding block is achieved by setting a photoelectric sensor for detecting the welding studs and the sensing block.

[0042] In this embodiment, there are two photoelectric sensors, both of which are fixed on the slide rail and correspond to the receiving position and the releasing position of the pin slot, respectively.
