Description

Technical Field

[0001] The utility model relates to the technical field of drawer slide rail processing equipment, in particular to a pick welding device for a drawer slide rail. Background Art

[0002] Drawer slides are common sliding components used in daily life and industry. In modern furniture design, drawers are an important part of storage space. Drawer slides can provide stable support and guidance, ensuring that drawers move smoothly on linear tracks and achieve smooth and low-noise opening and closing of drawers.

[0003] The classification of drawer slides mainly includes: side-mounted slides, bottom-mounted slides, riding slides and concealed slides, etc. Each slide has its own unique structure and applicable scenarios. Among them, side-mounted slides and bottom-mounted slides are the most common types, and riding slides are widely used in heavy drawers and occasions requiring full extension functions due to their special structural design. For example, the Chinese patent with announcement number CN212938856U discloses a drawer guide with a buffer device, including a fixed slide and a movable slide movably connected thereto. A fixed bracket is provided on the outer side of the fixed slide, and a damping groove for placing a damper and a spring groove for placing a tension spring are provided on the fixed bracket. The support rod of the damper is connected to a movable slider, and the movable slider is slidably connected to the fixed bracket along the length direction of the fixed slide. The movable slider is transmission-connected with a paddle, which is fixedly connected to the movable slide. One end of the tension spring is fixedly connected to the fixed bracket, and the other end is connected to the movable slider. The movable slide is abutted against the damper by the paddle to buffer the movable slide, thereby achieving buffering of the drawer.

[0004] In the prior art, resistance welding is used to weld the paddle and the movable slide rail. The operator places the movable slide rail on the welding station, then places the paddle on the movable slide rail, starts the welding device, and presses the pressure block down on the paddle to achieve welding of the paddle. With respect to the above-mentioned related technologies, the inventor believes that there are the following defects: in mass production, since the operator manually places the paddle and the movable slide rail, there will be slight differences in the placement position each time, resulting in poor welding consistency, and the strength and appearance of each weld may be different, affecting product quality; secondly, the operator needs to operate the welding equipment at close range, and strong arc and spatter will be generated during the resistance welding process. The operator may be injured by the arc or spatter, and there is a certain safety risk; thirdly, the degree of automation is low, and each welding requires the operator to complete a series of actions such as placement, adjustment and welding, resulting in low production efficiency and not suitable for large-scale production.

[0037] Example 1: Figure 1-10 As shown, a pick welding device for a drawer slide includes a base 1, which is equipped with a welding mechanism 2 for welding the pick and the movable slide, a conveying mechanism 3 for conveying the movable slide, and a loading mechanism 4 for conveying the pick to the movable slide. The welding mechanism 2 and the loading mechanism 4 are both located at one end of the movable slide. The welding mechanism 2 includes a support seat 201, and the support seat 201 is provided with a limiting groove 2011 with an opening facing the movable slide. The inner wall of the limiting groove 2011 is adapted to the outer wall of the movable slide, and the bottom wall of the groove is in the same plane as the bottom wall of the movable slide on the conveying mechanism 3. The base 1 is also equipped with a pushing mechanism 5, which is used to push the movable slide on the conveying mechanism 3 to move back and forth toward the limiting groove 2011, and the pushing mechanism 5 is located at the other end of the movable slide.

[0038] When the paddle welding device is in operation, the movable slide rail is placed on the conveying mechanism 3, and the paddle is prevented from being on the loading mechanism 4. The conveying mechanism 3 moves to convey the movable slide rail to between the welding mechanism 2 and the pushing mechanism 5. The pushing mechanism 5 pushes the movable slide rail into the limiting groove 2011 of the support seat 201. The limiting groove 2011 plays a limiting role on the movable slide rail. The loading mechanism 4 conveys the paddle to the movable slide rail, and the welding mechanism 2 welds the contact point between the paddle and the movable slide rail. After the welding is completed, the pushing mechanism 5 drives the movable slide rail to move away from the support seat 201, and then the conveying mechanism 3 moves to convey the movable slide rail for unloading.

[0039] By providing a welding mechanism 2, a loading mechanism 4, a conveying mechanism 3, and a pushing mechanism 5, the problems of tedious steps for operators to manually place the picks and poor welding consistency are solved, the degree of production automation is improved, manual operation errors are reduced, welding quality and product consistency are improved, and the product repair rate and scrap rate due to poor welding are reduced. By providing a support seat 201 with a limited groove 2011, the precise positioning of the pick and the movable slide rail is ensured, thereby improving the welding accuracy and reducing the deviation of the welding position. In conjunction with the pushing mechanism 5, the precise movement of the movable slide rail during the welding process is realized, the welding stability is improved, and welding defects caused by unstable movement are reduced. Secondly, automated welding is achieved through the pick welding device, which reduces the contact between the operator and the welding equipment, improves operational safety, and reduces the risk of injury to the operator from arc light and spatter.

[0040] In order to improve the limiting accuracy of the movable slide rail when welding the movable slide rail and the pick, thereby improving the consistency of the pick welding quality, the welding mechanism 2 includes a pressure block 202 and a positioning cylinder 203. The limiting groove 2011 is set in an L shape. The pressure block 202 is located just above the bottom wall of the limiting groove 2011, and the pressure block 202 moves back and forth toward the limiting groove 2011. The positioning cylinder 203 is located in the longitudinal axis direction of the support seat 201. The fixed end of the positioning cylinder 203 is connected to the machine base 1, and the push rod of the positioning cylinder 203 moves back and forth toward the side wall of the limiting groove 2011. It is worth mentioning that the pressure block 202 and the support seat 201 form a welding electrode, thereby realizing resistance welding of the pick and the movable slide rail. The pushing end of the positioning cylinder 203 is connected to a rubber insulating block to reduce the risk of leakage caused by conduction between the welding electrode and the positioning cylinder 203, thereby improving the safety performance of the equipment. The contact between the positioning cylinder 203 and the movable slide rail plays a buffering role. During operation, the movable slide rail is pushed into the limiting groove 2011 by the pushing mechanism 5. Since the limiting groove 2011 is L-shaped, the smoothness of the movable slide rail entering the limiting groove 2011 is improved, and the L-shape is adapted to the movable slide rail, so that the bottom wall and side walls of the limiting groove 2011 play a limiting role on the bottom wall and side walls of the movable slide rail. Start the positioning cylinder 203, the positioning cylinder 203 is located on the longitudinal side wall of the movable slide rail, and the push rod of the positioning cylinder 203 moves toward the side wall of the movable slide rail, pushing the movable slide rail to move until its other side wall contacts the inner wall of the limiting groove 2011, thereby completing the limiting of the movable slide rail. By adopting the welding mechanism 2 composed of the pressure block 202 and the positioning cylinder 203, and the design of the L-shaped limiting groove 2011, the limiting accuracy of the movable slide rail during the welding process is improved, and the consistency of the pick welding quality is improved.

[0041] In terms of the specific structure of the pressing block 202 moving back and forth toward the limiting groove 2011, the welding mechanism 2 also includes a pressing block cylinder 204 and a bracket 205. The bracket 205 is assembled with the machine base 1 and is located in the vertical axis direction of the support base 201. The fixed end of the pressing block cylinder 204 is connected to the bracket 205, and the pushing end of the pressing block cylinder 204 is connected to the pressing block 202. Through the configuration of the pressing block cylinder 204, the movement of the pressing block 202 toward the limiting groove 2011 is controlled, thereby improving the stability of the welding between the paddle and the movable slide rail and reducing welding defects.

[0042] In order to optimize the path of the paddle moving to the movable slide rail, the feeding mechanism 4 is located in the longitudinal direction of the support seat 201, and the positioning cylinder 203 is located between the feeding mechanism 4 and the support seat 201. In terms of the specific structure of the feeding mechanism 4 clamping the paddle and moving it to the movable slide rail, the feeding mechanism 4 is located in the longitudinal direction of the support seat 201. The feeding mechanism 4 includes a feeding seat 401, a longitudinal cylinder 402, a first clamping claw 403, and a first clamping claw cylinder 404. The feeding seat 401 is provided with a material trough 4011 for placing the paddle. The longitudinal cylinder 402 is assembled on the machine base 1 and is used to push the first clamping claw cylinder 404 moves back and forth toward the support seat 201. The first clamping jaw 403 is provided with two groups and is respectively connected to the clamping end of the first clamping jaw cylinder 404. The first clamping jaw 403 is used to clamp the paddle on the material trough 4011, realizing the automatic loading of the paddle, improving the efficiency of moving the paddle to the movable slide rail, reducing manual operation time, and improving the overall production speed. By setting the pushing stroke of the longitudinal movement cylinder 402, the paddle can be accurately placed on the movable slide rail, which helps to ensure the position accuracy of the paddle, reduces the paddle positioning error during welding, and improves the welding quality.

[0043] Furthermore, in order to improve the contact stability between the pick and the movable slide rail during welding, thereby ensuring welding accuracy, the feeding mechanism 4 also includes a stand 405, a vertical movement block 406, a vertical movement cylinder 407, and a longitudinal movement block 408. The stand 405 is vertically connected to the machine base 1, the vertical movement block 406 is slidably assembled with the stand 405 and slides along the vertical axis direction of the stand 405, the vertical movement cylinder 407 is assembled on the stand 405 and is used to push the vertical movement block 406 to slide, and the longitudinal movement block 408 is slidably assembled with the vertical movement block 406 and slides along the vertical axis direction of the stand 405. The longitudinal axis direction of the moving block 406 slides, the longitudinal cylinder 402 is connected to the vertical moving block 406 and is used to push the longitudinal moving block 408 to move, the fixed end of the first clamping cylinder 404 is connected to the longitudinal moving block 408, the fixed end of the vertical moving cylinder 407 is connected to the stand 405, the pushing end of the vertical moving cylinder 407 is connected to the vertical moving block 406, the fixed end of the longitudinal cylinder 402 is connected to the vertical moving block 406, the pushing end of the longitudinal cylinder 402 is connected to the longitudinal moving block 408, and the vertical moving block 406 and the stand 405 are connected. The sliding assembly is performed through the slide rail slider, and the longitudinal movement block 408 and the vertical movement block 406 are slidably assembled through the slide rail slider. The vertical movement cylinder 407 is provided to improve the movement freedom of the first clamping jaw 403. When clamping the pick, the vertical movement cylinder 407 controls the first clamping jaw 403 to move downward toward the loading seat 401 to clamp the pick. After the clamping is completed, the vertical movement cylinder 407 controls the first clamping jaw 403 to move upward, and the longitudinal movement cylinder 402 pushes the first clamping jaw 403 to move toward the movable slide rail on the support seat 201. The paddle moves to the top of the movable rail, and the paddle is pre-pressed on the top wall of the movable rail. Then the welding mechanism 2 performs welding. The position of the first clamping jaw 403 is controlled by the coordinated use of the vertical cylinder 407 and the longitudinal cylinder 402 to ensure the contact stability between the paddle and the movable rail, thereby improving the stability of the welding process, reducing the vibration during welding, and ensuring the welding accuracy.

[0044] Since the pick is set in an L shape, the material trough 4011 is adapted to the pick and its cross section is L-shaped in order to better limit the pick. The above-mentioned structural setting is not conducive to the first clamping jaw 403 taking out the pick from the material trough 4011. If the pick is moved to the material trough 4011 and then clamped by the first clamping jaw 403, the positioning effect of the material trough 4011 on the pick is reduced. In order to solve the above technical problems and realize the continuous clamping of the pick by the first clamping jaw 403, the feeding mechanism 4 also includes a vibration plate 409, a material stopper Block 410, the vibration plate 409 is used to directional sorting and conveying the picks, one end of the loading seat 401 is connected to the discharge port of the vibration plate 409 and is used to directional conveying the picks, the other end of the loading seat 401 is provided with a discharge groove, the discharge groove is located in the longitudinal direction of the loading seat 401 and is connected to the material trough 4011, the blocking block 410 is provided with an avoidance groove 4101 on one side facing the first clamping jaw 403, the blocking block 410 is slidably assembled with the discharge groove and is used to move the pick in the material trough 4011 toward the first clamping jaw 403, and the discharge groove The horizontal inner wall is adapted to the horizontal outer wall of the paddle. When the paddle slides out of the discharge port of the vibration disk 409 and enters the material trough 4011, the material trough 4011 is tilted so that the paddle slides down under the action of its own weight and slides into the avoidance groove 4101 of the blocking block 410. The movement of the blocking block 410 drives the paddle to move in the discharge trough. The inner side wall of the discharge trough limits the movement of the paddle, and the blocking block 410 brings the paddle into the discharge trough 4011. It should be noted that the vertical side wall of the paddle is close to the first clamping jaw 403. The vibration disk 409 can carry out directional sorting and conveying of the picks, ensuring that the picks enter the material trough 4011 in a uniform direction, thereby improving the loading accuracy and reducing operational errors. By setting the avoidance groove 4101 and the blocking block 410, the picks can be smoothly moved from the material trough 4011 to the position where the first clamping claw 403 can clamp them, solving the problem that the L-shaped picks are difficult to clamp directly, and improving the clamping efficiency. The inner wall of the discharge groove is adapted to the horizontal outer wall of the pick, so that the pick maintains its positioning effect during the sliding process, reducing the positioning error caused by movement.

[0045] In terms of the specific structure of the sliding assembly of the stop block 410 and the discharge trough, the feeding mechanism 4 also includes a stop cylinder 411. The stop block 410 is arranged in an inverted "T" shape, and the inner wall of the discharge trough is adapted to the outer wall of the stop block 410. The fixed end of the stop cylinder 411 is connected to the feeding seat 401, and the pushing end of the stop cylinder 411 is connected to the stop block 410. The adaptation design of the inverted "T"-shaped stop block 410 and the discharge trough improves the movement accuracy of the paddle in the trough 4011. The stop cylinder 411 controls the movement of the stop block 410 to ensure the smooth movement and accurate position of the paddle in the trough 4011, thereby improving the loading accuracy of the paddle when it moves to the bottom of the first clamp 403.

[0046] In terms of the specific structure of the first clamping jaw 403, the first clamping jaw 403 is bent from the clamping end of the first clamping jaw cylinder 404 toward the discharge slot, and the first clamping jaw 403 is provided with a clamping opening 4031. A guide slope is provided at the connection between the clamping opening 4031 and the side wall of the first clamping jaw 403. The setting of the guide slope helps to guide the paddle to smoothly enter the clamping opening 4031, reducing the resistance during the clamping process, so that the first clamping jaw 403 can clamp the paddle more smoothly, improve the clamping efficiency, and improve the accuracy of clamping. It is worth mentioning that in order to reduce the leakage of electrical energy during welding, the first clamping jaw 403 is provided with a rubber insulation layer, and the rubber insulation layer is provided on the clamping opening 4031, which is used to reduce the risk of electrical energy leakage when the first clamping jaw 403 clamps the paddle for welding, thereby improving the safety and welding quality of the paddle welding.

[0047] In terms of the specific structure of the conveying mechanism 3, the conveying mechanism 3 includes a fixed seat 301 and a movable seat 302. The top walls of the fixed seat 301 and the movable seat 302 are provided with several groups of limit grooves for placing the movable slide rails. When there are multiple groups of limit grooves, the limit grooves are arranged at equal intervals along the longitudinal direction of the fixed seat 301 and the movable seat 302 respectively. The fixed seat 301 is assembled on the machine base 1. The fixed seat 301 is provided with two groups and is respectively located at the two ends of the movable slide rail. The movable seat 302 is assembled with the machine base 1 for vertical and horizontal sliding. The movable seat 302 is provided with two groups and is located between the two groups of fixed seats 301. By providing limit grooves, a single group of movable slide rails is limited and supported. Under the vertical and horizontal sliding of the movable seat 302, the movable slider is driven to move longitudinally in sequence along the limit grooves of the fixed seat 301, thereby improving the moving accuracy of the movable slide rail and the stability of the movable slide rail transportation.

[0048] In terms of the specific structure of the pushing mechanism 5, the pushing mechanism 5 and the support seat 201 are arranged at both ends of the movable slide rail.

The top wall of the pushing block 502 is provided with a positioning groove 5021 adapted to the outer wall of the movable slide rail. The pushing cylinder 501 is connected to the connecting seat 503 and is used to push the pushing block 502 toward the support seat 201. The fixed end of the pushing cylinder 501 is connected to the connecting seat 503, and the pushing cylinder 501 and the pushing end are connected to the pushing block 502. The pushing block 502 and the connecting seat 503 are slidably assembled through the slide rail slider structure. Of course, the limiting groove at the corresponding pushing block 502 needs to be enlarged so that the pushing block 502 can slide smoothly to pass through the fixed seat 301, and the inner wall of the positioning groove 5021 of the pushing block 502 and the inner wall of the limiting groove on the other set of fixed seats 301 form a support for both ends of the moving slide rail.

[0049] In order to improve the moving accuracy of the pushing block 502, the pushing mechanism 5 also includes a guide block 504. A guide hole is opened on the side wall of the connecting seat 503. The guide block 504 is inserted into the guide hole and one end of the guide block 504 is connected to the pushing block 502. When the pushing cylinder 501 drives the pushing block 502 to move, the slide rail slider and the guide block 504 and the guide hole support and limit the movement of the pushing block 502, ensuring the moving accuracy of the movable slide rail, thereby improving the welding accuracy of the movable slide rail and the paddle.

[0050] Example 2: Figure 1-10 As shown, a left and right rail alternating loading device includes a machine base 1, the machine base 1 is equipped with a left conveying mechanism 6 for conveying the left movable slide rail, a right conveying mechanism 7 for conveying the right movable slide rail, and a transporting mechanism 3 for conveying the movable slide rail. The left conveying mechanism 6 and the right conveying mechanism 7 are arranged along the horizontal axis direction of the machine base 1, and the transporting mechanism 3 is located in the longitudinal axis direction of the left conveying mechanism 6. The transporting mechanism 3 includes a fixed seat 301 and a movable seat 302. The fixed seat 301 is assembled on the machine base 1, and the fixed seat 301 is connected to a receiving block 304 extending toward the left conveying mechanism 6. The receiving block 304 is used to receive the left movable slide rail on the left conveying mechanism 6 onto the fixed seat 301. The machine base 1 is also equipped with a transferring mechanism 8 for transporting the right movable slide rail on the right conveying mechanism 7 to the fixed seat 301. The movable seat 302 is movably assembled on the inner side of the fixed seat 301, and is used to drive the movable slide rail on the fixed seat 301 to move along the longitudinal axis direction of the machine base 1.

[0051] During operation, the left movable slide and the right movable slide after stamping are placed on the left conveying mechanism 6 and the right conveying mechanism 7 respectively. Of course, the method of paralleling the conveying lines or manually placing the materials can be used. It is preferred to parallel the conveying lines, but the paralleling structure is not the focus of improvement in this embodiment and will not be expanded here. When the left movable slide and the right movable slide are placed, the left movable slide moves toward the direction of the fixed seat 301. Under the push of the left conveying mechanism 6, the left movable slide is pushed to the receiving block 304 and then enters the conveying range of the moving seat 302. At the same time, the right movable slide is driven by the right conveying mechanism 7 and moves toward the direction of the transfer mechanism 8 After the transfer mechanism 8 clamps the right movable slide rail on the right conveying mechanism 7, it moves horizontally along the machine base 1, thereby placing the right slide rail on the fixed seat 301. At this time, since the transfer mechanism 8 and the receiving block 304 are staggered along the longitudinal direction of the machine base 1, the left movable slide rail and the right movable slide rail are longitudinally staggered on the fixed seat 301. Then, the moving seat 302 moves to drive the movable slide rail on the fixed seat 301 to move, thereby longitudinally transporting the longitudinally staggered left movable slide rail and right movable slide rail, thereby realizing the alternating loading of the left movable slide rail and the right movable slide rail in sequence. Of course, every time the moving seat 302 moves, the transfer mechanism 8 clamps a right movable slide rail and moves it to the fixed seat 301.

[0052] It should be noted that the left movable slide rail and the right movable slide rail are collectively referred to as movable slide rails. Through the left and right rail alternating loading device, the problem of the left movable slide rail and the right movable slide rail being difficult to load uniformly during the production process is solved, thereby improving the efficiency of the automated production line, increasing the production speed, and reducing the need for manual intervention. Secondly, through the cooperation of the fixed seat 301 and the movable seat 302, the left movable slide rail and the right movable slide rail are transported alternately in sequence, thereby solving the problem that the operator is easily confused about the left movable slide rail and the right movable slide rail during the loading and unloading process, thereby improving the product qualification rate, improving product quality, and reducing the rework rate.

[0053] Since the outer shape of the movable slide is a hollow rectangular parallelepiped, when the movable seat 302 pushes it to move horizontally, it is easy to cause the left movable slide and the right movable slide on the fixed seat 301 to shift, thereby affecting the processing of the next step. Therefore, in order to ensure the position stability of the movable slide during the movement, the top wall of the fixed seat 301 is provided with a limiting groove 3031 that adapts to the outer wall of the movable slide. The fixed seat 301 is provided with two groups, and the two groups of fixed seats 301 are respectively located at the two ends of the horizontal axis direction of the movable slide. The movable slide is located in the limiting groove 3031 The movable seat 302 is movably assembled with the machine base 1 and is used to vertically lift and longitudinally shift the movable slide rail on the fixed seat 301. Vertical lifting refers to moving up and down along the vertical axis of the machine base 1, and longitudinal shifting refers to moving along the longitudinal axis of the machine base 1. The limit groove 1 3031 opened on the top wall of the fixed seat 301 solves the problem of easy displacement of the movable slide rail during lateral movement, ensures the position stability of the movable slide rail, and improves the conveying accuracy of the movable slide rail. It is worth mentioning that the limit groove 1 3031 and the limit groove 2 3032 are collectively referred to as limit grooves.

[0054] In terms of the specific structure of the movable seat 302 vertically lifting and longitudinally shifting the movable slide rail on the fixed seat 301, the conveying mechanism 3 also includes a lifting cylinder 305, a conveying cylinder 306, and a sliding plate 307. The movable seat 302 is provided with two groups and both are located between the two groups of fixed seats 301. The top wall of the movable seat 302 is provided with a limiting groove 3032 for receiving the movable slide rail. The lifting cylinder 305 is assembled on the sliding plate 307 and is used to push the movable seat 302 to move along the vertical axis direction of the machine base 1. The conveying cylinder 306 is assembled with the machine base 1 and is used to push the sliding plate 307 to move along the longitudinal axis direction of the machine base 1. Through the coordinated work of the lifting cylinder 305 and the conveying cylinder 306, the movable slide rail is lifted and shifted by the movable seat 302, thereby improving the handling efficiency of the left movable slide rail and the right movable slide rail, reducing the labor intensity of manual operation, and improving the degree of automation of the production line. The limiting groove 2 3032 on the top wall of the movable seat 302 solves the positioning problem of the movable slide rail during the lifting and loading process, ensuring that the movable seat 302 can stably receive and transport the movable slide rail.

[0055] In order to reduce the space occupied by the lifting cylinder 305 and the conveying cylinder 306 on the table of the machine base 1, the conveying mechanism 3 also includes a transmission rod 308, a lifting plate 309, and a horizontal plate 310. The lifting cylinder 305, the conveying cylinder 306, and the sliding plate 307 are all located below the machine base 1, and the fixed base 301, the movable base 302, and the horizontal plate 310 are all located above the machine base 1. The fixed end of the conveying cylinder 306 is connected to the machine base 1, and the pushing end of the conveying cylinder 306 is connected to the sliding plate 307. The machine base 1 is provided with a long hole 101, and the transmission rod 308 is slidably assembled with the sliding plate 307. The two ends of the transmission rod 308 are respectively connected to the horizontal plate 310 and the lifting plate 309 and the transmission rod 308 is passed through the long hole 101, the movable base 302 is assembled on the horizontal plate 310, the fixed end of the lifting cylinder 305 is connected to the sliding plate 307, and the movable end of the lifting cylinder 305 is connected to the lifting plate 309. The sliding plate 307 and the machine base 1 are slidably assembled through the slide rail slider. By placing the lifting cylinder 305 and the conveying cylinder 306 under the machine base 1, the problem of the cylinder occupying the table space of the machine base 1 is solved, the layout of the table space of the machine base 1 is optimized, and the utilization rate of the working area is improved. The machine base 1 is provided with a slide groove to solve the guiding problem of the lifting and lateral movement of the transmission rod 308, ensuring the advantage of smooth movement of the transmission rod 308 and improving the movement accuracy of the movable base 302.

[0056] In order to improve the uniformity of the lifting force of the lifting cylinder 305 on the two groups of moving seats 302, in terms of the specific structure of the lifting cylinder 305, four groups of transmission rods 308 are provided, and the four groups of transmission rods 308 are respectively located at the four end corners of the sliding plate 307. The lifting cylinder 305 is located in the middle of the sliding plate 307. There are two groups of cross plates 310, which are used to connect the two groups of transmission rods 308 arranged longitudinally along the machine base 1. The long holes 101 are corresponding to the four groups of transmission rods 308. The moving seat 302 is assembled on the cross plates 310. When the two sets of horizontal plates 310 and the two sets of movable seats 302 are projected onto the table top of the machine base 1, the horizontal plates 310 are arranged perpendicular to the movable seats 302. By arranging four sets of transmission rods 308 at the four end corners of the sliding plate 307 and connecting them with two sets of horizontal plates 310, the jacking force is evenly distributed on the two sets of movable seats 302, which helps to disperse the stress during jacking, increase the stability of the entire structure, and reduce the structural deformation caused by excessive force on a single point, thereby improving the uniformity of the jacking effect and avoiding the problem of tilting of the movable seat 302 due to uneven force.

[0057] In order to optimize the path of the transfer mechanism 8, the transfer mechanism 8 is made to move in a lateral linear motion along the base 1, thereby realizing the staggered loading of the right movable slide rail and the left movable slide rail. The left conveying mechanism 6 and the right conveying mechanism 7 are staggered front and back along the longitudinal axis direction of the base 1, and N groups of limit slots 3031 are provided. The N groups of limit slots 3031 are the first limit slot 3031, the second limit slot 3031, ..., the Nth limit slot 3031 from the side close to the left conveying mechanism 6. The transfer mechanism 8 moves back and forth along the axis of the second limit slot 3031. The first limit slot 3031 is used to place the bearing The left movable slide in the connecting groove and the second limit groove 2 3032 are used to place the right movable slide transported from the right conveying mechanism 7 through the transfer mechanism 8, and then through the lifting, right movement, lowering, and left movement of the movable seat 302, reciprocating operation, thereby moving the left movable slide and the right movable slide on the fixed seat 301 along the axis of the fixed seat 301 in sequence, and placed in the N group of limit grooves 1 3031 in the order of the left movable slide and the right movable slide. As a result, the transfer mechanism 8 clamps the material and moves horizontally in a straight line, which simplifies the structure of the transfer mechanism 8, optimizes the moving path of the transfer mechanism 8, and improves the loading efficiency of the movable slide.

[0058] It is worth mentioning that multiple groups of limit grooves 1 3031 are arranged at equal intervals on the fixed base 301, and multiple groups of limit grooves 2 3032 are arranged at equal intervals on the movable base 302. The spacing between two adjacent groups of limit grooves 1 3031 is equal to the spacing between two adjacent groups of limit grooves 2 3032, and is equal to the distance that the movable base 302 moves horizontally along the base 1.

[0059] In the specific structure of the transfer mechanism 8, the transfer mechanism 8 includes a support 801, a lateral transfer block 802, a vertical transfer block 803, a second clamping jaw 804, a second clamping jaw cylinder 805, a lateral screw 806, a lateral nut 807, a lateral motor, and a vertical push cylinder 808. The support 801 is assembled on the machine base 1 and is located above the fixed base 301. The lateral transfer block 802 is slidably assembled on the side wall of the support 801 along the horizontal axis direction of the support 801. The lateral movement motor is connected to the support 801 and is used to rotate the lateral movement nut 807. The lateral movement nut 807 is threadedly connected to the lateral movement screw 806. The lateral movement block 802 is connected to the lateral movement nut 807. The lateral movement block 802 and the support 801 are slidably connected through the slide rail slider. The vertical movement block 803 is slidably assembled on the side wall of the lateral movement block 802 along the vertical axis direction of the lateral movement block 802. The fixed end of the vertical push motor is connected to the lateral movement block 802. The movable end of the vertical push motor is connected to the horizontal moving block 802, and the vertical moving block 803 is connected to the horizontal moving block 802 through the slide rail slider. The second clamping claw cylinder 805 is connected to the vertical moving block 803 and is used to drive the second clamping claw 804 to clamp the two opposite side walls of the right moving slide rail. The clamping end of the second clamping cylinder has two groups of clamping claws. The second clamping claw cylinder 805 is provided with two groups and is spaced apart along the horizontal direction of the moving block. The second clamping cylinder 805 is pushed downward by the vertical pushing cylinder 808, and the second clamping claw 804 is driven to clamp the two ends of the right movable slide rail through two groups of second clamping claw cylinders 805 set at intervals. Then the vertical pushing cylinder 808 drives the second clamping claw cylinder 805 to move upward, and the transverse motor rotates to drive the transverse moving base to move, and then the vertical pushing cylinder 808 is driven to place the right movable slide rail in the second limit groove 3031, thereby realizing the transportation of the right movable slide rail.

[0060] In order to improve the clamping efficiency of the transfer mechanism 8 on the right moving slide rail and to block the right moving slide rail on the conveying mechanism, in terms of the specific structure of the right conveying mechanism 7, the right conveying mechanism 7 includes a right conveyor belt 701, a guide block 702, a lifting cylinder 703, and a lifting block 704. The right conveyor belt 701 is assembled above the machine base 1, and the guide block 702 is provided with two groups and is respectively located at the two ends of the transverse axis direction of the right conveyor belt 701. The lifting cylinder 703 is assembled with the machine base 1 and is located below the second clamping claw cylinder 805. The lifting block 704 is connected to the pushing end of the lifting cylinder 703 and is used to lift the right moving slide rail on the guide block 702 toward the second clamping claw cylinder 805. The blocking block 410 is set in an L shape, which is used to limit the right moving slide rail from sliding off the right conveyor belt 701 and moving the right The slide rail is placed on the right conveyor belt 701. Driven by the right conveyor belt 701, the right movable slide rail is moved onto the guide block 702, and is lifted by the lifting cylinder 703 to push the right movable slide rail toward the second clamping jaw 804. At this time, the vertical push cylinder 808 pushes the second clamping jaw 804 to move in the direction of the lifting block 704, and moves in both directions, thereby improving the clamping efficiency. Secondly, since the right movable slide rail is lifted by the lifting block 704, it is convenient for the second clamping jaw 804 to clamp the right movable slide rail. The lifting block 704 limits the right movable slide rail on the guide block 702 while lifting. It is worth mentioning that in order to improve the lifting stability of the lifting block 704 on the right movable slide rail, the lifting block 704 is arranged in two groups along the horizontal axis direction of the right movable slide rail and is staggered with the two groups of second clamping jaws 804.

[0061] In order to improve the conveying mechanism 3's ability to transport movable slide rails of different lengths and improve the compatibility of the alternating loading device, the conveying mechanism 3 also includes a horizontal adjustment screw 311, a horizontal adjustment nut 312, and an adjustment handle 313. The horizontal adjustment nut 312 is connected to the machine base 1, and the horizontal adjustment screw 311 is threadedly connected to the horizontal adjustment nut 312, and the axis of the horizontal adjustment screw 311 is arranged parallel to the horizontal axis of the machine base 1. The fixed seat 301 and the machine base 1 are slidably assembled through a slide rail slider. One end of the horizontal adjustment screw 311 is connected to the side wall of the fixed seat 301, and the other end of the horizontal adjustment screw is axially connected to the adjustment handle 313. By rotating the adjustment handle 313, the horizontal distance between the two groups of fixed seats 301 can be adjusted, thereby being compatible with movable slide rails of different lengths and improving the compatibility with the conveying mechanism 3.

[0062] Furthermore, in order to match slide rails of different lengths, the transfer mechanism 8 also includes an adjustment plate, and the vertical transfer block 803 is provided with a sliding groove. One end of the adjustment plate is slidingly fixedly connected to the sliding groove, and the other end of the adjustment plate is connected to the fixed end of the second clamping cylinder 805. In terms of the adjustment of the left conveying mechanism 6 and the right conveying mechanism 7, the left conveying mechanism 6 also includes an adjustment plate and a guide rod. The guide rod is parallel to the left movable slide rail on the conveyor belt, and the adjustment plate and the guide rod are slidingly fixedly assembled to limit the two ends of the left movable slide rail. In terms of the specific structure of the left conveying mechanism 6, the left conveying mechanism 6 includes a left conveyor belt 601. The adjustment method of the left conveying mechanism 6 is the same as that of the left conveying mechanism 6, which will not be repeated here.

[0063] Example 3: Figure 1-10 As shown, a left and right rail pick welding device includes a left and right rail alternating feeding device in Example 2, and also includes a pick welding device for a drawer slide in Example 1. The machine base 1 is also equipped with a blanking mechanism 9 for blanking the movable slide. The pick welding device is provided in two groups symmetrically along the transverse direction of the fixed seat 301. The pick welding device close to the right conveying mechanism 7 is used for welding the left movable slide, and the pick welding device away from the right conveying mechanism 7 is used for welding the right movable slide. The blanking mechanism 9 is located at the end of the fixed seat 301 away from the right conveying mechanism 7. The unloading mechanism 9 includes a unloading plate 901, a unloading cylinder 902, and an unloading conveyor belt 903. The unloading plate 901 is provided with two groups and is respectively connected to two groups of fixed seats 301. The unloading plate 901 is provided with two groups of unloading troughs 9011 along its vertical axis direction. The unloading cylinder 902 is connected to the unloading plate 901 for limiting the movable slide rail on the unloading trough 9011. The unloading conveyor belt 903 is located directly below the unloading plate 901. The unloading conveyor belt 903 has a raised dividing strip 9031, and the dividing strip 9031 is located between the two groups of unloading troughs 9011.

[0064] During operation, the left moving slide rail and the right moving slide rail are transported by the conveying mechanism 3, and the pushing mechanism 5 pushes the left moving slide rail and the right moving slide rail to the corresponding welding mechanism 2 for welding. The welded slide rails are transported by the moving seat 302, and the left moving slide rail and the right moving slide rail are placed on the two groups of unloading troughs 9011 on the unloading plate 901 respectively. Then the push rod of the unloading cylinder 902 is transformed from the extended state to the retracted state, and the left moving slide rail and the right moving slide rail slide from the two groups of unloading troughs 9011 to the unloading conveyor belt 903 at the same time. Under the separation effect of the dividing bar 9031, the left moving slide rail and the right moving slide rail are transported separately, which is convenient for distinguishing and collecting materials.

[0065] The advantages of saddle-type drawer slides lie in their excellent load-bearing capacity, outstanding stability, and durability. Through their unique suspension structure, they can effectively disperse the weight of the drawer, reducing the burden on a single slide, thereby achieving smoother drawer movement. In addition, the symmetrical design and even distribution of weight of the saddle-type slides enable them to maintain excellent performance even under frequent use. Saddle-type drawer slides are becoming increasingly popular in modern furniture design. The welding equipment in this embodiment is suitable for the welding production of the paddles and movable slides of saddle-type drawers.
