Description

Technical Field

[0001] This utility model relates to the field of automated production equipment technology, specifically to an alternating feeding mechanism. Background Technology

[0002] In the automated processing and production of products, large-scale factories use automated production lines to carry out operations. The product processing process usually includes steps such as loading, processing, assembly, and unloading of different workpieces. In the product loading process, the product is taken out from the previous process or tray and transferred to the processing station. In this process, the position of picking up the material and the position of conveying it to the processing station are fixed and accurate, so as to achieve the purpose of accurate picking and convenient processing.

[0003] Currently, the loading process is usually achieved using linear modules or robotic arms, with two fixtures located at the loading station and the processing station respectively. The product from the previous process or the material tray needs to be placed on the fixture at the loading station beforehand. After the loading mechanism picks up the product, it is transferred to the fixture at the processing station to complete the loading work. At the same time, in order to improve efficiency, a dual-station loading mechanism is usually set up, which can realize the alternation of loading and transfer, thereby improving loading efficiency.

[0004] However, regardless of whether a linear module or a robotic arm is used to complete the loading, the structure is relatively complex and the production cost is high.

[0005] Therefore, there is an urgent need for a technology to solve the above-mentioned technical problems. Utility Model Content

[0006] One objective of this utility model is to provide an alternating feeding mechanism to solve the aforementioned technical problems. The utility model adopts the following technical solution: An alternating feeding mechanism includes: The feeding track includes two slide rails arranged side by side with a gap between them, and a meeting channel is defined between the two slide rails; The base includes two movably mounted on the slide rails, with the starting positions of the two bases located at the ends of the two slide rails that are far apart from each other. A fixture seat for loading a workpiece is disposed on the base, and the axes of the two fixture seats are on the same straight line and located within the meeting channel. A driving device is simultaneously connected to both of the seats, driving the two seats to reciprocate in opposite directions; An obstacle avoidance structure is provided between the corresponding seats and the feeding track, which causes the two seats to stagger and avoid each other when they meet in the meeting channel.

[0007] Furthermore, the seat includes a base fixedly mounted on the slide rail and a mounting plate slidably connected to the base along the direction toward the centerline of the meeting channel, and the fixture seat is fixedly mounted on the mounting plate.

[0008] Furthermore, the avoidance structure includes: An elastic element is provided between the base plate and the mounting plate, so that the mounting plate can slide elastically toward the centerline of the meeting channel under the elastic force of the elastic element. A guide rod is formed at one end of the mounting plate away from the meeting channel, and the guide rod extends downward in a vertical direction; A cam surface, which is formed on the sidewall outside the feeding track, includes a protrusion extending outward.

[0009] Furthermore, a rotatable wheel is provided at the end of the guide rod, and the wheel abuts against the cam surface.

[0010] Furthermore, the protrusion is formed at the middle position along the length direction of the feeding track.

[0011] Furthermore, it also includes a base plate, on which a through groove is formed along a predetermined direction, the through groove defining the meeting channel, and two slide rails are correspondingly fixedly mounted on both sides of the through groove.

[0012] Furthermore, the driving device includes: The synchronous pulley includes two rotatably disposed at both ends of the feeding track, and a synchronous belt is sleeved between the two synchronous pulleys, and the two seat bodies are respectively fixedly connected to the belt bodies located on both sides of the synchronous belt; A drive cylinder is fixedly mounted on the feeding rail and is connected to any one of the seats to drive it to reciprocate along the slide rail direction and drive the other seat to move in opposite directions.

[0013] Furthermore, the feeding track is also equipped with limit blocks located at both ends in the length direction, and each of the limit blocks is provided with a contact switch corresponding to the two seats respectively.

[0014] The beneficial effects of this utility model are as follows: This utility model provides an alternating feeding mechanism. Two seats are slidably connected to two parallel slide rails and are driven by a drive device to alternately reciprocate between the feeding station and the processing station for feeding. During the reciprocating movement, the two seats can stagger each other when they meet through a clearance structure, ensuring smooth passage and thus successfully completing the feeding operation. As can be seen from the above, the alternating feeding mechanism provided in this embodiment has a simple and reliable structure. It can simultaneously drive the two seats synchronously under the drive of the drive device. Furthermore, by setting the axes of the two fixture seats on the same straight line, it can ensure the relative accuracy of the feeding position and the processing position, avoiding inaccurate feeding or processing after position changes. The clearance structure allows the two seats to stagger each other when they meet, ensuring smooth passage. The feeding mechanism provided by this technical solution can conveniently and quickly complete the feeding operation, and its simple and reliable structure also results in low cost during equipment processing and assembly.

Detailed Implementation

[0019] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention. The present invention will be described in detail below with reference to the accompanying drawings.

[0020] In this embodiment of the utility model, an alternating feeding mechanism is provided to automate the product feeding operation in production equipment, such as... Figure 1-3As shown, this embodiment provides an alternating feeding mechanism, including a feeding track 100, a seat 200 movably disposed on the feeding track 100, and a driving device 300 for reciprocating movement of the seat 200. Specifically, the feeding track 100 includes two slide rails 101 arranged side by side at intervals, and a meeting channel 102 is defined between the two slide rails 101; the seat 200 includes two seats movably disposed on the slide rails 101, and the starting positions of the two seats 200 are respectively located at the ends of the two slide rails 101 that are far apart from each other. A fixture seat 210 for loading workpieces is disposed on the seat 200, and the axes of the two fixture seats 210 are located on the same straight line and within the meeting channel 102; the driving device 300 is simultaneously connected to the two seats 200 for transmission, driving the two seats 200 to reciprocate in opposite directions.

[0021] The two fixture seats 200 are synchronously driven by the drive device 300, enabling them to reciprocate between the loading station and the processing station, thus achieving alternating loading operations and improving loading efficiency. Furthermore, by aligning the axes of the two fixture seats 210 on the same straight line and within one of the meeting channels 102, the relative positions of the fixture seats 210 at the loading and processing stations are determined, ensuring positional certainty during loading or processing. Simultaneously, a clearance structure is provided between the fixture seats 200 and the loading track 100. When the two fixture seats 200 meet in the meeting channel 102, they are staggered to avoid each other, ensuring misalignment during reciprocating movement and preventing mutual interference.

[0022] During the operation of this alternating feeding mechanism, the two seats 200, driven by the drive device 300, reciprocate along the slide rail 101 between the feeding station and the processing station to feed the product toward the processing station, thereby performing processing operations on the workpiece. In this embodiment, the processing station can complete processing such as workpiece inspection, painting, machining, and coding identification. By setting the two seats 200 at both ends of the feeding track 100 in the initial state, the two seats 200 can respectively interact with the feeding station and the processing station. The processing stations correspond to each other, thus enabling an alternating feeding method to improve feeding efficiency. Under the drive of the drive device 300, the two seats 200 move synchronously towards each other to complete the feeding operation. Furthermore, a clearance structure is provided between the seats 200 and the feeding track 100, which can stagger the two seats 200 to avoid each other when they meet in the meeting channel 102, allowing the two seats 200 to pass smoothly without interfering with each other and affecting normal passage.

[0023] In this technical solution, two seats 200 are slidably connected to two parallel slide rails 101, and are simultaneously driven by a drive device 300 to alternately reciprocate between the loading station and the processing station for loading. During the reciprocating movement, the two seats 200, through a clearance structure, can stagger each other when they meet, ensuring smooth passage and thus successfully completing the loading work. As can be seen from the above, the alternating loading mechanism provided in this embodiment has a simple and reliable structure, and can simultaneously complete the loading of two... The two fixture seats 210 are driven synchronously, and their axes are aligned on the same straight line. This ensures the relative accuracy of the loading and processing positions, preventing inaccurate loading or processing due to position changes. The avoidance structure allows the two fixture seats 200 to pass smoothly when they meet, ensuring smooth passage. The loading mechanism provided by this technical solution can complete the loading operation conveniently and quickly, and its simple and reliable structure results in lower costs during equipment processing and assembly.

[0024] In this embodiment, the seat 200 includes two parts. Specifically, the seat 200 includes a base 201 fixedly mounted on the slide rail 101 and a mounting plate 202 slidably connected to the base 201 along the direction toward the centerline of the meeting channel 102. The fixture seat 210 is fixedly mounted on the mounting plate 202.

[0025] Meanwhile, the avoidance structure allows the two seats 200 to stagger each other when they meet during movement, thus avoiding each other and ensuring smooth passage. For example, Figure 2-3 As shown, the avoidance structure includes an elastic element 221, a guide rod 222, and a cam surface formed on the feeding track 100. Specifically, it is elastically disposed between the base plate and the mounting plate 202, so that the mounting plate 202 slides elastically toward the centerline of the meeting channel 102 under the elastic force of the elastic element 221; the guide rod 222 is formed at one end of the mounting plate 202 away from the meeting channel 102, and the guide rod 222 extends downward in the vertical direction; the cam surface is formed on the side wall of the outer side of the feeding track 100, and includes a protrusion 223 protruding outward in the direction of the outer side.

[0026] When the two seats 200 are driven by the drive device 300 to reciprocate, at the initial position, the mounting plate 202 extends towards the meeting channel 102 under the elastic tension of the elastic member 221, so that the axes of the two jig seats 210 are kept on the same straight line and located at one of the positions within the range of the meeting channel 102. In this embodiment, in order to reduce the processing cost of the feeding mechanism, the two seats 200 are identical in structure, and the avoidance structure is also composed of identical parts. The axes of the two jig seats 210 are located at the center line of the meeting channel 102. Because the positions of the two seats 200 remain unchanged at the initial position, the product can be accurately fed and processed. It is known that when the mounting plate 202 is in the middle position, the axes of the two jig seats 210 are kept on the same straight line and located at one of the positions within the range of the meeting channel 102. A limiting structure is provided between the mounting plate 202 and the base plate to prevent the mounting plate 202 from extending too far into the meeting channel 102 under the pull of the elastic element 221. The limiting structure can be implemented by any existing technical solution, and no specific limitation is made here. When the driving device 300 drives the two seats 200 to move synchronously towards each other, as the two seats 200 gradually approach each other, the guide rod 222 gradually pulls the mounting plate 202 away from the meeting channel 102 under the guidance of the cam surface. When it moves to the position of the protrusion 223, the mounting plate 202 is farthest from the meeting channel 102, so that the two mounting plates 202 move away from each other and intersect each other, thus avoiding mutual interference during the movement. It is worth noting that during the setting of the cam surface, when the guide rod 222 has not moved to the protrusion 223, the distance by which the two mounting plates 202 are simultaneously pulled away from the meeting channel 102 allows the two mounting plates 202 to intersect each other. At the position of the protrusion 223, the distance between the two mounting plates 202 is the largest, thereby further avoiding mutual interference. It is understood that in this embodiment, the base 201 can be set as a slider that is slidably connected to the slide rail 101. Therefore, the two bases 201 will not interfere with each other during the movement. The components that interfere with each other are the mounting plates 202. Therefore, after pulling the two mounting plates 202 away from the meeting channel 102, the purpose of mutual intersecting avoidance of the seats 200 can be achieved.

[0027] In this embodiment, to ensure smoother movement between the guide rod 222 and the cam surface, a rotatable wheel 2221 is provided at the end of the guide rod 222, and the wheel 2221 abuts against the cam surface. In this embodiment, the wheel 2221 can be implemented using a bearing, thereby enabling the guide rod 222 to move the mounting plate 202 under the guidance of the cam surface.

[0028] In this embodiment, the two seats 200 move synchronously and toward each other under the drive of the drive device 300 and meet at the middle position of the feeding track 100. In order to enable the two seats 200 to avoid each other and prevent interference, the protrusion 223 is formed at the middle position of the feeding track 100 along the length direction.

[0029] In this embodiment, the feeding track 100 also includes a base plate 103. The base plate 103 has a through groove 1031 along a predetermined direction. The through groove 1031 is defined as a meeting channel 102. Two slide rails 101 are fixedly mounted on both sides of the through groove 1031.

[0030] In this embodiment, as Figure 1-3 As shown, the drive device 300 includes a synchronous pulley 301, a synchronous belt 302, and a drive cylinder 303. Specifically, the synchronous pulley 301 includes two rotatably disposed at both ends of the feeding track 100, and the synchronous belt 302 is sleeved between the two synchronous pulleys 301. The two seats 200 are respectively fixedly connected to the belt body located on both sides of the synchronous belt 302. The drive cylinder 303 is fixedly mounted on the feeding track 100 and is connected to any one of the seats 200 for transmission, so as to drive it to reciprocate along the slide rail 101 and drive the other seat 200 to move in the opposite direction.

[0031] Two seats 200 are fixedly connected to the belt body of the timing belt 302 on both sides by connecting plates. In this embodiment, the connecting plates extend downward along the through groove 1031 and are fixedly connected to the belt body. At the same time, the drive cylinder 303 is fixedly connected to the connecting plate of one of the seats 200. Thus, when the cylinder 303 drives one seat 200 to move, the timing belt 302 can drive the other seat 200 to move relative to it. The drive device 300 of this feeding mechanism is realized by only the cylinder 303, the timing pulley 301 and the timing belt 302. Its driving method is simple and the stroke is fixed, which can realize accurate feeding operation and has low production cost.

[0032] In this embodiment, to further improve the accuracy of the seat 200 during movement, limit blocks 104 located at both ends in the length direction are also configured on the loading track 100, and each limit block 104 is provided with a contact switch 1041 corresponding to the two seats 200 respectively. When the limit block 104 moves to the limit position, it contacts the contact switch 1041, thereby stopping the cylinder 303 and preventing the seat 200 from having an excessively large travel distance, which would affect the accuracy at the processing station or loading station.

[0033] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the present utility model without departing from the scope of the present utility model shall fall within the scope of the present utility model.
