A plurality of carrier trolleys 3 are slidably arranged on the trolley track 2, and the carrier trolleys 3 are placed on the trolley track 2 and can slide along the direction of the trolley track 2. An intermittent drive mechanism 4 for driving the carrier trolleys 3 to move is provided at the upper end of the conveyor frame 1, and the intermittent drive mechanism 4 is located behind the trolley track 2.

In application, the carrier trolley 3 is placed on the trolley track 2 and then moved by the intermittent drive mechanism 4 to achieve intermittent movement, thereby completing the movement of the carrier trolley 3 to each workstation. When the carrier trolley 3 completes all assembly or inspection work, the carrier trolley 3 will enter the trolley unloading mechanism 7, and then an external robot or worker will remove the product. The empty carrier trolley 3 is moved by the trolley unloading mechanism 7 to the lower end of the conveyor frame 1 and sent to the return conveyor mechanism 5. Subsequently, the return conveyor mechanism 5 moves the empty carrier trolley 3 to the trolley loading mechanism 6, and then the trolley loading mechanism 6 moves to the upper end of the conveyor frame 1 and sends it to the inlet end of the trolley track 2, so that an external robot or worker can place a new product, thereby realizing the cyclical use of the carrier trolley 3.

[0031] like Figure 3 As shown, in this embodiment, the intermittent drive mechanism 4 includes a sliding long plate 401 that is laterally slidably disposed on the conveyor frame 1. The sliding long plate 401 is slidably disposed on the sliding base plate 407 via a horizontal slide rail and multiple horizontal sliders. The sliding base plate 407 is fixed on the conveyor frame 1. Therefore, the sliding long plate 401 can slide left and right relative to the sliding base plate 407. Furthermore, the sliding long plate 401 is parallel to the trolley track 2, and therefore also moves left and right relative to the trolley track 2, that is, it moves back and forth along the setting direction of the trolley track 2.

[0032] The two sides of the sliding bottom plate 407 are provided with limiting seats 408, and buffers and limiting columns matched with the sliding long plate 401 are fixedly arranged on the limiting seats 408, the buffers are used for buffering the terminal movement of the sliding long plate 401, so that the sliding long plate 401 is prevented from moving too fast at the terminal stroke, and the limiting columns are used for limiting the sliding long plate 401, so that the moving stroke of the sliding long plate 401 is within a set range;

[0033] The rear side of the sliding long plate 401 is provided with a conveying cylinder 402, the conveying cylinder 402 is fixed on the sliding bottom plate 407, and the conveying cylinder 402 is used for driving the sliding long plate 401 to move left and right; a plurality of trolley clamping plates 403 are arranged on the sliding long plate 401, and equal intervals are arranged between every two trolley clamping plates 403, and each trolley clamping plate 403 corresponds to an assembly station / detection station; all the trolley clamping plates 403 are longitudinally slid on the sliding long plate 401 through sliding blocks and sliding rails, that is, can slide forward and backward, so as to be close to or away from the trolley track 2 and cooperate with the carrier trolley 3, all the trolley clamping plates 403 are connected through a linkage long plate 404, so that all the trolley clamping plates 403 are synchronous actions; a clamping groove 405 is formed in the trolley clamping plate 403 and matched with the carrier trolley 3, the carrier trolley 3 can be clamped in the clamping groove 405, so as to drive the carrier trolley 3 to move; a clamping cylinder 406 connected with the linkage long plate 404 is arranged on the sliding long plate 401, the clamping cylinder 406 is used for driving all the trolley clamping plates 403 to move forward and backward, so as to realize cooperation with or disengagement from the carrier trolley 3;

[0034] In actual application, the carrier trolley 3 is placed on the trolley track 2 and initially located at the front side of the trolley clamping plate 403 at the leftmost end to perform assembly / detection at the first station. Then the clamping cylinder 406 is driven to move the trolley clamping plate 403 forward to be clamped on the carrier trolley 3. Then the conveying cylinder 402 is reset to drive the sliding long plate 401 to move rightward, so that the trolley clamping plate 403 moves rightward and drives the carrier trolley 3 to move forward along the trolley track 2 to the second station. Then the clamping cylinder 406 is reset to contact the trolley clamping plate 403 and the carrier trolley 3. The conveying cylinder 402 is driven to move the sliding long plate 401 leftward to the original position. At the same time, the second carrier trolley 3 is placed on the trolley track 2 and located at the front side of the trolley clamping plate 403 at the leftmost end, i.e. the first station. At this time, the two carrier trolleys 3 at the second station and the first station have completed the assembly / detection work. The clamping cylinder 406 is started again to make the two carrier trolleys 3 clamped by the corresponding trolley clamping plates 403 and move forward under the action of the conveying cylinder 402 to realize station switching. The subsequent work process is the same as above.

[0035] As shown in Figures 4 to 8 In this embodiment, the carrier trolley 3 comprises a trolley body 301, and a product carrier 302 is arranged on the trolley body 301, which is used for loading and fixing products. The trolley body 301 has a stepped structure, and two conveying bearings 303 and two limiting bearings 304 are arranged on both sides of the trolley body 301. The two conveying bearings 303 and the two limiting bearings 304 are distributed at both ends of the trolley body 301 to ensure force balance.

[0036] The conveying bearing 303 is vertically arranged and is used for being clamped on the trolley track 2 to slide along the trolley track 2 to realize movement. The limiting bearing 304 is horizontally arranged and located below the inner side of the conveying bearing 303. Therefore, when the trolley body 301 is clamped on the trolley track 2, the limiting bearings 304 on both sides will contact the inner side of the trolley track 2 to play a limiting role and prevent overturning.

[0037] The middle part of the two sides of the trolley body 301 is provided with a card slot matched with the trolley card plate 403, a matching bearing 305 is horizontally arranged in the card slot, the matching bearing 305 is matched with the card slot 405, that is, the trolley card plate 403 is actually clamped in the card slot when it is embedded in the carrier trolley 3, and the card slot 405 can contain the matching bearing 305, so that the matching with the carrier trolley 3 can be realized to drive the carrier trolley 3 to move, and because the bearing structure is adopted, the friction can be reduced when driving the carrier trolley 3, and the wear of the trolley card plate 403 can be reduced;

[0038] The trolley track 2 comprises two symmetrical track side plates 201, the conveying bearings 303 of the carrier trolley 3 are respectively arranged on the two track side plates 201, and the limiting bearings 304 are matched with the limiting transverse grooves 202 arranged on the inner sides of the track side plates 201, so that in actual use, the carrier trolley 3 moves along the trolley track 2, the limiting bearings 304 are limited in and move along the limiting transverse grooves 202, so that the carrier trolley 3 will not overturn during movement, and the stability of conveying is ensured.

[0039] In the embodiment, a plurality of conveying positioning members 203 are arranged on the inner sides of the two track side plates 201, and the conveying positioning members 203 of the two fixed side plates are symmetrical, so as to ensure the positioning of the carrier trolley 3, and each conveying positioning member 203 is located at a station, that is, the position of the trolley card plate 403, so as to ensure that the carrier trolley 3 can be accurately parked at the set position.

[0040] The conveying positioning member 203 comprises a positioning mounting block 231, a positioning pressing strip 232, a positioning bearing 233 and a first spring 234, a long slot is arranged in the middle part of the positioning mounting block 231, a cylindrical pin is arranged in the middle part of the long slot, the middle part of the positioning pressing strip 232 is hinged to the long slot through the cylindrical pin, the positioning bearing 233 is horizontally arranged at the upper end of the positioning pressing strip 232, and the first spring 234 is located between the lower end of the positioning pressing strip 232 and the long slot, so as to provide floating force for the positioning pressing strip 232, so that the positioning pressing strip 232 can be inwardly turned to a certain extent and can be automatically reset.

[0041] The middle part of the two sides of the trolley body 301 is provided with a positioning clamping block 306, which is located on the inner side of the matching bearing 305, and the inner side of the positioning clamping block 306 is provided with an arc-shaped positioning groove 307 matched with the positioning bearing 233. Through the cooperation between the positioning clamping block 306 and the positioning bearing 233, the carrier trolley 3 can be positioned, and the arc-shaped positioning groove 307 can ensure the positioning effect of the positioning bearing 233. Since the positioning bearing 233 can rotate, the friction between the positioning clamping block 306 and the positioning bearing 233 can be reduced during positioning, ensuring smooth movement and improving the overall service life.

[0042] In actual application, the carrier trolley 3 moves along the trolley track 2. When the carrier trolley 3 is positioned, the positioning clamping block 306 first contacts the positioning bearing 233, and the positioning bearing 233 is forced to flip inward and rotate against the positioning clamping block 306. After the carrier trolley 3 is positioned, the positioning bearing 233 falls into the arc-shaped positioning groove 307 and presses the positioning clamping block 306 under the action of the first spring 234, thereby playing a positioning role. The overall outer periphery of the positioning clamping block 306 is designed as a circular arc surface, thereby avoiding the positioning bearing 233 from being stuck, thereby ensuring smooth movement. In order to make the carrier trolley 3 run more smoothly, the conveying bearing 303 is fixed on the mounting block, and the mounting block is installed in the structure of equal height screw + spring to obtain the floating effect, thereby making the carrier trolley 3 have a damping effect.
