Specific embodiments

[0026] The present utility model will be further described below through specific embodiments.

[0027] Referring to Figures 1 to 8 shown, a handling robot adaptable to turnover boxes of different sizes includes a frame 1, a docking station 2 provided at the top of the frame 1, a roller conveyor assembly 3 provided in the docking station 2, and a blocking mechanism 4 movably provided on the docking station 2.

[0028] Frame 1 includes a moving base 5 and a connecting mechanism 6 detachably connected between the moving base 5 and the transfer table 2. The connecting mechanism 6 includes a support base 61 provided on the top of the moving base 5, two connecting brackets 62 oppositely arranged on the support base 61 and connected to the transfer table 2, and a plurality of connecting columns 63 provided between the support base 61 and the top of the moving base 5. Among them, there are four connecting columns 63, which are arranged in a matrix between the support base 61 and the top of the moving base 5, and the connecting columns 63 are respectively connected to the support base 61 and the top of the moving base 5 through connecting bolts 64. By defining the structure of the frame 1 and setting the connecting mechanism 6, the detachable connection between the moving base 5 and the transfer table 2 is realized, so that the moving base 5 and the transfer table 2 can be used as independent components. When a certain component is damaged, only the corresponding part needs to be removed for replacement and repair, without the need to disassemble the whole machine as before to repair the corresponding damaged component. Moreover, the setting of the connecting mechanism 6 enables the undamaged components to be recombined with the corresponding components of the handling robot of the same model without waiting for the damaged components to be repaired before working, effectively improving the transportation efficiency of goods.

[0029] The support base 61 includes a support base body 611 with openings 613 formed on both sides and two sealing plates 612 respectively provided on both sides of the support base body 611 for sealing the openings 613. The two connecting columns 63 on the same side are opposite to the openings 613 on the opposite side, and the sealing plates 612 are fixed between the two connecting columns 63 on the same side through locking bolts 65. Correspondingly, a support step 51 extending downward for supporting the support base 61 is formed on the top of the moving base 5, a first positioning edge 614 that can be supported on the support step 51 is formed at the lower end of the support base body 611, and a second positioning edge 615 that can be supported on the support step 51 is formed at the lower end of the sealing plate 612. Through the cooperation of the first positioning edge 614, the second positioning edge 615 and the support step 51, the rough positioning of the support base 61 and the moving base 5 can be quickly realized, facilitating the subsequent tightening of the bolts.

[0030] The connecting bracket 62 includes a connecting frame 621 extending upward on the support base 61, a connecting plate 62 connected to the transfer table 2 at the upper end of the connecting frame 621, and a connecting housing 623 sleeved on the outer periphery of the connecting frame 621. Moreover, weight-reducing holes 624 are provided on both the connecting frame 621 and the connecting plate 622 to reduce the overall weight of the equipment.

[0031] The transfer table 2 includes a placement cavity 21 extending inward from its front end for placing turnover boxes and a stop bar 22 rotatably provided at the rear end of the transfer table and capable of pressing down the turnover boxes. Among them, the front end of the placement cavity 21 is lower than the rear end, so that the placement cavity 21 forms a semi-enclosed structure to prevent the turnover boxes entering the placement cavity 21 from detaching backward from the placement cavity 21. Specifically, a limiting portion 23 for restricting the rotation angle of the stop bar 22 is formed on the opposite surface of the rear end of the transfer table 2 where the stop bar 22 rotates.

[0032] The blocking mechanism 4 includes a blocking member 41 that can move back and forth relative to the front end of the roller track transmission assembly 3, and a moving member 42 that is arranged on the connection table 2 and connected to and drives the blocking member 41 to move back and forth. The moving member 42 drives the blocking member 41 to move back and forth to limit the positions of turnover boxes of different sizes in the placement cavity 21, ensuring the stability of turnover boxes of different sizes during transportation.

[0033] The blocking member 41 includes a blocking seat 411 connected to the moving member 42, a first blocking rod 412 and a second blocking rod 413 rotatably arranged on the blocking seat 411, a blocking motor 414 arranged on the blocking seat 411 and connected to and driving the first blocking rod 412 to rotate, a synchronizing rod 415 connected between the first shifting rod 412 and the second blocking rod 413, a connecting shaft 416 arranged on the blocking seat 411 and connected to the second blocking rod 413, and a proximity sensor 417 arranged on the blocking seat 411 for detecting whether the turnover box enters the connection table 2. When the proximity sensor 417 senses that the turnover box enters the placement cavity 21, the blocking motor 414 controls the first blocking rod 412 to rotate and drives the second blocking rod 412 to rotate upward synchronously until the upper end thereof is located above the roller track transmission assembly 3 to limit the outward movement of the turnover box.

[0034] The moving member 42 includes a moving motor 421 arranged on the connection table 2, a lead screw nut pair 422 arranged between the moving motor 421 and the blocking seat 411, two guiding slide rails 423 oppositely arranged on both sides of the lead screw nut pair 422, and guiding sliders 424 oppositely arranged at the bottom of the blocking seat 411 and respectively cooperating with the two guiding slide rails 423.

[0035] In this application, by defining the structure of the blocking mechanism 4, the moving member 42 cooperates with the blocking member 41 to enable the blocking member 41 to limit turnover boxes of different sizes at different positions, ensuring the stability of turnover boxes of different sizes during transportation; and the setting of the blocking member 41 can cooperate with the semi-enclosed placement cavity 21 and the retaining rod 22, so that the turnover box in the placement cavity 21 can be stably placed in the placement cavity 21, preventing the turnover box from being opened or lost during transportation, and also avoiding the turnover box from rushing out due to inertia when braking suddenly in an emergency during transportation.

[0036] The above is only a preferred embodiment of the present utility model, and thus cannot limit the scope of implementation of the present utility model. That is, equivalent changes and modifications made according to the scope of the patent application of the present utility model and the content of the specification should still fall within the scope covered by the patent of the present utility model.
