Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the present invention.

[0025] Embodiment 1:

[0026] A tray positioning assembly in a preferred embodiment of the utility model, such as Figure 1 As shown, it includes at least two groups of positioning and clamping units 10 arranged opposite to each other; a channel 101 for the tray to pass through is provided between the two positioning and clamping units 10; the two positioning and clamping units 10 simultaneously and synchronously position and clamp the tray; and the clamping is more stable.

[0027] like Figure 2 As shown, the positioning and clamping unit 10 includes a base 11, on which a rotating shaft 12 is rotatably provided, and on which a first positioning fork 13 for positioning the pallet is fixedly provided; the first positioning fork 13 includes a first pin 131, a second pin 132 overlapping the first pin 131, and a connecting shaft 133 fixedly sleeved on the rotating shaft 12 and connecting the first pin 131 and the second pin 132; the first pin 131 is parallel to the second pin 132, and a clamping space 01 is formed between the first pin 131 and the second pin 132; a rotating driving component 14 is also provided on the base 11; a transmission component 15 is provided between the first pin 131 and the second pin 132, which has a compact structure and further reduces the volume; the rotating driving component 14 drives the first positioning fork 13 to rotate toward the pallet or away from the pallet through the transmission component 15; in this embodiment, the positioning grooves for plugging and positioning with the first pin are provided at the front and rear ends of the pallet, which is convenient for clamping;

[0028] Optionally, a longitudinal storage position A and a transverse material fixing position B are provided on the base along the moving trajectory of the first positioning fork 13; the rotary drive assembly cooperates with the transmission assembly to drive the first positioning fork and the rotating shaft to rotate back and forth between the longitudinal storage position A and the transverse material fixing position B; further, a first sensor is provided on the base to detect whether there is a first positioning fork 13 at the longitudinal storage position A, and the first sensor can be a contact sensor or a non-contact sensor in the prior art; wherein the contact sensor can be a rotary encoder sensor, a potentiometer sensor, a spring probe sensor, a travel switch, a two-dimensional matrix position sensor, etc. in the prior art; the non-contact sensor can be a magnetic induction sensor, an inductive sensor, a laser interferometer, an ultrasonic position sensor, a photoelectric position sensor, a GPS position sensor, etc. in the prior art; when the first sensor detects the first positioning fork, the first positioning fork of the positioning clamping unit 10 is in a closed state and has a small size; when the first sensor does not detect the first positioning fork, the first positioning fork of the positioning clamping unit 10 is in an open state rotated outward; the sensing is sensitive and easy to use.

[0029] like Figure 2 As shown, it shows the state diagram when the first positioning fork 13 rotates to the longitudinal storage position A. The first material fixing fork is vertically arranged on one side of the base, and the transmission assembly coincides with the clamping space 01 between the first pin and the second pin. It is small in size and cleverly designed. Figure 3 As shown, it shows the state diagram when the first positioning fork 13 is rotated to the horizontal fixing position B. The first positioning fork 13 is horizontally arranged on one side of the base, the transmission assembly is deviated from the clamping space 01 between the first pin and the second pin, and the first pin 131 and the second pin 132 both protrude from the outside of the base, so that the first positioning fork can be inserted and positioned in the positioning groove of the pallet.

[0030] The pallet positioning assembly is cleverly designed and is suitable for pallets with positioning grooves on the outer surfaces. It is easy to position. The rotation drive assembly drives the transmission assembly to drive the first positioning fork to rotate toward the pallet, so that the first pin of the first positioning fork is inserted into the positioning groove of the pallet and the second pin is inserted into the outer side of the pallet. Not only can the pallet be positioned, but the first pin and the second pin cooperate with each other to clamp the pallet. In the utility model, the transmission assembly is arranged between the first pin and the second pin, which effectively utilizes the space between the first pin and the second pin, making the overall structure more compact and smaller in size than the prior art.

[0031] In order to realize positioning of multiple pallets and improve efficiency, the positioning and clamping unit 10 also includes a second positioning fork 16 fixedly connected to the rotating shaft 12; the first positioning fork 13 and the second positioning fork 16 are respectively fixedly arranged at both ends of the rotating shaft 12. Among them, the first positioning fork 15 and the second positioning fork 16 can respectively position and clamp the front and rear pallets, for example, the first positioning fork and the second positioning fork are arranged front and back, the first positioning fork cooperates with the positioning groove at the rear end of the front pallet for insertion and positioning, and the second positioning fork cooperates with the positioning groove at the front end of the rear pallet for insertion and positioning, which is convenient to use; in one embodiment, the first positioning fork 13 and the second positioning fork 16 are arranged relatively overlapping to achieve synchronous clamping and smoother positioning.

[0032] Furthermore, the rotating shaft 12 runs transversely through the front and rear ends of the base 11; the first positioning fork 13 and the second positioning fork 16 are respectively located at the front and rear sides of the base 11, so that a certain distance is maintained between the front and rear trays to avoid collision between the front and rear trays.

[0033] Furthermore, the first pin 131 cooperates with the positioning groove of the pallet for insertion and positioning, and the second pin 132 is inserted into the outside of the pallet and cooperates with the first pin 131 to position and clamp the pallet. The clamping width formed between the first pin and the second pin is greater than the distance between the inner wall of the pallet positioning groove and its adjacent outer wall, which makes it convenient for the first positioning fork to easily insert and position the pallet.

[0034] Furthermore, the first plug pin 131 and the second plug pin 132 are arranged to overlap each other, which can not only provide stable positioning and clamping for the tray, but also effectively save space.

[0035] Furthermore, in order to make the structure of the pallet positioning assembly more compact, the rotating drive assembly 14 includes a rotating motor arranged above or below the first positioning fork 13. It is worth noting that the rotating motor is a prior art and will not be described in detail here. The rotating motor, the transmission assembly and the first positioning fork are arranged longitudinally, which not only reasonably utilizes the longitudinal space of the base, but also can better organize the interactive relationship between the three, so that the performance of driving the first positioning fork to rotate is improved.

[0036] Furthermore, the transmission assembly 15 includes a transmission wheel 151 fixedly mounted on the connecting shaft 133, a driving wheel 152 fixedly mounted on the output shaft of the rotating motor, and a conveyor belt 153 connected to the transmission wheel 151 and the driving wheel 152, so that the transmission is precise.

[0037] In order to be applicable to trays with various different positioning slots and to facilitate the maintenance or replacement of the first pin or the second pin, the first pin 131 or the second pin 132 is detachably connected to the connecting shaft 133; optionally, the first pin 131 and the second pin 132 can also be fixedly connected to the connecting shaft 133, which is convenient to use. Figure 4As shown, the first plug pin 131 and the second plug pin 132 both include a fixing ring 1311 sleeved on the outside of the connecting shaft 133, and a plug-in piece 1312 extending outward from the outer surface of one side of the fixing ring 1311; the fixing ring 1311 is provided with a first through hole 1313 for the fastener to pass through; the connecting shaft 133 is provided with a second through hole 1331 corresponding to and connected to the first through hole 1313; the fastener passes through the first through hole 1313 and the second through hole 1331 to fix the fixing ring 1311 on the connecting shaft 133, and the assembly and disassembly is simple.

In one embodiment, the transverse movement assembly includes two second slide rails parallel to each other, two conveyor belt assemblies that respectively drive the positioning and clamping units to move along the second slide rails, and a transmission drive mechanism that drives the two conveyor belt assemblies to rotate synchronously in the same direction. The conveyor belt assembly can adopt the conveyor belt structure in the prior art, and the transmission drive mechanism can be realized by adopting the transmission rod in the prior art and the rotating structure that drives the transmission rod to rotate. The front and rear ends of the transmission rod are respectively connected to the conveyor belt assembly through transmission wheels, and the transmission rod is driven to rotate by the rotating mechanism, thereby driving the two transmission belt assemblies to move synchronously in the same direction, thereby achieving the purpose of driving the two positioning and clamping units to move synchronously in the same direction, with good synchronization.
